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 transformer station audible noise measuring is included to transformer station's Main Noise Sources（Main transformer, reactor, ventilation
Blower fan 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 rice, 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 position laying of more than 0.5 meter higher than enclosure wall.
During for station circle's noise testing, the too high phenomenon of enclosure wall, existing solution is using self-control extension rod and extension cable.It is transaudient
Device is connected with sound level meter main frame 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, and microphone can be made can not to cause measurement result inside face enclosure wall
It is inaccurate.Self-control extension rod insulate poor in itself, and plus microphone be metal material and factory is out-of-bounds with a varied topography, if passed during test
Sound device imprudence is encountered 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 microphone, may damage instrument；（3）Tester has strong touch
Inductance, personnel's body and mind is caused to injure.When carrying out noise of equipment measurement using self-control extension rod and extension cable, if microphone is from height
Pressure equipment live part is less than safe distance, it may occur that even more serious electric shock accidents.
The content of the invention
The invention provides a kind of Substation Station circle noise-measuring system, and power transformation can not be ensured by solving existing measurement apparatus
The technical problem of Zhan Zhan circle noise testings accuracy and security.
The present invention is that solve above technical problem by the following technical programs：
A kind of Substation Station circle noise-measuring system, including Substation Station circle enclosure wall, are provided with the outside of Substation Station circle enclosure wall
Noise testing elevating lever, detector installing plate is fixedly installed on the top of noise testing elevating lever, on detector installing plate
Voltage induced alarm, power module and wireless signal transmitter are respectively arranged with, in the top side of noise testing elevating lever
Sound level meter probe is provided with, sound level meter probe links together with wireless signal transmitter, in the bottom of noise testing elevating lever
Insulation clamping seat is provided with, wireless data receipt modules and sound level meter main frame are provided with insulation clamping seat, wireless data receives mould
Block links together with sound level meter main frame.
Instruction handle in direction is additionally provided with the bottom of noise testing elevating lever；Indicate that handle points to one with sound level meter probe
Cause, as long as face enclosure wall can be achieved in 7 face enclosure walls of pinnacled sound level meter probe inwardly in the direction of lower instruction handle.
The present invention can be achieved microphone during the noise testing of Substation Station circle and point to accurately with voltage induced alarm, improve survey
The accuracy and security of amount.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The present invention is described in detail below in conjunction with the accompanying drawings：
A kind of Substation Station circle noise-measuring system, including Substation Station circle enclosure wall, are provided with the outside of Substation Station circle enclosure wall
Noise testing elevating lever 1, detector installing plate 2 is fixedly installed on the top of noise testing elevating lever 1, in detector installing plate
Voltage induced alarm, power module and wireless signal transmitter are respectively arranged with 2, on the top of noise testing elevating lever 1
Side is provided with sound level meter probe 7, and sound level meter probe 7 links together with wireless signal transmitter, in noise testing elevating lever 1
Bottom be provided with insulation clamping seat 3, wireless data receipt modules 5 and sound level meter main frame 6 are provided with insulation clamping seat 3, wirelessly
Data reception module 5 links together with sound level meter main frame 6.
Instruction handle 4 in direction is additionally provided with the bottom of noise testing elevating lever 1；Indicate that handle points to sound level meter probe
Unanimously, as long as 7 face enclosure walls of pinnacled sound level meter probe can be achieved in face enclosure wall inwardly in the direction of lower instruction handle
It is interior.
According to transformer station'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 up of more piece, more than 0.5 meter of transformer station's enclosure wall is higher than after rise, after survey crew reaches measurement place, by package unit
Elevate, make the direction face enclosure wall inwardly of direction instruction handle 4, 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 launched by wireless signal transmitter, the nothing set on insulation clamping seat 3
Line data reception module 5 is transmitted to sound level meter main frame 6 after receiving, and is shown on the liquid crystal display of sound level meter main frame, survey crew
Observe and record station circle's noise data.
