Embodiment Construction
[0007] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:
[0008] see figure 1 One end of the toggle rod 1 is fixedly connected with the slide plate 2 of the transmission mechanism of the circuit breaker drawer 6, and the other end of the toggle bar 1 extends out of the slide plate 2. The micro switch support plate 3 is fixed on the bottom plate 4 of the drawer 6, and the micro switch support plate 3 and the toggle lever 1 are vertically arranged; three micro switches 5 are installed on the micro switch support plate 3, and the three micro switches The button of toggle switch 5 is to be fixed on the motion locus that toggle bar 1 stretches out slide plate 2 one ends; Terminal block is fixed on the side plate of drawer 6. The terminals of each microswitch 5 in the three microswitches 5 showing the th...

The invention relates to a universal circuit breaker equipped with a drawer. It includes a drawer with a circuit breaker, a toggle lever, a bracket, a micro switch, a fixed plate, a terminal block and a signal display device; the toggle lever is fixedly connected to the slide plate of the circuit breaker drawer transmission mechanism, and extends out of the slide plate; the bracket is vertical It is fixed on the toggle rod and fixed on the bottom plate of the drawer; three micro switches are fixedly installed on the bracket, and the buttons of the three micro switches are fixed on the sliding plate of the circuit breaker drawer transmission mechanism. On the movement track of one end of the toggling rod extending out, the terminal is fixed on the side plate of the drawer; the terminal of each micro switch is connected with the signal input terminal of the display device through the terminal of the terminal. Because the present invention outputs the switch position through the contact signal, the single pointer indication mode is changed, and the user can use the device to indicate the switch position, and can form an electrical interlock with other devices, so that the switch operation is safer and more reliable.
Description
Technical field [0001] The invention belongs to a circuit breaker, in particular to a universal circuit breaker equipped with a drawer. Background technique [0002] At present, the drawer of the known drawer-type circuit breaker only has a pointer-type indicator switch position device, so that not only the indication method is single, but also the remote control room cannot immediately and intuitively understand the on-site operation situation, and there are hidden dangers. Contact signaling device for position inside the drawer. Contents of the invention [0003] In order to solve the technical problems in the known technology, the present invention provides a universal circuit breaker equipped with a drawer that can provide a switch position signal. [0004] The technical scheme adopted by the present invention to solve the technical problems existing in the known technology is: it includes a drawer with a circuit breaker, and it also includes a toggle lever, a micro s...
