G - 1 a (F) the mechanical procedure lock error protected stationary type high voltage switch cabinet, used in industrial and mining enterprises become sub-station, ac 50 hz, three-phase voltage 3-10 kv single busbar systems as acceptance and distribution of electrical energy use.GG - 1 a (F) mechanical program locks prevent error type high voltage switch cabinet is GG - 1 a type of high voltage switch cabinet improved derived products.Due to the switch cabinet structure is simple, the volume is bigger, to prevent wrong operation procedures after the lock has to help them avoid loading powder, isolating switch, prevent the operator mistakenly charged interval;Prevent charged hanging earthing line and isolating switch;To prevent false points, or circuit breaker five kinds of wrong operation function.Therefore facilitate monitoring, installation, and production, at the same time can reliably prevent electrical wrong operation, to ensure that equipment and personal safety.
