Abstract

The invention discloses a ventilation device of a underground substation. The ventilation device comprises an air inlet pipeline, an air inlet in one end of the air inlet pipeline is connected with adraught fan unit, an air inlet in the other end of the air inlet pipeline is connected with a filtering unit, and a dehumidification unit is fixedly arranged in the air inlet pipeline; the air inlet pipeline is movably connected with an extrusion dewatering unit for rolling and extruding the dehumidification unit, the center of the filtering unit is rotatably connected with a cleaning driving unit, and the cleaning driving unit is in engaged transmission connection with an extrusion linkage unit; and one end of extrusion linkage unit is fixedly connected with an extrusion dehydration unit, andother end is movably connected with the air inlet pipeline. In a conventional state, an outer pipeline and an inner pipeline are in a state of being fixedly connected through a disassembly and assembly locking piece, external air enters a substation after being filtered and dedusted by the filtering unit and dehumidified by the dehumidification unit, and dust-free and dry power transformation equipment rooms can be ensured.

Description

technical field [0001] The invention relates to the technical field of substation ventilation equipment, in particular to a ventilation device for an underground substation. Background technique [0002] The substation is a key and important place where the high-voltage or ultra-high-voltage electric energy of the power grid is transformed and transmitted to the system users. It is a bridge between the power system and the users. In order to ensure the normal operation of substation substation and power transmission and distribution equipment, the industry requires that the substation equipment room must be moisture-proof at ordinary times, waterproof during flood seasons, keep warm in winter, and prevent small animals from entering. The ventilation design of capacitor rooms and grounded substations in existing substations mostly adopts natural air intake and mechanical exhaust. The dust-free and dry electrical equipment room may affect the running electronic components in ...
