Abstract

The utility model discloses an energy-saving device for a rotary contactor. The utility model is composed of a contactor, a releaser and a lock, wherein, the lock is composed of a locking part and a connecting rod. The movable arm of the contactor is locked by adopting a mechanical mode when the utility model acts, and the contactor can still work normally after a working coil is powered off. The releaser is operated with low current to maintain the closing of contact of the contactor which can be operated with great current. The utility model has the advantage of obvious energy-saving effect. The utility model is suitable for rotary AC contractors, DC contractors, intermediate frequency contractors, etc.

Description

Rotary contactor energy-saver

The utility model relates to a kind of energy saver, particularly relates to a kind of energy saver of rotary type contactor.

At present in the electrical control field, be extensive use of the rotary type contactor, because contactor must work long hours, its actuating coil is in power supply state for a long time so that the contacts of contactor adhesive, like this must consumed power, especially use in big current suppling circuit, the actuating coil power consumption is very big, causes energy waste.

The purpose of this utility model is, provides a kind of to society, does not change the mechanical performance and the electric property of rotary type contactor, and reduces the energy saver of its actuating coil power consumption greatly.

The utility model can be realized with following mode:

The energy saver that comprises contactor and release also is provided with lock between contactor and release.

One termination of contactor swing arm is connected with locked head, lock is made up of Lock Part and connecting rod, the left end of Lock Part is top porose arc, right-hand member also is an arc, the joint of left and right sides arc is the fulcrum of Lock Part, the right-hand member arc has back-moving spring near the fulcrum place, and " L " shape connecting rod vertical headers and Lock Part right-hand member head rest are near, and the horizontal termination of " L " shape connecting rod links to each other with the release electromagnet.

The vertical component of " L " shape connecting rod has arc curved, and fulcrum is supported on the arc crook of " L " shape connecting rod.

Advantage of the present utility model:

1, by the release that works in little electric current, control the swing arm of mechanical lockout contactor, make blocked contactor, under the situation of actuating coil outage, operate as normal still, the operating current of release is 1/10 of a contactor coil operating current only, becomes big current work and is little current work, and energy-saving effect is remarkable;

2, be applicable to contactors such as rotary type interchange, direct current, intermediate frequency.

Fig. 1 is the utility model release condition structural representations;

Fig. 2 is the utility model working state schematic representation;

Fig. 3 is the utility model electrical schematic diagram.

As shown in drawings, the swing arm 2 of rotary type contactor is affixed with locked 3, swing arm 2 other ends and fulcrum 1 are slidingly connected, the left end of Lock Part 4 is top porose arcs, right-hand member also is an arc, the junction of left and right sides arc is the fulcrum 5 that Lock Part 4 can rotate around it, the right-hand member arc has back-moving spring near fulcrum 5 places | 6|, the vertical headers of " L " shape connecting rod 7, near with Lock Part 4 right-hand member head rests, " L " shape connecting rod 7 horizontal terminations link to each other with release electromagnet 10, in the embodiment shown in the figures, be hinged between the vertical component of " L " shape connecting rod and the horizontal component, pin joint | 9|, connecting rod 7 vertical component stage casings have arc curved, and fulcrum 8 is supported on the arc crook of connecting rod 7.The course of work is as follows: after pressing start button AN, the work of all switching on of contactor (C among Fig. 3) and release (C ' among Fig. 3), do moving downward of circular arc for locked 3 that is fixed on the contactor movement arm 2, pass the hole on the Lock Part 4 left end arcwall faces, prop up the S point among Fig. 1, elongated insertion part 3 is oppressed the lower limb in holes simultaneously, it is the B point place among Fig. 1, make Lock Part 4 around fulcrum 5, the B point is downward, E towards on do circular motion, when pressing the AN button, the work of also switching on of release C ' coil, release C's ' is moving, decide the arm adhesive, the upper and lower side of drivening rod 7 is around fulcrum | and 8| turns clockwise, contact with the E face of Lock Part 4 when rotating to connecting rod 7 upper end F faces, the F face props up the E face, it is planar support, form Lock Part 4 right-hand member height as shown in Figure 2, the state that left end is low, utilize elongated insertion part 3 to contact with the B point securely, decontrol the AN button this moment, the coil blackout of contactor C, no current, but its moving contact and auxiliary contact all can well contact, keep release C ' work, dispose procedure is as follows: press stop button TN, release C ' outage is within it under the effect of portion's spring force, release electromagnet 10 is released and resets, the horizontal component of electromagnet 10 drivening rods 7 and vertical part are around fulcrum | and 8| rotates counterclockwise, and overcomes the frictional force between F face and the E face, and the F emaciated face is from the E face, lose the right-hand member of the Lock Part 4 of connecting rod 7 supports, under the effect of back-moving spring 6, clockwise rotate around fulcrum 5, this moment, Lock Part 4 left end bore edges B points upwards rotated, locked the 3 S point with the left end arc breaks away from, and return from the left end hole, this moment, contactor C restored, and release C ' and lock all are in initial condition.
