Description
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, its arrange main heat sink part be by sheet fin be connected to form it is many
The radiator that group fin is constituted, the blowing that fan is installed using cross-ventilation Temperature fall and in fin bottom accelerates empty
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, transformer lasts high load capacity is transported caused by the nature and its peak of power consumption brought of summer specific time period continuous high temperature
In the case of row, oil temperature height enterprise in transformer, original radiating mode can not meet requirement, to ensure that transformer can be transported safely
OK, traditional way is to place the methods such as ice cube using the quantity of increase radiator fan, below the fin of transformer to carry out
Cooling, although certain cooling-down effect can be played, but cooling extent is small, speed slow, and both dangerous or uneconomical, not reaching should
The purpose for the temperature that plunges;Traditional most efficient method is local power cuts to limit consumption reduction transformer load, but 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

Device is directly damaged;Second, easily making 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, being 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 caused by the nature and its peak of power consumption brought of summer specific time period continuous high temperature by transformer
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 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 in the middle of fin, it has relative to foregoing three kinds of devices
Larger improvement, but it has the problem of exist:First, remaining as the auxiliary for the being fixedly installed on transformer periphery dress with pond
Put, cost is higher, it is 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 be likely to result in transformer top band point part occur short circuit so that transformer is directly damaged;Third, scattered to shower nozzle is arranged on
Technical scheme in the middle of backing, though referring to, is disclosed unknown.

Work is temporarily ceased, is restarted when the real-time wind speed that air velocity transducer 64 is detected is less than the threshold values that PLC main control modules are set
Work, effectively to prevent from damaging transformer because wind senior general's water smoke is blown to short circuit occurs for transformer top band point part;If pressure
When the water smoke pressure that sensor 62 is detected in the water outlet pipeline of electric water pump 3 reaches the threshold values of PLC main control modules setting, phase
Alarm lamp is answered to light, PLC main control modules make water smoke pressure reach properly by the power of frequency conversion adjust automatically electric water pump 3
Level, to ensure stainless steel water-main 52, stainless steel spray branch pipe 53 and the trouble free service of atomizer 8.
The present apparatus can also switch to the artificial control operation of hand-held block by hand control switch 43, be switched to manual control
During pattern, compulsory mist cooling can be carried out to radiating fin of transformer 9 at any time or its stopping is sprayed.
To sum up, the emergent heat sink of the power transformer of the present embodiment, it is by the way that water tank, electric water pump and Main Control Tank are set
Put on movable base, water inlet pipe has adopted hose so that its mobility strong, be easy to Emergency use transport and live finite field
The flexible arrangement on ground, can Reusability, strong applicability and compared to solid in every transformer in the prior art as emergency set
A set of heat sink used once in a while is set surely, cost can be greatly lowered, it is good in economic efficiency;It passes through per adjacent 2
It is each between radiating fin of transformer to set 1 stainless steel to spray branch pipe;Be uniformly arranged respectively on every stainless steel spray branch pipe 4 to
10 atomizers, each atomizer is set downwards in the way of horizontal by 45 degree of angles;Each atomizer with it is corresponding
The distance between radiating fin of transformer be 2/3 of distance between 2 adjacent atomizers;Height of each atomizer apart from ground
2/3 and atomizer for radiating fin of transformer height are spent using nozzle of fine steam droplet for spraying 4 μm -15 μm etc.
Design, on the one hand can effectively prevent water smoke to be sprayed onto transformer top band point part and occur short circuit and damage transformer;On the other hand
So that the fine steam droplet for 4 μm -15 μm sizes that atomizer sprays is rapidly diffused into around radiating fin of transformer during work
Air and be adsorbed onto on the surface of radiating fin of transformer, in absorption air and fin surface heat, rapidly from liquid become
Heat is taken away into gaseous state, cooling rate is fast, effect is good;And can effectively prevent radiating fin of transformer ponding corrosion;Effective gram
Having taken similar device in the prior art easily causes transformer top band point part to occur Damage by Short Circuit transformer and easily cause
Transformer body and/or the major defect of fin corrosion;It is by setting the air velocity transducer being connected with main controller, it is considered to wind
Factor, the present apparatus cooling course of work in, if the real-time wind speed detected reaches the threshold values of setting, automatic pause work
Make, effectively to prevent from damaging transformer because wind senior general's water smoke is blown to short circuit occurs for transformer top band point part, further protect
Hinder the operation safety of transformer;The heat sink moreover, power transformer of the present embodiment is met an urgent need, simple in construction, cost is relatively low, section
Water is saved.
Above example is the explanation of the embodiment to the present invention, rather than limitation of the present invention, relevant technology
The technical staff in field without departing from the spirit and scope of the present invention, can also make various conversion and change and obtain
To corresponding equivalent technical scheme, therefore all equivalent technical schemes should be included into the patent protection model of the present invention
Enclose.
