Description
Technical field
The present invention relates to a kind of insulated shielding cover being applied to the charged spliced cables lead-in wire of 10kV.
Background technology
Construction and development along with overhead distribution, current 10kV distribution line live working has become as and ensures power grid security reliability service, minimizing energy loss and a uninterrupted important means to customer power supply and raising electrical network economy benefit, and electrically mated the tearing open of line (leap) cable tail tape takes workload in ascendant trend year by year. Need for this to use the shading tool that insulate accordingly, a series of maintenance installation exercise could be completed in safely and effectively situation. This also becomes avoids power failure operation to cause the effective way of unnecessary loss on 10kV overhead distribution equipment. Current 10kV urban power distribution network continues to optimize raising, and than 110kV and above power transmission network, 10kV overhead distribution has following characteristics:
(1) line arrangement mode is compact. Common horizontally arranged for double loop, also have quite a few horizontally arranged for multiloop and rounded projections arranged combines and is erected on same supplying channels.
(2) line span difference is big, and scissors crossing is many. Urban line span mostly is 40m～50m, is 20m～30m individually, and the distribution network line in more remote periphery small towns reaches about 60m a bit, and many crossings are crossed over to adopt and connected without supporting.
YH5W-17/50 composite jacket gaspless metal oxide arrester (hereinafter referred to as spark gap) commonly uses in 10kV distribution line, due to 10kV and following electricity distribution power equipment relatively, alternate design pitch little, carrying out of power distribution live-wire is caused difficulty and restriction.
