Description

A portable high-voltage fuse disassembly device

technical field

The utility model belongs to the technical field of electrical operation tools, in particular to a portable high-voltage fuse disassembly device.

Background technique

In the high-voltage switchgear with a voltage level of 35KV and below in the substation, when the busbar is not powered off and a high-voltage fuse needs to be installed and removed, due to different switchgear manufacturers, the installation positions of the designed primary high-voltage fuse are also different, some are deep, and some are deep. High, when installing and disassembling, the operator needs to penetrate into the switch cabinet to install and disassemble normally, which leads to the very close distance between the operator and the live equipment. At the same time, when the lighting in the high-voltage cabinet is insufficient, it is necessary to use a flashlight for auxiliary lighting before operating. In this way It will greatly increase the work risk factor for the operation and maintenance operators, seriously affecting the personal safety of the operators and the stable operation of the equipment.

Utility model content

In order to overcome the deficiencies of the existing technology and solve the technical problem of inconvenient installation and disassembly of high-voltage fuses by operation and maintenance operators, the utility model provides a portable high-voltage fuse disassembly device.

The utility model is realized through the following technical solutions.

A portable high-voltage fuse disassembly device, which includes a handle, an insulating rod and a hook body, the insulating rod includes a first connecting rod and a second connecting rod, the rod of the first connecting rod is provided with external threads, and the lower end of the first connecting rod is fixed Installed on the handle, an insulating sleeve is provided to cooperate with the external thread of the first connecting rod, and the outer wall of the upper end of the insulating sleeve is fixedly installed with a hook body. The lower end of the two connecting rods is provided with a card slot in cooperation with the block. The block rotates in the card slot. The first connecting rod drives the second connecting rod to reciprocate up and down in the insulating sleeve. The upper end of the second connecting rod A high-voltage fuse bracket is fixedly arranged, and an illuminating device is detachably arranged at the opening of the hook body.

Further, the length of the second connecting rod is greater than the depth of the hook portion of the hook.

Further, the second connecting rod is in clearance fit with the insulating sleeve.

Compared with the prior art, the utility model has the following beneficial effects.

1. The upper end of the second connecting rod is fixed with a high-voltage fuse bracket, and different types of high-voltage fuses can be replaced in the high-voltage fuse bracket according to needs.

2. The outer wall of the upper end of the insulating sleeve is fixed with a hook body. The second connecting rod pushes the high-voltage fuse bracket out of the insulating sleeve through the first connecting rod, and drives the high-voltage fuse set in the high-voltage fuse bracket through the rotating handle. The fuse is stuck in the hook body, which is convenient for disassembling and assembling the high-voltage fuse.

3. Equipped with insulating rods, the operator does not need to put his body into the switch cabinet to carry out work during assembly and disassembly, which effectively improves work efficiency and greatly controls potential safety hazards.

4. The lighting equipment is detachably installed at the opening of the hook body, and there is no need for other people's auxiliary lighting when the light is dark or night operation, which makes the division of labor more clear, reduces the tediousness of work, and ensures the accuracy and efficiency of work. , Increase the safety of the operator's work and improve the efficiency of the company's high-quality power supply services.

detailed description

The utility model is described in detail below in conjunction with the implementation examples. The present embodiment is implemented under the premise of the technical solution of the utility model, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the utility model is not limited to the following the described embodiment.

As shown in Figure 1 and Figure 2, a portable high-voltage fuse disassembly device includes a handle 1, an insulating rod and a hook body 5, the insulating rod includes a first connecting rod 21 and a second connecting rod 22, the first connecting rod The 21 rods are provided with external threads, the lower end of the first connecting rod 21 is fixedly installed on the handle 1, and an insulating sleeve 2 is arranged in cooperation with the external threads of the first connecting rod 21, and the outer wall of the upper end of the insulating sleeve 2 is fixedly installed with The hook body 5 is characterized in that: the upper end of the first connecting rod 21 is provided with a clamping block 211, and the lower end of the second connecting rod 22 is provided with a clamping groove 221 in cooperation with the clamping block, and the clamping block 211 rotates in the clamping groove 221 Movement, the first connecting rod 21 drives the second connecting rod 22 to reciprocate up and down in the insulating sleeve 2, the upper end of the second connecting rod 22 is fixedly provided with a high-voltage fuse bracket 3, and the opening of the hook body 5 is detachably provided with Lighting device4.

Further, the length of the second connecting rod 22 is greater than the depth of the hook portion of the hook body 5 , so that the joint between the block 211 and the slot 221 will not disengage from the insulating sleeve 2 when the high-voltage fuse is disassembled.

Further, the second connecting rod 22 is in a clearance fit with the insulating sleeve 2 .
