Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage circuit breakers, in particular to an auxiliary tooling for a withstand voltage test of a high-voltage circuit breaker. Background Art

[0002] High-voltage circuit breakers (referred to as "circuit breakers") have overload, short circuit and undervoltage protection functions, and the ability to protect lines and power supplies. They can effectively protect the normal operation of box-type substations. Appropriate circuit breakers are selected according to different altitudes and customer needs. Before the circuit breaker is hoisted into the cabinet, it needs to be subjected to a withstand voltage test to ensure that it works under normal conditions. The operating steps of the withstand voltage test are as follows:

[0003] 1.1 Transport the circuit breaker placed upside down on the pallet to the test position. Since the circuit breaker is an irregular body and cannot stand upright, the supplier provides the circuit breaker upside down on the pallet. However, the circuit breaker placed upside down on the pallet will result in insufficient distance from the ground, affecting the test results. Therefore, a crane is needed to assist the circuit breaker to stand upright before testing.

[0004] 1.2 Turn on the high voltage power supply and set the voltage value;

[0005] 1.3 Connect the circuit breaker to the power supply and measuring instruments for testing;

[0006] 1.4 Output the test results, turn off the power, and remove the wiring harness;

[0007] 1.5 After the test, use a crane to place the circuit breaker upside down on the tray;

[0008] 1.6 Use a stacker to move the pallet to the front of the cabinet, use a crane to flip the circuit breaker upright, and lift it into the cabinet.

[0009] Since the circuit breaker needs to be placed upside down on a pallet before and after the test, three overhead crane operations are required before and after the test (including two flipping and uprighting), which increases the labor time and easily causes the circuit breaker to be bumped. After the test is completed, a stacker is needed to transfer the circuit breaker back into the cabinet. When there are a lot of materials, the use of the stacker requires waiting, which affects the work efficiency. Utility Model Content

[0010] 1. Technical issues to be resolved

[0011] In order to solve the above problems in the prior art, the utility model provides an auxiliary tooling for a high voltage circuit breaker withstand voltage test, which can improve the working efficiency.

[0014] The auxiliary tooling assembly includes a main beam, a tooling frame and wheels, the wheels are spaced apart at the bottom of the tooling frame, the main beam is vertically fixed to the bottom of the tooling frame, the tooling frame and the main beam form an L-shaped structure, and the side wall of the tooling frame is provided with mounting holes, which are used to install and fix the high-voltage circuit breaker.

[0015] Furthermore, a plurality of mounting holes of different sizes are provided on the side wall of the tooling frame at intervals along its extending direction.

[0016] Furthermore, it also includes a first reinforcing rib;

[0017] The first reinforcing rib is obliquely arranged on one side of the main beam, one end of the first reinforcing rib is connected to one side of the top of the tooling frame, and the other end of the first reinforcing rib is connected to a side wall of the main beam.

[0022] (III) Beneficial effects

[0023] The beneficial effect of the utility model is that when conducting a withstand voltage test on a high-voltage circuit breaker, the high-voltage circuit breaker placed upside down on a pallet is first fixed upright between two auxiliary tooling components by a crane. After the test is completed, the high-voltage circuit breaker is directly transferred to the front of the cabinet by the tooling, and lifted by a crane. The installation fixtures between the auxiliary tooling components and the high-voltage circuit breaker are loosened, and the high-voltage circuit breaker can be directly placed in the cabinet.
