Problems solved by technology
[0002] With the continuous increase of the service life, underground facilities such as cable trenches, cable tunnels, and oil storage tanks often generate water accumulation due to various reasons such as foundation cracks, poor power cable plugging, and installation terrain, which can increase the environmental humidity. Cause cable joints, switch knife condensate insulation drop or breakdown, cable service life reduced by 10%-15%, secondary equipment terminals corrosion DC insulation drop and other problems
Directly endanger the safe and stable operation of equipment and power grid and the personal safety of operators

The invention relates to an underground structure environment management and control system. The management and control system comprises a comprehensive controller, a sensor, a sewage pump and a ventilation and air change device; the comprehensive controller is fixed to a road facility, and the sewage pump is arranged on the underground horizontal plane of the road facility and is connected with the comprehensive controller; one end of a water draining pipe is communicated with the sewage pump, and the other end of the water draining pipe stretches out of the earth surface of the road facility; the sensor is arranged below the earth surface of the road facility, and is connected with the comprehensive controller; and one end of the ventilation and air change device is arranged below the earth surface of the road facility, and the other end of the ventilation and air change device stretches out of the earth surface. After the system is installed and runs, it can be ensured that the installing site environment meets safe and stable running of electrical equipment and life safety of workers.
Description
technical field [0001] The invention relates to an environmental management and control system for underground structures such as cable trenches, especially for equipment installation sites with high requirements for environments such as humidity and oxygen content, and is mainly used for environmental management of semi-enclosed underground hidden structures. Background technique [0002] With the continuous increase of the service life, underground facilities such as cable trenches, cable tunnels, and oil storage tanks often generate water accumulation due to various reasons such as foundation cracks, poor power cable plugging, and installation terrain, which can increase the environmental humidity. Cause cable joints, switch knife condensate insulation drop or breakdown, cable service life is reduced by 10%-15%, secondary equipment terminals are corroded and DC insulation is reduced, etc. It directly endangers the safe and stable operation of equipment and power grid and ...
