Embodiment 1

[0019] A kind of bimetal temperature relay, its composition comprises: shell 1, described shell 1 is connected with disc bimetal 2, described disc bimetal 2 is connected with movable contact 8, and described movable The contact 8 is connected to the conductive sheet 3, the shell 1 is connected to the connecting sheet 4, the connecting sheet 4 is connected to the insulating gasket A5, the insulating gasket A5 is connected to the insulating gasket B7, and the insulating gasket A5 is connected to the insulating gasket B7. Pad B7 is connected with the static contact.

Embodiment 2

[0021] According to the bimetallic temperature relay described in Embodiment 1, the connecting piece 4 is connected to the movable contact 8 with an insulating gasket A5 and an insulating gasket B7 in the middle, and the movable contact 8 is connected to the insulating gasket B7. The static contacts 6 are in contact.

Embodiment 3

[0023] According to the method of embodiment 1 and the bimetal temperature relay described in embodiment 1, the method includes the following steps: there is a bimetal inside, and the bimetal is composed of two different linear expansion coefficients. It is the active layer, and the right side is the passive layer. The movable contact is riveted on the disc-type bimetal. When the temperature of the heating part of the motor rises, the heat generated is transmitted to the internal bimetal through the shell. When the overheating temperature is reached, the bimetal It begins to deform, and the bimetal strip and the moving contact jump away instantly to the left in the figure. The moving contact and the static contact are the connection points connected in series with the relay coil circuit. After disconnection, the relay loses power and the moving contact of the relay breaks. Open the load circuit of the motor, protect the load of the motor, cut off the power of the motor, and a...
