Description
Technical field:
The utility model relates to transformer technology field, is specifically the interlock that a kind of fixed vacuum breaker joins switch cubicle.
Background technology:
Switch cubicle is a kind of electric equipment, and switch cubicle outside line is introduced into master switch in cabinet, then enters sub-control switch, and each shunt needs to arrange by it.As instrument, automatic control, motor magnetic switch, various A.C. contactors etc., what have also establishes hyperbaric chamber and low-pressure chamber switch cubicle, is provided with high voltage bus, as power plant etc.The interlock that current fixed vacuum breaker joins switch cubicle generally adopts construction of wire rope, but this structure can only unidirectionally be interlocked, and cannot realize two-way interlocking, make troubles to practical operation; And complex structure, steel wire rope Long-Time Service, be likely scratched and cause breakage, dependability is poor.
Utility model content
The technical problems to be solved in the utility model is, thering is provided a kind of utilizes the rotation of fixed vacuum breaker main shaft to realize mechanical interlocking, when realizing breaker closing can not operation isolation and vacuum circuit-breaker separating brake time could " five anti-" the mechanical interlocking functions of operation isolation, and two-way interlocking can be realized, the fixed vacuum breaker that structure is simple, dependability is good joins the interlock of switch cubicle.
The technical solution of the utility model is, a kind of fixed vacuum breaker with following structure is provided to join the interlock of switch cubicle, the operation board that it comprises baffle plate, is fixed on the guide plate on switch cubicle and is fixed on switch cubicle, one end of described baffle plate is hinged with the one end of the connecting lever that the main shaft of vacuum circuit-breaker is connected, described operation board is provided with the groove that the one end for baffle plate embeds, the centre of described guide plate is provided with through hole, the middle part of described baffle plate is positioned at the through hole of guide plate, and is provided with gap between the outer wall of baffle plate and the inwall of through hole.
The one end of the connecting lever that one end of described baffle plate is connected with the main shaft of vacuum circuit-breaker is hinged to be referred to, one end of described baffle plate is provided with the first installing hole, one end of described connecting lever is provided with the second installing hole, a screw rod is installed in the first installing hole and the second installing hole, at the last portion nut of screw rod.
The through hole of described guide plate and the groove location correspondence of operation board, and through hole and groove are all rectangular.
After adopting said structure, the utility model compared with prior art, have the following advantages: the special screw rod of baffle plate is fixed on the Abduction arm on vacuum circuit breaker mechanism main shaft, when breaker closing, main shaft turns clockwise 36.6 °, Abduction arm straps is moved baffle plate and is prolonged guide plate and move to operation board, and blocks in operation board and make it can not get to disjunction locked position of coupler.And when vacuum breaker open operation, spindle axis counterclockwise rotates 36.6 °, Abduction arm straps is moved baffle plate and is prolonged guide plate to exiting the operation board blocked, now operation board gets to disjunction locked position of coupler, push rod withstands vacuum circuit-breaker dropout bent plate, pin will block combined floodgate bent plate, VS1 circuit breaker can not be closed a floodgate, when so just realizing breaker closing can not operation isolation and vacuum circuit-breaker separating brake time could " five anti-" the mechanical interlocking functions of operation isolation, and two-way interlocking can be realized, structure is simple, dependability good.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic diagram that fixed vacuum breaker of the present utility model joins the interlock of switch cubicle.
Accompanying drawing 2 is structural representations of guide plate of the present utility model.
Shown in figure, 1, baffle plate, 2, screw rod, 3, connecting lever, 4, guide plate, 5, operation board, 5.1, groove.
Embodiment
Below in conjunction with accompanying drawing, the interlock that fixed vacuum breaker of the present utility model joins switch cubicle is described further.
As shown in Figure 1 and Figure 2, fixed vacuum breaker of the present utility model joins the interlock of switch cubicle, the operation board 5 that it comprises baffle plate 1, is fixed on the guide plate 4 on switch cubicle and is fixed on switch cubicle, the one end of the connecting lever 3 that described one end of baffle plate 1 is connected with the main shaft of vacuum circuit-breaker is hinged, described operation board 5 is provided with the groove 5.1 that the one end for baffle plate 1 embeds, the centre of described guide plate 4 is provided with through hole, the middle part of described baffle plate 1 is positioned at the through hole of guide plate 4, and is provided with gap between the outer wall of baffle plate 1 and the inwall of through hole.
The one end of the connecting lever 3 that described one end of baffle plate 1 is connected with the main shaft of vacuum circuit-breaker is hinged to be referred to, one end of described baffle plate 1 is provided with the first installing hole, one end of described connecting lever 3 is provided with the second installing hole, a screw rod 2 is installed in the first installing hole and the second installing hole, at the last portion nut of screw rod 2.
Groove 5.1 position of the through hole of described guide plate 4 and operation board 5 is corresponding, and through hole and groove 5.1 all rectangular.
Baffle plate is fixed on the Abduction arm on vacuum circuit breaker mechanism main shaft with special screw rod, when breaker closing, main shaft turns clockwise 36.6 °, and Abduction arm straps is moved baffle plate and prolonged guide plate and move to operation board, and blocks in operation board and make it can not get to disjunction locked position of coupler.And when vacuum breaker open operation, spindle axis counterclockwise rotates 36.6 °, Abduction arm straps is moved baffle plate and is prolonged guide plate to exiting the operation board blocked, now operation board gets to disjunction locked position of coupler, push rod withstands vacuum circuit-breaker dropout bent plate, pin will block combined floodgate bent plate, and VS1 circuit breaker can not be closed a floodgate, when so just realizing breaker closing can not operation isolation and vacuum circuit-breaker separating brake time could " five anti-" the mechanical interlocking functions of operation isolation.
