1, the phenomenon of (1), cable pipe multi-layer overlap, there are higher than that of the temple square steel bar gluten. (2), wire and tube side by side for more than 2 or 2 root clingy. (3), electrical, pipe buried depth of the wall is too shallow, and even buried outside the walls of the powder layer. Pipe die bending, folding, dent phenomenon. (4), wire and tube into the distribution box, pipe in mouth not to fill, in the show is too long; Nozzle is not level off, different length; Nozzle without skirts; Not locked. (5), embedded PVC wire pipe not with stopper head plug, but with the clamps bend mouth flat. 2, (1) analysis of the causes, generator construction personnel to the related specifications are not familiar with, careless attitude toward work and convenience, not according to the provisions. Construction administrator management does not reach the designated position. (2), architectural design layout and electrical professional cooperation is not enough, cause more narrow line pipe 3 phase induction motor through the same plane. 3, preventive measures (1), and to strengthen the quality control of construction process of site construction personnel, targeted training of workers; Management personnel must be familiar auto spare parts with related specifications, strict management.

(2), squirrel cage induction motor three phase induction motor small diesel engine wire and tube multi-layer overlap generally appeared in the high-rise building public channel. When tower house each layer has six sets of the above, the proposal had better use the public corridor of smallpox condole top civil ACTS the role of alternator generator way, so most of the electrical professional into the door line can be directly above the ceiling installation slot to houses. Also can adopt the way of increasing public aisle floor, to hidden many wire and tube. When electrical construction professionals cloth tube should reduce overlapping layers of line pipe at the same point. (3), wire layer cannot clingy, side by side, such as the construction of it is difficult to clearly separate, can be used to separate the small concrete. (4), wire inside the tube into a brick wall, the distance from the surface should not be a boy of 15 mm, to "horizontal flat vertical pipe laying. (5), wire and acmotortrading.blogspot.com tube bending radius (dark bury) should not be less water pump price than 10 times the pipe diameter, pipe bend to bend with pipe bender or kink holding level off is smooth, does not appear the phenomenon such as flat folding, dent. (6), wire and tube into the distribution box should level off, the length is 3 to 5 mm, tube with a sheath and lock box shell. Distribution box into the floor type wire tube, pipe distribution box should be higher than that of base surface is 50-80 - mm. (7), embedded PVC wire tube, it is prohibited to the nozzle with forceps clip flat, curved, fist application conforms to the pipe diameter PVC pipe stopper head to block, and adhesive binding firmly.

The above regulations is minimum, almost every family to feel the socket is synchronous generator not enough, want to use temporary line socket board added as a supplement, a socket board up three or four electric equipment is a common ac motor phenomenon, if these are small capacity, electrical equipment such as home computer for four or five socket, it is www.dongfeng- motor.com allowed. If the socket board at the same time, electric kettle, electric heater etc. Large capacity magnetic generator electric equipment is not allowed, because the wire would overload fever.

Rated current I = P30KW U0.38 KV / 1.732 * * 0.2 = 227.9081 A, but electric motor 12v 500w 30 kw motor power factor can't be so low ah, do you want to calculate no-load running current of motor. The question you ask is problematic. ac three phase motor 30 kw motor power factor should be above 0.75. If according to the capacity of current rating: I = P30KW U0.38 KV / 1.732 * * 0.75 = 60.7755 A. Teach you two formula, very useful: "capacity divided by the number of kv, dealer by coefficient of seventh. "A kw, two current" can estimate the rated current of three-phase motor. Low power factor, then the acmotor2.blogspot.com motor should be banned the example of the net. Line current of three-phase ac asynchronous motor I material 2 P, P - power, kw. I material 2 x 60 kw motor current 30 = 60 a.

Bootstrapping IPM

Because general inverter circuit, the upper arm three IGBT trigger reference is suspended, so the upper arm trigger need 3 set of isolated power supply. The lower arm three IGBT trigger pulse is the common reference to, only a set of power supply. So a total of up to 4 groups of isolated generator set spare parts power supply. And mitsubishi DIP - IPM using bootstrap circuit structure, can easily achieve single power drive. Specific working principle is as follows: when the DIP - IPM start, first to lower arm IGBT ac motor send enough sufficient charging pulse number or a single pulse, opened lower arm (N) of IGBT, the power supply of the arm caused by internal charging path through IPM make upper arm three bootstrap capacitance charging completely, to the www.facebook.com/guohong.trading upper arm three IGBT trigger pulse power supply. Then began a PWM control pulse. Bootstrap charge circuit path and working 3 phase induction motor sequence diagram.

The torque of the motor

The torque of the motor starting torque,maximum torque,and rated torque.Starting torque is produced when starting a 1.7 2.2 times larger than the rated torque of the torque,the starting torque can overcome the static friction of the rotor Wipe and motor driven by the www.dongfeng-motor.com load resistance.Torque is the largest in motor under the condition of overload a parameter self-adjustment,but when motor under the condition of overload,the speed three

phase generator of the rotor will be next Reduced,so under the condition of invariable

in the frequency of the power supply,conducting bar cutting rotor speed,stator will produce larger

induction in the rotor Electromotive force,and the rotor resistance of a conducting bar is certain,so

the rotor current produced by motor parts the conducting bar is bigger than normal runtime,according to the left hand rule Can know,magnetic field force and current into direct proportion,so the rotor on the output of the electromagnetic power will increase,and then lose on the rotor The mechanical power is bigger also,so that the motor has been running near the stable point.Rated torque is torque motor can be long-term and stable operation.
