The role of generator rotor water inlet flange insulation

Insulating the water inlet flange of the generator rotor is the most basic and reliable way to ensure the safe operation of electrical equipment and circuits and to prevent personal electric shock accidents.

1. Generator insulation refers to the resistance between the generator stator winding and ground. Generally, if the insulation resistance of a generator is greater than or equal to 1 megohm per kV, the insulation resistance is considered qualified. For example, a 6 kV generator with an insulation resistance of 6 megohms or greater is qualified.

2. Insulation, a physics term, refers to a safety measure that uses non-conductive materials to insulate or encase charged objects to protect them from electrical shock. Proper insulation is the most basic and reliable way to ensure the safe operation of electrical equipment and lines.electric shocks and to prevent personal accidents by electrocution. Insulation can generally be divided into three categories: gas insulation, liquid insulation and solid insulation. In practical applications, solid insulation remains the most widely used and reliable insulation material.

How to check whether the winding inside the silicon rectifier generator is copper core or aluminum core without disassembling the generator

1) Excessive conductivity will cause a greater leakage current. the insulated water line will age and also cause flashover between stator phases.

2) The hardness of the cold water in the stator is too large, causing scale on the inner wall of the cooling tube in the hot state, reducing the cooling effect and even blocking it.

3) Copper pipes are subject to corrosion.

There are two general methods:The first is to perform a weight test on the silicon rectifier generator. Since the density of copper is much higher than that of aluminum, there should be a significant difference in weight. Of course, if you have a copper core generator, you can test them together and compare the data weight.

Second: Test the DC resistance value of the silicon rectifier generator. The conductivity of copper core wire is higher than that of aluminum core wire. be higher than that of aluminum core wire. The core should be small and a bridge can be used for testing. Compare the data.

Personal opinion: For reference only.
