Specific implementation mode
To carry out the specific implementation mode of the interlocking mechanism of breaker and disconnecting switch in the present invention in conjunction with attached drawing
Explanation.
As shown in Figures 1 to 4, it is the embodiment of the interlocking mechanism of breaker and disconnecting switch in the present invention：By open circuit
In the equipment body that device 2 and disconnecting switch 8 form, disconnecting switch 8 is directly connect by holder with breaker 2, in order to ensure to set
Standby is safe to use, and the interlocking mechanism of breaker and disconnecting switch is provided between breaker 2 and disconnecting switch 8.Breaker 2
It is equipped with divide-shut brake and indicates that axis 21, technical staff indicate axis 21 intuitively to judge the switching on and off of breaker 2 by divide-shut brake
Situation, is accordingly provided with disconnecting switch shaft 81 in disconnecting switch 8, technical staff by rotate disconnecting switch shaft 81 come
Realize the switching on and off of disconnecting switch 8, and breaker 2 and the interlocking mechanism of disconnecting switch 8 further include being fixed at breaker 2
Divide-shut brake instruction axis 21 on interlocking swing arm 1, further include in the isolation shaft for be fixed on disconnecting switch 8 with isolation shaft pendulum
Dynamic stop block 10 interlocks and is hinged with interlocking bar 3 in swing arm 1, limiting plate is additionally provided in interlocking mechanism, is opened on limiting plate
Equipped with the bar limit hole 5 for passing through for interlocking bar 3 and stretching for interlocking bar 3 when interlocking swing arm and swinging, bar limit hole 5
Size than interlock bar 3 radial dimension it is somewhat larger.The interlocking bar 3 is in combined floodgate shape in divide-shut brake instruction axis 21
It is stretched out when state with the block position of the swaying direction both sides block cooperation with stop block 10, also has and be in divide-shut brake instruction axis 21
It is retracted when gate-dividing state to avoid the solution lock-bit of the stop block 10.
The setting interlocking swing arm 1 on divide-shut brake instruction axis 21, interlocking swing arm 1 can indicate the rotation of axis 21 with divide-shut brake and
Action, and interlock bar 3 and be directly hinged in interlocking swing arm 1, when interlocking swing arm 1 drives interlocking bar 3 to act, make linkage block
Significantly beat will not occur for bar 3, but have the reciprocating action of slightly smaller angle beat.Also connect in the lower section of interlocking swing arm 1
It is connected to the pointer for being used to indicate 2 switching on and off situation of breaker.Be provided in disconnecting switch 8 with breaker it is positioned opposite every
From chassis 7, disconnecting switch 8 be fixed on isolation chassis 7 on, while isolation chassis 7 on be provided with make with interlocking swing arm 1 coordinate
Using the otic placode 4 as limiting plate, offered on otic placode 4 for the bar limit hole 5 that wears of interlocking bar 3, and interlock bar 3 with
The position that bar limit hole 5 coordinates is cylinder.Bar 3 is interlocked in the case where being indicated that axis 21 and interlocking swing arm 1 drive by divide-shut brake,
Interlocking bar 3 is realized indicates that the linearly operating between axis 21 and disconnecting switch shaft 81, interlocking bar 3 move in divide-shut brake
Straight line is exactly to interlock bar 3 axis of itself.The interlocking machine hingedly formed by branched interlocking bar 3 in compared to the prior art
Structure, interlocking bar 3 only exist the forms of motion along straight line or approximate straight line motion, will not generate clamping stagnation during interlocking,
It ensure that breaker 2 and 8 accuracy of action of disconnecting switch, and the stability of interlocking.
In addition, being provided with end that can be in interlocking 3 action process of bar with interlocking bar 3 in disconnecting switch shaft 81
The stop block 10 of head cooperation, preferably fanning strip.Stop block 10 is connected directly between on the peripheral surface of disconnecting switch shaft 81, and energy
It is enough to be rotated together with disconnecting switch shaft 81.The block with the end block cooperation of interlocking bar 3 is provided on stop block 10
Face.In addition, corresponding combined floodgate spacer pin 9 and dividing being provided with the when of be in switching on and off state with disconnecting switch 8 on chassis 7 is isolated
Lock spacer pin 6.The inner concave on stop block 10 is arranged can equally be coordinated with combined floodgate spacer pin 9 and separating brake spacer pin 6,
Improve the accuracy of action of disconnecting switch shaft 81.
As shown in Fig. 2, being breaker closing, interdigitation when disconnecting switch is closed a floodgate, breaker is in technical staff at this time
Operation under, divide-shut brake indicates that axis 21 rotates, and the pointer on divide-shut brake instruction axis 21 has been directed toward mark combined floodgate on-board the circuit breaker
Position, divide-shut brake indicate that axis 21 drives interlocking swing arm 1 to rotate, and interlocking swing arm 1 drives interlocking bar 3 to act, and is arranged and is keeping apart
The otic placode 4 for closing side is oriented to the action of linkage block bar 3,5 inner wall of bar limit hole in otic placode 4 and interlocking bar 3
Peripheral surface is oriented to cooperation, and interlocking bar 3 is made to be moved along the disconnecting switch side that is axially facing of itself, forms direct acting interlocking
Forms of motion, action is smooth, does not have clamping stagnation sense, and disconnecting switch shaft 81 turns to closing position at this time, in disconnecting switch shaft 81
Stop block 10 respectively with combined floodgate spacer pin 9 and interlock the end of bar 3 and coordinate, and can not rotate, to realize in open circuit
When device is in combined floodgate, disconnecting switch cannot generate the technology requirement of splitting or integrating lock action.
As shown in figure 3, be breaker open operation, interdigitation when disconnecting switch separating brake, at this time technical staff rotate division
Lock instruction axis 21 makes breaker be in gate-dividing state, and divide-shut brake instruction axis 21 drives interlocking bar 3 to be retracted from disconnecting switch side,
Stop block 10 in disconnecting switch shaft 81 is no longer influenced by the limitation of interlocking bar 3, and disconnecting switch shaft 81 is enable freely to turn
It is dynamic, to enable disconnecting switch freely to complete the action of splitting or integrating lock.
As shown in figure 4, being breaker closing, interdigitation when disconnecting switch separating brake is different from situation shown in FIG. 1
It is that interlocking bar 3 limits the action of disconnecting switch shaft 81 with separating brake spacer pin 6 together, to make disconnecting switch in open circuit
Device cannot achieve the action of splitting or integrating lock in the case of closing a floodgate.
Above-described specific implementation mode, to the present invention goal of the invention, technical solution and advantageous effect carried out into
One step is described in detail, it should be understood that the foregoing is merely the specific implementation mode of the present invention, is not used to limit this
The protection domain of invention, every any modification, equivalent substitution, improvement and etc. within the spirit and principles in the present invention, done,
It should be included within protection scope of the present invention.
