Description

An electrically operated interlock mechanism

technical field

The utility model relates to the technical field of switch cabinets, in particular to an electric operation interlocking mechanism.

Background technique

Medium voltage 4000A and above high current fixed switchgear isolating switch operating force is very large, manual operation is very inconvenient, generally using electric operating mechanism to achieve, but there will be problems in the operation sequence and related interlocking when using electric operating mechanism . The existing interlocking mechanism has potential safety hazards, which is not conducive to the safety, continuity and stability of power supply, and brings unstable factors to production and life.

Therefore, it is urgent to create a device that can solve the above problems, reduce the probability of accidents, and bring convenience to people's production and life.

Utility model content

The purpose of this utility model is to provide a new type of interlock mechanism device for the above-mentioned technical problems in the prior art, which can realize the interlock between the manual and electric operation of the electric mechanism, and the interlock between the electric operation of the isolating switch and the upper circuit breaker. Interlocking meets the five-proof requirements of the switchgear, and the interlocking is simple, reliable and easy to debug.

The utility model is achieved through the following technical solutions:

An electric operation interlocking mechanism, including an interlocking plate, an electric mechanism, a pressure plate, a micro switch and a locking electromagnet, the electric mechanism is provided with a slider, and the interlocking plate is provided with a A chute, a micro switch is fixed on the electric mechanism below the interlocking plate, a locking electromagnet is fixed on the electric mechanism above the interlocking plate, a pressing plate is arranged on the interlocking plate, and the interlocking plate Guided by the slider and fixed by the pressing plate, the interlocking plate can move up and down to open or close the operating shaft hole of the electric mechanism.

As a preference, the electric mechanism is also provided with a spring connected to the bottom of the interlocking plate.

In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

Compared with the prior art, the interlock mechanism designed by the utility model has the advantages of simple structure, convenient and reliable operation, high safety, easy installation and debugging, etc., and realizes the interlock between manual and electric operation of the electric mechanism, and the isolation switch electric The interlock between the operation and the upper-level circuit breaker meets the five-proof requirements of the switchgear, greatly reduces the probability of accidents, and brings convenience to people's production and life.

Description of drawings

The utility model will be explained by way of example and with reference to the accompanying drawings, wherein:

Fig. 1 is a structural schematic diagram of the interlocking plate of the present invention in a reset state;

Fig. 2 is a structural schematic diagram of the interlocking plate of the present invention in the state of lifting;

Figure 3 is a schematic structural diagram of the interlocking plate of the present invention;

Marks in the figure: 1—interlock plate, 2—electric mechanism, 3—pressure plate, 4—spring, 5—micro switch, 6—slider, 7—locking electromagnet, 8—chute, 9—operating shaft hole .

Detailed ways

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

As shown in Figures 1 to 3, an electrically operated interlock mechanism includes an interlock plate 1, an electric mechanism 2, a pressure plate 3, a micro switch 5 and a locking electromagnet 7, and the electric mechanism 2 is provided with a slider 6. The interlocking plate 1 is provided with a chute 8 matching the shape and size of the slider 6. A micro switch 5 is fixed on the electric mechanism 2 below the interlocking plate 1. The electric motor mechanism above the interlocking plate 1 A locking electromagnet 7 is fixed on the mechanism 2, and a pressing plate 3 is arranged on the interlocking plate 1, and the interlocking plate 1 is guided by the slider 6 and fixed by the pressing plate 3, and the interlocking plate 1 can move up and down to open or close The operating shaft hole 9 on the electric mechanism 2 is also provided with a spring 4 connected to the bottom of the interlocking plate 1 on the electric mechanism 2 .

As shown in Figure 1, the interlocking plate 1 is in the reset state, the operating shaft hole 9 on the electric mechanism 2 is closed, the interlocking plate 1 presses the micro switch 5, the electric circuit is connected, and the electric opening and closing operation can be performed. If manual operation is performed, the interlocking plate 1 needs to be lifted up and inserted into the crank handle. When the upper level circuit breaker is not disconnected, the locking electromagnet 7 above the interlocking plate 1 is in a de-energized state, and the dead bolt is stretched out to lock, and the interlocking plate 1 It cannot be lifted up to prevent the accident of operating the isolating switch with load on the outgoing line. When the superior circuit breaker is disconnected, the locking electromagnet 7 is electrically unlocked, and the interlocking plate 1 can be lifted up for manual operation.

As shown in Figure 2, the interlock plate 1 is in the lifting state, the micro switch 5 is in the released state, the electric circuit is disconnected, and the electric opening and closing operation cannot be performed. Rapid flying injury accident occurred.

The specific embodiments described above have further described the purpose, technical solutions and beneficial effects of the present utility model in detail. It should be understood that the above descriptions are only specific embodiments of the present utility model and are not intended to limit the present invention. utility model. The utility model extends to any new feature or any new combination disclosed in this specification, as well as the steps of any new method or process or any new combination disclosed.
