Abstract
A power supply controller of a copper melting furnace comprises two groups of voltage-regulating devices and compensation capacitors, and is characterized in that the two groups of voltage-regulating devices are respectively connected to an output terminal of a transformer, and the transformer converts a group of symmetrical three-phase power supplies into two groups of single-phase power supplies. Since the load characteristics of two groups of bi-phase power-frequency induction heaters are basically the same, three-phase current at an incoming terminal of the transformer can be basically balanced, and the defects of low power factor and electricity consumption caused by direct using of a three-phase power source can be effectively improved. The power supply controller has the advantage of energy conservation.
Description
Technical field
The utility model relates to electric equipment, specifically is the melting furnace power-supply controller of electric that uses in a kind of melting furnace equipment.
Background technology
Draw stove at present domestic two groups of two-phase line-frequency induction heaters are arranged, and two groups of line-frequency induction heaters are used the phase in the three phase mains respectively, control furnace temperature respectively by regulator, be easy to make three phase mains electricity consumption imbalance like this, thereby cause the reduction of power factor (PF), exist the big defective of power consumption.
Summary of the invention
The purpose of this utility model is the defective of depositing at prior art, proposes a kind of energy-conservation melting furnace power-supply controller of electric.
The purpose of this utility model is achieved in that a kind of melting furnace power-supply controller of electric of the present utility model, it comprises two groups of regulators and building-out capacitor, it is characterized in that two groups of regulators are connected to an output that three one group of symmetrical power source conversion is become the transformer of two groups of single phase poaer supplies.
Melting furnace power-supply controller of electric of the present utility model, the regulator of two groups of line-frequency induction heaters is connected an output that three one group of symmetrical power source conversion is become the transformer of two groups of single phase poaer supplies, because the load characteristic of two groups of two-phase line-frequency induction heaters is basic identical, can make the three-phase current of transformer incoming end in a basic balance, can improve effectively that the power factor (PF) that direct use three phase mains causes is low, the defective of power consumption, have energy-conservation characteristics.
Description of drawings
Fig. 1 is the structural representation of melting furnace power-supply controller of electric of the present utility model.
Embodiment
