Description
Technical field
The utility model relates to power circuit stringing ironware, in particular as the electric armour clamp that connects insulator string.
Background technology
Existing 500kV and 750kV used for transmission line insulator string gold utensil adopt the split plate to realize that six divide wiring, have the shortcoming that the long parts of string are many, string length is long, weight is heavier, inconvenience is installed; Simultaneously, last two lead drainages of six roots of sensation sub-conductor are rolled off the production line and are drawn following time, can run into following two leads, can cause the wearing and tearing of lead when lead is swung.
The utility model content
The purpose of this utility model provide a kind of go here and there long reduce, parts are few, can not intersect the UHV transmission line duplex strain insulator string of running into during the wiring of six roots of sensation sub-conductor.
This novel purpose is achieved in that a kind of UHV transmission line duplex strain insulator string, comprise the hanging point gold utensil, insulator, two left sides of wearing the U-shaped link that hangs over together, right-hand member is hinged with hanging point gold utensil and towing plate one end respectively, the towing plate other end and triangle yoke plate one end are hinged, be hinged with two ball-eyes on the triangle yoke plate other end, the other end of each ball-eye is hinged with an insulator, the other end of each insulator connects the gold utensil string of same structure: the socket-clevis eye other end that is connected with insulator is fixed on the four eyed yoke plate, the four eyed yoke plate is connected with two changes, six yoke plates again, two become to be on six yoke plates on six holes that regular hexagon arranges and are connected with the different six roots of sensation pull bar of length through the right angle link plate respectively, and the six roots of sensation pull bar other end connects six roots of sensation sub-conductors (being that each pull bar connects a root lead through two U-shaped links) through two U-shaped links respectively; Also be fixed with equal pressing plate on the four eyed yoke plate, also be fixed with shading ring on two changes, six yoke plates.
When being used for angle tower, the L value in the corner outside is adjusted by the corner size.This engineering wire jumper all adopts straight the jumping.Six roots of sensation sub-conductor divides upper, middle and lower-ranking, and two gold utensil string length unanimities of every layer increase progressively by the length of prolongation pull bar with 390mm, step by step so that six roots of sensation wire jumper also is positioned on the orthohexagonal summit that the length of side is 450mm.Because last two lead drainage threads of six-multiple conductor draw following time, can run into following two leads, can produce fraying of lead when lead is swung, between downlead and prolongation pull bar, jumper wire spacing rod is installed and is fixed.
Compared with prior art, this novel main feature and advantage are:
1, the hanging point gold utensil still adopts Italian cake formula hanging point, and this hanging point compact conformation rotates flexibly, and is stressed reasonable, is particularly useful for the heavy icing area circuit;
2, string shape is arranged the mature technology of having used for reference 500kV compact and 750kV six division electricity transmission lines, adopts the combined integrate yoke plate to finish six division wirings, and it is long to have reduced string, and complete relatively integral type yoke plate has alleviated half weight again, has made things convenient for installation;
3, owing to after grading ring, shading ring, the electric pressure raising, grading ring main ring pipe size increases.Simultaneously,,, and satisfy the requirement of insulator string voltage distribution, grading ring and shading ring are separated design, independently finish its electric function separately grading ring main ring Guan Shangkang height for ease of layout because the connection spacing strengthens, the grading ring contour structures significantly increases.Because grading ring is designed to the split formula, shading ring is designed to wheel shape, arranges that along circuit grading ring can be installed at last, like this, can guarantee effectively that its anchor ring is injury-free, effectively realizes its electrical protection function after insulator string installs.
4, the duplex strain insulator-string adopts twin insulator strings, double hanging point, four eyed yoke plate in this insulator string is a vital part, requirement according to the insulator string heading spacing, above two bunch-hanged holes link to each other with insulator by socket-clevis eye, below two hanging holes be connected with following yoke plate by parallel link plate, according to the needs of connection, this four eyed yoke plate is designed to trapezoidal, satisfied by the transition connection of insulator string to lead.Consider the position of this yoke plate in insulator string, reserved the mounting hole site of grading ring in the upper end.
5, the duplex strain insulator-string becomes six yoke plates with two, because after the electric pressure lifting, the increase of lead division number, the structural design of this yoke plate need guarantee to connect back six roots of sensation sub-conductor and be distributed in uniform way on orthohexagonal each summit.For taking into account easy construction, this yoke plate is designed to two yoke plates of shape symmetry, connects one by bracing frame.Totally six bunch-hanged holes on two plates can effectively guarantee the distribution of strain insulator retaining, sub-conductor.Consider the position of this yoke plate in insulator string,, reserved the mounting hole site of shading ring in its lower end.Relative other extra high voltage line, shading ring is designed to the loop configuration perpendicular to circuit, and second shading ring is installed on the special lead spacer, and the vibration that the installation centering is all inconvenient, simultaneously long-term also can increase the fatigue of lead.This insulator string shading ring is installed on this yoke plate as load spare along circuit, can not apply any additional force to lead, also is convenient to construction simultaneously, installs.
The electrical test of gold utensil insulator string: whole string gold utensil has carried out three kinds of electrical tests such as corona test, voltage distribution test and radio interference test.Result of the test meets the demands.
