Abstract
The utility model provides a 17.5 kilovolt full-casting medium-voltage busbar, which comprises a three-phase conductor and an insulator, wherein the three-phase conductor is located inside the insulator roughly in parallel, the insulator is fully cast, a plurality of rectangular radiation holes which are 940 mm long and 120 mm wide are arranged between adjacent phases of the three-phase conductor, and semicircular radiation holes which are 80 mm in diameter are arranged at both ends of the three-phase conductor. The 17.5 kilovolt full-casting medium-voltage busbar is simple in structure; the spacing between the rectangular radiation holes increases to 160mm, the radiation volume is increased, and the thermal stability and the dynamic stability endurance are improved; the radiation volume is increased to above 300%, copper consumption is reduced and the energy-saving effect is more excellent; and the overall casting material consumption is reduced so that the total weight of components can be relatively reduced, and construction and hanger mounting are more time-saving and labor-saving.
Description
Technical field
The utility model relates to electric wire, cable technology field, particularly presses bus in a kind of 175 kilovolts of full cast.
Background technology
Present 10 ~ kv pours into a mould between the bus three-phase conductor fully entirely without heat abstractor (be three-phase conductor watered cast from the large square type mould material), or heat dissipation design is not good, cause three-phase temperature rise deviation quite large, therefore (800A ~ 1000A) for example when small electric flows, because caloric value Yet-have is little, still rational, but when surpassing this capacity, because the relative caloric value of electric current is also large greatly, its radiating effect is namely had a greatly reduced quality. and the use amount of copper becomes very inefficent with respect to the output electric current, and resources untilization is produced greatly waste.
The utility model content
In view of this, the technical problem that the utility model solves is: provide in a kind of 175 kilovolts of full cast and press bus, it is simple in structure, and the heat radiation volume is promoted to more than 250%, makes copper consumption and energy-conservationly more puts in place.
For solving the problems of the technologies described above, the technical solution of the utility model specifically is achieved in that
The utility model provides in a kind of 175 kilovolts of full cast and has pressed bus, it comprises three-phase conductor and insulator, it is inner that described three-phase conductor almost parallel ground is positioned at described insulator, described insulator is poured into a mould formation entirely, described three-phase conductor have between phase and phase a plurality of length be 440 millimeters, wide be 120 millimeters rectangle heat radiation hole, and to have diameter be 80 millimeters semicircle heat radiation hole at described three-phase conductor two ends.
Preferably, described rectangle heat radiation hole along the spacing between phase and phase in 60 millimeters to 120 millimeters scope.
Preferably, described three-phase conductor is the identical copper conductor in cross section.
Press bus structure simple in 175 kilovolts of full cast of the present utility model, the alternate spacing of square type heat radiation hole is increased to 160mm, has strengthened the heat radiation volume, and has promoted the thermally-stabilised and moving endurance of stablizing; Simultaneously, the heat radiation volume is promoted to more than 250%, makes copper consumption and energy-conservationly more puts in place; In addition, integrated poured consumption reduces, and makes assembly overall weight relative reduce, and construction is more time saving and energy saving with suspension and support.
