High-voltage switch cabinet temperature monitoring system and method

Abstract

The invention discloses a high-voltage switch cabinet temperature monitoring system and method. The system comprises a current transformer CT arranged on a busbar in a switch cabinet, a first wirelesstemperature measurement sensor arranged on the busbar in the switch cabinet, an intelligent temperature measurement and dehumidification device arranged on the inner wall of the switch cabinet, an on-site monitoring host and a server. A second wireless temperature measuring sensor and a humidity sensor are arranged in the intelligent temperature measurement and dehumidification device; the humidity sensor detects the humidity in the switch cabinet and starts dehumidification when the humidity reaches a preset value; the current transformer CT uploads the detected current passing through the busbar, the first wireless temperature measurement sensor uploads the detected busbar temperature, and the second wireless temperature measurement sensor uploads the detected environment temperature inthe switch cabinet to the on-site monitoring host. The on-site monitoring host uploads the data to the server; and the server performs fault judgment. The temperature and the humidity in the switch cabinet can be monitored in real time, and the operation safety of electric power facilities is ensured.

AI Technical Summary

Problems solved by technology

[0002] (1) The existing technology cannot realize the real-time upload platform of the internal information of the high-voltage switchgear

[0003] The current high-voltage switchgear usually displays the operating data of the equipment itself, such as whether it is charged or not, and its own operating environment data is secondary data. Power cabinet manufacturers have not yet paid attention to this range.

Since the interior of the high-voltage cabinet will be insulated and inflated, it is difficult to directly measure the internal condition of the cabinet as an old cabinet renovation and power company operation and maintenance service (the wired communication method is used because the construction needs to process holes, which does not meet the requirements of the high-voltage switch cabinet. State Grid security requirements; State Grid’s current platform communication is mostly 485 communication, which cannot meet the data upload requirements), which brings difficulties to the actual operating environment temperature and humidity status monitoring and inspection

[0004] (2) The existing technology cannot realize the self-regulation of the high-voltage switchgear environment

[0005] The current high-voltage switchgear usually adopts the method of installing a temperature measuring sensor when considering installing a temperature measuring device, but this kind of temperature measuring sensor usually does not have the effect of self-dehumidification and self-regulation

However, the traditional method of adding a heating plate can neither fundamentally reduce the moisture in the cabinet, nor can it make a comprehensive pre-judgment and response based on the current situation of the environment.
