Project brief introduction:

1000kV Shanghai West substation is an important part of the Anhui east power transmission project. It is listed in the national "12th Five-Year" development plan, and is the key implementation project to implement the strategy of "strengthening the power and strengthening the power" in the State Grid.

The "East Anhui power transmission project" is the world's first double circuit UHV AC transmission project on the same tower. The project starts in Huainan, Anhui, and reaches the Shanghai Shanghai West substation in southern Anhui and Northern Zhejiang. The long-term transmission capacity will reach 9 million kilowatts to 10 million kilowatts, and the annual electricity delivery will be about 50 billion kilowatts. This is of great significance for ensuring the safe and reliable power supply of Shanghai City, and at the same time, it is conducive to further improving the power of receiving power outside the Yangtze River delta power grid and resisting the serious failure of large capacity DC transmission projects. The East Anhui power transmission project is completely designed, manufactured and constructed by our country. It represents the highest level of international high-voltage AC transmission technology development, equipment manufacturing and engineering application.

The project is an important part of the planned UHV loop network in the Yangtze River Delta. It is conducive to solving the problem of over 500 thousand short circuit current in East China power grid, improving the flexibility and adaptability of power grid operation, significantly enhancing the power grid's ability to withstand serious faults, ensuring the safe operation of large capacity and multi infeed DC systems, further expanding the proportion of external electricity and meeting the demand for electricity in the Yangtze River Delta. It is of great significance to implement the national air pollution control action plan.

 

Product Description:

Our transformer cooling control cabinet installed in Shanghai Shanghai West substation has passed the acceptance inspection with advanced technology and perfect service, and has officially put into operation. For the smooth operation of the project, the company has organized a project tackling group. From the analysis of the technical indicators in the early stage of the project to the optimization of the later production process, one after another technical difficulty has been tackled, such as the reliable operation of the system under the high electromagnetic radiation environment, and the temperature and humidity control problems in the outdoor running cabinet of the Yangtze River in the three corners of the Yangtze River. After many times of demonstration and repeated tests, 大电竞app , who was strict and conscientious and conscientious, handed in a qualified answer and achieved excellent results again.

The features of the 1000kV transformer cooling control cabinet are:

The ABB cabinet has been used in 1. cabinets and tested strictly. The margin of components has been increased accordingly in the large current loop.

2. the structure and size of the cabinet were optimized and stainless steel was selected. Based on regional problems, the problems of corrosion resistance, typhoon prevention, high temperature resistance and anti condensation are taken into account.

3. the wiring process adopts the method of separating the primary circuit from the two loop, separating the AC from the DC, and separating the strong current from the weak current.

The components in the 4. cabinets are arranged longitudinally according to the control objects, and the gap between components is properly enlarged, and the distribution of large current and hot spots is considered as a whole.

5. in the high electromagnetic radiation environment, the shielding and grounding are strengthened.

6. control logic is strictly implemented according to DL/T 572-2010 "power transformer operation regulation".
