Special torque wrench for disassembly/installation of valve tower voltage-sharing electrode

The invention relates to the field of disassembly/installation of extra-high voltage convertor station valve tower voltage-sharing electrodes, and discloses a special torque wrench for disassembly/installation of a valve tower voltage-sharing electrode. The torque wrench comprises a first fixing mechanism, a second fixing mechanism and a third fixing mechanism, wherein the first fixing mechanism is used for fixing the voltage-sharing electrode, the second fixing mechanism is used for connecting and fixing the first fixing mechanism and a welding plastic nut base, the third fixing mechanism isconnected with the second fixing mechanism and realizes relative fixation of the second fixing mechanism and the welding plastic nut base, and the first fixing mechanism and the voltage-sharing electrode can rotate relative to each other. In the process of disassembly/installation of the voltage-sharing electrode, the wrench can ensure that the acting force on a cold water pipe in a convertor valve and the acting force on
