Referring to Fig. 1 and Fig. 2, a kind of cooling system of roof current transformer has the cabinet 1 of chamber including inside, cabinet 1
Side and bottom are each formed with the first air duct 2, and the side of cabinet 1 is fixedly installed main air blower 3, and the side of cabinet 1 offers out
The both ends in air port 4, the first air duct 2 are connected to main air blower 3 and air outlet 4 respectively, and main air blower 3 is electrically connected with can be to main air blower 3
First power supply of power supply, the inside of 1 chamber of cabinet are fixedly installed multiple power modules 5, and power module 5 is fixedly connected with heat dissipation
Plate base 6, heat spreader substrate 6 have multiple cooling fins 7, and one end of cooling fin 7 connect with power module 5, cooling fin 7 it is another
End is located at the inside in the first air duct 2, to radiate to power module 5;Multiple power modules 5 are located at the middle part of 1 chamber of cabinet, multiple
The second air duct 8 is formed between power module 5 and the inner sidewall of cabinet 1, the inside in the second air duct 8 is fixedly installed centrifugal blower
9, so that the air circulation in the second air duct 8 circulates, thus the stream of 1 chamber interior air of cabinet, and then avoid because of local mistake
Heat and scaling loss power module 5 etc. devices, centrifugal blower 9 are electrically connected with the second source that can be powered to centrifugal blower 9, second is electric
The voltage in source is different from the voltage of the first power supply, such as the first power supply is 380V, second source 110V, so that centrifugal blower
9 use the power supply mode different from main air blower 3, thereby may be ensured that the case where main air blower is due to 380V power supply system failure
Under, being set to the centrifugal blower 9 inside the second air duct 8 still can be used, and then ensure that power module 5 is run reliable
Property.
Based on above-mentioned, the cooling system of the utility model roof current transformer passes through setting the first air duct 2, main air blower 3, second
Air duct 8 and centrifugal blower 9 realize two kinds of circulation patterns of outer circulation and interior circulation and radiate to power module 5, wherein outside
Under circulation pattern, cold air is carried out under the drive of main air blower 3 by the first air duct 2 and to the cooling fin 7 in the first air duct 2
Heat exchange is then recycled by the output of air outlet 4 to the outside of cabinet 1 to provide main heat dissipation for power module 5 inside
Under mode, air is logical in 8 inner recirculation flow of the second air duct under the drive of centrifugal blower 9, to realize the equal of 1 inner air of cabinet
Stream, so that heat is evenly distributed, while when main air blower 3 breaks down, can guarantee the normal use of crucial heating device,
Therefore, the cooling system of the utility model roof current transformer is without increasing the air channel structure with redundancy radiating mode, without setting
It is set to the blower of redundancy air duct air feed, and set centrifugal blower 9 only takes up the space of 1 chamber interior of cabinet, thus phase
For traditional roof current transformer cooling system, the size of structure is significantly reduced, and does not destroy the integrated of current transformer itself
Degree, at the same time, improves the reliability of 5 radiation processes of power module, and then ensure that power module 5 continues normally to transport
Row.
As a preference, centrifugal blower 9 is arranged towards power module 5.
In order to further increase radiating efficiency, as depicted in figs. 1 and 2, wind scooper 10, wind-guiding are fixedly installed on cabinet 1
Cover 10 is set at air outlet 4 (in the current transformer grid being specifically as follows at air outlet 4), to the wind flowed out from air outlet 4
Water conservancy diversion is carried out, wind scooper 10 cuts oblique setting from cabinet 1 upwards, so that the top of the wind direction air outlet 4 flowed out from air outlet 4 is flowed
It is dynamic, to guarantee that hot-air gathers upwards, and then further improve radiating efficiency.
Cooling fin 7 is placed in top surface under traditional roof current transformer radiating mode, however cooling fin 7 is placed in upper surface faces and stepped on
The risk stepped on, heat dissipation effect decline is obvious in the short time, and furthermore cooling fin 7 is placed in upper surface and faces solar radiation, heat dissipation effect
Equally have a greatly reduced quality.Based on this, as depicted in figs. 1 and 2, multiple cooling fins 7 are preferably fixedly installed on the inner sidewall of cabinet 1
Upper or cabinet 1 bottom, so that heat dissipation effect is guaranteed.
Preferably, multiple cooling fins 7 are arranged along the vertical direction, hot-air is conducive to this and is flowed up.

One step guarantees 5 reliability of operation of power module.
In addition, cabinet 1 is surrounded by multiple aluminium alloy plates by riveting, to mitigate weight and thermal deformation.
In addition, the doorframe at 1 top of cabinet uses water-blocking groove, while sealing strip is also configured on the door-plate of cabinet 1, it is therefore, whole
A cabinet 1 uses double-layer sealing structure, and waterproof effect is more preferable.
In order to better understand the above embodiments of the present invention, as shown in Fig. 2, the utility model roof current transformer
The radiation processes of cooling system are as follows:
Under outer circulation mode, when main air blower 3 works normally, the cold air outside current transformer is pooled to the first air duct 2, the
The hot wind that the inside in one air duct 2 is formed after exchanging heat to cooling fin 7 is blown to outside car body by the air outlet 4 of cabinet 1;
Under interior circulation pattern, air is logical in 8 inner recirculation flow of the second air duct under the drive of centrifugal blower 9, to realize case
The stream of 1 inner air of body, so that heat is evenly distributed, when main air blower 3 breaks down, centrifugal blower 9 is still operated normally,
To guarantee the normal operation of crucial heating device.
