Problems solved by technology

This has just greatly increased labor man-hours, increased the input of manpower and material resources of the test, reduced work efficiency, and also caused waste of FS6 (sulfur hexafluoride) gas in the tank
[0003] In addition, the manual inspection method judges the location of the discharge through the sound generated by the discharge. When the discharge sound is transmitted in the GIS tank, the entire busbar will have a discharge sound, which is very prone to human misjudgment, and it is difficult to judge the discharge location very accurately. Air chamber, which greatly affects the test efficiency and project progress

Abstract

The invention relates to a discharge failure locating apparatus, a locating system and a locating method. The discharge failure locating apparatus comprises a power supply, a shock sensor, a trigger and an alarm; wherein, the shock sensor is used for detecting shocl signals and converting the detected shock signals into electrical signals; the trigger is used for receiving the electrical signals from the shock sensor and switching on an alarm loop; the alarm is used for sending out alarm signals after the alarm loop is switched on; the power supply is used for providing power for the shock sensor, trigger and alarm. The alarm belongs to at least one kind of sounding components, lighting components and wireless signal emission components. The discharge failure locating apparatus adapts to the indetermination of site environment to accurately find the failure with the advantages of high reliability and stable capability.

Description

technical field [0001] The invention relates to a fault location technology in the field of electrical detection, in particular to a discharge fault location device, a location system and a location method used in the withstand voltage test of combined electric or tank-type electric equipment. Background technique [0002] In the power transmission and transformation system, the AC withstand voltage test is the most important means to check whether the insulation of primary power equipment is good. In the withstand voltage test of GIS (combined electrical) and tank circuit breaker, due to poor insulation in the gas chamber or impurities in the gas chamber, discharge breakdown will occur during the withstand voltage test, accompanied by sound and tank vibration. Due to the large number of gas chambers in the equipment for the withstand voltage test, it is difficult to accurately determine the gas chamber where the discharge occurs based on the discharge sound and experience a...
