Description
Technical field
The present invention relates to transformer station's technical field, more particularly, to a kind of noise reduction of SF6 electric equipment chambers exhaust system
Method.
Background technology
Substation Operating code provides technical staff before SF6 electric equipment chambers are entered, should be first logical to SF6 electric equipment chambers
Wind 15min.At present, transformer station is aerated generally by way of pipeline+discharge type axial flow blower to SF6 electric equipment chambers
Ventilation and cooling, wherein pipeline is vertically arranged in SF6 electrical equipments room, and its one end is connected with SF6 electric equipment chambers, the other end
It is in communication with the outside behind the top for passing SF6 electric equipment chambers, discharge type axial flow blower is arranged on the other end of pipeline, passes through exhaust
The draft effect of profile shaft flow fan is aerated the purpose taken a breath and cooled to reach to SF6 electric equipment chambers.But in reality
When use, the noise that blower fan running and draft effect are produced can be impacted to the resident around transformer station.
The content of the invention
The present invention is solves the SF6 electric equipment chambers exhaust system that provides of above prior art when in use due to blower fan fortune
Make and noise that draft effect is produced and the technological deficiency that is impacted to the resident around transformer station there is provided a kind of SF6 electricity
The noise-reduction method of gas canyon exhaust system.
To realize above goal of the invention, the technical scheme of use is：
A kind of noise-reduction method of SF6 electric equipment chambers exhaust system, the exhaust system includes pipeline and the exhausting being vertically arranged
Machine, pipeline is vertically arranged in SF6 electrical equipments room, and its one end is connected with SF6 electric equipment chambers, and it is electric that the other end passes SF6
It is in communication with the outside after canyon；Air exhauster is arranged on one end of pipeline by the noise-reduction method, and make the outlet air end of air exhauster with
One end connection and connection of pipeline, then set muffler on pipeline.
Compared with prior art, the beneficial effects of the invention are as follows：
Air exhauster is arranged in SF6 electrical equipments room by the method that the present invention is provided first, and upper exhausting pattern is changed into down and sent
Wind pattern, can reduce the noise of blower fan running and distinguished and admirable generation, furthermore, muffler is set on pipeline, also can be further
The running of ground reduction blower fan and the noise of distinguished and admirable generation.
Brief description of the drawings
Fig. 1 is the front schematic view of exhaust system.
Fig. 2 is the side schematic view of exhaust system.
Embodiment
Accompanying drawing being given for example only property explanation, it is impossible to be interpreted as the limitation to this patent；
Below in conjunction with drawings and examples, the present invention is further elaborated.
Embodiment 1
As shown in Figure 1, 2, exhaust system includes the pipeline 1 and air exhauster 2 being vertically arranged, and pipeline 1 is vertically arranged in SF6 and electrically set
Standby indoor, its one end is connected with SF6 electric equipment chambers, and the other end is in communication with the outside after passing SF6 electric equipment chambers.The present invention is carried
Air exhauster 2 is arranged on one end of pipeline 1 by the noise-reduction method of confession, and make the outlet air end of air exhauster 2 be connected with one end of pipeline 1 and
Connection, then sets muffler 3 on pipeline 1.
Air exhauster 2 is arranged in SF6 electrical equipments room by the method that the present invention is provided first, and upper exhausting pattern is changed into
Lower air supply pattern, can reduce the noise of blower fan running and distinguished and admirable generation, furthermore, muffler 3 is set on pipeline 1, also can
Further reduce the noise of blower fan running and distinguished and admirable generation.
In specific implementation process, as shown in Figure 1, 2, the pipeline 1 include some sections be vertically arranged be sequentially connected
