Abstract
The related hang-type composite insulator comprises the mandrel with outside umbrella-skirt sheath and end members. Wherein, it uses the orientated glass fiber as mandrel reinforced body material, and applies soft insulation rubber or plastics to bond the mandrel. This invention has well reliability and smudges resistance, and can prolong service time greatly.
Description
Technical field
The present invention relates to a kind of composite insulator that is used for power circuit or electric railway circuit, particularly a kind of suspended compound insulator.
Background technology
Insulator is generally made by the high insulator material of resistance, and its effect is that current potential conductor inequality is separated, and not allowing has electric current to pass through between the conductor, and electric current can be circulated by certain direction.At present, suspension insulator is divided into ceramic insulator, glass insulator, composite insulator both at home and abroad.Pottery and the easy embrittlement of glass insulator, vulnerable to pollution causes high pressure flashover and the cracked accident of fried bottle easily; Flexible poor, the easily embrittlement of the anti-folding of the plug of common clavate composite insulator.
The end accessory of insulator is the part that is connected and fixed of insulator and power transmission line, electric pole, not only to bear the pressure of intrasystem various external force, lead self generation, in long-term use, also to bear the wind-force of indefinite direction and the pressure of accumulated snow, therefore the quality of connection of end accessory and plug is to be directly connected to the fail safe of product operation and the important symbol of reliability, usually adopt the plug and the end accessory interconnection technique of the production of compression joint type assembly technology, embrittlement takes place easily, easily get loose, wear out, and there is potential safety hazard in poor stability.
Summary of the invention
The objective of the invention is to problem and shortage, a kind of suspended compound insulator with flexibility, good pollution resistance, portability, flexible, the anti-embrittlement of anti-folding is provided at above existence.
Another object of the present invention provides a kind of bonding strength height, good stability, is difficult for wearing out the suspended compound insulator of safety durable.
Technical scheme of the present invention is achieved in that
A kind of suspended compound insulator, comprise plug, be located at the full skirt cover of mandrel outer and be located at the end assembly at plug both ends, wherein, plug is done to strengthen material of main part by directional glass fiber, and electro-insulating rubber material or the flexiplast by softness becomes bar as adhesives again.
In order to improve the withstand voltage and anti-pollution characteristic of full skirt cover, the full skirt cover adopts insulating polymeric material to make, and insulating polymeric material can be materials such as silicon rubber, ethylene propylene diene rubber or soft plastic.Full skirt cover is Unitarily molded on the plug or be socketed on the plug.
Further technical scheme of the present invention is achieved in that
The end assembly comprises the awl muzzle, can insert the enlarging cone, locking nut and the connector that embed in the plug, wherein: the enlarging cone is substantially cone, the awl muzzle is a tubular member, endoporus or the interference fit consistent of the miner diameter end of awl muzzle with diameter of mandrel, the endoporus of the bigger diameter end of awl muzzle is set to toroidal, and the hole wall of toroidal is provided with internal tooth, and the outer toroid of bigger diameter end is provided with the boss rank; Locking nut one end endoporus is provided with the concave station rank that cooperate with the boss rank, and locking nut other end endoporus is provided with internal thread; Connector one end is provided with the external screw thread that screws mutually with internal thread, and the other end adopts bulb shape or ball-and-socket shape or suspension ring shape; More stable for the end assembly is connected with plug, on the assembly of end, also be arranged with grading ring.
Plug of the present invention makes to strengthen material of main part by directional glass fiber, electro-insulating rubber material or flexiplast by softness becomes bar as adhesives again, make insulator have flexibility and reliable bonding strength, have good pollution resistance, portability, fracture or the fatigue fracture of wind pendulum can not bend in transportation with in using, effectively avoided the generation of high pressure flashover or the cracked accident of fried bottle, the cycle in useful life of having improved product; Again because the present invention has adopted the version of above-mentioned end assembly, adopt this cone enlarging interconnection technique to make the bonding strength of end assembly and plug be higher than the bonding strength of conventional crimp technology, plug was difficult for getting loose in the assembly of end when insulator used, and fracture or wind pendulum fatigue fracture phenomenon that stress fatigue or defective workmanship cause can not occur; The big I of the flexible diameter of mandrel of the present invention is according to the tensile load size decision of product; The type of the length of suspended compound insulator, the quantity of umbrella cover and shape, end assembly is according to antipollution grade and handling characteristics decision; The present invention can satisfy the instructions for use of the various classes of insulation and strength grade; All be better than existing link insulator or bar type composite insulator at aspects such as useful life, security reliabilities.
The present invention is further illustrated below in conjunction with accompanying drawing.
