Description
Technical field
The present invention relates to a kind of noise-measuring system, more particularly to a kind of Substation Station circle noise-measuring system.
Background technology
High-voltage alternating substation audible noise measuring is included to substation's Main Noise Sources（Main transformer, reactor, ventilation
Wind turbine etc.）, Work places and stand boundary's audible noise measurement.At present, 500kV and 1000kV Substation Stations circle enclosure wall generally compared with
Height, up to 4-6 meters, and high voltage pulse electronic enclosure is housed above enclosure wall.According to pertinent regulations, Dang Changjie has enclosure wall and surrounding has
During impacted noise-sensitive structure, noise measuring point need to be out-of-bounds 1 meter in factory, and is laid higher than the position of 0.5 meter of enclosure wall or more.
During for station circle's noise testing, the phenomenon that enclosure wall is excessively high, existing solution is using self-control extension rod and extension cable.It is transaudient
Device is connected with sound level meter host using extension cable, and the hollow parts of extension cable from self-control extension rod run through into.Self-control is prolonged
Stock is combined by simple grafting, is easily rocked when reaching eminence, can make microphone that can not cause measurement result inside face enclosure wall
It is inaccurate.Self-control extension rod insulate in itself it is poor, in addition microphone is metal material and factory is out-of-bounds with a varied topography, if passed during test
Sound device accidentallys run into or too close to fence, following consequence can be caused to occur：（1）Fence can send wrong report
Alert, cause the accident wrong report；（2）Fence can discharge to microphone, may damage instrument；（3）Tester has strong touch
Inductance causes personnel's body and mind to injure.When carrying out noise of equipment measurement using self-control extension rod and extension cable, if microphone is from height
Equipment live part is pressed to be less than safe distance, it may occur that even more serious electric shock accidents.
The content of the invention
The present invention provides a kind of Substation Station circle noise-measuring systems, and power transformation can not be ensured by solving existing measuring device
The technical issues of Zhan Zhan circle noise testings accuracy and security.
The present invention is to solve more than technical problem by the following technical programs：
A kind of Substation Station circle noise-measuring system, is provided with noise testing elevating lever on the outside of Substation Station circle enclosure wall,
Detector installing plate is fixedly installed on the top of noise testing elevating lever, voltage sense is respectively arranged on detector installing plate
Alarm, power module and wireless signal transmitter are answered, sound level meter probe is provided in the top one side of noise testing elevating lever,
Sound level meter probe links together with wireless signal transmitter, and the bottom of noise testing elevating lever is provided with insulation clamping seat,
Wireless data receipt modules and sound level meter host are provided on insulation clamping seat, wireless data receipt modules are connected with sound level meter host
Together.
Direction instruction handle is additionally provided in the bottom of noise testing elevating lever；Indicate that handle is directed toward one with sound level meter probe
It causes, as long as face enclosure wall can be realized pinnacled sound level meter and pop one's head in 7 face enclosure walls inwardly in the direction instruction handle of lower.
The present invention can be achieved microphone during the noise testing of Substation Station circle and be directed toward accurately with voltage induced alarm, improve survey
The accuracy and security of amount.
Description of the drawings
Fig. 1 is the structure diagram of the present invention.
Specific embodiment
The present invention is described in detail below in conjunction with the accompanying drawings：
A kind of Substation Station circle noise-measuring system, is provided with noise testing elevating lever 1 on the outside of Substation Station circle enclosure wall,
Detector installing plate 2 is fixedly installed on the top of noise testing elevating lever 1, electricity is respectively arranged on detector installing plate 2
Pressure sensitivity answers alarm, power module and wireless signal transmitter, and the top one side of noise testing elevating lever 1 is provided with sound level meter
Probe 7, sound level meter probe 7 link together with wireless signal transmitter, and the bottom of noise testing elevating lever 1 is provided with insulation
Deck 3 is provided with wireless data receipt modules 5 and sound level meter host 6, wireless data receipt modules 5 and sound on insulation clamping seat 3
Grade meter host 6 links together.
Direction instruction handle 4 is additionally provided in the bottom of noise testing elevating lever 1；Indicate that handle is directed toward with sound level meter probe
Unanimously, as long as face enclosure wall can be realized pinnacled sound level meter and pop one's head in 7 face enclosure walls inwardly in the direction instruction handle of lower
It is interior.
According to substation's enclosure wall height and situation on the spot, noise testing elevating lever 1, general noise testing elevating lever 1 are selected
It is made of more piece, 0.5 meter of substation's enclosure wall or more is higher than after rise, after survey crew reaches measurement place, by package unit
It elevates, makes the direction of direction instruction handle 4 face enclosure wall inwardly, start noise testing.In the process, if sound level meter is popped one's head in
7 near the high voltage pulse electronic enclosure on enclosure wall when, voltage induced alarm will alarm, remind survey crew pay attention to pacifying
Entirely.The noise signal that sound level meter probe 7 detects can be emitted by wireless signal transmitter, the nothing set on insulation clamping seat 3
Line data reception module 5 is transmitted to sound level meter host 6 after receiving, and is shown on the liquid crystal display of sound level meter host, survey crew
Observe and record station circle's noise data.
