Abstract

The utility model discloses an improved insulating busbar channel, which is used for a low-voltage distribution system. The widths among the conductive strips on the sections of the busbar channel are equal on both ends; the tops on the two ends of each conductive strip are respectively provided with one to six opening holes; the other component which can form the utility model is a butt connecting device which is composed of a connecting conductive strip, an insulating board, and a fastening bolt. When the improved insulating busbar channel is used, the sections of the two busbar channels are arranged in one butt connecting device; the fastening bolt is screwed, and accordingly, the section pair of the two busbar grooves are switched on. The utility model has the advantages of simple structure, convenient processing, better heat radiating performance, small size, less material consumption, and light weight.

Description

Insulating busbar channel

The utility model relates to a kind of improved isolated bus groove that is used for low-voltage distribution system.

Existing mutual-inserting type bus duct, must be at the two ends of every bus duct, socket and interface arrangement are set respectively, one or several circular holes are arranged on each socket, the interface arrangement, elder generation inserts the socket of a bus duct in the interface of another bus duct during use, insert circular hole with bolt again, tighten fixing.This mutual-inserting type bus duct mainly contains following deficiency: 1, complex structure, production cost height.2, socket and interface arrangement contact area are less, and thermal diffusivity is relatively poor.3, volume is big, materials are many, Heavy Weight.

The method that CN2044386U bridge-type plug-board bus bar groove adopts is to remove the fixedly socket and the interface arrangement at mutual-inserting type bus duct two ends, and independently bridge is slotting to set up one, can solve the relatively poor deficiency of complex structure, thermal diffusivity that the mutual-inserting type bus duct exists.But, bridge needs to form with bridge and spring contact because inserting, and, between spring contact during use on every busbar and other root busbar certain electric clearance need be arranged, therefore, increased the width and the copper contact materials of bus duct, be difficult to solve that mutual-inserting type bus duct volume is big, materials are many, the deficiency of Heavy Weight.

The purpose of this utility model be to provide a kind of both simple in structure, easy to process, thermal diffusivity is better, volume is little again, materials are few, lightweight counterpart formula isolated bus groove.

The purpose of this utility model is achieved in that socket and the interface arrangement of removing mutual-inserting type bus duct two ends, even the width two ends that the bus duct joint is gone up between the busbar equate that one to six open pore is arranged at top, every busbar two ends.Constituting another parts of the present utility model is counterpart jockeys, and it is made up of insulation board, connection busbar, fastening bolt.Every insulation board is provided with one to six hole; Every connects busbar and is provided with one to six hole; Every cover fastening bolt has insulating barrier with being connected between busbar, the busbar.The number in hole or the number that is connected hole on the busbar equate that the number that saves the arbitrary end opening of last every busbar hole with a bus duct equates on the tricks that counterpart jockey tightens bolt and the every insulation board.The quantity that the quantity of a counterpart jockey upper insulation plate goes up busbar than a bus duct joint is Duoed one.Width between the other neutral gear of the connection busbar place equates with the width between the busbar.During use, two bus duct joints to going in the counterpart jockey, are tightened fastening bolt, thereby make two bus duct joints connecting.

The utility model can be removed the socket and the interface arrangement of mutual-inserting type bus duct, and not need copper contact, making leaf spring, the closing-up of bridge-type plug-board bus bar groove, so simple in structure, easy to process because of adopting the counterpart jockey; During use, the contact area that connects busbar in busbar and the bus duct joint in the counterpart jockey can be bigger, so thermal diffusivity is better; In addition; because the insulation protection effect only just can be played equally with five insulation boards in the junction (is example with the three-phase four-wire system bus duct) at two bus duct joints; lack than two junctions of mutual-inserting type bus duct and to use three insulation boards; and do not need bridge-type plug-board bus bar groove between the spring contact on the every busbar and other root busbar, certain electric clearance to be arranged like that; so; can make the reduced width of whole piece bus duct joint, volume, materials, weight all can correspondingly reduce.

Concrete structure of the present utility model is provided by following examples and accompanying drawing:

Fig. 1 is a counterpart jockey side half sectional view.

Fig. 2 is for connecting the busbar front view.

Fig. 3 is three-phase four-wire system bus duct joint structural representation.

Fig. 4 is a busbar top structure schematic diagram.

Fig. 5 is three-phase four-wire system bus duct joint and counterpart jockey horizontal plane connection status cutaway view.

Fig. 6 is the positive connection status figure of three-phase four-wire system bus duct joint and counterpart jockey.

Below in conjunction with details and the operating position of accompanying drawing detailed description according to the concrete counterpart formula isolated bus groove that the utility model proposes.

Every connects and to have insulation board (2) to isolate between the busbar (1), and the hole (4) that fastening bolt (3) is inserted on the insulation board (2) connects with hole (5) on being connected busbar (1), forms a counterpart jockey.Every cover fastening bolt (3) be connected between busbar (1), the busbar (8), have and insulation board (2) for one, or be split or not only promising one, but also the insulating barrier (6) of promising split.Because of the width (A) that connects between the other neutral gear place of busbar (1) (7) equates with width (B) between the busbar (8), article two, the bus duct joint can be to going in the counterpart jockey, busbar (8) be connected busbar (1) plane contact, open pore (9) and insulating barrier (6) contacts side surfaces, tighten fastening bolt (3), thereby make two bus duct joints connecting.
