VDAP Series

DISTRIBUTIVE COMPACT SWITCHGEAR

for indoor installation, extensible version

Vacuum compact cubicles series VDAP are manufactured for rated voltages 12, (17,5) and 24 kV. The main purpose of VDAP compact switchgear is energy distribution in transformer substations and nodal points of distributive networks. Compact switchgear series VDAP is designed for indoor installation, at normal service conditions, in accordance with IEC 62271-200 and IEC 60694. Extensible version enables various solutions for each required single line diagram. Vacuum compact switchgear series VDAP are highly reliable and available, as well as completely independent on environmental conditions. Overall dimensions of VDAP compact switchgear are considerably reduced in comparison with classic air insulated cubicles.

All live parts are placed into gas-insulated steel container. The container is filled with SF6 gas, which provides mutual insulation of current path elements, as well as insulation to the earth level potential. The arc quenching takes place in vacuum interrupters built both in circuit breaker and load break switches. SF6 gas is not used as arc-quenching medium, so the gas replacement has been eliminated. This feature provides complete environmental acceptability of this product.

Power transformer protection is enabled by vacuum circuit breaker, which is controlled by protective electronic relay. Besides the obligatory manual drive, compact modules series VDAP can be equipped with motor drive and set of releases for remote control of each device. There is possibility of complete automatization of distributive transformer substations, regarding various specific requirements for remote control and monitoring. This series of compact switchgear is suitable for distributive network nodal points, where remote control and monitoring is required.
