Detailed Description
As shown in fig. 1, it is a schematic diagram of an external structure of an interlocking distribution box with high safety according to a preferred embodiment of the present invention, and the interlocking distribution box includes a box body 13, a concealed socket 1, a button switch 14 and an indicator light 15. The button switch 14 includes an opening button 4 and a closing button 3, and the indicator lamp 15 includes an opening indicator lamp 5 and a closing indicator lamp 6 corresponding to the button switch 14.
As shown in fig. 2, it is the schematic diagram of the internal structure of the interlocking distribution box with high safety according to a preferred embodiment of the present invention, which includes a relay 8, a surge protector 9, a molded case circuit breaker 10, a mounting frame 12 and a ground bar 11. Moulded case circuit breaker 10 passes through bolt fixed mounting 12 on the installation frame, and relay 8 and surge protector 9 are all adorned in moulded case circuit breaker 10 left side, and ground connection row 11 is adorned in moulded case circuit breaker 10 right side.
As shown in fig. 3 and 4, when the distribution box is used normally, the external plug 2 is inserted into the concealed socket 1 at the bottom of the box body, and then the closing button 3 is clicked.
In this embodiment, the terminals of the concealed installation socket 1 are respectively connected with the surge protector 9, the relay 8 and the molded case circuit breaker 10 through conducting wires, and the other end of the surge protector 9 is connected with the ground bar 11. The concealed socket 1 is respectively provided with a main contact and an auxiliary contact 7
Further, when the plug 2 is pulled out, the auxiliary contact 7 of the concealed installation socket 1 connected with the plug is firstly opened, and then the molded case circuit breaker 10 is opened through the relay 8. When the plug 2 is not inserted or inserted in place, the plug 2 and the auxiliary contact 7 of the concealed socket 1 are always in the off position, and the molded case circuit breaker 10 is also always in the off position at the moment, so that the circuit cannot be switched on even if the closing button 3 is manually clicked.
The above-described embodiments are merely illustrative of the preferred embodiments of the present invention and are not intended to limit the spirit and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by the technical solution of the present invention by those skilled in the art should fall into the protection scope of the present invention, and the technical contents claimed by the present invention have been fully recorded in the claims.
