Abstract

The invention relates to the electrical technical field, and especially relates to an embedded vacuum contactor with a small size; the embedded vacuum contactor comprises a vacuum bubble and an electromagnetic mechanism; the vacuum bubble top is connected with an upper soft connection, and arranged on the vacuum bubble mounting rack; the electromagnetic mechanism comprises an insulation coil, and a permanent magnet, a movable core and a movable rod arranged in the insulation coil; the movable rod penetrates the movable core and the permanent magnet, and is connected with the vacuum bubble bottom through a lower soft connection; the movable core comprises an opening spring and a closing spring arranged from top to bottom in sequence; the opening spring and the closing spring are respectively sleeved on the movable rod; an external magnetic steel housing is arranged outside the insulation coil. The electromagnetic mechanism and the vacuum bubble of the embedded high voltage contactor are directly connected, thus greatly reducing the vacuum contactor volume; the coil is casted by an epoxy resin, and the outgoing line outputs the high voltage cable connection manipulation electricity, thus isolating low voltage manipulation electricity from a high voltage environment; the permanent magnet can be attached to the movable core once closed, thus keeping the closing state, and preventing tripping caused by manipulation electricity drop out.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a small-volume embedded vacuum contactor. Background technique [0002] High-voltage vacuum contactor is a control switch for high-voltage lines, which is used to control high-voltage motors, transformers and other electrical equipment. With the demand for product upgrades and modularization, the field of electrical engineering is pursuing development in the direction of small size, modularization, and standardization. , where the commonly used high-voltage vacuum contactor is widely used as a basic device. [0003] However, in the field of 35kV high-voltage vacuum contactors, the disadvantage is that the volume is relatively large, especially when used in a box-type control cabinet. In order to ensure the safety and reliability of the high-voltage side to the ground, the design of the box-type control cabinet will increase. Larger volume, especially the size in the height d...
