Electrical power boiler construction in Chongqing City
Electrical power boiler construction in Chongqing City.
The electric power boiler adopts the stage power adjustment by AC contactor control, and the stepless power adjustment adopts the thyristor control. The thyristor can also be used for stepped power regulation, which has the advantage of no mechanical action noise and long life. The disadvantage is that the main circuit can not be completely shut down, the overcurrent and overvoltage capability is poor, the power consumption is large, the heat dissipation is required, and the price is high.
The advantage of the AC contactor is that the main circuit can be completely electrically isolated, the ability of over voltage and over current is strong, the power consumption is small, the heat generation is small, and the price is low.
