Abstract

The invention discloses a switch cabinet partial discharge on-line monitoring system, which comprises a monitoring host, an RS485 bus, a wireless data receiving terminal, a LoRa wireless transmission module, an acquisition node and a discharge monitoring data acquisition device; the acquisition node is arranged in a switch cabinet, and the discharge monitoring data acquisition device is arranged in the switch cabinet; the LoRa wireless transmission module is arranged on the discharge monitoring data acquisition device, the LoRa wireless transmission module is in wireless connection with the wireless data receiving terminal, and the wireless data receiving terminal and the acquisition nodes are in one-to-many connection. The invention belongs to the technical field of power switch cabinet operation maintenance equipment, and particularly provides a switch cabinet partial discharge on-line monitoring system, which takes ultrahigh frequency and ultrasonic waves as detection indexes and receives ultrahigh frequency electromagnetic waves and ultrasonic waves radiated in a partial discharge process through an antenna sensor and an ultrasonic probe so as to realize partial discharge detection.

Description

technical field [0001] The invention belongs to the technical field of operation and maintenance equipment for electric switch cabinets, and specifically refers to an on-line partial discharge monitoring system for switch cabinets. Background technique [0002] The switch cabinet is an important part of the smart grid. It is mainly used for on-off, control or protection of the power system in power generation, transmission, distribution, power conversion and consumption. The voltage level is 3.6kV ~ 550kV, and its operation stability It directly affects the safe operation of the power grid. The switchgear works in a high-voltage environment for a long time. The insulating material will deteriorate under the action of the electric field, and there will be energy loss. It will also break down under the action of a strong electric field. normal operation. Insulation faults manifest as flashover breakdown of outer insulation to ground, flashover breakdown of inner insulation t...
