Description

Ore Smelter Energy-Conservation Short Network System

Technical field

The utility model relates to a kind of short net system, especially a kind of Ore Smelter Energy-Conservation Short Network System.

Background technology

At present, the hot stove in ore deposit is lacked the more energy-conservation connected mode of net referring to Fig. 1, comprise transformer (1), transformer (2), transformer (3), the hot stove in ore deposit (4), with the electrode (5) that is connected with each transformer, electrode (6), electrode (7), and three groups of three-phase copper pipes forming by copper pipe (8), copper pipe (9), copper pipe (10) three-phase copper pipe and copper pipe (11), copper pipe (12), copper pipe (13) three-phase copper pipe and copper pipe (14), copper pipe (15), copper pipe (16) three-phase copper pipe respectively.As can be known from Fig. 1, three transformers are that isosceles are arranged on around the hot stove in ore deposit, cause the short net of three-phase uneven, though transformer (3) towards being that wiring face is over against the stove heart, and copper pipe (14), copper pipe (15), the equal in length of copper pipe (16) three-phase copper pipe, but because transformer (1), transformer (2) towards not being that wiring face is over against the stove heart or connected electrode, make transformer (1), be connected with three of the electrode length of copper pipe of transformer (2) is inequality, be copper pipe (8), copper pipe (9), the length of copper pipe (10) three-phase copper pipe and copper pipe (11), copper pipe (12), the length of copper pipe (13) three-phase copper pipe has nothing in common with each other, thereby cause the three-phase resistance difference, cause three-phase loop current skewness, have a strong impact on the operating efficiency of the hot stove in ore deposit, also cause the loss of electric energy.

In addition, the connection of short net distance not only relates to the material usage of copper pipe, also the efficiency of the short net of influence, the material usage of the connection distance copper pipe of short net is big, the resistance of short net is big, and the power circuit loss is many, and the connection of opposite short net is apart from weak point, the consumption of copper pipe is little, the resistance of short net is little, and the electric energy line loss is few, however, the connection distance of short net is not to be short more good more, because also will consider safety factors such as environment temperature and insulation.At present the connection of short net distance neither beeline, transformer (1) to electrode (5), transformer (2) to electrode (6), transformer (3) to the distance of electrode (7) is respectively 8005mm, 8005mm, 7705mm, because of resistance is directly proportional with the length of conductor, thereby also just caused the extra loss of electric energy.
