Name: YK-3057 Leakage Traceability Tester

[Product Introduction]：

This tester is suitable for electrical products that may be affected by moisture and impurities in the environment, and may cause insulation leakage between charged parts of different polarities or between charged parts and grounded metal parts. The resulting arc can cause breakdown and short circuit of the electrical appliance, or cause material corrosion due to discharge, and even ignite and lead to fire. This test instrument is a destructive test conducted on insulation materials to simulate the above situation, used to test and evaluate the relative resistance of insulators to leakage and trace under the action of electric field and impurity water at a specified voltage. Solid electrical insulation materials and products suitable for electrical and electronic products, household appliances, such as relay sockets, transfer switch covers, contactor bodies, etc. [Execution standards]：

[technical parameter]：

Ø Box volume: ≥ 0.5 cubic meters, with glass observation door

Electrical load: The test voltage can be adjusted between 100~600V, and when the short-circuit current is 1A ± 0.1A, the voltage drop should not exceed 10%. When the short-circuit leakage current in the test circuit is equal to or greater than 0.5A, the time should be maintained for 2 seconds, and the relay will act to cut off the current, indicating that the test sample is not qualified.

Ø Two pole force on the sample: Using a rectangular platinum electrode, the two pole forces on the sample are 1.0N ± 0.05N, respectively

Dropping device: Dropping height adjustable from 30mm to 40mm, droplet size 44 to 50 drops/cm3, droplet time interval 30 ± 1 second

Ø Timer: Imported timer, adjustable within the range of 0~99 minutes and 99 seconds, with an accuracy of ± 0.1 seconds
