Problems solved by technology

However, during daily defect elimination and routine tests, the maintenance personnel found that due to the small space in the cable room of the inflatable cabinet, the touchable pluggable cable elbow (hereinafter referred to as the elbow) due to poor operating environment, long operating time, silicone grease The reason for the poor quality is that the elbow-shaped head is stuck to the conical insulating support porcelain bottle of the cabinet, and it is extremely difficult to remove. Most of the elbow-shaped heads are scratched with a knife, and only a small part can be removed. During the removal process, in order to save time Every elbow removal completely destroys the elbow, and this "cable elbow" is expensive to buy
[0004] Some of the existing disassembly tools have complex structures; some are bulky, which makes it inconvenient to disassemble in a small space; , and time-consuming and laborious, the disassembly effect is not good

Embodiment 1

[0036] This embodiment discloses a plug-in cable elbow remover, such as figure 1 , figure 2 with image 3 As shown, it includes a force application bracket 1, a positioning screw 2, and a hoop 3. The lower part of the force application bracket 1 is provided with a hoop 3 for holding the cable elbow, and the hoop 3 includes a first arc hoop body 31 and a second arc-shaped hoop body 32, the two ends of the first arc-shaped hoop body 31 are detachably connected with the two ends of the second arc-shaped hoop body 32, and the force-applying bracket 1 and the The positioning screw 2 is screwed together, and the positioning screw 2 can reciprocate along the axial direction of the hoop 3 . When removing the plug-in cable elbow, use the hoop 3 to hold the elbow firmly, and rotate the positioning screw 2 to move the positioning screw 2 in the direction of the hoop 3 until the positioning screw 2 touches the conductive rod and continues to rotate The positioning screw 2 squeezes the...

Embodiment 2

[0053] This embodiment discloses a plug-in cable elbow remover, such as Figure 4 or Figure 5 shown.

[0054] The difference between this embodiment and embodiment 1 is that the hoop 3 is hinged to the force applying bracket 1 .

[0055] The first arc-shaped hoop body 31 of the hoop 3 is hinged on the first vertical bar 12, and the second arc-shaped hoop body 32 of the hoop 3 is hinged on the second vertical bar 13 in a two-degree-of-freedom manner. Hinged, that is, the first arc-shaped hoop 31 and the second arc-shaped hoop 32 can rotate inside the force-applying bracket 1 around the hinge with the force-applying bracket 1 in the plane where the force-applying bracket 1 is located.

[0056] Specifically, you can press Figure 4 As shown, the first vertical bar 12 and the second vertical bar 13 are respectively provided with a first connecting plate 16 and a second connecting plate 17 . The first arc-shaped hoop body 31 of the hoop 3 is provided with a first connecting gr...

Abstract

The invention discloses a plug-in cable elbow type head detacher. The plug-in cable elbow type head detacher comprises a force application support, wherein a hoop for hoping a cable elbow type head isarranged at the lower part of the force application support; and a positioning screw capable of reciprocating motion along the axial direction of the hoop is arranged on the top of the force application support. The plug-in cable elbow type head detacher disclosed by the invention has the advantages of simple structure, low manufacturing cost, good detaching effect, high detaching efficiency, high practicability and the like, and is applicable for elbow type head detaching of switch cabinets of different factories; and according to the plug-in cable elbow type head detacher disclosed by the invention, the disassembling time of the whole elbow type head is reduced to be 20 min from 70 min without damaging the elbow type head.

Description

technical field [0001] The invention relates to the field of switchgear, in particular to a plug-in cable elbow removal tool. Background technique [0002] In recent years, with the continuous development of social economy and switch technology, the complexity of engineering construction has increased, and miniaturized, intelligent, and maintenance-free switchgear has become more and more popular. The 10kV gas-insulated switchgear (referred to as gas-filled switchgear) is the equipment that adapts to this trend. It uses SF 6 Gas is used as an insulating medium, which greatly reduces the volume of the cabinet. The 10kV gas insulated switchgear cabinet is small in size, so its outlet adopts the cable access method, and the touchable plug-in cable elbow is used when connecting the cable. [0003] In order to facilitate cable repair, maintenance and preventive tests, it is usually necessary to disassemble the 10kV plug-in cable elbow. The disassembly process is to separate the...
