Description
Technical field
The utility model relates to a kind of synthetic insulator with conical compression sealing ring.
Background technology
Synthetic insulator is a kind of equipment that is used on the ultra-high-tension power transmission line, and it mainly acts on is to be used for being connected of shaft tower and lead, and the weight of carrying lead also plays insulating effect between the two.Because powerful effect of electric field under the high-tension electricity, be easy to synthetic insulator is produced galvanic corrosion, atmospheric environment worsens in addition, a large amount of acid mist erosion year in year out in the air, particularly hold the sealing of neck to damage to synthetic insulator, make the plug in the synthetic insulator under the effect of galvanic corrosion and mist acid, cause the corrosion brittle failure, threaten for the safe operation of high-tension line.
At present, three kinds of seals style are adopted in the sealing of widely used synthetic insulator end neck:
A kind of is to seal with room temperature vulcanized silicone rubber, because the room temperature vulcanized silicone rubber electric erosion resistance is poor, and mechanical strength is relatively poor, very easily wrecks.
Two kinds is to adopt high-temperature silicon disulfide rubber to carry out integral sealing, and this encapsulating method is because high-temperature silicon disulfide rubber is wrapped in the inside with the end metal-ware, when external discharge takes place when very easily by electrical breakdown, thereby cause sealing destroyed.
And above-mentioned two kinds of sealings also have a common fatal shortcoming, and when the plug in the synthetic insulator and end metal-ware are subjected to displacement under external force, its sealing property will be destroyed by air.
The 3rd, a kind of sealing ring of built-in O RunddichtringO, this sealing means is little to the pressure of O type circle by outer ring body, and ring body adopts with the synthetic insulator end accessory and is threaded, and causes sealing effectiveness to guarantee thereby be easy to generate to become flexible.
Summary of the invention
The synthetic insulator that the purpose of this utility model provides a kind of simple in structure, good sealing effect, is connected firmly, electric erosion resistance can be good with conical compression sealing ring.
For achieving the above object, the utility model is taked following design:
A kind of synthetic insulator with conical compression sealing ring, it comprises insulator termination, insulator end neck, plug, core bar jacket, it is characterized in that: the place is socketed with conical compression sealing ring at insulator end neck, be socketed with conical sealing ring outside the sheath of the plug in the sealing ring, between the inner peripheral surface of the outer circumference surface of insulator end neck and sealing ring, be provided with the fastening spring coil of open type.
The inner peripheral surface of described sealing ring is provided with groove, is provided with corresponding groove on the outer circumference surface of insulator end neck, and the fastening spring coil of open type is set in two corresponding groove, is provided with annular convex shoulder at an end of the endoporus of sealing ring.
It is conical that the outer surface of described sealing ring is, and is the taper shape that corresponding matching is arranged on the inner peripheral surface of described insulator end neck.
The cross section of the fastening spring coil of described open type is circular arc or rectangular.
The external peripheral surface of conical compression sealing ring is semicircular in shape or half elliptic.
Conical compression sealing ring adopts metal material to make, and its effect is that conical silicone rubber O-ring is compressed, and is connected with synthetic insulator end neck, and it also has the effect of minor betterment electric field strength simultaneously; Conical sealing ring is under the annular convex shoulder pressure effect on the sealing ring, conical sealing ring also can make sealing ring produce normal pressure to synthetic insulator oversheath contact surface when moving vertically, thereby makes plug and the isolated better seal effect that reaches of extraneous air.Conical sealing ring adopt with silicon rubber be material of main part through the HTHP sulfidization molding, have preferably the elastic reactance ageing properties, electrocorrosion-resisting is strong; The cross section of the fastening spring coil of open type is circular arc or rectangular, its effect is that sealing ring and synthetic insulator end neck are connected firmly, and the pressure that makes the conical sealing ring of sealing ring is in a kind of state of maintenance, the great advantage of this locking mechanism is, removing the non-hermetic seal body is damaged, otherwise connected mode is in hold mode always.
The utility model has the advantages that:
1, good sealing effect, lasting, its sealing property is not easy to wreck;
Even 2 plug with the end neck take place under the situation of slight displacement, the sealing also can keep;
3, the distribution that seal ring body cylindrical arc can minor betterment electric field strength;
4, conical sealing ring adopts with silicon rubber HTHP sulfidization molding, and anti-aging, electrocorrosion-resisting is strong;
5, firm and reliable connection, operation is simple, and be difficult for destroyed;
6, applicable to various types of synthetic insulators.
