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

Embodiment 1

[0023] Such as figure 1 As shown, the drop-out fuse bypass drainage device with load replacement of the present invention includes an insulating bushing bracket and an insulating drain wire 1 sleeved inside the insulating bushing bracket, and the insulating bushing bracket includes a vertically arranged vertical rod 2. The lower end of the vertical rod 2 is vertically connected with the lower rod 3, and the upper end of the vertical rod 2 is vertically connected with the upper rod 4 which is set at an angle of 135° with the vertical rod 3. The vertical rod 2, the lower rod 3 and the upper rod 4 are all The hollow structure is connected with each other, the middle part of the vertical bar 2 is vertically connected with the horizontal bar 5, and the end of the horizontal bar 5 far away from the vertical bar 2 is connected with the cross-arm fixing hook 6, and the cross-arm fixing hook is provided with locking bolts , the insulated drain wire 1 passes through the upper rod 4, the...

Embodiment 2

[0027] Such as figure 1 As shown, the bypass drainage device for drop-out fuse with load replacement in the present invention, on the basis of Embodiment 1, the vertical rod and the lower rod are connected by a 90° joint 7 and a locking screw cap, and the vertical rod and the upper rod are connected. A 45° joint 8 and a locking screw cover are used to connect, and a plum blossom joint 9 is used to connect the side wall of the vertical bar and the end of the cross bar.

[0028] That is, the three connection points on the vertical bar adopt three joint points that can realize rotation (respectively 90° joint, 45° joint, and plum blossom joint), so that the upper bar, the horizontal bar and the lower bar can be rotated by rotating these three joint points. The rod realizes 360°rotation adjustment, so as to obtain enough working space and operation path, which is suitable for various job sites with complicated layout of electrical equipment on the rod; at the same time, the multi-...

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...
