Problems solved by technology

[0007] The purpose of the present invention is not only to have the same function of unblocking the passage of the main shaft of the tubular tap-changer and other core structures attached to it, but also to overcome the failure of the main shaft of the tubular tap-changer to be installed in place and to directly open the gate. Deficiencies in fixing and unlocking core pulling

Abstract

The invention provides an installation and detachment plate brake of a tapping switch, wherein the mode of delicate assembly and convenient maintenance of the transformer tapping switch of the power transmission and transformation field is introduced. The installation and detachment plate brake is characterized in that a gate can be opened through the insertion or pull-out of a gate key as a key to enable a main shaft of the tapping switch and an attached core portion structure of the main shaft to be pushed into an insulation housing chamber body of the tapping switch to be assembled in place after being assembled outside delicately, or the operation is performed in an opposite mode, the main shaft and the attached core portion structure of the main shaft can be drawn out of the insulation housing chamber body of the tapping switch when a fault of the tapping switch is caused in a transformer, the fault cause can be checked, and the main shaft and the attached core portion structure of the main shaft can be arranged in situ after maintenance to continue to running.

Description

technical field [0001] The present invention relates to the exquisite assembly and simple maintenance of transformer tap changers in the field of power transmission and transformation, specifically creating a "Disassembly and Assembly of Tap Switches", which uses a switch key to insert or pull out It is like a key that can be opened and pulled out or put into the internal structure of the main shaft of the locking tap changer and its accompanying switching mechanism for each phase of the contact piece (hereinafter collectively referred to as the core structure), so that the core structure can be delicately assembled on the outside. Then push it into the cavity of the tap changer and lock it in place. When the transformer fails, you can directly use the switch key from the transformer box cover to open the switch and pull out the main shaft and core structure to check whether it is a tap changer. It can be repaired and maintained immediately, and it is easy to install and resum...
