It is different in size, rubber cushion aging cracking is caused, leakage point is constantly increased, still, human eye can only be relied on to judge at this stage
Oil droplet drippage quantity in certain time, it is impossible to the accurately specific drippage quantity of record, defect rank is assessed and causes difficulty,
And then bring many difficulties to the safe and stable operation of power network.
《Power transformation primary equipment drawbacks of the standard storehouse》1.1 oil-immersed type transformers, in the definition of oil leak：Oil droplet speed is often dripped
Time is no faster than 5 seconds, and oil level is normally general defect, and oil droplet speed is often dripped the time and is faster than 5 seconds, and oil level normally lacks to be serious
Fall into, oil leak forms oil stream；Oil droplet speed often drips that the time is faster than 5 seconds and oil level is less than lower limit, is crisis defect.Because naked eyes can not
Accurately measure according to the rules, easily cause defect property evaluation inaccurate.Foundation《Defect of transformer equipment administrative standard》
The regulation of 7.3 defect of transformer equipment processing：Urgent defect eliminates in the twenty four hours after discovery.Significant deficiency is after discovery
One month in eliminate.General defect is in three months after discovery or combines the plan that has a power failure and eliminates.If for determining for defect
Justice is inaccurate, can cause defect processing not in time, and then transformer is in the operation of oil starvation state or is run in spite of illness, operating change
The decline of depressor pasta is too low, protection may be caused to malfunction, if transformer oil starvation is serious, internal winding exposure may
Insulation damages are caused, breakdown accident occurs.And the oil pressure at oil leak is less than or equal to oil solution（The oil polluted）Infiltration
During pressure, generation is intermolecular to interpenetrate, and the moisture and gas in air can equally invade fuel tank internal.And one kind is oozed mutually
Saturating process.The reason for transformer communicates with air is poorly sealed, oil leak be present.When transformer is gentle from air inspiration moisture
Body, particularly misty rain weather, once may inspiration large quantity of moisture.The moisture of inspiration makes minor insulation seriously make moist, normal fortune
Just it is enough to cause insulation fault under row voltage.Gas permeation leaves vestige unlike leakage of oil, it is not easy to is discovered, so holding
Easily trigger accident；And accident is once formed, it is exactly transformer or sleeve pipe burning damage accident, harm is especially big.This kind of accident is once sent out
It is raw, gently then cause power equipment damage, tripping operation to stop transport, construction machinery damage, it is heavy then cause casualties.

Wherein, described oil recovery groove is bolted with the interface at rain cover both ends is connected.
Wherein, described oil recovery groove is telescopic annular recess structure, and oil recovery groove is provided with breakpoint, oil recovery groove at breakpoint
Inside be provided with telescopic section less than oil recovery groove diameter, telescopic section is the arc groove structure for being close to oil recovery groove, oil recovery groove
Sealed with telescopic section by sealing ring.
Wherein, described rain cover is telescopic circular ring.
Wherein, described infrared detector will receive the blocking pulse input single-chip microcomputer detected, and single-chip microcomputer is set to inside
Fixed switching switch sends signal, timer and liquid particle counter is started working by switching switch.
Wherein, described liquid particle counter is oil leak oil droplet single channel laser liquid particle collector.
Wherein, described hand switch being spaced apart for manual control, embedded in the side of detection means.
Operation principle of the present utility model is：When operation maintenance personnel or maintainer have found that transformer flange occurs at the scene
During oil leakage phenomenon, the transformer oil drop rate-measuring device is fastened at oil leak, hand switch is pushed into operating position, is connected
Power supply, when oil droplet passes through infrared detector, the detection means is started working, and makes timer and laser liquid by switching switch
Particle collector is started working, and is recorded oil droplet quantity and time, is closed hand switch after terminating.
Compared with prior art, the beneficial effects of the utility model are as follows：Transformer oil drop speed provided by the utility model
Rate detection means is arranged on transformer flange, and has tight rain-proof measure, and defect can be made to prevent in no before processing
Outside liquid or malaria cause secondary injury to transformer.Using laser liquid particle collector and infrared detector,
The numerical value that need to be measured can be more objectively shown, and then makes the judgement of defect rank more accurate, the device has and can stretched
Contracting function, the flange of all kinds of diameters is adapted to, various electric power environmentals can be met.
