Abstract
The invention relates to a low-pressure permanent magnetic vacuum load switch which comprises a box body, wherein an inner frame, a low-pressure vacuum arc extinguishing chamber and an electromagnet are arranged in the box body; the low-pressure vacuum arc extinguishing chamber and the electromagnet are installed on the inner frame; and the low-pressure vacuum arc extinguishing chamber is connected with the electromagnet through a transmission mechanism. According to the invention, a pull-push type electromagnet structure is adopted so that starting current is greatly reduced and the application range of a permanent magnetic mechanism switch is enlarged; not only an energy storing circuit is simplified, but also the cost is greatly reduced; simultaneously, because positive and negative magnetic force perform action at the same time, action reliability is greatly enhanced and action time is greatly shortened; a closing and opening coil is electrified only at the moment of closing and opening of the switch; at ordinary time, the coil is kept in the closing and opening position by means of a permanent magnet; and the loss of the coil on electrical energy is greatly reduced.
