Which socket should the desktop computer voltage regulator be plugged into correctly? This problem bothers many users. Desktop computer voltage regulators plugged into different sockets may affect the stability of the computer and even cause safety hazards. Next, PHP editor Yuzai will introduce in detail which socket the desktop computer voltage stabilizer is plugged into and what needs to be paid attention to, to help everyone use the voltage stabilizer correctly and ensure the safe and stable operation of the computer.
1. Plug the power cord of the voltage stabilizer into the mains 220. First check if it is working properly and turn off the power. 2. Plug the computer power cord into the three-hole socket of the voltage stabilizer. 3. Turn on the voltage stabilizer. Press the quick start button to start, 4 turn on the computer.
Is your computer’s voltage regulator buzzing? The reasons are:
1. The voltage regulator makes a slight buzzing sound, which is generally normal. If it is a continuous voltage regulator, the motor rotates with the carbon brush when the voltage regulator adjusts the voltage. The friction sound caused by the rotation of the coil inside the voltage regulator will produce a buzzing sound.
2. Another situation is that the cooling fan of the voltage regulator has too much dust or fails. This phenomenon will also occur. You only need to disassemble and clean the cooling fan.
The poster first connected the power cord of the voltage stabilizer to the corner socket, and then connected the power cable of the computer host to the voltage stabilizer and it was OK. I didn’t see you write down the voltage stabilizer model, but generally small voltage stabilizers with several thousand volts have a switch button on the front panel. Remember to turn on the voltage stabilization function
Computer voltage regulators are not protected against lightning strikes.
Absolutely not. The voltage range stabilized by the voltage stabilizer is very small. Lightning is a voltage of tens of thousands of volts. The components have rated working voltages. If it is too large, it will burn out. However, if you connect a voltage stabilizer , lightning usually damages your voltage regulator, so your loss is about two to three hundred. In fact, the grounding is generally the metal grounding of electrical appliances to prevent electric shock. If lightning is transmitted through wires, it has no effect at all.
1. Open the package and first check whether the casing, meter, switch, indicator light, button, terminal block, etc. are damaged. Use only those without damage.
2. Plug the input terminal into (or connect to) the power distribution board, and install a fuse that matches the power of the device on the user's power distribution board to ensure the safety of electricity.
3. Connect the power supply of the electrical equipment to the output end of the device. Pay attention to whether the applicable voltage of the electrical appliance is 220V or 110V. Do not connect it incorrectly.
4. First turn on the power switch of the voltage regulator. The working indicator light and delay indicator light are on. There is no power output. Power will be supplied after 3-7 seconds. Observe whether the indicator light indicates 220V normally. When the output voltage is around normal (220V), turn on the power switch of the electrical equipment. This voltage regulator can automatically adjust the voltage and provide normal power supply.
5. When the electrical equipment is not used for a long time, please turn off the power switch of the electrical equipment and the power switch of the voltage stabilizer to reduce power consumption and extend the service life of the voltage stabilizer.
6. This voltage regulator must not be overloaded. When the mains voltage is low, the output capacity is reduced, and the load of the voltage regulator should be reduced accordingly.
7. When using electrical appliances such as refrigerators, air conditioners, water pumps and other equipment with motors running, a voltage regulator with a capacity of more than 3 times should be selected to prevent the starting current of the equipment from exceeding the voltage regulator fuse current or overcurrent protection circuit breaker current. The voltage regulator fuse blows or the circuit trips and it cannot work.
8. The wire connected to the voltage regulator should have sufficient cross-section to prevent heating and reduce voltage drop. Voltage stabilizers with a capacity of 2KVA or above use terminal connections. A single copper wire should be used, and the terminal screws should be tightened as much as possible to prevent the connection from heating.
9. Some voltage regulator panels are equipped with a voltage detection button. Press the button and the voltmeter will indicate the input voltage, and you can directly observe the mains power condition.
10. The three terminals A, B, and C on the left side of the three-phase voltage regulator are connected to the input three-phase phase line (live wire), the three terminals X, Y, and Z on the right side are connected to the load, and the two terminals in the middle are connected to the input and output common zero. Wire. Wire the single-phase voltage regulator as shown on the terminal cover.
11. When the voltage detection button on the three-phase voltage regulator panel is pressed in and out, it indicates the AB and AC phase line voltages (380V) respectively. The button and universal conversion can only be regarded as whether the two voltages are in normal use.
12. Whether it is a single-phase or three-phase voltage stabilizer, after connecting all input and output lines, you should first turn off the power switch of the load (electrical appliance), then turn on the voltage stabilizer, check that the output voltage is normal, and then Turn on the power switch of the load.
Plug it in again and the voltage regulator has power again, and the input voltage and output voltage meter show normal. There will be no overheating, burning or smoking after 20 minutes, so it should still be usable. But it is best to dip the transformer into paint once
Principle of generator voltage stabilizing box: The electromagnetic induction principle of cutting magnetic lines of wire to induce electric potential is used to convert the mechanical energy of the prime mover into electrical energy for output.
Synchronous generator consists of two parts: stator and rotor. The stator is the armature that generates electricity, and the rotor is the magnetic pole. The stator consists of an armature core, evenly distributed three-phase windings, a machine base and an end cover.
The rotor is usually a hidden pole type and consists of an excitation winding, an iron core and a shaft, a retaining ring, a center ring, etc.
The number of poles of turbine generators is mostly two-pole, and there are also four-pole.
The excitation winding of the rotor is supplied with DC current, which generates a magnetic field close to a sinusoidal distribution (called the rotor magnetic field), and its effective excitation flux intersects with the stationary armature winding.
When the rotor rotates, the rotor magnetic field rotates together. With each revolution, the magnetic lines of force sequentially cut each phase winding of the stator, and three-phase AC electric potential is induced in the three-phase stator winding.
When the generator is running with a symmetrical load, the three-phase armature currents are combined to produce a rotating magnetic field with synchronous speed.
The interaction between the stator magnetic field and the rotor magnetic field will produce braking torque.
The mechanical torque input from the steam turbine overcomes the braking torque and performs work. Generators can produce both active and reactive power. Therefore, adjusting the active power requires adjusting the steam intake of the turbine.
The strength of the rotor magnetic field directly affects the voltage of the stator winding. Therefore, the rotor current must be adjusted to adjust the generator terminal voltage or the reactive power of the generator. The geometric sum of the active power and reactive power of the generator is called the apparent power.
The ratio of active power to apparent power is called the power factor (power factor) of the generator. The rated power factor of the generator is generally 0.85. The system that supplies DC to the generator rotor to establish rotor excitation is called the generator excitation system. The excitation methods of large generators are divided into:
① other excitation system;
② self-parallel excitation system.
Its excitation is generated by an AC generator coaxial with the generator, which is rectified into DC power to excite the generator rotor.
Self-parallel excitation magnet is to step down the alternating current from the generator end through a transformer, and then rectify it into direct current, which is used as the excitation of the generator rotor
The working principle of this voltage stabilizer is voltage negative feedback. When the voltage is high, the control circuit controls the voltage-regulating motor to reduce the voltage to the rated value. When the voltage is low, the control circuit controls the voltage-regulating motor to increase the voltage to the rated value. If the voltage deviates from the rated value, generally The voltage sampling integrated circuit is broken, or the relay and peripheral circuit controlling the motor are damaged.
Similar points: both voltage regulators and ups have voltage stabilizing functions. When the input voltage fluctuates within a certain range, the output can be guaranteed to be basically stable. The differences in 220V are:
1. The accuracy of ordinary voltage regulators is low and is not suitable for use in equipment with strict power requirements such as computers, while the accuracy of UPS is high.
2. The voltage regulator does not have a backup power supply function. If the mains power fails, it will have no power output. The UPS is equipped with batteries. When the mains power fails or is seriously under-voltage, the battery will immediately supply 220 voltage through the boost circuit to ensure that the equipment can work normally for a period of time. The length of time is determined by the battery capacity. Summary: Voltage stabilizers can be used in areas with unstable voltage, and UPS is the best choice. Ordinary voltage stabilizers whose performance cannot meet the requirements of computers are not needed. UPS is used in areas with frequent severe undervoltage or power outages.
If it hasn’t been turned on for a long time, the hardware may be broken.
1. Check whether the power supply fan is rotating normally. The power supply may be broken if it is rotating normally.
2. Is the motherboard light on? When the motherboard is turned on normally, there will be a medium-long beep; (it does not indicate a motherboard problem) 3. Check whether the CPU indicator light flashes normally; (CPU cannot start normally) 4. Is the screen normal? Display; (There is no problem with the hardware, check whether the system is normal) 5. After booting normally, the speaker can be played normally.
