NLD-AII insulator anti leakage trace measuring instrument Introduction: Composition of insulator leakage resistance trace measuring device: High voltage generator: mainly composed of voltage regulator and transformer, mainly used for boosting and lowering voltage. Atomization test chamber: mainly composed of atomization chamber and ultrasonic atomizer. In the atomization chamber, the ultrasonic atomizer generates atomized particles with a specified flow rate, which adhere to the surface of the insulator, form dew drops, and corrode the insulator. Control system: controls the start, pause, and end of the entire experimental system. Technical parameters: Input voltage: AC-220V Output voltage: AC 0-50KV, DC -50-0KV adjustable Electrical capacity: 50KVA Voltage test accuracy:<2% High voltage side output current: ≥ 1A When the output current on the high voltage side is greater than 250MA, the maximum voltage drop is less than 5% Current measurement accuracy:<1% Threshold switch: After opening the door, the voltage is cut off and automatically returns to zero Overcurrent protection: adjustable The distance between the test sample and the top of the fog chamber is greater than 400mm, Distance between the test sample and the wall:>400mm Quantity of test samples: 1 horizontal and 1 vertical Test time: 1000 hours Spray mode: ultrasonic atomizer Spray speed at the sample: 3M/S Spray volume: (0.4 ± 0.1) L/m3. H Fog chamber volume: 4m3 (length, width, and height=2000mm * 1200mm * 1700mm) Spray liquid: salt water prepared by NaC1 and deionized water Atomized particles: 5 μ m-10 μ m Control System: Embedded Industrial Computer Host size: length, width, and height=3400 * 1300 * 1800 (mm) Equipment weight: 300kG
