The invention relates to an insulating cover applicable to a switch on a 10kV distributing line post. The insulating cover comprises a body, wherein the body is provided with an insulating layer and a thermal insulating layer, a raised part is arranged at the top end of the body, the bottom of the body is provided with a circular truncated cone shaped connecting part and the connecting part is smaller in upper part and larger in lower part; the body is provided with a testing hole and cooling holes, and a fixing component is arranged at the bottom end of the connecting part. The insulating cover provided by the invention has the advantages that the body sleeves a pile head of the switch through the connecting part, therefore, the short circuit and trip phenomenon caused by direct falling of existing foreign matters including twigs or iron wires and others on the pile head of the switch on the post can be solved, and the short circuit and trip times of a distributing line due to birds troubles or small animals can be reduced so that the power supply reliability is improved; furthermore, a user can be powered persistently, and the economic benefit can be improved; in addition, the infrared temperature measurement work on the switch can be carried out by the testing hole formed in the body and the heat quantity generated by the switch can be cooled and discharged by the cooling holes formed in the body, therefore, the heating problem of connecting points on the pile head of the switch can be processed in time.
Description
technical field [0001] The invention relates to an insulating cover suitable for switches on poles of 10kV power distribution lines. Background technique [0002] Birds often nest on the crossarm of the 10kV distribution line, which often causes the line to trip due to short circuit caused by tree branches or wires falling on the switch pile head, which brings great hidden dangers to the normal operation of the distribution line and increases the work of operation and maintenance personnel. It is impossible to supply power to residential users normally, which will easily cause dissatisfaction and complaints from users, and affect the production and electricity consumption of enterprises. Because the previous fully enclosed type cannot check whether the switch connection points are in good contact, and cannot carry out infrared detection work, some switch pile heads are due to poor contact. And burn out failure power failure. Contents of the invention [0003] The technica...
