Abstract
The invention discloses a quick replaceable oil storage cabinet moisture absorber device, which comprises a breathing pipe which is connected with an oil storage cabinet, wherein the breathing pipe is connected with a moisture absorber through a flange and a valve in sequence; a second passage which is communicated with the breathing pipe is arranged between the flange and the valve; and the valve is movably connected with the moisture absorber. On the premise of guaranteeing breathing capacity of the moisture absorber, the oil storage cabinet is guaranteed to be kept in a normal breathing state when breather silica gel is moisturized, and heavy gas production is not stopped, so that safe and reliable running of a transformer is guaranteed; by opening and closing a vacuum valve, the moisture absorber is put in or withdrawn through a tool-free cutting ferrule quick joint; one person can manually convey to replace the breather silica gel; and thus, the device is convenient and fast, a large amount of time and maintenance cost are saved, and the working efficiency is effectively increased.
Description
Technical field
The present invention relates to oil conservator dehydrating breather technical field in the transformer, relate in particular to a kind of oil conservator dehydrating breather device of fast changeable.
Background technology
In electric power system; Current domestic and international transformer oil conservator dehydrating breather is used and is not obtained paying attention to; It all is the working method of through type; These working methods do not have fine consideration various places conditions for equipment use, and just simple combination is communicated with transformer dehydrating breather with some rubber cushions with some screws, so go wrong easily.Short like the silica gel life cycle in the dehydrating breather, change silica gel with duration etc., influence power supply safety; Want 4 screws on the loose dehydrating breather in the past when changing silica gel, operate by 2 people and could accomplish this work.Because these screws all are ironworks with fixing base plate, rust is dead easily, and it is bigger to change difficulty; Cause silica gel to change complex process, sealing effectiveness control difficulty is particularly on average changed one less important 40 minutes; Cause the direct entry time of moisture longer, these have directly influenced the life cycle of silica gel.Main transformer, the main effect of standing with the transformer oil in the oil-filled equipments such as change, capacitor, main transformer tap changer are insulation, and moisture, impurity are the two big killers that influence the insulating oil insulation property.The main effect of respirator silica gel in oil-filled equipments such as main transformer, the change of standing, capacitor and main transformer tap changer is that absorption gets into the airborne moisture of these equipment conservators, impurity; Play very important filtration, slow down the degradation speed of insulating oil.But silica gel itself has also absorbed the moisture pulverize in the moisture red (below abbreviate as " variable color ") to it when filtering; So must change it after the silica gel variable color; With the good strainability of assurance silica gel, thus the insulation property of assurance insulating oil.Be defined in silica gel variable color amount 2/3 o'clock, must it be changed above silica gel handleless cup volume.The replacing time is longer, can bring more air to get in the transformer oil, influences the insulation property of transformer oil.Existing equipment is to cause the silica gel replacing time long, does not have the air through the dehydrating breather filtered through silica gel directly not get in the main transformer body, thereby makes the silica gel variable color of making moist, and this also is the technical barrier that the novel dehydrating breather device of development need solve.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, oil conservator dehydrating breather device of improving replacing speed, safe and reliable, economical and practical fast changeable.
A kind of oil conservator dehydrating breather device of fast changeable; Comprise the respiratory siphon that is connected with oil conservator; Said respiratory siphon is connected with dehydrating breather through flange, valve successively, and the second channel that setting is communicated with respiratory siphon between said flange and the valve flexibly connects between said valve and the dehydrating breather.
Said second channel comprises interconnective valve and dehydrating breather.
Between said valve and the dehydrating breather clamping mechanism is set.
It is unreasonable to the present invention is directed to existing respiration apparatus structure and seal form, is to cause the silica gel replacing time long, has adopted second channel.Main transformer is when operation, and respiration tracheae can not stop up, because the transformer temperature is not constant; The insulating oil oil level rose when temperature was high, and the air in the conservator is discharged through respirator, if seal respiration tracheae at this moment; Air in the conservator causes the Buchholz relay action because can not arrange; Have an accident, transformer also can be blasted when serious, and second channel is optimized to this respect exactly.In silica gel replacing process, remain the unimpeded of transformer respiration tracheae, and stopped the possibility of moisture access arrangement in replacing, kept the good strainability of silica gel.Fast changeable of the present invention oil conservator dehydrating breather device; The present invention is under the prerequisite of the respiratory capacity that guarantees dehydrating breather; When respirator silica gel makes moist; Guarantee that oil conservator can both be in the eupnea state in whole replacing process, the heavily protection of not stopping using, the safe and reliable operation of assurance transformer; Through the switching of vacuum valve, dehydrating breather is through exempting from instrument cutting ferrule quick union input or withdraw from, and a people can carry out the replacing of dehydrating breather silica gel by manual handling, and is convenient, fast, saved great amount of time and maintenance cost, effectively increases work efficiency.
Description of drawings
Below in conjunction with accompanying drawing the present invention is done further explanation:
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1; A kind of oil conservator dehydrating breather device of fast changeable; Comprise the respiratory siphon 2 that is connected with oil conservator 1, said respiratory siphon 2 is connected with dehydrating breather 61 through flange 3, valve 41 successively, the second channel that setting is communicated with respiratory siphon 2 between said flange 3 and the valve 41; Flexibly connect between said valve 41 and the dehydrating breather 61, said second channel comprises interconnective valve 42 and dehydrating breather 62.
Between said valve 41 and the dehydrating breather 61 clamping mechanism 51 is set.Between second channel valve 42 and the dehydrating breather 62 clamping mechanism 52 is set.When the silica gel of respirator 61 makes moist variable color need change the time, install to subsequent use small-sized dehydrating breather 62 on clamping mechanism 52 interfaces, open valve 42, at this moment dehydrating breather B brings into operation; Then close 41 valves, screw down dehydrating breather 61 from clamping mechanism 51 interfaces out of servicely, install to subsequent use large-scale dehydrating breather on clamping mechanism 51 interfaces; Open valve 41, this stylish dehydrating breather brings into operation, and valve-off 42 then; Screw down subsequent use small-sized dehydrating breather 62 out of service from clamping mechanism 52 interfaces. after implementing to transform, stop the chance in the moisture access arrangement body in changing the silica gel process, shortened the time of changing silica gel greatly; Whole process is 2 minutes, has improved the scarce efficient that disappears, after the enforcement new method; Stopped to have improved the reliability of power supply, changed before and after the dehydrating breather because of changing the phenomenon that silica gel stops heavily protection; Device center of gravity no change, the weight no change, normal operation has no effect to transformer.
