A high voltage switch cabinet

Abstract

The present invention relates to a high-voltage switch cabinet. The high-voltage switch cabinet comprises a cabinet body and a charged display sensor arranged in the cabinet body, the cabinet body isinternally provided with a support configured to install the charged display sensor, the high-voltage switch cabinet further comprises a partial discharge sensor having a Rogowski coil, a mounting cavity is arranged between the support and the cabinet body, the partial discharge sensor is installed in the mounting cavity, the partial discharge sensor is provided with a line punching hole configured to allow a signal line of a coupling capacitor of the charged display sensor to pass through, and the partial discharge sensor comprises a signal line configured to lead out the detected partial discharge signals. The high-voltage switch cabinet comprises the cabinet body having the partial discharge sensor having the Rogowski coil, the partial discharge sensor inducts and collects the partial discharge information in the cabinet body and timely transmits the partial discharge information through the signal line to achieve charged measurement of the partial discharge of the high-voltage switch cabinet.

Description

technical field [0001] The invention relates to a high-voltage switch cabinet. Background technique [0002] As society's demand for electricity continues to increase, people's requirements for power quality are getting higher and higher, and the requirements for safe operation of equipment are also increasing accordingly. High-voltage switchgear is a large number of electrical equipment used in distribution networks. In actual operation, periodic inspections of high-voltage switchgear are required, and the workload of operation and maintenance is heavy. [0003] The Chinese patent with the announcement number CN205004669U and the announcement date of 2016.01.27 discloses an intelligent metal-enclosed switchgear. The intelligent metal-enclosed switchgear includes a cabinet and a circuit breaker handcart. The cabinet includes a busbar room, a cable room and In the secondary component room, electric grounding switches, high-voltage live sensors, ambient temperature sensors an...
