Description
Technical field
The utility model relates to the safety interlock in a kind of ring main unit, belongs to controller switching equipment field, particularly a kind of interlock for breaker main shaft in high-tension switch cabinet and isolated operation axle.
Background technology
Ring main unit is very important electric equipment in electric power system, and the interlock of ring main unit is the important measures ensureing electric equipment and personal safety.Ensureing the safe operation of ring main unit, except strictly pressing except guidelines, also will improve the reliability of ring main unit mechanical interlocking.
In high-tension switch cabinet, the operating sequence of circuit breaker and isolation should be: when switch cubicle is in running status, first by breaker open operation, and then by isolated operation to gate-dividing state.Otherwise order is exactly turn around, first by isolated operation to "on" position, and then by breaker closing.The order of loop conducting and disconnection can not be changed.Therefore just need to install interlock additional between circuit breaker and isolation, make operator can only according to normal running order to complete required movement.The reason done like this is very simple, and because isolation does not possess the ability of drop-out current, if bringing onto load closes isolating switch, isolating switch will be burnt.
Summary of the invention
The utility model is solve circuit breaker and isolate the technical problem that easy misoperation causes potential safety hazard, devise a kind of interlock for breaker main shaft in high-tension switch cabinet and isolated operation axle, structure is simple to operation, the operating sequence of circuit breaker and isolation can only be operated according to the rules, avoid people for misoperation, solve circuit breaker and isolate the technical problem that easy misoperation causes potential safety hazard.
The utility model is the technical scheme realizing goal of the invention employing, for the interlock of breaker main shaft in high-tension switch cabinet and isolated operation axle, be arranged between breaker main shaft and isolated operation axle, key is: the structure of described interlock comprises mechanism's clamping plate, be arranged on the separation retaining sheet above isolated operation axle, breaker switching-on operation button and the combined floodgate catch be arranged on above breaker switching-on operation button, combined floodgate catch rotational positioning is on mechanism's clamping plate, and by the reset tension spring being separately positioned on two ends and the cam that is connected with isolated operation axle, there is rotational freedom, separation retaining sheet has translation freedoms by the horizontal drive mechanism be connected with breaker operator main shaft.
The beneficial effects of the utility model are: 1. by the rotation of main shaft during circuit breaker on/off switch, drive pin-lift arrangement moves, and carries out action, when breaker closing by separation retaining sheet to isolated operation axle, separation retaining sheet blocks the handle hole on isolated operation axle, now cannot disconnecting switch operation; When breaker open operation, now separation retaining sheet does not interfere isolated operation axle, now can disconnecting switch operation; 2. by the operation of isolating switch, by operation isolation operating axis, the cam simultaneously rotated with isolated operation axle stirs the lower connecting lever of combined floodgate catch, and when isolating switch is in open position, combined floodgate catch is interfered switch knob, and circuit breaker now can not close a floodgate; When isolating switch is in closing position, now combined floodgate catch gets out of the way switch knob, and circuit breaker can close a floodgate.This interlocking design substantially increases the fail safe of operation.

Embodiment
A kind of interlock for breaker main shaft in high-tension switch cabinet and isolated operation axle, be arranged between breaker main shaft 1A and isolated operation axle 8, key is: the structure of described interlock comprises mechanism's clamping plate 9, be arranged on the separation retaining sheet 4 above isolated operation axle 8, breaker switching-on operation button 6 and the combined floodgate catch 5 be arranged on above breaker switching-on operation button 6, combined floodgate catch 5 rotational positioning is on mechanism's clamping plate 9, and by the reset tension spring 3 being separately positioned on two ends and the cam 7 that is connected with isolated operation axle 8, there is rotational freedom, separation retaining sheet 4 has translation freedoms by the horizontal drive mechanism be connected with breaker operator main shaft 1A.
The structure of described horizontal drive mechanism comprises: be arranged on the spacing push rod 2 on mechanism's clamping plate 9 of the sector 1 on breaker main shaft 1A, horizontal slip and reseting pressuring spring 2-2, separation retaining sheet 4 is arranged on the end of push rod 2, push rod 2 has the horizontal slip degree of freedom by top with coordinating of sector 1, and separation retaining sheet 4 has translation freedoms by the horizontal slip of push rod 2.
The position limiting structure of described push rod 2 comprises the mounting panel be fixed on mechanism's clamping plate, mounting panel is horizontally provided with one group of location supporting plate 2-3 with slide opening, reseting pressuring spring 2-2 is arranged between adjacent positioned supporting plate, the end of push rod 2 through the slide opening on the supporting plate 2-3 of location and reseting pressuring spring 2-2 horizontal slip spacing.
The top of described push rod 2 is provided with the roller 2-1 coordinated with sector 1.
The shape of described combined floodgate catch 5 is connecting lever types, corner is positioned on mechanism's clamping plate 9 by axis of rotation, the upper connecting lever of combined floodgate catch 5 connects reset tension spring 3 and is arranged on above breaker switching-on operation button 6, and upper connecting lever has rotational freedom by lower connecting lever with coordinating of cam 7.
