The form that contrasts of the operating ambient temperature value that the present embodiment provides a kind of blower fan and the life consumption time of lubricating grease, wherein, in form, data are calculated and are obtained according to n/N=0.25 and P/Cr=0.1, specifically referring to table 1:
Table 1
As can be seen from Table 1, when blower fan is operated in different ambient temperatures, the life consumption asynchronism(-nization) of lubricating grease, therefore, referring to above table, the operating ambient temperature value of blower fan can be converted into to the life consumption time of lubricating grease, from blower fan turns round for the first time, by blower fan in each running time residing operating ambient temperature value all be converted into life consumption time of lubricating grease, and added up, can obtain the life consumption cumulative time of lubricating grease, because the life-span of blower fan is depended on life-span of lubricating grease, so can realize the prediction to fan life, thereby the staff can adopt an effective measure in time, avoid the generation of unnecessary accident.
What need explanation is a bit, the present embodiment to life consumption time of lubricating grease cumulative, be in the situation that blower fan in running, be understandable that, when blower fan does not turn round, impact due to other factors, the residing ambient temperature of lubricating grease for example, lubricating grease also has certain life consumption, think the accuracy increased the fan life prediction, when processor 13 can also be pre-stored with blower fan and not turn round, the life consumption time of lubricating grease, for example, when blower fan does not turn round, the life consumption time of lubricating grease is 0.5hrs, the life consumption time of the lubricating grease therefore finally obtained, the life consumption time of lubricating grease when the life consumption time of lubricating grease and blower fan off-duty in the time of can comprising fan operation.
It is well known to a person skilled in the art that the operating ambient temperature value of the blower fan that wherein, processor 13 foundations are obtained obtains the processing procedure of the life consumption time of lubricating grease.
On basis embodiment illustrated in fig. 1, referring to Fig. 2, the embodiment of the invention discloses the structural representation of another kind of fan life prediction unit, from embodiment illustrated in fig. 1 different, the present embodiment can also comprise: alarm 14;
The input end of alarm 14 is connected with the first output terminal of processor 13, when the cumulative life time of lubricating grease surpasses the default life time of described lubricating grease of processor 13 prestor, alarm 14 is reported to the police according to the alarm signal of processor 13 outputs of obtaining.Therefore, after alarm 14 is reported to the police, the staff can adopt an effective measure (as blower fan changed or being safeguarded) in time, improves the working life of blower fan, thereby reaches the requirement of transformer to operational reliability.
What need explanation is a bit, when dispatching from the factory, blower fan determines the working life of lubricating grease (being initial value), after alarm 14, for to the staff, replacing or the maintenance of blower fan being left to the sufficient time, default life time that can lubricating grease is set to 90% of initial value.
Wherein, alarm 14 can be buzzer or warning light.
Be understandable that, when the operating ambient temperature of blower fan is too high, blower fan just easily breaks down in running, therefore, for reducing the generation of fan trouble, the interior preset temperature value (being the maximum temperature values of blower fan safe operation) that can also store blower fan of processor 13, when the operating ambient temperature of blower fan surpasses the preset temperature value of blower fan, processor 13 is controlled alarm 14 and is reported to the police, thereby the staff is adopted an effective measure in time, avoid affecting because of fan trouble the stable operation of transformer.
For further optimizing technique scheme, the present embodiment can also comprise: display device 15;
The input end of display device 15 is connected with the second output terminal of processor 13, the default life time of the lubricating grease that display device 15 can video-stream processor 13 prestor and the cumulative life time of lubricating grease.
Therefore, the staff can be clearly seen that the life situations of fan operation by display device 15, judges in advance whether blower fan needs changed or safeguard, thereby improves the life-span of blower fan.
Be understandable that the operating ambient temperature value in the time of can also showing the blower fan running on display device 15.
Preferably, display device 15 can be touch screen controller.
Need explanation a bit, in above-mentioned each embodiment, on processor 13, can be provided with communication interface, processor 13 can send the operating ambient temperature value of the cumulative life time of lubricating grease and blower fan to extraneous reception unit.
Wherein, fan life prediction unit provided by the invention can be used as an independently instrument, also can be used as partial function and other devices integrate.
In summary it can be seen, the natural hour number that the present invention moves blower fan under any operating ambient temperature, be converted into the life consumption time of lubricating grease, and accumulative total obtains total life consumption time of lubricating grease, be the life consumption time of blower fan, realized the prediction to fan life, by judging in advance blower fan, whether need replacing or maintenance etc., improve the working life of blower fan, reach the requirement of transformer to operational reliability.
In this specification, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is and other embodiments' difference that between each embodiment, identical similar part is mutually referring to getting final product.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the present invention.Multiple modification to these embodiments will be apparent for those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from the spirit or scope of the present invention, realization in other embodiments.Therefore, the present invention will can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
