Intelligent monitoring method applied to modular ring main unit

Abstract

The invention discloses an intelligent monitoring method applied to a modular ring main unit. A monitoring module monitors environmental parameters inside a single ring main unit and transmits the environmental parameters to a control module. A threshold value is preset in the control module; the monitoring data transmitted by the monitoring module are compared with the threshold value; when the monitoring data are determined to exceed the threshold value range, a prompting module is ordered to perform a command. According to the invention, ventilation and heat dissipation can be carried out selectively; when heat dissipation is required, a top cover is lifted up by a top support unit to form a stable structure; when heat dissipation is not required, the top cover is laid down by the top support unit to form a sealed environment, thereby preventing entrance of external dust and realizing protection.

Description

technical field [0001] The invention relates to the technical field of power distribution automation, in particular to an intelligent monitoring method applied to a modular ring network cabinet. Background technique [0002] 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 A system in the optimal operating state of safety, reliability, quality, economy, and efficiency. In the distribution network automation system, all kinds of remote detection and control units installed in the medium and low voltage distribution network are distribution automation terminals, including DTU, TTU, FTU and other remote terminals. Among them, the distribution automation terminal DTU ...

Problems solved by technology

The ring network cabinet with a common box structure has a long production cycle, large size, and heavy weight. Due to its large size, the operation of each process is inconvenient, and the ring network cabinet with a common box structure has a single size and no modular design, resulting in the use of The flexibility is poor, it cannot be fully assembled according to actual needs, and it is difficult to replace the whole or part of it

[0004] Ring network cabinets generally have multiple vents (radiation vents) arranged in arrays on the cabinet body. The vents are only a single through hole and have no special structure.

Therefore, on the one hand, dust from the outside is easy to enter and accumulate for a long time, affecting the cleanliness of the interior and even the normal operation of the circuit; , the bottom position of the side or front of the cabinet where the conventional vents are set, which will affect the heat dissipation efficiency in the cabinet

[0005] Because the environmental parameters in the cabinet cannot be monitored in the conventional ring network cabinet, such as temperature and humidity, the user cannot know the environmental conditions in the ring network cabinet, so it is impossible to predict the timing of taking corresponding maintenance measures, which makes the long-term use of the ring network cabinet There are safety hazards and risks
