Description

A kind of subway transformer radiator and subway transformer

Technical field

The present invention relates to a kind of subway transformer radiator and subway transformer, belong to field transformer.

Background technology

During transformer station high-voltage side bus, heat must dissipate away in time caused by the loss in winding and iron core, in order to avoid overheat And cause insulation damages；For small capacity transformer, external surface area and the ratio between transformer volume are relatively large, can use self cooling Mode, can be dispersed heat by radiation and free convection.But with the continuous development of society, demand of the people to electric power Also it is increasing, especially often work overloadingly in annual winter summer peak times of power consumption, transformer, produce substantial amounts of heat, and The cooling of simple air is often due to the specific heat capacity of gas is smaller, the thermal Finite taken away, it is impossible to which shed transformer generation in time Substantial amounts of heat, transformer will be caused to be stopped or occur transformer damage, or even cause the phenomenon of Explosion of Transformer, not only The production and living of the people have been seriously affected, and also result in the damage of power equipment, have been caused damages to country.In addition, transformation The loss of device is proportional to its volume, so with the increase of transformer capacity, its volume and loss will be with core dimensions three times Fang Zengjia, and the quadratic power increase that its external surface area is only sized, it is therefore, described for high-power transformer iron core and winding Self cooling mode is also difficult to meet its cooling requirement.

The content of the invention

The present invention in view of the above-mentioned problems, provide a kind of subway transformer radiator and corresponding subway transformer, It to high-power or large capacity transformer quick heat radiating, can ensure the normal work of transformer.

The subway transformer radiator includes：Including heat radiation box, it is characterised in that：Left on the surface of babinet The line inlet port of for transformer electricity input and the line outlet of for transformer electricity output；On the surface of babinet, inlet is set And liquid outlet；The transformer is entirely embedded in the babinet, its electric input line connects supply input by the line inlet port, its Electricity output line supplies electricity output by line outlet connection；Coolant enters babinet by the inlet, is produced with the transformer Raw heat carries out heat exchange, and the hot fluid of generation is flowed out by the liquid outlet.

The subway transformer includes：Including babinet and transformer body, it is characterised in that：The transformer body is embedding Enter the box house；The electric input line of the transformer body connects supply input by the line inlet port of the tank surface, Its electricity output line supplies electricity output by the line outlet connection of the tank surface；The surface of the babinet is provided with inlet and goes out Liquid mouth, coolant enter the babinet by the inlet, after carrying out heat exchange with the heat that transformer body produces, generation Hot fluid is flowed out by the liquid outlet.

The inlet is arranged on the latter half of the side surface of the babinet, and the liquid outlet is arranged on the babinet The top half of side surface, so as to improve the heat exchanger effectiveness between coolant and transformer body；Preferably, the inlet The latter half and the top half of two corresponding side surfaces of the babinet are separately positioned on the liquid outlet.

The line inlet port and the line outlet are arranged on the different surfaces of the babinet, in order to electric defeated with transformer Enter line to connect with electricity output line.

To ensure the leakproofness of babinet, sealed after transformer insertion babinet using gasket, its electrical interface uses Waterproofing grade is IP67 electric connections, and the inlet and the liquid outlet are using without leakage non-leakage quick joint after disconnecting It is attached.

The coolant uses non-oil type liquid, it is preferable that has fireproofing function using deionized water, electronics fluorination liquid etc. Coolant, ensure the security of transformer body.

Compared with prior art, the beneficial effects of the present invention are：

Good heat dissipation effect, can radiate high-power or high-power transformer, ensure transformer at a lower temperature Work；Due to the use of coolant there is fireproofing function, additionally it is possible to ensure the security of transformer.

In addition, the user for economic condition difference, it is only necessary to the subway transformer radiator and its accessory are bought, will In the babinet of the whole inserted radiator of transformer and as described above connection wiring, you can to solve the heat dissipation of existing transformer Problem, easy to operate, required expense is also less.
