Problems solved by technology

[0002] The vacuum contactor uses a vacuum interrupter to extinguish the arc to frequently connect and cut off the normal working current. It is usually used for long-distance connection and disconnection of 6kV, 380V (660V, 1140V) AC motors that frequently start and stop at medium and low voltages. The existing vacuum contactor has the disadvantages of slow closing speed and easy heating of the coil, so a new type of vacuum contactor is urgently needed

Abstract

The invention provides a high-voltage AC vacuum contactor. The high-voltage AC vacuum contactor comprises a vacuum chamber, an installation frame, a hinged bearer A, a cylinder, a connecting rod, a roller A, a flat plate, a trapezoidal slide block, two rollers and the like, wherein the vacuum chamber is a vacuum enclosed casing made of an insulation material, the casing is internally provided with two copper pins, the end, which is exposed out of the vacuum chamber, of each copper pin is connected with a wiring terminal, one of the wiring terminals is taken as an input end, and the other is taken as an output end. According to the invention, the opening and closing of the contactor are controlled through the cylinder, and at the same time, the contact speed of moving contacts is enabled to be faster through the speed amplification effect of the trapezoidal slide block and the connecting rod.

Description

technical field [0001] The invention relates to the technical field of contactors, in particular to a high-voltage AC vacuum contactor. Background technique [0002] The vacuum contactor uses a vacuum interrupter to extinguish the arc to frequently connect and cut off the normal working current. It is usually used for long-distance connection and disconnection of 6kV, 380V (660V, 1140V) AC motors that frequently start and stop at medium and low voltages. The existing vacuum contactor has disadvantages such as slow closing speed and easy heating of the coil, so a new type of vacuum contactor is urgently needed. Contents of the invention [0003] In view of the above problems, the present invention provides a high-voltage AC vacuum contactor, which controls the opening and closing of the contactor through the cylinder, and at the same time, through the speed amplification of the trapezoidal slider and the connecting rod, the contact speed of the moving contact is faster. ...
