An automatic oil supply and flame extinguishing device for a generator set and grid power supply switching device

Abstract

The invention relates to an automatic oil supply and flameout device for a power supply switching device of a power generator set and an electricity network. The automatic oil supply and flameout device has the advantages of high electromagnetic interference resistance performance and high long-time work stability and comprises an oil supply and flameout controller XQ, wherein the oil supply and flameout controller XQ is connected with a negative electrode of a 24V direct current power supply, a positive electrode of the 24V direct current power supply switches an auxiliary normally closed contact 2KM2 through the serially connected power generator set power supply and switches an auxiliary normally closed contact 1KM1 of an alternating current contact KM1 through the electricity network power supply, and is then connected with one end of a normally open contact A1 of an electricity network test middle relay CA and one end of a normally closed contact A5 of an electricity network test middle relay CA, and the other end of the normally open contact A1 of the electricity network test middle relay CA and the other end of the normally closed contact A5 of the electricity network test middle relay CA are respectively connected with the oil supply and flameout controller XQ. The automatic oil supply and flameout device has the advantages that the structure is simple, the manufacturing cost is low, economic performance is realized, and the automatic oil supply and flameout device conforms to the national conditions in China.

Description

technical field [0001] The invention relates to an automatic fuel supply and flame-out device for a generator set and a grid power supply switching device, which belongs to the field of electronic technology. Background technique [0002] The working principle of the automatic oil supply and flameout device of the generator set and grid power supply switching device is as follows: In the state of grid power supply, if the grid is powered off, the fuel supply and flameout controller XQ will send out the flameout lever and open the throttle to ensure the normal start of the generator; In the power supply state of the generator, if the power comes from the power grid, the oil supply and flameout controller XQ will automatically tighten the flameout lever of the generator set, close the throttle, and the generator set will shut down. [0003] The automatic oil supply and flame-out device of the current generator set and grid power supply switching device has poor anti-electromag...

Problems solved by technology

[0003] The automatic oil supply and flame-out device of the current generator set and grid power supply switching device has poor anti-electromagnetic interference performance, poor long-term working stability, and is prone to failure, which seriously affects the normal operation of production and life; there are also some generator sets and grid power supply switching devices. The performance of the automatic oil supply and flameout device is stable, and there are few failures, but the structure is often complicated and the cost is high, which does not meet the national conditions of our country.
