Abstract

The invention relates to a single-stage direct actuating low-voltage permanent magnet vacuum load switch which comprises a base, a permanent magnet operating mechanism, a low-voltage vacuum arc-extinguishing chamber and a direct actuating component. The permanent magnet operating mechanism is connected to the base. The low-voltage vacuum arc-extinguishing chamber is connected with the base and the permanent magnet operating mechanism through the direct actuating component. The single-stage direct actuating low-voltage permanent magnet vacuum load switch has the advantages that the switch is elongated in overall structure, miniaturization of low-voltage switches is realized, transmission components are simple, reliable and smaller in size, and the switch is suitable for integrated design of equipment in narrow space and complete equipment, especially suitable for being used as a low-voltage load control switch inside a transformer.

Description

technical field [0001] The invention relates to a single-stage direct-acting low-voltage permanent magnet vacuum load switch, in particular to a bar-shaped vacuum arc-extinguishing switch using a permanent magnet operating mechanism for low-voltage load control. Background technique [0002] In the prior art, most of the three-phase low-voltage vacuum switches are frame-type structures, and electromagnetic operating mechanisms are commonly used. This type of switch takes up a lot of space, which is not suitable for occasions with small spaces and is not conducive to the integrated design of complete sets of products. The coil needs to be charged for a long time to maintain the state, so the electric energy is inevitably lost. Contents of the invention [0003] In response to the above needs, the purpose of the present invention is to solve the above technical problems and provide a low-voltage vacuum load control switch with a direct-acting mechanism that has few transmiss...
