Description

Technical Field

[0001] The utility model relates to the technical field of high - voltage test benches, and specifically relates to a high - voltage test bench. Background Art

[0002] A high - voltage test bench is a device used for high - voltage performance testing and detection of electrical equipment, electronic components, insulating materials, etc. It usually consists of a high - voltage generator, a measurement system, a control system, and a safety protection device, etc. The high - voltage generator can generate the required high voltage. The measurement system is used to monitor and record parameters such as voltage, current, and power. The control system realizes the control and regulation of the test process, while the safety protection device ensures the safety of operators and equipment.

[0003] The existing equipment has certain disadvantages:

[0004] 1. The equipment is too large in volume, occupying too much production space and increasing production costs;

[0005] 2. The high - voltage generator is installed at the bottom of the installation positioning plate, making fault repair troublesome, requiring more time for repair and having low efficiency;

[0006] 3. The test lead cover is extremely heavy, and only male employees with great strength can operate the manual switch of the test lead cover, increasing production costs;

[0007] 4. The ball tube installation basket is connected and conducts electricity with the installation positioning plate through a rubber connector. Placing and removing the ball tube installation basket is laborious, and it is easy to cause the internal insulating oil of the test box to splash outside, which may spatter into the eyes of the operator, posing a safety production risk and affecting production costs.

[0008] Therefore, the utility model provides a high - voltage test bench to solve the above problems. Utility Model Content

[0009] Aiming at the deficiencies of the prior art, the utility model provides a high - voltage test bench to solve the above problems.

[0010] To achieve the above objectives, the utility model is realized through the following technical solutions: A high - voltage test bench includes a frame. A control mechanism is arranged at the top of the frame. An upper platform is fixedly installed inside the frame. A test oil tank is fixedly installed at the top of the upper platform. A test lead cover is movably installed at the top of the test oil tank. The test lead cover is hinged inside the frame. A counterweight block is fixedly installed on the back of the test lead cover. The hinge between the test lead cover and the frame is located between the counterweight block and the front end of the test lead cover. An electrical control box is fixedly installed on the back of the frame.

[0011] Preferably, an installation positioning bracket is fixedly installed on the inner bottom plate of the test oil tank, and a tube basket for installing a tube is fixedly installed at the front end of the top of the installation positioning bracket.

[0012] Preferably, a high-voltage generator placement area is fixedly installed at the rear end of the top of the installation positioning bracket, which is convenient for the removal and installation of the high-voltage generator.

[0013] Preferably, a test tube is fixedly installed inside the tube basket for installing a tube, a detector is fixedly installed below the test oil tank, a lower platform is fixedly installed at the bottom of the frame, and the detector is fixedly installed at the top of the lower platform.

[0014] Preferably, the tube basket for installing a tube, the detector, the test tube, and the installation positioning bracket are all on the same vertical line.

[0015] Preferably, the control mechanism is composed of a computer and a display.

[0016] Advantageous effects

[0017] The utility model provides a high-voltage test bench. Compared with the prior art, the following advantageous effects are achieved:

[0018] 1. For this high-voltage test bench, by placing the detector below the test tube, the high-voltage generator can be placed behind the test basket, and the dust-proof plate above the high-voltage generator placement area is designed to be self-weight placed and positioned, which is convenient for the disassembly and installation of the high-voltage generator during maintenance, reduces the maintenance time, and improves the production efficiency.

[0019] 2. For this high-voltage test bench, the electrical connection between the tube basket for installing a tube and the installation bracket uses a spring telescopic contact structure. During the lifting and placement of the tube basket for installing a tube, only two pairs of springs are used for telescopic force, unlike the mechanical deformation friction contact of a rubber connector, which is more labor-saving and quieter, and will not cause the sputtering of insulating oil, thus reducing a safety production risk point and lowering the safety production risk cost.

[0030] Meanwhile, the content not described in detail in this specification belongs to the well-known prior art in the art.

[0031] Working principle: 1. By optimizing the electrical control circuit, reducing the size of the electrical control, and reasonably arranging the installation structure of the computer control system, the size of the equipment is significantly reduced. Without a separate electrical control cabinet, the production space occupied by the equipment is reduced, and the unit area utilization efficiency of the production workshop is improved;
