Abstract

The invention relates to environment-friendly type fixed-sealing integrated and modularized vacuum looped network switch equipment comprising a cabinet body, a sleeve pipe with a main bus, a vacuum switch, an isolating switch, a current transformator and a ground switch, wherein the sleeve pipe with the main bus is arranged in the cabinet body; the vacuum switch and the isolating switch are fixedly sealed into integrated modules; the vacuum switch comprises a fixed sealing type vacuum arc extinguish chamber, an insulating pull rod and a vacuum switch operation mechanism, wherein the vacuum switch operation mechanism is linked with the insulating pull rod, the upper end of the insulating pull rod is connected with the dynamic end of the vacuum arc extinguish chamber, the static end of the vacuum arc extinguish chamber is connected with the insulating switch, the insulating switch is connected with the sleeve pipe with the main bus, and dynamic end of the lower end of the vacuum arc extinguish chamber is connected with the lower wire leading-out end of the vacuum switch through first flexible connection; and the ground switch is connected with a link mechanism linked with an insulating switch operation mechanism. The invention can reduce occupying space and production cost and has good environmental-friendly property.

Description

Technical field [0001] The invention relates to a vacuum ring network switch equipment. Background technique [0002] At present, the vacuum ring main unit in the domestic market has a relatively large volume. Generally, the vacuum switch and the isolating switch are two independent electrical components, which are connected by wires when used in combination. Therefore, the ordinary ring main unit has a relatively large volume and high cost. Can not meet the requirements of the miniaturization of the ring main unit; in order to realize the miniaturization of the ring main unit, currently only SF6 gas filling cabinet can be used. By filling the ring main unit with SF6 gas (sulfur hexafluoride), the vacuum switch and isolation switch can be reduced The distance between the conductors and the ground to avoid arc discharge, but SF6 gas is one of the environmentally damaging gases recognized by the international convention and should be restricted and gradually eliminated. [0003] The...
