Abstract
The utility model relates to a composite insulating cross arm for oil field power transmission cable, which solves the problem that poor corrosion resistance and insulation of cross arms bring trip circuit breakage in the raining season when the distribution cable is easy to be stricken by lightning. The utility model is characterized in that the cross arm (1) is a glass steel square pipe, both ends of which are opened with an insulator connecting hole (6); the cross arm (1) is in the middle and fixed to a wire pole (3) with a U-shaped galvanized bolt (4) through a glass steel cushion block (2). with long service life, the cross arm is characterized in corrosion resistance and good insulating performance and has the capability of lightning proof in raining seasons, preventing trip and circuit breakage, not affecting the oil pumps to work.
Description
Technical field:
The utility model relates to the used a kind of cross-arm of oil field transmission line of electricity, belongs to the compound insulation type cross-arm.
Background technology:
Great majority utilize oil pumper and electric submersible pump to pump in the oil extraction process at present, and too busy to get away distribution line is powered, and are higher to the stability requirement of power supply.And the line density of existing distribution network is big, and the circuit in peripheral oil field is in the multiple district of thunderbolt mostly, the galvanizing angle steel cross-arm that generally adopts for the present distribution line electric hoist of arranging in pairs or groups, because corrosion resistance, the insulating properties of this angle steel are relatively poor, its thunder and lightning all-wave impacts 50%, and flashover voltage is 80KV, voltage when power frequency is drenched with rain occur creepage is 32KV, revealing distance is 185mm, thunderstorm season distribution line be easy to be struck by lightning and trip and open circuit, influence oil pumper work.
Summary of the invention:
For overcome existing cross-arm corrosion resistance, insulating properties is relatively poor and cause thunderstorm season distribution line be easy to be struck by lightning and the problem that trips and open circuit, the utility model provides a kind of compound insulation type cross-arm, this cross-arm resistance to corrosion is strong and have good weather resisteant, is fit to promote.
Technical solution adopted in the utility model is: this compound insulation type cross-arm comprises electric pole and cross-arm, and cross-arm is the glass fiber reinforced plastic square tube and has the porcelain vase connecting hole at two ends that cross-arm is fixed on the electric pole with U type galvanized bolt by the glass fiber reinforced plastic cushion block between two parties.
The beneficial effects of the utility model are: because this cross-arm has adopted glass reinforced plastic pipe corrosion-resistant, that insulated type is good, make the transmission line of electricity of arranging in pairs or groups have in anti-ability of being struck by lightning of thunderstorm season by this cross-arm, avoid tripping and opening circuit, do not influence oil pumper work, long service life.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
In Fig. 1, this compound insulation type cross-arm comprises electric pole 3 and cross-arm 1, cross-arm 1 adopts corrosion-resistant, the glass fiber reinforced plastic square tube that insulated type is good and have porcelain vase connecting hole 6 at two ends, purpose can be installed porcelain vase, make the transmission of electricity electric wire be contained on the porcelain vase, cross-arm 1 is fixed on the electric pole 3 by glass fiber reinforced plastic cushion block 2 usefulness U type galvanized bolts 4 between two parties, avoid 1 of electric pole 3 and cross-arm that the space is arranged and make cross-arm 1 landing from the electric pole 3, make simultaneously and open circuit having avoided thunderbolt thunderstorm season, improved the dielectric level of distribution line greatly, intensity is also high, good toughness can extensive use on the distribution line of oil field.
