Embodiment
Below in conjunction with accompanying drawing, specify the utility model.
Back of the present utility model door interlock switch cabinet overall architecture is to be made of a tank bracket, rear side at tank bracket offers the back door, and by the mode of operation of lock tube, thereby the fail safe that has improved switch cubicle greatly to the unlatching at back door and the interlock control internal breaker of locking.
See also Fig. 1, the partial schematic diagram when it is opened for door interlock switch cabinet back door behind the utility model.Lock tube 3 is arranged on the posterior edges place of tank bracket 1, and it runs through tank bracket 1.The front end of lock tube 3 is provided with a tapered end 4, and an end of tapered end 4 connects part in compression 5, and tapered end 4 and part in compression 5 are protruding from tank bracket 1 together.Part in compression 5 links to each other with standing part 6 again, and the cross section of standing part 6 is bigger, and its cross section is corresponding with the hole shape that tank bracket 1 is run through, and non-rotatably is stuck in the tank bracket 1.The rear end indent of lock tube 3 has a fixing hole 10, action bars 7 be arranged in the fixing hole 10 after an elastic mechanism 9 is connected, the elastic mechanism 9 of present embodiment is a spring.And action bars 7 interfixes by bolt 11 and lock tube 3, and the other end of action bars 7 is connected to the circuit breaker of switch cubicle, is used for controlling according to the rotation of itself mode of operation of circuit breaker.
Back door 2 is provided with a lockhole 8, and the shape of lockhole 8 is corresponding with the shape of tapered end 4, and the size of lockhole 8 is less than the cross section of part in compression 5.When back door 2 was closed, as shown in Figure 2, tapered end 4 stretched out from lockhole 8, and part in compression 5 can be pushed down in the edge of lockhole 8, and part in compression 5 is produced inside pressure.After part in compression 5 is under pressure, make elastic mechanism 9 be compressed, and standing part 6 is inwardly stretched out from tank bracket 1 and break away from.This moment is not because standing part 6 can be subjected to the inhibition of tank bracket 1 again, so lock tube 3 just can be rotated.
See also Fig. 3, it is the partial schematic diagram the during locking of door interlock switch cabinet back door behind the utility model.During operation, only need turn tapered end 4 just can drive action bars 7 and together rotate, thereby the mode of operation of circuit breaker is controlled, and make circuit breaker be shaken the service position.
See also Fig. 4, it is the circuit theory diagrams of action bars control circuit breaker of the present utility model.Wherein S1 is an earthed switch, and S2 is a killer switch, when 2 lockings of back door, understands chainly with earthed switch S1 conducting, thereby with killer switch S2 short circuit, makes its operation invalid.Certainly, back of the present utility model gate interlock also can carry out interlocked control to the miscellaneous equipment in the switch cubicle except the control circuit breaker.
The course of action of lock tube 3 when being convenient to understand the back door better and closing, the existing front schematic view that shows lock tube 3 separately see also as Fig. 5, and in conjunction with Fig. 1, Fig. 2, shown in Figure 3, the tapered end 4 of present embodiment is an elliptical shape that it is positioned at lock tube 3 foremost.The rear end of tapered end 4 connects part in compression 5, and part in compression 5 is circular, because its cross section greater than the lockhole on the back door 8, therefore can be subjected to exerting pressure of lockhole 8.Be connected and fixed part 6 after the part in compression 5 again, standing part 6 is square (its cross section also can be that hexagon or other have the shape of water caltrop), it is arranged in the tank bracket 1, because the inhibition of square water caltrop, make standing part 6 in tank bracket 1, to rotate, could rotational fixation part 6 and have only standing part 6 and tank bracket 1 to break away from back when closing (be back door 2), and then to the circuit breaker release.
The utility model can come the mode of operation of circuit breaker in the control switch cabinet by the interlocking of back door lock tube, could operate circuit breaker when therefore only closing at the back door.In other words, when operating personnel by opening the back door, and internal unit debugged or when safeguarding, circuit breaker is the state that is in outage, thereby the fail safe that has improved switch cubicle greatly.
More than disclosed only be several specific embodiment of the present utility model, but the utility model is not limited thereto, any those skilled in the art can think variation, all should drop in the protection range of the present utility model.
