[0002] With the continuous advancement of my country's power system technology, the research and development capabilities of major high-voltage electrical equipment manufacturing companies have continued to increase, and the structure of high-voltage switches has become more reasonable and the performance has become more reliable, making high-voltage electrical equipment in my country widely used. Isolating switches are widely used in high-voltage transmission projects due to their compact structure and high reliability. Isolating switches are switching devices that have insulation distances that meet specified requirements and obvious disconnection signs between contacts when in the open position; when in the closed position, they can carry current under normal circuit conditions and current under abnormal conditions (such as short circuits) within a specified time. As an important component of gas-enclosed switchgear (GIS), isolating switches have the following functions: Isolating the power supply: reliably isolating electrical equipment that needs to be repaired or is in standby mode from live parts to ensure the safety of personnel and equipment; switching operations: achieving switching between different circuits and changing the operating mode of the power system.

[0003] To ensure the normal operation of the disconnector, it is particularly important to determine the open and closed positions. Currently, during the assembly process of the combination electrical disconnector, three positions need to be determined, namely the middle position, the open position, and the closed position. The original assembly process used three sets of tooling, and different tooling needs to be replaced each time a position is determined. This requires the collaboration of multiple people to complete, making the operation cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0004] In order to overcome the defects in the prior art that different tooling needs to be replaced each time a position is determined, which is time-consuming and labor-intensive, the utility model provides a GIS disconnector assembly positioning tooling.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a GIS disconnector assembly and positioning tool, including a centering rod, a base plate, a locking bolt and a fixing plate, the base plate is installed at the right end of the disconnector housing, a through hole is opened in the middle of the base plate, a transition cylinder is installed on the left side of the base plate, a left positioning platform is provided at the left end of the centering rod, a positioning step is provided at the middle position of the centering rod, the right end of the centering rod is slidably placed in the transition cylinder, a connecting bolt for connecting the centering rod is provided on the fixing plate, a positioning hole for inserting a positioning pin is provided on the centering rod, and the fixing plate is fixed to the thread hole position on the base plate by the locking bolt.

[0006] As a further improvement of the present invention, the transition tube and the through hole are located on the same axis.

[0007] As a further improvement of the present invention, the inner diameter of the transition cylinder is the same as the diameter of the through hole.

[0008] As a further improvement of the present invention, the locking bolts are symmetrically arranged on the fixing plate.

[0009] As a further improvement of the present invention, the connecting bolt is arranged at the center position of the fixing plate.

[0010] Compared with the existing technology, the utility model has the following beneficial effects: the tooling adopts the flange surface of the isolating switch housing for positioning, with high positioning accuracy, effectively improving the assembly quality, integrating the original three sets of tooling into one set of tooling, and realizing the positioning of the opening and closing positions through locking limits at different positions, with simple structure, low cost, easy installation and use, reducing the number of operators, and greatly improving the installation efficiency and accuracy.
