Relay coil fault solution

Relay type is quite a lot, according to different classification methods will have different performance of the relay, generally speaking, relay in use can fully play the remote control, telemetry, communication, automatic control and other functions. Coil is the necessary part of the relay, then, if it has a fault, how to solve it?

The relay is composed of two parts: coil and contact group. There are many kinds of coils used. The relay coil is represented by a rectangular frame symbol in the circuit. If there are two coils in the relay, two parallel rectangular boxes are drawn. At the same time, in the rectangular box or rectangular box next to mark the relay text symbol "J"". There are outsourcing, and there is no outsourcing, coil should be separate, placed in special appliances, if the collision is connected, when separated, will cause disconnection. In the electromagnetic riveting system, hand press and press pressure adjustment should be moderate, too much stress caused by the coil wire or coil frame cracking, distortion, winding breakdown. If the pressure is too small, the winding will be loose and the magnetic loss will increase. Multiwinding coil is generally used in different colors or lead. When welding, attention should be paid to distinguish, otherwise it will cause coil welding error. A coil with an initial end requirement, usually marked with a mark to indicate the beginning. Assembly and welding should be noted, otherwise it will cause solid relay level reversal.
