The regulator is a device that stabilizes the output voltage. Regulator by the regulator circuit, control circuit and servo motor and other components. When the input voltage or load changes, the control circuit to sample, compare, zoom, and then drive the servo motor rotation, so that the regulator carbon brush position changes, by automatically adjust the coil turns ratio, thus maintaining the output voltage stability.
The regulator has a large number of tens to hundreds of kilowatts of AC voltage regulator, is the supply of large-scale experimental and industrial, medical equipment, power supply. There are also a few watts to several kilowatts of AC voltage regulator, is a small laboratory or home appliances to provide high-quality power supply. Whether it is a large or home regulator, do you know how to use and maintain it? Let's take a look at it.
Regulator installed
1, the Chengdu regulator input connected to the power distribution board, and in the user power distribution board installed in line with the instrument power rate of the fuse to ensure safe use of electricity.
2, the power supply of the electrical equipment connected to the output of the instrument, pay attention to the rated input voltage of the appliance should be consistent with the output of the Chengdu regulator, not wrong.
3, first turn on the power switch of the regulator, the work indicator light. Observe the voltmeter indicates whether the value is normal. Output voltage is normal, and then open the power supply power switch, the regulator that can automatically adjust the voltage, the normal power supply.
4, when the electrical equipment is not used for a long time, please turn off the power switch of power equipment to reduce power consumption and extend the life of the regulator.
5, the regulator shall not be overloaded. When the mains voltage is low, the output capacity is reduced and the regulator load should be reduced accordingly.
6, the election of electrical appliances are refrigerators, air conditioners, pumps and other motor running equipment, should choose more than 3 times the capacity of the regulator, so as not to drive the device current exceeds the regulator fuse current or overcurrent protection circuit breaker current regulator Fuse blown or circuit breaker trip or pressure drop too large to work.
7, with the regulator connected to the wire should be sufficient surface to prevent heat and reduce the pressure drop. Capacity of more than 2KVA regulator with terminal connection, should use a single copper wire, and try to tighten the terminal screws to prevent the connection heat.
8, whether it is single-phase or three-phase voltage regulator, connected to all input and output lines, you should first turn off the load power switch, and then turn on the regulator, check the output voltage is normal, And then turn on the power switch of the load.
Regulator Usage Precautions
1, do not use too high load;
2, please use enough wires;
3, please be careful to connect the input voltage and the output of the instrument;
4, equipment and voltage regulator to the output voltage to be unified;
5, please choose a good input voltage switch and power supply voltage the same;
6, if the fuse burned, check the load equipment;
7, to use the same fixed fuse, can not use non-rated fuse or wire;
8, installed in a dry and ventilated place.
