Description
Technical Field
The utility model relates to an ac contactor, especially an ac contactor of taking control by temperature change.
Background
The existing alternating current contactors are all provided with an electromagnetic attraction device, a fixed contact and a moving contact, and after a coil of the electromagnetic attraction device is electrified, the moving contact is driven to move so as to enable the moving contact and the fixed contact to be mutually connected or disconnected. Therefore, the working states of the coil, the static contact and the moving contact directly reflect the performance of the alternating current contactor. In practical applications, the ac contactor fails mainly due to two reasons: one is that the coil blows after passing a large current (i.e., the coil opens); the other is that the passing current between the static contact and the moving contact is too large, so that the contact part of the static contact and the moving contact generates heat and is fused and cannot be separated.
