There are many types of relays, which have different performances according to different classification methods. Generally speaking, relays can fully play the functions of remote control, remote measurement, communication and automatic control in use. The coil is a necessary part of the relay, so what if it fails? Relays are composed of two parts: coil and contact group. There are a variety of coils used. Relay coils are represented by a long box symbol in the circuit. At the same time in the long box or the long box next to the text symbol "J" relay. If there is outsourcing or not, the coil shall be separated and placed in a special appliance. If the coil is connected by collision, it will break the wire when separated. When the electromagnetic system rivets, the pressure adjustment of the hand press and press should be moderate, too high pressure causes the coil broken line or coil frame cracking, deformation, winding breakdown. Too little pressure will cause loose winding and increased magnetic loss. Multi-winding coil is usually made with different colored leads. When welding, should pay attention to distinguish, otherwise will cause the coil welding wrong. Coil with beginning end required, usually marked by a marking method. Care should be taken during assembly and welding; otherwise, the solid-state relays will be of opposite class. |
