Abstract
The utility model belongs to a conductor static contact connection structure for a high-voltage switchgear and relates to a conductor static contact connection structure. The conductor static contact connection structure comprises a support and a straight-through conductor, wherein the support is sleeved on the straight-through conductor. The conductor static contact connection structure is special in that the straight-through conductor is provided with a groove, in which a spring contact finger is inserted. The device provided by the utility model has a simple structure, is convenient to assemble, requires low cost, has a large contact area, and is beneficial to reliable electric connection of a high-voltage switchgear. According to the design, a straight conducting rod and the spring contact finger are installed together and then are directly inserted into the support. A shielding cover, a petaloid contact finger and a compression spring are saved, and the shielding cover, the petaloid contact finger and the compression spring are replaced with a support. The conductor static contact connection structure has a simple structure, is beneficial to installation of a high-voltage switchgear, and is used to reduce space usage of contacts, increase insulation distance and even more raise security. The design is mainly applied in electrical switchgears of voltage classes of 126kV and above.
Description
(1) technical field
The utility model belongs to the quiet contact syndeton of conductor for high voltage switchgear, relates 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 while earth fault occurring, large electric current causes easily causes that loop resistance increases.
(3) summary of the invention
The utility model, in order to make up original connected mode deficiency, provides a kind of conductor simple in structure, dependable performance quiet contact syndeton.
The utility model is achieved by the following technical solution:
The quiet contact syndeton of a kind of conductor, comprise bearing and straight-through conductor, and bearing is enclosed within on straight-through conductor, and its special character is: on straight-through conductor, groove is set, inlays spring in this groove and touch fat.
The quiet contact syndeton of conductor of the present utility model, this spring touches fat and is enclosed within on straight-through conductor by groove.
The beneficial effects of the utility model are: apparatus structure of the present utility model is simple, easy to assembly, cost is low, contact area is large, is conducive to high voltage switchgear and reliably is electrically connected to.This design now is installed together straight conducting rod and the tactile fat of spring, then directly inserts in bearing, has saved radome, has broken the shape fingertip and tighten spring, with a bearing, has replaced radome, flap fingertip, has tightened spring.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) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 2 is structural representation of the present utility model;
In figure, 1 straight-through conductor, 2 radomes, 3 tighten spring A, and 4 break the shape fingertip, 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 utility model.This embodiment comprises straight-through conductor 1, the rear sleeve of straight-through conductor 1 has bearing 12, on straight-through conductor 1, groove is set, spring touches fat 11 and is embedded in the groove that leads directly to conductor 1, with bearing 12 inwalls, contact, 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 groove, then inserts on bearing 12, has easy for installationly, and accessory is easily processed, and cost is low.
This bearing 12 can be arranged on disc insulator, also can be arranged on straight-through conductor 1, makes it easy to connect, 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 beneficial effects of the utility model are, it is simple in structure, easy to assembly, cost is low, contact area is large, are conducive to high voltage switchgear and reliably are electrically connected to.This design now is installed together straight conducting rod 1 and the tactile fat 11 of spring, then directly inserts in bearing 12.The straight-through conductor 1 of conventional high-tension switch shielding contact base is connected with guide post 7, should outside straight-through conductor 1, by trip bolt 8, at its outside cover, radome 2 be arranged, shape fingertip 4 and contact base 6 are broken in the interior setting of radome 2, break shape fingertip 4 and contact base 6 and all be positioned at the outside that leads directly to conductor 1, this is broken on shape fingertip 4 and arranges and tighten 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 contact base 6, the front end of breaking shape fingertip 4 arranges insulation barrier 10, this insulation barrier 10 is placed in radome 2d inside.Device of the present utility model has saved radome 2, broken shape fingertip 4 and has tightened spring 3,5, with a bearing 12, has replaced radome 2, flap fingertip 4, has tightened spring 3,5.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.
