Hermetic space is formed between the back taper body and the back taper hole. Advantages are: simple structure and technique, high bonding strength, safety and reliable and wide application.
Description
Technical field
The present invention relates to a kind of method of attachment and a kind of insulator of insulator end accessory, particularly relate to departments such as to be widely used in electric power, railway, various length and size, organic composite material and the composite high voltage insulator of ceramic material and a kind of method of attachment of insulator end accessory thereof.
Background technology
Insulator is installed the security reliability that is connected with electric equipment, depends on the bonding strength and the engineering reliability of insulator end metal-ware and core rod of insulator.
The insulator of modern invention generally adopts the crimping method of the current international practice---is about in the borehole jack of synthetic material plug reeve end metal-ware, with special-purpose extrusion equipment metallic sheath is carried out the radial compression stationary core rod then, bonding strength depends on the frictional force of socket length and radial compression.The shortcoming of this method is that the length dimension of socket is very big, and is inapplicable to the insulator that length is less, and the hot strength that connects is limited, and fatigue failure takes place easily.
Also has a kind of internally wedged method of attachment, being about to plug socket position cuts in the tapered sleeve that injects metal-ware in the back, in the otch of plug, inject the internally wedged interconnection technique of chock then, the bonding strength height of this method, but can only be used for the less product of diameter of mandrel, and plug inside is torn because of interior wedging action easily and is caused interior insulation breakdown.
Also have the outer wedge-type socketing method of employing in addition, similar with internally wedged.
More than several methods of attachment in current application, mandrel fracture is arranged all the time or the accident that gets loose takes place.
In the traditional insulator end metal-ware and the interconnection technique of plug, what porcelain insulator adopted is with behind the porcelain core stick end socket position scab sintering, inject the inner metallic sheath that ring-shaped groove is arranged, and the method that pouring cement is solidified in the space, bonding strength depends on the shear strength after the socket degree of depth and the cement solidification.
The taper elastic lock sleeve that my company once succeeded in developing press-fits patented technology (patent of invention number 031142753, patent of invention number 0322542.3), though bonding strength height, technology are reliable, structure is complicated, and range of application is restricted.
Summary of the invention
First purpose of the present invention provides a kind of simple to operate, method of attachment of connecting reliable, widely used insulator end accessory
Second purpose of the present invention provides a kind of simple in structure, reliable, widely used insulator of connection.
A kind of method of attachment of insulator end accessory, insulator comprises insulating coating, plug, end accessory, the plug of insulator and the installation site of end metal-ware are made reverse taper and back taper hole respectively, reverse taper inserts the back taper hole, be filled with the filler that can solidify between the gap in reverse taper and back taper hole, plug and end metal-ware are fixed, and the gap between reverse taper and the back taper hole forms confined space.Be filled with the filler that can solidify between the gap in reverse taper and back taper hole, plug and end metal-ware are fixed.Insulator is being subjected to pulling force or crooked external force is done the time spent, produces crimp between the common normal in reverse taper and back taper hole.Because filler has Incoercibility in airtight cavity, reverse taper can not be pulled out in the back taper hole.The mechanical strength that connects depends on the shear strength of filler, and is directly proportional with diameter of mandrel and socket depth dimensions.
As the improvement of the inventive method, the filler that can solidify is cast between the gap in reverse taper and back taper hole.
As the further improvement of the inventive method, reverse taper be shaped as inverted cone or the little taper polyhedron of outer imperial palace, the back taper hole be shaped as the rounding taper hole; The top diameter of rounding taper hole is consistent with the maximum radial dimension of reverse taper major part.
A kind of insulator comprises insulating coating, plug, end accessory, and insulating coating is fixed on mandrel outer, and end accessory is enclosed within the two ends of plug, and the auxiliary section of plug and end accessory comprises the reverse taper and the back taper hole of working in coordination; The number of reverse taper is one or more, and the number in back taper hole is one or more; Reverse taper inserts in the back taper hole, is filled with the curing agent packing layer between reverse taper of working in coordination and back taper interporal lacuna.According to the size of core rod of insulator diameter and the structural requirement of end metal end annex, one link position wherein can be made the little reverse taper of outer imperial palace, big outer little back taper conical bore in another part is made.After reverse taper injects the back taper hole, use the filler that can solidify with both positioning and fixing.The mechanical strength that connects depends on the shear strength of filler, and is directly proportional with diameter of mandrel and socket depth dimensions.
As improvement, reverse taper be shaped as inverted cone or the little taper polyhedron of outer imperial palace, the back taper hole be shaped as the rounding taper hole.
As further improvement, the top diameter in back taper hole is consistent with the maximum radial dimension of reverse taper major part, is convenient to reverse taper is inserted in the back taper hole, after reverse taper injects the back taper hole, uses the filler that can solidify with both positioning and fixing.
As further improving again, reverse taper comprises the reverse taper that two or more are step-like, can improve the socket intensity of insulator end accessory at the corresponding diameter that strengthens the diameter of cone small end and under the situation of assurance chamfer length size, reduce the big end of conical bore accordingly under the situation that guarantees the chamfer length size like this
As another improvement, in reverse taper, also be provided with the back taper blind hole, also extension is provided with the protruding reverse taper that cooperates with the back taper blind hole in the back taper hole.When the diameter of mandrel of insulator is enough big, also can make combined type reverse taper interconnection technique, after being about to wherein one and making reverse taper, heart position increases the rounding taper hole more therein, the center that another part is then made the rounding taper hole increases a reverse taper again, all has curable filler to be adhesively fixed between the cooperation of two groups of big boccas.The mechanical strength of this compound connection is very big, can be used for the specific (special) requirements occasion.
As further improvement, on the end face of the two ends of plug, be provided with the back taper hole, on end accessory, be provided with the containing hole of ccontaining plug, in containing hole, extend and be provided with the reverse taper that cooperates with plug back taper hole, on the end face of containing hole, also be provided with the shoulder hole that cooperates with insulating coating, make end accessory more reliable with being connected of outer exhausted cover, plug.
As another improvement, on the end face of the two ends of plug, be provided with reverse taper, on end accessory, be provided with the containing hole of ccontaining plug, in containing hole, be provided with the back taper hole that cooperates with the plug reverse taper, on the end face of containing hole, also be provided with the shoulder hole that cooperates with insulating coating, make end accessory more reliable with being connected of outer exhausted cover, plug.
The inventive method has that technology is simple, bonding strength is high, safe and reliable, the advantage that has wide range of applications.
That insulator of the present invention has is simple in structure, bonding strength is high, safe and reliable, the advantage that has wide range of applications.
