Problems solved by technology

SF6 is a greenhouse gas. It will decompose and produce toxic gas after the arc is broken. It cannot be recycled after the product life ends. The SF6 inflatable cabinet is not conducive to environmental protection; the above three cabinet types currently have a single parameter in the market and are fixed. Type installation is not convenient for maintenance

Abstract

The invention provides a drawer type air insulated ring network cabinet which is characterized in that a protective plate, through-wall buses with static contacts, switch units, current transformers, sensors and lightning arresters are installed on a cabinet body, main buses and disconnecting switch static contacts are installed on the through-wall buses with the static contacts, one end of each switch connection bar is connected with the vacuum arc-extinguishing chamber moving end line outgoing base on the switch units, the other end of each switch connection bar is connected with the current transformers, and the current transformers and the sensors are connected by copper bars. Advantages are that the switch cabinet is simple in structure and high-parameter, and the switch units can be drawer type switch units so that product maintenance is facilitated; and no harmful gas is generated, and all the parts and components can be recycled after reaching the service life so that environmental protection property of the product can be greatly enhanced, and the drawer type air insulated ring network cabinet can be suitable for the requirements of environmental protection.

Description

technical field [0001] The invention is a novel withdrawable air-insulated ring network cabinet. The utility model belongs to the technical field of high-voltage switchgear equipment. technical background [0002] At present, the ring network cabinets on the market use SF6 inflatable cabinets, solid insulation cabinets, dry air and N2 inflatable cabinets. SF6 is a greenhouse gas. It will decompose and produce toxic gas after the arc is broken. It cannot be recycled after the product life ends. The SF6 inflatable cabinet is not conducive to environmental protection; the above three cabinet types currently have a single parameter in the market and are fixed. Type installation is not convenient for maintenance. Contents of the invention [0003] The present invention proposes a new withdrawable air-insulated ring network cabinet, which aims to overcome the above-mentioned defects in the prior art, and has the advantages of small size, environmental protection, integrated fu...
