Advantages comprise that the connection hardware fitting can carry out continuous length adjustment according to practical engineering demands, and is wide in adjustment scope and accurate in dimension adjustment, thereby effectively guaranteeing the stress equilibrium of a lead duplex suspension insulator string, and making the line safer in long-term operation; and the connection hardware fitting is simple in processing, convenient in construction, and good in adjustability, and can provide good design and operation effects when being used in the line.
Description
Technical field
The utility model relates to a kind of connection gold utensil, especially relates to a kind of used for transmission line continuous adjustable and connects gold utensil.
Background technology
Along with increasing of transmission line construction, scissors crossing each other increases, the height of shaft tower increases, the discrepancy in elevation increases, the situation of the construction of transmission line and China's land resource anxiety has produced contradiction, now under the situation that situation allows, transmission line generally all will be avoided the residential block, the farmland, landform such as industrial area are local preferably, it is with a varied topography that this just causes transmission line to appear at, the discrepancy in elevation is big, the situation that span is big increases to some extent, also just cause using the situation of duplex suspension insulator to increase gradually, and under this orographic condition, directly adopt the isometric lead duplex string that dangles, can not reach desirable stressed effect.
Nonstandard gold utensil is mainly used in lead duplex suspension insulator when big discrepancy in elevation situation lower stress is unbalanced.At 220kV and following electric pressure this kind situation was not processed in the past, adopt the isometric lead of the two strings string that dangles, and the UJ(X that uses in 500kV line project in the past) the type gold utensil is not to be continuously adjustable yet, the UJ(X that in the 500kV line project, uses) type typing gold utensil, long to be divided into A, B, C, D, E, F, G etc. several from being short to, be not to be continuously adjustable, the amplitude of its adjusting is generally 20mm or 40mm, and is perhaps bigger.
Summary of the invention
The purpose of this utility model is to provide a kind of used for transmission line continuous adjustable to connect gold utensil, makes lead duplex suspension insulator reach rational stress, improves lead duplex suspension insulator load condition, guarantees the safe operation of circuit.
The purpose of this utility model is implemented by following technical scheme: a kind of used for transmission line continuous adjustable connects gold utensil, it includes U type screw, arm-tie, draw ring, high nut, spring washer and split pin, wherein said arm-tie is provided with three holes that are arranged side by side, wherein said U type screw penetrates in two holes, the wherein outside in three holes that are arranged side by side of described arm-tie, and fix by described high nut and described spring washer, described draw ring penetrate described arm-tie three holes that are arranged side by side wherein in the middle of the hole in, and fix by described high nut and described spring washer, wherein be respectively equipped with pin-and-hole at the two ends of described U type screw, described split pin is inserted described pin-and-hole and is fixed.
Described U type screw is made of round steel; Described draw ring is made of round steel.
The nonstandard gold utensil of the utility model, mainly increase and decrease the length of single insulator string string by the length of set screw, solve in the design at present under the more scabrous big discrepancy in elevation situation, the lead duplex string discontinuity equalization problem of dangling, make two insulator strings reach reasonable stress, improve twin insulator strings load effect, guarantee the safe operation of circuit.
Advantage of the present utility model: this connection gold utensil can carry out continuous length adjustment according to actual requirement of engineering, adjustable range is big, size adjustment is accurate, effectively guarantees the stress balance of lead duplex suspension insulator, makes circuit long-term in service safer.And this connection gold utensil processing is simple, easy construction, adjustability are good, and application in the line can be played good design and running effect.
