technical field

The utility model belongs to the field of electric power systems, and in particular relates to a constant temperature and humidity distribution network automation pole-mounted switchgear. the

Background technique

Distribution network automation is the use of computer technology, automatic control technology, electronic technology, communication technology and new high-performance power distribution equipment and other technical means to conduct offline and online intelligent monitoring and management of the distribution network, so that the distribution network is always in the Safe, reliable, high-quality, economical and efficient optimal operation status. Its ultimate purpose is to improve the reliability and quality of power supply, shorten the time for handling accidents, reduce the scope of power outages, improve the economy of power distribution system operation, reduce operation and maintenance costs, maximize the economic benefits of enterprises, and improve the efficiency of the entire power distribution system. Improve the level of management and work efficiency, and improve the level of service for users.

Distribution network automation system generally includes distribution main station, distribution substation, distribution remote terminal (FTU, DTU, TTU, etc.) and communication network. The power distribution main station is located in the city dispatching center, and the distribution substation is deployed in the substation. The main station is responsible for communication with each substation, and the distribution substation is responsible for communication with power terminal equipment such as DTU/TTU/FTU in the area under its jurisdiction.

At present, after continuous transformation and development of power grids in various places, the number of connections and segments in the middle of distribution lines is increasing, and the lines are becoming more and more complex. Relying on the switch on the column can realize that the switch will automatically trip when the line is overloaded or faulty. Power outage protection grid security. However, because the current pole-mounted switches are generally exposed outdoors, they will be affected by factors such as ambient temperature and humidity, thereby affecting their working reliability and lifespan.

Utility model content

The utility model aims at the deficiencies of the above-mentioned prior art, and provides a constant temperature and humidity distribution network automation pole switch cabinet which can make the pole switch work in a constant temperature and humidity environment.

The utility model is achieved through the following technical solutions:

A constant temperature and constant humidity distribution network automation pole-mounted switchgear, comprising a sealed and fastened cabinet body and a cabinet door, a pole-mounted switch is arranged inside the cabinet, an environmental monitoring module is disposed inside the cabinet door, and the environment monitoring The module includes a controller, a semiconductor air conditioner, a temperature and humidity sensor inside the cabinet, a temperature and humidity sensor outside the cabinet, and a communication interface unit. The semiconductor air conditioner, the temperature and humidity sensor inside the cabinet, the temperature and humidity sensor outside the cabinet, and the communication interface unit are all connected to the controller. The controller performs data interaction with the power distribution master station through the communication interface unit.

With such a setting, the switchgear on the pole can automatically adjust the temperature and humidity inside the cabinet to ensure the constant temperature and humidity inside the cabinet, and improve the reliability and service life of the switch on the pole; at the same time, the environmental monitoring module can also upload the environmental data to the distribution box. Power master station for monitoring.

Further, the communication interface unit includes an Ethernet interface unit, an RS232 interface unit and an RS485 interface unit.

With such a setting, various data lines can be used to connect the switchgear on the column with the power distribution master station according to different application occasions.
