Embodiment Construction
[0010] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples cited are only used to explain the present invention, and not used to limit the scope of the present invention.
[0011] Such as figure 1 , image 3 As shown, a solid-insulated switchgear interlocking mechanism is composed of a slider 1, an isolating switch hole baffle 10, a crank 6 connecting rod 5 slider 8, a crank connecting rod slider mechanism, and a cable compartment door 9. The block 1 is located on a smooth plane and is connected to the circuit breaker through the brake wire 3. The isolation switch hole baffle 10 is located on the smooth plane at the upper end of the slider 1 and can move left and right. The isolation switch handle 7 is located on the upper end of the isolation switch hole baffle 10 The crank 6 connecting rod 5 slider 8 mechanism is located at the right end of the isolation switch hole baffle 10, the crank 6 is loca...

The invention relates to the field of mechanical interlocking, in particular to a solid insulation switch cabinet interlocking mechanism. The solid insulation switch cabinet interlocking mechanism is composed of a sliding block, a disconnecting switch hole baffle, a crank connecting rod sliding block mechanism and a cable chamber door. The sliding block is arranged on a smooth plane and is connected with a circuit breaker through a braking wire, the disconnecting switch hole baffle is arranged at the upper end of the sliding block and can move left and right, and a disconnecting switch handle is arranged at the upper end of the disconnecting switch hole baffle. The crank connecting rod sliding block mechanism is arranged at the right end of the disconnecting switch hole baffle. A crank is arranged at the upper end of the disconnecting switch hole baffle and is in linkage with the disconnecting switch handle, the crank is connected with a connecting rod to drive the sliding block, and the cable chamber door is arranged at the lower end of the crank connecting rod sliding block mechanism. According to the solid insulation switch cabinet interlocking mechanism, a solid insulation switch cabinet can open the cable chamber door only when the circuit breaker is disconnected and a disconnecting switch is turned off, the disconnecting switch hole baffle can be blocked after the cable chamber door is opened, so that the disconnecting switch can not be turned on, and operator personal safety and device safety are effectively guaranteed.
Description
Technical field [0001] The invention relates to the field of mechanical interlocking, in particular to an interlocking device for solid insulation switch cabinets. Background technique [0002] At present, there are few interlocking mechanisms for safe operation of insulated switchgear devices on the market. When operating the insulated switchgear devices, workers will inevitably cause various misoperations due to carelessness, which will cause great safety risks to personal safety and equipment safety. , Easy to cause accidents. Summary of the invention [0003] The purpose of the present invention is to overcome human injuries and equipment damage caused by man-made misoperation of the solid insulation switchgear device. An interlocking mechanism for insulated switch cabinets is provided. [0004] The technical scheme adopted by the present invention to solve its technical problems is a solid insulation switch cabinet interlocking mechanism. It is composed of a slider, an isola...
