Characteristics of gas-filled test transformer
【overview】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.
Today to introduce a new type of inflatable 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. The technical requirements of the product are in full compliance with the "ZBK-41006-89" standard, it is oil-immersed light test transformer replacement products. The product has the characteristics of small size, light weight, not affected by climate change, small corona, no need for static on-site handling, long service life, and maintenance-free. It is suitable for power systems, industrial and mining enterprises, scientific research departments and other high-voltage electrical equipment, electrical components, insulation materials for power frequency or DC high voltage insulation strength test.
This inflatable test transformer is a small size, light weight, small corona, but also has a super compressive strength of high-voltage equipment, quick try it!
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.
