Description
Technical field
The utility model relates to contact cabinet technical field, specifically a kind of low voltage liaison net cabinet.
Background technology
In order to improve reliability and the flexibility of power supply, usually low-voltage bus bar is divided into several sections, by contact cabinet, bus is coupled together, low voltage liaison net cabinet is widely used in the various occasions of distribution, the designing and making of usual contact cabinet bus is, the upper side connecting plate of section breaker is directly connected on one section of bus rod by copper busbar, the lower side connecting plate of section breaker extends downward cabinet bottom by copper busbar, be connected on the horizontal bus of three-phase of cabinet bottom setting, then three-phase vertical bus bar is set again on the horizontal bus of three-phase, upwards translate on other one section of bus rod in the side of contact cabinet, not only consume a large amount of copper bars, it is large that bus makes workload, the corresponding increase of cabinet width, and cause the faying surface of copper busbar in cabinet many, add contact resistance, add the caloric value of copper bar, there is potential safety hazard.
Summary of the invention
The technical problem that the utility model mainly solves is to provide one can save copper busbar, reduces the low voltage liaison net cabinet of potential safety hazard.
The technical solution adopted in the utility model is:
A kind of low voltage liaison net cabinet, comprises cabinet, also comprises cabinet top and runs through bus frame brace summer before and after cabinet, described bus frame brace summer is fixedly connected with the bus frame that two fore-and-aft directions stagger completely; Cabinet bottom is fixed with section breaker, and described section breaker top is fixed with side connecting plate, and described section breaker bottom is fixed with lower side connecting plate; Cabinet front portion is provided with N number of I section copper busbar side by side that upper end connects the upper side connecting plate of anterior bus frame lower end connection, and cabinet rear portion is provided with N number of II section copper busbar side by side that upper end connects the lower side connecting plate of anterior bus frame lower end connection; Be fixedly connected with insulator in the middle part of every root copper busbar, insulator is fixed on two insulator brace summers being positioned at and running through in the middle part of cabinet before and after cabinet.
Described low voltage liaison net cabinet, is characterized in that: described copper busbar quantity N is 3, and I section copper busbar and II section copper busbar comprise A phase copper busbar respectively, B phase copper busbar and C phase copper busbar.
Described low voltage liaison net cabinet, is characterized in that: described upper side connecting plate and described lower side connecting plate material therefor are copper.
Described low voltage liaison net cabinet, is characterized in that: described insulator material therefor is rubber.
The beneficial effect that the technical scheme that the utility model provides is brought is: leave enough electric clearances between two sections of bus frames, all insulator is provided with in the middle of each phase copper busbar, carry out reinforcement to copper busbar on the one hand to support, can strengthen copper busbar resists electrodynamic ability on the other hand, electric property is more safe and reliable, greatly save copper busbar consumption, not only save a large amount of manpowers, and avoid the waste of resource.
