Talk about the principle and function of variable frequency series resonant voltage withstand test equipment


Variable frequency series resonant withstand voltage test equipment is mainly used for AC withstand voltage test of cross-linked cable, hydraulic generator, main transformer, bus, GIS and so on. It is composed of variable frequency control power supply, excitation transformer, reactor, capacitor voltage divider and compensation capacitor. Because the voltage, waveform and frequency and the electric field state inside the insulation of the tested object are consistent with the actual operation, and the test voltage is higher than the actual operation voltage, therefore, the insulation strength is strict, direct and effective method.

Overview of Operation Test of Electrical High Voltage Test Equipment


In addition to the long-term operation under rated voltage, the power generation, supply and consumption equipment in the power system must have the insulation strength under overvoltage. Overvoltage refers to the voltage rise that exceeds the normal operating voltage, which is the damage of electrical equipment or protective equipment. In all kinds of power system accidents, a large part is caused by the insulation damage of equipment caused by overvoltage. When the insulation is defective, if it is not found and eliminated in time, it will eventually lead to equipment damage and power failure.

Characteristics of gas-filled test transformer


The inflatable test transformer is a brand-new test equipment, which adopts the characteristics of GIS combination cabinet, with small quality, light volume and beautiful appearance. Its technical indicators have reached the standard requirements, high insulation strength, compressive strength for the same pressure of nitrogen 2.5 times, 2.5 times the breakdown voltage of air. It is equal to the breakdown voltage of oil at 0.25MPa and twice the breakdown voltage of oil at 0.45MPa.
