Proportional gain P is determined, set a large integral time constant Ti initial value, then decreases Ti, until the system oscillation, in turn, after gradually increasing Ti, until the system oscillation. Ti records www.facebook.com/dongfeng.motor at this time, lamination set the PID integral time constant Ti for the current value of 150% ~ 180%. Integral time constant three-phase asynchronous motor gost Ti debugging. Integral time constant of Td generally generator rotor and stator don't have to ac generator single phase 2hp electric motor set to zero. If you want to set, the same as the P and Ti method, AC motor take no oscillation of 30%.

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

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.

19, large living room three phase induction motor air conditioning. This generally adopt the mode of single loop, many people have a misunderstanding, think to 6 square wire, this is wrong. We to calculate calculate four square wire and the maximum load is how much? 4 * 220 * 6 (be on the safe generator side, we coefficient is low) ac synchronous generator = 5280. General how many watts of the sitting room is big air conditioning, ha ha. More than 3000? Already very insurance? Of course, the sitting room of your home is very big, buy what big 4 p, 5 p you or 6 wires. 20, bedroom air conditioning. Bedroom air small diesel engine conditioning is usually 1 or 1.5 P, P, therefore, a circuit can be a single air conditioning, two air conditioning can also be a loop, when a single air conditioning circuit, 2.5 line is enough. Two air conditioning a loop, or be on the safe side, with four. Although calculate load, 3 bedrooms with four line belt air conditioning is enough, however, we do not recommend to do this, the main reason is that voltage instability in summer, one thousand at electric motors the same time use (although the possibility is very small, but does not rule out a third generation, and one out of the question, there is always a in use), may be frequent trip. Therefore, a principle, unless one hall, the bedroom air magnetic acmotor2.blogspot.com generator conditioning at ac motor most two series, and keep at least 2 loop (ha ha, this bad to go to sleep that).

According to the role of it in line and its installation position in the three phase induction motor complete sets of power distribution equipment to determine the structure of it. Only used to isolate the diesel engine power supply, simply choose products with Electric motor 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 in the form of a certain alternator generator load current, but it must be chosen with arcing cover of the knife switch. In addition, still should root tree is positive or side operation, is a direct manipulation or lever auto spare parts transmission, is the connection or the plate in front of the plate to choose structure.

HD14 used in power distribution box, including arc extinguishing device knife switch can be operated on load. 2. The selection of the rated current. Rated current of the knife switch, shut off by general should not be less than the sum of each load rated current in the circuit. If the load is the motor, we ac synchronous generator must consider whether the possible maximum short-circuit peak current in circuit in the level of the rated current of electric stability under the peak current (when short circuit accident, if the knife switch can pass with a maximum short-circuit current, is not produced because of its huge electric effect and produce the deformation, damage or touch the knife automatically pop up phenomenon, diesel engine is a short-circuit current peak is magnetic generator the knife switch electric stability of peak current). If you have more than, you should choose rated current a greater level of knife switch.
