In the exhaust apparatus that the utility model provides, it is before work, liquid outlet with liquid-transport pipe-line seals earlier, liquid is entered wherein from the inlet of liquid-transport pipe-line, and when liquid entered into liquid-transport pipe-line, liquid can be extruded liquid-transport pipe-line by discharge duct with the air in the liquid-transport pipe-line, after liquid is extruded the air in the liquid-transport pipe-line fully, open the liquid outlet of liquid-transport pipe-line, liquid flows out from liquid outlet, thereby realizes the exhaust purpose.
When the exhaust apparatus that provides when the utility model is used for vacuum filter and injects insulating oil to power transformer, the inlet of liquid-transport pipe-line is connected with vacuum filter, the liquid outlet of liquid-transport pipe-line is connected with the pouring orifice of power transformer, before opening vacuum filter, pouring orifice with power transformer seals earlier, after vacuum filter is opened, be present in the vacuum filter body and oil pipe in air under the extruding of insulating oil, enter into liquid-transport pipe-line, after insulating oil enters liquid-transport pipe-line, air is insulated oil to be squeezed to discharge duct, in liquid-transport pipe-line, be full of insulating oil, air is got rid of fully, the pouring orifice of turns on power transformer then, and insulating oil enters into the inner chamber of power transformer.
The exhaust apparatus that the utility model provides, when being used for vacuum filter to power transformer injection insulating oil, its can be present in the vacuum filter body and oil pipe in air discharge by discharge duct, avoid air to enter into the vacuum lumen of power transformer with insulating oil, power transformer can not insulate and make moist, and has improved the oiling quality significantly.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
The structural representation of the exhaust apparatus that Fig. 1 provides for the utility model embodiment.
Among Fig. 1:
Liquid-transport pipe-line 1, discharge duct 2, inlet 3, liquid outlet 4, valve 5, adpting flange 6.
Embodiment
The utility model provides a kind of exhaust apparatus, has avoided vacuum oil-filter the space to be injected the inner chamber of power transformer when oiling in power transformer.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the exhaust apparatus that the utility model embodiment provides, it comprises:
Liquid-transport pipe-line 1 with inlet 3 and liquid outlet 4;
Discharge duct 2 with liquid-transport pipe-line 1 conducting.
In the exhaust apparatus that present embodiment provides, it is before work, liquid outlet 4 with liquid-transport pipe-line 1 seals earlier, liquid is entered wherein from the inlet 3 of liquid-transport pipe-line 1, and when liquid entered into liquid-transport pipe-line 1, liquid can be extruded liquid-transport pipe-line 1 by discharge duct 2 with the air in the liquid-transport pipe-line 1, after liquid is extruded the air in the liquid-transport pipe-line 1 fully, open the liquid outlet 4 of liquid-transport pipe-line 1, liquid flows out from liquid outlet 4, thereby realizes the exhaust purpose.
When the exhaust apparatus that provides when present embodiment is used for vacuum filter and injects insulating oil to power transformer, the inlet 3 of liquid-transport pipe-line 1 is connected with vacuum filter, the liquid outlet 4 of liquid-transport pipe-line 1 is connected with the pouring orifice of power transformer, before opening vacuum filter, pouring orifice with power transformer seals earlier, after vacuum filter is opened, be present in the vacuum filter body and oil pipe in air under the extruding of insulating oil, enter into liquid-transport pipe-line 1, after insulating oil enters liquid-transport pipe-line 1, air is insulated oil to be squeezed to discharge duct 2, in liquid-transport pipe-line 1, be full of insulating oil, air is got rid of fully, the pouring orifice of turns on power transformer then, and insulating oil enters into the inner chamber of power transformer.
