Series Resonance Test Equipment
Darui Electric recommends for you:
The series resonance principle is a product. The variable frequency series resonance test device applies the series resonance principle, uses an excitation transformer to excite the series resonance circuit, adjusts the output frequency of the variable frequency controller, so that the loop inductance L and the test product C resonate in series, and the resonance voltage is the voltage applied to the test product..
The variable frequency resonance test device is widely used in electric power, metallurgy, petroleum, chemical and other industries, and is suitable for handover and preventive tests of capacitive test products with large capacity and high voltage.
Test Objects
1. AC withstand voltage test of 6kV-500kV high-voltage cross-linked cables
2. AC withstand voltage test of generators
3. AC withstand voltage test of GIS and SF6 switches
4. Power frequency withstand voltage test of 6kV-500kV transformers
5. AC withstand voltage test of other high-voltage power equipment such as busbars, bushings, and instrument transformers.
Selection Basis
The variable frequency series resonance test equipment is different from general-purpose test instruments. The biggest feature is that the same set of equipment can be used for AC withstand voltage tests of different electrical equipment such as cross-linked cables, transformers, GIS, motors and generators. In addition to the series of typical commonly used models provided in this selection catalog for users to choose, it is usually necessary to design the configuration scheme according to the user's test product range and test requirements to meet the test requirements of different regions, different users, and different test products.
