Problems solved by technology

With the introduction of the tentative reclosing operation, there is a strong demand for an operating mechanism that is used for quick opening immediately after closing, that is, in the case of short-term closing. However, the opening speed of the traditional operating mechanism is slow, and only the closing The two operating commands of brake and opening cannot meet the requirements, and a new type of operating mechanism needs further research

Abstract

The invention discloses a dual-mono-stable combination permanent magnetic operating mechanism capable of realizing short-time closing and a method. The mechanism comprises a non-magnetic casing (18),a mono-stable permanent magnetic mechanism (19) disposed inside the non-magnetic casing (18), a non-magnetic material spacer (9), an subsidiary mechanism (20), a guide rod (1) which penetrates throughthe non-magnetic casing (18) and is slidably connected with the non-magnetic casing (18), and a spring support post (17) which is wrapped around the guide rod (1) and is in rigid connection with thenon-magnetic casing. The permanent magnetic operating mechanism is advantaged in that the subsidiary mechanism (20) is added, closing, opening and short-time closing command modes are provided, closing and opening operation employs a traditional mode, short-time closing operation employs a novel mode, the subsidiary mechanism (20) is further arranged for facilitating operation, the closing holdingtime is greatly shortened, the mechanism opening motion time is further shortened, and the short-time closing result is finally realized.

Description

technical field [0001] The invention relates to a double monostable combined permanent magnet operating mechanism capable of realizing short-time closing, which belongs to the field of medium-voltage vacuum circuit breakers. Background technique [0002] With the advantages of small size, light weight, suitable for frequent operation, and no maintenance for arc extinguishing, vacuum circuit breakers quickly occupied the medium-voltage circuit breaker market and further developed into the high-voltage field. The operating mechanism of the vacuum circuit breaker usually has three types: electromagnetic type, spring type and permanent magnet type. Among them, the permanent magnet operating mechanism has attracted people's attention increasingly due to its advantages of high reliability, low energy consumption, maintenance-free, and synchronous operation. With the introduction of the tentative reclosing operation, there is a strong demand for an operating mechanism that is used...
