It is used to test the resistance of electrical and electronic products, household appliances and their materials, and simulates the electric trace and corrosion resistance of electrical insulation materials used under harsh environmental conditions by measuring the resistance to trace and corrosion at power frequency (45Hz – 65Hz) with liquid contaminants and beveled specimens. 【Relevant Standards】

Design Standard GB6553-2014 Test Method for Evaluation of Electrical Trace Resistance and Corrosion Resistance of Electrical Insulation Materials Used in Harsh Environmental Conditions (IEC60587:2007, IDT)

【Scope of application】:   It is used to test the resistance of electrical and electronic products, household appliances and their materials, and simulates the electric trace and corrosion resistance of electrical insulation materials used under harsh environmental conditions by measuring the resistance to trace and corrosion at power frequency (45Hz – 65Hz) with liquid contaminants and beveled specimens. 【Meet Standards】 :                                      Design Standard GB6553-2014 Test Method for Evaluation of Electrical Trace Resistance and Corrosion Resistance of Electrical Insulation Materials Used in Harsh Environmental Conditions (IEC60587:2007, IDT) [Instrument features]:  1. 7-inch full-color programmable controller touch screen + PLC control, automatically calibrate liquid flow rate 2. The use of high-precision constant flow dosing pump ensures the accuracy of the flow rate, which is more accurate than ordinary solenoid valves 3. Adopt a detachable drip device to facilitate the cleaning of excess contaminated liquid 4. Super voltage and current protection alarm program, automatically detect the status of the equipment door, and cannot be tested when the door is open, so as to ensure the safety of the test personnel 【Technical Parameters】:    1. Test stations: 5 (1 station configuration is optional) 2. Applied voltage: 0~6000V±5% adjustable, when the high voltage loop current reaches or exceeds 60mA for 2S in the test, the relay operates, the current is cut off, and the buzzer alarm indicates that the test product is unqualified 3. Voltage, start, drain, switching, stop, exhaust, lighting, etc. are all realized on the touch screen, the test data can be stored in the touch screen, and the save interface will automatically jump out of the save interface after the test, fill in the save name to save the data, and all the saved data can be queried in the historical data 4. Voltage size, dripping time, current size, dripping flow rate, equipment gate status, maximum current, and experimental results are displayed in real time 5. Filter paper size: made according to the standard size requirements, the thickness of the filter paper is 0.15 ~ 0.17mm. 6. Dripping device: high precision constant flow dripping device, dripping device height adjustable, 7. The dripping device is detachable, which is easy to clean up the excess contaminant liquid and will not flow the contaminant liquid into the box to corrode the box 8. The flow rate of the pollutant liquid can be automatically adjusted according to the voltage in 0.075 ~ 0.9mL/min, eliminating the trouble of adjusting the flow rate after adjusting the voltage 9. The liquid flow rate can be automatically calibrated, which ensures the accuracy of the flow rate and the accuracy of the test (generally the solenoid valve control on the market cannot ensure the accuracy of the flow rate and the uniformity of the liquid) 10. The number of drops, dripping time, and test time can be preset. 11. Automatically judge and prompt the door status, the door cannot be tested in the open state, which effectively protects the safety of the operator 12. Abnormal test voltage alarm. 13. Voltage over-range alarm 14. Current overload protection, current over-range alarm. 15. Indicate the peak current value 16. The top is equipped with a silent and anti-backflow exhaust device, which can discharge the flue gas generated by combustion after the test 17. With lighting function 18. Automatic maintenance at the end of the test 19. Contamination solution: ammonium chloride, isooctyl phenoxy polyethoxyethanol, nonionic wetting agent with distilled or deionized water mixture. The resistivity of the contaminant solution at (23 °C) 1°C should be (3.95 °C) 0.05) Ω·m. 20. Electrode: The thickness of the upper and lower electrodes is 0.5mm, made of 304 stainless steel, and the size is made according to the standard size requirements, and the spacing between the upper and lower electrodes is 50±0.5mm. 21. Power requirements: AC220(±10%)V/50HZ, 3KW 22. Overall dimensions: 1350×700×1600mm
