Abstract
The utility model provides insulated glass fiber reinforced plastic cross bars which are used for making a tower head in an aerial circuit. The utility model is characterized in that at least two cross bar split phases are arranged in the cross bars. Each cross bar split phase is connected with the other by a connector. Each cross bar split phase is made of glass-reinforced plastic material. Insulators are arranged on the cross bars. The utility model has the advantages of portability, corrosion prevention, favorable lightning impulse prevention and contamination resistance, and easy installation and repair. The utility model can heighten the effective height of the pole tower and simplify the structure of the tower head, so that the labor intensity of the workers' high-lift operation can be improved. The utility model can not only be used in a new circuit, but also can be used in an old circuit. The utility model especially is adapted to be popularized and used in the circuits in which the component reconstructed by pressure boosting is susceptible to be eroded and thunder and lightning acts frequently.
Description
The utility model relates to a kind of glass fibre reinforced plastic insulating cross-arm that is used for the making tower head of overhead wire.
General timber and the various section steel manufacture tower head structures of adopting of existing overhead wire structure more, this uses on new line is rational, but in the time of on old circuit, need being upgraded to the high voltage operation by low-voltage, just must remove original shaft tower and all facilities, set up a high-tension new line again.
In view of above reason, the purpose of this utility model is not only to can be used for new line in order to provide a kind of, and can be used for glass fibre reinforced plastic insulating cross-arm old circuit, easy for installation, safety, good insulation preformance.
Have two cross-arm phase-splittings in the utility model at least, each cross-arm phase-splitting connects by connector each other, and each cross-arm phase-splitting adopts glass-reinforced plastic material to make, and insulator (referring to Fig. 1, Fig. 2, Fig. 3) is arranged on cross-arm.
Cross-arm phase-splitting useable glass steel in the utility model is made dihedral, flute profile, rectangle etc., can form the π type during connection line bar type tower head structure, go up structures such as font, triangular form, bird bone type, each cross-arm divides the alternate connector that adopts to connect, and connect into integral body with anchor ear, connector with the electric pole junction surface, be the aerial high voltage power transmission shaft tower.Also can utilize the facility of former low-voltage circuit, need not take over the land for use, need not change electric pole, adopt the utility model cross-arm, use a spot of insulator, just former low-voltage circuit can be become high-tension line.
The utility model is light, and is corrosion-resistant, anti-lightning impulse performance, anti-good, the good insulating of filthy performance, for condition has been created in the miniaturization of tower head insulation system, installation and maintenance are easy, can improve the effective height of shaft tower and simplify the tower head structure, improved the labour intensity of workman's work high above the ground simultaneously.The scope of application is wide, not only can be used for new line, and can be used for old circuit, is particularly suitable for promoting the use of on the circuit perishable at the boosting and transformation member, that lightening activity frequent, filth is seriously regional.The expense of setting up is low, needs 200,000 yuan approximately as newly setting up one kilometer 110KV transmission line of electricity, is that the 110KV circuit only needs 100,000 nothings with one kilometer 35KV circuit of the utility model cross-arm boosting and transformation, can save the expense of half.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1: the rigging position figure of the utility model on π type forthright bar type.
Fig. 2: the rigging position figure of the utility model on bird bone type forthright single pole type.
Fig. 3: the rigging position figure of the utility model on last font forthright single pole type.
Embodiment 1:
Fig. 1 has provided embodiment 1 figure of the present utility model.Cross-arm phase-splitting the 2,3,4,5, the 6th in the cross-arm 1 among the figure connects by bolt, and three bar insulation 7 evenly are housed on it.Each cross-arm phase-splitting adopts anchor ear 9 to be connected and to have formed π type forthright bar type structure with electric pole with bolt with the junction surface of electric pole 8.
Embodiment 2:
Fig. 2 has provided embodiment 2 figure of the present utility model.Cross-arm phase-splitting the 11, the 12nd among the figure in the cross-arm 10 connects by bolt 13.Three bar insulation 14 are housed on it.Each cross-arm phase-splitting adopts anchor ear 16,17 to be connected and to have formed bird bone type forthright single pole type structure with bolt and electric pole 15 with the junction surface of electric pole 15.
Embodiment 3:
Fig. 3 has provided embodiment 3 figure of the present utility model.Cross-arm phase-splitting 19,20,21,22,23 among the figure in the cross-arm 18 connects by bolt, and 3 bar insulation 24 are wherein arranged.Each cross-arm phase-splitting adopts anchor ear 25,26,27 and bolt and electric pole 28 to be connected and to have formed last font forthright single pole type structure respectively with the junction surface of electric pole 28.
More than cross-arm phase-splitting among each embodiment all adopt glass fiber reinforced plastic to make.Its shape of cross section can be angle type, grooved, square type.
