Abstract
The utility model provides a bus duct capable of ensuring parallel positioning between conducting bars, which relates to the improvement of the bus duct. The bus duct comprises a strip-shaped shell and multiple conducting bars; the plurality of conducting bars are arranged at intervals in the shell; the bottom surface of the shell is provided with at least two conducting bar spacing brackets; the spacing brackets are sheet-shaped; locating slots corresponding to the number of the conducting bars are arranged in a direction towards the center of the shell; the conducting bars are arranged in the locating slots; and gaps among the inner wall of the shell and the conducting bars are filled with mineral insulated fillers. The bus duct is filled up with modified magnesium oxide, so that the bus duct is greatly improved in insulation performance and can work normally even in an open fire, thereby greatly enhancing the fire resistance. The bus duct is totally closed, so that good waterproof performance can be obtained.
Description
Technical field
The utility model relates to the improvement to bus duct.
Background technology
Along with modernization project constantly develops, the power consumption of all trades and professions is fast to be increased, and traditional cable can not satisfy big electric current conveying system, and bus duct just arises at the historic moment.Bus duct is since coming out, and by air type at first, intensity progressively develops into present compound insulation type, and its insulation mode is in continuous improvement, but receives the restriction of environment for use, is existing defective aspect fire prevention, waterproof, the anti-aging all the time.
Patent Office of State Intellectual Property Office is CN 201868811 U in the notification number of 2010.6.15. bulletin, and the patented technology that name is called fireproof bus duct discloses a kind of fireproof bus duct, and it fills fire resistant infilling then in that some busbars are arranged in the housing at interval.But in the practical application,, be difficult to guarantee the positioned parallel relation between each busbar again because the fire resistant infilling of being filled is the powder shape; Still possibly cause occurring " short " problem.Therefore, in this case, " said conductor each external packets be covered with insulating barrier ".Make the cost of product increase, radiating effect is poor.
The utility model content
The utility model provides a kind of bus duct that can guarantee positioned parallel between the busbar to above problem.
The technical scheme of the utility model is: comprise strip housing and some busbars, said some busbars are arranged in the housing at interval, on said housing bottom surface, are provided with at least two busbar spacers; Said spacer is a sheet, is provided with the location notch consistent with busbar quantity towards the housing center position, and said busbar is arranged in the said location notch; Gap filling mineral insulating packing between inner walls and busbar.
Said spacer is arranged on the position of the interior two ends of said housing near housing end plug.
Said housing comprises top cover, on the bottom surface of said top cover, also be provided with said housing in the spacer of spacer position consistency, make said busbar be positioned between housing bottom surface spacer and the housing top cover spacer.
The utility model has changed traditional insulation mode, and through with tamping modified oxidized magnesium in the groove, the insulation property of bus duct will be greatly improved like this, and since magnesian fusing point than higher, even also can operate as normal under naked light, fire line strengthens greatly.The utility model adopts totally enclosed type, and water resistance is fine.Comprehensive, this bus duct can avoid receiving the influence of ambient conditions, has given play to good transmission of electricity effect.The most key is can guarantee mutual parallel accuracy when mounted between each busbar (conductor) in the utility model, the unbalanced short problem that causes of pressure when avoiding filling filler; In addition, with respect to prior art, reduced the coated insulation layer, lead row directly contact with the mineral insulation filler, and then can promote radiating effect.

Embodiment
The bus duct of the utility model shown in Fig. 1-4, comprises strip housing 1 and some busbars 4, and said some busbars 4 are arranged in the housing 1 at interval, on said housing 1 bottom surface, are provided with at least two busbar spacers 5; Said spacer 5 is a sheet, is provided with and the consistent location notch of busbar 4 quantity towards housing 1 center position, and said busbar 4 is arranged in the said location notch; Gap filling mineral insulating packing 6 between housing 2 inwalls and busbar 4.
Said spacer 5 is arranged on the position of said housing 1 interior two ends near housing end plug 3.Longer like bus duct, then can set up a spacer at the middle part.
Said housing comprises top cover 2, on the bottom surface of said top cover 2, also be provided with said housing 1 in the spacer of spacer 5 position consistency, make said busbar 4 be positioned between housing 1 bottom surface spacer and the housing top cover spacer.Make that the location steadiness of busbar 4 is better.
