Description
Technical field
The present invention relates to a kind of low-voltage power supply and distribution system technical field.
Background technology
In the known technology, the low-voltage power supply mode connects in the mode of a plurality of power units as adopting a current supply circuit, is divided into following three kinds: a kind of for the outlet circuit breaker connects a pre-branched cable, each branch cable is by a plurality of power units; Another kind of each branch cable is connected on the leader cable by penetrating cable clamp for the outlet circuit breaker connects a leader cable, and each branch cable connects a plurality of power units; The third connects concentration bus duct one time for the outlet circuit breaker, and the jack switch case is connected with bus each branch cable on the bus duct by being plugged on, and each branch cable connects a plurality of power units.
The weak point of above supply power mode is, the basis of leader cable or main bus bar sectional area is connected to the summation of power unit load on leader cable or the main busbar for all, pass through rationally on this basis, calculate accurately, finally determine the sectional area of leader cable or main bus bar.Be far longer than the sectional area of each branch cable like this with regard to the sectional area that has caused leader cable or main busbar, branch cable is many more, and it is many more that sectional area differs.
For the distribution of electric current on leader cable or main busbar, be unbalanced, the closer to the power supply circuit breaker, electric current on leader cable or the main busbar is big more, otherwise far away more from the power supply circuit breaker, the electric current on leader cable or the main busbar is more little, do not hold until leader cable or main busbar, the electric current on leader cable or the main busbar is tending towards equating with the electric current of not holding branch cable.
In above-described known technology, the sectional area of leader cable or main bus bar is thrown with the electric current that is passed through and is accomplished fully, reasonably mates.Under normal circumstances, the ampacity on very big one section leader cable or the main busbar is the current value that passes through greater than its inside.Clearly, the supply power mode in the known technology exists some not exclusively reasonable, some uneconomic factors.Under the situation that current pre-branched cable, concentration bus duct and penetrating cable clamp are widely used, at non-ferrous metal, especially under the situation that the copper valency grows to even greater heights, its uneconomic factor has just more loomed large.
