Automatic ventilation control device for electric power tunnel

Abstract

The invention discloses an automatic ventilation control device for an electric power tunnel. The automatic ventilation control device for the electric power tunnel comprises a CPU control module and a power module. The input end of the CPU control module is connected with a signal gathering module and a wireless remote control module. The output end of the CPU control module is connected with a controllable switch output module. The power module supplies electricity to the signal gathering module, the CPU control module and the controllable switch output module. The signal gathering module comprises a temperature detecting module, a humidity detecting module, a smoke detecting module, a water level detecting module, a combustible gas detecting module, a button start input module and a button stop input module. The CPU control module sends a corresponding action instruction according to data gathered by the signal gathering module, and the instruction sent by the CPU control module is executed through the controllable switch output module, so that all environment parameters in the electric power tunnel are automatically adjusted and controlled; an adjustment and control instruction can be sent to the CPU control module through the wireless remote control module, and human intervention is achieved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a detection and control device for adjusting indicators such as temperature and humidity in an electric power tunnel. Background technique [0002] With the rapid development of the national economy and the continuous improvement of the living standards of the people, the load of my country's power grid has been increasing year by year. In order to meet the needs of the development of the power system and ease the power supply pressure in the central city, 500kV substations have gone deep into the city center, and power cables will be used for the 500kV transmission lines in the urban area. 500kV cables have high requirements for heat dissipation around the cables due to their transmission capacity requirements. The original common laying methods such as pipe arrangement, direct burial, and cable trenches are no longer suitable for the needs of 500kV cables. Therefore, t...
