Description
Technical field
The utility model relates to a kind of insulation control, and more specifically, it relates to a kind of composite cross-arm insulator.
Background technology
Composite insulator is the polymer composite insulator adopting the support of ring oxygen leading-drawing rod, silicon rubber umbrella skirt external insulation. This product is compared with traditional pottery, category of glass insulator, have weight light (being only 1/4 to the 1/8 of same purposes conventional insulators), intensity height more than 10 times of high-strength ceramic (leading-drawing rod tensile strength and flexural strength are), the remarkable advantage of (silicon rubber has unique strong hydrophobic nature) is cleaned in resistance to filth less, overcome the aging life-span problem of conventional macromolecular material simultaneously, many decades can be used safely, it is all new generation product that power system is promoted the use of.
Now retrieving one section of notification number is CN201138588Y Chinese patent document composite cross-arm insulator, the bulb gold utensil of such insulator can be interconnected with ball-and-socket gold utensil and realize superposing of insulator, thus effectively increase creepage distance, but bulb gold utensil easily departs from ball-and-socket gold utensil, cause wire short circuit.
Practical novel content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of composite cross-arm insulator, multiple composite cross-arm insulator mutually connect after stable connection, not easily separated.
For achieving the above object, the utility model provides following technical scheme:
A kind of composite cross-arm insulator, comprise bulb gold utensil, full skirt group and the ball-and-socket gold utensil vertically arranged successively, the chute for bulb gold utensil slippage offered by described ball-and-socket gold utensil, described chute internal fixtion has shell fragment, described shell fragment squeeze bulb gold utensil both sides are fixed, the outer wall of described ball-and-socket gold utensil is fixed with earrings, and described earrings is inserted with band, and described band is wound in the two-port of chute.
By adopting technique scheme, bulb gold utensil enters ball-and-socket gold utensil by chute slippage, it is achieved series connection between two composite cross-arm insulators coordinates, the strong wind area such as in Xinjiang, and wire swings because of wind, and bulb gold utensil easily skids off bulb gold utensil;The head of ball-and-socket gold utensil is stuck in chute to realize Primary Location between the two, extrusion elastic when ball-and-socket gold utensil slips into chute, shell fragment generation deformation is made then to produce a reactive force, these bulb gold utensil both sides are all subject to reactive force, stiction between bulb gold utensil and ball-and-socket gold utensil is increased, then the bulb gold utensil is made to be difficult to skid off ball-and-socket gold utensil, it is to increase the stability that both connect; Band is inserted in earrings, band loop is closed and is wound around at the two ends of chute around ball-and-socket gold utensil, if must by band barrier when bulb gold utensil skids off chute in advance so that bulb gold utensil is difficult to skid off ball-and-socket gold utensil, it is to increase the stability of both connections.
Preferably, described chute is divided into upper slot and lower channel, and the cross section of described lower channel is kidney ellipsoid, and the cross section of its upper slot is rectangle, and the cross-sectional area of upper slot is less than the cross-sectional area of lower channel.
By adopting technique scheme, lower channel is kidney ellipsoid, its two wall is the circular arc of indent, the surface, bulb of bulb gold utensil is circular arc shape, lower channel is convenient to slipping into of bulb gold utensil, and the cross section of upper slot is less so that the bulb and the upper slot card that slip into lower channel connect so that bulb gold utensil is stable with ball-and-socket gold utensil to be connected.
Preferably, the one end of described chute is provided with block, and described block is placed in described upper slot.
By adopting technique scheme, block plays positioning action, make the bulb gold utensil slipping into chute move to block place to stop, and block also has the function preventing bulb gold utensil from departing from chute, one of them slippage outlet of bulb gold utensil is blocked by the iris action of block so that bulb gold utensil is stable with ball-and-socket gold utensil to be connected.
Preferably, the sidewall of described lower channel is provided with projection, and the one side that described projection deviates from described end is connected to shell fragment.
By adopting technique scheme, notch is the opening at the two ends of chute. Block be arranged so that bulb gold utensil and chute are by single notch conducting; When bulb gold utensil slips into chute, shell fragment certainly will be promoted to move towards the notch being provided with block by frictional force, easily cause shell fragment to misplace, making the effect decline of the reactive force of shell fragment, projection and shell fragment, to connecing, stop that shell fragment moves towards block, efficiently solve above-mentioned technical problem
Bulb gold utensil and ball-and-socket gold utensil are stablized be connected.
Preferably, full skirt group is made up of staggered big full skirt and little full skirt.
By adopt technique scheme, big full skirt in order to little full skirt antifouling, which reduce insulator attached dirt amount, also increase creepage spacing simultaneously.
Compared with prior art the utility model has the advantage of: increased the stiction between bulb gold utensil and shell fragment by the shell fragment in chute, and by being wound around of band, two ports of chute are intercepted, effectively prevent bulb gold utensil skid off ball-and-socket gold utensil by cooperatively interacting of above-mentioned two structures.
