Abstract
Description
Technical Field
[0001] The present application relates to the technical field of voltage transformer assembly, and specifically discloses a three-phase combined voltage transformer body positioning tool. Background Art
[0002] The three-phase combined voltage transformer is a combination device composed of two separate bodies. The body is composed of an iron core, a coil and a conductive rod. The coil is sleeved on the iron core. A conductive rod is welded in the middle of the coils of the two bodies, and conductive rods are welded on the outside of the coils of the two bodies respectively. Therefore, the position of the combined body and the insulation distance between the two sets of coils play a vital role in the subsequent processes and the quality of the entire voltage transformer.
[0003] The existing three-phase combination voltage transformer is assembled by visual inspection and local positioning during installation, which results in a difference between the insulation distance between the coils visually observed and the insulation distance actually required, and is not accurate enough, resulting in the quality of the assembled product not being guaranteed. Therefore, in view of this, the inventor provides a three-phase combination voltage transformer body positioning tool to solve the above problem. Utility Model Content
[0004] The utility model aims to solve the problem that the insulation distance of the traditional three-phase combined voltage transformer is determined by visual inspection and local positioning during assembly, which makes the installed insulation distance inaccurate and affects the quality of the product.
[0005] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a three-phase combination voltage transformer body positioning tool, including a base plate and support vertical plates symmetrically arranged at both ends of the base plate, the inner sides of the support vertical plates are symmetrically provided with support sleeves, the two ends of the iron core are respectively detachably nested with the support sleeves located at both ends of the base plate, the top of the outer end of the support sleeve is provided with a limit vertical rod for limiting the coil at the end of the iron core, and a measuring piece for measuring the insulation distance of two separate bodies is provided between the two limit vertical rods located on one side of any support vertical plate, the measuring piece includes a first slide bar and a second slide bar respectively connected to the limit vertical rods on the two support sleeves located on the same side, a slide groove is provided on the side of the second slide bar close to the first slide bar, a measuring slide bar that can slide in the slide groove is provided on the side of the first slide bar close to the second slide bar, a scale line groove for displaying the length of the measuring slide bar and evenly distributed is provided on one side of the measuring slide bar, and a limit baffle for limiting the coil on the side of the iron core is provided on the side of the first slide bar and the second slide bar away from the support vertical plate.
[0006] The principles and effects of this basic solution are:
[0007] 1. Compared with the prior art, the utility model provides a bottom plate, a supporting plate and a supporting sleeve, so as to facilitate the hanging installation of the device body during the assembly process and facilitate positioning. By providing a limiting vertical rod, it is convenient to limit the winding range of the coil mounted on the iron core during the assembly process, so as to facilitate the control of the winding tightness of the coil.
[0008] 2. Compared with the prior art, the utility model can not only limit the outer side of the coil during the process of winding the coil on the iron core by setting a limit baffle, but also can more intuitively measure the insulation distance between the two groups of coils. By setting a measuring slide bar on the first slide bar, a slide groove on the second slide bar and a scale line groove on the measuring slide bar, it is convenient to directly measure the distance between the two limit baffles, and then add the measured distance to the thickness of the two limit baffles, so as to indirectly obtain the insulation distance of the two groups of separate bodies. By directly reading the distance shown by the scale line groove, the accurate insulation distance can be obtained, so that the assembled three-phase combination voltage transformer is more in line with the actual production requirements, the quality of the product is improved, and the problem that the traditional three-phase combination voltage transformer adopts the method of visual inspection and local positioning to determine the insulation distance of the body during assembly, which makes the installed insulation distance inaccurate and affects the quality of the product is solved.
[0009] Furthermore, the support sleeve includes a fixed sleeve arranged on the inner side of the support plate and a mounting groove arranged on the side of the fixed sleeve and capable of accommodating the iron core to be embedded. The side of the limiting vertical rod away from the support plate is located in the same vertical plane as the end face of the fixed sleeve. Through the vertical fixed sleeve and the mounting groove, the two ends of the iron core are embedded and installed in the mounting groove of the fixed sleeve, which not only supports the iron core, but also limits the iron core. At the same time, the end face of the fixed sleeve and the limiting vertical rod can also limit the coil on the iron core.
[0010] Furthermore, the first slide bar and the second slide bar each include a transverse slide bar slidably connected to the limiting vertical bar and a vertical slide bar provided at the inner end of the transverse slide bar, the limiting baffles are both located on the side of the vertical slide bar away from the supporting vertical plate, and the side of the limiting baffles close to the measuring slide bar is both arranged flush with the side of the vertical slide bar. By providing the transverse slide bar and the vertical slide bar, it is not only convenient to measure the insulation distance, but also convenient to install and use the limiting baffle, so as to better play its limiting role on the coil.
[0011] Furthermore, the ratio of the distance between the two opposing support sleeves to the length of the limiting baffle is not greater than 3. By limiting the length of the limiting baffle, the limiting baffle has a better limiting effect on the coil. BRIEF DESCRIPTION OF THE DRAWINGS
