1. The main feature of the high-voltage switch tester is that it uses Chinese prompts to operate in a human-machine dialogue manner, displays results in Chinese and prints them out. It has the advantages of intelligence, multiple functions, accurate data, strong anti-interference, simple operation, small size, light weight, and beautiful appearance. It is suitable for dynamic characteristic testing of various indoor and outdoor low-oil, multi-oil switches, vacuum switches, and SF6 switches. Series resonance power supply products are mostly high-voltage test equipment and are essential equipment for high-voltage test professionals. Before use, the instruction manual should be carefully read, and training should be conducted through repeated operations.
2. The number of operators must not be less than 2. During use, the safety operation regulations for high-voltage tests of the unit should be strictly followed.
3. In order to ensure the safety and correctness of the test, in addition to being familiar with the specifications of this product, the test operation must strictly follow the relevant national standards and procedures. The switch tester can also flexibly select external operating power or external synchronous triggering. Large-screen LCD display, with preset typical switch speed definitions; can switch time waveform diagram display of 1 channel closing/opening command, 12 channels of time jumps; S-T graphic display of closing/opening motion curves, with dynamic analysis and calculation; V-S curve for intuitive observation of motion speed; I-T curve to observe the action process of the electromagnet.
4. Each connecting wire must not be wrongly connected, especially the grounding wire must not be wrongly connected. Otherwise, damage to the test equipment may occur.
5. When using this device, the output voltage is high voltage or ultra-high voltage, and reliable grounding must be ensured, and attention should be paid to safe operating distances. The withstand voltage tester can also be called electrical insulation strength tester, dielectric strength tester, etc. according to its function. Its working principle is to apply a voltage higher than the normal working voltage to the insulation of the tested equipment for a specified period of time. If the voltage applied only produces a small leakage current, the insulation is good. The test system consists of three modules: programmable power supply module, signal acquisition and conditioning module, and computer control system.
Series resonance is widely used in electric power, metallurgy, petroleum, chemical and other industries, and is suitable for large-capacity, switching and preventive tests of high-voltage capacitive test samples. The portable variable frequency series resonance device is mainly used in the following aspects:
AC withstand voltage test of 6kV-500kV high-voltage cross-linked cables, AC withstand voltage test of generators, AC withstand voltage test of high-voltage cross-linked cables, AC withstand voltage test of high-voltage cross-linked cables, AC withstand voltage test of high-voltage cross-linked cables, AC withstand voltage test of high-voltage cross-linked cables, AC withstand voltage test of generators. AC withstand voltage test of GIS and SF6 switches, power frequency withstand voltage test of 6kV-500kV transformers, withstand voltage test of busbars and other high-voltage power equipment, AC withstand voltage test of bushings and transformers.
