Low-voltage switchgear / air-insulated / power distribution

Intelligent switchboards are equipments providing an automatic control of electric energy distribution. The switchboard is produced according to customer requirements, according to which a particular combination of switching devices together with required control and measuring equipment is created. Standard sets of intelligent switchboards are designed for low-voltage operations (up to 500 V with a current load up to 1000 A). In case of non-standard requirements it is possible to exceed these limitations.

The switchboard has two or three independent inputs. One or two of them are from the outer distribution network and the second, respectively third is from the genset. Only one input of the switchboard is permanently active, i.e. the switchboard works only from one input. Switching over from one input to the other occurs only in case of:

a total voltage loss on three or one of the active input phases
a voltage drop of one of the phases below 85% of nominal value
a voltage increase of one of the phases above 110% of nominal value

Voltage limitations at which the input is active are possible to vary in the range of 85% - 110% UN.

Inputs are equipped with mechanically blocked contactors which disable their simultaneous closing, although their simultaneous switching-off is possible.
