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.
The table says that they use foreign equipment but the transformer is of domestic origin.
The sizes of the transformer are impressive.
The transformers are separated by fireproof walls so that three transformers could continue working in case of a fire on one of them.
The ventilators cool down the radiators. In summer the noise is terrible. Right now there is no voltage here, works will start in autumn.
