Abstract

The invention discloses an environment-friendly gas insulation ring main unit which comprises a cabinet body, a three-position switch, a three-position mechanism, a circuit breaker main loop and a circuit breaker mechanism, the three-position switch, the three-position mechanism, the circuit breaker main loop and the circuit breaker mechanism are installed in the cabinet body, and an interlocking device is connected between the three-position mechanism and the circuit breaker mechanism and is used for preventing hot-line operation of the three-station mechanism. The three-station switch comprises an insulating main shaft, an indicating device comprises an indicating main shaft, the insulating main shaft is connected with the indicating main shaft, a traditional three-station structure is optimized, the depth of the switch is increased, and the distance between phases and the distance to the ground of isolation knives are guaranteed; an isolation knife structure suitable for environment-friendly gas is designed to guarantee that temperature rise is qualified; for a conductive standard component on the isolation knife, an electric field voltage-sharing accessory is designed, so that the standard component accords with the insulation requirement level specified by the state.

Description

technical field [0001] The invention belongs to the field of an environment-friendly gas-insulated ring network cabinet, and relates to an environment-friendly gas-insulated ring network cabinet. Background technique [0002] Since the 1950s, the development of medium-voltage switchgear has gone through stages such as open type, box type, and metal-enclosed type. Covering, the current innovation and technological progress mainly focus on the needs of the market, society and the times for safety, reliability, miniaturization and environmental protection of switchgear. [0003] Continuing to use SF6 as an insulating gas will cause a substantial increase in environmental and social costs in the future. Therefore, reducing, restricting, or even banning SF6 gas in the power system is an inevitable trend in the development of power grid equipment. [0004] With the continuous progress and improvement of breaking and insulation technology, the development of environmentally friend...
