Scope:
Research, production and quality control departments for lighting, low voltage electrical appliances, household appliances, electrical machines, motors, power tools, electronic equipment, electrical instruments, information technology equipment, also apply to insulation, plastic, electrical connections, accessories industry.
Standard:
IEC60112: 2003 "solid insulating material resistant to tracking index and comparative tracking index measurement method the UL746A ASTMD3638-92, DIN53480, GB4706.1 and GB4207 standards such provisions simulation project.
Basic principles:
Electrical products by moisture and impurities in the environmental impact of the different polarity charging member, or between the live parts and between the grounded metal may cause a drain on the insulation, causing short-circuit breakdown or electric corrosion due to the discharge of the material by an arc generated on the electrical loss, ignition even cause a fire. Tracking test is a destructive test analogy above insulating material. Test is a certain voltage is applied on the surface of the solid insulating material, in a predetermined inch (2mm × 5mm) between the platinum electrode, and the timing (30s) a predetermined height (35mm) dropwise the predetermined droplet volume of the contaminated liquid (0.1% NH 4 CL), for the evaluation of the surface of solid insulating materials under the combined effects of the electric field and contaminated media tolerance, measured comparative tracking index (CT1) and the proof tracking index (PT1).
Main features:
Tester from the test section and control section uses the integrated design, easy on-site installation and commissioning. Convenient test chamber housings and structural parts are made of stainless steel or brass; control the droplets using state-of-the-art control technology, precise control of droplet size, and 20 drops of accuracy can be reached 0.02g, micro-pump front end with debugging emptying switch air electrode material within the experimental front empty pipeline using a combination of copper + platinum, precision adjustment of the level of the sample stage, the two electrodes of the fine adjustment around location, convenient test.
