Abstract

The invention discloses an elevating insulator cross arm for uninterrupted operation of a distribution network and an operation method of using the elevating insulator cross arm. The elevating insulator cross arm comprises a first epoxy resin pipe, a second epoxy resin pipe and a third epoxy resin pipe, wherein the second epoxy resin pipe is fixed at the middle part of the first epoxy resin pipe; and two ends of the third epoxy resin pipe are fixedly connected with the first epoxy resin pipe and the second epoxy resin pipe respectively to form a triangular structure. The elevating insulator cross arm is a special tool for uninterrupted replacement of a straight rod insulator and a cross arm; and the elevating insulator cross arm is high in applicability and light in weight. When straight rod insulator and cross arm uninterrupted replacement operation is carried out, a wire does not need to be shielded and the operation procedure is reduced. The operation method is convenient and simple; the frequency that the live working personnel contact a charged body is reduced; and the security coefficient of live working is improved. The elevating insulator cross arm is used for the uninterrupted operation of the distribution network, the power failure frequency can be reduced, the power failure time can be shortened and the power supply reliability is improved.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of distribution network non-stop operation, and relates to a tool for replacing a 10kV linear rod insulator and a cross arm, in particular to a lifting type insulating cross arm for distribution network non-stop operation and an operation method thereof. [0003] 【Background technique】 [0004] At present, the replacement of 10kV linear rod insulators and cross-arms is carried out without power failure in the distribution network. There is no special replacement tool, which cannot improve work efficiency and reduce the risk factor of live workers. Part of the work that can be repaired with live electricity has become a power outage maintenance, which affects the reliability of the power supply of the distribution line and affects the normal life and production of residents, municipalities and enterprises within the power supply range of the line. [0005] 【Content of invention】 [0006] The purpose ...
