The invention discloses a box body of a switching station. The box body is characterized in that an opening is formed in the top of a housing; a top plate is arranged above the housing vertically along a horizontal direction; blades of a first ventilator are arranged at the opening and an air outlet end of the first ventilator faces the outside of the housing; and a rotating shaft of the first ventilator is connected to a rotating shaft of a drive motor coaxially. The drive motor is arranged in the top plate. A temperature sensor is arranged inside the housing to sense the temperature inside the housing and is configured to be connected to a comparator electrically. When the temperature is larger than a preset temperature, the comparator outputs a trigger signal to a trigger switch; under the circumstance that the trigger switch receives the trigger signal, the trigger switch is turned off; and the trigger switch, a power supply, and the drive motor form a closed loop. And when the temperature is smaller than or equal to the preset temperature, the comparator does not send out a trigger signal. Therefore, cooling of a switching station can be realized.
Description
technical field [0001] The invention relates to the field of electrical switch cabinets, in particular to switch station cabinets. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. load shedding. [0003] The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors, load switches, operating mechanisms, transformers and var...
