Coil 1 is the main winding and the wire utilization is usually around 0.7, which is the group that occupies the most. Mainly provides 220V output power.
Coil 2 is the excitation winding. The one with brushes has 4 heads and the one without brushes has 2 heads. It mainly provides a motor to sense and provide excitation; Among the four heads with brushes on the left and right, two of them are sampling windings and the other two are excitation power windings.
Coil 3 is called DC power winding. It has two ends. The thread is thicker and uses the least amount. It mainly provides DC power to the panel or is used to charge the battery.
The generator stator is the fixed part of the engine. Its components mainly include iron core, machine base, coil and other components.
The generator stator is composed of iron core, frame, coil and other components.
1. Stator core
The stator core is the main magnetic circuit of the stator, and it is also the installation and fixing component of the stator winding. The stator core is composed of sector-shaped punching sheets, ventilation slots, tooth pressure plates, clamping bolts, support blocks, positioning ribs and other components.
The base is used to fix the iron core. For a suspension generator, the base serves to support the entire weight of the rotating part; the iron core is part of the magnetic circuit of the generator; The coil constitutes the heart of the generator circuit.
2. Framework
The main functions of the generator base are:
1. As a support structure for the stator core laminations;
< p>2. Support the torque of the stator and the transput at the feet;3. Form a channel for gas cooling
4. supporting structure;
The diameter of the stator base of large hydrogenerators is relatively large, and the vertical structure is mainly used, and most of them need to be manufactured in two parts.
3. Coils
Most stator windings of large hydroelectric generators use strip coils (also called metal bars) of double-layer corrugated windings. There are few internal connections and it is easy to disassemble and replace. For water-cooled generators, single-layer corrugated windings can also be used, which can simplify the cooling water line.
Wiring
The stator has two wiring methods, one is 4-wire type, the rotor is connected in series between the two stator windings, and the other is the 2-wire type. type, the two stators aret After the winding is connected, connect it to the rotor string, then connect it to the rotor string (connect the two diagonal wires of the 4-wire type together). The two wiring methods are different but can be used universally. There are two ways to bring out the wires: one is through a soft wire; the other comes out through the connector on the skeleton. The skeleton must be preserved when winding this type of wire.
