Problems solved by technology

Many people are required to cooperate during the test, the locking buckle needs to be adjusted many times, and the position is difficult to grasp
This method is time-consuming and laborious to test GIS micro-water, and the connection between the inflatable joint of the GIS pipe mother and the joint of the tester generally needs to be operated at high altitude, which increases the risk of work at the same time as the test time is long

Embodiment Construction

[0028] The joint fixing device of the SF6 micro-water tester and its use method proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that the drawings are all in a very simplified form and use imprecise ratios, which are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0029] The core idea of ​​the present invention is to provide a SF6 micro-water tester joint fixing device and its use method. The SF6 micro-water tester joint fixing device adopts a method of adding a flange (that is, a support) to compress the tester The joint flange and the inflatable joint flange are designed with a hook and a handle, so that the hook can hook the inflatable joint flange so that the tester joint and the infl...

Abstract

The invention provides a sulfur hexafluoride (SF6) micro water tester joint fixing device and a using method thereof. A tester joint flange and an inflation joint flange are pressed by employing a method for increasing a flange (namely a support), and the design of matching a hook and a handle is used, so that the inflation joint flange can be hooked by the hook, and the tester joint flange and the inflation joint flange are tightly connected. According to the SF6 micro water tester joint fixing device and the using method thereof, the original step of clamping and connecting the flanges by using a wrench or a fastener is simplified, the operation of pressing and connecting the joint can be easily finished without excessive manual labor, the testing time is shortened, and the working risk is reduced.

Description

technical field [0001] The invention relates to the field of GIS safety testing, in particular to a joint fixing device for an SF6 micro-water tester and a use method thereof. Background technique [0002] GIS (GAS INSULATED SWITCHGEAR) is the English abbreviation for gas insulated fully enclosed combined electrical appliances. GIS is composed of circuit breaker, isolating switch, grounding switch, transformer, lightning arrester, pipeline busbar, connector and outlet terminal, etc. These devices or components are all enclosed in a metal grounding shell, and the inside is filled with a certain pressure of SF6 ( Sulfur hexafluoride) insulating gas, so it is also called SF6 fully enclosed combined electrical appliances. GIS equipment has been widely used all over the world since it was put into practical use in the 1960s. GIS is not only widely used in the field of high voltage and ultra-high voltage, but also in the field of ultra-high voltage. Compared with conventional o...
