According to the utility model, the sound sensor is arranged on the lead insulating layer of the low-voltage power transmission line, and used to collect sounds emitted by fault arc, and the sounds are processed by the processing module and then displayed on the display screen in the monitoring room, so that the fault arc of the low-voltage power transmission line is monitored in real time, and another fault arc detection manner is provided; and thus, the hidden safety troubles are reduced, accidents are avoided, and the working efficiency can be improved.
Description
Technical field
The utility model relates to a kind of fault arc detection device, relates in particular to a kind of fault arc detection device based on sonic detection.
Background technology
In the use procedure of low-voltage electrical transmission line of electricity, often because the reasons such as overload, mechanical damage, humidity cause the aging or destruction of the insulation course of low-voltage electrical transmission line of electricity, thereby cause between transmission line of electricity and the earth or circuit and circuit and produce electric discharge phenomena, in the time of electric discharge, can produce strong fault electric arc.Once fault electric arc occurs, and just can give off huge sound, optical, electrical, hot homenergic, cause electric system and consumer breaking-up, casualties, there is huge potential safety hazard.
At present, traditional fault arc detection method mostly arc light or the current signal based on fault electric arc is produced carries out Real-Time Monitoring, tends to, because circuit is subject to all restrictions in use compared with long or other reasons, reduce work efficiency.
Utility model content
The purpose of this utility model is to provide a kind of fault arc detection device based on sonic detection, the sound that can send when fault electric arc is produced detects, the real-time monitoring of realization to low-voltage electrical transmission line malfunction electric arc, reduces potential safety hazard, increases work efficiency.
The utility model adopts following technical proposals:
A kind of fault arc detection device based on sonic detection, comprise the sound transducer being arranged on low-voltage electrical power line conductive line insulating layer, the signal output part of sound transducer connects the signal input part of processing module, and the display output terminal of processing module connects the signal input part of the display screen that is arranged on Control Room.
The signal output part of described sound transducer connects the signal input part of processing module by wired or wireless mode.
Described sound transducer is arranged in sound transducer fixed bin, is provided with high temperature resistant strapping on sound transducer fixed bin.
Described sound transducer fixed bin surface offers a plurality of sound monitoring holes.
Described high temperature resistant strapping is divided into band body and pricks a body, and band body and a bundle body are Y-shaped, and band body lower surface is provided with hangnail, and band body bottom is free end, and the Liang Ge branch on band body top is separately fixed at sound transducer fixed bin one side; Prick a body bottom and be provided with buckle, the Liang Ge branch of pricking a body top is separately fixed at the opposite side of sound transducer fixed bin.
Described high temperature resistant strapping is made by nylon six or six materials.
The utility model by arranging sound transducer on low-voltage electrical power line conductive line insulating layer, utilize sound transducer to gather the sound sending when fault electric arc produces, and show on the display screen of Control Room by control module, can realize the real-time monitoring to low-voltage electrical transmission line malfunction electric arc.The utility model provides another kind of fault electric arc detection mode, can reduce potential safety hazard, avoids occurring security incident, can also increase work efficiency simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of sound transducer fixed bin.
Embodiment
As shown in Figure 1, the utility model comprises the sound transducer 2 being arranged on low-voltage electrical transmission line wire 10 insulation courses 11, the signal output part of sound transducer 2 connects the signal input part of processing module 12 by wired or wireless mode, the display output terminal of processing module 12 connects the signal input part of the display screen 13 that is arranged on Control Room.When low-voltage electrical transmission line of electricity has fault electric arc to produce, follow the generation of fault electric arc will send huge sound.Because low-voltage electrical transmission line wire 10 is metallic conductor, it is the good conductor of sound, therefore, the sound that fault electric arc sends while producing will be collected by sound transducer 2, and send to processing module 12 by wired or wireless mode, 12 pairs of voice signals of processing module are processed, and show by the display screen 13 of Control Room, to reach the real-time monitoring to low-voltage electrical transmission line malfunction electric arc.
For the ease of sound transducer 2 is fixed, the utility model also has additional the sound transducer fixed bin 1 that a plurality of sound monitoring holes are offered on surface.Sound transducer 2 is arranged in sound transducer fixed bin 1, is provided with the high temperature resistant strapping of being made by nylon six or six materials on sound transducer fixed bin 1.Nylon six or six materials have higher resistance to elevated temperatures, can be in hot environment continuous firing, stop to occur the aging phenomenon of rupture of strapping.High temperature resistant strapping is divided into band body 3 and pricks a body 4, and band body 3 and a bundle body 4 are Y-shaped, can guarantee the fastness and the stability that are connected with sound transducer fixed bin 1.Band body 3 lower surfaces are provided with hangnail 5, and band body 3 bottoms are free end 6, and the Liang Ge branch 7 on band body 3 tops is separately fixed at sound transducer fixed bin 1 one sides; Prick a body 4 bottoms and be provided with buckle 8, be provided with the latching device that allows 3 one-way movements of band body in buckle 8, the Liang Ge branch 9 of pricking a body 4 tops is separately fixed at the opposite side of sound transducer fixed bin 1.
Above embodiment is only a kind of preferred implementation of the present utility model, but the utility model is not limited to above-mentioned embodiment.It in the ken possessing at described field those of ordinary skill, any modification of doing within spirit of the present utility model and principle, is equal to and substitutes and improvement etc., within all should be encompassed in the technical scheme scope that the utility model asks for protection.
