1、星形接法:就是三个绕组末端相连,首端分别接三相电源的三根火线。
2、三角形接法:就是三个绕组首尾相连,从三个顶点出三条线分别接三相电源的三条火线。
对于低压大功率电机(>3千瓦)来说,为了降低启动电流,一般采用三角启动法来启动电机,以免对变压器或其他设备造成伤害。对于高压电机来说,大多采用星形接法,目的是避免高压对电机线路和绝缘的损坏。直流发电机的工作原理就是把电枢线圈中感应的交变电动势,靠换向器配合电刷的换向作用,使之从电刷端引出时变为直流电动势的原理。
【英文介绍/For English】:
1. Star connection method: that is, the ends of the three windings are connected, and the first ends are respectively connected to the three live wires of the three-phase power supply.
2. The delta connection method: that is, the three windings are connected end to end, and the three wires from the three vertices are connected to the three live wires of the three-phase power supply respectively.
For low-voltage high-power motors (>3kW), in order to reduce the starting current, the triangular starting method is generally used to start the motor, so as to avoid damage to the transformer or other equipment. For high-voltage motors, star connection is mostly used to avoid damage to motor lines and insulation caused by high-voltage. The working principle of the DC generator is to convert the alternating electromotive force induced in the armature coil into a DC electromotive force when it is drawn from the brush end by the commutator and the commutation effect of the brush.
