Abstract

The invention introduces a monostabillity permanent-magnet mechanism intelligent control apparatus and a control method thereof. The monostabillity permanent-magnet mechanism intelligent control apparatus is characterized by consisting of a control unit (1) and an energy storage unit (2) which are connected by a core aviation plug with a cable line (7); the control unit (1) consists of a control electrical plate (3), a bridge type inverter unit (4) and power supply modules (5), (6) and (7); and the energy storage unit (2) consists of an energy storage capacitor (15) and a charge control unit (16). The invention provides a monostabillity permanent-magnet mechanism intelligent control apparatus with long service life, high intelligentization and high reliability and the control method thereof and can overcome the disadvantages of the existing monostabillity permanent-magnet mechanism intelligent control apparatus and the existing control method of short service life, low reliability, uncontrollable performance, etc.

Description

technical field [0001] The invention relates to an intelligent control device and a control method of a monostable permanent magnet mechanism, which belong to the intelligent control device and control method of a monostable permanent magnet mechanism of a railway electric traction vacuum circuit breaker. Background technique [0002] The existing permanent magnet mechanisms used in railway special vacuum circuit breakers mostly adopt the bistable form, which is bulky and inconvenient to install. The monostable permanent magnet mechanism has the characteristics of small size and is suitable for loading on vacuum circuit breakers limited by space, especially suitable for railway vacuum circuit breakers. However, the current monostable permanent magnet mechanisms all use switching elements with contacts , the current control unit cannot be loaded, and the opening and closing action of the permanent magnet mechanism can only be completed by simply changing the direction of the ...
