Won't water cooling the generator stator cause a short circuit?

Water cooling of the generator stator generally does not cause a short circuit because sufficient insulation and leakage prevention are considered in the design.

However, due to the harsh operating conditions, water leakage from the water-cooled stator winding is a common fault and is common in domestic steam turbine generators. If the material of the hollow copper wire is not good, it will easily break and leak during operation. Winding ends are common sites for water penetration and leakage, sometimes leading to grounding and short circuits. When there are cracks or large holes in the leak area, hydrogen may be on top of the cold water tank in the stator. The reasons for water leaking at the end are:

a) The quality of the wire itself is not good or there are holes in the joints between thes wires causing water leaks.

b) The quality of the water pipes is poor or the joints of the water pipes are poorly installed or have loopholes.

c) Mutual friction between insulated water pipes can wear away the walls of the water pipes and cause water leakage accidents. During the installation and maintenance period of the unit, carefully check the end windings, cables, housings and other parts to ensure the normal operation of the generator.

What is the friction between the magnets and the copper wires in the generator?

Do you know the principle of the generator? Electromagnetic induction, I hope you are familiar with it. . I won't go into details.

We also know that objects such as iron, cobalt and nickel are magnetic, which is determined by their internal structure. Magnetic lines can pass inside. . .

Forwhat to use iron core? In abstract terms, this means using iron as a medium for magnetic field lines, otherwise magnetic field lines will be emitted everywhere. If there is an iron core, the magnetic field lines can follow the shape of the iron core, which means providing a loop for the magnetic field and reducing the loss of the magnetic field. Otherwise, the intensity of magnetic induction will be much lower. the copper wire cuts the magnetic field lines.

Copper loss and iron loss from the generator

There is no friction. The friction between the copper wire and the magnet in the generator will generate electricity, but this is not the effect of friction, but the copper wire moving in the magnetic field of the magnet, cutting the magnetic field lines and generating an induced current. Generator refers to a mechanical device that converts other forms of energy into electrical energy.e. It is driven by a water turbine, steam turbine, diesel engine or other electrical machine. It converts energy generated by water flow, air flow, fuel combustion or atomic energy. nuclear fission into mechanical energy and transmits it to the generator. It is then converted into electrical energy by the generator.

1. A large amount of copper wire is required to wind the transformer. These copper wires have resistance when current flows, the resistance consumes a certain amount of power. often consumed as heat. We call this type of loss a “copper loss.”

2. Iron loss includes hysteresis loss, eddy current loss and residual loss of magnetic materials, and the unit is W/kg (Watt/kg).

① Hysteresis loss refers to the inherent loss of ferromagnetic materials as magnetic media under a ccertain excitation magnetic field (loss generated during the conversion of electrical energy into magnetic energy

② Eddy); current loss means that when the magnetic flux alternates, the iron core generates an induced electromotive force and then generates an induced current in the form of a vortex, called eddy current. The loss caused by the induced current on the iron. core resistance is eddy current loss;

③Residual loss refers to the loss other than hysteresis loss and eddy current loss. Since it represents a small proportion, it can be ignored.
