Abstract
Description
Technical Field
[0001] The utility model relates to a pre-installation calibration tool for components inside a switch cabinet used for power supply in a power system, in particular to a calibration device for the lapping surface of a disconnector. Background Art
[0002] At present, for the disconnector inside the switch cabinet used for power supply in the power system, a double-break disconnector is generally adopted. The structure is an iron plate chassis, on the front and rear sides of which three post insulators are respectively installed and fixed. On the three front post insulators, front copper row lapping surfaces are respectively installed, and on the three rear post insulators, rear copper row lapping surfaces are respectively installed. Bolt holes for connecting the copper rows inside the switch cabinet are respectively arranged on the front copper row lapping surface and the rear copper row lapping surface. Front contact seats are respectively installed on the front copper row lapping surface, and rear contact seats are respectively installed on the rear copper row lapping surface. Three conductive shafts are also swingably matched on the iron plate chassis. The front contact and the rear contact of each conductive shaft respectively make on-off cooperation with a corresponding front contact seat and a corresponding rear contact seat. The iron plate chassis is also provided with a control mechanism for controlling the swinging of the three conductive shafts. Since there are often position errors in the installation of the three front copper row lapping surfaces and the three rear copper row lapping surfaces of this double-break disconnector, it is necessary to correct the positions of the front copper row lapping surface and the rear copper row lapping surface before the disconnector is installed into the switch cabinet, so as to avoid that when installed into the switch cabinet, the bolt holes on the front copper row lapping surface or the rear copper row lapping surface cannot be aligned with the bolt holes on the copper row connection part inside the switch cabinet. However, there is currently no special calibration device available for switch cabinet manufacturing factories to conveniently and efficiently calibrate the position of the copper row lapping surface of the disconnector. At present, switch cabinet manufacturing factories calibrate the position of the copper row lapping surface of the disconnector by manual measurement, which has a large amount of labor, troublesome operation and low efficiency. Summary of the Invention
[0003] In order to overcome the problem that switch cabinet manufacturing factories currently calibrate the position of the copper row lapping surface of the disconnector by manual measurement, which has a large amount of labor, troublesome operation and low efficiency, the purpose of the utility model is to provide an improved calibration device for the lapping surface of the disconnector, which can overcome the defects of the prior art.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a calibration device for the lapping surface of a disconnector, characterized in that: it includes a calibration base, a seat plate is arranged on the calibration base, a clamping groove for clamping the lower part of the iron plate chassis of the disconnector is arranged on the seat plate, three front calibration columns are erected on the seat plate in front of the clamping groove, three rear calibration columns are erected on the seat plate behind the clamping groove, front standard position holes for calibrating the bolt holes on the front copper row lapping surface of the disconnector are respectively arranged on the front calibration columns, and rear standard position holes for calibrating the bolt holes on the rear copper row lapping surface of the disconnector are respectively arranged on the rear calibration columns.
[0005] In each of the above technical solutions, each of the front calibration columns can be formed by bending a front metal strip with a U-shaped cross-section by 90 degrees. The vertical portion of the front metal strip serves as the front calibration column, and the horizontal portion of the front metal strip is used as a fixing portion for connecting the seat plate. Each of the rear calibration columns can be formed by bending a rear metal strip with a U-shaped cross-section by 90 degrees. The vertical portion of the rear metal strip serves as the rear calibration column, and the horizontal portion of the rear metal strip is used as a fixing portion for connecting the seat plate. The horizontal portions of the front metal strip and the rear metal strip both extend inward. The end portions of the horizontal portions of the front metal strip and the rear metal strip together form the clamping groove.
[0006] In the above technical solution, the area where the rear standard position hole is provided on the rear calibration column can be recessed inward to adapt to the inwardly recessed structure of the rear copper busbar lapping surface of the disconnector.
[0007] The beneficial effects of the present utility model are as follows: Since it includes a calibration seat, a seat plate is provided on the calibration seat, a clamping groove for clamping the lower part of the iron plate base of the disconnector is provided on the seat plate, three front calibration columns are erected on the seat plate in front of the clamping groove, and three rear calibration columns are erected on the seat plate behind the clamping groove. Standard position holes for calibrating the bolt holes on the copper busbar lapping surface of the disconnector are respectively provided on the front calibration columns and the rear calibration columns. Therefore, the lower part of the iron plate base of the disconnector to be calibrated can be placed on the clamping groove for positioning and fixing. Then, adjust the front and rear positions and the up and down positions of the three front side post insulators so that the bolt holes on the three front copper busbar lapping surfaces respectively align with the front standard position holes on the three front calibration columns. Then, adjust the front and rear positions and the up and down positions of the three rear side post insulators so that the bolt holes on the three rear copper busbar lapping surfaces respectively align with the rear standard position holes on the three rear calibration columns. After fixing the three front side post insulators and the three rear side post insulators, the calibration of the lapping surface of the disconnector is completed. Using the calibration device of the present utility model, the lapping surface of the disconnector can be calibrated simply, conveniently and quickly, and the calibration device has the characteristics of simple structure, convenient operation and high working efficiency.
