But, how to optimize the scheme of the electric equipment chamber Design of ventilation such as capacitor and ground connection change further, adapting to the renewal of substation facilities layout and equipment operation attended mode, ensure the safety of electrical network, stable operation, is a very necessary job with having realistic meaning.
The capacitor chamber in manned substation and the Design of ventilation of ground connection change room in the past, as shown in Figure 1, many employings natural air inlet mechanical exhaust mode, the body of wall bottom, side that capacitor chamber and ground connection become room 1 is provided with shutter air inlet 2, the top of opposite side body of wall is provided with exhaust outlet 3, is provided with blower fan 4 in exhaust outlet 3.The mode that this positive mechanical is ventilated, by the fixed cycle operator of operator on duty, can improve the running environment of capacitor, ground connection change room.At present, the capacitor chamber of unattended substation and ground connection become the Design of ventilation of room, all adopt above-mentioned draft type, the shortcoming of this draft type is: one is the ventilation by forced draft that can not utilize room air, two is because electric substation is unattended, makes capacitor, ground connection becomes that the running environment of room is more difficult to improve at any time, if things go on like this, the little life-span to affecting the electrical equipment such as capacitor, ground connection change, greatly to the safe operation jeopardizing electric substation.
Utility model content
The applicant, for the above-mentioned shortcoming of prior art, carries out studying and improving, and provide a kind of electric substation capacitor chamber and ground connection to become chamber ventilated structure, it has good, the safe and reliable feature of ventilation effect.
In order to solve the problem, the utility model adopts following scheme:
A kind of electric substation's capacitor chamber and ground connection become chamber ventilated structure, comprise capacitor chamber and ground connection change room, the body of wall bottom, side that capacitor chamber and ground connection become room is provided with the first shutter air inlet, its opposite side body of wall top is provided with mechanical exhaust mouth, blower fan is provided with in mechanical exhaust mouth, the body of wall top being positioned at the first shutter air inlet side is provided with the second shutter air inlet, and the inner side of the second shutter air inlet is provided with ventilation valve; The body of wall top being positioned at mechanical exhaust mouth side is provided with shutter air outlet, and shutter air outlet is positioned at the top of mechanical exhaust mouth and with the second shutter air inlet in sustained height, the inner side of shutter air outlet is provided with fire resisting damper; Also be provided with intelligent controller in described capacitor chamber and ground connection change room, intelligent controller comprises microcontroller, timing controller and temperature sensor, and microcontroller is connected with ventilation valve, fire resisting damper and blower fan.
Technique effect of the present utility model is:
The utility model has fully taken into account the indoor layout of converting equipment and unwatched feature, has both taken full advantage of the free convection of room air, turn avoid short-circuit of air when blower fan is opened.The running environment of unattended Indoor Substations capacitor chamber and ground connection change room can be improved significantly, extend the service life of the electrical equipment such as capacitor, ground connection change, improve the reliability of safe running of transformer substation.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
As shown in Figure 2 and Figure 3, electric substation's capacitor chamber of the present embodiment and ground connection become chamber ventilated structure, comprise capacitor chamber and ground connection change room 1, the body of wall bottom, side that capacitor chamber and ground connection become room 1 is provided with the first shutter air inlet 2, its opposite side body of wall top is provided with mechanical exhaust mouth 3, be provided with blower fan 4 in mechanical exhaust mouth 3, the inner side that the body of wall top being positioned at the first shutter air inlet 2 side is provided with the second shutter air inlet 7, second shutter air inlet 7 is provided with ventilation valve 8; The body of wall top being positioned at mechanical exhaust mouth 3 side is provided with shutter air outlet 5, and shutter air outlet 5 is positioned at the top of mechanical exhaust mouth 3 and is in sustained height with the second shutter air inlet 7, and the inner side of shutter air outlet 5 is provided with fire resisting damper 6.
As shown in Figure 2 and Figure 3, be also provided with intelligent controller 9 in capacitor chamber and ground connection change room 1, intelligent controller 9 comprises microcontroller 91, timing controller 92 and temperature sensor 93, and microcontroller 91 is electrically connected with ventilation valve 8, fire resisting damper 6 and blower fan 4.Wherein, timing controller 92, for setting-up time, realizes timing to the startup of blower fan 4, ventilation valve 8 and fire resisting damper 6 and closedown; Be built-in with two kinds of threshold temperature in temperature sensor 93, be respectively high temperature threshold values and middle temperature threshold values, when reaching middle temperature threshold values, starting blower fan 4 by microcontroller 91 and closing fire resisting damper 6 (fire resisting damper 6 also can be closed automatically); When reach a high temperature threshold values time, by microcontroller 91 start blower fan 4 and simultaneously start ventilation valve 8.
