Working Principle

（1Relay: The electrical control220VIs the power connected to the regulator, thereby controlling the engagement or disconnection of the high-voltage output?

（2Voltage Regulator: Primarily composed of a voltage regulator, the change in voltage is achieved through the adjustment of this regulator.

（3High-voltage Transformer: By adjusting the voltage regulator's knob, the input voltage of the high-voltage transformer is increased, from which high voltage is obtained. Direct AC voltage output.

（4The Current Detector: This section of the circuit converts the current flowing through the component into voltage, compares it with the reference voltage, and then outputs a detection signal to the controller.

（5The controller: controls whether the relay is connected and the alarm circuit is triggered based on signals from the current detector, start/stop button, and timer.

（6The timer: After pressing the start button, the high voltage is connected, and the timer begins to countdown. Upon reaching the set time, the high voltage is disconnected through the control circuit, thereby achieving the purpose of timed testing.

（7Alarm: During the testing process,When the leakage current exceeds the set leakage current preset,The driver block powers the buzzer and ultra-leakage lamp to emit an audio-visual alarm.,Simultaneously, it automatically cuts off high voltage.
