GB/T6535 High Voltage Traceability Testeraccording to the standard

GB/T6553-2014/IEC60587-1984andASTM D2303Test Method for Evaluating the Resistance to Tracking and Corrosion of Electrical Insulation Materials Used under Harsh Environmental Conditions

Product Features:

The testing instrument consists of an experimental part and a control part, designed in an integrated manner for easy on-site installation and debugging. The shell and structural components of the test chamber are made ofMade of SUS304 stainless steel or brass; The electrode head is made of SUS304 stainless steel, which is resistant to high temperature and corrosion; Accurate droplet counting and stable and reliable control system.

Scope of Application：

Under the influence of humidity and impurities in electrical products, insulation leakage may occur between charged parts of different polarities or between charged parts and grounded metals, resulting in electric arcs that can cause breakdown and short circuits in electrical appliances or material erosion due to discharge, and even ignite and cause fires. Leakage tracing test is a destructive test conducted on insulation materials to simulate the above situation. It is used to measure and evaluate the relative resistance of insulation materials to leakage tracing under the action of electric field and impurity water at a specified voltage. It is suitable for solid electrical insulation materials and products of electrical and electronic products, household appliances, such as relay sockets, transfer switch covers, contactors, etc.

performance parameters:

electrode material		Using upper and lower electrodes, apply2.5kV～10kVThe communication voltage. When the short-circuit leakage current in the test circuit is equal to or greater than 60mA, the time should be maintained for 2 seconds, Relay action, cutting off current, indicating that the test sample is not qualified
Drip device		The time constant of the drip device can be adjusted to control the drip volume and drip time interval；
Test voltage and current		500~10kV (adjustable)(Digital display); 5-60mA (adjustable in different levels), short-circuit current can reach 100mA; (digital display);
Current controlled impedance		60, 50, 30, 15K Ω or set according to actual requirements, achieve secondary test current by switching separately 10. Requirements for 22, 33, and 40mA
Secondary current limiting resistor		15K Ω or set according to actual circuit requirements;
Experimental electrode		Two pairs, namely smooth and burr free stainless steel electrodes with a thickness of 0.15mm, 12.7 × 25.4, and an angle of 160 °; The tungsten rod electrode has a diameter of 2.4 × 45mm and a head that forms a 30 ° angle with the axis;
Electrode to sample The applied forces are respectively		50g±5g。
Number of droplets		1~9999 (digital display, pre-set);
Test wind speed		0.2m/s (new standard);
pressure drop		At 1.0A0.1A (incorrect); 100mA (correct)±8%
Trace judgment		Judgment criterion A: When the current passing through the sample in the high-voltage circuit exceeds 60mA and reaches the endpoint, At this point, the overcurrent device cuts off the power supply. Judgment criterion B: When the electric trace reaches the mark on the surface of the sample 25mm away from the lower electrode, it reaches the endpoint.
