Description
Technical field
The present invention relates to a kind of ehv power transmission equipment and production method thereof, particularly relate to a kind of column support type hollow combined insulator and production method thereof.
Background technology
Hollow combined insulator just progressively replaces traditional porcelain insulator and glass insulator with its superior electric property and mechanical performance.Particularly in superhigh pressure, extra-high voltage electric transmission and transformation equipment, the superior function of hollow combined insulator is embodied more.Hollow combined insulator is made up of three parts of connection gold utensil at insulation mandrel, silicon rubber umbrella cover and two ends.Connect gold utensil and be generally aluminium alloy flange, hollow combined insulator should be realized the sealed attachment of flange and plug, also need be connected with other annexes in its end usually again.At present, the termination flange inner wall that most of hollow combined insulator manufacturer adopts all is a cylinder type, as shown in Figure 2, the flange endoporus is inserted in the insulation mandrel termination of hollow combined insulator, adopts the agent of epoxy resin gluing to glue together and is tightly connected.The flange endoporus is a through hole, and the end face of the insulation mandrel inner core behind the mucilage binding is equal with the end face of flange.It with other annexes between to be connected sealing be to form triangular groove between the axial inwall of both end faces, indentation sealing circle in triangular groove is realized being tightly connected with other accessory kits.Because such hollow combined insulator has long length, bigger diameter, make the higher axiality of maintenance between insulation mandrel inner core and the flange, slit between two parts is very little and require the slit evenly to distribute in whole circumference, adds casting epoxy resin curing agent between the slit in man-hour.Therefore, the hollow combined insulator of this flange arrangement need be proofreaded the relative position of inner core and flange in process of production, guarantee the radial clearance requirement of inner core and flange, if deviation occurs in the check and correction, it is inhomogeneous that curing agent will be filled, even inabundant situation of filling appears, thus influence the sealing property of insulator, cause product defective.Because the two is a contactless garden tube, the benchmark of check and correction axiality is not provided itself, required in process of production proof time is long, has a strong impact on work efficiency and quality.
Summary of the invention
The purpose of this invention is to provide a kind of column support type hollow combined insulator, the air-tightness between its insulation mandrel inner core and the flange is strong, and mechanical strength is big.
Another object of the present invention provides a kind of production method of column support type hollow combined insulator, and the column support type hollow combined insulator of its subject of knowledge and the object of knowledge production has above-mentioned advantage, and has advantage of simple technology.
Technical scheme of the present invention is: column support type hollow combined insulator, it comprises insulation mandrel inner core, termination flange, silicon rubber umbrella cover, in the described insulation mandrel inner core insertion end head flange endoporus and coaxial fit, it is characterized in that: described termination flange endoporus be provided with the footpath inwardly ring offset with insulation mandrel inner core end face.
As to further improvement of the present invention, the described footpath inwardly upper surface of ring is provided with the axial notch coaxial with the termination flange, and described footpath inwardly is pressed with O type rubber seal between the axial notch on the ring and the insulation mandrel inner core end face.
As to further improvement of the present invention, the described footpath inwardly lower surface of ring is concordant with the flange lower surface, and the lower surface that described footpath is inwardly encircled is provided with seal groove.
As to further improvement of the present invention, the quantity of described seal groove is two.
As to further improvement of the present invention, the described footpath inwardly internal diameter of ring equates with insulation mandrel inner core internal diameter.
As to further improvement of the present invention, described insulation mandrel inner core and termination flange are tightly connected by the epoxy resin gluing agent that cast enters between both slits.
As to further improvement of the present invention, described insulation mandrel inner core is a fiberglass.
The production method of column support type hollow combined insulator, the step that is tightly connected that comprises termination flange and insulation mandrel inner core, the step that is tightly connected of its termination flange and insulation mandrel inner core is: offset with insulation mandrel inner core insertion end head flange endoporus and with the inside ring in its footpath earlier, proofread and correct axiality, again from flange upper end sprue gate cast adhesive, be heating and curing, finish being tightly connected of termination flange and insulation mandrel inner core.
As to further improvement of the present invention, described adhesive is the agent of epoxy resin gluing.
Beneficial effect of the present invention is:
1, because the present invention's flange is provided with inwardly ring of footpath, the insulation mandrel inner core can directly offset with it, be connected when cast with the insulation mandrel inner core carrying out the termination flange, the direct benchmark object of reference of the axiality that can be used as check and correction insulation mandrel inner core and flange is inwardly encircled in the footpath, greatly reduce the check and correction operation easier, reduce proof time in a large number, improved production efficiency.Contain insulation mandrel inner core end face because the footpath is inwardly encircled simultaneously,, improved the sealing intensity between inner core and the flange greatly for pressurization O type rubber seal between insulation mandrel inner core and termination metal flange provides condition.On the other hand, the footpath inwardly ring the wall thickness that has increased the flange bottom is set, strengthened the mechanical strength of flange, strengthened the anti-performance of tiltedly drawing of flange.
2, because termination metal flange bottom area strengthens, seal groove can be set, improve the sealing intensity between hollow combined insulator and other accessory kits.
3, because method provided by the present invention can directly inwardly be encircled the benchmark for check and correction termination flange and insulation mandrel inner core axiality, greatly reduce the check and correction operation easier, reduced proof time in a large number, improved production efficiency, simplify production technology, improved product quality.
