Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical distribution cabinet maintenance technology, and in particular to a maintenance device for high and low voltage electrical distribution cabinets. Background Technology
[0002] High and low voltage switchgear are power distribution equipment used in power supply systems for power distribution, control, metering, and cable connection. For the safety of high and low voltage switchgear, regular maintenance is often required. When maintaining high and low voltage switchgear, it is usually necessary to use a voltage detector to check whether the circuit is energized to ensure that maintenance is carried out under safe conditions.
[0003] Currently, when performing power outage maintenance on high and low voltage distribution cabinets, the power is usually disconnected beforehand, and then a voltage detector is used to check whether the high and low voltage distribution cabinets are properly disconnected, thus ensuring that the high and low voltage distribution cabinets can be safely disconnected for maintenance. The insulating rod of this voltage detector is usually a telescopic structure. If the rod is not fully extended, it is easy for it to suddenly retract due to gravity during the maintenance of the distribution cabinet. If the rod is pulled out too much, it is not easy to retract the telescopic rod. Using this type of voltage detector with a telescopic insulating rod is inconvenient and not conducive to the maintenance operation of high and low voltage distribution cabinets. Therefore, we propose a maintenance device for high and low voltage distribution cabinets. Utility Model Content
