The utility model discloses a kind of novel intelligent switchgear house ventilation unit, including control system, and fresh air axial flow blower and temperature sensor in intelligent power distribution room, additionally include the differential pressure pickup of the indoor external differential for measuring intelligent power distribution room, the data output end of the temperature sensor and differential pressure pickup is connected to the data input pin of the control system, and the control signal output of the control system is then connected to the control signal input of the fresh air axial flow blower.The utility model can be realized by forcing air draft to ensure indoor positive pressure and suitable temperature, effectively prevent the hidden danger of apparatus overheat, also a good working environment is created to attendant, while can also effectively keeps indoor cleanliness factor, avoid outside dust from largely entering in switchgear house.
Description
Technical field
It the utility model is related to switchgear house technical field, and in particular to a kind of novel intelligent switchgear house ventilation unit.
Background technology
Switchgear house mainly places high-tension distribution equipment, transformer and low-voltage distribution apparatus, and transmission and power converter process are led
The power consumption of cause can be completely converted into heat, and existing switchgear house typically takes away the partial heat using gravity-flow ventilation, so
And most of switchgear house does not possess good gravity-flow ventilation condition in reality, indoor heat is caused not scatter and disappear in time, to equipment
Operation brings hidden danger, while O＆M operating personnel can not be given to create a friendly environment.
Meanwhile gravity-flow ventilation introduces a large amount of not purified fresh airs, wherein containing substantial amounts of visible grit, change will be caused to match somebody with somebody
A large amount of dust are accumulated inside and out electric equipment, is run steadily in the long term to equipment and brings potential safety hazard, while are unfavorable for operation dimension
The physiological health of shield personnel.
Utility model content
In view of the shortcomings of the prior art, the utility model aims to provide a kind of novel intelligent switchgear house ventilation unit, passes through
Indoor positive pressure and preference temperature are maintained using air draft is forced.
To achieve these goals, the utility model adopts the following technical scheme that：
A kind of novel intelligent switchgear house ventilation unit, including control system, and the fresh air in intelligent power distribution room
Axial flow blower and temperature sensor, additionally include the differential pressure pickup of the indoor external differential for measuring intelligent power distribution room, institute
The data output end for stating temperature sensor and differential pressure pickup is connected to the data input pin of the control system, the control system
The control signal output of system is then connected to the control signal input of the fresh air axial flow blower.
Further, the fresh air axial flow blower is the fresh air axial flow blower with filter screen.
Further, the novel intelligent switchgear house ventilation unit also include warning device be connected to it is described control system
System.
Further, the warning device includes buzzer and GPRS communication module.
The beneficial effects of the utility model are：Pass through fresh air axial flow blower, temperature sensor, differential pressure pickup and control
System coordinates, it is possible to achieve by forcing air draft to ensure indoor positive pressure and suitable temperature, the hidden danger of apparatus overheat is effectively prevented,
Also a good working environment is created to attendant, while can also effectively keeps indoor cleanliness factor, avoid outside dirt
Angstrom largely enter in switchgear house.
Brief description of the drawings
Fig. 1 is principle schematic of the present utility model.
Embodiment
Below with reference to accompanying drawing, the utility model will be further described, it is necessary to which explanation, the present embodiment is with this skill
Premised on art scheme, detailed embodiment and specific operating process are given, but the scope of the utility model is not limited to
The present embodiment.
As shown in figure 1, a kind of novel intelligent switchgear house ventilation unit, including control system, and installed in intelligent power distribution
Indoor fresh air axial flow blower and temperature sensor, additionally include the pressure difference of the indoor external differential for measuring intelligent power distribution room
Sensor, the data output end of the temperature sensor and differential pressure pickup are connected to the data input pin of the control system,
The control signal output of the control system is then connected to the control signal input of the fresh air axial flow blower.
The operation principle of the novel intelligent switchgear house ventilation unit is：The temperature sensor monitors intelligence and matched somebody with somebody in real time
Electric indoor temperature, the differential pressure pickup then monitor the pressure difference of intelligent power distribution indoor and outdoor, the temperature sensor and pressure in real time
Gap sensor is by the data transfer measured to the control system.Control system carries out logic judgment, when in intelligent power distribution room
When the temperature in portion exceedes the pressure difference of design temperature (such as 40 DEG C) or indoor and outdoor less than setting pressure difference (such as 10pa), the control system
System control fresh air axial flow blower starts (closure electric power loop), fresh air axial flow blower air intake, the door and window gap air draft of intelligent power distribution room.
After the temperature of intelligent power distribution chamber interior is less than the pressure difference of design temperature or indoor and outdoor more than setting pressure difference, control system control
The fresh air axial flow blower is (deenergization loop) out of service.
Further, the fresh air axial flow blower is the fresh air axial flow blower with filter screen.Using the new wind axis stream with filter screen
Blower fan can cross the dust in air filtering, play a part of cleaning intelligent power distribution chamber interior.
Further, the novel intelligent switchgear house ventilation unit also include warning device be connected to it is described control system
System.It can set in the controls, when pressure difference of the constant temperature in intelligent power distribution room higher than setting value or indoor and outdoor
During continuously less than setting value certain time, control system control warning device sends alarm signal, notifies administrative staff to check dimension
Repair.
Further, the warning device includes buzzer and GPRS communication module.It is able to can be sent out by buzzer
Go out sound alarm, while can also be sent warning information to intelligent terminal by GPRS communication module, ensure that administrative staff can
To know alarm situation in time.
For those skilled in the art, technical scheme that can be more than and design, provide various corresponding
Change and deformation, and all these change and deformation, should be construed as being included in the utility model claims protection domain it
It is interior.
