Abstract
The present invention discloses a kind of main transformer physical cooling method, and one layer of hydrophily, ageing-resistant, colourless or white organic short fiber layer are sprayed by electrostatic flocking technology on the surface of the surface of main transformer, especially radiating fin；In the lower section of main transformer, Storage water tank is set, the fixed ultrasonic generator that can be made water fogging in side of the Storage water tank, the water inlet pipe of the ultrasonic generator is extend into the Storage water tank, the one or more fog floss hole of the ultrasonic generator is arranged on the top of the main transformer, and the fog for discharging ultrasonic generator is shrouded on the surface of whole main transformer.Compare compared with prior art, the present invention can greatly increase the heat removal surface area of main transformer in the surface spraying organic short fiber layer of main transformer, and the adsorbable substantial amounts of Mini-type water drop of hydrophily organic short fiber layer, substantial amounts of heat can be taken away when water droplet evaporates.
Description
Technical field
The present invention relates to electrical circuitry equipment technical field, is specifically a kind of main transformer physical hypothermal device.
Background technology
Summer is mean temperature highest season in 1 year, at the same be also cooling load and irrigate electricity consumption peak period, three
The superposition of kind factor, causes power grid power load constantly soaring, certain pressure, especially main transformer is brought to grid operation equipment
Depressor high oil temperature, certain risk is brought to operation of power networks.
The patent of invention of Publication No. CN103794336A discloses a kind of main transformer heat sink, it includes conduit,
Nozzle is equipped with conduit water outlet, conduit is equipped with valve, force (forcing) pump is equipped with water injection through pipe mouth.The nozzle uses shower
Nozzle.Using effect of the present invention is preferable, can effectively cool down to main transformer, ensure that the normal of main transformer makes
With.But since main transformer surface does not have adsorptivity to moisture, being sprayed at the major part on main transformer surface can flow on the ground, only
A small amount of moisture can be retained, simultaneously because summer transpiration is very fast, main transformer surface that point point moisture will soon evaporate
Totally, cooling-down effect is bad.
The content of the invention
The purpose of the present invention is overcoming the deficiencies of the prior art and provide a kind of main transformer physical cooling method, taken
Technical solution be：
A kind of main transformer physical cooling method, it is characterised in that：On the surface of the surface of main transformer, especially radiating fin
One layer of hydrophily, ageing-resistant, colourless or white organic short fiber layer are sprayed by electrostatic flocking technology；Under main transformer
Side's setting Storage water tank, the fixed ultrasonic generator that can be made water fogging in side of the Storage water tank, the ultrasonic generator
Water inlet pipe is extend into the Storage water tank, and the one or more fog floss hole of the ultrasonic generator is arranged on institute
The top of main transformer is stated, and the fog for discharging ultrasonic generator is shrouded on the surface of whole main transformer.
Further, in the fixed temperature detect switch (TDS) in the surface of main transformer, when the surface degree of the main transformer is higher than
During temperature range set by the temperature detect switch (TDS), the circuit turn-on powered to the ultrasonic generator is controlled, when the main transformer
When the surface degree of depressor is less than the temperature range set by the temperature detect switch (TDS), the circuit powered to the ultrasonic generator is controlled
Cut-off.It can so automatically control, reduce consumption.
Further, a water supply installation being automatically replenished to the Storage water tank is further included.It can be achieved to automatically control.
Compare compared with prior art, the present invention can greatly increase master in the surface spraying organic short fiber layer of main transformer
The heat removal surface area of transformer, and the adsorbable substantial amounts of Mini-type water drop of hydrophily organic short fiber layer, when water droplet evaporates
Substantial amounts of heat can be taken away, in addition colourless or white organic short fiber layer can reflect more to sunlight, advantageously reduce heat
Absorption, made water fogging using the ultrasonic atomizing device of technology maturation, be more advantageous to being adsorbed onto with hydrophily organic short fiber
Layer, the moisture not absorbed can be flowed into Storage water tank, reduce the wasting of resources.
Embodiment
A kind of main transformer physical cooling method, it is characterised in that：In the surface of main transformer, especially radiating fin
Surface sprays one layer of hydrophily, ageing-resistant, colourless or white organic short fiber layer by electrostatic flocking technology；In main transformer
Lower section set Storage water tank, the fixed ultrasonic generator that can be made water fogging in side of the Storage water tank, it is described ultrasound occur
The water inlet pipe of device is extend into the Storage water tank, and the one or more fog floss hole of the ultrasonic generator is set
In the top of the main transformer, and the fog for discharging ultrasonic generator is shrouded on the surface of whole main transformer.In main transformer
The fixed temperature detect switch (TDS) in surface of depressor, when the surface degree of the main transformer is higher than the temperature set by the temperature detect switch (TDS)
During scope, the circuit turn-on powered to the ultrasonic generator is controlled, when the surface degree of the main transformer is less than the temperature control
When switching set temperature range, the circuit powered to the ultrasonic generator is controlled to end.It can so automatically control, reduce
Consumption.Further include a water supply installation being automatically replenished to the Storage water tank.It can be achieved to automatically control.
