Description

An integrated impact test platform Technical Field

[0001] The present invention relates to the technical field of impulse voltage test devices, in particular to an integrated impulse test platform. Background Art

[0002] In addition to operating at rated voltage for extended periods, power generation, distribution, and consumption equipment within power systems must also demonstrate insulation strength under overvoltage conditions. Overvoltage refers to voltage exceeding normal operating voltage, a voltage increase that can damage electrical equipment or protective devices. A significant proportion of power system incidents are caused by insulation damage due to overvoltage. If insulation oil defects are not promptly corrected, they can ultimately lead to equipment damage. The purpose of high-voltage testing is to verify the reliability of electrical equipment's insulation performance through specific means, instrumentation, and simulation.

[0003] The impulse voltage test is an electrical test conducted on insulating materials for external overvoltage of the power system. The lightning test and operating wave test conducted can effectively simulate the external overvoltage of the power system, and can effectively prevent and test the overvoltage capacity of electrical insulation equipment during power operation.

[0004] At present, the impulse voltage test requires that multiple large test equipment such as impulse generators and voltage dividers be transported to the test site separately, and then assembled and tested in a building block style. The disadvantages are that the equipment is large in size, the transportation process is cumbersome and complicated, the on-site debugging time of the equipment is long, the transfer is difficult, and it cannot be adapted to off-site operations.

The end of the second bracket 10 and the bottom of the impact generator 9 are both connected to a fourth fixing seat 19, which is fixed to the base frame 1. The impact generator 9 is a one-piece structure, completely mounted within a wire-wound epoxy barrel filled with SF6 to enhance insulation strength. This one-piece structure provides strong anti-interference capabilities and adapts to complex field environments.

[0054] One side of the impulse generator 9 is evenly spaced from top to bottom with several horizontal bars. Removable wave tail resistors 13 are located between adjacent bars.

[0055] Furthermore, the second driving device 12 is a hydraulic cylinder, the cylinder body of the hydraulic cylinder is hinged to the fourth fixed seat 19, the fourth fixed seat 19 is fixed to the base frame 1, the end of the piston rod of the hydraulic cylinder is connected to the main body of the second bracket 10, and the piston rod of the hydraulic cylinder pushes the second bracket 10 to rotate.

[0056] Specifically, the second bracket 10 includes a second upper chord, a plurality of second web members and a second lower chord. The second upper chord and the second lower chord are arranged in parallel. The plurality of second web members are arranged between the second upper chord and the second lower chord. The second web member can be a vertical web member, that is, the second web member is vertically arranged between the second upper chord and the second lower chord.

Specifically, the adjustable support leg 21 includes a nut, a screw, and a foot. The nut is sleeved on the screw, one end of the screw is connected to the foot, and the other end of the screw extends into the bottom of the impact generator 9. The length of the adjustable support leg 21 is adjusted by adjusting the length of the screw extending into the bottom of the impact generator 9, and the leg is locked by the nut.

[0060] The integrated impact test platform also includes a hydraulic workstation 3, which is fixed to the base frame 1.

[0061] The working principle of the present invention is as follows:

[0062] During transportation, the voltage divider 4 and the impact generator 9 are both in a lying state, as shown in Figure 5. The first hydraulic clamp 8 locks the voltage divider 4 to the first bracket 6, and the second hydraulic clamp 11 locks the impact generator 9 to the second bracket 10. When in use, the first driving device 7 pushes the first bracket 6 to push the voltage divider 4 up to 90°, and the second driving device 12 pushes the second bracket 10 to push the impact generator 9 up to 90°.

[0063] When used on site, first unfold and fix the equalizing ring 5, fix one end of the flexible wave head resistor 14 to the top of the voltage divider 4, and fix the other end of the flexible wave head resistor 14 to the top of the impact generator 9. The first drive device 7 pushes up the voltage divider 4, and brings up the flexible wave head resistor 14. After the voltage divider 4 is pushed into place, the first hydraulic clamp 8 releases the lock on the voltage divider 4, and the active end of the first drive device 7 retracts to drive the first bracket 6 back to the state during transportation, and then pushes up the impact generator 9. The second hydraulic clamp 11 releases the lock on the impact generator 9, and the active end of the second drive device 12 retracts to drive the second bracket 10 back to the state during transportation. In this way, after the voltage divider 4 and the impact generator 9 are in place, the flexible wave head resistor 14 is automatically propped up, and there is no need to use a ladder to fix the flexible wave head resistor 14 at high altitude.
