Product DescriptionSF6 Gas Insulated AC Test TransformersDescriptionSF6 gas insulated HV AC test systems are widely used for factory testing of GIS and their metal-clad components, especially instrument transformers, and for on-site testing as well. They are metal-clad encapsulated, can be directly flanged to test object, so test system and test object are fully encapsulated. This allows a space saving test setup without safety clearances between test system or test object and walls or other objects. The test system and test object become a closed system with a low PD background noise level when directly flanged. This feature makes the model ideally suited for sensitive PD measurements. In factory, these systems allow to test sub-assemblies and components directly in the manufacturing line, thus avoiding transportation to a central test facility, and extra handling. Furthermore, they can also be used for AC voltage test of other HV apparatus when equipped with output bushing.ApplicationHVAC transformer based GlS test systems are mainly used for: 1. Factory testing of small complete GlS, such as spacers, electrodes, instrument transformers, disconnectors, circuit breakers, and small complete GlS systems.2. Factory testing of voltage with GlS (the test system can be provided with a power supply for higher frequencies.3. Test of accessories, e.g. SF6 to air or SF6 to oil bushings.4. Research, development and education.The test systems can be used as voltage source for PD measurement. They are directly fanged to the test object, so that test system and test object are fully encapsulated. This allows a space saving test setup without safety clearances between test system or test object and walls or ceiling.Features1. Long running time, breaking the bottleneck of short-term running of domestic and foreign products for 30 minutes, and continuous running.2. The partial discharge is small, and the rated voltage is < l pc.3. The rated output voltage is 1500kV, with high voltage level.4. The running current is large, and the rated output can be 5A.5. It can save space and distance, and it only needs to be matched with the mouth of the sample.6. Reduce the one-time investment of the factory without shielding hall.7.According to the needs of users, the shell can be made of aluminum or iron.Main ConfigurationsPrimary power switchgearDouble shielded isolation transformer200kVA 0.415kV 0~3.3kV Voltage regulatorSecondary power switchgear200kVA 3kV Power noise filterOver-voltage fast protect device800kVar 3kV Compensation reactor800kVA 800kV Encapsulated SF6 test transformer800kV 1A 3kΩ Protect resistor500pF 800kVCapacitor dividerComputer control and measure systemPower frequency peak value voltmeterProducts Parameters1ModelYDQW2Rated voltage300 to 1250kV3Rated current0.1 to 5A4ControlManual & Automatic Computer controlReferenceCompany ProfileXiamen Fivestar Electric Test Equipment Co., Ltd.
