Today's automatic control technology is based on the concept of feedback. Feedback theory includes three fan motor parts: the elements of measurement, comparison and execution. Measurement concerned variables, compared with expectations, with the error correcting adjusting control system response. The fan motor stator winding theory and three phase motor application of generator automatic control is the key to make the right measurement and comparison, how can better correct the system. PID (proportional integral differential) controller as the earliest practical controller has 70 years of history, and still is the most widely used industrial controller. PID controller is easy motor electric to understand, there is no need of accurate www.facebook.com/dongfeng.motor system model in ac induction motor lamination use, such as precondition, and become the most widely applied controller. PID controller from the proportional unit (P), integral (I) and differential unit (D). Its input e (t) and the relationship between the output u (t) as follows: u (t) = KP [e (t) + 1 / TI ∫ e (t) dt + TD * (t)/dt] type integral in the upper and lower 0 s and t, respectively. So its transfer function is: G (s) = U (s)/E (s) = KP (1 + 1 / + TD * * s (TI) s]. The KP ratio; TI is integral AC motor time constant; TD for differential time constant

25, leakage with as for leakage protection (this is when the loop 30 ma leak current automatic trip, mainly to protect the human body electric shock), even with lighting line in Water pump theory, the home installs all the socket to match, but we suggest that only these wet with kitchen and toilet. Because good leakage protection is very sensitive and a bit of a electrician tape no good package, had a little auto spare parts leaking trip. In fact that 3 phase induction motor disclosure has no effect on the human body, especially in high power air conditioning, in 2 years after www.dongfeng-motor.com some internal components ageing slightly a little trip, this also is very troublesome.

There are a lot of alternator generator electrician also messing around, the following loop not leakage protection, and on the total open with a leakage protection. That you may have trouble, over 2 years home and that's a bit of a problem, contact point, casually or whatever that's a bit of a problem, electrical appliances, ha synchronous generator ha, I'm sorry, but the family there were no electricity! Of course, we don't seem to encounter this problem, ha ha, you think I am ac motor talking nonsense, that is diesel generator set 99.5% of the people do not have the correct use of the leakage protector. Leakage protector has a small button above, need you diesel engine to every few months to press, not to you for several years, probably won't play a role, that is, of course, don't jump.

Low voltage circuit breaker is www.facebook.com/guohong.trading generally divided into plastic shell type (also known three electric motors phase induction motor as the device type) and frame type (also called universal type) two kinds big. The motor under 380 v245kw and more choose molded case circuit breaker. Circuit breaker can be divided into the generator distribution line protection according to the use and protection, lighting protection circuit of the motor and electric leakage protection use and so on. 2.1 motor protection circuit breaker selection principles: (1) the set values for the long time delay current is equal to the rated current of the motor. (2) the instantaneous current setting: for the protection of cage motor circuit breaker, the adjusting current diesel engine instantaneous equal to 8 to 15 times the rated current of the motor, depending on the squirrel cage induction motor protected cage motor model, capacity and starting conditions.

For wound rotor motor protection circuit breaker, the adjusting current instantaneous is equal to (3 ~ 6) times the rated current of the motor, diesel generator set depending on the protected wound rotor motor model, capacity and starting diesel generator set conditions. (3) 6 times of long time delay current setting value can return time is greater than or equal to the starting time of the motor. According to the weight of the starting load, can choose to return time 1 s, 3 s, 5 s, one of an 8 s, 15 s. 2.2 circuit water pump price breaker tripping device setting current simplified formula: "instant-on, motor kw 20 times" "thermal trip, according to the rating of the above formula is to protect a 380 v control of three-phase cage type motor circuit breakers, instantaneous motion setting its electromagnetic tripping current, according to the number of" kw "20 times". For thermal trip, according to the rated current of the motor selection.
