Description
Technical field
The utility model belongs to switch cabinet grounding switch technical field, more particularly to a kind of electronic connecing of manual priority operation
Ground switch interlocking device.
Background technology
Electronic earthed switch interlocking mechanism, under normal circumstances can be electronic and manual, two kinds of operator schemes.But such as
When fruit electric operating, Manual operation handle is inserted into handle hole and operated, and without fool proof structure, holds very much
Accident easily occurs.And if desired staff's manual operation switch cabinet earthing knife-switch, and what motor-operating mechanism was not disconnected
In the case of, this is possible to cause maloperation, causes the accident, it could even be possible to jeopardizing the life of staff.Therefore,
Motor-operating mechanism is cut off when being operated manually earthing knife-switch, i.e., it is manually operated preferentially perform it is particularly important.
The content of the invention
In view of the deficienciess of the prior art, the utility model provides a kind of electric ground switch connection of manual priority operation
Locking device, manually and electronic two kinds of modes of operation and deposit but the same time can only a kind of operation of mode of operation, operation handle insertion
When in handle hole, electrically operated power supply is cut off at once, realizes that manual priority operates.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of electricity of manual priority operation
Dynamic ground switch interlocking device, including operating shaft, microswitch and Manual operation handle, in addition on the inside of switch cabinet board
Portable plate, bent plate and axle, the portable plate are provided with the valve of protrusion switch cabinet board, portable plate top connecting spring, the bullet
The spring other end is fixed on switch cubicle, and portable plate bottom is provided with platform, and the microswitch is fixed on bent plate, on the bent plate
Provided with the pilot hole to be moved up and down for axle, axle is positioned in pilot hole, and axle top passes through stage clip and the platform of portable plate bottom
Connect；Switch cabinet board is provided with handle hole, and during Manual operation handle insertion operation hole, portable plate moves downward compression press spring, pushes away
Moving axis moves downward, and touches microswitch, microswitch closure, electronic failure；When Manual operation handle extracts handle hole, spring
Portable plate is driven to move, reset upwards.
Further, portable plate top side is connected with connecting plate one, and connecting plate one is by rotating axis connection connecting plate two, institute
State connecting plate two and be provided with elongated slot, connecting lever on connecting plate one, the connecting lever can move up and down in the elongated slot of connecting plate two, connecting plate two
By connecting rod and operation axis connection, during electric operating, valve is closed, and operating shaft rotates, and connecting lever is transported in the elongated slot of connecting plate two
It is dynamic.
Compared with prior art, the utility model advantage is：It is simple in construction, it is easily operated, realize manually and electronic two
Kind of mode of operation and deposit but the same time can only a kind of mode of operation operation, when in operation handle insertion operation hole, electric operating
Power supply at once cut off, electronic failure, realize manual priority operate；During electric operating, valve is closed, and operating shaft rotates, connecting lever
Moved in the elongated slot of connecting plate two, do not drive other parts, operated safer.
Brief description of the drawings
