Three high and Electrical Equipment Co., Ltd. Wuhan Wei Olympic relay calibrator - WAWS20 portable gas (gas) Overview: Following Paul Star-WAWS20 portable gas relay calibrator based on the Ministry of Electric Power of Technology [1994] No. 209 The text released national power industry standard production QJ-25, 50,80 gas relay the inspection regulations "DL/T540-94 design. Following Paul Star-WAWS20 portable gas relay calibrator is a newly designed gas relay calibration and testing equipment. The calibrator analog transformer internal fault the gas relay action mechanism, a new generation of embedded control and high-precision sensor measurement technology, accurate check protection operation of the heavy gas flow rate value and light gas protection action gas volume value. One-button operation, testing speed, high-accuracy, attractive interface. Main features: 1. Accurate calculation of the calibrator using the pipeline design, the use of high-precision digital sensor equipment, making the measurement accuracy and measurement speed is greatly increased by the optimization algorithm with high-speed ARM chip platform; the oil return new design principle and After the flange becomes head of the special design, can save time, effort, to stable market a variety of common specifications (Φ25, Φ50, Φ80) Gas Relay checksum. A change similar equipment can only measure a single specification gas relay measurements need to be measured repeatedly reversed, high measurement accuracy, repeatability and measurement of the complex operation, and other shortcomings. This equipment the flange becomes head with a special design, the use of imported high-precision pressure control system with intelligent measurement system, the operator simply a key to simple, quick completion of the gas relay the test through random self print data with the miniature printer or storage to the U disk. Flow rate measurement accuracy of 0.01m / s, the volume measurement resolution of 5 ml of. Equipment performance and stability. Oil, electricity, gas, completely isolated, signal lines, power lines, pneumatic pipe completely separated, each module separation of layout and perfect shielding, fully ensure the adaptability and reliability of the equipment on-site test environment. The tester technical performance comparable to expensive the large stationary oil pump check Taiwan, and has a small size, easy to carry, simple to operate, to meet the needs of field trials, saving a lot of equipment and laboratory investment advantages. The main technical parameters: Operating voltage: control box: AC220V, 50Hz, 320W air compressor: AC220V, 50Hz, 120W (optional) Operating temperature: -10 ° C to +60 ° C velocity detection range: Φ25: 0 ~~ 2.0m / s , Φ50: 0 to 2.0m / s, Φ80: 0 ~~ 2.0 m / s minimum resolution of 0.01m / s; gas volume detection range: 0 to 500 ml, the minimum resolution 5ml; sealing performance test: 0.1 ~~ 0.5MPa 0 to 60 minutes, the minimum resolution 1Kpa; test medium: various types of transformer oil Dimensions: Gas relay school
