Melt tube fuse installed in the fuse body. Then inserted in the holder or directly used on the circuit. Fuse is set at both ends of a metal cap or completely sealed with a touch of insulated pipe cutter. This fuse inside an insulating tube if filled with quartz sand, it has the effect of limiting breaking current time, can greatly improve the breaking capacity, it is also known as high breaking capacity fuses. If the inner tube is evacuated, the known vacuum fuse. If the tube is filled with SF6 gas Shijiazhuang fuses Which is better? , Then known as SF6 fuse fuse Shenyang Which is better? , Whose aim is to improve the arc extinguishing performance. Because of quartz sand, vacuum and SF6 gas has better insulation properties, so this is not only suitable for low voltage fuses are also suitable for high pressure. 2, the main shortcomings and weaknesses of the fuse must be replaced 1) after failure fuse fuse; 2) protection function of a single, only some characteristics of inverse time overcurrent Baotou fuses Which is better? , Overload, short circuit and ground fault protection are used here; 3) the occurrence of a phase is blown, three-phase motor will lead to adverse consequences of the two-phase operation, of course, an alarm signal is available with a fuse to be filled, a phase fuse can be broken open three-phase; 4) can not be achieved remote control, you need electric knife switch, switch combination is possible. Langfang fuse Which is better? Huayi Electric Power (certified), fuses 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.
