Problems solved by technology

[0002] With the rapid development of the national economy and the continuous improvement of the living standards of the people, the load of the power grid has been increasing year by year. The traditional pipe laying has been difficult to meet the needs of the power connection lines between the central substations, and the crowded underground space in most cities also makes the pipe laying difficult. The choice of path is becoming more and more difficult, and power cable tunnels must be used for laying

Abstract

The invention relates to a device and a method for intermittently ventilating and cooling a cable tunnel. The device comprises a temperature acquisition assembly, a fan controller and a fan which are sequentially connected with one another. The method includes that the temperature acquisition assembly measures the temperature of the inside of the cable tunnel and the temperature of an external atmospheric environment in real time and transmits the temperature of the inside of the cable tunnel and the temperature of the external atmospheric environment to the fan controller; and the fan controller intermittently starts or stops the fan according to current temperature conditions to cool the cable tunnel. Compared with the prior art, the device and the method have the advantages of good ventilating and cooling effects, capabilities of saving energy and advantageously prolonging the replacement cycle and the service life of the fan in the tunnel, and the like.

Description

technical field [0001] The invention relates to a cable tunnel auxiliary device and an implementation method, in particular to an intermittent cable tunnel ventilation cooling device and cooling method. 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 the power grid has been increasing year by year. The traditional pipe laying has been difficult to meet the needs of the power connection lines between the central substations, and the crowded underground space in most cities also makes the pipe laying difficult. The choice of path is becoming more and more difficult, and power cable tunnels must be used for laying. [0003] As more and more cable tunnels will be built, the section will become larger and larger, and the number of cables to be accommodated will also increase. The diameter of some tunnels can reach 5.5m (similar to the section diameter of rail transi...
