Abstract

The invention discloses a compact high-pressure tank type rapid mechanical combination switchgear which comprises a metal shell with a hollow cavity, an inner cavity of the metal shell is of a closed structure, the inner cavity of the metal shell is filled with insulating gas, a rapid switch device is arranged in the inner cavity of the metal shell. The rapid switch device is connected with an operating mechanism, the operating mechanism is located on the outer wall of the end of the metal shell, the metal shell is provided with a conductive loop supporting cylinder, the conductive loop supporting cylinder is sleeved with a current transformer, one end of the conductive loop supporting cylinder is connected with an insulating sleeve, one end of the insulating sleeve is provided with a terminal, and the terminal is connected with the rapid switch device. According to the invention, the problems of unsafe high-altitude electricity taking and low reliability at present are solved, and the switchgear has the advantages of more convenient operation and maintenance, more convenient operation, high stability, compact structure, easy module cascade expansion and the like.

Description

technical field [0001] The invention relates to the technical field of high-voltage switches, in particular to a compact high-pressure tank-type rapid mechanical combination switchgear. Background technique [0002] At present, the fast vacuum switch based on the electromagnetic repulsion mechanism has a simple structure, fast opening and closing speed, and small on-state loss, so it has broad application prospects in many fields such as power system fault current limiting, DC circuit breakers, and phase-controlled switches. . [0003] However, when the existing fast vacuum switch is used as a fault current limiter switch device or a DC circuit breaker device, it generally uses external air insulation, and the overall device is arranged on a platform constructed of supporting insulators and cable-stayed insulators to ensure ground insulation distance; fast vacuum switches in high-pressure and ultra-high-pressure systems require the series connection of multiple module units...
