A kind of novel bus duct
Technical field
This utility model relates to bus duct field, refers in particular to a kind of novel bus duct.
Background technology
In order to meet the needs of the high-current low-voltage transmission line of electricity in industry, civil engineering construction,
Power distribution design all uses bus duct mains system, recently as electric line capacity
Continuing to increase, bus duct mains system is widely applied in engineering, and the structure of bus duct product sets
Meter is also from air-insulated type to dense insulation type, from outer cover of steel plate to aluminum alloy casing, progressively
Achieve update;In prior art, bus duct includes upper cover plate, lower cover and two
Bus is placed in side plate, and the containing cavity body formed between upper cover plate, lower cover and side plate
Bar, but, the space limited due to accommodating cavity is more fixing, therefore, and each bus duct
May be only available for the bus bar of respective numbers, the most true for the bus bar quantity in power system
In the case of fixed or needs are changed, the range of bus duct just seems and compares limitation, often
Need to change bus duct, improve expenditure cost, and of different types due to bus bar,
Present bus duct can not isolate, and causes sorting and maintenance to be difficult to, and due to bus
Bar is loose, does not has pressing plate, causes the bus bar in bus duct mixed and disorderly.
