Insulation testing device and method for 6/10kV switch cabinet with five-prevention function

Abstract

The invention discloses an insulation testing device and method for a 6 / 10kV switch cabinet with a five-prevention function. The device comprises a transmission chassis truck, a conductive contact stand and an electromagnetic mechanical locking mechanism. The transmission chassis truck comprises a chassis trolley and a bearing tray, the conductive contact stand comprises an insulating strut, a core-piercing insulating cylinder, a conductive copper pipe, a plum blossom button contact and a conductive copper plate, the electromagnetic mechanical locking mechanism comprises an electromagnetic relay and a mechanical locking mechanism, after the electromagnetic relay is energized, an electromagnetic coil carries out attraction, the mechanical locking mechanism opens the lock between the chassistrolley and the bearing tray, the chassis trolley enters a switch chamber of the switch cabinet after deviating from the locking of the bearing tray, the conductive copper pipe and the plum blossom button contact are electrically connected with a tested insulating load device, and the insulation testing device is connected with the conductive copper plate in the core-piercing insulating cylinderto perform insulation testing treatment. The insulation testing difficulty of onsite operation and maintenance personnel and high safety risks are effectively solved.

Description

Technical field [0001] The invention relates to a device and a method for measuring insulation of a 6 / 10kV switch cabinet with five defense functions. Background technique [0002] Nowadays, with the development of society, in order to optimize the power supply and distribution methods of various industrial enterprises, many users use 6 / 10kV switch cabinets to supply power to related equipment. The relatively high voltage power supply method can effectively avoid low voltage and high current equipment. The shortcomings of difficulty in manufacturing, easy heating, large installation space, and high comprehensive cost provide conditions for various users in load distribution. However, the high-voltage power supply method is to verify whether various electrical load equipment is in good condition before being put into operation. , The insulation measurement of electrical equipment (hereinafter referred to as insulation measurement) is the most effective, very important, and most di...

AI Technical Summary

Problems solved by technology

This method of insulation measurement not only increases the maintenance workload of the enterprise's operation and maintenance personnel, but also easily causes electric shock events. After the measurement is completed, there is still a need to resume work, which cannot fundamentally solve the problem of equipment recovery. The question of whether the measured equipment is ultimately insulated
