Abstract
The invention provides a transformer cooling device and aims at solving the problem that cooling of cooling fins on an oil-immersed transformer is achieved through heat exchange of the cooling fins and the outside, the speed is low and the overload capacity is limited. The key point is that a water pipe is fixed on the cooling fins of the transformer, a plurality of spray nozzles facing the cooling fins of the transformer are arranged on the water pipe wall, and a water feeding port of the water pipe is connected with a water pump. One blower is placed in the four directions of the periphery of the cooling fins of the transformer respectively and faces the cooling fins of the transformer. The transformer cooling device has the advantages of utilizing a phase transformation principle, remarkably improving the heat exchange speed of a radiator of the transformer and the outside, further improving the overload capacity of the transformer and being low in cost.
Description
Technical field
The present invention relates to a kind of oil-filled transformer, is the cooling device of oil-filled transformer specifically.
Background technology
The current power distribution network of China is rural power grids particularly, transformer significantly overload operation in short time all can appear in special period (during the Spring Festival) every year, in the situation that the certain so significantly overload operation of transformer overload ability can threaten power supply safety.If will be so once in a while significantly the transformer of overload operation all change high-power transformer into, economical not.Improving overload capacity to existing transformer is the most economical way of head it off.By improving the radiating efficiency of transformer, the heat that transformer is produced sheds as far as possible, at the transformer inner accumulation, does not produce high temperature, just can greatly improve the overload capacity of transformer, and radiating effect is directly proportional to overload capacity.All be provided with at present fin on oil-filled transformer, it improves radiating effect by increasing area of dissipation, and the cooling of fin exchanges to realize by itself and external heat, obviously the speed of radiating fin of transformer and air exchange heat is excessively slow, and the rising along with ambient temperature, the speed of exchange can be more and more slower, and then affect the radiating effect (overload capacity) of transformer.For accelerating such exchange, forced guidance oil circulating air cooling and forced guidance oil circulation water-cooling are mature technologies, but these cooling device complexity, cost is high, is not suitable for using in distribution transformer.
Summary of the invention
The objective of the invention is, for improving the speed of radiating fin of transformer and extraneous heat-shift, and then improve the radiating effect (overload capacity) of transformer, a kind of cheapness, efficient pressure swing device cooling device are provided.
The object of the present invention is achieved like this: it comprises radiating fin of transformer, it is characterized in that: fixing water pipe on radiating fin of transformer has several nozzles towards radiating fin of transformer, the filling pipe end water pump of water pipe on water wall; Put a hair-dryer at each face of radiating fin of transformer surrounding, towards radiating fin of transformer.When the transformer overload overheating, water pump and hair-dryer start, nozzle on water pipe is to the jet surface water smoke of transformer radiator, droplet is attached to the surface of transformer radiator equably, vaporized media is provided, and hair-dryer to the surface blowing of radiator, accelerates the vaporization of droplet simultaneously, phase by droplet transforms, and the spreader surface heat is taken away.
Compared with prior art, good effect of the present invention is: it has utilized the principle of phase change procedure heat absorption, improved significantly the speed of transformer radiator and extraneous heat-shift, and then improved the overload capacity of transformer, and this device is with low cost.
The accompanying drawing explanation
Further illustrate the present invention below in conjunction with accompanying drawing.
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the A section enlarged drawing of Fig. 1.
Fig. 4 is the B-B profile of Fig. 2.
Embodiment
For the heat that coil is produced is delivered to spreader surface, the present embodiment also is provided with the device of simple type forced guidance oil circulation, specifically, lay 50 high temperature resistant oil resistant flexible pipes below transformer radiator inside, after parallel connection as oil pick-up tube 9,7 li of coils, fuel-displaced flexible pipe 8 is set, one end of oil pick-up tube and fuel-displaced flexible pipe inserts respectively oil-in and the oil-out of oil circulating pump 5, oil circulating pump is sent to the heat coil surface by the cooled transformer oil in radiator, forcing the formation convection current, is the coil cooling.
