Abstract
The shunt tripping device for a double-breakpoint breaker comprises an outer casing and a casing which are clamped together. A movable iron core, an electromagnetic system, an auxiliary spring, a shaft, a spring, a connecting rod and a level arm are positioned inside the outer casing. The movable iron core is retained inside a retaining groove of the level arm, one end of the auxiliary spring is retained onto the electromagnetic system, the other end of the auxiliary spring is retained onto the inner wall of the outer casing, and the movable iron core is connected with the auxiliary spring. The shaft penetrates through the auxiliary spring and the electromagnetic system, a micro switch is positioned on a lateral side of the outer casing, the spring and the connecting rod are sleeved on a shaft extending out of the outer casing, and the connecting rod contacts with the micro switch. The shunt tripping device for the double-breakpoint breaker is small in size, reliable in movement and beautiful in appearance, convenient in transportation, store and installation as an integral module, and is capable of providing various voltage classes, and is provided with contacts so that resources of auxiliary contacts of the breaker are not occupied.
Description
Technical field: the utility model relates to a kind of release, especially a kind of shunt release that is applied on the dual-interruption point breaker.
Background technology: shunt release is the widely used annex of circuit breaker, according to the design feature of dual-interruption point breaker, cube little, modularization, and it is convenient to change, the reliability height.
The utility model content: at above-mentioned the deficiencies in the prior art, the utility model provides a kind of simple in structure, dual-interruption point breaker shunt release that volume is little.
For achieving the above object, the technical solution adopted in the utility model is: the dual-interruption point breaker shunt release, comprise shell and housing, and both are connected together, also comprise the moving iron core that is in the shell, electromagnetic system, secondary spring, axle, spring, connecting rod and lever arm.Moving iron core is stuck in the draw-in groove of lever arm.Secondary spring one end is stuck on the electromagnetic system, and the other end is stuck on the outer casing inner wall, and moving iron core is connected with secondary spring.Axle passes secondary spring and electromagnetic system.Sensitive switch is in the side of shell.Spring and connecting rod are enclosed within on the axle that shell stretches out.Connecting rod contacts with sensitive switch.
The utility model volume is little, reliable in action, good looking appearance; As an integral module, transportation stores easy for installation; Different electric pressures can be provided; Do not take the resource of the auxiliary contact of circuit breaker, from contact-carrying.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an outside drawing of the present utility model
Fig. 3 is a cut-away drawing of the present utility model.
Fig. 4 is a fundamental diagram of the present utility model.
Embodiment:
As depicted in figs. 1 and 2: the dual-interruption point breaker shunt release, comprise shell 1 and housing 10, both are connected together, and also comprise being in moving unshakable in one's determination 3 in the shell 1, electromagnetic system 6, secondary spring 4, axle 5, spring 7, connecting rod 8 and lever arm 2.Moving unshakable in one's determination 3 are stuck in the draw-in groove of lever arm 2.Secondary spring 4 one ends are stuck on the electromagnetic system 6, and the other end is stuck on shell 1 inwall, and moving unshakable in one's determination 3 are connected with secondary spring 4.Axle 5 passes secondary spring 4 and electromagnetic system 6.Sensitive switch 9 is in the side of shell 1.Spring and 7 connecting rods 8 are enclosed within on the axle that shell 1 stretches out.Connecting rod 8 contacts with sensitive switch 9.
Operation principle:
Just often the contact of sensitive switch 9 disconnects (see figure 3), and the voltage that applies can not make 3 actions moving unshakable in one's determination of electromagnetic system.When being installed in shunt release in the circuit breaker, connecting rod 8 contacts with the moving contact supporter of circuit breaker, fashionable at circuit breaker closing, drivening rod 8 is to illustrated direction motion (see figure 4), make little disconnection close 9 the closing of contact, if when the leading-out terminal S of this position shunt release (see figure 3) applies voltage, then electromagnetic system K gets electronic work, make 3 motions unshakable in one's determination, drive lever arm 2 to the action of diagram (see figure 4) direction, that gives breaker mechanism separates power F of fastener, makes circuit breaker tripping separating brake.At this moment the contact of sensitive switch 9 disjunction power supply immediately.The protection electromagnetic system is the phase energising seldom, and shunt release is inoperative when breaker open operation.
