High-voltage high-pressure gas pressure switch structure there are six kinds of load switch ① solid high-pressure gas load switch breaking arc itself use energy to arc chamber gas material produced arc gas blowing out its structure is simple to apply in 35 one thousand volts and below products ② high-pressure compressed air load switch breaking during use compressed air to blow out the arc piston structure is relatively simple to apply to the following products ③ 35 kV and high-pressure compressed air load switch using compressed air to blow out the arc carve off large current structure is more complex and more suitable for 60 kV high-voltage products ④SF6 load switch: use SF6 gas extinguishing its breaking current breaking capacitive current performance is good but the structure is more complex and is suitable for 35 kV These products are high-voltage load switch ⑤ oil itself by arc energy to break down the oil around the arc to extinguish the arc gasification and cooling of its structure is simple, but the weight of large apply to 35 kV and below high voltage outdoor products ⑥ vacuum load switch using a vacuum Electric arc extinguishing medium long-life high relative price applies to 220 kV and below load switch products use? Load switch is a switch between electrical circuit breakers and disconnectors between load switch price, with a simple interrupter device, Hefei load switch, can cut off the rated load current and a certain overload current, but can not cut off the short-circuit current. In simple terms, high voltage switches, that can take the load off the current switching equipment. Within FN12-12R.D / 100-31.5 type indoor AC high voltage load switch - fuse combinations (hereinafter referred to as FN12-12R.D combination of electrical appliances) is FN12-12D load switch off and S port LAJ-12 (XRNT mouth - 12) high-voltage current-limiting fuse together the indoor high voltage switchgear. It can be a reliable short-circuit current breaking up any current: breaking work load switch current, high voltage vacuum load switch, fuse breaking short-circuit current, joint breaking any overcurrent working between current and full short-circuit current, while fuse It allows through its impact load switch sub-gate. High voltage vacuum load switch | Xi'an high | Hefei load switch provided by the Xi'an Huayi power plant. "High-voltage vacuum circuit breakers, low voltage switch cabinet, box-type substation, power transformers, voltage and" preferred Xian Huayi Electric Power Equipment Factory (www.xahy.com), the company is located: Xi'an High-tech Zone Lu Xinan section II, Over the years, Huayi Electric Power to provide customers with the best quality of service, Contact: Mr. Welcome to the new and old customers call, letter, visit the guide, business negotiations.
