Description
Technical field
The utility model relates to electric cable fitting, more particularly, relates to the splicing bus connector of a kind of 2500A of being applicable to and above large electric current.
Background technology
In the application process of Inflatable cabinet switch equipment, the connecting method of cabinet connects the design of insulating part and the control of installation quality, is the key factor of product safety operation.The connecting method of switch cubicle generally is divided into side splicing or splicing at the bottom of the cabinet Top Tank at present; Splicing bus is flexible and changeable with its splicing distance at the bottom of the cabinet Top Tank, and stable high obtains using more widely in switch cubicle.
More and more higher to the through-current capability requirement of switch cubicle at present, and the general through-current capacity of splicing bus is all below 1250A, the through-current capability of therefore existing bus can not satisfy the growth requirement of switch cubicle far away, also can not meet a lot of project demands simultaneously.In order to reach the purpose of the large current delivery of bus 2500A, the bus tie that existing through-flow power is 1250A can only be realized by the mode of enumerating splicing.As shown in Figure 1, thereby with two bus tie that assembles of the cover stacks that realize electric current in parallel, but due to the restriction of 1250A sleeve pipe, now only have and utilize two sleeve pipe inlet wires could realize the large electric current of 2500A.This kind connection scheme not only makes the inlet wire scheme complicated, and it is large to take up room; Simultaneously, the bus tie consumption is many, and cost is increased, and the more contact interfaces of contained sample are more, cause electric stability poorer; And bus tie enumerate splicing, the conductor gold utensil connects increases the consumption that will inevitably cause electric current.
And present stage existing 2500A bus, in order to guarantee through-current capacity, the gold utensil volume of manufacturing is larger, thereby causes the bus tie overall dimensions larger, takes up room, and increases cost, does not meet simultaneously the requirement of present economizing type, compact switch cabinet.
Therefore, a kind of novel through-current capacity of development and Design is large, insulation property are high, the splicing size flexibly, spliced bus tie at the bottom of the cabinet top of miniaturization densification or cabinet, be one of the key that improves the technical quality level of cabinet type Cubicle Gas-Insulated Switchgear.
The utility model content
The purpose of this utility model is to overcome shortcoming of the prior art with not enough, provide a kind of can the through-current capacity of splicing be large at the bottom of switch cabinet top or cabinet, insulation property are high, the splicing size flexibly, the bus tie of miniaturization densification.This bus tie can be arranged on top or the bottom of switch cubicle, its simple installation, stable performance; And can be equipped with according to the distance that the switch cubicle splicing requires the splicing bus of corresponding length; This connector has the 2500A through-current capability simultaneously, can realize the requirement of the large electric current of present switchgear.
In order to achieve the above object, the utility model is achieved by following technical proposals: connected to form successively by a connector, a d intermediate connector and another connector, connect and to realize by splicing bus, and d=n-2 wherein, n is for needing to splice switch cubicle quantity;
Described each connector comprises rubber sleeve one and is arranged at conduction gold utensil one in rubber sleeve one, and conduction gold utensil one comprises that two identical conduction fixture blocks prop up piece with being clipped in two conductions in the middle of the conduction fixture block, and two conduction fixture block mirror images arrange; Described intermediate connector comprises rubber sleeve two and is arranged on conduction gold utensil two in rubber sleeve two, and conduction gold utensil two comprises two identical conduction fixture blocks.
