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.

VI. Functions description

Remote control and indication function for the iron-core gap of reactor:The gap sensor is installed in the reactor, which directly reads the iron-core gap on the console to guide operation. The gap limiting switch and indicator are also installed.
Auto step down function when withstanding time is up:Withstanding timing adopts digimatic timer. When withstanding time is up, the system will auto step down.
Zero position close, zero start step up function:With zero limiting function. If the voltage regulator is not at zero position, then the HV output button cannot be closed, assuring the system step up from zero.
Over current protection:The system is with over current relay, which is of high anti interference, fast action, protection test object against over-current damage.
Over voltage and test object flash-over protection functions:This system takes electronic over voltage and flash-over protection board, protects test object against over voltage and flash-over. It is fast, stable and reliable, overcoming the instability, large discreteness and inconvenient adjustment of sphere-gap protection voltage. The setting of over voltage protection is manual adjustment, digital display, which is direct, convenient and accurate. The flash-over protection samples the accident variance of discharging signal falling delay, compares it with basic signal and determines. It is of high accuracy, avoiding possible mistake movement by accident variance of rising delay.
Real-time monitor function for test data:It is able to monitor HV side voltage, current and LV side voltage, current, which is more direct viewing the test status.
Digital display of circuit resonance and locking function when it is not of resonance and step up:
It can directly display the resonance status of the system by power factor. If the system is not at the resonant point, it must press close button to step up. When the system is adjusted to resonance, release the close button, click on the step up/down button to step up or step down.
Emergency stop :“Step on” emergency brake switch. Once there is abnormal conditions during test, step on this switch, the main power will be cut off right away to protect the safety of the testing personnel and the equipment.
