Solid Insulating Materials High Voltage tracking indices Testing
Machine for IEC60112
Basic principle:
Under the influence of moisture and impurities in electrical
products, between different polarity live parts or between live
parts and grounded metal may cause leakage on the insulation. The
generated arc will cause electrical short circuit or discharge due
to electrical discharge. The material is electrically corroded and
even ignites causing a fire.
Leakage tracking test is a destructive test that simulates the
above situation on insulating materials. The test is on the surface
of the solid insulating material, applying a certain voltage
between the specified inch (2mm × 5mm) platinum electrodes, and
regularly (30s) to set the height (35mm) to drop the contaminated
liquid of the specified droplet volume (0.1% NH 4) CL), to evaluate
the resistance of the surface of the solid insulating material
under the combined action of the electric field and the
contaminated medium, and to compare the CT 1 and the PT 1.
Meet the standard: meet the GB/T4207 test standard requirements.
Technical parameters:
A rectangular platinum electrode was used, and the force of the two
poles on the sample was 1.0N±0.05N, respectively.
The applied voltage is adjustable between 100-600V (48-60Hz). When
the short-circuit current is 1.0±0.1A, the voltage drop should not
exceed 10%. When the short-circuit leakage current is equal to or
greater than 0.5A in the test circuit, the time is maintained. In 2
seconds, the relay operates to cut off the current and indicate
that the test sample is not qualified.
The time constant of the drip device can be adjusted, accurately
controlling the drip volume of 44 to 50 drops/cm3 and the drip time
interval of 30±5 seconds.
