Description

Technical Field

[0001] The invention belongs to the technical field of switch cabinet discharge detection, and in particular relates to a switch cabinet partial discharge rapid detection device. Background Art

[0002] Partial discharge test refers to a test mode that obtains discharge signals when partial discharge occurs in the equipment. The current mainstream switch cabinet live testers are divided into two types: ordinary handheld terminals and positioning machines. Among them, ordinary handheld terminals are mainly used for daily general testing. Generally, non-contact ultrasonic sensors are used to detect all the gaps in the switch cabinet. After frequency synchronization, the characteristics of the collected ultrasonic signals are presented in several modes such as time domain, phase, flight, and waveform to assist the detection personnel in distinguishing the signals. The amplitude method can be used to roughly locate the signal source. The disadvantage is that the ultrasonic signal attenuates greatly during propagation, and the detection personnel need to get close to all the gaps for detection one by one, which is time-consuming and labor-intensive, and the positioning effect can be almost ignored. The positioning machine is used to accurately locate abnormal signals. Generally, a high-speed oscilloscope is used to calculate and realize positioning by using the time difference of the signal arriving at different channels. There are mainly ultra-high frequency time difference method and acoustic-electric combined method, but its operation is complicated and the positioning effect is not good in application scenarios where equipment such as switch cabinets are compactly arranged.
