Background technology
Common communication power supply exchanges and is input as the input of two-way civil power, one road main confession, and one the tunnel is standby, when switching mutually under the online situation of two-way civil power while, for avoiding two-way city electrical short, leads to a disaster, and must disconnect one the tunnel earlier and just can be switched to other one the tunnel.When the two-way civil power is switched mutually under the online situation simultaneously, may because of misoperation when not disconnecting one the tunnel, closing other one the tunnel causes short circuit.
Summary of the invention
The purpose of this utility model is to provide a kind of miniature circuit breaker switch interlock device of avoiding causing because of misoperation two-way civil power short circuit accident.
To achieve these goals, the technical solution of the utility model is: miniature circuit breaker switch interlock device, it is characterized in that it comprises interlocking seat 1, first coupling spindle 2, second coupling spindle 3, interlocking lever 5, nut 10, interlocking axle 11, the upper and lower end parts of interlocking seat 1 is respectively equipped with second and connects axis hole 7, the first connection axis hole 6, first coupling spindle 2, second coupling spindle 3 pass first both ends that connect axis hole 6, the second connection axis hole, 7, the first coupling spindles 2, second coupling spindle 3 respectively and are exposed at respectively outside the interlocking seat 1; The middle part of interlocking seat 1 is provided with interlocking axis hole 13, the right-hand member of interlocking axle 11 is provided with axle cap 4, and the left part of interlocking axle 11 is provided with external screw thread, and the middle part of interlocking lever 5 is provided with axis hole, the left end of interlocking axle 11 passes axis hole, the interlocking axis hole 13 of interlocking lever 5, and nut 10 is spun on the left part of interlocking axle 11.
The left part of described interlocking axle 11 is with plain washer 8, spring washer 9, and plain washer 8, spring washer 9 are positioned at the right side of nut 10.
The left side central portion of described interlocking seat 1 is provided with U type groove 12, and nut 10 is positioned at U type groove 12.
The utility model adopts said structure, the left part of first coupling spindle 2, second coupling spindle 3 is arranged in two circular holes of first miniature circuit breaker 14, the right part of first coupling spindle 2, second coupling spindle 3 is arranged in two circular holes of second miniature circuit breaker 15, makes about the utility model quilt to be fixedly clamped; Interlocking lever 5 is positioned on the switching surface of first miniature circuit breaker 14, second miniature circuit breaker 15, rotation interlocking lever 5 bevels, make axle cap 4 compress interlocking lever 5 (being that interlocking lever 5 is fixing) by axle cap 4, nut 10, the switch of first miniature circuit breaker 14, second miniature circuit breaker 15 has only one for disconnecting shape, and another just can close; Mutual restriction by interlocking lever 5 realizes only can closing other one road civil power miniature circuit breaker to power devices under the situation that one road civil power miniature circuit breaker disconnects, and reaches by first miniature circuit breaker 14, second miniature circuit breaker, 15 online two-way civil powers and can not insert the purpose that realizes interlock function simultaneously; This device has been avoided when the two-way civil power is switched mutually under the online situation simultaneously, may because of misoperation when not disconnecting one the tunnel, closing other one the tunnel causes short circuit accident.Of the present utility model simple in structure, easily manufactured, cost is low, and is easy to assembly, dependable performance.
