Abstract
A built-in tubular conductor connector comprises a connecting conductive tube, spring contact fingers and hexagon socket-head cap screws, the conductive tube is connected with bus conductors through the spring contact fingers, and the number of the used spring contact fingers and the turn number of each spring contact finger are designed according to current rating. The connection mode mainly has the following advantages: (1) the affection of thermal expansion and cold contraction on the contacted parts of the conductors is reduced; (2) the contact resistance of the connected parts of the conductors can be kept constant for a long time; (3) the built-in tubular conductor connector can take the place of the retractable device used in bus laying; (4) the peripheral dimensions of the conductors are not affected, and insulated tubular buses can be conveniently insulated. The tubular conductor connection mode provides a tubular conductor connection scheme which has the advantages of reliable connection and high safety coefficient.
Description
Technical field
This utility model relates to the jockey between a kind of tubular conductor, and particularly a kind of built-in tubular conductor jockey belongs to equipment for power transmission and distribution.
Background technology
Jockey between the tubular conductor is an indispensable important link in the insulated tube bus series of products application process.Be 2～40.5kV all insulation pipe bus and semi-insulating pipe bus-bars conductor specifically with conductor between be connected a requisite cover link, the performance of insulated tube bus series of products is had very big influence.
At present, in the change of electric power system, power distribution station, the used bus of main transformer low-pressure side is main with rectangular conductor mainly.The skin effect coefficient of single rectangular conductor is less, and supplementary load loss are low, but ampacity is limited, therefore, is applicable to that generally electric current is the loop use below the 2000A; Need adopt the multi-slice rectangle conductor parallel way to improve ampacity for satisfying the ampacity requirement, because multi-disc conductor skin effect coefficient big than monolithic conductor, so supplementary load loss increase.Therefore ampacity is not counted increase and is formed doubly and increase along with conductor piece, and especially every when above above three mutually, the skin effect coefficient of conductor enlarges markedly.Conductor should be selected the tubular conductor of the low moulding of skin effect coefficient in practical engineering application.
For solving the connectivity problem between the tubular conductor, make things convenient for the insulation processing at all insulation pipe bus and semi-insulating tube bus connector position, the connected mode of tubular conductor just becomes a problem that must solve.Connection between the conductor is main with contact method with the welding dual mode mainly.All insulation pipe bus and semi-insulating pipe bus outer surface all are wrapped in insulating material, adopt welding can burn out insulating material, and the uneven of welding position causes point discharge to damage insulating barrier destruction safety of products easily.At present common contact method connection exists connection reliability not high, and expanding with heat and contract with cold during conductor work can influence the switching performance of jockey.
Summary of the invention
Goal of the invention: this practical purpose provides a kind of built-in tubular conductor jockey reliable, that coefficient of safety is high that connects, and can be used for all insulation pipe bus and semi-insulating pipe bus, can also be practical as retractor device.Not only solve tubular conductor connectivity problem, and solved the problem of expanding with heat and contract with cold of conductor.
Technical scheme: a kind of built-in tubular conductor jockey comprises the spring touch finger of the contact tube, the tubular conductor inwall of connection and the contact tube that place tubular conductor inside to be used to connect tubular conductor and is used for fixing tubular conductor and the set bolt of contact tube axial location; The tube wall of said tubular end conductor is provided with installing hole; The overall dimension of said contact tube is less than the inside dimension of tubular conductor; The contact tube tube wall is provided with at least two counterbore is installed, and the tube wall outside of said contact tube is provided with two cannelures that are used for the mounting spring fingertip at least.
Said spring touch finger is the ring spring that the coiling of metallic conduction material forms.
The external diameter of spring touch finger was higher than cannelure when said spring touch finger was installed in the cannelure of contact tube, and the shape of said cannelure bottom land is consistent with shape after spring touch finger compresses.
Beneficial effect: the utility model connects contact tube and bus-bars conductor through spring touch finger, according to the usage quantity of current class design spring touch finger and the number of turn of single spring touch finger.This kind connected mode mainly contains following some advantage: 1, reduce because of expanding with heat and contract with cold to the influence of conductor contact site; 2, keep the contact resistance of conductor coupling portion position constant for a long time; 3, can substitute bus and lay the middle retractor device that uses; 4, do not influence the conductor Outside Dimensions, make things convenient for the insulation processing of insulated tube bus.The tubular conductor connected mode of this kind provides a kind of connection reliable, the tubular conductor connectivity scenario that coefficient of safety is high.

Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
As shown in the figure; A kind of built-in tubular conductor jockey comprises the contact tube 2 that places tubular conductor 1 inside to be used to connect tubular conductor 1, connects the spring touch finger 3 of tubular conductor 1 inwall and contact tube 2 and is used for fixing the set bolt 4 of the axial location of tubular conductor 1 and contact tube 2; The tube wall of said tubular conductor 1 end is provided with installing hole 11; The overall dimension of said contact tube 2 is less than the inside dimension of tubular conductor 1; Contact tube 2 tube walls are provided with at least two counterbore 21 are installed, and the tube wall outside of said contact tube 2 is provided with two cannelures 22 that are used for mounting spring fingertip 3 at least.The ring spring that said spring touch finger 3 forms for the coiling of metallic conduction material.The external diameter of spring touch finger 3 was higher than cannelure 22 when said spring touch finger 3 was installed in the cannelure 22 of contact tube 2, and the shape of said cannelure 22 bottom lands is consistent with shape after spring touch finger 3 compresses.
The shape of the cannelure 22 that open on contact tube 2 surfaces must be consistent with the shape after spring touch finger 2 compressions; Trench bottom needs fine the contact with spring touch finger 3; Spring touch finger 3 is put into contact tube 2 grooves and is guaranteed that certain compression stroke is arranged, and keeps in touch spring 3 and flexible contact of tubular conductor 1 inwall.According to the usage quantity of current class design spring touch finger 3 and the number of turn of single spring touch finger 3.
