Compared with prior art, the utility model has the advantage of: this load switch of transformer online refueling device structure is simple, volume is little, simple, convenient, practical, only need open or close the online oiling that corresponding valve can realize load switch of transformer, and in refueling process, connect each part without the need to disassembling or installing, the quantity of energy consumed is little, and operating efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of load switch of transformer refueling device in prior art.
Fig. 2 is the structural representation of the online refueling device of load switch of transformer in the utility model embodiment one.
Fig. 3 is the structured flowchart of the online refueling device of load switch of transformer in the utility model embodiment two.
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figure 1, the tool part of loaded switch of the prior art needs to be immersed in loaded switch grease chamber 8, loaded switch grease chamber 8 is connected with a flowline 81, flowline 81 is connected with sample valve 82, when needs gather oil sample, open sample valve 82 and gather oil sample.Loaded switch grease chamber 8 also connects a loaded switch oil conservator 2 by a Buchholz relay 9, loaded switch oil conservator 2 connects a dehydrating breather 4 by moisture absorption pipeline 41, also being provided with one in loaded switch oil conservator 2 for monitoring the oil level indicator 21 of oil level, after oil level declines, then sending low oil level and reporting to the police.Now then need transformer to have a power failure, remove the cover plate screw at loaded switch oil conservator 2 top, open cover plate, then manually utilize fueling vehicle to refuel, think judgement volume read-out according to the instruction of oil level indicator 21.After oiling completes, build cover plate, install cover plate fixed screw, finally again by transformer transmission operation.The whole operating process time is longer, and workload is large.
Embodiment one
As shown in Figure 2, the online refueling device of load switch of transformer in the present embodiment, comprise gasoline pump 1, be communicated in the inflow pipeline 3 between gasoline pump 1 and loaded switch oil conservator 2, be connected to the three-way pipe 42 on moisture absorption pipeline 41 and be connected to the breather pipe 5 of three-way pipe 42 openend.
Wherein, inflow pipeline 3 is provided with an inlet valve 31, breather pipe 5 is provided with an air outlet valve 51, between three-way pipe 42 and dehydrating breather 4, be provided with a break valve 6.
The online refueling device of this load switch of transformer in use, when oil level indicator 21 detects that the oil level of current loaded switch oil conservator 2 drops to after lower than the threshold value preset, send low oil level to report to the police, operating personnel open air outlet valve 51, loaded switch oil conservator 2 is communicated with ambient atmosphere, thus make loaded switch oil conservator 2 and ambient atmosphere air pressure keep balancing, to facilitate oil-feed.Operate break valve 6 simultaneously, make break valve 6 keep closed condition, block being communicated with of dehydrating breather 4 and loaded switch oil conservator 2.Then start gasoline pump 1, open inlet valve 31 simultaneously, gasoline pump 1 injects oil by inflow pipeline 3 in loaded switch oil conservator 2.In this process, due to loaded switch oil conservator 2 and ambient atmosphere air pressure balance, be exhausted without the need to setting up exhaust apparatus, refueling process is very smooth and easy.After the oil level of oil level indicator 21 instruction meets the demands, close gasoline pump 1, close the inlet valve 31 on inflow pipeline 3 simultaneously.Operate break valve 6 afterwards, make break valve 6 stay open state, close air outlet valve 51 simultaneously.Dehydrating breather 4 like this by the water vapor absorption in oil, thus can play the effect of protection loaded switch.Aforesaid refueling process is simple, convenient, practical, and refueling process energy consumption is low, efficiency of refueling is high.
Embodiment two
As shown in Figure 3, the difference of the present embodiment and embodiment one is only: the online refueling device of the load switch of transformer in the present embodiment also comprises a controller 7, the signal input part of controller 7 is connected with the oil level indicator 21 in loaded switch oil conservator 2, and the signal output part of controller 7 is connected with gasoline pump 1, inlet valve 31, air outlet valve 51, break valve 6 respectively.The calculating of controller 7 pairs of oil level indicator 21 image data and adopt control algolithm of the prior art according to the method for data to the control action of gasoline pump 1, inlet valve 31, air outlet valve 51, break valve 6 that oil level indicator 21 gathers.
And refueling operation artificial in embodiment one, all utilize controller 7 to carry out automatic control action.Namely when oil level indicator 21 gather data lower than preset threshold value after, controller 7 according to setting operating sequence control open air outlet valve 51, close break valve 6, start gasoline pump 1, open inlet valve 31.Under control of the controller 7 gasoline pump 1 is controlled accurately, realize refueling process.The data gathered when oil level indicator 21 to meet in loaded switch oil conservator 2 after oil mass requires, controller 7 controls to cut out gasoline pump 1 according to the operating sequence of setting, cut out inlet valve 31, opens break valve 6, cuts out air outlet valve 51.
The above process implementation automatic on-line refueling process of load switch of transformer, whole refueling process precisely, simple, efficient.
