二、工作原理
Second, the principle of work
绕线式三相异步电动机,转子绕组通过滑环与电阻连接。外部串接电阻相当于转子绕组的内阻增加了,减小了转子绕组的感应电流。从某个角度讲,电动机又像是一个变压器,二次电流小,相当于变压器一次绕组的电动机励磁绕组电流就相应减小。根据电动机的特性,转子串接电阻会降低电动机的转速,提高转动力矩,有更好的启动性能。在绕线式电动机的转子回路中串入一特制的电阻器,随着电动机的起动,当电动机转速均匀提升至接近额定转速时,电动机转子回路被短接而投入正常运行,电阻器自动退出。在整个起动过程中,因电阻器为纯阻性,因此,无谐波污染电网。
Wound rotor three-phase asynchronous motor, rotor winding through the slip ring connected with resistance. External concatenated resistance is equivalent to the rotor winding resistance increases, reduced the rotor winding induced current. Speak from a certain Angle, motor and a transformer, the secondary current is small, the equivalent of a transformer winding motor excitation winding current is reduced accordingly. According to the characteristics of the motor, can reduce the speed of the motor rotor series resistance, improve the rotational torque, have a better starting performance. In series with wound rotor motor rotor loop of a tailor-made resistor, with the starting of motor, uniform when the motor speed up to close to the rated speed, the motor rotor loop is sub and put into normal operation, the resistor automatic exit. In the starting process, because of the resistor is pure resistance, therefore, there is no power grid harmonic pollution.
