Description
Technical field
The present invention relates to a kind of power equipment, particularly a kind of transformer breather of exempting from disassembling, assembling and replacing silica gel.
Background technology
The respirator of transformer has two functions: one is that the air in transformer body is communicated with outside air by respirator, and retainer body inner and outer air pressure is equal.When preventing hot weather or oepration at full load, transformer oil is because of swollen rising of heating up, and internal pressure raises to discharge and causes transformer oil spout.Two is absorb by the drier that respirator is in-built the moisture entered in transformer in air, the electric property making insulating oil in transformer keep good, prevents humid air from directly entering in installation for transformer, transformer oil is made moist, reduce or destroy the dielectric strength of transformer, so that winding.
At present, existing transformer breather generally comprises silica gel tank and is arranged at the lubricating cup below silica gel tank, and silica gel tank is built with silica gel, and lubricating cup is built with transformer oil.When silica gel variable color, show that silica gel makes moist, moisture pick-up properties reduces, and must change or drying.Existing transformer breather is in operation and changes in silica gel process and there is following problem:
1. change silica gel convenient not, majority needs whole respirator to remove operation, generally needs maintainer's operation;
2. silica gel tank mouth is comparatively large, time reinforced, need open top cover, when again loading onto after changing silica gel, easily occurs poor sealing phenomenon;
3. indivedual operating transformer breather, during due to eupnea, inside and outside lubricating cup has pressure reduction, and has bubble, therefore easily causes bottom silica gel immersion oil phenomenon;
4. change the silica gel general time at 15 ~ 30 minutes, now main transformer oil conservator air directly with extraneous UNICOM, easily cause internal wetted.
The domestic respirator also having exempted from from the disassembling, assembling and replacing silica gel of many manufacturer production, discharging opening designs in silica gel tank side by it, discharging opening design is unreasonable, discharging is obstructed, even part clout can not normally be laid down also needs again to remove whole for respirator, always consuming time longer, be generally subject to the criticism of user, so there is no further be promoted; Also have silica gel tank to adopt the transformer breather of eccentric design, its silica gel pot bottom makes the inclined-plane of certain slope, surface bottom discharging, but entirety unsightly, each module and the more difficult realization of unitary construction, respirator body also has the eccentric force of side direction for a long time, needs to take fixation.
Consider no matter which kind of form changes respirator silica gel, all need cleaning lubricating cup and more renew oil, the present invention have developed on this basis a kind of Novel free dismounting, can the transformer breather of quickly discharging material.
Summary of the invention
Main purpose of the present invention is the shortcoming overcoming prior art, there is provided one can realize exempting from dismounting, quickly discharging material, discharging is thoroughly unobstructed, replacing silica gel is easy and simple to handle, and the activity duration is short, and efficiency is high, and it is reinforced convenient, sealing is reliable, meanwhile, effectively can avoid the transformer breather of exempting from disassembling, assembling and replacing silica gel of bottom silica gel immersion oil phenomenon.
The present invention adopts following technical scheme:
Exempt from the transformer breather of disassembling, assembling and replacing silica gel, include silica gel tank, be arranged at the silica gel top ends of cans of silica gel tank upper end, the silica gel tank base being arranged at silica gel tank lower end and the lubricating cup be arranged at below silica gel tank, described silica gel pot bottom is formed with discharge port, silica gel tank bottom surface forms the low funneling Colony culture in Wai Gao center, described silica gel top ends of cans is provided with and the charge door be connected in silica gel tank, charge door is detachably provided with seal cover, described lubricating cup is threadedly connected to below silica gel tank base, described lubricating cup top cover is provided with the gas permeable barrier that can cover described discharge port, gas permeable barrier is formed with the air-vent being less than minimum colloidal silica.
Further, described seal cover is threaded with charge door, is provided with sealing ring in seal cover.
Further, described silica gel top ends of cans is formed by the outwards downward-sloping gradually curved surface in center.
Further, described lubricating cup is made up of interior lubricating cup and the outer lubricating cup be sheathed on outside interior lubricating cup, described interior lubricating cup lower ending opening, interior lubricating cup top cover is provided with the gas permeable barrier that can cover described discharge port, outer lubricating cup upper end open, inside and outside lubricating cup is all threaded connection below silica gel tank base, is formed with respiration channel between inside and outside lubricating cup and silica gel tank base.
Further, described interior lubricating cup adopts cast iron quality, and outer lubricating cup adopts glass material.
Further, described gas permeable barrier is a baffle plate being formed with the air-vent being less than minimum colloidal silica, or is made up of with the stainless (steel) wire being formed with the air-vent being less than minimum colloidal silica a baffle plate being formed with the air-vent being not less than minimum colloidal silica.
Further, described discharge port is arranged at silica gel tank bottom center, is made up of the dumping pit of multiple even setting.
From the above-mentioned description of this invention, compared with prior art, the present invention has following beneficial effect:
First, at silica gel pot bottom, discharge port is set, silica gel tank bottom surface forms the low funneling Colony culture in Wai Gao center, simultaneously, inside and outside lubricating cup is threaded connection below silica gel tank, interior lubricating cup top cover arranges the gas permeable barrier that discolour silica gel can be avoided to drop, after taking off lubricating cup, can automatic discharging under gravity, reasonable in design, can realize exempting from dismounting, quickly discharging material, discharging is thoroughly unobstructed, replacing silica gel is easy and simple to handle, activity duration is short, efficiency is high, main transformer oil conservator air and extraneous UNICOM overlong time can be avoided to cause internal wetted, generally do not have the operations staff of upkeep operation experience all can operate, the specific works being conducive to O&M one is carried out,
Second, silica gel top ends of cans arranges charge door, charge door detachably arranges seal cover, time reinforced, only seal cover need be opened, again load onto after changing silica gel, do not affect the sealing of respirator, simultaneously, silica gel top ends of cans is obliquely installed, feeding operation is convenient, and charge door meets the work angle of operating personnel more, also makes the charge door of small-sized respirator have larger space;
3rd, interior lubricating cup adopts cast iron quality, dismounting is more convenient, makes opening shape on the downside of interior lubricating cup, can conveniently clean, and by improving lubricating cup specification, suitably turn down the highest oil level, lubricating cup external diameter in increasing, increases the length of inside and outside lubricating cup, it is inner that the oil that can reduce in operation in lubricating cup enters silica gel tank, avoids bottom silica gel immersion oil phenomenon;
In a word, the present invention can realize exempting from dismounting, quickly discharging material, and discharging is thoroughly unobstructed, changes silica gel easy and simple to handle, activity duration is short, efficiency is high, and reinforced convenient, and sealing is reliable, simultaneously, effectively can avoid bottom silica gel immersion oil phenomenon, not have the operations staff of upkeep operation experience also can operate, the specific works being conducive to O&M one is carried out.
