Abstract
The utility model relates to a separate-exciting release for a circuit breaker, which comprises a base part and an electromagnetic control part, wherein the base part comprises a base (1), a microswitch (11) fixed on the base (1), a revolving plate (8) pivoted and connected with the base (1) through a rotating shaft (9) of the revolving plate, wherein the revolving plate (8) is butted with a contact of the microswitch (11). The electromagnetic control part comprises a coil curl (4), a still iron core (2), a movable iron core (3) and a traction rod (7), wherein the coil curl is fixed on a coil bobbin, the still iron core and the movable iron core are arranged in the inner cavity of the coil curl (4), and the traction rod is connected with the movable iron core (3). The utility model is characterized in that the traction rod (7) is pivoted and connected with the base (1) through a rotating shaft (5) of the traction rod. The utility model is a releasing shaft for driving the circuit breaker, and the utility model has the advantages of larger releasing force and reliable operation.
Description
Technical field
The utility model relates to a kind of shunt release that can carry out straighforward operation to circuit breaker.
Background technology
In the prior art, the shunt release of circuit breaker comprises base part and Electromagnetic Control part, described base part by pedestal, be fixed in sensitive switch on the pedestal, form with the finger plate that the pedestal phase pivot is connected by the finger plate rotating shaft, be with back-moving spring in the described finger plate rotating shaft, one end and the finger plate of this back-moving spring are inconsistent, the other end and pedestal are inconsistent, and described finger plate is against on the contact of sensitive switch; Described Electromagnetic Control partly comprises the coil that is fixed on the coil rack, the static iron core in the coil inner chamber, the moving iron core in the coil inner chamber, the draw bar that is connected with moving iron core.Because be that trip shaft by the moving circuit breaker of hook makes circuit breaker tripping, so tripping force is less, because shunt release is installed in the inside of circuit breaker, the temperature rise in the circuit breaker work will exert an influence to the performance of shunt release in addition.
Summary of the invention
The purpose of this utility model is to provide a kind of dependable performance, easy for installation, shunt release that tripping force is big.
The technical solution of the utility model is: a kind of shunt release of circuit breaker, comprise base part and Electromagnetic Control part, described base part by pedestal, be fixed in sensitive switch on the pedestal, form with the finger plate that the pedestal phase pivot is connected by the finger plate rotating shaft, be with back-moving spring in the described finger plate rotating shaft, one end and the finger plate of this back-moving spring are inconsistent, the other end and pedestal are inconsistent, and described finger plate is against on the contact of sensitive switch; Described Electromagnetic Control partly comprise the coil that is fixed on the coil rack, the static iron core in the coil inner chamber, the moving iron core in the coil inner chamber, with the draw bar that moving iron core is connected, described draw bar is connected with described pedestal phase pivot by the draw bar rotating shaft.
The utility model has the advantages that: because draw bar is connected with the pedestal phase pivot by the draw bar rotating shaft, therefore draw bar plays the effect of lever, the trip shaft that is used to control circuit breaker makes the traction rod end of circuit breaker tripping opposite with the direction of motion of moving iron core, therefore the utility model is the trip shaft that promotes circuit breaker, have bigger tripping force, use reliable.
