Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment insulation testing technology, and in particular relates to an insulation lifting and carrying conveying system for electrical equipment insulation testing. Background Technology

[0002] Traditional electrical equipment insulation testing platforms, when supporting electrical equipment to the insulation testing position, are not suitable for supporting various types, shapes, and sizes of electrical equipment because the support plates on the platform are all fixed and the structure, leg distribution, and size of the bottom of the electrical equipment vary. They also lack a flexible distribution and layout design for the insulation bearing surface, thus failing to meet the requirements of high insulation protection and flexible adjustment. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides an insulation lifting and carrying conveying system for insulation testing of electrical equipment. Through the design of electromagnetic adsorption to dynamically adjust the support position of the equipment, it can realize the rapid adaptation and support of electrical equipment, and significantly improve the applicability of the insulation carrying system to electrical equipment of different sizes and shapes.

[0004] Technical Solution: To achieve the above objectives, the present invention provides an insulation lifting and carrying transport system for insulation testing of electrical equipment, comprising an insulation lifting and carrying platform that transports electrical equipment from a loading position to a testing position via a smart trolley along a predetermined guide rail. The insulation lifting and carrying platform is height-adjustable, and its platform has a groove-shaped insulation carrying surface. The upper and lower surfaces of the groove-shaped insulation carrying surface are respectively provided with a plurality of equipment support plates and an electromagnetic plate. The equipment support plates and the electromagnetic plate are magnetically attracted to each other, and the plurality of equipment support plates can adjust their support positions according to the placement and contact positions of the electrical equipment.

[0005] Furthermore, the equipment support plate is limited by the groove edge of the groove-shaped insulating bearing surface to prevent it from falling out of the groove.

[0006] Furthermore, it includes a power supply system corresponding to the electromagnetic plate, which adjusts the magnetism of the electromagnetic plate by switching between power on and power off;

[0007] When the electromagnetic plate is magnetized by power, it magnetically attracts the equipment support plate, keeping the equipment support plate relatively fixed to the insulated lifting platform.

[0008] When the power is off and the electromagnetic plate is demagnetized, the equipment support plate is moved on the slotted insulating bearing surface by external force to adjust the support position.

[0009] Furthermore, the bottom of the insulated lifting platform is equipped with a pull-out box via a pull-out guide rail or a pull-out telescopic rod, and the power supply system is located inside the pull-out box; and the pull-out box can be pulled out horizontally, so that the power supply system can be moved out of the insulated lifting platform.

[0010] Furthermore, the equipment support plate is composed of an iron plate with an insulating and vibration-damping plate laid on its surface.

[0011] Furthermore, the groove-shaped insulating bearing surface is composed of a rubber liner, an epoxy insulating blanket, and a ceramic fiber insulating board from top to bottom.

[0012] Furthermore, the insulation strength of the rubber gasket, epoxy insulating blanket, and ceramic fiber insulating board increases sequentially, forming a progressive insulation structure.

[0013] Furthermore, the intelligent vehicle is equipped with an infrared positioning sensor, and automatically detaches after transporting the insulated lifting platform to the test position.

[0014] Furthermore, the bottom of the insulated lifting platform is provided with a lifting drive unit to drive its lifting and lowering movements.

[0015] Beneficial effects: This utility model achieves stepless adjustment of the position of the equipment support plate through electromagnetic adsorption, adapting to electrical equipment of different models, sizes and shapes, significantly improving the applicability to insulation bearing capacity of various electrical equipment. The electromagnetic on / off switch can be switched in a short time. After the equipment support plate is adjusted to the correct position, it is fixed by electromagnetic adsorption. During the transportation process, the magnetic adsorption of the equipment support plate is maintained until it is transported to the position for insulation testing, after which the power is cut off to prevent subsequent impact on the insulation test of the electrical equipment.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figure 1 and Figure 2As shown, an insulation lifting and carrying transport system for insulation testing of electrical equipment includes an insulation lifting and carrying platform 1 that transports electrical equipment from a loading position to a test position via a smart trolley 2 along a predetermined guide rail 3. The system is characterized by its height-adjustable design. Its platform has a groove-shaped insulation carrying surface 4, with several equipment support plates 5 and an electromagnetic plate 6 respectively disposed on the upper and lower surfaces of the groove-shaped insulation carrying surface 4. The equipment support plates 5 and the electromagnetic plate 6 are magnetically attracted to each other, and the support positions of the equipment support plates 5 can be adjusted according to the placement and contact position of the electrical equipment. This invention achieves stepless adjustment of the position of the equipment support plates 5 through electromagnetic attraction, adapting to electrical equipment of different models, sizes, and shapes (such as irregularly shaped transformers and multi-interface switchgear), significantly improving the applicability to insulation carrying of various electrical equipment. The electromagnetic on / off switch can be made in a short time. After the equipment support plates 5 are adjusted to the correct position, they are fixed by electromagnetic attraction. During transport, the magnetic attraction of the equipment support plates 5 is maintained until they are transported to the insulation test position, after which the power is cut off to prevent subsequent interference with the insulation test of the electrical equipment.

[0021] The equipment support plate 5 is limited by the groove edge of the groove-shaped insulating bearing surface 4 to prevent it from falling out of the groove. The combination of physical limitation and electromagnetic adsorption completely eliminates the risk of the equipment support plate 5 falling out of the groove.

[0022] This utility model also includes a power supply system 7 corresponding to the electromagnetic plate 6. The power supply system 7 adjusts the magnetism of the electromagnetic plate 6 by switching between power on and power off. When powered on, the electromagnetic plate 6 is magnetized, and it magnetically attracts the equipment support plate 5, keeping the equipment support plate 5 relatively fixed to the insulated lifting support platform 1. When powered off, the electromagnetic plate 6 is demagnetized, and the equipment support plate 5 is driven by external force to move on the slotted insulated support surface 4 to adjust its support position. The "fixed-adjustment" mode switching is achieved through a single power supply control, with a short operation response time. When the power is off, only external force is needed to adjust the equipment support plate 5, such as manual operation to adjust its position.

[0023] When conducting insulation tests on electrical equipment, the fact that the power supply system 7 is located below the electrical equipment may affect the insulation test results. To eliminate this effect, in this invention, the bottom of the insulation lifting platform 1 is equipped with a pull-out box 8 via a pull-out guide rail or a pull-out telescopic rod, and the power supply system 7 is located inside the pull-out box 8. Furthermore, the pull-out box 8 can be pulled out horizontally, allowing the power supply system 7 to move out of the insulation lifting platform 1. Thus, the power supply system 7 will not be located below the electrical equipment during the insulation test, eliminating the interference caused by the power supply system 7 and reducing the error in the insulation test of the electrical equipment.

[0024] like Figure 3As shown, the equipment support plate 5 is composed of an iron plate 51 covered with an insulating and vibration-damping plate 52. The iron plate 51 provides high-strength support, while the insulating and vibration-damping plate 52 is a rubber plate that not only provides insulation but also absorbs equipment vibration, preventing distortion of test data. The groove-shaped insulating bearing surface 4 is composed of a rubber pad 4.1, an epoxy insulating blanket 4.2, and a ceramic fiber insulating board 4.3, arranged from top to bottom. The insulation strength of the rubber pad 4.1, epoxy insulating blanket 4.2, and ceramic fiber insulating board 4.3 increases sequentially, forming a progressive insulation structure. The insulation strength increases stepwise from rubber (12-20kV / mm) to epoxy (20-25kV / mm) to ceramic (≥40kV / mm), which can disperse voltage stress, reduce electric field concentration at the interface of the insulation layer, and extend the service life.

[0025] The intelligent vehicle 2 is equipped with an infrared positioning sensor. Infrared positioning ensures the accuracy of the transportation path. After transporting the insulated lifting platform 1 to the test position, the intelligent vehicle 2 automatically evacuates to prevent the intelligent vehicle 2 from staying and causing electromagnetic interference.

[0026] The bottom of the insulated lifting platform 1 is provided with a lifting drive unit 9 that drives its lifting and lowering movements. The lifting drive unit 9 can be hydraulically or electrically driven.

[0027] Initially, the insulating lifting platform 1 rises, and the intelligent trolley 2 moves to below the insulating lifting platform 1. Then, the insulating lifting platform 1 descends, and the lifting drive unit 9 shortens until it leaves the ground. The intelligent trolley 2 carries the insulating lifting platform 1 and the electrical equipment to be tested for insulation to the test position. After reaching the test position, the lifting drive unit 9 extends to touch the ground, the insulating lifting platform 1 rises and detaches from the intelligent trolley 2, the intelligent trolley 2 is withdrawn, the power supply system 7 is de-energized, and at the same time, the pull-out box 8 is pulled to move the power supply system 7 outside the insulating lifting platform 1. Then, the insulation test of the electrical equipment can be carried out.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
