High voltage switches and circuit breakers works similar to the general interrupter device equipped with a simple but its structure is relatively simple picture shows a high-pressure compressed air load switch their work spindle is rotated clockwise opening in the opening action of the spring On the one hand crank slider mechanism by the upward movement of the piston to compress the gas transmission system on the other hand by two four-bar linkage consisting of the main knife to open and then push the knife so that the arc interrupter contacts open compressed air cylinders When passing through the vents blow out the arc by closing the main spindle and drive the knife and the knife while clockwise arc interrupter contacts before closing the spindle continues to rotate the main contact in the closing process is then closed at the same time opening spring carve storage Because load switch can not short-circuit breaking current so often and limiting the use of high-voltage fuse together limiting the use of current-limiting fuses function not only completed the task of breaking the circuit and can significantly reduce the thermal and electrical short-circuit currents caused by Dynamic effects. 4 combination appliances must require the selected value of the transfer current load switch or transfer of the current selection of the appropriate choice when the combination of electrical. Fuse selection should consider the rated current of the transformer load switch, overload factor of 1.5 Weinan load switch Which is better? Inrush current 12 times the 0.1s, and the surrounding environmental factors. Load interrupter switch according to their principles can be divided into gas, compressed air, SF6 and vacuum form. Arc between gas production by opening switch contacts generated glowing arc tube Tongchuan load switch Which is better? Produce gas extinguishing the arc, breaking with the increase in the number, the arc tube gradually burned, so to constantly replace the arc tube. Gas load switch only about breaking current 1000A or less. Gas pressure switch gas generated by the load interrupter switch Which Yulin moving contacts when opening movement of its good? , Moving contacts are hollow copper rod, containing a fixed piston movement generated by the sub-gate gas interrupter. Air pressure-load switch about breaking current between 1350 ~ 1850A, below this value will make the reliability of the product range is greatly reduced. Yulin load switch Which is better? Huayi Electric Power (certified), load switch provided by Xian Huayi power plant. Xian Huayi power plant (www.xahy.com) is a leader in Xi'an, high voltage circuit breakers, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Huayi power in leadership with the staff warmly welcome all inquiries negotiations to create electricity Huayi a better future.
