Abstract

The invention relates to an insulation tube type bus partial discharge detecting device which is mainly characterized by comprising a PC mainframe, a touch screen display, an ultrahigh frequency sensor, an ultrasonic sensor and a power frequency current sensor. The PC mainframe is connected with the touch screen display. A filter amplifying unit, a high-speed data collecting card and partial discharge analyzing software are mounted in the PC mainframe. The ultrahigh frequency sensor, the ultrasonic sensor and the power frequency current sensor are connected to the input end of the filter amplifying unit. The output end of the filter amplifying unit is connected with the high-speed data collecting card. The insulation tube type bus partial discharge detecting device has the advantages that partial discharge signals are picked through the ultrahigh frequency sensor and the ultrasonic sensor, effective evaluation can be performed on the insulation degradation degree of an insulation tube type bus, safety problems caused by the defects of the insulation tube type bus are solved, and safety operation of a power supply system is guaranteed; the device is friendly in interface, clean and visual in information display, convenient to operate, and the like.

Description

technical field [0001] The invention belongs to the technical field of partial discharge detection, in particular to a partial discharge detection device for an insulating tubular busbar. Background technique [0002] With the increasingly widespread application of insulating tubular busbars, the research on its detection technology becomes more important. Because the insulating tubular bus has the advantages of large carrying capacity, good insulation performance, high mechanical strength, good heat dissipation, low temperature rise, anti-interference, long life, etc., many power supply companies are increasingly using insulating tubular bus as the main Transform the connecting conductor between the medium and low voltage side and the power distribution facilities to improve the effective utilization of the bus material, enhance the mechanical strength of the bus, prevent the person from touching the live bus, metal objects falling on the bus and cause phase-to-phase short ...
