Description

Technical Field

[0001] This utility model belongs to the field of testing equipment, and specifically relates to a multi-winding transformer interlayer withstand voltage tester. Background Technology

[0002] Power module withstand voltage testers are specialized devices used to test the insulation performance of power modules. However, current power module withstand voltage testers have certain limitations in their functional scope. As power module applications become increasingly diverse, in harsh conditions such as high altitudes and high vibration environments, power modules not only need to withstand voltage tests, but the deformation of their internal structure due to pressure changes can also affect their insulation performance. However, existing testers only focus on voltage testing and cannot simulate these pressure factors, resulting in a lack of assessment of the module's insulation reliability under complex real-world conditions. This is mainly because traditional tester designs rely more on conventional electrical safety standards and do not fully consider the comprehensive impact of complex environmental factors on power modules. To address this, common practices include using additional equipment to simulate pressure environments after voltage testing, or placing the module in a real, complex environment for extended periods of trial operation. However, the former increases testing steps and time costs, and the connection between different devices can easily introduce errors. Therefore, a new structure is needed to solve these technical problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-winding transformer interlayer withstand voltage tester to solve the problems mentioned in the background technology.

[0005] In a preferred embodiment, an electric push rod is installed on the right edge of the upper surface of the base box, and a cylinder is installed on the left edge of the upper surface of the base box. The cylinder and the electric push rod are collinearly aligned, and a gap is provided between the cylinder and the electric push rod.

[0007] In a preferred embodiment, a housing is installed on the left side surface of the base box and the control cabinet, the height of the housing matches the height of the control cabinet, and a door is hinged to the upper edge of the front surface of the housing.

[0008] In a preferred embodiment, the interior of the enclosure is provided with a receiving cavity, the surface of the enclosure door is equipped with a handle, and the voltage component includes a display panel and a voltage generator.

[0009] In a preferred embodiment, two voltage generators are symmetrically installed at the bottom of the internal cavity of the housing, with a gap between the two voltage generators, and a display panel for displaying data is installed on the rear surface of the internal cavity of the housing.

[0020] Please see Figures 1 to 3 As the first embodiment of this utility model: a multi-winding transformer interlayer withstand voltage tester, comprising: test component one and test component two, test component one for pressure testing is installed on the upper surface of the base box 100, test component two for voltage testing is installed on the front surface of the box 300, control cabinet 110 for control is installed on the rear surface of the base box 100, control board 120 for controlling test component one and test component two is installed on the front surface of control cabinet 110, test component one includes an electric push rod 200 and a cylinder 210 for pressure testing of the power module, and test component two includes a voltage component for voltage testing of the power module;

[0021] An electric push rod 200 is installed on the right edge of the upper surface of the base box 100, and a cylinder 210 is installed on the left edge of the upper surface of the base box 100. The cylinder 210 and the electric push rod 200 are aligned with the central axis of the cylinder 210 and the electric push rod 200, and a gap is provided between the cylinder 210 and the electric push rod 200.

[0022] A control cabinet 110 is installed on the rear surface of the base box 100. A heat dissipation hole 111 is installed on the right side surface of the control cabinet 110. A control board 120 is installed on the front surface of the control cabinet 110. A control board 120 for controlling test component two is installed on the right side surface of the box 300.

[0023] In use, the user first places the power module to be tested on the upper surface of the base box 100, and then positions the power module between the cylinder 210 and the electric push rod 200. At this time, the user can start the electric push rod 200 and the cylinder 210 through the control cabinet 110 and the control board 120, so that the electric push rod 200 and the cylinder 210 squeeze the power module, thereby performing a pressure resistance test on the power module. The upper layout facilitates the operator to quickly place and fix the power module, and then perform a pressure test on the power module. It conforms to the ergonomic design, which can reduce operator fatigue and improve testing efficiency.

[0024] Please see Figures 1 to 3 As a second embodiment of the present utility model: based on the description in the above embodiments, further, a box 300 is installed on the left side surface of the base box 100 and the control cabinet 110, the height of the box 300 is matched with the height of the control cabinet 110, and a box door 310 is hinged to the upper edge of the front side surface of the box 300.

[0027] During use, the voltage generator 340 is a multi-winding transformer that can generate voltage to perform withstand voltage tests on the power module (the voltage generator 340 is existing technology, and its specific working principle and structure will not be elaborated here). After the user completes the withstand voltage test of the power module, the user can open the door 310 of the enclosure 300, place the power module inside the receiving cavity of the enclosure 300, and then connect the power module to the voltage generator 340 through wires (the specific power connection principle and circuit can be selected according to the actual situation, and will not be elaborated here).

After the test is completed, the user can open the enclosure door 310 and view the test data through the display panel 330. Due to the spatial separation layout of the dual components during use, signal interference is reduced, making the pressure test and voltage test process more seamless. It can efficiently complete the fixing and power-on test of the power module, and facilitate the simultaneous analysis of pressure and voltage data, significantly improving the accuracy, efficiency and safety of the overall test.
