This time we’ll visit a new steel plant in Ukraine that will be launched very soon.
One arc furnace with capacity of 180 tons is under construction now. It will produce 1 million 300 thousand tons of steel a year. 600 employees are working here. It will be launched in spring 2012.
A new electric station was built. It has two electric transformers, one of which is shown in the picture.
A 330 kV cable line was laid from the Pridneprovskaya Thermal Power Plant to feed the electric station. The line is 14 km long.
A voltage measuring transformer decreases voltage from 330 kV to 100 kV for protective circuit. A high-voltage surge arrester protects the electric station from switching overvoltage.
Disconnecting switches are needed to create a visible circuit break while carrying our repairs. Safety is very important here.
330 kV sulfur-hexafluoride circuit breaker.
5 sets of circuit-breakers.
