The choice of the form of plate switch structure with a knife

According to the role of it in line and its installation position in the complete sets of power distribution equipment to determine the structure of it. Only used to single phase motor isolate the power supply, simply 3 phase induction motor choose products with no arcing cover; Such as used for breaking load, it should be chosen with arcing cover, and it is through the lever to manipulate the product; Such as the central can't handle knife switch to cut off the load current, the other can be cut off water pump price in the form of a certain load current, but it must be chosen with arcing cover of the knife switch. rotor and stator In addition, still should root tree is positive or side operation, is a direct manipulation www.facebook.com/dongfeng.motor or lever transmission, is the connection or the plate in front of the plate to choose structure. HD11, HS11 for magnetic stand, don't cut off the circuit with a load, only for current isolation. HD12, HS12 for positive side operating repairs in front lamination machine small diesel engine of the switchgear, including arc extinguishing device knife switch can generator cut off under the rated current of the load circuit. HD13, HS13 behind permanent magnet generator for positive squirrel cage induction motor operation maintenance of the switchgear ac induction motor cabinet, including arc extinguishing device knife switch can cut off under the rated current of the load circuit. HD14 used in power distribution box, including arc extinguishing device knife switch can be operated on load.
