Description

Technical Field

[0001] The present invention relates to the technical field of power transmission and distribution, and in particular to an insulating partition and a bus duct connector having the insulating partition. Background Art

[0002] Bus ducts, a closed metal structure made of copper and aluminum busbars, are used to distribute high power to various components in a distributed system. They are increasingly replacing wires and cables in indoor low-voltage power transmission trunk projects.

[0003] Bus duct connectors are widely used in key projects such as power transmission trunk lines for firefighting equipment, for example in hotels, airports, subways and other places. Therefore, the waterproof ability, heat dissipation ability, and safety and stability of bus duct connector products are particularly important. The connector between two sets of bus ducts usually generates a lot of heat, and the heat generated cannot be dissipated in time, resulting in low heat dissipation performance, which is likely to bring fire safety hazards. Therefore, its heat dissipation problem has always been a major problem that has plagued R&D personnel.

[0004] Existing insulating partitions used in bus duct connectors are mostly made of dimethyl carbonate (DMC) or sheet molding compound (SMC), which have poor heat dissipation effects and still cannot dissipate the heat in the bus duct connector in a timely manner. Summary of the Invention

[0005] The object of the present invention is to provide an insulating partition having both insulating and heat dissipating properties and a bus duct connector having the insulating partition in view of the existing technical status.

[0012] Preferably, the insulating sleeve is made of polyester, and the insulating gasket and edge strip are both made of engineering plastics.

[0013] A busbar duct connector with insulating partitions is characterized in that the busbar duct connector includes two side plates and several insulating partition groups and conductive connecting copper plates located between the two side plates, and the side plates, insulating partition groups and conductive connecting copper plates are assembled together by insulating bolts.

DETAILED DESCRIPTION

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0033] See also Figures 1-10As shown, the present invention discloses an insulating partition, including a base 1, the base 1 is made of aluminum alloy, and a plurality of mounting holes 2 are evenly distributed along the length direction of the base 1. The mounting holes 2 are arranged at intervals, and slots 3 are opened at both ends of the width of the base 1. The slots 3 pass through both ends of the length direction of the base 1. The outer surface of the base 1 is provided with an insulating sleeve 4 adapted to the base 1, and side strips 5 embedded in the slots 3 are provided on both sides of the base 1. The side strips 5 have plug-in ends 6 that match the slots 3.

[0034] The base 1 made of aluminum alloy is used to quickly dissipate heat and has heat dissipation performance. An insulating sleeve 4 is set on the outer surface of the base 1 and fixed by a side strip 5 to ensure the insulation performance of the insulating partition.

[0035] As a preferred embodiment, the mounting hole 2 is a through hole, and the base 1 is provided with a groove 9 for mounting the insulating gasket 8 on the side end surface of the mounting hole 2 . The groove 9 is circular and communicates with the mounting hole 2 .

[0036] As a preferred embodiment, the insulating gasket 8 includes a base plate 81 , which fits the inner wall of the groove 9 . A boss 82 is provided at the center of the base plate 81 , and the boss 82 is a hollow ring.

[0037] As a preferred embodiment, the slot 3 is a mushroom-shaped empty slot, which includes two parallel and horizontally extending planes 31, a connecting surface 32 that arches outward at one end of the two planes 31 close to the mounting hole 2, and a circular surface 33 connected between the two connecting surfaces 32.

[0038] Furthermore, the connecting surface 32 and the plane 31 form a contracted narrow opening, and both the connecting surface 32 and the circular surface 33 are arc structures.

[0039] As a preferred embodiment, the plug end 6 is a mushroom-shaped convex body, and the plug end 6 includes a horizontal section 61 , step surfaces 62 extending horizontally outward along both ends of the horizontal section 61 , and a convex circle 63 connecting the two step surfaces 62 .

[0040] As a preferred embodiment, the insulating sleeve 4 is made of polyester, and the insulating spacer 8 and the edge strip 5 are both made of engineering plastics. The polyester and engineering plastics used are all commercially available and well-known products.

[0041] The insulating sleeve 4 used in this application is open at both ends and connected at both ends, and is used to be sleeved on the outer surface of the base 1. The insulating sleeve 4 is abutted against the inside of the slot 3 through the cooperation of the side strip 5 and the slot 3, and the side strip 5 is used to achieve the effect of internal support and anti-slip, so that the insulating sleeve 4 is tightly connected to the base 1.

[0042] During the specific installation, first fix the chassis 81 of the insulating gasket 8 on the inner wall of the groove 9, so that the boss 82 faces the outside away from the base 1, and then put the insulating sleeve 4 on the outer surface of the base 1, the insulating sleeve 4 covers the chassis 81, and the boss 82 is exposed outside the insulating sleeve 4, then insert the plug-in end 6 of the edge strip 5 into the slot 3, so that the convex circle 63 fits the circular surface 33 of the slot 3, and the step surface 62 presses against the connecting surface 32. The narrow opening prevents the edge strip 5 from falling off and thus prevents the insulating sleeve 4 from detaching from the base 1, and the horizontal section 61 fits the plane 31.

[0043] The edge strip 5 in the present application also has a guide surface 7, which is inclined in a direction away from the base 1, and a conductive connecting copper plate 12 is fixedly installed on one side of the insulating partition close to the guide surface 7.

[0044] like Figure 11-14 As shown, a bus duct connector with insulating partitions includes two side panels 10, a plurality of insulating partition groups and a conductive connecting copper plate 12 located between the two side panels 10, and the side panels 10, the insulating partition groups, and the conductive connecting copper plates 12 are assembled together by insulating bolts 13. The use of the insulating partitions of the present application ensures the insulation and heat dissipation performance of the bus duct connector and reduces safety hazards.

[0045] As a preferred embodiment, the insulating partition group consists of two side insulating partitions 14 respectively attached to the side plates 10 and several middle insulating partitions 15 distributed side by side between the two side insulating partitions 14. The inner side of the side insulating partition 14 is provided with a conductive connecting copper plate 12, and both sides of the middle insulating partition 15 are provided with a conductive connecting copper plate 12.

[0046] The difference between the edge insulating partition 14 and the middle insulating partition 15 is that the edge insulating partition 14 is used to be close to the side plate 10, and the edge insulating partition 14 is only provided with a groove 9 on one side end face of the base 1 located at the mounting hole 2, that is, one mounting hole 2 is only installed with one insulating gasket 8, and the side strip 5 is only provided with a guide surface 7 on one side end face, and the groove 9 is on the same side as the guide surface 7.

[0047] The middle insulating partition 15 is arranged in the middle of the connector. The middle insulating partition 15 is provided with grooves 9 on both side end surfaces of the base 1 located at the mounting hole 2, that is, insulating gaskets 8 are installed above and below a mounting hole 2, and guide surfaces 7 are provided on both side end surfaces of the side strip 5.

[0048] As a preferred embodiment, a gap 16 is maintained between the conductive connecting copper plates 12 of two adjacent insulating spacers in the insulating spacer group, and the connecting end of the conductor 17 is inserted into the gap 16 .

[0049] A shielding frame 19 is provided on the side of the busbar unit 18. The shielding frame 19 is in a U shape. The connection end of the conductor 17 in the busbar unit 18 is located inside the shielding frame 19. Two stop bars 11 are arranged in parallel on the inner sides of the two side plates 10 of the connector. The two stop bars 11 are arranged along the height direction of the side plate 10. The distance between the two stop bars 11 is greater than the diameter of the mounting hole 2. The shielding frames 19 of the two busbar units 18 respectively abut against the two stop bars 11, playing a role in positioning and limiting.

[0050] When two busbar units 18 need to be connected, the connection end is inserted into the spacing 16 so that both sides of the conductor 17 are in contact with the conductive connection copper plate 12. Then, the insulating bolts 13 are sequentially passed through the side plate 10, the edge insulating partition 14, the conductive connection copper plate 12, and the middle insulating partition 15, thereby assembling the side plate 10, the insulating partition group, and the conductive connection copper plate 12 together. In order to prevent the busbar connector from being exposed, cover plates 20 are respectively provided above and below the connector to block direct contact between the outside world and the connector and improve the safety performance.

[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
