Description
Technical field
The present invention relates to power transformer emergency service, be specifically related to a kind of power transformer and meet an urgent need heat sink.
Background technology
The safe operation of transformator is played an important role by power transformer radiating and cooling in running.Common power transformer is mainly oil-filled transformer, its main heat sink parts arranged are the radiator that the many groups fin being connected to form by the fin of lamellar is constituted, utilize cross-ventilation Temperature fall and bottom fin install fan blowing accelerate air circulation mode fin is lowered the temperature, this kind of mode disclosure satisfy that the service requirement of transformator under normal conditions；But, summer specific time period continuous high temperature naturalness and the transformer lasts heavy-duty service that causes of the peak of power consumption brought in the case of, oil temperature height enterprise in transformator, original radiating mode cannot meet requirement, for ensureing that transformator can safe operation, traditional way be use and increase radiator fan quantity, below the fin of transformator, place the method such as ice cube lower the temperature, although certain cooling-down effect can be played, but cooling extent is little, speed is slow, the most dangerous the most uneconomical, do not reach the purpose of emergent cooling；Tradition most efficient method is that local power cuts to limit consumption reduces transformer load, but all be unable to do without the epoch of electricity, the act that power cuts to limit consumption is the most feasible in current production, life.
For solving the power transformer radiating and cooling problem at specific time period, the most corresponding auxiliary heat dissipation cooling system or the most common research of device, most commonly seen is that row auxiliary heat dissipation is lowered the temperature by the mode using Water spray by power transformer, if Authorization Notice No. is CN202678050U, invention and created name is the Chinese patent literature of " transformator automatic water-cooling radiator cooler ", i.e. disclose a kind of by pond, water pump, pipeline, spray equipment and the device that transformator is carried out auxiliary temperature-reducing that control device is main composition, its mode used is that sparge pipe is located at the top of transformer body and radiator, direct water-spraying control under having temperature controlled premise；And for example Authorization Notice No. be CN204407140U, invention and created name be the Chinese patent literature of " a kind of power transformer chiller ", it discloses a kind of fixed water tank, two path water pumping system, be arranged on above transformer body the directly shower nozzle of spray and the fin physical contact of the transformator device by compositions such as the water-cooling sheets of circulating water；For another example Authorization Notice No. be CN203165620U, invention and created name be the Chinese patent literature of " a kind of radiating fin of transformer water spray system ", it discloses a kind of by with the shower that pond is connected, be located at the direct device that fin is carried out spraying cooling above fin with shower is connected；The common issue that said apparatus exists is: one, spray head is arranged at the direct Water spray in top of transformer body and/or fin, easily causes transformer top band point parts to be short-circuited so that transformator directly damages；Its two, directly spray with undressed tap water above transformer body and/or fin, easily make transformer body and/or fin corrosion, shorten the service life of transformator；Its three, be the auxiliary device being fixedly installed on transformator periphery, its in actual applications, transformator peripheral space is the most nervous, arranges pond increasingly difficult；And transformator generally only summer specific time period continuous high temperature naturalness and the transformer lasts heavy-duty service that causes of the peak of power consumption brought in the case of, just need to enable auxiliary temperature-reducing facility, the above-mentioned auxiliary device being fixedly installed on transformator periphery increases production cost, economical not.
Authorization Notice No. is CN203433950U, invention and created name is the Chinese patent literature of " power transformer spraying cooling system ", transformator auxiliary temperature-reducing system disclosed in it, consider the water to spray filter and soften, shower water is atomized, it is also proposed scheme shower nozzle can being arranged in the middle of fin simultaneously, it has bigger improvement relative to aforementioned three kinds of devices, but its problem existed has: one, remain as the auxiliary device being fixedly installed on transformator periphery with pond, relatively costly, economical not, can only fix for a certain transformator determined, can not be used as motor-driven meeting an urgent need；Its two, do not consider the impact of use process apoplexy, if working on when wind-force reaches to a certain degree, being likely to result in transformer top band point parts under water (water smoke) wind sprayed out and being short-circuited so that transformator directly damages；Its three, to technical scheme shower nozzle being arranged in the middle of fin, though mentioning, but disclose not quite clear.
