Description

Technical Field

[0001] The utility model belongs to the technical field of the installation of fuses, and particularly relates to a dismounting and mounting device for a drop-out fuse with anti-detachment function. Background Art

[0002] The existing pull rod is an insulating operating rod with a fuse operating tool head. Its structure is simple and the function is single, and it can only be used for closing or separating the drop-out fuse. During the actual on-site operation process, it is easy for the drop-out fuse to accidentally fall off, which has a certain degree of danger. When it is necessary to remove the fuse bushing for maintenance and reinstall it, it is very difficult for the traditional pull rod to perform precise operation, and it requires live working personnel with certain technical capabilities to repeatedly try to successfully complete the maintenance operation. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the above problems. The present application proposes a dismounting and mounting device for a drop-out fuse with anti-detachment function, which is provided with a pull head that can be remotely controlled to open and close, a support rod for the drop-out bushing, and an arc extinguishing cover, which can ensure smooth and precise operation during the entire process of pulling the rod to open the switch, removing the drop-out bushing, installing the drop-out bushing, and closing the switch. The problem of the drop-out bushing falling off will not occur, and at the same time, no electric arc will be generated, avoiding the occurrence of safety accidents, and effectively ensuring the operation safety of the operating personnel.

[0004] To achieve the above purpose, the utility model provides the following technical solutions: A dismounting and mounting device for a drop-out fuse with anti-detachment function, including a drop-out bushing connected to a high-voltage drop-out fuse. The upper end of the drop-out bushing is provided with a drop-out fuse pull ring for installing a pull head. The pull head is connected to an electric push rod. An arc extinguishing cover is installed below the pull head. A switch is provided on the arc extinguishing cover, located at the lower part of the arc extinguishing cover. A charging port is provided below the arc extinguishing cover. A bushing is provided below the charging port. The bottom of the bushing is an operating rod connection port for installing an operating rod. The side of the arc extinguishing cover is provided with a bushing support rod through a mounting block.

[0005] Further: One end port of the bushing support rod is provided with a semi-circular buckle for supporting the drop-out bushing.

[0006] Further: The electric push rod uses remote control to open and close the pull head.

[0007] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0008] 1. An electric push-pull rod that remotely controls the opening and closing of the pull head is provided, which can effectively prevent the drop-out bushing from falling off;

[0009] 2. The setting of the bushing support rod can accurately disassemble and assemble the drop-out bushing;

[0010] 3. The setting of the arc extinguishing cover effectively eliminates the electric arc generated during the opening and closing of the pull head;

[0011] 4. The operating rod connection port can be used with operating rods of different lengths and can be used for disassembling and assembling the dropout fuse of multiple manufacturers, with strong versatility;

[0012] 5. When this device performs the operation of opening and closing the switch head and the operation of disassembling and assembling the dropout bushing, the operation is simpler and more convenient, reducing the requirements for the skills of the operators for this operation.

[0020] Working principle

[0021] First, use a disassembly tool to insert the switch head into the drop fuse ring.

[0022] Use the remote-controlled electric push rod to open the switch head and snap it into the drop fuse ring to ensure that the switch head does not come out of the ring. At the same time, the sleeve support rod at the bottom is aligned with the drop sleeve.

[0023] When disconnecting the high-voltage drop fuse, use the operating rod to pull open the fuse. At the same time, the drop sleeve falls into the sleeve support rod.

[0024] Remove the sleeve. The bottom of the fuse is connected to the drop sleeve, and the drop sleeve can be taken out by pushing it upward.
