Abstract
The invention provides a pressure stabilizing device for an electronic sealing device. The pressure stabilizing device is that a sealing capsule made from memory alloy is arranged in insulating oil of the pressure stabilizing device. The sealing capsule is formed by connecting upper-portion memory alloy and lower-portion memory alloy in a sealing mode, and the surface of the memory alloy is corrugation-shaped. The pressure stabilizing device can remain pressure inside the pressure stabilizing device unchanged and achieve the purpose of prolonging the service life.
Description
Technical field
The present invention relates to a kind of device of the steady pressure for the electronic seal device, while being specifically related to a kind of externally pressure variation, change in time own vol, remain the device that external pressure does not change.
Background technology
In the electronic seal device, usually use the insulating oil medium to guarantee its service behaviour.But, along with the variation of temperature, the volume of built-in electrical insulation oil medium can produce corresponding variation, when ambient temperature during higher than normal temperature, the volumetric expansion of insulating oil medium, inside of electronic component pressure increases, and this can reduce its mechanical strength; When ambient temperature during lower than normal temperature, insulating oil medium volume contraction, inside of electronic component pressure reduces, and can form air gap, and this will reduce its insulation property.
Summary of the invention
Have for electronic seal device of the prior art the deficiency that mechanical strength reduces and insulation property reduce, the invention provides a kind of device of the steady pressure for the electronic seal device.
The device of the steady pressure for the electronic seal device of the present invention, contain following content: the seal capsule that memorial alloy is made is arranged in the insulating oil of electronic seal device.
Described seal capsule is tightly connected and is formed by upper and lower two parts memorial alloy, and the surface configuration of memorial alloy is bellows-shaped.
The memorial alloy of two parts up and down that forms seal capsule is respectively half capsule shape with limit, complete cycle outer.
The principle of device of the steady pressure for the electronic seal device of the present invention is: the seal capsule that described device is comprised of memorial alloy, it is positioned in the insulating oil medium of electronic seal device, when ambient temperature during higher than normal temperature, the volumetric expansion of insulating oil medium, external pressure increases the top that makes the steady pressure device and divides memory alloy and bottom to divide the corrugated surface of remembering alloy the super-elasticity contraction to occur, thereby keep electronic seal device inside pressure constant, prevent that pressure from increasing.When ambient temperature during lower than normal temperature, insulating oil medium volume contraction, external pressure reduces the top that makes the steady pressure device and divides memory alloy and bottom to divide the corrugated surface of remembering alloy the super-elasticity expansion to occur, thereby keeps electronic seal device inside pressure constant, prevents that pressure from reducing.
The device of the steady pressure for the electronic seal device of the present invention on the basis of existing technology, utilizes the super-elasticity geometry deformation characteristics of memorial alloy to keep electronic seal device inside pressure not change.
The ambient temperature of experiencing when the electronic seal device is during higher than normal temperature, its built-in electrical insulation oil medium volumetric expansion, the super-elasticity contraction appears in the corrugated surface that external pressure increases the seal capsule that makes the steady pressure be comprised of memorial alloy, thereby avoids because electronic seal device inside pressure increases the possibility that causes mechanical strength to reduce.The ambient temperature of experiencing when the electronic seal device is during lower than normal temperature, insulating oil medium volume contraction, the external pressure minimizing makes the top of steady pressure device divide memory alloy and bottom to divide the corrugated surface of remembering alloy the super-elasticity expansion to occur, thereby produces the possibility that air gap causes insulation property to reduce while avoiding reducing due to electronic seal device inside pressure.Reach and extend the electronic seal device purpose in useful life.Be positioned in the insulating oil medium of electronic seal device, keep electronic seal device inside pressure not change.
The accompanying drawing explanation
Fig. 1 is the cutaway view of the initial free state of the memorial alloy seal capsule in the present invention;
Fig. 2 is the cutaway view of the super-elasticity contraction state of the memorial alloy seal capsule in the present invention;
Fig. 3 is the cutaway view of the super-elasticity expansion state of the memorial alloy seal capsule in the present invention.
Embodiment
Fig. 1 is the cutaway view of the initial free state of the memorial alloy seal capsule in the present invention, and in Fig. 1, top divides memory alloy 1 and bottom to divide memory alloy 2 to be sealed connected together by welding limit, outer.Particularly, it is free bellows-shaped 1a that the surface configuration of remembering alloy 1 is divided on top, and it is free bellows-shaped 2a that the surface configuration of remembering alloy 2 is divided in bottom.It is all half capsule shape with limit, complete cycle outer that top divides memory alloy 1 and bottom to divide memory alloy 2.
Fig. 2 is the cutaway view of the super-elasticity contraction state of the memorial alloy seal capsule in the present invention, and in Fig. 2, the seal capsule that divides memory alloy 1 and bottom to divide memory alloy 2 to form on top is positioned in the insulating oil medium of electronic seal device.When ambient temperature during higher than normal temperature, the volumetric expansion of insulating oil medium, external pressure increases the top that makes the steady pressure device and divides memory alloy 1 and bottom to divide the corrugated surface of remembering alloy 2 the super-elasticity contraction to occur, wherein, top divides the free bellows-shaped 1a that remembers alloy 1 to become dark bellows-shaped 1b, bottom divides the free bellows-shaped 1a that remembers alloy 2 to become dark bellows-shaped 2b, thereby keep electronic seal device inside pressure constant, prevent that pressure from increasing, avoid because electronic seal device inside pressure increases the possibility that causes mechanical strength to reduce.
Fig. 3 is the cutaway view of the super-elasticity expansion state of the memorial alloy seal capsule in the present invention, and in Fig. 3, the seal capsule that divides memory alloy 1 and bottom to divide memory alloy 2 to form on top is positioned in the insulating oil medium of electronic seal device.When ambient temperature during lower than normal temperature, insulating oil medium volume contraction, external pressure reduces the top that makes the steady pressure device and divides memory alloy 1 and bottom to divide the corrugated surface of remembering alloy 2 the super-elasticity expansion to occur, wherein, top divides the free bellows-shaped 1a that remembers alloy 1 to become shallow corrugated shape 1c, bottom divides the free bellows-shaped 1a that remembers alloy 2 to become shallow corrugated shape 2c, thereby keep electronic seal device inside pressure constant, prevent that pressure from reducing, produce the possibility that air gap causes insulation property to reduce while avoiding reducing due to electronic seal device inside pressure.
Memorial alloy in embodiment of the present invention adopts Ultimum Ti.
