Description

Technical Field

[0001] This utility model relates to the field of power safety testing equipment technology, and in particular to a mobile power frequency withstand voltage test device. Background Technology

[0002] Power frequency withstand voltage testing equipment, through the rational use of transformers, voltage dividers, and protective resistors, in conjunction with power frequency withstand voltage instruments, performs insulation strength tests on various electrical products, electrical components, and insulating materials under specified voltages to assess the insulation level of the products and detect insulation defects in the test items. Because the capacitance of the test items is large, or the test voltage requirement is high, the power supply capacity of the testing equipment also has correspondingly high requirements. Typical power frequency withstand voltage testing equipment often consists of large and heavy individual testing instruments, making on-site handling or relocation impossible for ordinary personnel. Split-type power frequency withstand voltage testing equipment, while smaller in size and easier to transport, suffers from drawbacks: components and instruments require cross-operation, connections between devices are cumbersome, additional tooling is needed, and the dispersed equipment requires a large testing area, increasing the workload of handling and testing operations. The numerous components and large footprint also increase the overall cost of the equipment, and components are more susceptible to damage during transportation. Therefore, it is necessary to provide a power frequency withstand voltage testing equipment that is easy to move, simple to operate, and has a small footprint to solve the above technical problems. Summary of the Invention

[0003] This utility model provides a mobile power frequency withstand voltage test device. During testing, the device can be quickly deployed using a telescopic track, ensuring a safe distance between test components and eliminating the need for frequent wiring connections between them. When moving or storing, the track retracts, allowing the test components to be placed in a concentrated manner, saving space and facilitating transportation.

[0004] The present invention adopts the following technical solution:

[0005] A mobile power frequency withstand voltage testing device, characterized in that: it includes a load-bearing platform and a telescopic platform. The load-bearing platform has two parallel telescopic tracks at its bottom. Each telescopic track is a hollow sleeve type, comprising a fixed sleeve and a telescopic sleeve inserted into the fixed sleeve. The fixed sleeve is fixedly connected to the load-bearing platform. One end of the telescopic sleeve extends out of the bottom of the load-bearing platform and is fixedly connected to the telescopic platform. An electric push rod is provided between the two telescopic tracks at the bottom of the load-bearing platform. The top end of the telescopic rod of the electric push rod is fixedly connected to the telescopic platform. The electric push rod is used to move the telescopic platform away from or towards the load-bearing platform. A test transformer, a test voltage divider, and a test protection resistor are installed above the load-bearing platform. The test voltage divider is connected between the test transformer and the test protection resistor, and the test protection resistor is equipped with a foldable grounding rod. A test chamber is installed above the telescopic platform, and a power frequency withstand voltage tester is installed inside the test chamber. The load-bearing platform is equipped with movable wheels at the bottom, and the telescopic platform is equipped with electric casters at the bottom. An electric handle is installed at the top of the test chamber, and an extension rod is installed at the bottom of the electric handle. The extension rod passes downward through the test chamber and the telescopic platform and connects to the electric casters. A foldable footboard is installed at the front end of the telescopic platform.

[0006] Furthermore, the telescopic platform has foldable casters on both sides of the electric casters at its bottom.

[0007] Furthermore, both the fixed sleeve and the telescopic sleeve of the telescopic track are hollow sleeves, and the hollow sleeves are provided with circuit grooves inside, through which the connecting cable between the power frequency withstand voltage tester and the test transformer passes.

[0008] This utility model has the following beneficial effects:

[0009] This invention connects the load-bearing platform and the telescopic platform using a telescopic track. During testing, an electric push rod moves the telescopic platform closer to or further from the load-bearing platform, allowing for rapid deployment or retraction of the equipment. This achieves electric adjustment of the safe testing distance between the power frequency withstand voltage tester and the test transformer, eliminating the need for wiring connections between components for each test. This avoids the safety hazards associated with frequent wiring operations, improves testing efficiency, saves labor, and ensures worker safety. When moving or storing, the telescopic track retracts, combining the load-bearing platform and the telescopic platform, allowing for centralized placement of test components, saving storage space, and facilitating convenient transportation.

However, the accompanying drawings are for reference and illustration only and are not intended to limit this utility model.

[0015] Example: Please refer to Figures 1 to 3 As shown, a mobile power frequency withstand voltage testing device includes a load-bearing platform 1 and a telescopic platform 2. The load-bearing platform 1 has two parallel telescopic tracks 3 at its bottom. Each telescopic track 3 is a hollow sleeve type, including a fixed sleeve and a telescopic sleeve inserted into the fixed sleeve. The fixed sleeve is fixedly connected to the load-bearing platform 1, and one end of the telescopic sleeve extends out of the bottom of the load-bearing platform and is fixedly connected to the telescopic platform 2. An electric push rod 4 is located between the two telescopic tracks 3 at the bottom of the load-bearing platform 1. The top end of the telescopic rod of the electric push rod 4 is fixedly connected to the telescopic platform 2. The electric push rod is used to move the telescopic platform away from or closer to the load-bearing platform. Above the load-bearing platform 1 is a... The test platform includes a test transformer 5, a test voltage divider 6, and a test protection resistor 7. The test voltage divider 6 is connected between the test transformer 5 and the test protection resistor 7. The test protection resistor 7 is equipped with a foldable grounding rod 8. A test chamber 9 is located above the telescopic platform, and a power frequency withstand voltage tester 10 is located inside the test chamber. The load-bearing platform 1 has movable wheels 11 at its bottom, and the telescopic platform 2 has electric casters 12 at its bottom. The test chamber 9 has an electric handle 13 at its top, and an extension rod at its bottom. The extension rod passes downward through the test chamber and the telescopic platform and connects to the electric casters 12. The telescopic platform 2 has a foldable passenger footboard 14 at its front end. Foldable casters 15 are located on both sides of the electric casters 12 at the bottom of the telescopic platform 2. The telescopic track is a hollow sleeve type telescopic track, and the hollow sleeve has a circuit groove (not shown) inside. The connecting cable between the power frequency withstand voltage tester and the test transformer passes through the circuit groove inside the telescopic track.

[0016] The working principle of this utility model is as follows: Before preparing for the test, the foldable grounding rod 8 of the test protection resistor 7 is lowered to make the whole equipment grounded. Then, the electric push rod 4 at the bottom of the load platform 1 drives the telescopic platform 2 to extend outward along the telescopic track 3. The telescopic platform 2 drives the power frequency withstand voltage tester 10 away from the load platform 1, so that the power frequency withstand voltage tester 10 and the test transformer 5 maintain a sufficient safe test distance, and the test can be started. The electric push rod 4 and the power frequency withstand voltage tester 10 share the same external power supply and controller.

[0017] Before moving the platform, first combine the load-bearing platform 1 and the telescopic platform 2 along the telescopic track 3, then open the personnel platform 14. An operator stands on the personnel platform 14 and controls the electric handle to drive the entire platform forward using the bottom electric casters 12. The electric casters 12 can be powered by a rechargeable battery and are commercially available products. The direction of travel can be changed by controlling the bottom electric casters 12 via the electric handle 13. After moving the platform, retract the personnel platform 14. If the electric casters 12 malfunction, the folding casters 15 can be opened to replace them for emergency use, allowing the platform to be moved manually.
