Abstract

The utility model provides a self-compensating type line loss reducing AC motor, wherein, a stator winding of the AC motor is connected in parallel with a compensation condenser and integrates into a whole with the AC motor. The utility model has the advantages of simple structure, reasonable structure, and convenient operation, and meanwhile, the AC motor belongs to dispersion compensation aiming at a fixing load arranged on the tail end of an electric network in a supply network, and thereby, the problem of line loss between the AC motor and a transformer station is solved, and the compensation effect is most thorough. The utility model enhances power factor, reduces line loss, and saves a lot of energy.

Description

Self-compensation type line loss reducing alternating current motor
The utility model relates to a kind of alternating current motor, especially a kind of self-compensation type line loss reducing alternating current motor that can improve power factor.
Because alternating current motor is an inductive load, power factor is low, and electric power system is caused harmful effect, shows that mainly the capacity of power-supply device can not be fully used, the power loss of transmission line is bigger, therefore need the reactive power of motor be compensated.Yet the mode that improves power factor at present mainly is to carry out in electric substation, belongs to the centralized compensation to a certain amount of not firm demand, causes the power dissipation concerns of (alternating current motor) this section circuit from the electric substation to the power consumption equipment to can not get solving always.Although resembling the such power consumption equipment of large-scale alternating current motor, some carries out terminal dispersion compensation by the mode of establishing the building-out capacitor cabinet in its vicinity in addition, solve the power dissipation concerns of circuit between power consumption equipment and the electric substation, but but existed problems such as installation, use inconvenience.
The purpose of this utility model is to provide a kind of self-compensation type line loss reducing alternating current motor, so as install, that prerequisite easy to use is issued to reactive power compensation is thorough, improves power factor, reduces the line power loss, the purpose of energy savings.
The purpose of this utility model is achieved in that on the stator winding of alternating current motor and is parallel with compensation condenser, and forms one with alternating current motor.
The utility model is owing to directly be connected in parallel on compensation condenser on the stator winding of alternating current motor, and with alternating current motor composition one, have advantage simple and reasonable for structure, easy to use.This alternating current motor belongs to the dispersion compensation at the terminal a certain firm demand of electrical network in supply network simultaneously, make the line loss problem between alternating current motor and the electric substation obtain solution, its compensation effect is the most thorough, improved power factor greatly, reduce line loss, saved a large amount of energy.
Below in conjunction with accompanying drawing the utility model is described in further detail.
