Vertical telescopic pneumatic high-voltage isolating switch

Abstract

The invention discloses a vertical telescopic pneumatic high-voltage isolating switch. The isolating switch comprises a static contact, a post insulator, a conductive arm, a main conductive base and apneumatic mechanism part, wherein one end of the post insulator is provided with a static contact, and the main conductive base is mounted at the other end; the conductive arm and the pneumatic mechanism are mounted on the main conductive base; the conductive arm is driven by the pneumatic mechanism, and the pneumatic mechanism comprises a speed reducer, a transmission connecting lever and an airpressure control system; the air pressure control system is connected with an input shaft of the speed reducer, an output shaft of the speed reducer is connected with one end of the transmission connecting lever, and the other end of the transmission connecting lever drives the conductive arm to move. The isolating switch is small in occupied space, low in cost, stable and flexible in operation,safe, reliable and convenient to maintain.

Description

technical field [0001] The invention relates to the field of isolating switches, more specifically, to a vertical telescopic pneumatic high-voltage isolating switch. Background technique [0002] At present, with the rapid development of the national economy, electricity, as a clean energy, is in increasing demand. Both the State Grid Corporation of China and China Southern Power Grid Corporation have increased their investment in power grid facilities, and the high-voltage switchgear industry has ushered in new development opportunities. Power facilities are developing towards higher voltage levels and longer transmission distances, which requires supporting construction suitable for higher Voltage level, smarter electrical test station. In the past, the transmission mode of the high-voltage disconnector used in the electrical test station was mainly electric and manual. There are also some problems in this conventional transmission mode, as follows: [0003] 1. High sp...
