CN204271509U - A disassembly tool for transformer lead wire - Google Patents

Abstract

The utility model provides a dismantling tool for a transformer drain wire, which is characterized in that it comprises a holder with grooves on it, and a fixing part arranged on the holder. When disassembling the drain wire, only need to place the holder on the drain wire clamping plate in advance and fix it, then the bolts between the clamping plates can be easily installed or disassembled. It avoids the problems of difficult alignment and separation of splint screw holes caused by overweight drain wires, greatly improves disassembly efficiency, and saves time and effort in the entire disassembly process. Due to the pre-installation method, only one operator can complete all disassembly and assembly work. It overcomes the inconvenience and discomfort caused by operators working at high altitudes, reduces the power outage time of the power grid, and improves the reliability of power supply.

Description

A disassembly tool for transformer lead wire

technical field

The utility model relates to a disassembling tool, in particular to a disassembling tool for a transformer drain wire, and belongs to the technical field of design and manufacture of electric equipment auxiliary tools.

Background technique

During the expected test and regular inspection of transformers used in 110kV and above substations, it is necessary to disassemble and assemble the drain wires. When disassembling, it is first necessary to separate or connect the wiring board of the drainage wire with the wiring board on the transmission line, and then the whole drainage wire can be removed or installed. Because the volume and quality of the drainage wires used in the 110kV transmission line are relatively large, the entire disassembly and assembly process is time-consuming and laborious. In addition, operators need to disassemble and assemble at high altitude, which is not only difficult, but also inconvenient for multiple people to cooperate with the operation, which affects the work efficiency. At the same time, long-term work will also affect the normal operation of the substation and increase the power outage time of the power grid. Therefore it is necessary to improve the prior art.

Contents of the invention

In order to solve the problems of inconvenient working at heights and affecting the efficiency of working at heights due to the thick and heavy drain wires when disassembling and assembling the drain wires of transformers, the utility model provides a tool for disassembling and assembling transformer drain wires.

The utility model is completed through the following technical solutions: a transformer drain wire disassembly tool, which is characterized in that it includes a holder with a groove on it, and a fixing piece on the holder, so that the holder can be placed It is placed between the wiring board of the drain wire and the wiring board of the transmission line, and then fixed by a fixing piece, so that the fixing bolts between the wiring boards can be easily removed or installed, and then the drain wire can be easily connected or separated.

The clamp includes upper and lower horizontal splints, vertical connecting plates connected to the same ends of the upper and lower horizontal splints, the upper and lower horizontal splints and the vertical connecting plates form a side U concave groove, and the upper horizontal splint is provided with There are screw holes to place the wiring board in the U-shaped groove on the side.

The fixing part includes a vertical screw arranged in the screw hole of the upper horizontal splint. The upper end of the vertical screw extends upward through the screw hole of the upper horizontal splint of the holder and is connected with the handle. The lower end of the vertical screw is located at the side of the holder. In the U concave groove, and connected with the compression cap, so that when the wiring board is placed in the U concave groove on the side of the holder, the operating handle moves the screw up and down, and the compression cap is compressed or loosened. Wiring board to complete the disassembly and assembly of the drain wire.

The compression cap is configured as a conical body with a small upper end and a larger lower end, and the upper end of the conical body is connected with the end of the screw rod.

The utility model has the following advantages and effects: adopting the above-mentioned scheme, when disassembling and assembling the drain wire, only need to place the clamper on the drain wire clamping plate in advance and fix it, and then it can be easily fixed between the clamping plates. bolts for installation or removal. It avoids the problems of difficult alignment and separation of splint screw holes caused by overweight drain wires, greatly improves disassembly efficiency, and saves time and effort in the entire disassembly process. Due to the pre-installation method, only one operator can complete all disassembly and assembly work. It overcomes the inconvenience and discomfort caused by operators working at high altitudes, and reduces the power outage time of the power grid to improve the reliability of power supply. It is an ideal disassembly tool.
