The experimental operation method of the tracking tester
The tracking tester is on the surface of the solid insulating material at the specified size (2mm×5mm) between platinum electrodes, a certain voltage is applied and a polluted liquid (0.1% NH 4 CL) of a specified droplet volume is dropped at a fixed height (35mm) at regular intervals (30s) to evaluate the surface of the solid insulating material in the electric field and polluted medium. The tolerance under the combined action was determined by comparing the tracking index (CT1) and the tracking resistance index (PT1). Applicable to the research, production and quality inspection departments of lighting equipment, low-voltage electrical appliances, household appliances, machine tool electrical appliances, motors, power tools, electronic instruments, electrical instruments, information technology equipment, as well as insulating materials, engineering plastics, electrical connectors, The main performance characteristics of the equipment: 1. The imported solenoid valve is used to control the droplets, and the size of the droplets can be accurately controlled without adjustment! 2. The machine has a drainage function, which is convenient for emptying the air in the pipeline before the experiment! 3. Use a precision leakage current meter to quickly determine the leakage current of the product (to ensure the accuracy of the CTI index)! 4. The height of the sample stage can be precisely adjusted, and the front, back, left, and right positions of the two electrodes can be precisely adjusted, which is convenient for the test (completely improved with reference to the TESTING fixture, which is easy to use). The exhaust fan ensures that the box is sealed. And the exhaust effect is strong! 7. The box is made of 1.2mm mirror stainless steel box, which is beautiful and elegant! 8. The product accessories include precision electronic scales to verify the force of the electrode head on the sample! 9. The products use well-known brands such as Omron relays, YOTO timers, Meilan Geran leakage protectors to ensure long-term trouble-free operation of the equipment! This paper focuses on the experimental operation method of the tracking tester: 1. Compared with the tracking index (CTI): the highest voltage value that five test samples can withstand the test process of 50 drops without tracking failure and continuous flame . It also includes a description of the properties exhibited by the material when subjected to the 100-drop test. 2. Tracking Resistance Index (PTI): The test voltage value that five test samples can withstand the test process of 50 drops without producing tracking failure and continuous flame. 3. In layman's terms, CTI is the highest voltage that the material can withstand the 50-drop test process without causing tracking failure; PTI is to specify a test voltage, and then test whether the material can withstand the 50-drop test at this voltage. process. 4. The tracking index is used as an acceptance criterion and can also be used as a means of quality control of materials and components. Compared with the tracking index, it is mainly used to express the basic characteristics and characteristics of materials. 5. Evaluate the ability of solid electrical insulating materials to withstand wet surface discharge by applying the level of test voltage and the depth of electrical erosion. The comparative tracking index CTI and the tracking resistance PTI were determined. More about tracking tester: http://www.standard-groups.com/FlammabilityTesting/994.html
