Abstract

The invention discloses a modular permanent magnet vacuum feeder switch. The modular permanent magnet vacuum feeder switch is provided with a switch body, wherein the switch body comprises a breaker (1) and a controller (2), the breaker (1) is provided with a breaker shell (3), three containing cavities are arranged in the breaker shell (3) in sequence from top to bottom, a permanent magnet device (4), a vacuum pipe (6) connected with the permanent magnet device (4) through a connecting mechanism (5) and a current transformer (7) connected with the vacuum pipe (6) are arranged in each containing cavity, the controller (2) is provided with a controller box (8) which is matched with the breaker shell (3), an electric wire is connected between the controller box (8) and the breaker shell (3), and the controller box (8) and the breaker shell (3) are locked together through a locking mechanism. The modular permanent magnet vacuum feeder switch has the advantages that the size is small, maintenance is convenient, a control system is arranged, and mechanical and electronic integration is achieved.

Description

technical field [0001] The invention relates to the technical field of feed switches, in particular to a modular permanent magnet vacuum feed switch. Background technique [0002] At present, mine vacuum feed switch is divided into permanent magnet type and mechanical holding type. It is widely used in mine voltage 3300V, 1140V, 660V, 380V, current below 1000A, ground power distribution system and starter motor circuit. The existing feed switch is composed of a circuit breaker body (independent type), a power supply to the body, a power supply of a protector, a protector (comprehensive protection), a three-phase reactor, a choke coil (shared with a voltage transformer), and a combined Gate relay, intermediate relay, rectifier bridge, leakage sampling board, capacitor resistor and other related components, while the circuit breaker in the feed switch is generally an electromagnet with three-phase (pieces) vacuum tubes, which are attracted by electromagnets or permanent magnet...
