Long vertical large-current enclosed busbar thermal equilibrium control system device

The utility model discloses a long vertical large-current enclosed busbar thermal equilibrium control system device which comprises the components of a temperature sensor which is arranged on the surface of the busbar, a ventilator which is arranged above the busbar, and a shutter valve which is arranged at the outlet of a busbar shaft. The output end of the temperature sensor is connected with the input end of a control box. The output end of the control box is connected with the control end of the ventilator and the control end of the shutter valve. The long vertical large-current enclosed busbar thermal equilibrium control system device has advantages of simple structure, reliable technique, high economical performance and high practicability. Through a coupling function between mechanical ventilation and natural ventilation, heat exchange capability in the busbar shaft is improved, thereby realizing benefit for energy saving and emission reduction. Operation of the ventilator and the shutter valve can be controlled according to different temperature conditions, thereby realizing thermal equilibrium of a long vertical large-current enclosed busbar.
