Description

Technical Field

[0001] The utility model relates to the field of teaching and training equipment, in particular to an insulation withstand voltage safety test equipment for teaching. Background Art

[0002] The insulation withstand voltage safety tester is a device used to evaluate the insulation performance and withstand voltage capability of photovoltaic modules. Its basic principle is to detect the insulation strength and withstand voltage level of photovoltaic modules by applying a certain high voltage. When the applied voltage exceeds the insulation strength of the photovoltaic module, the current will leak. By measuring the magnitude of the leakage current, the insulation performance of the photovoltaic module can be evaluated. The insulation withstand voltage safety tester is widely used in the production, quality control and safety certification of photovoltaic modules. In the production process, by conducting insulation withstand voltage tests on photovoltaic modules, potential quality problems can be discovered in time to ensure that the products meet relevant standards and specifications. In terms of safety certification, the insulation withstand voltage safety tester is one of the important bases for obtaining safety certification, which is of great significance for ensuring the safety and stability of photovoltaic modules in practical applications. Therefore, in photovoltaic professional education, practical training around insulation withstand voltage safety testing is particularly important.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the following further describes how the present invention is implemented in conjunction with the accompanying drawings and specific implementation methods.

[0019] Reference Figure 1-Figure 2 As shown, the utility model provides an insulation withstand voltage safety test equipment for teaching, including a shell 1, a tester body 2 and a test cabin 3; the shell 1 is made of insulating material, the tester body 2 is located at the upper part of the shell 1, and the operation panel of the tester body 2 is located on the surface of the shell 1; the test cabin 3 is located at the lower part of the shell 1, and the test cabin 3 is used to place the components to be tested; the surface of the shell 1 is also provided with a cabin door 4 corresponding to the test cabin 3, the cabin door 4 is equipped with a magnetic switch 5, and the magnetic switch 5 is connected to the control interface of the tester body 2, and the magnetic switch 5 is used to provide the tester body 2 with a switch signal of the cabin door 4.

[0020] Preferably, an insulating pad is provided at the bottom of the test chamber 3, and the component to be tested is placed above the insulating pad.

[0021] Preferably, the hatch 4 is a double-opening door, and the hatch 4 is made of an insulating transparent acrylic material, which can play an insulating role and at the same time can conveniently and clearly observe the status of the component to be tested in the test cabin 3.

[0022] It can be seen that the outer shell 1 and the hatch 4 are made of insulating materials as a whole, so as to enclose the tester body 2 and the internal components to be tested in a completely insulating environment, thereby ensuring the test accuracy and improving the safety.

[0023] The tester body 2 may be an industrial insulation withstand voltage tester, and parameters may be set and test results may be displayed through an operation panel. During testing, its high-voltage circuit is connected to the component to be tested through the inside of the device body.

[0024] The magnetic switch 5 is used in conjunction with the hatch 4 to provide safety protection. The existing computer program can be configured to limit the output voltage of the tester body 2 to a preset safety value and prohibit high voltage output when the tester body 2 senses that the hatch 4 is not closed through the magnetic switch 5, thereby ensuring the safety of the user.

[0025] In summary, the teaching insulation withstand voltage safety test equipment provided by the utility model greatly improves the operational safety while providing the test function, and provides users with a safe and efficient learning platform, which is especially suitable for students majoring in photovoltaics.
