Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, 2, the circuit breaker with brake-dividing locking function described in the utility model comprises: top cover 1 and pedestal 3, and top cover 1 fastens the insulation crust that constitutes circuit breaker up and down with pedestal 3,
Be provided with self-locking release 4 in the pedestal 3,
Described top cover 1 is provided with an edge insulator socket 6, and edge insulator 5 is inserted in the edge insulator socket 6,
Shown in Fig. 7,8, front and back sidewalls in the described edge insulator socket 6 are provided with two phosphorus bronze sheet that are oppositely arranged 71, and in the time of in edge insulator 5 is not inserted into edge insulator socket 6, two phosphorus bronze sheet 71 touch under himself flexible effect, two phosphorus bronze sheet, 71 formations that touch are electrically connected reliably
A power supply terminal of self-locking release 4 directly is connected with a utmost point of circuit breaker end of incoming cables, and another power connector end of self-locking release 4 is connected with a phosphorus bronze sheet 71 on the edge insulator socket 6,
Another phosphorus bronze sheet 71 on the edge insulator socket 6 is connected with another utmost point of circuit breaker end of incoming cables.
On the basis of technique scheme, the shape of described edge insulator 5 is not limit, and Fig. 6 shows a kind of shape of the edge insulator that can select 5.As long as when guaranteeing that edge insulator 5 inserts in the edge insulator socket 6, two phosphorus bronze sheet, 71 separation in the edge insulator socket 6, effective insulation are got final product.
On the basis of technique scheme, described self-locking release 4 can be selected the finished product self-locking release of public offering on the market for use.Shown in Fig. 4,5, described self-locking release 4 comprises armature 8 and release iron core 9, and armature 8 is connected with draw bar 7 in being assemblied in pedestal 3.
Circuit breaker with brake-dividing locking function described in the utility model, the course of work is as follows:
In the time of in edge insulator 5 is inserted into edge insulator socket 6, two phosphorus bronze sheet 71 in the edge insulator socket 6 are insulated card 5 and intercept, can not form and be electrically connected, as shown in Figure 8, at this moment, the power supply of self-locking release 4 is disconnected by edge insulator socket 6 places, and self-locking release 4 is not worked, this moment, the function of circuit breaker and existing common residual current circuit breaker, breaker of plastic casing were in full accord, and operating grip 2 can freely divide, close a floodgate.
After the edge insulator in the edge insulator socket 65 is pulled out, two phosphorus bronze sheet 71 in the edge insulator socket 6 touch under himself flexible effect, two phosphorus bronze sheet, 71 formations that touch are electrically connected reliably, as shown in Figure 7, at this moment, the power supply of self-locking release 4 is by the 6 places conducting of edge insulator socket, and self-locking release 4 is started working, release iron core 9 and armature 8 adhesives on the self-locking release 4, armature 8 pulling draw bars 7.
Referring to Fig. 1,3 as can be known: when armature 8 pulling draw bars 7, button again 10 on the draw bar 7 is threaded off with tripping 12, tripping 12 is interlock rocking arm 11 and moving contact 14 under the tension of main extension spring 13, make rocking arm 11 and rocking arm 11 upper handles 2 get back to N and OFF centre position such as Fig. 2, spur moving contact 14 simultaneously moving contact 14 and fixed contact 15 are disconnected as Fig. 3, this moment, circuit breaker disconnected.
Because being pulled out back self-locking release 4, edge insulator 5 keeps operating state, make armature 8 hook draw bar 7, draw bar 7 can not be resetted, button again 10 on the draw bar 7 can not interlock with tripping 12, lose the strong point of power between tripping 12, rocking arm 11 and the main extension spring 13, handle 2 just not stretchy rocking arm 11, tripping 12 and main extension spring 13 moving contact 14 is engaged with fixed contact 15, circuit breaker can not close a floodgate again, as Fig. 3, reach the brake-dividing locking purpose.
