Abstract
The invention relates to a simple transformer respirator. The simple transformer respirator comprises a respiration tank filled with a drying agent. A respiration pipe connected with an oil way pipeline in a transformer is arranged in the respiration tank and penetrates through the respiration tank. The simple transformer respirator is characterized in that the respiration pipe comprises an air guide section located in the respiration tank and a free section located outside the respiration tank; the upper portion of the air guide section of the respiration pipe is provided with multiple air guide holes, the lower end of the free section of the respiration pipe is connected with a rubber sealing cover through a spring reset assembly, and the bottoms, located on the two sides of the respiration pipe, of the respiration tank are provided with one-way valves. An oil cup structure is omitted, product working performance cannot be affected when the respirator is transported and installed, and normal operation is guaranteed.
Description
Technical field
The present invention relates to a kind of plain type transformer breather, 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.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 plain type transformer breather.
Technical program of the present invention lies in:
A kind of plain type transformer breather, 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 top that is positioned at air-guide section is provided with some gas ports, the respiratory siphon lower end that is positioned at free segment is connected with rubber closure through spring reset assembly, and the breather tank bottom that is positioned at respiratory siphon both sides is provided with unidirectional valve.
Wherein, in described breather tank, be also provided with a corral around the electric heating assembly of respiratory siphon curl.
Between described respiratory siphon and breather tank, by heat-resistant pressure-resistant sealing ring, seal.
Described spring reset assembly comprises that two symmetries are bolted in the adjusting bolt bar of the respiratory siphon downside that is positioned at free segment, two described adjusting bolt bars are slidably connected with one end of rubber closure respectively, and between the termination of rubber closure and joint shank of bolt, be provided with back-moving spring, the back-moving spring under normality covers on the respiratory siphon lower end of free segment rubber closure.
The sealing of described rubber closure becomes to be beneficial to the trapezium structure of sealing.
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 plain type transformer breather, comprise the breather tank 1 that is equiped with drier 2, in described breather tank, 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 top that is positioned at air-guide section is provided with some gas ports 4, the respiratory siphon lower end that is positioned at free segment is connected with rubber closure 5 through spring reset assembly, the breather tank bottom that is positioned at respiratory siphon both sides is provided with unidirectional valve 6, under unidirectional valve normal condition, extraneous air could flow in breather tank.
In above-mentioned breather tank, be also provided with a corral around the electric heating assembly 7 of respiratory siphon curl.
Between above-mentioned respiratory siphon and breather tank, by heat-resistant pressure-resistant sealing ring, seal 8.
Above-mentioned spring reset assembly comprises that two symmetries are bolted in the adjusting bolt bar 9 of the respiratory siphon downside that is positioned at free segment, two described adjusting bolt bars are slidably connected with one end of rubber closure respectively, and between the termination of rubber closure and joint shank of bolt, be provided with back-moving spring 10, the back-moving spring under normality covers on the respiratory siphon lower end of free segment rubber closure.
The sealing of above-mentioned rubber closure becomes to be beneficial to the trapezium structure of sealing.
In implementation process, when the temperature rise of transformer interior oil, need to press in outer row, at this time the respiratory siphon by respirator by internal gas by arranging outside respiratory siphon lower end, now, because interior pressure is larger, can back down back-moving spring, make internal gas be discharged to outdoor from respiratory siphon lower end, and because breather tank bottom is provided with unidirectional valve, gas can not arranged from unidirectional valve; When interior pressure is too low, air enters into breather tank from the unidirectional valve of breather tank bottom, and the gas port by respiratory siphon top after the agent of air drying is dry enters in transformer, and wherein because interior pressure is little, back-moving spring can make rubber closure seal up respiratory siphon lower end.
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.
