Abstract
The utility model relates to the technical filed of energy saving equipment which is applied in a submerged arc furnace smelting system in metallurgical industry, which particularly relates to a secondary low-voltage compensation device of a submerged arc furnace. The utility model aims at providing a secondary low-voltage compensation device of a submerged arc furnace to overcome the problems of a submerged arc furnace in the prior art that an electric stove production rate is lowered and electric energy quality can not be guaranteed. The technical proposal which is adopted by the utility model is that the secondary low-voltage compensation device of a submerged arc furnace comprises an electric stove short network and a flexible cable, wherein the electric stove short network respectively comprises a single phase a-x, a single phase b-y and a single phase c-z, and self-healing low-voltage parallel capacitors are arranged on the three single phases, and the self-healing low-voltage parallel capacitors are connected on +/-300mm of the connector between the electric stove short net and the flexible cable. The secondary low-voltage compensation device of a submerged arc furnace has the advantages of reducing additional consumption of a transformer and an electrified wire netting, effectively improving power factor, prolonging the service span of a stove lining, and guaranteeing the production efficiency of the electric stove and the electric energy quality.
Description
Technical field:
The utility model relates to the energy-saving equipment technical field that is applied to metallurgy industry mine heat furnace smelting system, is specifically related to a kind of ore furnace secondary low-voltage compensation device.

The electrical system of existing mine heat furnace smelting is mainly connected to form successively by parts such as short net system, water-cooled cable, electrode system and the burner hearths of high voltage supply network, substation transformer, electric furnace primary side supply network, powerful furnace transformer, low-voltage and high-current.
The problem that prior art exists is: when the hot furnaceman in ore deposit did, the impedance unbalance of the three characteristics of the middle term can cause three-phase power imbalance.The local furnace wall infringement of this phenomenon seriously can cause the molten bath inequality of being heated, and stove is turned in one's mind and shortened useful life, thereby influence electric furnace productivity ratio, and the quality of power supply also can not get assurance.
Summary of the invention:
The utility model will provide a kind of ore furnace secondary low-voltage compensation device, to overcome the problem that electric furnace productivity ratio reduces and the quality of power supply can not get guaranteeing that prior art exists.
For overcoming the problem that prior art exists, the technical solution adopted in the utility model is: a kind of ore furnace secondary low-voltage compensation device, comprise electric furnace short net and flexible cable, comprise on the described electric furnace short net three single-phase, be respectively single-phase a-x, single-phase b-y and single-phase c-z, its special character is: be provided with self-healing low-voltage shunt capacitor 1 on single-phase a-x, single-phase b-y and the single-phase c-z, described self-healing low-voltage shunt capacitor 1 is connected millimeter place, connecting portion+/-300 of electric furnace short net and flexible cable.
Compared with prior art, the utility model has the advantages that: by improving the utilance of metallurgical transformer, secondary side low-voltage, high-current circuit, increase and smelt effective input power, improve the unbalance condition of three phase power fast, thereby reduce the supplementary load loss of transformer and electrical network, effectively improve power factor, stove is turned in one's mind and is prolonged useful life, has guaranteed the electric furnace productivity ratio and the quality of power supply.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Description of reference numerals:
The 1-formula low-voltage shunt capacitor of healing.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described in detail.
A kind of ore furnace secondary low-voltage compensation device, comprise electric furnace short net and flexible cable, comprise on the described electric furnace short net three single-phase, be respectively single-phase a-x, single-phase b-y and single-phase c-z, be provided with self-healing low-voltage shunt capacitor 1 on single-phase a-x, single-phase b-y and the single-phase c-z, described self-healing low-voltage shunt capacitor 1 is connected millimeter place, connecting portion+/-300 of electric furnace short net and flexible cable.
The self-healing low-voltage shunt capacitor 1 that is adopted uses in the electric furnace low-voltage compensation apparatus, has significantly reduced the spoilage of shunt capacitor, has effectively improved the operational reliability of this device.
