Description
Technical field
The present invention relates to a kind of bypass drainage devices, and in particular to on-load replaces fuse switch bypass drainage dress
It sets.
Background technique
Currently, when carrying out on-load replacement fuse switch operation, it is necessary first to which livewire work personnel carry out necessary
Then insulation masking measure is shorted the upper and lower pile crown and its lead of fuse using the bypass of livewire work special isolation drainage thread,
It is finished to change of fuse, after detection is through-flow normally, then removes insulation lead wire and restore to operate normally.Since conventional insulator draws
Streamline line footpath is larger, length is longer, it is difficult to be reliably fixed, be easy to cause to slide because of swing, cause route or equipment to stop transport, therefore
Need to carry out masking of insulating on a large scale.In addition, the upper and lower pile crown connecting lead wire of fuse is aerial insulated wire, installation bypass
It needs to exploit insulating layer using cutter before insulation lead wire, causes flow chart cumbersome.So using conventional insulator drainage thread band
It is very big that load replaces fuse switch operating risk, and time-consuming for operation, and working efficiency is lower.
Summary of the invention
