Problems solved by technology

[0002] The prior art insulating gas high-voltage ring network switchgear is mainly composed of a cabinet body, an overcurrent and overload protection circuit breaker, an isolating switch, an operating mechanism and an insulating gas. The cabinet body is provided with a sealed chamber, which is filled with SF 6 High-voltage insulating gas, over-current and overload protection circuit breakers and isolating switches are installed in a sealed room; the problems existing in the prior art insulating gas high-voltage ring network switchgear are: SF 6 Insulation gas is one of the restricted greenhouse gases, and some countries and regions have proposed control measures for the use of this greenhouse gas
but looking for SF 6 When replacing the gas, the electrical performance requirements such as the reliability, safety and operation continuity of the switchgear cannot be sacrificed.

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as Figure 1 to Figure 4 , a modular environment-friendly gas-insulated ring network cabinet, including a cabinet body 1, which is divided into an upper secondary power distribution chamber 2, a middle gas box 3, an operating mechanism chamber 4, and a lower cable chamber 6 and a pressure relief chamber 5. The air box 3 is a closed structure and is filled with nitrogen gas in the air box.

[0019] The air box 3 is equipped with a bracket 7, an ABC three-phase circuit transmission mechanism 8, an ABC vacuum interrupter 9 and an ABC three-position isolating switch 10. One end of the ABC three-position isolating switch is fixed on the inner wall of the air box, and the other end is fixed On the bracket, the transmission mechanism of phase A is connected with the vacuum interrupter of phase A, the other end of the interrupter of phase ...

Abstract

The invention relates to a modular environment-friendly gas-insulated ring network cabinet, which comprises a cabinet body, wherein the cabinet body is provided with a closed gas tank and the gas tank is filled with nitrogen; three-phase circuit transmission mechanisms, three vacuum arc-extinguishing chambers and three-position isolation switches are sequentially arranged in the gas tank from top to bottom; a bracket is also arranged in the gas tank; one end of each of the three-position isolation switches is connected to the bracket and the other end is connected to the inner wall of the gas tank; the three vacuum arc-extinguishing chambers correspond to the three-phase circuit transmission mechanisms; and the vacuum arc-extinguishing chambers are connected with the three-phase circuit transmission mechanisms and the three-position isolation switches respectively. The modular environment-friendly gas-insulated ring network cabinet has the characteristics of being green and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinet equipment, in particular to a modular environment-friendly gas-insulated ring network cabinet. Background technique [0002] The prior art insulating gas high-voltage ring network switchgear is mainly composed of a cabinet body, an overcurrent and overload protection circuit breaker, an isolating switch, an operating mechanism and an insulating gas. The cabinet body is provided with a sealed chamber, which is filled with SF 6 High-voltage insulating gas, over-current and overload protection circuit breakers and isolating switches are installed in a sealed room; the problems existing in the prior art insulating gas high-voltage ring network switchgear are: SF 6 Insulation gas is one of the restricted greenhouse gases, and some countries and regions have proposed control measures for the use of this greenhouse gas. For example, the Clean Energy Future Plan launched by Australia h...
