Problems solved by technology

The open circuit breaker generally adopts an outdoor porcelain sleeve structure and is installed at a high position. It requires the operator to hold the sensor for a long time to detect, which is easy to make the operator tired and deformed, which will lead to inaccurate test results and increase the workload. Dangerous, unable to meet the needs of actual use, and currently it is impossible to obtain the detection results of partial discharge intuitively at the detection site during operation

Abstract

The invention provides an open-type circuit breaker partial discharge detection device based on acoustoelectric combination, which comprises a driving device and an acoustoelectric combination detection mechanism, and is characterized in that the driving device is used for driving the acoustoelectric combination detection mechanism to ascend and descend; the acoustoelectric joint detection mechanism comprises a Y-shaped metal rod, and an ultrasonic wave induction device, an electromagnetic induction box, electrochromic glass and a light source which are arranged in the box body, the ultrasonic wave induction device and the electromagnetic induction box are provided with electric output ends, and the electric output ends are electrically connected with the electric amplification module; the output end of the electric amplification module is connected with the electrochromic glass, a display cavity is formed in the box body, a shell at the display cavity is made of transparent glass, the electrochromic glass is fixed in the display cavity, the light source is fixed under the electrochromic glass, a smoke generator is arranged on one side of the display cavity, and the smoke generator is arranged on the other side of the display cavity. The outlet end of the smoke generator is connected with the interior of the display cavity.

Description

technical field [0001] The invention relates to the technical field of partial discharge fault detection of circuit breakers, in particular to an open circuit breaker partial discharge detection device based on the combination of sound and electricity. Background technique [0002] The existing partial discharge detection methods can be used for reference in principle, but in practical applications, the field detection conditions and the safety of equipment and personnel should be considered. At present, in the process of partial discharge live detection in GIS or switchgear, because these devices have metal grounded boxes, sensors can be used to contact devices to obtain internal discharge information. The open circuit breaker generally adopts the outdoor porcelain sleeve structure and the installation position is high. It requires the operator to hold the sensor for a long time for detection, which is easy to make the operator fatigue and deform the action, resulting in in...
