Description
Structure of symbol B-H/XX:
The B is the Block
X - tension Class, And
XX - Number the designating design
Blocks are intended for reception of electric energy on voltage of 35 kV, production of kommutation (operations of inclusion and shutdown) of current of the main chains, protection against atmospheric and switching retension, against currents of short circuit, transformation, transformation of current of 35 kV of chains of management, the alarm system and measurements.
Blocks are intended for a complete set of complete transformer substations, block 1000 … 16000 kVA of stationary use and transported on a sled as again constructed, and at expansion or change of schemes of the main electric chains.
Blocks conform to requirements, rated for a climatic modification of Wu Yi of UHL, category of placement, in the atmosphere of types I and II in accordance with GOST 15150 and GOST 15543.1 with isolation of high-voltage devices of category A and B in accordance with GOST 9920 (by request), height above sea level to 1000 m, wind speed to 15 m/s at an ice wall thickness to 20 mm, in the absence of ice, wind speed to 40 m/s.
