Abstract
The utility model relates to a pressure release respirator of an oil-charging type electrical device, which is applied as a substitute for the respirators of the existing oil-immersed power transformer, the oil-immersed capacitor, the oil-immersed circuit breaker, the oil-immersed transformer and the like. The pressure release respirator comprises a root flange (1), a cylindrical cavity (21), filling silica gel (9) of the cylindrical cavity (21) and a tail-end oil seal part (19), and is characterized in that one hollow pipe (3) penetrates the central line of the cylindrical cavity (21), and fixes the root flange (1) and the oil seal part (19) respectively by threads; a plurality of small holes are arranged on the side of the pipe (3); the tail end of the pipe (3) is provided with a movable piston (13) which is under the action of a pressure spring (15); and the cavity (21) is provided with a feed nozzle (5) and a seal cover (7). The pressure release respirator has the advantages of low respiratory flow resistance and fast gas discharge and oil release when in high pressure.
Description
Affiliated technical field
The pressure that the utility model relates to the filling type electric equipment discharges respirator, is applied to substitute the respirator of existing oil-immersed power transformer, oil immersed type capacitor, oil-immersed breaker, oil immersed type instrument transformer etc.
Background technology
Oil-filled transformer, it has a respirator.Its effect is that inhaled air is removed moisture content, and is keeping under the airtight situation air above the insulating oil breathed out the external world.Suction and exhalation phenomenon that air occurs, genesis is in the rising and the reduction of oil temperature.Described respirator is installed on the oil-filled transformer vertically, and its root is a flange, and the middle part is a cylindrical cavity, fills a certain amount of silica gel in the chamber, and the art end is the oil sealing parts, and the middle part that solid hopkinson bar passes cavity is fixed up flange with the oil sealing parts.Its deficiency is when to be transformer because of internal fault cause the oil temperature sharply to raise, and all gases that the air in the enclosed cavity, insulating oil decompose etc. can not in time " be exhaled " to go out to outer bound pair enclosed cavity and be reduced pressure, and then the bigger transformer explosive damage power of generation.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, provides a kind of and can reduce pressure in good time, alleviate the pressure of the filling type electric equipment of explosive damage power to discharge respirator.
The purpose of this utility model can reach like this, the pressure of filling type electric equipment discharges respirator, form by root flange, cylindrical cavity and filling gel thereof, art end oil sealing parts, it is characterized in that a hollow pipe passes the cylindrical cavity center line and respectively root flange and oil sealing parts is fixed up by screw thread; The side direction of pipe is opened some apertures, and the end of pipe is the motion stops that is subjected to the stage clip effect; Cavity band one feed nozzle and seal cover thereof.
The utility model has following advantage compared to existing technology:
1, the respiratory air flow resistance is little;
Exhaust when pressing in 2, high, tell oil rapidly.
Description of drawings
Accompanying drawing is a structural representation of the present utility model
1 is that root flange 3 is that hollow pipe 5 is that feed nozzle 7 is that seal cover 9 is that discolour silica gel 11 is that sealing ring 13 motion stops 15 are that stage clip 17 is that oil sealing 19 is that oil sealing parts 21 are cavitys among the figure
Embodiment
The utility model is further described below in conjunction with accompanying drawing.The pressure of filling type electric equipment discharges respirator, form by root flange (1), cylindrical cavity (21) and filling gel (9) thereof, terminal oil sealing parts (19), it is characterized in that a hollow pipe (3) passes cylindrical cavity (21) center line and respectively root flange (1) and oil sealing parts (19) is fixed up by screw thread; The side direction of pipe (3) is opened some apertures, and the end of pipe (3) is the motion stops (13) that is subjected to stage clip (15) effect; Cavity (21) is with a feed nozzle (5) and seal cover (7) thereof.
When the air pressure on the inner pasta of transformer balanced each other with the external world, silica gel of the present utility model (9) can be subjected to the air moisture content absorption of oil sealing (17) sealing, prevented that oil Jie of transformer inside from becoming damp and rotten.When oily temperature rise was little, the air on the pasta was escaped out from numerous apertures of hollow pipe (3) side and is entered oil sealing parts (19) inside and pass oil sealing (17) and go out the external world.If oily temperature raises suddenly, all gases or oil be situated between directly promote motion stops (13) from hollow pipe (3) art port go out pass by screw thread be fixed on the terminal numerous apertures of fixed support side direction of hollow pipe (3) through oil sealing (17) to the external world, finish the purpose of decompression.Behind the internal and external pressure balance, stage clip (15) stretches, and motion stops (13) promotes sealing ring (11) hollow pipe (3) end port is blocked.When ambient pressure was situated between top pressure greater than oil, outside air passed oil sealing (17) and arrives silica gel (9), and enters from the numerous apertures in hollow pipe (3) side.Adsorbed by silica gel (9) after the air moisture content that newly advances.
Claims (1)
