Problems solved by technology

[0004] At present, the body structure of the sulfur hexafluoride switch is often connected with a wiring device to measure the opening and closing time of the switch, but the design of the existing wiring device is relatively complicated and the installation is inconvenient
[0005] On the other hand, the sealing plate on the existing body structure is generally made of No. 45 steel. During long-term use, it is prone to rust and wear due to oxidation and scratching, which affects the service life

Abstract

The invention relates to an SF6 switch detection sealing plate, comprising: a sealing plate body, the sealing plate is a cylindrical disc, a cylindrical groove is opened at the central point of the sealing plate, and multiple sets of wiring terminals are arranged in the cylindrical groove. 240 operates the characteristics of the front side mechanism, and the middle one is the CT terminal, which is used to measure the opening and closing time of the switch. Ensure that the three phases are synchronized to prevent internal parts from being damaged due to excessive operating work after the mechanism is assembled. At the same time, the application also coats a layer of protective paint on the outside of the SF6 switch detection sealing plate, which effectively improves the corrosion resistance and impact resistance of the SF6 switch detection sealing plate, and prolongs the service life of the SF6 switch detection sealing plate.

Description

technical field [0001] The invention belongs to the field of SF6 switches, and in particular relates to an SF6 switch detection sealing plate. Background technique [0002] Sulfur hexafluoride SF6 switch is a new switch using sulfur hexafluoride gas as insulating medium and arc extinguishing medium. Sulfur hexafluoride gas is a colorless, odorless, non-toxic, non-flammable inert gas with high electrical strength and good arc extinguishing performance, and its dielectric strength far exceeds that of traditional insulating gases. Therefore, its use in electrical equipment can reduce the size of equipment, eliminate fires, and improve the reliability and safety of power systems. [0003] The sulfur hexafluoride switch is composed of three parts: the body structure (three boxes in one box), the operating mechanism, and the arc extinguishing device. It has the advantages of simple structure, small size, light weight, large breaking capacity, rapid arc extinguishing, many times ...
