Description
Technical field
The utility model belongs to field of environment engineering technology, is specifically related to a kind of low-noise energy-saving ventilation unit that can use in indoor substation or box type transformer one class indoor electric equipment.
Background technology
For guaranteeing indoor electric equipment, the safe operation of for example indoor substation or box type transformer, indoor substation or box type transformer all must ventilation and heat.Known indoor substation and the heat radiation of box type transformer and draft type are, within ambient, cool air enters indoor substation or box type transformer by air inlet or noise elimination blinds.And indoor hot-air drives the air outlet of discharging air outlet or adding muffler to get integrated into environment by outlet air channel by blower fan.This traditional ventilation and heat method, is to enter indoor cold air, with in indoor substation or the electric equipment that in box type transformer, temperature is higher carry out the hot-air becoming after convection heat exchange, all discharge by air outlet, air drag is larger.Therefore, in the time that the ambient temperature at winter or night reaches indoor substation or box type transformer and can adopt air themperature to reach the condition that can implement natural ventilation system, but often cause blower fan Non-intermittent excess load to move continuously because of the resistance increment that blower fan meets with, so, increase energy consumption, the noise pollution environment producing because of blower fan again.Especially night, is not singly contaminated environment, or even serious disturbing residents.
Utility model content
The technical problems to be solved in the utility model is: for the defect of prior art, provide a kind of low-noise energy-saving ventilation unit.In indoor substation or box type transformer one class indoor electric equipment, use this device, can guarantee indoor substation and box type transformer security of operation, capable of reducing energy consumption again, reduce noise emissions, protection of the environment.
The technical solution of the utility model is that, referring to accompanying drawing 1, the low-noise energy-saving ventilation unit providing as shown in Figure 1, forms by the air pipe 4 of temp probe 1, single-chip microcomputer combined control equipment 2, charged damper 3 with the ventilation blower fan 6 of muffler 5.The signal input part of wherein said single-chip microcomputer combined control equipment 2 is connected with the signal output part of described temp probe 1.The control end of described single-chip microcomputer combined control equipment 2 be connected in parallel the motor switch control end of 4 charged dampers 3 of described air pipe and the motor switch control end with the ventilation blower fan 6 of muffler 5.4 charged dampers 3 of wherein said air pipe are radially arranged in this air pipe 4.The air intake of ventilation blower fan 6 connects and is connected with the air intake of air pipe 4, and the outlet air end of air pipe 4 connects and is connected with the air intake of described muffler 5.The outlet air end of described muffler 5 connects and is connected with the outlet air end of described ventilation blower fan 6.
While use by the low-noise energy-saving ventilation unit of the present utility model forming above, only this device need be installed on electric equipment and the sealing chamber internal upper part with air inlet are housed, or be placed in and be equipped with in electric equipment and the closed box with air inlet, the outlet air end of air pipe 4 is led to outdoor, can start the single-chip microcomputer combined control equipment 2 of this device in the time receiving that temp probe 1 surpasses the signal of design temperature, by closing automatically controlled air door 3 and starting the temperature that ventilation blower fan 6 comes in conditioning chamber or in casing.Otherwise; if the single-chip microcomputer combined control equipment 2 of this device is receiving that temp probe 1 is not when the signal of super design temperature; by opening automatically controlled air door 3 and closing ventilation blower fan 6 and realize natural draft to reduce air drag; reduce 6 running times of blower fan; thereby reduction energy consumption; reduce the discharge of noise, protection of the environment.
The beneficial effects of the utility model are:
1) air drag, can reduce indoor substation or box type transformer one class indoor electric equipment natural draft time, improves effect of natural ventilation, reduces the fan operation time, thereby reduces energy consumption, reduces the noise emissions of fan operation, protection of the environment;
2), simplicity of design, safe and reliable, small investment, environmental protection, economic benefit is obvious;
3), can mate the ventilation and heat facility of multiple indoor electric equipment or box electric equipment, for the safe operation of multiple electric equipment provides safeguard.
