[0032] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model, that is, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments.

[0033] The components described and shown in the accompanying drawings and embodiments of the present utility model can be arranged and designed in various different configurations. Therefore, the detailed description of the embodiments of the present utility model provided in the following drawings is not intended to limit the scope of the present utility model to be protected, but only represents a selected embodiment of the present utility model. Based on the accompanying drawings and embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present utility model.

[0034] It should be noted that: the term "comprising", "including" or any other variant is intended to cover non-exclusive inclusion, so that a process, element, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to the process, element, method, article or device.

[0035] The features and performance of the present utility model are further described in detail below in conjunction with the embodiments.

[0036] The present utility model aims at the deficiencies of the prior art, such as Figure 1As shown in the figure, an alignment detector for the static and dynamic sides of a disconnector is designed, which includes an alignment tooling body 2 and a display 4. During use, the alignment tooling body 2 is installed on the static-side component 3 of the disconnector, and one end of the display 4 is connected to the dynamic-side component 1 of the disconnector through a cable, and the other end is connected to the alignment tooling body 2. When the dynamic side contacts the static side, the central positions should be the same. By installing the alignment tooling body 2 on the static side, it can quickly detect whether the alignment is qualified. If it is unqualified, it can also detect the offset direction of the dynamic and static sides, which is convenient for adjustment. And it will not damage the inner surface of the parts, and can be applied to the alignment verification of similar large-diameter dynamic and static contacts. The device has a simple structure and convenient operation, and can accurately and efficiently detect the alignment of the dynamic and static sides of the disconnector, improving the assembly efficiency and assembly accuracy.

[0037] As Figure 2 shown in the figure, the alignment tooling body 2 designed by the present utility model includes an upper positioning plate 5 and a lower positioning plate 6. Both the upper positioning plate 5 and the lower positioning plate 6 are made of insulating materials and are assembled into one body with 4 bolts. There are 12 metal thimbles evenly distributed on the upper positioning plate 5. When the copper-tungsten contact on the dynamic side of the disconnector makes rigid contact with the 12 thimbles, the thimble circuit is conducted. The offset direction of unqualified alignment can be accurately positioned.

[0038] Specifically, as Figure 3 shown in the figure, the thimble consists of a moving thimble 9, a spring 8 and a static thimble 7, all of which are made of metal, generally stainless steel. When the moving contact touches the thimble, the circuit can be conducted, and it is possible to judge whether the alignment is qualified by observing the indicator light, and further alignment adjustment can be carried out according to the indicator light situation.

[0039] A plurality of upper positioning slots are prefabricated in the upper positioning plate 5, and a plurality of lower positioning slots are prefabricated in the lower positioning plate 6. The moving thimble 9 is matched with the upper positioning slot, the static thimble 7 is matched with the lower positioning slot, and the spring 8 is installed between the moving thimble 9 and the static thimble 7 and can be compressed and rebound.

[0040] The present utility model also designs a display 4 and its circuit. As Figure 4 shown in the figure, a plurality of thimbles evenly distributed on the tooling are connected in series with indicator lights and resistors and then connected in parallel to the circuit. The thimbles and indicator lights are numbered correspondingly. By observing the indicator light situation, it can be judged whether the alignment is qualified, and further alignment adjustment can be carried out according to the indicator light situation. When any one circuit is not conducted, the indicator light of this circuit does not light up, indicating that the alignment is unqualified. When all 12 circuits are conducted, all the indicator lights are on, and the alignment is qualified. It can be directly observed through the panel of the display 4.

[0041] The overall structure after the installation of the present utility model is as Figure 1, in the figure, one side of the moving-side group component 1 of the disconnector is connected to the circuit and is connected in series to the loop; the centering tooling body 2 realizes a transition fit with the hole positions of the static-side group component 3 of the disconnector by relying on the bottom boss; the centering tooling body 2 is connected to the circuit and is connected in series to the loop; when the circuit is turned on, the centering situation will be displayed on the display 4.

[0042] As Figure 5 shown, indicator lights 12 corresponding to the number of thimbles are designed on the panel of the display 4, and a power switch 11 and a main indicator light 10 are also provided. Figure 5 In, the indicator lights 12 are arranged in a circular array, corresponding to the circular arrangement of the thimbles.

[0043] The display 4 is connected in series to the loop. After closing the power switch 11, operate the moving contact of the disconnector to move towards the static contact and contact the centering tooling body 2. There are 12 evenly distributed thimbles on the centering tooling body 2, and it is a parallel structure. In each parallel circuit, a thimble, an indicator light 12 and a resistor are connected in series. When the thimble is turned on, the main indicator light 10 will light up, and the indicator light 12 in this circuit will light up. The offset direction of the moving and static sides can be judged according to the lighting situation of the indicator light 12. After adjustment, the centering detection is qualified.

[0044] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: the specific implementation manners of the present invention can still be modified or equivalently replaced, and any modification or equivalent replacement without departing from the spirit and scope of the present invention shall be covered by the protection scope of the claims of the present invention.
