The working principle of the voltage regulator

Author:


The voltage regulator is an adjustable auto-transformer structure, and the carbon brush of the voltage regulator is assisted by the handwheel spindle and the brush holder. The coil is evenly wound on the annular iron core, the carbon brush is closely matched with the polished surface of the coil under the action of the spring pressure, and the rotating shaft drives the brush holder to make the carbon brush slide along the surface of the coil and change the contact position of the carbon brush, that is, change The turns ratio of the primary and secondary coils enables the output voltage to obtain smooth and infinity adjustment within the adjustment range, so as to achieve the purpose of voltage regulation.

pressure regulating method of use:
1. To distinguish between the input end and the output end;
2. adjust the output to the low end before connecting to the power supply;
3. Access the power supply at the input end according to the requirements of the voltage regulator;
4. Slowly adjust the voltage at the output end to make the voltage at the output end meet the requirements of the electrical appliance;
5. Disconnect the power supply of the input terminal;
6, access to electrical appliances;
7. Adjust the voltage again as required.

The working principle of the voltage regulator is actually an autotransformer. The voltage at the input terminal remains unchanged, and then a part of the voltage is taken out from the input coil as the output. When the number of turns of the coil changes due to the movement of the sliding arm on the input coil, the output voltage is also changed. Change, so as to achieve the purpose of adjusting the output. but it must be emphasized that,
1. The public end of the high voltage transformer must be the zero line, otherwise it will easily lead to electric shock accidents,
2. The voltage regulator is not electrically isolated. It must be used with caution and must have professional knowledge.

Gas self-closing valve, can you use it?

The gas self-closing valve is installed on the indoor gas pipeline of residents. It is generally installed behind the gas meter and in front of the gas appliance. When the gas supply pressure of the gas pipeline is under-pressure or over-pressure, it will automatically close without electricity or other external power. Cut off the gas source, which can effectively prevent gas leakage and issuance accidents.
