Abstract
The utility model discloses a built-in cabinet and belongs to the technical field of middle and high voltage distribution devices. The cabinet comprises a front cabinet, a rear cabinet, and a blower fan. The lower part of the front cabinet is provided with a cable chamber. The upper part of the rear cabinet is provided with a bus chamber. The top of the bus chamber is provided with a voltage-relieving channel. The interior of the voltage-relieving channel is provided with a voltage-relieving top plate. The top plate of the bus chamber is provided with a first vent hole which is communicated with the voltage-relieving channel. The blower fan is disposed at the top of the bus chamber, and the air inlet of the blower fan is aligned with the first vent hole. The installation position of the blower fan is changed from the top of the front cabinet to the top of the bus chamber of the rear cabinet, and the air outlet of the bus chamber serves as the main outlet of a vent path, thereby enabling the interior of the whole built-in cabinet to be in the state of negative pressure when the blower fan is started. Cold air is supplemented from each air inlet of the built-in cabinet, and passes through the bus chamber, thereby apparently cooling the whole built-in cabinet.

And in existing middle-placed switch cabinet, exhausting assembling is in front cabinet top, ventilation circuit setting is not good, and the radiating condition extreme difference of bus-bar room makes the temperature rise of whole cabinet be difficult to lower.
Summary of the invention
Based on this, the purpose of this utility model is to overcome the defect of prior art, and a kind of middle-placed switch cabinet is provided, and the cooling system of this middle-placed switch cabinet is obvious to the heat radiation of bus-bar room, and the cooling of whole cabinet is also very obvious, and its temperature reduction performance index is far superior to national standard.
For achieving the above object, the utility model is taked following technical scheme:
A middle-placed switch cabinet, comprises front cabinet, rear cabinet and exhausting blower fan, and described front cabinet bottom is provided with cable vault, described after cashier's office in a shop portion be provided with bus-bar room, this bus-bar room top is provided with pressure release passage, is provided with pressure release top board in this pressure release passage; The top board of described bus-bar room is provided with the first air vent hole being communicated with pressure release passage; Described exhausting assembling is in bus-bar room top, and its air intake vent is aimed at described the first air vent hole.
The utility model is found by research, in existing middle-placed switch cabinet, bus-bar room weak heat-dissipating is because exhausting assembling is in front cabinet top, ventilation circuit setting is good causing not, therefore, in middle-placed switch cabinet of the present utility model, exhausting blower fan is changed into the bus-bar room top that is mounted to rear cabinet, using the wind path outlet of bus-bar room as the main exit of ventilation circuit, when exhausting blower fan starts, in whole middle-placed switch cabinet, be negative pressure, from each air inlet supplements cold of middle-placed switch cabinet, and flow through via bus-bar room, make the cooling of whole middle-placed switch cabinet obvious.
In an embodiment, described exhausting assembling is in described pressure release passage therein.In described pressure release passage, avoid exhausting blower fan to the air exhausting outside middle-placed switch cabinet exhausting assembling, improved the air suction efficiency of exhausting blower fan, can make the negative pressure in middle-placed switch cabinet more obvious, reached better cooling-down effect.
Therein in an embodiment, described exhausting assembling in pressure release passage away from one end of pressure release top board.Pressure release top board is dropped to minimum on the impact of exhausting blower fan when the pressure release.
In an embodiment, be also provided with the second air vent hole that is communicated with space outerpace on described pressure release top board therein, the air outlet of described exhausting blower fan is aimed at described the second air vent hole.Make ventilation circuit more rationally, efficiently.
In an embodiment, described middle-placed switch cabinet also comprises the air inlet of three middle-placed switch cabinets therein, and the air inlet of this middle-placed switch cabinet is located at respectively He Hougui top, ,Hou Gui bottom, cable vault.Forward and backward side difference supplements cold from middle-placed switch cabinet, makes ventilation circuit run through whole middle-placed switch cabinet, reaches better cooling-down effect.
Compared with prior art, the utlity model has following beneficial effect:
Middle-placed switch cabinet of the present utility model, exhausting blower fan is changed into and is arranged on rear cabinet bus-bar room top by being arranged on front cabinet top, using the wind path outlet of bus-bar room as the main exit of ventilation circuit, when exhausting blower fan starts, in whole middle-placed switch cabinet, be negative pressure, from each air inlet supplements cold of middle-placed switch cabinet, and flow through via bus-bar room, make the cooling of whole middle-placed switch cabinet obvious.
