Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in more detail by the following examples.
The first execution mode
In the first execution mode of the present invention, the adjustment spring is fixed on the supporting mechanism away from an end of contactor main body, this supporting mechanism can be in contraction/direction of extension of adjusting spring, namely adjust on the deformation direction of spring and slide, switch to the position that pre-contact support is rebounded behind " ON " state with the fixed capacity contactor, and dynamically adjust the position that capacitor switching contactor is in whole pre-contact modules under " OFF " state.Thus, for the different multiple contactor main body of parameter, guaranteed that pre-contact was supported and the auxiliary mutual adhesive of supporting when capacitor switching contactor switched to " OFF " state.
Situation when for convenience of description, at first illustrating that in conjunction with Fig. 3 and Fig. 4 first embodiment of the invention is in " ON " state at capacitor switching contactor.Wherein, Fig. 3 is the front view that capacitor switching contactor is in its pre-contact modules under " ON " state, and Fig. 4 is the stereogram that capacitor switching contactor is in its pre-contact modules under " ON " state.
When capacitor switching contactor switches to " ON " state by " OFF " state, main contact on the contactor main body is supported to support 2 direction motions shown in the arrow in Fig. 3 by hook 5 band dynamic auxiliarys, adjustment spring 6 in the pre-contact support 1 this moment is near an end of contactor main body, namely contact a standing part (not shown) in the contactor housing away from a termination of moving contact spring 7 and compressed, until consequent active force makes pre-contact support the permanent magnet 3 on 1 and assists the iron block 4 of supporting on 2 to separate, that is, so that these two contact support sectors divide separately mutual.After two contact support sectors divide mutually separately, pre-contact support 1 under the elastic restoring force of adjusting spring 6 to rebounding with the direction of opposite direction shown in the arrow.
Support to adjust in 1 spring 6 away from an end of contactor main body in pre-contact, namely near an end place of moving contact spring 7, be provided with and the supporting mechanism 8 adjusting spring 6 and be fixedly connected with, this supporting mechanism is specifically as follows supporting bracket etc.Because this supporting mechanism direction perpendicular to paper in Fig. 3 is strip (this shape is more clearly illustrated) in Fig. 4, thereby in pre-contact support 1 process of rebounding, these supporting mechanism 8 meeting stop motions owing to the fixed contact (not shown) that touches pre-contact modules, and then cause whole pre-contact to support 1 stop motion.Because the installation site of the fixed contact of pre-contact modules is fixed in the capacitor switching contactor housing, thereby be in contact with it and position that this supporting mechanism 8 of stop motion stops is fixed, that is to say that the position that pre-contact support 1 stops to fix in the process of rebounding.
At this moment, there is no any deformation owing to adjusting spring 6, thereby this supporting mechanism 8 can contact with the pre-other parts that contact support 1, shown in the situation in the dotted ellipse circle that marks among Fig. 4, supporting mechanism 8 contacts with the upper ledge of forms 9.
Fig. 5 is the front view that capacitor switching contactor is in its pre-contact modules under " OFF " state in the first embodiment of the invention, and Fig. 6 is the stereogram that capacitor switching contactor is in its pre-contact modules under " OFF " state in the first embodiment of the invention.
When capacitor switching contactor switches back " OFF " state from " ON " state, auxiliary support 2 is to moving with the direction of opposite direction shown in the arrow, when pre-contact supports 1 and auxiliary when supporting 2 distances enough near, pre-contact support permanent magnet 3 on 1 and the iron block 4 in the auxiliary support 2 to attract each other and so that these two contact supports partly combine.At this moment, according to the parameter characteristic of contactor main body, auxiliary support 2 can along with the contactor main body continue to the direction of opposite direction shown in the arrow segment length of moving be the distance of L.Owing in advance contact support 1 and the marriage relation of assisting support 2, the pre-contact supports that 1 also can be to the distance L identical with the direction motion of opposite direction shown in the arrow under the promotion of assisting support 2.But meanwhile, supporting mechanism 8 since be fixed on the capacitor switching contactor housing in contacting of fixed contact and can't move, therefore this supporting mechanism can be the relative sliding of L within holding the forms 9 of adjusting spring 6, with respect to pre-contact support 1 generation length, and this slip causes adjusting spring 6 compressed identical length L.
At this moment, owing to adjusting spring 6 certain deformation has occured, thereby this supporting mechanism 8 is separated from the other parts that contact in advance support 1, produced certain interval, shown in the situation in the dotted ellipse circle that marks among Fig. 6, supporting mechanism 8 has certain interval with the upper ledge of forms 9.
When again switching to " ON " state at capacitor switching contactor, to the motion of direction shown in the arrow, pre-contact support 1 is because and the auxiliary also thereupon motion of marriage relation of supporting between 2 under the drive that the main contact of contactor main body is supported in auxiliary support 2.Adjust spring 6 and in this process, stretch back gradually original state, supporting mechanism 8 also breaks away from the contact condition with fixed contact afterwards, support 1 one arrow direction in the same way with pre-contact, until two contact support parts are separated from each other under the active force of adjusting spring 6 again, pre-contact supports that 1 is rebounded again.
The above has described the state variation of pre-contact modules in the capacitor switching contactor stateful switchover process.Can be found out by foregoing description, the adjustment spring is fixed on the supporting mechanism away from an end of contactor main body, because this supporting mechanism can touch the fixing fixed contact in position in the contactor housing in the process of rebounding with pre-contact support, thereby fixed capacitor switching contactor and switched to the position that pre-contact support is rebounded behind " ON " state.Simultaneously, because auxiliary being supported in pre-the contact still can drive pre-contact support after the mutual adhesive of support and continue motion one segment distance, thereby guaranteed for the different multiple contactor main body of parameter, pre-contact is supported all and can be supported mutual adhesive with auxiliary when switching to " OFF " state at capacitor switching contactor.
It will be appreciated by those skilled in the art that, when the position that this supporting mechanism is set and size, can be according to switch to " OFF " state when capacitor switching contactor after, the characterisitic parameter of a kind of contactor main body that the attracting state between pre-contact support and auxiliary the support is the most bad arranges, thereby makes it be applicable to simultaneously the multiple contactor main body of different parameters.
For example, can determine after capacitor switching contactor switches to " OFF " state from " ON " state, make auxiliary the support to a kind of contactor main body (the most bad situation) the shortest with the distance of direction of arrow rightabout motion.First the auxiliary initial position of supporting is determined the initial position of pre-contact support according to this contactor main body the time, and then jointly determines position and the size of this supporting mechanism according to the installation site of fixed contact in the pre-contact support initial position of determining and the contactor case.At this moment, distance L can be 0 or very little value, in other words when using this contactor main body, auxiliaryly just and in advance contact the support adhesive or the very short distance of only moving when supporting with the stop motion of contactor main body after adhesive.According to such supporting mechanism setting, when use makes auxiliary when supporting longer other kind contactor main body of move distance, guarantee in the time of just " OFF " state can being switched at capacitor switching contactor that pre-contact is supported and the auxiliary mutual adhesive of supporting, difference only is the auxiliary difference that is supported in the moving distance L of the follow-up reforwarding of adhesive of basis, and the length L that this supporting mechanism will be adjusted spring-compressed is thereupon different.
The second execution mode
Fig. 7 is the front view of the pre-contact modules of capacitor switching contactor in the second embodiment of the invention.
Second embodiment of the invention, can support that arrange two in 1 adjusts springs 6 in pre-contact, be arranged at respectively on the position corresponding with two moving contact springs 7, and lay respectively at the both sides of permanent magnet 3, particular location as shown in Figure 7.Be similar to the description in the first embodiment of the invention, adjust springs 6 for two and be fixed on respectively on the supporting mechanism at the end away from the contactor main body, these two supporting mechanisms can be arranged on the same level position among Fig. 7.
When switching to " ON " state at capacitor switching contactor, two supporting mechanisms 8 that are fixedly connected with an end of two adjustment springs 6 all can touch the fixed contact of pre-contact modules, thereby cause pre-contact to support 1 stop motion.When switching to " OFF " state at capacitor switching contactor, two supporting mechanisms 8 also all can be owing to supporting 1 relative sliding occur with respect to pre-contact with contacting of fixed contact in forms 9, thereby compress corresponding adjustment spring 6.
Because the permanent magnet both sides of supporting in pre-contact are provided with two supporting mechanisms, so that pre-contact is supported in the stressed more balance in the capacitor switching contactor stateful switchover process, more be conducive to the stable operation of equipment.
The 3rd execution mode
According to the 3rd execution mode of the present invention, also can as in the first execution mode, only arrange one and adjust spring 6, but it is arranged on the right positions of permanent magnet 3 among Fig. 7, but not as in the first execution mode, be arranged on the leftward position of permanent magnet 3.Arrange all similar with the first execution mode with corresponding supporting mechanism of this adjustment spring etc.
The above has described three execution modes of the present invention.It will be appreciated by those skilled in the art that, needs according to the industrial devices design, can be provided with at the diverse location of pre-contact modules the adjustment spring of varying number, and according to mentality of designing of the present invention, corresponding supporting mechanism is set to combine with these adjustment springs, realizing goal of the invention of the present invention, and reach the relevant art effect.
Technique scheme according to embodiment of the present invention, the adjustment spring is fixed on the supporting mechanism away from an end of contactor main body, this supporting mechanism can slide in contraction/direction of extension of adjusting spring, switch to the position that pre-contact support is rebounded behind " ON " state with the fixed capacity contactor, and dynamically adjust the position that capacitor switching contactor is in whole pre-contact modules under " OFF " state.Thus, guaranteed that pre-contact was supported and the auxiliary mutual adhesive of supporting when capacitor switching contactor switched to " OFF " state, guaranteed the safe operation of contactor equipment; Simultaneously, can make the pre-contact modules that comprises this design be applicable to the different multiple contactor main body of parameter, effectively reduce relevant equipment cost.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
