Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] refer to figure 1 , the SF6 equipment micro-water test special joint of the present invention is in the form of a four-way valve and includes four functional areas: pressure display end A, test instrument hose interface end B, check valve end C, and equipment connection port end D. There is a chamber inside the special joint for micro-water testing, the top of the chamber is fixedly connected to the pressure display end A, the bottom is threaded to the check valve end C, and one of the left and right sides is connected to the test instrument hose interface end B , the other side of the left and right sides is connected to the equipment connection port D, the pressure display end A is opposite to the check valve end C, and the test instrument hose interface B is opposite to the equipment connection port D.

[0016] The pressure display terminal A is a pressure...

Abstract

The invention discloses a special connector for SF6 equipment micro water test. The special connector for SF6 equipment micro water test is in a four-way valve type and comprises a pressure display end, a test instrument hose connector end, a check valve end and a device connection port end. The interior of the micro water test special connector is provided with a cavity. The top of the cavity is fixedly connected with the pressure display end. The bottom of the cavity is in threaded connection with the check valve end. The left side or the right side of the cavity is connected with the test instrument hose connector end, and the other side is connected with the device connection port end. The pressure display end is opposite to the check valve end. The test instrument hose connector end is opposite to the device connection port end. The universality of the special connector for SF6 equipment micro water test is achieved, gas pressure can be displayed, a check valve end can be rapidly turned off when a failure happens, and working efficiency and safety performance are improved.

Description

technical field [0001] The invention relates to a special joint device for gas testing, in particular to a special joint device for micro-water testing of SF6 equipment in a substation. Background technique [0002] With the increase of substation GIS equipment, SF6 equipment micro-water testing is becoming more and more important, and the problems caused by the different designs of the joints as its key components become more prominent due to the different designs of different manufacturers. The micro-water test joints of SF6 equipment currently used in the long-term use process have found that the joints have single functions, different shapes, and require multiple splicing during use. Moreover, some GIS equipment does not have a pressure display terminal, and the existing joints cannot meet the requirements. Pressure shows demand. The existing SF6 equipment micro-water test joint not only has a complicated connection process and takes a long time, but also cannot display...
