Description
Technical field
The utility model relates to Power Transformer Faults technical field.
Background technology
In electric system, power transformer is most important primary equipment, and power transformer is in operation and will produces a large amount of heats, so power transformer is all equipped with cooling device, wherein most of power transformer cooling device is all equipped with motor, fan, strengthens the radiating effect of refrigeratory.The motor electric loop of current power transformer cooling device has corresponding electric protection measure; but for the physical damage of some motors, fan; as motor bearings damage; electric fan is out of shape, and electric fan scratches the situations such as fan retaining wall, protecting wire net, cannot realize on-line monitoring; except staff checks to scene; the fault of cooling device motor, fan cannot be found at all, cause transformer to dispel the heat thus and badly cause power failure, cause damage to electric power enterprise.
Utility model content
The object of the technical program be overcome the motor of existing power transformer cooling device, fan mechanical fault cannot the shortcoming of on-line monitoring, a kind of device can monitored the mechanical fault of the motor of power transformer transformer cooling device, fan is provided, to process in time, prevent because of motor, fan failure and not safeguarding in time, cause power transformer overheated, and then cause the serviceable life of transformer fault or minimizing power transformer.
The technical program is: the mechanical Fault Monitoring of HV device of a kind of power transformer motor and fan, it is characterized in that, involving vibrations sensor, sensor noise, data acquisition module and surveillance equipment, on the flabellum that vibration transducer is arranged on fan respectively and motor, sensor noise is arranged on the front of motor, vibration transducer and sensor noise and data acquisition module wireless connections, described surveillance equipment comprises data processing module and alarm, the output terminal of data acquisition module is connected with the input end of data processing module, data processing module output terminal is connected with alarm.The vibration signal that vibration transducer and sensor noise collect and voice signal change electric signal into through data acquisition module, be transferred to data processing module again, after data processing module process, electric signal can be converted to waveform, after filtering out the noise signal of transformer body, contrast with the radiating motor of typing prior in data processing module and the noise vibration waveform of fan, when radiating motor and fan normally work, its noise waveform and vibrational waveform are stabilized in certain scope, and amplitude of variation is in certain proportion; Once there is flabellum distortion, or flabellum and fan casing, protecting wire net scratch, or motor bearings damages, the mechanical vibration of corresponding radiating motor, fan and noise also can change, in some cycles, if waveform sudden change is continued above certain proportion, just can judge radiating motor, fan generation mechanical fault, remind staff to carry out examination and maintenance to scene in time.
Preferably, in 10 minutes, if waveform sudden change is continued above 20%, just can judge radiating motor, fan generation mechanical fault.
The beneficial effect adopting technique scheme to produce is: can carry out remote real time monitoring to the mechanical fault of the motor of power transformer transformer cooling device, fan, can Timeliness coverage and prediction radiating motor and the mechanical fault of fan, and send early warning, notify that staff processes, prevent because of motor, fan failure and not safeguarding in time, cause power transformer overheated, and then cause the serviceable life of transformer fault or minimizing power transformer.

Embodiment
The mechanical Fault Monitoring of HV device of a kind of power transformer motor and fan, comprise four vibration transducers, a sensor noise and a data acquisition module, data acquisition module is connected with remote computer, computing machine is connected with alarm, on the flabellum that vibration transducer is bonded in fan respectively and motor, sensor noise is bonded in the front of motor, vibration transducer and sensor noise and data acquisition module wireless connections.Under normal circumstances flabellum 1, flabellum 22, flabellum 33, motor 7 produce mechanical vibration amplitude and noise waveform be metastable, and the Oscillation Amplitude of flabellum 1, flabellum 22, flabellum 33 close to or identical.If flabellum 1, flabellum 22, flabellum 33 deforms or scratches fan casing, protecting wire net, or motor 7 bearing damage, mechanical vibration and noise all can change, now vibration transducer 1, vibration transducer 25, vibration transducer 36, sensor noise 8, the signal that vibration transducer 49 collects changes electric signal into through data acquisition module, be transferred to remote computer again, flabellum is calculated as calculated after machine process, the vibration frequency of motor, cycle and amplitude, the frequency that Real-time Collection is arrived, cycle and amplitude are with the normal data contrast of prerecording storage, in continuous 10 minutes, variation range is more than 20%, computing machine controls alarm and gives the alarm, notify that staff arrives the flabellum 1 of the cooling system of site inspection power transformer, flabellum 22, whether flabellum 33 and motor 7 break down.
The beneficial effect of the technical program is: solve the motor of power transformer cooling system, fan cannot the problem of on-line monitoring, prevent because motor, fan failure barrier, cause power transformer overheated, thus cause the serviceable life of transformer fault or minimizing power transformer.
