How to deal with the heating of the high-voltage cable branch box

When the high-voltage cable branch box heats up, it is controlled according to certain methods and methods to ensure that it will not be affected to a certain extent in the actual treatment, and affect the operation and value in actual use; first, perform temperature monitoring, according to the heating temperature and The speed of development determines whether it is necessary to apply to the dispatcher to change the operation mode or reduce the load, and change the operation mode; the second is to repair the isolation switch, generally replace the static contact spring clamp and burn contact fingers, remove the oxide layer of the dynamic and static contacts, and clean the dynamic and static contacts. Apply conductive glue and tighten the bolts. The thorough method is to replace the static contact.

The high-voltage cable branch box has been in operation for a long time, the equipment tends to be aging, the characteristics of the static contact finger compression spring are deteriorated, or the static contact finger is in unilateral contact, the contact clamping spring is loose and deformed, and the clamping force is not enough to cause part of the contact finger to move. The contacts are not in contact, and heat is frequent when the peak summer load is large; therefore, regular maintenance of the high-voltage cable branch box is the main way to reduce the occurrence of product failures.
