Partial discharge two-in-one intelligent sensor

Abstract

The invention relates to the field of sensors, and particularly discloses a partial discharge two-in-one intelligent sensor, which comprises a protective shell and a two-in-one detection mechanism installed in the protective shell. A sealing cover is arranged at the top end of the protective shell. The two-in-one detection mechanism is sleeved with an integrated positioning installation box with an upward opening, and the two-in-one detection mechanism is poured in the positioning installation box through an insulating material. Positioning sliding rods are arranged at the corners of the periphery of the lower surface of the positioning installation box, the bottoms of the positioning sliding rods are fixedly connected with the bottom of the protective shell, and the bottoms of the positioning sliding rods are sleeved with damping springs. A first sliding groove allowing the positioning sliding rod to slide up and down is formed in the position, corresponding to the positioning slidingrod, of the positioning installation box. Sliding blocks of a T-shaped structure are installed on the side walls of the periphery of the positioning installation box. When the intelligent sensor is overhauled, the intelligent sensor can be stably taken out by hand only by reversely rotating the screw rod by hand.

[0002] Switchgear is often used to place primary power equipment. If there is partial discharge in the primary power equipment in the switchgear and it is not discovered in time, it may lead to failure of the primary power equipment, thereby affecting the stability and reliability of the grid operation. influences

The measurement data of partial discharge on-line monitoring is one of the important indicators for judging the operating conditions of power primary equipment. Usually, partial discharge sensors are used to carry out online monitoring of partial discharge of power primary equipment. The existing transient ground voltage / ultrasonic combination An intelligent sensor has both ultrasonic detection and transient ground voltage detection functions. The sensor is installed inside the device. During the long-term use of the sensor, when the sensor is damaged inside, the sensor will fail. At this time, the sensor needs to be disassembled and repaired. For detection and maintenance, but due to the complex structure of the sensor installation, it is difficult to disassemble, take out and install again, and the installation structure needs to be improved
