Small long product life compact volume closing breaking ability easy operation and maintenance of vacuum switch with a spring operating mechanism uses a manual spring charging motor comes there way solenoid closing and closing manual points off two vacuum switch disconnectors mechanical interlock between the earthing switch interlock with each other in order to prevent misuse. When failure is not necessarily the same as a result of the three-phase current Zibo load switches, fuses and promised errors inevitably occur blown fuse time difference between the three-phase, after the removal of Prime Minister fault sunshine load switch, load switch, if not promptly breaking load current generation will result in the transfer of the current and two-phase operation Jining load switch, for receiving electrical equipment 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, when the load switch closing operation, while the storage sub-gate spring, when the four-bar linkage is too dead point, closing spring energy release, the switch for the closing operation, then divide axle brake spring energy 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. Linyi load switch _ Huayi Electric Power (certified) _ load switch provided by Xian Huayi power plant.
