Load change drop fuse bypass drainage device

Abstract

A load-changing drop fuse bypass drainage device comprises an insulating sleeve bracket and an insulating drain wire sleeved inside the insulating sleeve bracket, the insulating sleeve bracket comprises vertical rods arranged vertically, a lower bar is vertically connected to the lower end of the vertical bar, the upper end of the vertical bar is vertically connected with an upper bar arranged atan included angle of 135 DEG with the vertical bar, a cross bar is vertically connected to the middle of the vertical bar, a cross bar fixing hook is connected to the end of the cross bar far away from the vertical bar, a locking bolt is arranged on the cross bar fixing hook, and the insulating drainage wire respectively passes through the upper bar, the vertical bar and the lower bar of the insulating sleeve support in a winding manner, and two ends of the insulating drainage wire are connected with a puncture wire clamp. The bypass drainage device of the invention places the insulated drainage wire inside the insulated sleeve to form double insulation protection, avoids a large amount of insulation shielding to the adjacent electrified body or the grounding body in the operation process,reduces the operation time consumption and also reduces the labor intensity of the operator.

Description

technical field [0001] The invention relates to a bypass drainage device, in particular to a bypass drainage device for replacing a drop-out fuse with load. Background technique [0002] At present, when carrying out the operation of replacing the drop-out fuse with load, firstly, the live workers need to take the necessary insulation and shielding measures, and then use the special insulated drain wire for live work to bypass the upper and lower pile heads and their leads of the fuse. After the fuse has been replaced and the flow is detected to be normal, remove the insulated drain wire and resume normal operation. Due to the large diameter and long length of the traditional insulated drain wire, it is difficult to fix it reliably, and it is easy to slip due to swinging, causing the line or equipment to stop running. Therefore, a large-scale insulation shielding is required. In addition, the lead wires connecting the upper and lower pile heads of the fuse are overhead insu...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the traditional insulated drain wire has a large diameter and a long length, which is difficult to be fixed reliably, and is easy to slip due to swinging, causing the line or equipment to be out of service. The operation risk is very large, and the operation takes a long time and the work efficiency Low, the purpose is to provide on-load replacement drop-out fuse bypass drainage device, which has the advantages of reliable connection and fixation, simplified operation procedures, reduced operation risks, reduced time-consuming operation, and improved work efficiency
