Description

Technical Field

[0001] The utility model relates to a portable on-load voltage regulating switch quick operating device, belonging to the technical field of electrolytic aluminum production. Background Art

[0002] When abnormal situations occur in the rectifier units in the electrolytic aluminum workshop, the on-load voltage regulator loses power. At this time, the rectifier units cannot downshift. In order to prepare for power supply to the equipment, manual downshifting is required. The gear position is high and the number of units is large. It requires a large number of personnel and physical strength, and consumes a long time, which is not conducive to the smooth recovery of the unit. To address this phenomenon, a portable on-load voltage regulator quick operation device is designed and manufactured. Utility Model Content

[0003] In view of the above deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a portable on-load tap-changing switch quick operating device to solve the above problems.

[0004] The portable on-load tap-changing switch quick-operating device described in the utility model includes a cylindrical main body, a circular slot hole is opened at the head end of the main body, the inner diameter of the circular slot hole is adapted to the outer diameter of the on-load tap-changing switch, and a cross bar is provided in the circular slot hole; the tail end of the main body is provided with an external hexagonal clamping column, which is adapted to the internal hexagonal clamping slot of the output end of the electric wrench.

[0005] An electric wrench can be used to quickly connect the device to the operating device, allowing personnel to move lightly and quickly, saving a lot of time for accident handling.

[0006] Preferably, the head end of the main body is chamfered to avoid obstruction of vision during docking.

[0007] The tail end of the main body of the utility model is provided with a connecting rod, and the end of the connecting rod is an external hexagonal clamping column.

[0008] Preferably, the main body and the connecting rod are both made of metal and welded together.

[0009] Preferably, the cross bar is made of metal and is welded in the circular slot.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The portable on-load tap-changing switch quick operating device described in the utility model can use a rechargeable electric wrench instead of manual shifting to and from the gears, saving physical effort and increasing the speed, thereby saving a lot of time for accident handling and freeing up personnel for other accident recovery work, thereby improving work efficiency.
