Abstract
The invention specifically relates to transformer fan sound monitoring equipment and solves the problem of transformer fan sound monitoring. The transformer fan sound monitoring equipment comprises a central processing module which is arranged at the external part, wherein the central processing module is connected with a sound pickup module arranged on a fan motor stator, in particular an AD (Analog-Digital) conversion module is arranged between the central processing module and the sound pickup module, and the central processing module is further connected with a wireless communication module, a sound uncompressing module, a storage module and a sound comparison module. The transformer fan sound monitoring equipment has the advantages that the operation is simple and convenient to conduct, the equipment is practical and high-efficiency, the monitoring sensitivity is high and the effect of transformer fan fault early warning can be realized.
Description
Technical field
The present invention relates to transformer monitoring device, be specially a kind of transformer fan sound monitoring equipment.
Background technique
In transformer running, the monitoring rate of its fan is more difficult, in existing monitoring technology, often there is following defect: monitor not accurate enough, also not prompt enough.Fan failure easily causes transformer can not proper heat reduction, makes the too high damage of transformer temperature, thus causes serious harm and massive losses to power supply system.The early stage appearance generally understood with noise that transformer fan is breaking down, but there are no the sound monitoring device for transformer fan.
Summary of the invention
The present invention, in order to solve the problem of transformer fan sound monitoring, provides a kind of transformer fan sound monitoring equipment.
The present invention adopts following technological scheme to realize: transformer fan sound monitoring equipment, comprise and be located at outside central processing module, central processing module is connected with the voice pickup module be located on electric fan motor stator, be specially between central processing module and sound pickup model and be provided with AD conversion module, central processing module is also connected with wireless communication module, sound decompression module, memory module and acoustic contrast's module.
Voice pickup module, for picking up fan sound, is specially sound transducer and chip circuit thereof; AD conversion module and analog to digital conversion circuit chip, for being converted to digital signal by the speech simulation collected signal; Sound decompression module, memory module and acoustic contrast's module and central processing module cooperating, complete the decompression of sound signal, storage, and contrast the sound signal of the sound signal newly collected with the normal operation period stored in real time; When audio digital signal difference numerical value is larger, central processing module controls wireless communication module and utilizes short message mode to notify administrative staff.The central processing module wherein used, voice pickup module, wireless communication module, sound decompression module, memory module and acoustic contrast's module are existing chip module, its mutual exchanges data, analog-to-digital conversion, data store and the power supply circuits etc. of modules are prior art, are that those skilled in the art easily realize.
Beneficial effect of the present invention is as follows: the circuit module utilizing appropriate design, achieves the real-time detection of transformer running fan voice data.The present invention in time, effectively can detect the change of fan sound, is unlikely to because the problem of fan causes transformer cisco unity malfunction or transformer damage; The present invention is easy and simple to handle, practicality and high efficiency, sensitive monitoring, can realize transformer fan fault pre-alarming.
