Introduction: Leakage trace: Under the specified test conditions, the conductive path gradually formed on the surface of the solid insulating material under the combined action of the electric field and the electrolyte is called the leakage trace. Tracking: The process of forming leakage traces is tracking. The main test principle of the wire and cable tracking resistance tester is to output a certain high voltage through a high voltage source. Under the combined action of the high voltage and the electrolyte, the sample can judge whether the current of the ground terminal of the sample exceeds 1A in several cycles, so as to judge the solid insulation. The insulating properties of the material. The wire and cable tracking resistance tester produced by our company is currently the most advanced wire and cable tracking resistance test equipment in China. Features: 1. Operation mode: 10-inch touch screen display and operation control. 2. Control method: The core control components adopt Siemens PLC, which has strong anti-interference, high measurement accuracy, stable performance, safety and reliability. 3. Data acquisition: photoelectric isolation data acquisition voltage and current, reliable data, anti-interference 4. Boost mode: manual boost 5. Experimental cycle: the spray cycle can be set according to the experimental needs 6. Flow control: There is a flow meter to control the flow of corrosive liquid in the experimental process. 7. Replacement of corrosive liquid: During the experiment, the corrosive liquid can be recycled. If the corrosive liquid needs to be replaced, there is a special release interface, which can be directly discharged. 8. Test gas: During the test process, if the product test gas or peculiar smell can be eliminated by the exhaust fan. 9. Experimental lighting: There are special experimental lighting, which can be controlled according to the experimental needs. 10. Test alarm: the buzzer alarms when the current exceeds 1A or when the test time is reached 11. Alarm time: The buzzer alarm time can be set freely. 12. Anti-drip guide groove: During the test, the liquid dripped into the guide groove without leakage 13. 45 degree guide groove: the spray head is parallel to the guide groove, so that the spray head is always kept at 45 degrees. Technical parameter: Input voltage: AC-220V Output voltage: AC-0-5KV Electrical capacity: 7KVA Voltage test accuracy: <2% High-voltage side output current: >1A High-voltage side output current: When >250MA, the maximum voltage drop <5% Current measurement accuracy: <1% Spray range: > 1M The distance between the nozzle and the ground: >600CM The distance between the nozzle and the sample: >500CM The axis of the nozzle and the axis of the sample are at an angle of 45 degrees Spray speed at the sample: 3M/S The spray volume is: 0.5mm/min Standard spray cycle: spray 10S, intermittent 20S
