Electrical system is composed of reactor, capacitor and inductor to connect triangle balanced three phase load.

The electric system is composed of supply power and control equipment: power unit of the pot is an integrated electric cabinet including automatic air switch, contactor, voltage regulator, balancing reactor, capacitor mutual inductor, etc. The three-phase equilibrium and compensating have been assembled inside the electric cabinet and adjusted during commissioning, not adjusted during working order. The electric control system is centered on a control desk. The control desk controls process control, status parameter indication, fault status indication, security protection and electric chain, etc. The panel of control desk is equipped with various electrical parameter display instruments, which used for monitoring the operation status of GI pot. The signal alarm system includes light and sound signal. Through the PLC control system to achieve power regulation, pot bath temperature automatic control, monitoring operation process, indicating operation parameters, indicates accident status, electric interlock and alarm, etc The temperature can be controlled manually or automatically. The control signal is consist by thermocouple and temperature controller. The temperature of pot and the deviation value of temperature control shall be set on temperature controller.Temperature control circuit adopts duplex system, one for use and the other for standby. The power control of two sets of power units adopts one control signal. To avoid high-power impact, the other two sets shall additionally equip with time lag start circuit.In the integrated electrical cabinet, balance transformer and reactor is the largest two parts, heat energy consumption occupies more than 70% of electric control cabinet itself .As for transformer and reactor, Wisdom electric has completely designed according to the higher standard. There are some equipment have been put into operation, the noise of the transformer and reactor, calorific value is significantly lower than in the past. Especially the autotransformer, no-load test (core loss) space-time load current is 20% lower than in the past.The noiseless operation of normal work. Energy saving effect is obvious in the new designed system.
