Abstract

The utility model discloses an electromagnetic coil for triggering unloading of a vacuum circuit breaker mechanism. The electromagnetic coil comprises a shell, a coil and a movable iron core shaft, wherein the coil is arranged in the shell; one end of an L-shaped installation plate is fixed with an end face of the shell, and the other end of the L-shaped installation plate is suspended; the movable iron core shaft penetrates through a central hole of the coil, one end of the movable iron core shaft extends out of the end face of the shell, and the other end of the movable iron core shaft extends out of the L-shaped installation plate; an annular flange is arranged at one end of the movable iron core shaft, which extends out of the L-shaped installation plate; and a return spring is sleeved on the movable iron core shaft and positioned between the annular flange and the L-shaped installation plate or between the annular flange and the shell. Plug-in type installation of the electromagnetic coil and the vacuum circuit breaker mechanism can be realized, and the electromagnetic coil is high in installation efficiency and replacement efficiency.

Description

A kind of solenoid that triggers the unloading of vacuum circuit-breaker mechanism

Technical field

The utility model relates to vacuum circuit-breaker manufacturing technology field, and especially a kind of being installed in triggered the solenoid that vacuum circuit breaker operating mechanism is carried out the unloading action in the vacuum circuit breaker operating mechanism.

Background technology

In vacuum circuit-breaker manufacturing technology field; A trigger unit need be set on the operating mechanism of vacuum circuit-breaker; The operating mechanism that is used for the Long-distance Control vacuum circuit-breaker is carried out the operating mechanism execution unloading action of unloading action or manual triggers vacuum circuit-breaker; Existing trigger unit adopts the solenoid that has the movable core axle mostly; Through control coil the electric operating mechanism that the movable core axle is moved trigger vacuum circuit-breaker is carried out the unloading action; Or manually push the operating mechanism that the movable core axle triggers vacuum circuit-breaker and carry out the unloading action, but this solenoid that has the movable core axle all need utilize its housing of a plurality of key screws to be fixed on the side plate of vacuum circuit breaker operating mechanism when installing, install and change cumbersome, speed is slow; The distance of the side plate of movable core axle center and operating mechanism is fixing can't the adjustment simultaneously, reduces its application flexibility.

The utility model content

The technical problem that the utility model will solve provides a kind of solenoid that triggers the unloading of vacuum circuit-breaker mechanism, has realized the plug-in type installation between ability and the vacuum circuit breaker operating mechanism, installs and change the efficient height.

For achieving the above object; The technical scheme of the utility model is: a kind of solenoid that triggers the unloading of vacuum circuit-breaker mechanism; Comprise housing, coil, movable core axle; Coil is contained in the housing, and L type mounting panel one end and the housing end face fixes, the other end is unsettled, movable core axle are through that an end stretches out the housing end face in the centre bore of coil, the other end stretches out outside the L type mounting panel; The movable core shaft extension goes out the outer end of L type mounting panel and is provided with annular flange flange, and a back-moving spring is through and is between said annular flange flange and the L type mounting panel on the movable core axle or is between said annular flange flange and the housing.

Further improve, the width of the unsettled end of said L type mounting panel makes the unsettled end of L type mounting panel peg graft convenient greater than fixing the width of an end with the housing end face like this.

Further improve, the unsettled end of said L type mounting panel is provided with a plurality of strip installing holes, makes the utility model also can adopt screw to fix, and further expands the scope of application again.

The utility model plugs with regard to the side plate that has draw-in groove on unsettled end of L type mounting panel capable of using and the vacuum circuit breaker operating mechanism because mounting panel is that L type and one of which end are unsettled, and the efficient height is therefore installed and changed to its installation and removal speed just than comparatively fast.

In addition; Because mounting panel is that L type and one of which end are unsettled; Its unsettled end and movable core axle centre distance are just convenient to be changed; Through changing the distance that different L type mounting panels just can change unsettled end of L type mounting panel and movable core axle center, further satisfy the needs of vacuum circuit breaker operating mechanism different designs.

Embodiment

Below in conjunction with accompanying drawing and concrete execution mode the utility model is done further explain.

Fig. 1 is to shown in Figure 4; A kind of solenoid that triggers the unloading of vacuum circuit-breaker mechanism; Comprise housing 1, coil 2, movable core axle 3; Coil 2 is contained in the housing 1, and L type mounting panel 4 one ends 41 fix with housing 1 end face, the other end 42 is unsettled, and movable core axle 3 is through that an end 31 stretches out housing 1 end face in the centre bore of coil 2, the other end 32 stretches out outside L type mounting panel 4 one ends 41; Movable core axle 3 stretches out L type mounting panel 4 one ends 41 outer ends 32 and is provided with annular flange flange 321; One back-moving spring 5 is through and is on the movable core axle 3 between said annular flange flange 321 and L type mounting panel 4 one ends 41, and when the hole that L type mounting panel 4 one ends 41 let movable core axle 3 pass was big, back-moving spring 5 also can be between said annular flange flange 321 and the housing 1.

The width of L type mounting panel 4 unsettled ends 42 is greater than fixing the width of an end 41 with housing 1 end face, and L type mounting panel 4 one ends 41 can be arranged on the mid portion of a unsettled end 42 Widths.

On said L type mounting panel 4 unsettled ends 42, be provided with a plurality of strip installing holes 421,, further expand its range of application so that the utility model also can adopt screw to fix.

Fig. 5, shown in Figure 6; When the utility model is used; Can a draw-in groove 101 be set on the side plate 10 of vacuum circuit breaker operating mechanism earlier, utilize on the draw-in groove 101 of the utility model L type mounting panel 4 unsettled ends 42 shown in being plugged on, a screw 30 also capable of using is locked on the screwed hole 102 on the side plate 10 and carries out spacing to L type mounting panel 4 unsettled ends 42; Movable core axle 3 stretches out the mechanism 20 of an end 31 sensing execution unloadings of housing 1 end face at this moment; Coil 2 when electric, movable core axle 3 moves to the mechanism 20 that carries out unloading, the mechanism 20 that unloading is carried out in an end 31 touchings of movable core axle 3 makes the vacuum circuit-breaker unloading; When coil 2 must not when electricity, also can let the vacuum circuit-breaker unloading through pushing mechanism 20 that movable core axle 3 make 31 touchings of one of which end carry out unloading.

Below only be preferred embodiment of the utility model, the change that those skilled in the art does to be equal to by claim all falls into the protection range of this case.
