LW-126/3150-40 type self-energy AC high-voltage hexafluoride sulfur hexafluoride circuit breaker is an outdoor type product, applicable to an altitude of no more than 2000 meters (designed for an altitude of 3000 meters), ambient temperature no lower than -30 degrees Celsius, dirty The grade is not higher than IV class 50 AC 50Hz, the highest voltage is 126kv in the grid, to cut off the rated current, fault current or conversion circuit, to achieve control and protection of the power system, but also can be used as a tie breaker. This product uses SF6 gas as the arc extinguishing and insulation medium, adopts the most advanced self-energy arc extinguishing technology in the world, and is equipped with a new type of spring operating mechanism. It has the advantages of long electric life, small operation power, low noise and high reliability. Its simple structure, small size, no maintenance cycle, in the current power equipment tends to no oil, large-capacity process, can completely replace the same type of imported products.
