6 upper end of ground connection junction panel is equipped with the second sincere sub-portion 20, and the second sincere sub-portion 20 is also that a concave end other end is prominent The structure risen.
Chain roller 5 is equipped between the first sincere sub-portion, 18 and second sincere sub-portion 20, one end of the chain roller 5 is hinged On the shell.
The chain roller 5 has the first state with the ground connection limit cooperation of junction panel 6 in the first sincere 18 top pressure of sub-portion With the second state for constituting limit cooperation with combined floodgate junction panel 2 in the second sincere 20 top pressure of sub-portion.
When disconnecting switch is closed a floodgate, combined floodgate junction panel 3 is driven by isolation axis 4 to be rotated, meanwhile, the of the combined floodgate junction panel 3 Chain roller can be pressed in the recess of the second sincere sub-portion 20 of ground connection junction panel by the protrusion of one sincere sub-portion 18, and due to first sincere 18 top pressure of sub-portion is grounded junction panel and is then limited by chain roller 5, cannot be rotated at this time in the chain roller.It at this time cannot be right Earthing switch is operated.
In disconnecting switch separating brake, combined floodgate junction panel 3 is driven by isolation axis to be rotated, and the first sincere son of combined floodgate junction panel 3 The protrusion in portion 18 leaves the upper end of chain roller 5, and chain roller 5 releases the limit for being grounded junction panel at this time, and ground connection connects at this time Therefore jam plate is it can be selected that at this time can operate earthing switch.
When earthing switch closes a floodgate, grounding shaft 7 drives ground connection junction panel rotation, is grounded the second sincere sub-portion of junction panel at this time The chain roller of the upward top pressure of protrusion so that chain roller is in the recess of the first sincere sub-portion of combined floodgate junction panel, to real Existing limit of the chain roller to combined floodgate junction panel so that disconnecting switch cannot be operated.
The upper end of the combined floodgate junction panel is equipped with the interlocking gear to link with circuit breaker operation mechanism.The interlocking gear can be with In disconnecting switch divide-shut brake, combined floodgate junction panel is limited, it is avoided to be misused in separating brake/combined floodgate.
The upper end both sides of the combined floodgate junction panel 3 are equipped with the chain slot 16 that limit cooperation is constituted with interlocking gear, and two A chain slot 16 constitutes limit cooperation with interlocking gear when switch on and switch off respectively.Two states are realized by interlocking gear Limitation, i.e., in close a floodgate when, the limit by interlocking gear to combined floodgate junction panel prevents it from manual brake separating, or is locating When separating brake, the limit by interlocking gear to combined floodgate junction panel prevents it from closing by hand.
The combined floodgate junction panel 3 is equipped with guide groove 17, and guide pin 10, the guiding are equipped in the guide groove 17 Slot 17 is convex structure, is distributed as the center of circle so that axis is isolated, limits the movement locus of combined floodgate junction panel.
The ground connection junction panel bottom end is equipped with displacement slot 19, and limit pin shaft 11, the limit are equipped in the displacement slot 19 Position axis pin 11 can slide along displacement slot, and two states of conjunction are opened and be grounded to corresponding ground connection respectively at the both ends of displacement slot 19, with ground connection Axis is that the center of circle is distributed at circular arc, the motion track for limiting ground connection junction panel.
The interlocking gear includes the Interlocked operation mechanism that latch lever 2 is linked with it, and the latch lever is by chain behaviour Make mechanism and drives second state with the first state limited with combined floodgate junction panel and releasing and the limit of combined floodgate junction panel.The company Locking bar can be pulled by Interlocked operation mechanism, extended or retracted, to play the limit to combined floodgate junction panel and release the behaviour of limit Make.
The Interlocked operation mechanism includes operating shaft 25, which is directly used in the operation machine in control phase pole The control of structure, and the setting interlocking connecting lever 14 in operating shaft 25, which connect with latch lever 2, for driving Latch lever 2 moves, and separating brake roller 15 is arranged in operating shaft, and the upper end of the separating brake roller 15 is correspondingly arranged separating brake cam 12, When separating brake cam 12 rotates, separating brake roller can be touched, drives operating shaft rotation, so that latch lever is retracted, releasing pair The limit of combined floodgate junction panel, i.e., after automatic brake separating, the latch-release of latch lever just can divide disconnecting switch manually Closing operation avoids being operated manually under "on" position.
Meanwhile the Interlocked operation mechanism is additionally provided with auxiliary switch, the auxiliary switch passes through link mechanism and operating shaft It is linked, which includes the auxiliary switch connecting lever being linked with auxiliary switch, and auxiliary switch connecting lever passes through connecting rod It is linked with the connecting lever being arranged in operating shaft, the extended and retracted operation of latch lever can also be realized using auxiliary switch.
The Interlocked operation mechanism is additionally provided with junction panel 13, and the junction panel is matched by buffering connecting lever with operating shaft linkage It closes, the junction panel has when latch lever stretches out and the jam plate of tank surface 26 constitutes the first state of limit cooperation and even When locking bar is retracted and the jam plate of tank surface releases the second state of limit cooperation.The junction panel drives by operating shaft, and Sliding slot is which is provided with, positioning pin is equipped in sliding slot, so that it is determined that the movement locus of junction panel, stretches out and the company of combined floodgate in latch lever When jam plate constitutes limit cooperation, the end of junction panel is placed in the upper end of jam plate at this time, and jam plate is pushed down, and prevents it upward from outside It opens, avoids in "on" position, someone carries out manual brake separating by opening jam plate, and is only retracted in latch lever and releases the company of combined floodgate When the limit state of jam plate, junction panel is then driven and moves inward at this time, not in the direction of motion positioned at jam plate, so as to To open jam plate, manual divide-shut brake or ground connection operation are carried out to it.
Embodiment is not construed as limitations of the present invention, any spiritual improvements introduced based on the utility model, It should all be within the protection scope of the utility model.
