In Fig. 1 as seen, accessories B is close to by on circuit breaker 1a, the 1b of several horizontal bindings, the breaker assembly 1 that 1c constitutes with the one side, each circuit breaker is by distribution comb 7 power supplies that link to each other with three-phase busbar (not shown), this accessories B is used to monitor the folding condition of circuit breaker, or is used for finding out such as faults such as overcurrent or short circuits.
With reference to Fig. 2 to Fig. 6, wherein show two different embodiment of the present invention, therefrom visible this accessories B is made of housing 2, and housing 2 is made of two different parts that are called master unit 8 and link 9.Master unit 8 comprises a tangible vertical component 22 and two arms 23,24 perpendicular to the sidewall extension of this part 22.Link 9 is made of an obvious c-shaped lateral part 25, step-like lateral part 26 on the other side is connected these two parts 25,26 with one a coupling part 27, the end portion 12 that the inwall of these lateral parts 25,26 and coupling part 27 has formed an above-mentioned master unit 8 can be located in recess 11 wherein, and two arms 23,24 of master unit 8 ride against respectively on the upper surface of above-mentioned lateral part 25,26.Master unit 8 comprises the contact that is called as auxiliary contact of three formation changers, these three contact 3a, 3b, 3c is mechanically connected in the mechanism of the circuit breaker that accessories B links with it on the one hand, use lead 13 on the other hand, 30 are connected respectively on three binding posts 4 of the above-mentioned step lateral part 26 that is positioned at link 9, above-mentioned binding post 4 is electrically connected on the signaling switch plate (not shown), the signaling switch plate is then linked for example on the control desk, the C shape lateral part 25 relative with step lateral part 26 of link 9 comprises a recess 10, therefrom passes through for the broach 7a of distribution comb 7.
According to these embodiment of the present invention, with suitable device link 9 be mounted to can around master unit 8 also promptly around one with the vertical axis X rotation of plane P of the broach 7a of above-mentioned electric comb 7.
Please especially referring to Fig. 2 and Fig. 3, therefrom as seen, in first specific embodiment of the present invention, above-mentioned auxiliary contact 3 are to link on the binding post 4 with the lead 13 in the hole 15,14 on connecting portion 27 upper walls that pass the lower wall that is located at master unit 8 respectively and link 9.
In another embodiment shown in Fig. 5 and 6, above-mentioned three binding posts 4 are to be connected on three auxiliary contact 3 by three contacts that are called wiping contact.Therefore in master unit 8 both sides three contact pin 16,17,18 and 19,20,21 are arranged respectively, three contact pin 16,17,18 and 19,20,21 of every side are connected on three auxiliary contact 3a, 3b, the 3c with three lead 31a, 31b, 31c and 31d, 31e, 31f respectively.
Fig. 7 and Figure 8 shows that another embodiment.According to present embodiment, link 29 is installed on the master unit 28 turningly, thereby electric comb 7 can be contained in the line side or the load-side of circuit breaker.In this embodiment, master unit 28 comprises a rectangle part 22 and two arms 23,24, this rectangle part 22 has a groove 28a, one aforesaid is connecting the C shape part 25 of link 29 and the part that is known as connecting portion 29a of stepped portion 26 is packed into wherein by means of suitable device, should be noted that, though being connected in these figure and between not shown binding post 4 and the auxiliary contact 3, but as previously mentioned, availablely pass the lead in two apertures on master unit and the link or realize that with wiping contact this is connected.
Below, for the concise and to the point in addition description of the installation of the link in the various embodiments of the present invention 9,29 on master unit 8,28.
Fig. 2 and embodiment illustrated in fig. 3 in, as long as link 9 is rotated 180 ° relative to master unit 8, just can be transformed into link 9 from the position that makes electric comb 7 be contained in the circuit breaker line side shown in Fig. 2,3 and make electric comb 7 install to the position (Fig. 4) of circuit breaker load-side.
This rotation makes protuberance 39 be resisted against on second stop 310 on the link 9, so, if make this link 9 Rotate 180 ° more in the opposite direction, just can realize counter motion from the load-side installation site to the installation site, line side, and point out as top, reach the purpose of unlikely cut-out lead 13.
In Fig. 5,6 illustrated embodiments, link 9 from a position convert to the another location be by with previous embodiment same procedure reach.In Fig. 5 and 6, thereby binding post 4 is electrically connected to and makes distribution comb 7 install to the line side in the contact pin 16,17,18.Link 9 changes 180 ° on the either direction of both direction after, binding post 4 will be electrically connected in the contact pin 19,20,21, thereby electric comb 7 can be installed on the load-side position.In this embodiment, rotate and to be not limited to 180 °, this is because lead 13 has cut danger unlike the situation of the foregoing description, so just can be on same direction link 29 be rotated on two 180 ° in succession.
In Fig. 7 and 8 illustrated embodiments, then, master unit 28 and link 29 realize that electric comb 7 is contained in the conversion of the position of load-side (Fig. 8) from position to the electric comb 7 that is contained in line side (Fig. 7) by being disengaged.Accomplish the disengaging of this joint with the way that link 29 is deviate from from groove 28a, then, rotating connecting part 29 engages it and is fixed on (Fig. 8) among the groove 28a more again.
Thereby, the invention provides a kind of annex that is exclusively used in the indication circuit-breaker status of simplicity of design, because it makes distribution comb both can be contained in the line side, can be contained in load-side again, so can be used for many country variants.
The present invention never is only limited to the foregoing description that only illustrates as an example certainly.
On the contrary, present invention includes all technical equivalents thing and the combination thereof of stating device, as long as these combinations meet spirit of the present invention.
