Abstract
The utility model relates to an integral 757mm 110kV dry type cable terminal, and belongs to cable accessories in a high-voltage power transmission system. The integral 757mm 110kV dry type cable terminal is composed of an upper fitting, a movable contactor, an epoxy sleeve, a stress cone, a connecting flange, a spring compressing device, a tail pipe, a grounding terminal and a sealing ring, wherein the epoxy sleeve is poured in vacuum and molded in one step by adopting an epoxy insulator and an embedded sleeve electrode; the outer surface at one end of the movable contactor is embedded with two annular spiral spring contacts and keeps elastic contact with the upper fitting, and the other end is connected with a cable core, buckled and fixed with the cable core; the movable contactor can be plugged in and pulled out from the upper fitting; and the tail pipe is an aluminum pipe being externally sprayed with a fluorocarbon paint protection layer. The integral 757mm 110kV dry type cable terminal has the advantages of simple structure, convenient installation, multiple contacts, good conductivity and good stability.
Description
Technical field
The utility model relates to the electric cable accessories in high voltage power transmisson system.
Background technology
Overall 757mm110kV dry cable terminal is an one for dry cable terminal, is mainly used in the power consumption equipments such as appliance switch, transformer and is connected with the circuit of service cable, and be fixed in the housing of power consumption equipment.Its connected mode is that external cable reliably contacts with circuit in power consumption equipment and conducts electricity through moving contactor, top gold utensil.Visible, in moving contactor with cable core, outer be necessary assurance with reliable contact of top gold utensil, 757mm110kV dry cable terminal should meet IEC60859, GB/T 22381 gas-insulated GIS terminal standard interface requirements.This terminal has two kinds of interface sizes with power consumption equipment connecting interface by IEC60859, GB/T 22381 standards: one is that 470mm highly coordinates, and one is that 757mm highly coordinates.At present, the dry cable terminal product that domestic 757mm highly coordinates is less, is the non-dry type structure containing dielectric mostly, even if there is the cable termination of minority 757mm dry construction, is also to lengthen after top gold utensil entirety reaches 757mm and substitute use with 470mm.Moving contactor generally adopts with the top gold utensil way of contact, and outer wall around the home " watchband type " fingertip contacts to realize with maintenance and upper electrode." watchband type " fingertip series copper alloy lamellar rectangle wrapping machine adds compressing, and it relies on the elastic deformation of each unit that contact is provided, and forms plug-in connected mode.In addition, the tail pipe of known 110kV dry cable terminal is the sandblast of aluminium casting outer surface and makes.
Above-mentioned 110kV dry cable terminal has the following disadvantages in manufacturing and using practice: 1, conductor is exposed long, and insulation effect is low, poor stability.Also there is the hidden danger of loose contact.2, moving contactor outer wall " watchband type " fingertip around the home, because profile is that machining accuracy and the quality of fit of Rectangular Spring to its embedding slot had relatively high expectations, long-term use easily causes the compression set of " watchband type " fingertip and loose contact produces electric discharge and cause the fault frequency to increase.3, the cable protection pipe of the noisy processing of aluminium type casting moulding outer surface spray, outward appearance is coarse, and easily trapped fuel dirt is not easy to clean.
Summary of the invention
The purpose of this utility model is to provide a kind of low cost of manufacture, easy for installation, reliable overall 757mm110kV dry type GIS cable termination.
For achieving the above object, the technical solution of the utility model is to provide a kind of overall 757mm110kV dry type GIS cable termination, it consists of top gold utensil, epoxy bushing, moving contactor, stress cone, adpting flange, spring attachment, tail pipe, earth terminal, O type circle, and wherein said epoxy bushing is by epoxy insulator and be nested with pipe electrode vacuum pouring one-shot forming.Moving contactor one end outer surface is embedded with two garter spring fingertips and keeps Elastic Contact with top gold utensil, and other end stube cable core is withheld fixing.Moving contactor can plug at top gold utensil inner chamber.Tail pipe is that aluminum hull sprays fluorine carbon paint overcoat outward.
With known technology comparison, the utility model entirety 757mm structure meets standard fit dimension, meets user's non-lengthening conductor size to 757 cooperation demand, electrode and epoxy insulator vacuum pouring moulding in epoxy bushing.Two garter spring fingertips that moving contactor outer surface is embedded with, its material selection elasticity and high conductive copper alloy silk, helical spring distortion provides the contact of contact point and carries rated current, dynamic and thermal stability electric current.Spring is under working deformation in a big way, and the pressure of contact point changes less, and contact resistance variation is little, electric performance stablity.The small variations that spring touch finger manufacturing tolerance and fingertip are set groove dimensions is very little on its electric conductivity impact.It is simple in structure, size is little, easy for installation, contact point is many, conduct electricity very well, discharge capacity is large, electronic and thermal stability is high, it is little to wear and tear, can meet plug action need 10000 times.The moving contactor other end adopt outer wall that mechanical clasps presses contactor with guarantee with its simple in structure, easy manufacture of close contact of cable core, easy to install rapidly, coordinates reliably tight, thereby product total quality is improved, extend useful life, and maintenance cost reduces.Tail pipe is die casting aluminum hull, and shell sprays fluorine carbon paint overcoat outward, has good Corrosion Protection, non-maintaining, outside light, and automatically cleaning, has improved the product quality of overall terminal.More than improve and not only can meet serviceability and can meet IEC60859, GB/T 22381 standard fit dimensions.
