In the metallurgical industry, the furnace with low voltage and high current must be the submerged arc furnace with large capacity. Generally, the dynamic coefficient of this kind of furnace is low, and the dynamic coefficient is one of the important reference indexes to measure the overall electrical performance of submerged arc furnace, which seriously affects the daily output and power consumption. The implementation of passive compensation of submerged arc furnace can improve the power coefficient and achieve the goal of energy saving and consumption reduction.

1、 Scope of application of the system

The reactive power compensation system of submerged arc furnace is suitable for ferroalloy submerged arc furnace and calcium carbide furnace in chemical system.

2： Composition and appearance of reactive power compensation system

Low voltage compensation system includes:

Compensation includes capacitor cabinet: there is a low-voltage compensation capacitor and switching switch.

High current short-circuit network: it has a fairly perfect short-circuit network system, which can be connected to the reactive power compensation of capacitors.

Automatic control cabinet: the compensation system can realize automatic measurement, automatic cutting and automatic control.

III Function and effect description of installing reactive power compensation

1. Improve the power parameters, increase the effective power, increase the output and the furnace condition of submerged arc furnace.

2. Most furnaces are overloaded for a long time. After compensation, the furnace can increase production by 8-10% without overload. The operation vibration and noise of boiler transformer and short network are reduced, and the service life of main equipment is prolonged.

3. The high-voltage line loss is well reduced, and the primary working voltage and electrode voltage are improved. The submerged arc furnace can still operate normally and economically under the condition of low system control voltage level.

4. It effectively reduces the impact of harmonics, improves the electrical parameters of the system, and improves the quality of electric energy products of enterprises.

5. Avoid being fined for low power factor.

6. The use of microcomputer controlled compensation equipment can automatically print the daily report, automatically count the time of power failure, automatically calculate and print the active and reactive power supply, and improve the management and operation level of the furnace.
