When existing traditional DC contactors work, pull the breaking process should arcing

Existing traditional DC contactors work, pull the breaking process should produce an arc , and the contactor coil has to rely on the pull to keep energized contactor closed state , there is a coil power consumption, power run when noise, there is a strong arc shortcomings off when the main contact circuit , so not only caused a lot of energy waste , pollution of the surrounding environment, but also greatly reduces the electrical contactor life . This article is based on the original DC contactor on its  power transformers  and no arc transformation , which developed a non- permanent magnet DC arc contactor. It uses NdFeB rare earth permanent magnet  mcb circuit breaker  and high- power electronic devices , such as the combination of acting on the contactor electromagnetic system . The use of magnetic flux generated by the permanent magnet to pull the state to maintain the coil is energized only when breaking moment , the rest of the time there is no  Circuit breaker  the coil from the fundamental solution to the problem of power consumption . Through the use of special measures to release a good solution to power and voltage protection issues such as permanent magnetic contactor , contactor so it has a strong magnetic pull , permanent magnet to keep saving , noise-free function. Meanwhile , in the original contactor in parallel across a triac , contacts and thyristor action sequence by using a special control unit has the strength of electrical isolation of control .
