Intelligent airing system for cable trench of transformer substation and working method of intelligent airing system

Abstract

The invention discloses an intelligent airing system for a cable trench of a transformer substation. The intelligent airing system comprises a field action mechanism, a temperature and humidity sensor and a field external electric control box, wherein the field action mechanism is arranged on a cable trench airing opening, a base is arranged on the cable trench airing opening, a cover plate covers an opening in the top of the base through a driving assembly, and the driving assembly can drive the cover plate to be opened; a solar base and a solar panel are arranged on the cover plate; the temperature and humidity sensor is arranged in the cable trench and is positioned near the field action mechanism; and the field external electric control box is arranged beside the field action mechanism in an open air mode and comprises a main control box and a rainwater sensor, a controller is arranged in the main control box, the controller is connected with an internal electric control box, and the controller collects signals of the temperature and humidity sensor and the rainwater sensor and controls the driving assembly to operate. According to the intelligent airing system for the cable trench of the transformer substation and the working method of the intelligent airing system, the cable trench airing opening can be automatically opened and closed according to the actual situation, and the labor intensity and the manual operation and maintenance cost are reduced.

Description

technical field [0001] The invention relates to the technical field of intelligent equipment and facilities for power transmission and transformation, in particular to an intelligent drying system for cable trenches in substations and a working method thereof. Background technique [0002] At present, the substation is equipped with multiple drying outlets on the cable trench. After the rainy weather, the operator needs to open the cover of the drying outlet to ventilate and dry, so as to prevent faults caused by water accumulation in the cable trench and excessive humidity. If the maintenance is not in place by the operating personnel, it will often lead to serious water accumulation inside the cable trench, which is a great safety hazard. However, if operators want to artificially open so many cable trench drying port covers, the work intensity is too high, and too much manpower is used, resulting in a further increase in labor costs. [0003] At the same time, with the p...
