Abstract

The invention relates to the technical field of medium-voltage switchgear, in particular to a medium-voltage switchgear with a fault detection function. By setting a fault detection mechanism, the driving mechanism drives the gear to rotate, thereby driving the slider to move along the track, and passing the metering mechanism Control the moving distance so that the slider can move according to the set distance. By setting up the lifting mechanism and the positioning mechanism, the temperature measuring part is driven up and down, and the lifting position is controlled so that the temperature measuring part can move to the corresponding temperature measuring point. place, accurately measure the temperature of the switchgear, and reset the set value of the metering mechanism through the positioning piece, so that the drive mechanism can drive the slider to continue to move to the next switchgear on the path, thereby continuing to control the next switchgear. The temperature of the temperature measuring point of the switchgear is measured, and the medium voltage switchgear can reduce the manpower invested in equipment inspection, and has a good effect on improving the safety of the switchgear.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of medium-voltage switchgear, and in particular to a medium-voltage switchgear with a fault detection function. Background technique [0002] Medium-voltage switchgear is used in factories, substations, residential quarters, etc., and is mainly used for switching and controlling equipment for power generation, transmission, power supply and distribution, etc. Circuit breakers, isolating switches, etc. are generally installed inside the medium-voltage switchgear A variety of switchgear, in order to ensure the normal and safe operation of the medium-voltage switchgear, it is necessary to frequently carry out fault detection on the medium-voltage switchgear, because there are many internal switchgears, and the main reasons for the failure of the switchgear are poor contact, contact burning Adhesion, etc., these faults will lead to abnormal temperature at the contacts of the switch...
