Abstract
Description
Technical Field
[0001] The utility model relates to the field of calibration tools, in particular to a connecting plate calibration tool. Background Technique
[0002] The core component in the 550kV, 6300A combined electrical apparatus is the circuit breaker, which undertakes important functions such as short-circuit fault interruption and capacitive current switching during the operation of the combined electrical apparatus. Therefore, its assembly quality is highly regarded.
[0003] A set of connection structures is designed for the static side part of the 550kV, 6300A combined electrical apparatus circuit breaker. The specific structure is shown in Figure 1 , which mainly consists of an insulator 1, a conductive joint 2, a connecting flange 3, a conductive sheet 4, a connecting plate 5, a horizontal conductive plate 6, and a shielding cover 7. During assembly, the insulator 1 is not fixed first. The conductive joint 2 needs to be fixed on the insulator 1 through bolts first, then the connecting flange 3 is fixed on the conductive joint 2, then the conductive sheet 4 is connected to the connecting flange 3 and the connecting plate 5, then the shielding cover 7 is installed, then the connecting plate is connected to the horizontal conductive plate 6, and finally the insulator 1 is fixed. Thus, the installation of the static side structure is completed.
[0004] During the installation process of the existing static side structure, there is no alignment tool. Due to the assembly gaps of the components, after the conductive joint 2 is connected to the connecting flange 3, the conductive sheet 4, and the connecting plate 5, the connecting plate 5 often has misaligned holes with the horizontal conductive plate 6. Even by adjusting the position of the insulator 1, it cannot be adjusted correctly. At this time, all the assembled static side components need to be disassembled, the direction is adjusted again, and then connected to the horizontal conductive plate 6, which greatly affects the assembly efficiency. And due to poor centering, there is an installation eccentric stress on the static side, affecting the assembly quality. Utility Model Content
[0005] Aiming at the problems existing in the background technique, a connecting plate calibration tool is proposed.
[0006] The utility model proposes a connecting plate calibration tool, which includes nuts, calibration plates, tooling brackets, stud bolts, and screws; the bottoms of two groups of tooling brackets are respectively fixed to both ends of the insulator through two stud bolts, and the convex surface of the insulator faces upward; the tops of two groups of tooling brackets are respectively connected to both sides of a group of calibration plates through two nuts; two screws are installed through the calibration plates and are opposite to the convex surface of the insulator. By cooperating with the installation holes on the connecting plate, the calibration plate and the connecting plate are detachably calibrated and connected.
[0007] Preferably, the screw is an internal hexagonal socket head cap screw.
[0008] Preferably, the nut is a hexagonal nut.
[0009] Compared with the prior art, the utility model has the following beneficial technical effects: By placing the convex surface of the insulator upward, fixing the tooling bracket on the insulator with two stud bolts, then installing the calibration plate, aligning it and locking it with two nuts to ensure that the position of the calibration plate is fixed and does not move during subsequent assembly. Then lock the calibration plate and the connecting plate with two screws to calibrate its position. Through calibration, the assembly of the static side part of the circuit breaker will reach an obviously more accurate positioning state. By finely adjusting the position of the insulator, it is ensured that the connecting plate on the static side of the circuit breaker and the horizontal conductive plate are not misaligned, and at the same time, the time waste caused by repeated disassembly, adjustment and rework is avoided.

[0013] The core component of a 550kV, 6300A combined electrical apparatus is the circuit breaker, which undertakes important functions such as short-circuit fault interruption and capacitive current switching during the operation of the combined electrical apparatus. Therefore, its assembly quality is highly valued.
[0014] A set of connection structures is designed for the static side part of a 550kV, 6300A combined electrical apparatus circuit breaker. The specific structure is shown in Figure 1 , which mainly consists of an insulator 1, a conductive joint 2, a connecting flange 3, a conductive sheet 4, a connecting plate 5, a horizontal conductive plate 6, and a shielding cover 7. During assembly, the insulator 1 is not fixed first. The conductive joint 2 needs to be fixed on the insulator 1 through bolts first, then the connecting flange 3 is fixed on the conductive joint 2, then the conductive sheet 4 is connected to the connecting flange 3 and the connecting plate 5, then the shielding cover 7 is installed, then the connecting plate is connected to the horizontal conductive plate 6, and finally the insulator 1 is fixed. Thus, the installation of the static side structure is completed.
[0015] In order to efficiently and high-quality dock the static side part and solve the problems of misalignment of the connecting plate and rework during the installation of the static side of the circuit breaker. As shown in Figure 2As shown in the figure, a connecting plate calibration tool proposed by the present utility model includes a nut 8, a calibration plate 9, a tooling bracket 10, a stud 11 and a screw 12; the bottoms of two groups of tooling brackets 10 are respectively fixed to both ends of the insulator 1 through two studs 11, and the convex surface of the insulator 1 faces upward; the tops of two groups of tooling brackets 10 are respectively connected to both sides of a group of calibration plates 9 through two nuts 8; two screws 12 are installed through the calibration plate 9 and are opposite to the convex surface of the insulator 1, and through cooperation with the mounting holes on the connecting plate 5, the calibration plate 9 and the connecting plate 5 are detachably and calibratingly connected.
[0016] It should be further noted that the screw 12 is an internal hexagonal socket head cap screw.
[0017] It should be further noted that the nut 8 is a hexagonal nut.
[0018] The working principle is as follows: When assembling the static side of the circuit breaker, first place the convex surface of the insulator 1 upward, and do not tighten the fixing bolts between the connecting flange 3, the conductive sheet 4 and the connecting plate 5 first, and keep them loose. First, fix the tooling bracket 10 on the insulator 1 with two studs 11, then install the calibration plate 9, and after alignment, lock it with two nuts 8 to ensure that the position of the calibration plate 9 is fixed and does not move during subsequent assembly. Then use two screws 12 to connect and lock the calibration plate 9 and the connecting plate 5 respectively through the first and last holes. Then tighten all the loose connecting bolts between the connecting flange 3, the conductive sheet 4 and the connecting plate 5, and mark the lines.
[0019] After calibration, remove the two screws 12 between the calibration plate 9 and the connecting plate 5, loosen the two nuts 8 at the top of the tooling rod, and pull out the calibration plate 9. At this time, the assembly of the static side of the circuit breaker will reach an obvious and more accurate positioning state. Then, by finely adjusting the position of the insulator 1, it is ensured that the connecting plate 5 on the static side of the circuit breaker is not misaligned with the horizontal conductive plate 6, and at the same time, the time waste caused by repeated disassembly, adjustment and rework is avoided.
[0020] The embodiments of the present utility model have been described in detail above with reference to the drawings, but the present utility model is not limited to this. Within the knowledge scope of those skilled in the art to which the present utility model pertains, various changes can be made without departing from the purpose of the present utility model.
