IEC60587 High Voltage Tracking Tester.
1. Overview. IEC60587 High Voltage Tracking Tester is a test equipment used to test the ability of solid insulating materials to withstand surface tracking traces. It simulates the leakage phenomenon on the surface of the insulating material caused by environmental factors during the normal operation of electrical equipment, and measures the quality of its leakage resistance by evaluating the degree of tracking on the surface of the insulating material.
Second, the test principle.
IEC60587 tracking tester adopts the method of constant voltage and timing electroerosion, and applies a certain DC voltage to the sample under the specified test conditions for a certain period of time. During the test, the leakage resistance of the specimen is evaluated by observing the formation and development of the trace on the surface of the specimen, and measuring the length, width and depth of the trace.
3. Equipment composition and characteristics.
1.Power supply: Provide stable DC power supply to ensure the accuracy and stability of the test voltage.
2.Test electrode: Typically needle electrode or plate electrode is used to apply voltage and conduct.
3.Specimen grip: ensure good contact between the specimen and the electrode, and facilitate the installation and replacement of the specimen.
4.Observation device: Equipped with a high-magnification glass or microscope to facilitate the observation of the development of electric traces on the surface of the sample.
5.Measuring device: It is used to measure the length, width and depth of the trace to ensure the accuracy of the test results.
6.Control device: realize the automatic control of the test process, including the setting of voltage and time, and the start and stop of the test.
Fourth, the test steps.
1.Preparation of the specimen: selection of suitable insulating materials, processing into the specified size and shape, cleaning the surface and pre-treatment.
2.Mounting the specimen: Place the specimen in the sample holder, ensuring good contact with the electrode.
3.Set test parameters: set test voltage, time and other parameters according to the standard requirements.
