微型直流电机启动前应该主要哪些事项?

来源:http://www.jnmcd.com 发布时间:2019-04-04 浏览:
1.直流电机的接线
1. Wiring of DC motor
发电厂普通采用并激式直流电机,其电枢端子为H1和H2并激式绕组的端子为B1和B2,它的接线方法是H1并接B1后接直流电源的正极,H2并接B2后接直流电源的负极。
Parallel excitation DC motor is commonly used in power plants. Its armature terminals are H1 and H2 parallel excitation winding terminals B1 and B2. Its connection method is H1 parallel to B1 and then to the positive pole of DC power supply, H2 parallel to B2 and then to the negative pole of DC power supply.
2.降落直流电机的起动电流
2. Starting Current of Landing DC Motor
普通除了小于4KW的直流电机能够直接起动外,一切的直流电机的起动都应把起动电流降到电机的额定电流的2倍以下。要降落起动电流,普通要在电机起动时,在电枢回路内,串入起动电阻来约束起动电流或在电机起动时,降落电机的起动电压来约束起动电流。由于在电枢回路中串入起动电阻,运用设备简单,经济牢靠,所以被普遍选用。
In general, except for direct starting of DC motors less than 4KW, the starting current of all DC Motors should be reduced to less than 2 times of the rated current of the motor. In order to reduce the starting current, the starting resistance should be connected in series to restrict the starting current or the starting voltage of the landing motor to restrict the starting current when the motor starts. Because starting resistance is connected in series in armature circuit, the equipment is simple and economical, so it is widely used.

3.直流接触器的线圈问题
3. Coil Problem of DC Contactor
关于工作用直流接触器,其接触器线圈应是可长时间工作的。而关于CZ0系列接触器来说,都是短时间工作的,因而作为长时间工作接触器时,其线圈绝不能焚毁,所以,在起动完毕后,应给工作接触器串入一个约150W,1000Ω的电阻,避免线圈焚毁事端。
As for the DC contactor used for work, its contactor coil should be able to work for a long time. As for CZ0 series contactors, they all work for a short time, so as long time contactors, their coils must not be burned. Therefore, after starting, a resistance of about 150 W, 1000 Omega should be added to the working contactors to avoid the end of coil burning.
4.直流电流的丈量
4. Measurement of DC Current
关于直流电流的丈量,普通选用分流器式,在主回路串入100A,75mv的分流器,分流器的正负极接75mv的0∽100A电流表。
For the measurement of DC current, shunt type is usually used. A 100A, 75mV shunt is connected in series in the main circuit. The positive and negative poles of the shunt are connected with a 0_100A ammeter of 75mv.
