Description
Technical field
The present invention relates to transformer, especially relate to a kind of shell type transformer that utilizes evaporative cooling for heat radiation, shell type transformer can be single-phase, three-phase or heterogeneous shell type transformer, capacity is applicable to compact electrical transformers more than the 10KVA or various special transformer, 10000KVA and above medium-and-large-sized power transformer or various special transformer, line voltage is applicable to 6KV～500KV.
Background technology
Evaporation cooling technique is that a kind of phase transition process that utilizes evaporative cooling medium comes technology that equipment is cooled off, liquid evaporative cooling medium is converted into gas form by liquid form behind the heat that each parts of device interior absorption equipment distribute, gaseous state evaporative cooling medium after the heat absorption (or gas-liquid mixed evaporative cooling medium) arrives heat transferred through condenser extraneous, and the evaporative cooling medium form becomes liquid state again.
The technology of utilizing the phase transition process of evaporative cooling medium device interior to carry out cooling heat dissipation all obtains comparatively ripe application, for example hydraulic generator, turbo generator or the like in some electric equipment fields.Though the transformer technology that some utilize evaporative cooling medium to evaporate to dispel the heat at present also occurred, these technology also exist deficiency in some aspects, have been subjected to some influences in applying.Because transformer is an equipment very high to reliability requirement, and the evaporative cooling medium price of present this evaporation usefulness all compares costliness, and therefore the structure of this transformer is more than the complex structure of common transformer.Liquid in the liquid of common transformer inside and the condenser directly communicates, if damaged the leakage appears in condenser, the evaporative cooling medium in the oil tank of transformer will directly leak in the ambient atmosphere.If detection, malfunctioning again that of monitoring equipment will directly threaten the safety of transformer.And transformer need be through putting into operation after every detection and the debugging work again behind the replacing condenser.
Summary of the invention
The object of the present invention is to provide and a kind ofly adopted that evaporative cooling medium dispels the heat, good airproof performance, condenser and transformer body are independent fully, do not burn, reliability height, radiating efficiency height, condenser are safeguarded the shell type transformer simple, that the evaporative cooling medium consumption is few, volume is little.
The present invention is achieved in that and the present invention includes fuel tank shell, iron core and coil, middle and lower part in the oil pocket of fuel tank shell is placed with iron core and the coil on the iron core, iron core and coil are immersed in the interior oil pocket evaporative cooling medium of oil pocket, sidewall at fuel tank shell is equipped with each phase output lead sleeve pipe, feature is the left bottom at the fuel tank case lid at fuel tank shell top, top in the oil pocket is equipped with interior collector box, the right at the fuel tank case lid, top in the oil pocket is equipped with the evaporator that runs through the fuel tank case lid up and down, interior collector box is communicated with by downcomer with the bottom of evaporator, outside fuel tank shell, be provided with isolated condenser, the left bottom of isolated condenser is communicated with the top of interior collector box by left conduit, the right side wall top of isolated condenser is communicated with isolated condenser by right conduit with the top of evaporator, left side conduit, interior collector box, downcomer, the evaporator and the right conduit looping circulatory system; Collector box outside also being provided with above the fuel tank case lid, outer collector box pass the fuel tank case lid by connecting leg and are communicated with oil pocket.
The present invention adopts and is similar to the structure (comprising shell type core, coil, insulation etc.) that oil becomes shell type transformer, because the space availability ratio of shell type transformer is higher, thereby can reduce the evaporative cooling medium use amount in the fuel tank shell significantly, reduces cost.Fuel tank shell of the present invention is hermetically sealed fuel tank shell, and adopt the structure of this part in the isolated condenser (to see patent for details: 200920141700.7) as required in the relevant position of fuel tank shell (as case lid or tank wall), and each big sealing surface all adopts solder technology weldering dead (comprising lower fuel tank sealing surface, lead-in wire bobbin seal face etc.) in the fuel tank shell, has guaranteed the sealing property of transformer like this; Collector box outside top outside fuel tank shell is provided with, and by the connection of connecting leg oil pocket, like this in the transformer running, the foreign gas that is mingled in the evaporative cooling medium can discharge gradually, because these foreign gases do not participate in heat radiation, therefore also can influence the effect of heat radiation, an outer collector box is set holding these foreign gas, thus the raising radiating effect.External heat sink of the present invention adopts isolated condenser, this isolated condenser oil pocket evaporative cooling medium condenser evaporative cooling medium in the cooling device is complete and oil pocket inside is kept apart, thereby improved the operational reliability of transformer, and the replacing of fault condenser can not have influence on the normal operation of transformer.
The present invention is with respect to present existing other vapour-cooled transformer structure, have good airproof performance, condenser and transformer body fully independent, do not burn, reliability height, radiating efficiency height, condenser safeguard the characteristics simple, that the evaporative cooling medium consumption is few, volume is little, therefore be highly suitable for some have relatively high expectations (such as fire protection requirement high do not fire transformer, buried transformer) occasion be suitable for.Shell type transformer of the present invention can be single-phase, three-phase or heterogeneous shell type transformer, capacity is applicable to compact electrical transformers more than the 10KVA or various special transformer, 10000KVA and above medium-and-large-sized power transformer or various special transformer, line voltage is applicable to 6KV～500KV.
