With the rapid development of information technology and the continuous emergence of new technologies, the intelligent dehumidification auxiliary monitoring system of distribution cabinet must be a high-performance and scalable computer network architecture to support the needs of continuous updating and upgrading in the future, and build the dehumidification wireless communication system of switchgear into an important node for intelligent power information access in the future, At the same time, the scheme is based on practical application, and the design mainly follows the following principles:

1. Reliability

The system reliability of intelligent dehumidification device is the cornerstone of long-term stable operation of the system. Only a reliable intelligent dehumidification system of distribution cabinet can play an effective role. From system design concept to system architecture design to product selection, this scheme will continue to adhere to the principle of system reliability, adopt mature technology, and have high reliability, strong fault tolerance and good recovery ability.

2. Economy

According to the different economic bases of different regions, the system economy should be considered to the greatest extent on the basis of meeting the system stability. The original auxiliary monitoring system of the power distribution room has been put into use and has not reached the service life, so it is unrealistic to replace it on a large scale. The intelligent dehumidification scheme of distribution cabinet needs to fully consider the reuse of the original system, protect the original investment and reduce the system cost and installation cost to the greatest extent.

3. Expansibility

The power intelligent dehumidification device system shall fully consider the expansibility, adopt standardized design, strictly follow the international, domestic and industrial standards of relevant technologies, ensure the transparency and interconnection between systems, and fully consider the connection with other systems; During the design and equipment selection, scientifically predict the future expansion demand and carry out margin design. The equipment adopts modular structure to facilitate system expansion and upgrading.

4. Ease of use

The intelligent dehumidification system of distribution cabinet adopts all Chinese culture software to realize the management and maintenance of the whole monitoring system. The man-machine dialogue interface is clear, concise and friendly, and the operation is simple and flexible, which is convenient for monitoring and configuration; Stable and easy-to-use hardware and software are adopted without any special maintenance tools, which not only reduces the training cost of professional knowledge for managers, but also saves the daily frequent maintenance cost.

5. Security

Comprehensively consider equipment security and network security. The wireless communication for dehumidification of switchgear adopts perfect security measures at the front end to ensure the physical security and application security of the front-end equipment. The communication security between the front end and the master station must be guaranteed, and reliable means must be taken to prevent illegal access, intrusion or attack of the front-end equipment.

6. Standardization

The design of power intelligent dehumidification device strictly follows the international, national and power grid industry standards of relevant technologies. The products used in the design are standardized and open, and meet the international agreements, so as to facilitate future use and maintenance.
