Abstract
The invention belongs to conductor static contact connection structures applied to high voltage switchgears and relates to a conductor static contact connection structure which comprises a support base and a straight-through conductor, wherein the support base is sleeved on the straight-through conductor. The conductor static contact connection structure is characterized in that grooves are arranged on the straight-through conductor, and spring contact resin is embedded into the grooves. The conductor static contact connection structure is simple in structure, convenient to assemble, low in cost and large in contact area and is favorable for reliable electric connecting of the high voltage switchgears. The straight conducting rod and the spring contact resin are installed together and then inserted into the support base, and shielding covers, split contact fingers and compression springs are omitted and are replaced by the support base. The conductor static contact connection structure has the advantages of being simple in structure, being favorable for installing of the high voltage switchgears, reducing space occupation of contacts, increasing the insulation distance and improving safety, and is mainly applied to electric apparatus switchgears at126kV and more voltage grades.

(1) technical field
The invention belongs to high voltage switchgear with the quiet contact syndeton of conductor, relate to the quiet contact syndeton of a kind of conductor.
(2) background technology
At present, the quiet contact of 126kV and above high-voltage switch gear conductor connects most of radome, flap fingertip, contact base of adopting, and the flap fingertip tightens with tightening spring.Its complex structure, manufacturing cost is high, wear no resistance, the assembling take a lot of work, time-consuming.The heating that large electric current causes when earth fault occurring causes that easily loop resistance increases.
(3) summary of the invention
The present invention is not enough in order to remedy original connected mode, provides a kind of conductor simple in structure, dependable performance quiet contact syndeton.
The present invention is achieved through the following technical solutions:
The quiet contact syndeton of a kind of conductor comprises bearing and straight-through conductor, and bearing is enclosed within on the straight-through conductor, and its special character is: on the straight-through conductor groove is set, inlays spring in this groove and touch fat.
The quiet contact syndeton of conductor of the present invention, this spring are touched fat and are enclosed within on the straight-through conductor by groove.
The invention has the beneficial effects as follows: apparatus structure of the present invention is simple, and is easy to assembly, cost is low, contact area is large, is conducive to high voltage switchgear and reliably is electrically connected.This design now is installed together straight conducting rod and the tactile fat of spring, then directly inserts in the bearing, has saved radome, breaks the shape fingertip off with the fingers and thumb and has tightened spring, has replaced radome, flap fingertip, has tightened spring with a bearing.Have simple in structurely, be conducive to high voltage switchgear and install, and reduced taking up room of contact, increased insulation distance, more improved fail safe.This design is mainly used in the electrical switchgear of 126kV and above.
(4) description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Accompanying drawing 2 is structural representation of the present invention;
Among the figure, 1 straight-through conductor, 2 radomes, 3 tighten spring A, and 4 break the shape fingertip off with the fingers and thumb, and 5 tighten spring B, 6 contact bases, 7 guide posts, 8 trip bolts, 9 insulating boards, 10 insulation barriers, 11 springs touch fat, 12 bearings.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises straight-through conductor 1, the rear sleeve of straight-through conductor 1 has bearing 12, on the straight-through conductor 1 groove is set, spring touches fat 11 and is embedded in the groove that leads directly to conductor 1, contact with bearing 12 inwalls, making its bearing 12 inwalls is smooth state, has greatly reduced man-hour such as difficulty of processing, precision size etc., has reduced processing capacity adding.
Preferred version is, directly at straight-through conductor 1 groove of getting on the bus, makes spring touch fat 11 and directly is enclosed within on the groove, then inserts on the bearing 12, has easy for installationly, and accessory is easily processed, and cost is low.
This bearing 12 can be installed on the disc insulator, also can be installed on the straight-through conductor 1, makes it easy to connect, and is simple in structure, is convenient to the characteristics such as heat radiation.Improved through-current capability, for the safe operation of product provides guarantee.
The invention has the beneficial effects as follows, it is simple in structure, and is easy to assembly, cost is low, contact area is large, is conducive to high voltage switchgear and reliably is electrically connected.This design now is installed together straight conducting rod 1 and the tactile fat 11 of spring, then directly inserts in the bearing 12.The straight-through conductor 1 of conventional high-tension switch shielding contact base is connected with guide post 7, should radome 2 be arranged straight-through conductor 1 outer overlapping in its outside by trip bolt 8, shape fingertip 4 and contact base 6 are broken in radome 2 interior settings off with the fingers and thumb, break shape fingertip 4 and contact base 6 off with the fingers and thumb and all be positioned at the outside that leads directly to conductor 1, this is broken off with the fingers and thumb to arrange on the shape fingertip 4 and tightens spring 3,5, this tightens spring 3,5 comprise and tighten spring A3 and tighten spring B 5, tighten spring A3 and be positioned at the front that tightens spring B 5, break installing insulating cardboard 9 between shape fingertip 4 and the contact base 6 off with the fingers and thumb, the front end of breaking shape fingertip 4 off with the fingers and thumb arranges insulation barrier 10, and this insulation barrier 10 places radome 2d inner.Device of the present invention has saved radome 2, broken shape fingertip 4 off with the fingers and thumb and has tightened spring 3,5, has replaced radome 2, flap fingertip 4, has tightened spring 3,5 with a bearing 12.Have simple in structurely, be conducive to high voltage switchgear and install, and reduced taking up room of contact, increased insulation distance, more improved fail safe.This design is mainly used in the electrical switchgear of 126kV and above.
Claims (2)
