Description
The application is Application No. 201610310513.1, and the applying date is on May 22nd, 2016, and invention and created name is
The divisional application of the application for a patent for invention of " power transformer meet an urgent need heat sink ".
Technical field
The present invention relates to power transformer emergency service, and in particular to a kind of power transformer is met an urgent need heat sink.
Background technology
Safe operation of the radiating and cooling of power transformer in the process of running to transformer plays an important role.Common
Power transformer is mainly oil-filled transformer, and its main heat sink part arranged is more to be connected to form by the fin of sheet
Sky is accelerated in the radiator that group fin is formed, the blowing that fan is installed using cross-ventilation Temperature fall and in fin bottom
The mode of gas circulation cools to fin, and such a mode disclosure satisfy that the service requirement of transformer under normal conditions；So
And the transformer lasts high load capacity caused by the nature and its peak of power consumption brought of summer specific time period continuous high temperature is transported
In the case of row, the high enterprise of oil temperature, original radiating mode can not meet to require in transformer, to ensure that transformer can be transported safely
OK, traditional way is to be carried out using the quantity of increase radiator fan, below the fin of transformer the methods of placement ice cube
Cooling, although certain cooling-down effect can be played, cooling extent is small, speed is slow, both dangerous or uneconomical, and not reaching should
The purpose for the temperature that plunges；Traditional most efficient method is that local power cuts to limit consumption reduces transformer load, but equal in current production, life
It is unable to do without the epoch of electricity, power cuts to limit consumption feasible act easily absolutely not.
To solve the problems, such as radiating and cooling of the power transformer in specific time period, at present corresponding auxiliary heat dissipation cooling system or
Device common research, most commonly seen is that power transformer is cooled to row auxiliary heat dissipation by the way of Water spray, is such as awarded
The Chinese patent literature that notification number is CN 202678050U, invention and created name is " transformer automatic water cooling device " is weighed, i.e.,
Disclose and a kind of auxiliary temperature-reducing is carried out to transformer by what is formed based on pond, water pump, pipeline, spray equipment and control device
Device, it is located at the top of transformer body and radiator, on the premise of having temperature control by the way of by sparge pipe
Direct water-spraying control；And for example Authorization Notice No. be CN 204407140U, invention and created name be a kind of " power transformer cooling
The Chinese patent literature of device ", it discloses a kind of fixed water tank, two-way water pump system, it is arranged on above transformer body
The dress of the compositions such as the water-cooling piece that the fin physical contact of the shower nozzle and transformer that directly spray passes through circulating water
Put；For another example Authorization Notice No. be CN 203165620U, invention and created name be " a kind of radiating fin of transformer water spray system "

The direct Water spray in the top of device body and/or fin, easily cause transformer top band point part that short circuit occurs so that transformation
Device directly damages；Second, easily make directly with undressed originally Water spray in the top of transformer body and/or fin
Transformer body and/or fin corrosion are obtained, shortens the service life of transformer；Third, it is to be fixedly installed on transformer week
The servicing unit on side, its in actual applications, transformer peripheral space is often more nervous, set pond it is increasingly difficult；And
Transformer generally only hold by the transformer caused by the nature and its peak of power consumption brought of summer specific time period continuous high temperature
In the case of continuous heavy-duty service, just need to enable auxiliary temperature-reducing facility, the above-mentioned auxiliary dress for being fixedly installed on transformer periphery
Increase production cost is put, it is not economical enough.
Authorization Notice No. is CN 203433950U, invention and created name is in " power transformer spraying cooling system "
State's patent document, its disclosed transformer auxiliary temperature-reducing system, it is contemplated that the water of spray is filtered and softened, to spray
Water is atomized, while it is also proposed the scheme that can be arranged on shower nozzle among fin, and it has relative to foregoing three kinds of devices
Larger improvement, but have the problem of it is present：First, remain as the auxiliary for the being fixedly installed on transformer periphery dress with pond
Put, cost is higher, not economical enough, can only fixed pin to the transformer of a certain determination, it is impossible to emergent be used as motor-driven；Second,
The influence using process apoplexy, if being worked on when wind-force reaches to a certain degree, the water sprayed out are not considered（Water smoke）Wind
Under may cause transformer top band point part occur short circuit so that transformer directly damages；It is third, scattered to shower nozzle is arranged on
Technical scheme among backing, though referring to, disclose unknown.
