Problems solved by technology

Therefore, the coil temperature increases, which will lead to accelerated corrosion of copper
If it is not controlled early, it will cause local overheating and damage to the generator bar, and in severe cases, insulation breakdown will cause grounding accidents

Embodiment Construction

[0063] The special resin for internal cooling water of generators is composed of the following mass percentages:

[0064] Hydrogen type resin: 32%

[0065] Hydroxy resin: 60%

[0066] Alkalized resin: 8%

[0067] According to the mass ratio, the hydrogen type resin: 32%, the alkalized resin: 8%, and the hydrogen type resin and the alkalized resin are mixed to ensure uniform mixing. Hydroxygen type resin: 60% are packaged separately.

[0068] The special resin for internal cooling water of generators is prepared through the following steps:

[0069] 1. Salt water treatment:

[0070] Fill the ion exchange resin into the ion regeneration column, the filling height is 1 / 3 to 1 / 2 of the overall height of the ion regeneration column, and the resin layer is washed at a high speed by the way of water inflow from the bottom, and the flow rate of the washing section is controlled at 10 ~60m / h, loosen the resin layer and remove the mechanical impurities and finely divided resin powd...

Abstract

The invention relates to special resin for cooling water in a generator and a preparation method of the special resin. According to the invention, anion resin, cation resin and alkalized resin are deeply regenerated through a special process, so the regeneration degree of the resin is ensured, the transformation rate of the resin is improved, and the exchange capacity of the resin is greatly improved. The resin is proportionally mixed and packed in an ion exchange column of a cooling water system of the generator, and the cooling water in the generator is purified and undergoes ion exchange alkalization treatment in virtue of the characteristics of the special resin, so the pH value of the cooling water in the generator is increased. The cooling water in the generator is controlled to havestable conductivity, a moderate pH value and the lowest copper ion content, so the insulativity of a generator set and a phase modifier set is improved to the maximum extent, and an operation periodis long. The method provided by the invention has the advantages of simple process, convenience in operation and low maintenance cost.

Description

Technical field: [0001] The invention relates to a special resin for internal cooling water of a generator and a preparation method thereof. Background technique: [0002] Because the water internal cooling generator has the characteristics of large capacity, small size and light weight, it is widely used in large generator sets. There are too many accidents caused by the poor quality of the inner cooling water of the water inner cooling generator set. In order to prevent such accidents, a lot of research has been done on the inner cooling water quality and copper corrosion mechanism and anti-corrosion methods at home and abroad, and the conclusions are drawn: a. The lower the conductivity of the inner cooling water, the better the electrical insulation performance, and there will be no insulation faults such as electrical flashover; b. The root cause of copper corrosion is the presence of dissolved oxygen and dissolved carbon dioxide in the inner cooling water. Valence cop...
