Problems solved by technology

During the operation of GIS equipment, when GIS component 1 needs to be opened for maintenance or air leakage occurs, the gas inside GIS component 2 flows to GIS component 1 through the air holes on the supporting insulator, causing the leakage area to expand
[0005] In summary, when supporting insulators are used, the leakage area cannot be reduced when the GIS components are opened for maintenance or air leakage occurs, which makes maintenance or emergency repair difficult and makes the equipment power outage longer

Embodiment Construction

[0036] In view of this, the core of the present invention is to disclose a GIS insulator, which reduces the leakage area. Another core of the present invention is to disclose a GIS with the above insulator.

[0037] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] like Figure 1-Figure 6 As shown, the present invention discloses a GIS insulator, which includes: an insulator body and a control valve, wherein the insulator body has an air hole channel 11 for gas flow; and the control valve is used to control the opening and closing of the air hole channel 11 . When the control valve controls the air hole channel 11 to open, the insulator body is in a conduction state, and the gas in the components in the same air chamber can be connected; when the control valve controls the air hol...

Abstract

The invention discloses a GIS and an insulator thereof. The insulator comprises an insulator body with a gas hole channel (11) for gas circulation, and a control valve which is arranged in the gas hole channel (11) and is used for controlling the opening and closing of the gas hole channel (11). When the control valve controls the gas hole channel (11) to be opened, the insulator body is in a conducting state. When the control valve controls the gas hole channel (11) to be closed, the insulator body is in a separated state. During working, the insulators are adjusted according to requirements to realize interchange between ventilation and non-ventilation. Specifically, when one of the elements in the same gas chamber needs to be depressurized or maintained, the gas hole channel can be closed to enable the insulator body to be in a separated state, at the moment, other elements are not affected, the elements needing to be depressurized or maintained can be independently released, the leakage area is greatly reduced, the GIS butt joint workload is reduced, and the power failure time of equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of electrical components, in particular to a GIS and an insulator thereof. Background technique [0002] Gas-insulated metal-enclosed switchgear, referred to as GIS, is a complete set of combined electrical appliances using SF6 gas as insulation and arc extinguishing medium. It mainly includes high-voltage electrical components such as circuit breakers, isolating and grounding combination switches, fast grounding switches, current transformers, voltage transformers, lightning arresters, inlet and outlet bushings or cable terminals. It can be used in various power plants and substations in AC power systems of different voltage levels. Because the equipment has the characteristics of small footprint, less space, no influence of external environmental conditions, no noise and radio interference, safe and reliable operation, and less maintenance workload, it is especially suitable for urban substations and ente...
