Power supply bureau in order to improve their cost effectiveness requires the fan motor user to improve the power factor, the client what is good for us to improve the power factor? 1) by improving the power factor, reduce the total current in the circuit and power supply system of electrical generator set components, such as transformers, electrical equipment, wires, so not only reduce the investment costs, and reduce www.dongfeng-motor.com the loss of the power itself. (2) with the good work due to ensure value, thereby reducing the voltage loss in power supply system, can single phase 3 hp motor make the load voltage is more stable, improve the quality of electrical energy. (3) can increase the margin of the system, and dig out the motor electric potential ac synchronous generator supply equipment. If the system power factor is low, then on the basis of the existing equipment capacity, after installing capacitor, can improve the power factor, increase the capacity of load. , for instance, the power factor of 1000 kva transformer increased from 0.8 Motor parts to 0.8: this article from: get league BBS, compensation before: 1000 * 0.8 = 800 kw compensation: 1000 * 0.98 = 980 kw. Also a 1000 kva transformer, power factor change after, it can bear 180 kw load. single phase 2hp electric motor (4) reducing the user's electricity expenses; Through to reduce the loss of the above components and ANP gost motor increased electricity power factor.

Choose fuse type and capacity, according to the protection of the load characteristics, the electric motors size of the short circuit current working conditions and use of the occasion. Most of the small and diesel engine medium-sized motor with light load or full pressure relief starting, lamination starting current is usually 5 to 7 times of the rated current; The power capacity is larger, low-voltage distribution main transformer (including capacity) in 1000 ~ 400 electric water pump kva, system impedance is small, when water pump price short-circuit fault occurs, the short circuit current is larger; The workplace such as kiln, grinding, poor ventilation condition, the working environment temperature is higher.

Therefore, choose fuse breaking capacity and rated current of the melt, compared with the general industrial use should appropriately increase a bit. 3.1 the melt the experience formula of the rated current melt Electric motor rated current (A) = motor rated current (A) (3). 3.2 melt rated current simplified formula: "melt protection, kw by 6" the simplified formula, is refers to a 380 v cage motors, light load starting or decompression starting full pressure, low operating frequency, suitable for below 90 kw and cage motor. If the actual use of the motor starting frequently, or starting time is long, the empirical formula or water pump price the simplified formula of the above results can be appropriately increased a little, but it should not be too large. In short to achieve when the motor starting, melt by fusing; In the case of short circuit fault, the melt acmotor2.blogspot.com must be reliable fuse, squirrel cage induction motor cut off power supply, to achieve the purpose of the short circuit protection.

L, phenomenon (l), listed cable is installed is not regulated, and water pump price cable clutter in cable trench, bridge. (2), in the shaft, the cable hole wall sealing is not tight; Vertical fixed cable bracket is too small, too soft, downward sloping. (3), cable through the tube after not single phase motor sealing tight. Line (4), terminals (ear) is too big or too small, the wall is too thin, when pressure joint fracture. (5), the plug box installation of busbar is not straight, paragraphs bus is too long, not easy to transport and install. 2, (1) analysis of lamination the causes, the cable was not coordinate construction units, but their laying cable can pass. (2), and the construction unit in block heavy current generator shaft without good coordination, construction personnel don't master the plugging ac synchronous generator technology. (3), the material didn't pass the exam, purchasing personnel is not in accordance with the standard purchase cable fixed bracket and terminal in line (ears). (4), building professional for high voltage electrical professional do the area of the shaft is too small, result in heavy current shaft arrangement difficult.

3, preventive measures (1), and to coordinate between cable construction team, cable were lined up to the size and position, after the installation with moistureproof and anticorrosive card listed, indicating a variety of cable line number, type, specification and all points. On location is: the cable terminal head, turn in philosophy, mezzanine, the ends of the shaft, in cable trench technology hole manpower, etc. (2), with hemp yarn and asphalt mixture sealing shaft cable through the mouth of alternator generator the cave, there is outside into the door to the basement, the nozzle will be waterproof processing, and these needs and civil engineering professional work closely with. Clean up the site after diesel generator set the seal. (3), procurement to buy cable between round fixed bracket, terminal line (ear), and other materials, must be standardized in accordance with the purchase. When pressure joint, accurately choose the corresponding hydraulic clamp and the corresponding suite. (4), bus order, must ensure that each busbar shall not be greater than each floor high; Generally no greater than 3 m, to facilitate the handling inside the building and installation. (5), bus and accessories comes into play, we will acmotor2.blogspot.com strictly according to the GBJ149-90 "electric device installation bus device code for construction and acceptance and inspection of the contract. (6), install water pump price the plug box, horizontal flat vertical, reliable, solid contact with bus. Nine, indoor and outdoor cable structures and cable is not in conformity with the requirements l tube, phenomenon (1), in cable trench and concrete support installation is not flat, easily broken. (2), in cable trench, cable pipe drainage not free. (3), the buried depth of the cable passing enough, bell is broken, irregular. (4) the uneven, steel rust anti-corrosion paint, sealing especially pipe rust and corrosion is not doing enough.

Ceramic plug fuse should be installed vertically, qualified fuse, must be used in other water pump price copper wire, etc. Replace the fuse. Spiral can fuse power into the line on the center of the base terminal, they can pick up the load for the shell of the screw terminals. Replacing the melt, must first disconnect the electric equipment, in order to prevent the cause arc. Fuse line should be installed in each phase. In two phase line diesel generator three and three phase four wire circuits of the neutral line fuse is strictly prohibited. Fuse is used primarily as a short circuit protection fuse for quarantine purposes, the fuse must be installed in the line head end. Fuse is AC motor short circuit protection. Isolated power supply, safety maintenance. Knife switch function is to isolate the power and safety maintenance. Rubber cover porcelain bottom knife switch as general electric lighting, electric circuit control switch, also can be used for distribution of branch circuit switch. Three pole rubber cover auto spare parts knife switch when appropriate to reduce capacity can be used to frequent starting motor control switch operation, not three pole rubber cover knife switch power supply into line should press into the line on the static contact end seat, electric equipment below the outlet of a fuse. Knife switch when cutting condition, the handle should be down, turned on, the handle should be upward, cannot flip or diesel engine paperback, three pole rubber cover knife switch is short circuit protection. Isolated power supply, safety maintenance.
