Scope of use
Used for electrical and electronic products, household appliances and their materials for electrical indentation and corrosion resistance test, simulation in the power frequency (45hz-65hz), with liquid pollutants and inclined plane test sample, through the measurement of electrical indentation and corrosion resistance of electrical insulation materials used in harsh environmental conditions to assess the level of electrical indentation and corrosion resistance.
1.7 inch full-color programmable controller touch screen +PLC control, automatic calibration of liquid flow rate
2. The use of high precision constant flow pump to ensure the absolute accuracy of the flow rate, the general electromagnetic valve control can be compared
3. Removable dripping device is adopted to facilitate the cleaning of excess contaminated liquid
4. The alarm program of super-strong voltage and current protection can automatically detect the state of the door of the equipment. It cannot be tested when the door is open to ensure the safety of the test personnel
1. Test station: 5 (another one 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 operate, the current will be cut off, and the buzzer alarm will indicate that the test product is unqualified
3. Voltage, start, drain, switch, stop, exhaust and lighting are all realized on the touch screen. The test data can be stored in the touch screen
4. Voltage, dripping time, current, dripping velocity, equipment door state, maximum current, real-time display of experimental results
5. Filter paper size: according to the standard size requirements, the filter paper thickness is 0.15 ~ 0.17mm.
6. Drip device: high precision constant current drip device with adjustable height.
7. The drip device is removable to facilitate the cleaning of excess contaminated liquid, and will not flow the contaminated liquid into the box to corrode the box
8. The flow rate of the polluted liquid is between 0.075 and 0.9ml/min, which can be automatically adjusted and adjusted according to the voltage, saving the trouble of adjusting the flow rate after the voltage is adjusted
9. It can automatically check the liquid flow rate to ensure the accuracy of the flow rate and the accuracy of the test (generally, solenoid valve control in the market cannot guarantee the accuracy of the flow rate and the uniformity of the liquid).
10. Number of drops, time of drops and test time can be preset.
11. Automatically judge and prompt the state of the door. The door cannot conduct high pressure test when it is open, which effectively protects the safety of operators
12. Abnormal test voltage alarm.
13. Voltage over range alarm
14. Current overload protection, current over range alarm.
15. It indicates the peak current value
16. The top is equipped with a silent and anti-reflux exhaust device, which can discharge the smoke generated by combustion after the end of the test
17. With lighting function
18. Automatic maintenance at the end of the test
19. Contamination solution: ammonium chloride, isooctyl phenoxy polyethoxyethanol, non-ionic wetting agent with distilled water or deionized water mixture.Liquid pollution in (23) 1 ℃ resistivity should be Ω · m (3.95 and 0.05).
20. Electrode: the thickness of upper and lower electrodes is 0.5mm and 304 stainless material. The dimensions are made according to the requirements of standard sizes.
21. Power requirements: AC220 (10%) V/50HZ, 3KW
22. Overall dimensions: 1350 * 700 * 1600mm
Standard GB6553-2014 test method for evaluating resistance to electrical indentation and corrosion of electrical insulating materials used in harsh environmental conditions (IEC60587:2007, IDT)
