380V AC Resonant Test System Power Frequency Resonant Intelligent Control Unit

Power Frequency AC Resonant Withstand Voltage Test Set , Power Frequency Resonant Intelligent Control Unit

I. Product Description :

CHXT (L) series power frequency resonant intelligent control system, based on the manual control system, carried out by the IPC with PLC control, set the operation, control, monitoring and protection in one of the intelligent control system.

Combined with power frequency series resonant system, this system can do fully automatic completion AC voltage withstand test to various generating units, Assembling Capacitor, power cables and GIS, CT, insulators, insulation tools, busbar and so on. in the power equipment manufacturers

II. Appication and usage

• The measurement and control unit for Power Frequency AC resonant withstand voltage test circuit.
• Replace the old traditional console to increase the efficiency of high-voltage test and enhance monitoring and protection during resonant withstand voltage testing.

III. Main Components of the unit:

• Intelligent Resonance Control console
• Electric voltage regulator cabinet
• PLC computer (built-in designed or external layout designed ,optional)
• Connection cables group
• External alarm lights

IV. Main functions:

1. Perfect manipulative function:

• Programmable auto-test function
• Auto resonant-point searching
• Resonant-point tracing function during step-up
• HV-limiting function
• Tracing function during voltage withstand
• Manual intervention at any time during auto test
• Variable control of step-up speed with the speed range of 2~5Kv/s

2. Date measurement and display function

Display items:

① Power voltage, current；

② Output voltage, current of voltage regulation；

③Voltage of HV side；

④ Clearance of iron core；

⑤ Q Value；

⑥ COSø Value Harmonic degree；

⑦u→t curve.

3. Self-checking for real-status and display function

• Displaying its own manipulation is to facilitate the user to monitor. During the test, it is automatically monitored the run situation by the PLC, and once any fault it stops for processing.

4. Protective function

• Fiber-optical communication isolation
• Flashover protection
• Over-voltage protection
• HV sampling lost protection
• HV limiting protection
• Emergency brake protection

5. Data management function

• Database in the system can retain various historical test data. Flexible and simple search facilitate users to judge the status of the test object on history data and create the file of test object.
