INDICATORS AND INTERLOCKINGS OF SWITCHED POSITIONS FOR DEVICES OF POWER SWITCHES Russian patent published in 2004 - IPC

FIELD: applicable in switch-gears of medium voltage with an air insulation with functional indications "Power switching", "Disconnection" and "Grounding".

SUBSTANCE: the indicators and interlockings of the switched positions are built jointly in the control modules and realized by means of indicating sliders and interlocking sliders, which are guided in the middle plate that is located between the protective plate on the face side and faces the interior of the devices of the power switches by the retaining plate. The middle plate has a quantity of guide holes complied with the positions and contours of the indicating and interlocking sliders. The protective plate has a quantity of inspection holes complied with the positions and contours of the indicating and interlocking sliders. The retaining plate has a quantity of through holes complied with the positions and contours of the indicating and interlocking sliders.

EFFECT: unified construction of the indicators and interlockings for power switches of various types, reduced overall dimensions for building-in of these indicators and interlockings.
