Product Overview
Executive Standard: DL/T848-2004
The induced withstand voltage test for transformers and instrument transformers is an important test to ensure that transformer quality meets national standards. The longitudinal insulation induced withstand voltage test for inter-turn, inter-layer, inter-section, and phase-to-phase insulation of transformer windings is a key item in transformer insulation testing. Due to the特殊性 of the longitudinal insulation test, it is necessary to apply a frequency multiplier power supply device to increase the test voltage between windings, thereby achieving the purpose of the withstand voltage test.
The GDSF-81 triple frequency generator is designed and manufactured by Guodian Xigao to meet the above requirements. It has been proven by extensive user experience: it is simple to operate, reliable in performance, and can effectively meet the needs of transformer and instrument transformer induced withstand voltage tests.
Product Features
- Adopts a three-phase five-limb structure, with simple process, and reduces the internal impedance and leakage flux loss of the transformer body, improving the efficiency of the generator.
- Weight and volume are smaller than traditional three single-phase transformer groups, and it is equipped with a control box of corresponding capacity, making it convenient for field use.
- This product can be used as a induced withstand voltage test for transformers and electrical equipment of corresponding capacity, or as a 150Hz power supply for short-term operation.
