[0002] The sealed pole is an important component in high-voltage switchgear, which has the functions of insulation and sealing. At present, when the performance (power frequency, lightning impulse, partial discharge) of the sealed pole is tested, the base insert is generally screwed and the copper wire is wrapped around the screw, and the insulating rod is grounded as a whole; it is time-consuming and labor-intensive, with high labor intensity and low production and testing efficiency.

[0003] The base insert hole in the fusion-sealed pole is not only related to the structural integrity of the product, but also to the electrical performance and mechanical stability of the product.

The tool includes a base, at least two positioning pins and a detection plate. The positioning pins are arranged on the base. Each positioning pin corresponds to a threaded insert. The outer diameter of the positioning pin is equal to the minor diameter of the threaded hole in the threaded insert. A reference surface is provided on the base, and the reference surface is used to fit with the installation end surface; the detection plate is relatively fixed to the base and parallel to the reference surface; the thickness of the detection plate is equal to the tolerance of the length of the insulating pull rod extending out of the sealed pole, and the distance between the side of the detection plate facing the reference surface and the reference surface is equal to the theoretical length of the insulating pull rod extending out; a circular hole is opened on the detection plate, and the diameter of the circular hole is equal to the sum of the diameter of the end of the insulating pull rod extending out of the sealed pole and the assembly tolerance of the insulating pull rod perpendicular to its axis, and the axis of the circular hole coincides with the theoretical axis of the insulating pull rod. Although the tool can realize the installation accuracy detection of the insulating pull rod, the patent application cannot realize the base connection efficiency when integrating the detection of the sealed pole.

[0026] The present invention is described in detail below with reference to the accompanying drawings.

[0030] Optionally, a window for installing a vacuum interrupter contact separation tooling is provided in the center of the detection plate 1 of a sealed pole quick plug-in detection device of the present invention, and the positioning rod 2 is fixed to the outside of the window on the detection plate 1. The detection plate 1 of the sealed pole quick plug-in detection device of the present invention is designed with a window for installing a vacuum interrupter contact separation tooling in the center, so that the vacuum interrupter contact separation tooling can be installed without affecting the fracture performance test of the product, and the weight can be reduced and the labor efficiency can be improved.

[0034] Optionally, in this embodiment, the sealed pole body 4 adopts EP6510 series fusion sealed pole.

[0035] Specifically, a current transformer is provided in the insert hole 6 .

[0036] Optionally, in this embodiment, the sealed pole base 5 is connected to a lower outlet structure.

[0037] Optionally, in this embodiment, the solid-sealed pole body 4 is a single- and double-fused solid-sealed pole.

[0038] Optionally, in this embodiment, the sealed pole body 4 is connected to an upper outlet structure. Further, in this embodiment, the upper outlet structure is connected to a high voltage line.

[0039] Optionally, the quick-pull plug is a lantern plug.

[0041] Specifically, the detection board 1 is provided with a mounting hole 3, and the positioning rod 2 is mounted in the mounting hole 3. The position of the mounting hole 3 on the detection board 1 corresponds to the position of the insert hole 6 one by one.

[0042] The detection plate 1 is provided with mounting holes 3 of different diameters, and a positioning rod 2 of a corresponding diameter is installed in the mounting hole 3 of each diameter.

[0043] Optionally, the diameters of the quick-pull plugs of the positioning rods 2 of different diameters are different.

[0044] Optionally, in this embodiment, a window for installing the vacuum interrupter contact separation tooling is provided in the center of the detection plate 1, and the positioning rod 2 is fixed to the outside of the window on the detection plate 1. Through the window, it is convenient to install the vacuum interrupter contact separation tooling without affecting the fracture performance test of the product, and it can reduce weight and improve labor efficiency.

[0045] Optionally, the detection plate 1 and the positioning rod 2 are both made of cast aluminum, which can reduce the weight and improve labor efficiency.

By replacing the positioning rods 2 of different lengths, the detection requirements of all types of sealed pole bodies 4 in this series can be met.

Furthermore, the detection plate 1 of the device for rapid plugging and unplugging of a sealed pole in the present embodiment is hollowed out in the center, which does not affect the installation of the vacuum arc chamber contact separation tooling when the fracture performance test is performed on the product at the same time. A device for rapid plugging and unplugging of a sealed pole in the present embodiment can be quickly plugged in and out by integrating the particularity of the performance test of the high-voltage capacitor of the sealed pole before and after glue filling, and can meet the performance test requirements of the full range of poles by replacing the positioning rod 2 of different lengths.

Optionally, two first threaded holes are provided on the detection plates on opposite sides of the rectangular window. The four first threaded holes are distributed according to the corner points of the rectangle, and the diameters of the four first threaded holes are the same. Furthermore, two second threaded holes are provided on the outside of the long side of the expansion window away from the rectangular window, and five second threaded holes are provided on the outside of the long side of the rectangular window away from the expansion window.
