Description

Technical Field

[0001] The utility model relates to the technical field of generator side-view instruments, and more specifically to a generator withstand voltage test device. Background Art

[0002] Generators are devices that convert mechanical energy into electrical energy. They are installed in power plants. Generators are divided into DC generators and AC generators according to the power supply used. Most of the generators in the power system are AC motors, and they are synchronous motors (the motor rotor and stator rotate at the same speed). The withstand voltage tester can be called an electrical insulation strength tester, a dielectric strength tester, etc. according to its function. Its working principle is: a voltage higher than normal operation is applied to the insulator of the device under test for a specified period of time. The voltage applied to it will only produce a small leakage current, and the insulation is good. The test system consists of three modules: a programmable power supply module, a signal acquisition and conditioning module, and a computer control system. Select two indicators of the withstand voltage tester: the maximum output voltage value and the maximum alarm current value.

[0003] After searching, the existing patent number CN217561641U is a generator withstand voltage test device, which includes a base, an equipment box, a display panel, wires, a plug and a test socket, and the equipment box is connected to the surface of the base, the display panel is installed on the side of the equipment box, the test socket is set on the side of the equipment box, the plug is plugged into the inside of the test socket, and the wire is connected to one end of the plug. The generator withstand voltage test device also includes: a limit assembly, which is set on the equipment box and is used to limit the position of the plug. The utility model can conveniently limit the position of the plug after the plug is inserted into the test socket by setting elastic parts, mounting parts, limit parts, pressure parts, finger rings, slide rails and sliders, so that the plug can maintain a stable plug-in posture inside the test socket, thereby preventing the plug and wire from loosening or falling off inside the test socket when the generator withstand voltage test is performed, thereby affecting the test effect.

[0004] The withstand voltage tester is placed on the test bench to test the generator. However, during the installation or testing of the tester, the tester will be moved back and forth and the installation angle will be adjusted according to the needs of use. The bottom of the tester is pushed and pulled directly relative to the test bench, which not only has a large friction resistance, but also easily causes wear of the instrument. In addition, during the pushing and pulling process, the detection line plugged into the detection end of the instrument is easy to loosen and fall off, reducing the use effect. Therefore, we proposed a generator withstand voltage test device to solve the above problems. Utility Model Content
