Description
Technical field
The invention belongs to technical field of power generation, more particularly to a kind of radiator of current transformer grid-connection cabinet.
Background technique
Wind-power electricity generation is a kind of clean renewable energy, the increasingly attention by countries in the world.Wind electric converter is
Wind-power electricity generation important component, including three grid-connection cabinet, control cabinet and power cabinet cabinet bodies, wherein grid-connection cabinet is for connection to send out
Electric system and network system, play the role of generator connecting in parallel with system.Grid-connected switch, grid-connected contact are mainly set in grid-connection cabinet cabinet body
The devices such as device, lightning protection power distribution assembly, fuse and confluence copper bar.Since electrical equipment is more in grid-connection cabinet, work as electrical equipment
When operating ambient temperature is higher than normal temperature, the parameter of electrical equipment will be changed, such as the action current of grid-connected switch
Parameter reduces, so that improper tripping occurs when the electric current flowed through is not up to desired action current and even explodes for grid-connected switch
The case where, it securely and reliably powers to wind-driven generator and causes adverse effect.
The radiator of existing grid-connection cabinet, major way are to be equipped with supply fan in cabinet body lower part, by sky cold outside cabinet body
Aspiration cabinet body top setting thermovent or adds extraction fan into cabinet, makes the intracorporal hot-air discharge of cabinet, to realize reduction
The purpose of cabinet body temperature.But component is different in grid-connection cabinet and electric parameter also has difference, this radiating mode holds
The heat dissipation dead angle of individual heater elements is easily caused, to cause the improper movement of grid-connected switch, influences the work effect of generator
Rate.
Summary of the invention
For the above technical problems, the present invention provides a kind of radiator of current transformer grid-connection cabinet.It, which radiates, imitates
Fruit is good, without heat dissipation dead angle.
The purpose of the present invention is achieved through the following technical solutions:
A kind of radiator of current transformer grid-connection cabinet of the present invention, including installing radiator fan and thermovent on cabinet body,
In two radiator fans be mounted on cabinet door lower part, symmetrical, other two radiator fan is separately mounted to side cabinet top
At cabinet door face confluence copper bar；Being mounted on the radiator fan in cabinet door lower part and cabinet door at face confluence copper bar is supply fan,
The radiator fan being mounted on side cabinet is exhaust fan, is set respectively in the cabinet body back plate of cabinet door top and corresponding confluence copper bar
Set thermovent I and thermovent II.
Further, filter screen is provided on the thermovent I and thermovent II.
The invention has the benefit that
1. good heat dissipation effect of the present invention, without heat dissipation dead angle.The radiator fan wind direction of its cabinet door lower part two inwardly, by external rings
Outwardly, the intracorporal hot-air of cabinet is discharged for the cold air inspiration cabinet body in border, the radiator fan wind direction of side cabinet topmost.
2. the present invention is while reducing bulk temperature in cabinet body, directly right by the way that radiator fan is arranged at confluence copper bar
Copper bar cools down, and eliminates the heat dissipation dead angle of main heater element in cabinet body, improves heat dissipation effect, reduce grid-connection cabinet and open
The number of stoppages is closed, generating efficiency is improved.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
In figure: 1. electrical cabinets, 2. supply fans, 3. air inlets, 4. exhaust fans, 5. exhaust outlets, 6. thermovents I, 7. thermovents
Ⅱ。
Specific embodiment
Below by embodiment and attached drawing, the invention will be further described.
Embodiment: the present invention includes the radiator fan and thermovent 6 being mounted on 1 cabinet body of electrical cabinet, two of them heat dissipation
Fan is mounted on cabinet door lower part, symmetrical, other two radiator fan is separately mounted to side cabinet top and cabinet door face
At confluence copper bar；Being mounted on the radiator fan in cabinet door lower part and cabinet door at face confluence copper bar is supply fan 2, wind direction court
Interior, by the cold air inspiration cabinet body of external environment, being mounted on radiator fan on side cabinet is exhaust fan 4, wind direction outwardly,
By the intracorporal hot-air discharge of cabinet；Divide at the upper angle that supply fan is not opened on cabinet door top and in the cabinet body back plate of corresponding confluence copper bar
It She Zhi not thermovent I 6 and thermovent II 7.
Filter screen is provided on the thermovent I 6 and thermovent II 7.
The present invention in grid-connection cabinet, interior main components include grid-connected contactor, grid-connected switch, lightning-protection module group,
Fuse, confluence copper bar, the copper bar being connected to motor and current transformer connecting copper bar and grounding copper bar and soft copper bar etc., wherein
Confluence copper bar connects grid-connected contactor and grid-connected switch, is the highest component of cabinet body temperature, and directly affect grid-connected open
Close one of element.
The course of work of the invention are as follows: the supply fan 2 of cabinet body lower part aspirates the cold air in environment into cabinet body, cold air
The heat that heater element generates is absorbed when heater element intracorporal by cabinet and becomes hot-air, and hot-air rises, on side cabinet
Thermovent 6 on the exhaust fan 4 and cabinet door in portion discharges high-temperature gas；Meanwhile it is straight to be mounted on the supply fan 2 at confluence copper bar
It connects and blows to confluence copper bar, and thermovent II 7 corresponding with radiator fan is set at confluence copper bar rear, confluence copper bar is worked and is produced
Raw heat discharges rapidly.Since confluence copper bar is different, quantity of heat production is high and is not easy to be blown to by ventilating air, close to remittance
Especially increase ventilation device at stream copper bar, it is ensured that these different elements are arrived by wind, to eliminate grid-connection cabinet
Heat dissipation dead angle, improves heat dissipation effect.
