Abstract
The utility model relates to an insulation sealing end plug which comprises a main insulation body (1) and a top sealing flange (2) formed at one end of the main insulation body (1). A bottom sealing flange (3) is arranged at the other end of the main insulation body (1). An air exhaust device is arranged inside the main insulation body (1) in an embedded mode. The insulation sealing end plug is characterized in that air exhaust pipelines are winded inside insulation materials, gas generated in the electrical device is exhausted in real time on the condition that ordinary insulation is ensured, air pressure inside the device is ensured to be stable, the end plug sealing flange and the insulation materials are integrated, the machinery structure is reliable in intensity, and even in electric field intensity, at the same time installing and repair are convenient due to the fact that an external plug-in type electrical device can be assembled.
Description
Technical field
The utility model relates to a kind of insulated enclosure plug, especially relates to a kind of insulated enclosure plug.
Background technique
When the inner cone sleeve pipe of electrical equipment does not temporarily connect usually, need to guarantee by seal plug is installed the insulation of product.But due in installation process, the intraluminal gas of electrical equipment inner conical drogue can't emit, and seal plug is difficult to be in place; Be exactly in the equipment normal course of operation in addition, when its internal electric field changes, can produce intermittent discharge between seal plug and inner cone sleeve pipe conductor, if the arcing gas that produces can not get effective discharging, long-term accumulated, when reaching the certain pressure limit, seal plug can eject under pressure, and the equipment security of operation is constituted a threat to.The problems referred to above exist for a long time always, and equipment and personal safety are constituted a serious threat, and so far still are not resolved.
The model utility content
The utility model is mainly to solve the existing technical problem of prior art; Provide a kind of and guaranteed under the normal insulation condition, constantly the gas that produces in electrical equipment has been discharged a kind of insulated enclosure plug of the stable gas pressure in assurance equipment.
It is to solve the existing technical problem of prior art that the utility model also has a purpose; Provide that a kind of Mechanical Structure Strength is reliable, electric field strength is even, can join the electric equipment of external plug-in type simultaneously, facilitated a kind of insulated enclosure plug of installation and maintenance.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of insulated enclosure plug is characterized in that, comprises a major insulation body and the top seal flange that is molded over major insulation body one end, and the described major insulation body the other end is provided with the sealed bottom flange; Be provided with venting gas appliance in described major insulation body; This venting gas appliance is embedded in the major insulation body.
At above-mentioned a kind of insulated enclosure plug, described venting gas appliance comprises an outlet pipe that is wound in the shape of a spiral in the major insulation body, and described outlet pipe one end communicates with the external world around pass the top seal flange to major insulation body top; The described outlet pipe the other end communicates with the external world around pass the sealed bottom flange to major insulation body bottom; Described sealed bottom flange also is provided with a retaining ring on the lower end surface, is fixed with a piezometer ring in described retaining ring; Described piezometer ring cross section is U-shaped, and an end is fixed in retaining ring; The other end bend in retaining ring and bottom retaining ring and extends.
At above-mentioned a kind of insulated enclosure plug, the electrode that reduces electric field stress is installed all on described top seal flange and sealed bottom flange.
Therefore, the utlity model has following advantage: at the inner coiling gas exhaust piping of insulating material, guaranteeing under the normal insulation condition, constantly the gas that produces in electrical equipment is discharged, stable gas pressure in assurance equipment, described plug sealing flange and insulating material are one-body molded, and its Mechanical Structure Strength is reliable, electric field strength is even, simultaneously can join the electric equipment of external plug-in type, facilitate installation and maintenance.
Description of drawings
Accompanying drawing 1 is a kind of main TV structure schematic diagram of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail, in figure, major insulation body 1, top seal flange 2, sealed bottom flange 3, outlet pipe 4, isolation layer 5, retaining ring 7, piezometer ring 8.
Embodiment:
The utility model comprises a major insulation body 1 and the top seal flange 2 that is molded over major insulation body 1 one ends, and described major insulation body 1 the other end is provided with sealed bottom flange 3; Be provided with venting gas appliance in described major insulation body 1; This venting gas appliance is embedded in major insulation body 1.Major insulation body 1 adopts solid insulating material to make, and the electrode that reduces electric field stress all is installed on top seal flange 2 and sealed bottom flange 3, and major insulation body and described sealing flange seat are shaped to one.Its Mechanical Structure Strength is reliable, electric field strength is even, can join the electric equipment of external plug-in type simultaneously, facilitates installation and maintenance.
Venting gas appliance comprises an outlet pipe 4 that is wound in the shape of a spiral in major insulation body 1, and outlet pipe 4 one ends communicate with the external world around pass top seal flange 2 to major insulation body 1 top; Described outlet pipe 4 the other ends communicate with the external world around pass sealed bottom flange 3 to major insulation body 1 bottom.Therefore guaranteeing under the normal insulation condition, venting gas appliance can be discharged the gas that produces in electrical equipment constantly, the stable gas pressure in assurance equipment.
In addition, for assurance equipment contacts constantly with plug bottom maintenance, the sealed bottom flange also is provided with a retaining ring 7 on 3 lower end surfaces, is fixed with a piezometer ring 8 in retaining ring 7; Piezometer ring 8 cross sections are U-shaped, and an end is fixed in retaining ring 7; The other end bend in retaining ring 7 and extends to retaining ring 7 bottoms.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more used the terms such as major insulation body 1, top seal flange 2, sealed bottom flange 3, outlet pipe 4, retaining ring 7, piezometer ring 8, do not get rid of the possibility of using other term.Using these terms is only in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
