The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As Fig. 1-shown in Figure 5, described transformer station sulfur hexafluoride supercharging air interchanger comprises air inlet 1, toxin expelling fan 2, sulfur hexafluoride sealed combination electrical equipment 3, sulfur hexafluoride sensor 4, substation intelligent guarantee case 5, filter bag 5-1, control cabinet 5-2, frequency conversion fan 5-3, silencer 5-4, evaporimeter 5-5, air-conditioning draught fan 5-6, air conditioner filter screen 5-7, guidance panel 5-8, clean wind air outlet 5-9, air-conditioning air inlet 5-10, air-conditioner air outlet 5-11, steel wire 5-12, shows control flow 6 etc.
As Fig. 2～shown in Figure 5, the utility model transformer station sulfur hexafluoride supercharging air interchanger, comprise the substation intelligent guarantee case 5 that is placed in transformer station, described substation intelligent guarantee case 5 inside are divided into three of left, center, right cavity, filter bag 5-1 is installed in left cavity, lay control cabinet 5-2, frequency conversion fan 5-3, silencer 5-4 in middle cavity from top to bottom, evaporimeter 5-5, air-conditioning draught fan 5-6, air conditioner filter screen 5-7 are installed in right cavity from top to bottom successively; Described middle cavity front is provided with display screen and guidance panel 5-8, clean wind air outlet 5-9, described right cavity front is provided with air-conditioning air inlet 5-10 and air-conditioner air outlet 5-11, the described left cavity back side is steel wire 5-12, sees through steel wire 5-12 and is communicated with outside transformer substation; The frequency conversion fan 5-3 outlet of control cabinet 5-2 below is connected with silencer 5-4; It is characterized in that: the sulfur hexafluoride sensor 4 that is connected with control cabinet 5-2 is set in transformer station, on sidewall of transformer station, air inlet 1 and toxin expelling fan 2 are set, intelligent substation environment-guarantee case 5 is set on another sidewall of transformer station, demonstration control flow 6 is set on transformer station's inlet/outlet abutment wall wall, and described air inlet 1, toxin expelling fan 2, demonstration control flow 6 all are connected with control cabinet 5-2 by wire.
Described air inlet 1 is arranged on close end face place, transformer station's sidewall upper end.
Described toxin expelling fan 2 is arranged on place, close ground, transformer station's sidewall lower end, so that proportion is about the discharging of the sulfur hexafluoride gas of 5.1 times of air.
Described sulfur hexafluoride sensor 4 is arranged near place, ground, sulfur hexafluoride sealed combination electrical equipment 3 bottoms in transformer station, and when the sulfur hexafluorides leakage occured sulfur hexafluoride sealed combination electrical equipment 3, sulfur hexafluoride sensor 4 can detect in the very first time.
The utility model course of work is as follows: when sulfur hexafluoride sensor 4 monitors that in transformer station, the concentration of sulfur hexafluoride value rises to the higher limit of setting, intelligent substation environment-guarantee case 5 sends instruction, 2 startups of toxin expelling fan, air inlet 1 are opened, this moment, indoor a large amount of sulfur hexafluoride gas drained into outdoorly from sidewall bottom by toxin expelling fan 2, and simultaneously outdoor a large amount of new air enter indoor from top side wall air inlet 1.Sulfur hexafluoride gas density is more much bigger than air, and proportion is about 5.1 times of air, and therefore, in air, sulfur hexafluoride gas sinks naturally, and in transformer station's lower space, sulfur hexafluoride gas concentration is high.So toxin expelling fan 2 is arranged on bottom sidewall, air inlet 1 is arranged on top side wall.Increase the content of indoor oxygen by this process, discharged room sulfur hexafluoride gas.Until the room sulfur hexafluoride concentration value is when dropping to preset lower limit, intelligent substation environment-guarantee case 5 send instruction make toxin expelling fan 2 out of service, close air inlet 1 simultaneously.This moment, room sulfur hexafluoride concentration was in safe range.Enter into transformer station as personnel indoor, just can not suffocate because of anoxic.
If the room sulfur hexafluoride concentration value rises to the capping value, and the toxin expelling fan is after 2 operation a period of times, sulfur hexafluoride sensor 4 collects room sulfur hexafluoride concentration when also continuing to rise, intelligent substation environment-guarantee case 5 opens automatically, the discharge of sulfur hexafluoride gas in accelerating chamber strengthens the ability of oxygenation ventilation.Until the room sulfur hexafluoride concentration value is when dropping to preset lower limit, intelligent substation environment-guarantee case 5 and toxin expelling fan 2 are just automatically out of service.
The utility model is provided with control cabinet, sulfur hexafluoride sensor, toxin expelling fan etc. by installing in transformer station, can realize the monitoring of sulfur hexafluoride gas concentration in transformer station and regulate, the demonstration control flow of installing on transformer station's exterior wall simultaneously can show constantly the room sulfur hexafluoride concentration value, and can start the toxin expelling fan by direct control.Need not manual intervention, it has installs simply, easy to use, and the energy-saving and environmental protection product that moves under low energy consumption state is simple to operate.
