Description
Technical field
The utility model relates to electric equipment field, particularly relates to a kind of auxiliary relay with defencive function.
Background technology
Auxiliary relay (intermediate relay): for relaying protection and automatic control system, to increase quantity and the capacity of contact.It is for transmitting M signal at control circuit.The structure of auxiliary relay and principle and A.C. contactor are basic identical, are: the main contact of contactor can lead to super-high-current, and the contact of auxiliary relay can only lead to too little current with the main distinction of contactor.So it can only be for control circuit.It does not generally have main contacts, because overload capacity is smaller.So its use is all auxiliary contact, quantity is many.New national standard is K to the definition of auxiliary relay, and old-national's mark is KA.Be generally DC power supply, minority is used Alternating Current Power Supply.
And existing auxiliary relay has dividing of 36V, 220V and 380V, in the process of using, some operative employee is because of carelessness, the auxiliary relay of 36V or 220V can be received in the circuit of 380V and used, can surpass because of the voltage using the rated voltage of auxiliary relay like this, thereby cause Relay Contactor Burning Out.
In sum, for the defect of prior art, need especially a kind of auxiliary relay with defencive function.
