Nader Circuit Breaker

I would grade trip summarizes the analysis of the causes of the following reasons for your reference study. The first case: the main switching points less than the sum of the load switch. Second case: the main switch has no sub-switch leakage protection device, with the electrical leakage when the ma...

(1) induction heating, the original is placed on the body of the tank, the outer tank passing a current through the coil is wound, the use of eddy current heating tank skin to dry. Article tank wall may be a plurality of pads asbestos, asbestos wire is wound on the strip. Induction heating power requ...

Breaker interrupter way roughly divided into two ways. 1. Formula horizontal arc blow. With horizontal blowing interrupter switch, when opening the movable, stationary arcing contacts separate, the heat of vaporization and decomposition of the oil. The pressure in the arc chamber rapidly increases, w...

Air switch is very important in low voltage distribution network and the power of one electrical drive system, which combines the control and protection functions in a variety of. In addition to complete and break the contact circuit, a short circuit or electrical equipment can still occur. Severe ov...

First calculate the total of all electrical power P, the calculated total current number of A I = P / U, when the switch is selected to be greater than the total amount of current leakage, cut to have a certain margin, or installed in other words on the electrical will bear the remaining leakage curr...
