Embodiment
As shown in Figure 1 to Figure 3, present embodiment discloses a kind of intelligent convergence control cabinet for intelligent substation, mainly comprise cabinet 1, exhaust duct 2, exhaust blower 3, turnover panel component 4, dust cover 5, dust-blocking cover 6, drive damp resistance 7a, heating resistor 7b, protective cover 8.Exhaust duct 2, exhaust blower 3, turnover panel component 4 and dust cover 5 form air exhausting device.Exhaust duct 2 adopts circular duct, and exhaust blower 3 adopts high-power quiet axial flow blower to be fixed in exhaust duct 2.Turnover panel component 4 comprises two pieces of semi-circular plates 41, torsion spring 42 and rotating shaft 42, the length direction two ends on two pieces of semi-circular plate 41 diameter limits are staggered, rotatable to be respectively socketed on rotating shaft 43, on the interlude of rotating shaft 43, cover has torsion spring 42, two terminations of torsion spring 42 push down the upside of two pieces of semi-circular plates 41 respectively, on the rotatable tube wall being fixed on exhaust duct 2 in the two ends of rotating shaft 43, fixed position is in the top of exhaust blower 3 installation site, and the radius of semi-circular plate 41 mates with the radius of exhaust duct 2.
In order to make two of turnover panel component 4 pieces of semi-circular plates 41 be in level when exhaust blower 3 does not work, on the tube wall of exhaust duct 2, the downside place of corresponding two pieces of semi-circular plates 41 arranges catch 9 respectively.
Dust cover 5 comprises circular joint sleeve 51 and is connected to the circular filter net 52 of its upper port, and the upper port inserting exhaust duct 2 with joint sleeve 51 is socketed outward.Cabinet 1 is the closed cabinet of cuboid, its top board 11 offers with the vent of exhaust duct 2 match of pipe diameter, base plate 12 on offer fresh air inlet and cable aperture.Fresh air inlet has two, and shape is strip, and be symmetrically arranged in the length direction both sides of cabinet 1 base plate 12, cable aperture is between two fresh air inlets.There is dodge gate 13 in the forward and backward face of cabinet 1.The lower end of exhaust duct 2 is welded in the vent place on top board.
Dust-blocking cover 6 comprises the framework 61 consistent with fresh air inlet shape, and the inner side of framework 61 is connected with the shutter 62 that certainly hangs down of upwardly-openable, outside is connected with screen pack, and framework 61 welds with the hole wall of fresh air inlet.
The shape of protective cover 8 is umbrella shape, above the top board being welded in cabinet 1 by pillar.Ensure that the maximum cross-section of protective cover 8 corresponds to the middle position of exhaust duct 2 height, to prevent wind and rain sky rainwater from wafing in exhaust duct 2 in cabinet 1, the height of protective cover 8 determines to ensure that the dust cover 5 of smooth loading, unloading exhaust duct 2 upper end is as the criterion.Protective cover 8 also has thermal insulation layer effect, prevents the top of cabinet 1 directly to be shone by sunlight, reduces the temperature in cabinet.
In order to prevent cabinet from causing its internal temperature sharply to rise because of Exposure to Sunlight, in the top of cabinet and side, the outer wall brushing reflection-type of protective cover and exhaust duct or Radiation Heat-insulated Paint.
For the ease of the air intake in cabinet, support column 10 is set in the lower end of cabinet, makes cabinet overhead have certain altitude.
In order to prevent dust and toy from entering in cabinet, the screen pack of dust-blocking cover and dust cover should select the screen cloth that order number is larger.
Heating air in cabinet as early as possible to make to drive tide, heating resistor, will damp resistance and heating resistor be driven be installed on the bottom of cabinet.
Arrange temperature and relative humidity near top exhaust duct in cabinet, the data that epidemic disaster detects realize the automatic switchover of two states after epidemic disaster controller judges.
Specific works process is as follows: work as temperature, when humidity sensor detects that temperature in cabinet is higher than 40 DEG C, temperature, humidity controller can start exhaust blower work automatically, upwards air draft makes two of turnover panel component pieces of semi-circular plates rotate up to open simultaneously, now intelligent convergence control cabinet inside is in negative pressure state, cabinet base plate fresh air inlet place upwardly opens automatically from the shutter that hangs down, outside shady and cool air enters in cabinet, take away after heat through intelligent electronic device, Hot wet air heating is discharged from the exhaust duct at cabinet top, thus the temperature in reduction cabinet ensures intelligent electronic device stable operation.When temperature is lower than 35 DEG C, epidemic disaster controller cuts out exhaust blower automatically, and the turnover panel now in exhaust duct returns to closed condition under the restoring force effect of torsion spring, bottom of cabinet bulk from vertical shutter also due to the automatic sagging closedown without negative pressure in cabinet.When Temperature Humidity Sensor detect temperature in cabinet lower than 5 DEG C or humidity more than 80% time, epidemic disaster controller startup can drive air in tide, heating resistor heating cabinet automatically, prevent condensation from producing, when temperature higher than 15 DEG C or humidity lower than 70% time, temperature and humidity controller automatically can disconnect again and drive tide, heating resistor power supply, stops heating.
By on-the-spot test, when after winter and spring, rain, outside air humidity is larger, the utility model to ensure in cabinet that temperature suitably raises and condensation not occur, and meets intelligent convergence control cabinet temperature requirements simultaneously.When summer, outdoor temperature was very high, the utility model can make the circulation of air present pattern from bottom air inlet, top air-out, realizes in-cabinet temperature lower than outdoor solar light straight solarization temperature more than 10 DEG C; Fully meet desired design target.
