Abstract
The invention discloses an anti-tripping circuit combining a breaker and relay protection. The anti-tripping circuit combining the breaker and the relay protection mainly comprises an anti-tripping unit, a closing unit and an opening unit of the breaker, and a closing supervision unit, a tripping supervision unit and an anti-tripping unit of the relay protection. The closing supervision unit is in series connection with the anti-tripping unit of the breaker, and is mainly composed of a tripping position supervision relay coil, a breaker normally closed auxiliary contact and a normally closed contact of anti-tripping relay which are in series connection. After a closing supervision unit loop is in series with the normally close auxiliary contact of the breaker and the normally closed contact of the anti-jumping relay, and the breaker closes, the closing supervision unit loop is separated from an anti-tripping unit loop of the breaker to eliminate interferences by the closing supervision unit. At the same time, the closing supervision unit and the breaker closing unit form a loop, and the closing supervision unit can supervise a breaker closing loop, so that an original function is saved. The design of a new loop enables anti-tripping of the breaker and the relay protection to be realized in a same loop, and an anti-tripping function is realized through integrating advantages of the anti-tripping modes of the breaker and the relay protection.
