HMCXL series adjustable power frequency resonant tester

adjustable power frequency resonant tester meet the needs of large capacity and high voltage (ultra high voltage) to test electrical equipment

◆ Small size, light weight,
◆ easy installation and transportation, simple wiring,
◆ very suitable for on-site personnel operation.

Brief Introduction

In order to meet the needs of large capacity and high voltage (ultra high voltage) to test electrical equipment, the booster device using a series resonant principle, with adjustable reactor and test equipment (capacitive) or the capacitance compensation capacitor to form a resonant matching. Thus, the test power supply only takes the active component, which is only 1/Q times of the required capacity of the test, and the capacity and weight of the test equipment are greatly reduced. It is an ideal high voltage source.

The Main Function Of Adjustable resonant test device:

(1) Telemetry function of reactor core gap:

The device is provided with a gap sensor on the reactor, and the gap of the iron core can be directly read out on the console to guide the operation, and a gap limit switch and an indication are additionally arranged.

(2) Withstand time to automatic step-down function:

Digital timer is used for withstand timing and when reach to withstanf voltage time, the system will automatically step-down

(3) Zero turn on and zero rise:

Zero limit function, if the voltage regulator is not zero, the high voltage output button can not close, and ensure that the system is from zero to step up.

(4) Over current protection function:

The system is equipped with electromagnetic overcurrent relay, this relay anti-interference ability, quick action, to avoid test products not flow damage.

(5) Overvoltage and the flashover protection function of the tested products:

The utility model is provided with an electronic overvoltage flashover protective plate to avoid the damage of the test product not subjected to pressure and flashover, and the action is rapid.

(6) Real-time monitoring function of each test data:

The voltage, current and the voltage and current on the low voltage side can be monitored, so that the test can be understood more intuitively.
