Gldq-6553 touch screen high voltage all - round upgrade!

7 "color programmable controller touch screen +PLC control!

It is applicable to gb6553-2014, which is used to test the resistance of electrical insulation materials to electric trace and corrosion. It supports two product configurations: 1 station and 5 stations.

Ii. Functions and features of gldq-6553 touch-screen high-voltage products

1. 7-inch full-color programmable controller touch screen +PLC control, automatic calibration of liquid flow rate

2. The use of high precision constant current refueling pump to ensure the absolute accuracy of velocity, not the general solenoid valve control can be compared

3. Removable drip device is adopted to facilitate the cleaning of excess contaminated liquid

4. Super voltage and current protection alarm program can automatically detect the state of the equipment door. It cannot be tested when the door is open to ensure the safety of test personnel

Iii. Main high voltage technical parameters of gldq-6553 touch screen

1. Test stations: 5 (another station is optional)

2. Applied voltage: 0 ~ 6000V±5% adjustable. When the high voltage loop current in the test reaches or exceeds 60mA and lasts for 2S, the relay will start to cut off the current, and the buzzer will alarm and indicate that the tested products are unqualified

3. Voltage, start, drain, switch, stop, exhaust and lighting are all realized on the touch screen. Test data can be stored in the touch screen

4. Real-time display of voltage, dripping time, current, dripping velocity, equipment door status, maximum current and experimental results

5. Size of filter paper: made according to standard size requirements, thickness of filter paper is 0.15 ~ 0.17mm.

6. Drip device: high precision constant current drip device, adjustable height,

7. The drip device can be removed to facilitate the cleaning of excess contaminated liquid and prevent the contaminated liquid from flowing into the tank and corroding the tank

8. The velocity of polluted liquid is 0.075 ~ 0.9ml/min, which can be automatically adjusted according to the voltage, eliminating the trouble of adjusting the velocity after adjusting the voltage

9. It can automatically verify the liquid flow rate to ensure the accuracy of the flow rate and the accuracy of the test (generally, the electromagnetic valve control on the market cannot guarantee the accuracy of the flow rate and the uniformity of the liquid)

10. Drip times, drip time and test time can be preset.

11. Automatically judge and prompt the state of the door. When the door is open, high-pressure test cannot be carried out, effectively protecting the safety of operators

12. Abnormal test voltage alarm.

13. Overvoltage alarm

14. Current overload protection, current over range alarm.

Tip peak current value

16. The top is equipped with a mute and backflow preventer to discharge the smoke generated by combustion after the test
