When failure is not necessarily the same as a result of the three-phase current, and the fuse promised errors inevitably occur blown fuse time difference between the three-phase, after the prime minister removal of fault, if the load switch can not be breaking the load current will result in generation transfer current and two-phase operation of the powered device damage. Fuse with the striker, with the tripping device has a load switch, you can solve the problem of missing running. When the fuse melting pieces melted, load switch tripping device under impact operation immediately disconnected. Plant more than a four-bar linkage Cangzhou high voltage load switch, load switch when closing operation, while the storage sub-gate spring, when the four-bar linkage is too dead load switch, closing spring release of energy, switch for closing operation, then the energy of the opening spring axle agencies still maintain that once the striker attack, axle splitting, opening spring energy release, the switch for the opening operation. Therefore, be sure to use fuses with striker and has a load switch mechanical tripping device. 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 transformer rated current, overload factor of 1.5 in Baoding high voltage switches, inrush current 12 times 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 hot arc tube, resulting in gas extinguishing the arc, with breaking number increased gradually burn Beijing arc tube high voltage switches, and therefore constantly changing arc tube . Gas load switch only about breaking current 1000A or less. Gas pressure switch gas produced by arcing when moving contacts its opening movement, 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. Cangzhou high voltage load switch | Switches | Huayi electricity provided by Xian Huayi power plant. Xian Huayi power plant (www.xahy.com) strong, credible, in Xi'an high-voltage circuit breakers and other industry has accumulated a large number of loyal customers.
