TEV-based switch cabinet partial discharge detection system

The invention provides a TEV-based switch cabinet partial discharge detection system which comprises monitoring terminals, a wireless repeater and a monitoring computer. The monitoring terminals are mounted on the outer surfaces of switch cabinets. The wireless repeater is a Zigbee wireless receiving repeater and used for receiving data of all the monitoring terminals in a station and sending the data to a monitoring computer. The monitoring computer is a background processing computer. The TEV-based switch cabinet partial discharge detection system has the advantages that it can be seen from the field testing result, compared with an EA company product, the system can measure the particle discharge in the switch cabinets more accurately and distinguish the fault switch cabinet obviously, and it is tested that the system has higher field detection capacity.
