Abstract
The invention relates to a transformer rebreather structure which comprises a breather tank filled with drying agents. A breather tube connected with an oil line in a transformer via a pipeline is arranged in the breather tank and penetrates through the breather tank. The transformer rebreather structure is characterized in that the breather tube comprises an air guide section located in the breather tank and a free section located outside the breather tank, a one-way air valve is arranged in the free section of the breather tube, the air guide section of the breather tube comprises an upper air guide tube located on the upper side of the breather tank and a lower air guide tube located on the lower side of the breather tank, the upper air guide tube and the lower air guide tube are in sealed connection, a plurality of air guide holes are formed in the walls of the upper air guide tube and the lower air guide tube, a vent hole is formed in the bottom of the breather tank, and a rubber sealing cover is connected with the bottom of the breather tank via a reset spring. By means of the transformer rebreather structure, an oil cup structure is omitted, product operating performance is not affected during equipment transportation and installation, and normal operation is guaranteed.
Description
Technical field
The present invention relates to a kind of transformer breather structure, meet the needs of the transformer course of work.
Background technology
Transformer breather is also moisture absorber of transformer, or transformer silica gel tank, transformer dry agent, it act as and in absorbed air, enters the moisture in conservator poly-bag, barrier film, remove and be dried airborne foreign material and the moisture that enters transformer (or instrument transformer) oil conservator due to the variation of temperature of oil in transformer, in order to avoid transformer makes moist, to guarantee the dielectric strength of transformer oil.When transformer expanded by heating, the air that exhalation transformer is inner unnecessary; When temperature of oil in transformer reduces contraction, suck extraneous air.When sucking extraneous air, the transformer oil in oil storage box filters extraneous air, and then silica gel will not have the moisture content of elimination to absorb, and makes transformer oil in transformer not be subject to the intrusion of moisture content in extraneous air, makes its water content all the time in standard.The transformer oil holding in transformer lubricating cup plays isolated air effect, the cloche of a bottom of which has holes is installed in lubricating cup inboard by an axle center bolt in respirator bottom, when ambient temperature reduces, oil drives capsule to shrink, oil in transformer lubricating cup is drawn onto in inboard cloche, oil level declines, when in lubricating cup, pasta and cloche bottom oil level maintain an equal level, as transformer oil further shrinks, to cause lubricating cup inner oil seal face destroyed, air enters capsule by silica gel tank, and Here it is transformer capsule is air-breathing; When exhaling, air is by pressure-acting, and the oil pressure in lubricating cup inner glass cover is fallen and fair position, cloche bottom, between lubricating cup and cloche, oil level raises, slightly large to pressure, and air is by destroyed fluid side, be discharged to outside silica gel tank, transformer is being exhaled.But the structure of existing respirator all adopts cup structure of extraction described above, but the oil body of storing can make lubricating cup in installation and transportation in leaks, thereby has influence on the follow-up use of product.
Summary of the invention
In view of the deficiencies in the prior art, the object of the present invention is to provide a kind of transformer breather structure.
Technical program of the present invention lies in:
A kind of transformer breather structure, comprise the breather tank that is equiped with drier, in described breather tank, be installed on the respiratory siphon being connected with transformer internal oil passages pipeline, described respiratory siphon runs through breather tank, it is characterized in that: described respiratory siphon comprises and is positioned at the air-guide section of breather tank and is positioned at the free segment outside breather tank, the respiratory siphon that is positioned at free segment is provided with a Non-return air valve, the respiratory siphon that is positioned at air-guide section comprises the upper wireway that is positioned at breather tank upside and the downtake that is positioned at breather tank downside, between described upper wireway and downtake, be tightly connected, and offer some gas ports on the tube wall of described upper wireway and downtake, the bottom of described breather tank offers air vent hole, and the bottom of described breather tank is connected with rubber closure through back-moving spring.
Wherein, in described breather tank, be also provided with a circle in order to the electric heating assembly of bake drying agent.
Between described respiratory siphon and breather tank, by heat-resistant pressure-resistant sealing ring, seal.
The bottom of described breather tank is outer lug boss structure, and air vent hole is positioned in outer lug boss, and the relative air vent hole of described rubber closure place is provided with sealing protuberance, and described rubber closure seals air vent hole when reset condition.
The invention has the advantages that: the present invention saves cup structure of extraction, make equipment also can not affect product work performance in transportation and in installing, ensure normal operation.
Accompanying drawing explanation
Fig. 1 embodiment of the present invention structural representation.
Embodiment
For above-mentioned feature and advantage of the present invention can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
With reference to figure 1, the present invention relates to a kind of transformer breather structure, comprise the breather tank 1 that is equiped with drier 2, in described breather tank 1, be installed on the respiratory siphon 3 being connected with transformer internal oil passages pipeline, described respiratory siphon runs through breather tank, described respiratory siphon comprises and is positioned at the air-guide section of breather tank and is positioned at the free segment outside breather tank, the respiratory siphon that is positioned at free segment is provided with a Non-return air valve 4, the respiratory siphon that is positioned at air-guide section comprises the upper wireway that is positioned at breather tank upside and the downtake that is positioned at breather tank downside, between described upper wireway and downtake, be tightly connected, and on the tube wall of described upper wireway and downtake, offer some gas ports 5, the bottom of described breather tank offers air vent hole 9, and the bottom of described breather tank is connected with rubber closure 11 through back-moving spring 10.
In above-mentioned breather tank, be also provided with a circle in order to the electric heating assembly 6 of bake drying agent.
Between above-mentioned respiratory siphon and breather tank, by heat-resistant pressure-resistant sealing ring, seal 7.
The bottom of above-mentioned breather tank is outer lug boss structure, and air vent hole is positioned in outer lug boss, and the relative air vent hole of described rubber closure place is provided with sealing protuberance 8, and described rubber closure seals air vent hole when reset condition.
In implementation process, when the temperature rise of transformer interior oil, need to press in outer row, at this time by the respiratory siphon of respirator, internal gas is arranged outward by air vent hole, now, because interior pressure is larger, can back down back-moving spring, internal gas is discharged to outdoor from air vent hole, and owing to being provided with unidirectional valve in respiratory siphon, gas can not arranged from respiratory siphon; When interior pressure is too low, air enters into breather tank from the unidirectional valve of respiratory siphon, and the agent of air drying enters in transformer after dry, and wherein because interior pressure is little, back-moving spring can make rubber closure seal up air vent hole.
The foregoing is only preferred embodiment of the present invention, all equalizations of doing according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
