Description

Technical Field

[0001] The utility model belongs to the field of wireless communication, specifically a sensor, and relates to a multi-modal three-in-one partial discharge sensor. Background Technique

[0002] The multi-modal three-in-one partial discharge sensor is designed with a fully digital front-end sensor. From the antenna, filtering, amplification, detection, ADC digital-to-analog conversion to local signal processing, all are completed within the sensor. The sensor simultaneously collects partial discharge ultrasonic, TEV, and UHF signals, and can be used for on-line monitoring of partial discharge in high-voltage switch cabinets. When the multi-modal three-in-one partial discharge sensor is used, it needs to be installed on the side wall of the switch cabinet to prevent it from detaching from the switch cabinet.

[0003] The installation method of the multi-modal three-in-one partial discharge sensor on the side wall of the switch cabinet varies depending on the type of the switch cabinet and the allowable power-off installation conditions. Each switch cabinet is equipped with one multi-modal three-in-one partial discharge sensor, and there are two installation methods: magnetic attraction and industrial adhesive. Through the magnet installed inside the multi-modal three-in-one partial discharge sensor, the sensor can be adsorbed on the side wall of the switch cabinet, and by using epoxy resin glue, the sensor can be fixed on the side wall of the switch cabinet.

[0004] Using the above installation method with industrial adhesive, the multi-modal three-in-one partial discharge sensor is directly fixed to the switch cabinet with glue. When maintenance of the multi-modal three-in-one partial discharge sensor is required, it is prone to the problem that the sensor is inconvenient to disassemble. When using the above magnetic attraction installation method, due to the self-gravity of the multi-modal three-in-one partial discharge sensor, the magnetic attraction will slide down after long-term use, and it is easy to cause the problem that the multi-modal three-in-one partial discharge sensor slides down and falls off.

[0005] In view of this, the present utility model is specifically proposed. Content of the Utility Model
