Abstract

The invention discloses an environment-friendly insulating ring main unit, which comprises a gas tank, an ejection sleeve, an arc extinguishing chamber, an isolation static contact, an operating mechanism, an isolation-grounding switch, a grounding static contact, a lower branch bus, a lower ejection sleeve, a lower ejection sleeve pressing plate and an outer shell, wherein the gas tank is arranged in the outer shell; the gas tank is filled with a heptafluoroisobutyronitrile-air mixed gas; the ejection sleeve penetrates through the upper plane of the gas box and then is connected with the arcextinguishing chamber, and the arc extinguishing chamber is arranged in the gas box; the isolation static contact is connected with the operating mechanism; one end of the isolation-grounding switch is connected with the isolation static contact, and the other end of the isolation-grounding switch is connected with the grounding static contact; and the lower branch bus and the lower ejection sleeve are arranged in the lower ejection sleeve pressing plate, and the operating mechanism is connected with the lower branch bus. According to the environment-friendly insulating ring main unit providedby the invention, the heptafluoroisobutyronitrile-air mixed gas is used as an insulating medium, so that an environment-friendly effect is achieved, and the environment-friendly insulating ring mainunit is small in occupied area.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to an environment-friendly insulating ring network cabinet. Background technique [0002] In the current power supply network system in my country, in order to improve the reliability of power supply, the power supply network is usually connected into a ring, so that users can obtain power from two directions. This power supply method is called ring network power supply. The ring network cabinet is the core switchgear in the ring network power supply equipment. According to the different insulating media, the ring network cabinet is divided into air type ring network cabinet, SF6 gas insulated ring network cabinet, solid insulation ring network cabinet and so on. [0003] The existing gas-insulated ring network cabinet mainly uses sulfur hexafluoride (SF 6 ), SF 6 It is a gas with highly stable chemical properties. It has excellent insulation and arc extinguishing properties and ...
