Problems solved by technology
After the spring is used for a long time, its elastic force will gradually weaken or even disappear. If the elastic force of the spring cannot be grasped in time, when the elastic force of the spring is not enough to offset the gravity of the actuating part, it is likely to affect the normal use of the contactor. Serious safety accidents may even occur

The present invention provides an AC contactor, which includes a base frame, static iron cores respectively arranged on the base frame, a movable part with a moving iron core and a moving contact, and a moving part set up and down opposite to the moving contact. A static contact, a coil wound on the static iron core, an elastic member arranged between the static iron core and the moving iron core, the static iron core is arranged up and down opposite to the movable member; the The contactor also includes a controller, a reading device connected to the controller, and an identification piece arranged opposite to the reading device; the reading device is arranged on the movable part, and the identification piece includes several Each of the position indicating units is vertically fixed on the chassis; the reading device obtains its real-time position height by reading the corresponding position indicating unit. The invention can grasp the elastic condition of the elastic part at any time, facilitate timely repair or replacement when the elastic part is insufficient, and can ensure the normal use of the AC contactor.
Description
technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an AC contactor. Background technique [0002] A contactor is an electrical appliance that uses a current flowing through a coil to generate a magnetic field to close the contacts to control the load. It is divided into AC contactors and DC contactors. A conventional electrical contactor consists of two functional parts: a contact part and an actuation part. The contact part is the load current carrying part of the contactor, which is made of low resistance metal. Generally, the contact part maintains its original state due to gravity or other forces. The actuation member provides the driving force to switch the contact member to its opposite state and maintains the contact member in the opposite state by counteracting gravity or other force. Typically, the actuation member is energized by an input current. After the current is removed, the actuation member is de...
