Detailed description of the invention
Below with reference to Figure of description and specific embodiment, this utility model is described in further details.
As shown in Figures 2 and 3, the station of the present embodiment is with becoming switch cubicle heat dissipation wind channel system, including intake air way 4 and be located at
Breeze fan 5 in intake air way 4, intake air way 4 is provided with the first air delivery duct 41 and second toward 1 liang of Lateral supply of transformator respectively and send
Air channel 42, it is simple that this station becomes switch cubicle heat dissipation wind channel system structure, it is ensured that the supply of transformator 1 both sides cooling blower 3, from
And make high and low pressure coil cooling effect basically identical, and the beneficially safe operation of transformator 1, improve the use of transformator 1
Life-span.
First air delivery duct 41 is positioned at side, cable vault 2 and the outlet cooling blower 3 towards transformator 1 side, the second air-supply
Road 42 is positioned at the bottom of cable vault 2 and extends to below the cooling blower 3 of transformator 1 opposite side.In the present embodiment, the first air-supply
Road 41 structure is essentially identical with existing heat dissipation wind channel, and is arranged at cable vault 2 right-side outlet towards the cooling wind on the right side of transformator 1
Machine 3, correspondingly, the second air delivery duct 42 extends to below the cooling blower 3 on the left of transformator 1.
In the present embodiment, the list that the gas being provided with in intake air way 4 in preventing cable vault 2 is reversely discharged through intake air way 4
To valve member 6, one-way cock assembly 6 is located between breeze fan 5 and cable vault 2, when there is arc fault in switch cubicle, interior
When portion's pressure is excessive, the available one-way cock assembly 6 being located in intake air way 4 prevents gases at high pressure from reversely discharging through intake air way 4,
Gases at high pressure are avoided to jeopardize the safety of operator.
In the present embodiment, stand and also include microswitch 7, microswitch 7 and air-supply wind by change switch cubicle heat dissipation wind channel system
The power supply of machine 5 couples, when one-way cock assembly 6 is closed, and microswitch 7 action, the power supply excision of breeze fan 5, make air-supply
Blower fan 5 quits work, and prevents breeze fan 5 from damaging.
In the present embodiment, one-way cock assembly 6 includes valve plate 61, valve plate installed part 62 and valve plate keeper 63, valve plate
Installed part 62 is located at the air outlet 51 of breeze fan 5, and microswitch 7 is installed on valve plate installed part 62, valve plate installed part 62
On offer air vent 621, valve plate 61 top is hinged with valve plate installed part 62, valve plate 61 bottom support be located at valve plate keeper 63
On, have between valve plate 61 and air vent 621 between the gap that supplied gas flows through, namely valve plate 61 and valve plate installed part 62 and have
Angle so that one-way cock assembly 6 is in open mode.
In the present embodiment, valve plate keeper 63 is elastic component, valve plate keeper 63 be shaped as U-shaped and opening towards valve plate
Installed part 62 is arranged, and the top being located at valve plate keeper 63 is supported in valve plate 61 bottom.
The operation principle that station of the present utility model becomes switch cubicle heat dissipation wind channel system is as follows:
As shown by the arrows in Figure 2, during normal ventilation and heat, cold air is sequentially passed through the air intake of intake air way 4 by breeze fan 5
Mouthfuls 43, gap between valve plate 61 and air vent 621 and the first air delivery duct 41 and the second air delivery duct 42 are supplied respectively to transformation
The cooling blower 3 of device 1 left and right sides, it is achieved air blast cooling, switch cubicle normally works；When arc fault occurs in switch cubicle,
Internal pressure is increased dramatically, and gases at high pressure enter in intake air way 4 through the first air delivery duct 41 and the second air delivery duct 42, promotes valve plate 61
Rotating up to cover the air vent 621 on valve plate installed part 62, elastic valve plate keeper 63 top relies on natural resiliency
Move, valve plate 61 is locked, thus prevents internal high-pressure gas to leak from air inlet 43, protect the peace of operations staff effectively
Entirely, after valve plate 61 is closed, microswitch 7 also action simultaneously, the working power of excision breeze fan 5, breeze fan 5 stops work
Make, prevent breeze fan 5 from damaging；After troubleshooting, recover valve plate 61 to initial position manually, utilize elastic valve
Plate keeper 63 keeps valve plate 61 to be in poised state, it is to avoid rotate to air vent 621, affects the normal air-supply of breeze fan 5.
