Permanent magnet vacuum arbitrary phase-change switch

Abstract

The invention provides a permanent magnet vacuum arbitrary phase-change switch which is composed of a switch pedestal (1), an A permanent magnet operating mechanism (2), a B permanent magnet operating mechanism (3), an A vacuum arc-extinguishing chamber (4), a B vacuum arc-extinguishing chamber (5), a C vacuum arc-extinguishing chamber (6), a D vacuum arc-extinguishing chamber (7), an A crank arm (8), a B crank arm (9) and an intelligent controller (10). Advantages of the permanent magnet vacuum arbitrary phase-change switch are that the permanent magnet vacuum arbitrary phase-change switch is maintenance-free, high in insulating property, high in voltage withstanding, small in size, high in breaking capacity, high in on-off current, long in the service life and safe and reliable. The permanent magnet mechanisms are maintained without power consumption so as to be energy-saving and environment-friendly. All the vacuum arc-extinguishing chambers are affected by the crank arm movement structure and a conductive bar commonly so that mechanical interlocking is formed, and single-phase output is safe and reliable. The control system is intelligent and easy to install.

Description

technical field [0001] The invention relates to the field of permanent magnet switches, in particular to a permanent magnet vacuum arbitrary phase change switch. Background technique [0002] At present, the contacts of various electrical switches commonly used in the market are in the air, the on-off current is small, and arc light will be generated when the contacts are on and off the circuit, which is easy to burn out the contacts. The existing vacuum contacts The moving contact of the switch uses a telescopic rubber sleeve to help the moving contact and the static contact contact or disconnect, and play a role of sealing. The expansion and contraction of the telescopic rubber sleeve for many times will easily cause the rubber to age and rupture, causing the switch to be scrapped, and the volume is relatively large. Generally, there is only one set of contacts in each vacuum body, and the cost is high. The switches on the market can only have three inputs and three outp...
