Cells career outside single YaKNO-10 are high-voltage distributing devices for outdoor unit, are intended for connection, a power supply and protection of electric equipment of career excavators, for installation in lighting and primary circuits of a power supply of a pit, and also in places of accession to intra career transmission lines of 6 - 10 kV of consumers of electricity of the same power.
Cabinet of YaKNO-10 it is expected rated current to 630 A and a limiting current of shutdown of 20 kVA. The scheme of primary switching of a cell YaKNO-6(10) consists of input insulators of outdoor unit through passage, the disconnector, the high-voltage circuit-breaker with drives, current transformers, the voltage transformer with safety locks and the cable current transformer of zero sequence.
Structure of a symbol of a cell of YaKNO-10-H-U
YaKNO - a cell complete outdoor unit.
10; 6 - rated voltage of 10 or 6 kV.
X - number of the scheme of primary YaKNO10 connections.
At (T) - a climatic modification in accordance with GOST 15150.
Application of cells of YaKNO-10:
Cabinets of YaKNO-6 (10) serve for connection of electric excavators, high-voltage engines, power transformers, drilling rigs, high-voltage engines of drill trucks, drags, dredges, compressor and condenser units and other consumers. Cells of YaKNO-6(10) can be completed with skids for non-stationary use, for movement on career.
