Background
The working principle of the alternating current contactor is that the contact is connected and disconnected by matching electromagnetic force with the elastic force of a spring. The alternating current contactor has two working states, namely a power-off state (release state) and a power-on state (action state). When the attraction coil is electrified, the static iron core generates electromagnetic attraction force, the armature is attracted, and the connecting rod connected with the armature drives the contact to act, so that the normally closed contact breaking contactor is in an electrified state; when the attraction coil is powered off, the electromagnetic attraction force disappears, the armature is reopened, the normally open contact is closed, the normally open contact is released under the action of the position spring, all the contacts reset accordingly, and the contactor is in a power-off state. The reversible contactor is a mechanical reversible AC contactor for controlling the positive and negative rotation of a motor with larger power, consists of two standard contactors and a mechanical interlocking unit, integrates the advantages of the AC contactor and a reversible switch, is simple, safe and reliable to operate, has low cost, and is mainly used for the positive and negative rotation, the reverse braking, the constant operation and the inching operation of the motor. The existing reversible AC contactor has the defects of complex structure, unreliable performance and inconvenient assembly due to unreasonable structural design of an interlocking mechanism.
