Disclosed in CN102231503A, name is called the application for a patent for invention of " fireproof bus duct ", and it includes the parts compositions such as housing cover, connecting bolt, conducting copper, fire-resistant wrapping tape and layer insulation, housing side plate, cross-over block, fastening bolt。
Disclosed in CN104682300A, name is called the application for a patent for invention of " bus duct ", it includes bus, dress head, cover plate and side plate, described cover plate includes 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 the some waterline grooves for draining and apopore, described waterline groove connects 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 passed through for the some dress heads connecting bus, 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 is all capable of the needs of high-current low-voltage transmission line of electricity, but, the bus duct in above-mentioned patent application yet suffers from following shortcoming: 1. owing to being be made up of two side plates and two side cover plates, when assembling, extremely inconvenient, volume is also bigger；2. owing to copper bar can generate heat in conducting process, and there is no radiator structure on side plate, cause that the radiating effect of bus duct is poor, the ability of transmission electric power reduces；3. owing to adopting two side plates and two side cover plates to constitute integral bus bar groove, having gap between side plate and side plate, sealing effectiveness is poor, and degree of protection is relatively low, it is easy to cause that water and dust enter gap；4. in copper bar assembling process, owing to having air between copper bar and copper bar, cause that side plate has gap after installing, it is impossible to fit tightly, it is easy to make its water and dust enter gap。
Utility model content
