Abstract

The invention discloses a bus duct. The bus duct includes a shell, the shell is internally provided with a copper bar installing cavity formed by a groove A (3) and a groove B (4), the copper bar installing cavity is internally provided with copper bars (5), and a plurality of air exhaust grooves (8) are arranged on inner walls of the groove A (3) and the groove B (4). The bus duct provided by the invention has the advantages of simple structure and ingenious design; by adoption of the bus duct, air in the copper bars can be conveniently discharged, so that the copper bars can be attached closely; at the same time, a packaging technology is simplified, so that the size is relatively small, sealing performance is improved, and water and dust are prevented from entering into the bus duct; in addition, a heat dissipation effect is also improved, thereby enabling power transmission to be relatively good; and in a carrying process, influence of vibration on the bus duct is also effectively prevented.

Description

A kind of bus duct

Technical field

The present invention relates to a kind of power equipment, particularly a kind of bus duct.

Background technology

In order to ensure the needs of high-current low-voltage transmission line, power distribution design all adopts bus duct mains system, and the mains system of bus duct has been widely applied in engineering.

The application for a patent for invention that name is called " energy-saving bus slot " is disclosed in CN101800405A, this bus duct with two symmetrically arranged bus side plates, bus cover plate for overall support, side plate fin is provided with at the lateral surface of two bus side plates, cover plate is positioned at the lateral surface of two flangings of two bus side plates, and by securing member, bus side plate and cover plate are connected into an entirety, in the region that bus side plate and cover plate enclose, form a cross section is the space of rectangle, be provided with insulating barrier at the medial surface of bus side plate, bus-bars conductor is between insulating barrier.

The parts such as disclose the application for a patent for invention that name is called " fireproof bus duct " in CN102231503A, it comprises housing cover, connecting bolt, conducting copper, fire-resistant wrapping tape and layer insulation, housing side plate, cross-over block, fastening bolt form.

The application for a patent for invention that name is called " bus duct " is disclosed in CN104682300A, it comprises bus, dress head, cover plate and side plate, described cover plate comprises bottom panel and side panel, the both sides of described bottom panel are connected to side panel, the junction of described bottom panel and described side panel is formed with groove, the top of described bottom panel is provided with some waterline grooves for draining and apopore, described waterline groove is communicated with described apopore, the bottom of described bottom panel is provided with the fin for separating phase line and ground wire, described bottom panel is provided with the bar hole that the some dress heads for connection bus pass through, described side plate is " recessed " type, the inside bottom of described side plate is provided with some radiating grooves.

Although the bus duct in above-mentioned patent application all can realize the needs of high-current low-voltage transmission line, but still there is following shortcoming in the bus duct in above-mentioned patent application: 1. owing to being be made up of two side plates and two side cover plates, when assembling, very inconvenient, volume is also larger; 2. because copper bar can generate heat in conducting process, and side plate there is no radiator structure, cause the radiating effect of bus duct poor, the ability of transferring electric power reduces; 3., owing to adopting two side plates and two side cover plates to form integral bus bar groove, have gap between side plate and side plate, sealing effectiveness is poor, and degree of protection is lower, easily causes water and dust to enter gap; 4., in copper bar assembling process, owing to there is air between copper bar and copper bar, after causing side plate to be installed, there is gap, cannot fit tightly, easily make its water and dust enter gap.

Summary of the invention

Object of the present invention is just to provide a kind of bus duct effectively can discharging air between copper bar.

The object of the invention is by such technical scheme realize, a kind of bus duct, described bus duct comprises housing, the copper installation chamber be made up of groove A and groove B is provided with in described housing, in described copper installation chamber, be provided with copper bar, the inwall of described groove A and groove B is provided with multiple air discharge duct.

By air discharge duct, can make to discharge the air between copper bar and copper bar, when making to connect, laminating more tight,

Wherein, described housing comprises symmetrically arranged housing A and housing B, and described groove A and groove B is separately positioned on the obverse middle part of described housing A and housing B.

In order to damping, be respectively arranged with silicagel pad in the upper surface in described copper installation chamber and lower surface.

In order to improve radiating effect, the outer wall of described housing A and housing B is all horizontally disposed with fin.

In order to anti-sealing and dust enter, the composition surface of the upper and lower of described housing A and the upper and lower of housing B is provided with seal gasket, the two ends of the fin on described housing A and housing B outer wall are provided with sealing shroud.

More firm in order to make to connect, be respectively arranged with connector side plate at the two ends of described housing A two ends and housing B, the outer wall of described connector side plate is provided with packing ring installing hole, outside two of described packing ring installing hole, be provided with screw attachment holes.

In order to improve heat radiation, on the outer wall of described connector side plate, perpendicular connectors side plate has been horizontally disposed with fin.

Owing to have employed technique scheme, the present invention have structure simple, design advantage cleverly, adopt it not only can discharge space in copper bar easily, make to fit between copper bar and copper bar more tight, meanwhile, also simplify packaging technology, make volume less, improve good seal performance, prevent water and dust to enter in bus duct, and, also improve radiating effect, make electric power transfer better, in handling process, also effectively prevent the impact of vibrations on bus duct.
