1200KV 120kJ Impulse voltage generator display video

The main interface of startup is shown in Figure 1.

Button Description:

Start: Press the start button, the action of the main contactor and the ground switch in the control cabinet will turn red and the word "disconnect" will be displayed. After pressing the red button to disconnect, the contactor will disconnect, and the start button and the ground button will both return to the starting state.

Start test: When the start button turns red and the disconnect button is turned, the button can only be operated, otherwise it cannot be operated.Press the start test button, the body starts to charge, and the word turns red. After pressing the button to stop, the charging stops.

Manual trigger: After pressing the manual trigger button, the igniter will ignite the body ball to discharge.

Automatic trigger alarm: When this option is selected, charging can be realized. When the set charging voltage is reached, the system will automatically ring the bell for ignition and discharge.

Alarm: After pressing the alarm button, the alarm will ring until the button is released.

Primary side current of charging transformer: CT of primary measuring equipment is located in the control cabinet.This current is the original side current of the charging transformer.In the setting screen, set the current overcurrent limit value of the original side of the transformer. If it exceeds this value, the main contactor will be disconnected.

Original side voltage of charging transformer: the primary measuring device PT is located in the control cabinet.This voltage is the original voltage of the charging transformer.In the setting screen, set the limit value of voltage overvoltage on the original side of the transformer. If the value exceeds the limit value, the main contactor will be disconnected.

Section 1 Charging Voltage: Measure the resistance voltage divider of the primary equipment.This voltage is the first charging voltage of the body.In the setting screen, set the limit value of charging voltage overvoltage. If the limit value exceeds this value, the main contactor will be disconnected.

Charging voltage positive and negative polarity selection: according to the test needs to choose the corresponding polarity, transmission electric machine will automatically turn to the polarity limit.

Ball distance of body: in the case of running full lightning wave for the test product, the ball distance of body shall be adjusted according to the voltage level of the test product. It shall be manually adjusted by points and buttons.

Counter reset: After manually pressing down, the value of the counter will be reset automatically.

Setting charging voltage: voltage value of charging voltage, rating of automatic charging voltage.

Set charging interval: Set the value of automatic test interval. In the case of automatic continuous discharge, set the interval between two tests.

2.The setting interface is shown in Figure 2

 Soft overvoltage V1 limit of original side of charging transformer: When the voltage value of original side of transformer is greater than the corresponding setting value, the main contactor will be disconnected.

 Soft overcurrent A1 of the original side of the charging transformer: When the current value of the original side of the transformer is greater than the corresponding setting value, the main contactor will be disconnected.

 Single maximum charging voltage limit: When the charging voltage value is greater than the corresponding setting value, the main contactor will be disconnected.

 Body ball distance setting: Set the ball distance according to experience. Click the automatic ball distance on the main interface, and it will automatically adjust to the corresponding distance.

 Partial voltage ratio: The ratio calculated according to the resistance of the voltage divider.Do not modify the partial pressure ratio setting

 Set charging times: the number of times to be set in the case of automatic test.

 Maximum and minimum value of ball distance: The maximum and minimum value of ball distance are set according to the pull-up potentiometer of the body ball distance.

 Trouble indicator: any trouble, the corresponding light above will flash.Click alarm Reset and the alarm is cancelled.

 When the weather is very wet, there will be a strong leakage current or a strong surface discharge on the insulating surface of the charging equipment and the generator itself, so the impulse voltage generator is not suitable for use at this time.

 Before using the impulse voltage generator, should carefully clean the surface of dust, keep clean and dry.When using impulse voltage generator, if abnormal phenomenon is found, the test should be stopped for inspection.

 If it is found that the ignition ball, wave clipping ball, steepling ball or measuring ball transmission mechanism does not rotate flexibly or has abnormal sound, check whether the gear meshing is normal.

 Always check whether the fire ball, wave truncated ball, flattening ball and limit switch and reset switch of the ball drive mechanism are normal.When checking, the transmission mechanism should be turned to the limit position to see whether the limit switch and reset switch are normal.

 If you doubt the console of charging voltage meter and the digital voltage meter reading is normal, you should check for damage resistance of dc voltage divider, check whether the series resistance of the dc microammeter variablevalues, the final inspection of 150 kv dc voltage divider system, adjust the dc microammeter series parallel resistance, make the charging voltage meter and the digital voltmeter reading satisfies the requirement of accuracy.

  If the "INCREASE" button or "DECREASE" button of the ignition ball is pressed, and the ball clearance motor does not turn, check whether the fuse of the power supply of the ball clearance motor is fused.

  If the charging ammeter indicates a large value for a long time and the overcurrent protection action causes the power to trip, check whether the automatic grounding device is ungrounded, whether the high-voltage silicon rectifier is damaged and whether there is a short circuit fault inside the charging transformer.

  If press the trigger button, no high voltage trigger pulse output, should check whether console ignition ball gap distance share is too big, high-voltage silicon stack, current-limiting resistance and filtering capacitance is damaged, trigger transformer primary side current limiting resistor is break line, trigger transformer is damaged, the trigger button contact are in good condition.

 In wet weather, due to the charging equipment and insulation surface leakage current increase so that the charging voltage is not stable, even the use of automatic charging device is difficult to maintain a stable charging voltage, at this time is not suitable for high voltage under the use of impulse voltage generator and automatic control part.
