FIELD: electrical engineering.SUBSTANCE: invention relates to electrical engineering, to switchgears. Gate device comprises board element made with possibility of movement between protective position, in which board element prevents access to fixed electric contacts of switchgear, and non-protective position, in which board element allows circuit breaker electric contacts of switchgear to connect to fixed electric contacts. Drive lever actuates board element, while moving circuit breaker of extracted non-working position to set working position in relation to switchgear. Locking unit provides fixation of drive lever and board element in safety position to prevent manual or undesired movement of board element, when circuit breaker is in extracted non-working position.EFFECT: technical result consists in reduction of energy consumption for housing heating.13 cl, 11 dwg |
