Abstract
The utility model relates to an electric leakage circuit breaker comprising a circuit breaker and an electric leakage module, wherein the circuit breaker comprises a circuit breaker shell as well as two live line connecting terminals and a bimetallic strip which are arranged in the circuit breaker shell; the electric leakage module comprises an electric leakage shell as well as a zero sequence transformer and two zero line connecting terminals which are arranged in the electric leakage shell; in the electric leakage module, a zero line braided wire passes through the zero sequence transformer and is connected with the two zero line connecting terminals; a live line hole is formed in the inner wall of the shell between the circuit breaker and the electric leakage module; and the zero line braided wire in the circuit breaker passes through the live line hole and the zero sequence transformer in the electric leakage module from the end of one live line connecting terminal, and then passes through the live line through hole again to return into the circuit breaker and be connected with the bimetallic strip. A live line in the circuit breaker is connected with the zero sequence transformer through the live line hole between the circuit breaker and the electric leakage module, without external winding, therefore, the electric leakage circuit breaker is more compact and smaller.
Description
Technical field
The utility model relates to a kind of residual current circuit breaker.
Background technology
Residual current circuit breaker comprises electric leakage module and circuit breaker; the live wire of residual current circuit breaker and zero line all will pass zero-sequence transformer; and zero-sequence transformer normally is arranged in the electric leakage module of residual current circuit breaker; and be connected live wire in the circuit breaker to pass zero-sequence transformer just need be with the live wire in the circuit breaker from the residual current circuit breaker outside around to the electric leakage module; pass the zero-sequence transformer in the electric leakage module; the track lengths of circuit is longer; cabling in circuit breaker and electric leakage module is more complicated also; again in order to protect outside lead; also need externally to install additional a lead-in wire cover, increased the volume that leaks disconnected circuit breaker.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, provides that a kind of volume is small and exquisite, the residual current circuit breaker of compact conformation.
For achieving the above object, the utility model adopts a kind of residual current circuit breaker, comprise circuit breaker and electric leakage module, circuit breaker comprises case for circuit breaker, be arranged on two hot terminal and bimetal leaf in the case for circuit breaker, the electric leakage module comprises the electric leakage shell, be arranged on zero-sequence transformer and two zero line binding posts in the electric leakage shell, there is the zero line litzendraht wire to pass zero-sequence transformer in the electric leakage module and connects two zero line binding posts, form the live wire hole on the shell wall between circuit breaker and the electric leakage module, live wire litzendraht wire in the circuit breaker passes zero-sequence transformer in live wire hole and the electric leakage module from hot terminal one end, and passes the live wire through hole once more and get back in the circuit breaker and be connected with bimetal leaf.
The beneficial effects of the utility model are to be connected with zero-sequence transformer by the live wire hole between circuit breaker and the electric leakage module by the live wire in the circuit breaker, need not make residual current circuit breaker compact, small and exquisite more by outside coiling.
Described live wire hole is arranged on the corresponding bimetal leaf of outer casing inner wall and the position between the binding post.The position in live wire hole makes the cable run distance of live wire litzendraht wire the shortest, saves material.
Described live wire hole comprises that the circuit breaker through hole of case for circuit breaker on electric leakage module outer wall and the corresponding circuit breaker through hole of electric leakage shell are arranged on the electric leakage through hole on the outer wall.Circuit breaker and the split of electric leakage module are provided with, and need offer through hole on two shells.
