Description
Technical field
The utility model relates to a kind of operating mechanism with flexible interlock.
Background technology
At present, the operating mechanism of switch cubicle on the market (especially XGN66 cabinet type) and the main interlocking that adopts solid structure of circuit breaker interlocking, though this interlock method can prevent the generation of misoperation when misoperation takes place, but be easy to cause the damage of interlock, operation reliably causes huge potential risk to device security.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of operating mechanism with flexible interlock is provided, and the flexible interlock of this mechanism is made of machine driving fully, and accurate positioning, anti-misoperation and anti-tamper are effective.
The purpose of this utility model is achieved in that the operating mechanism that the utlity model has flexible interlock, comprise and being arranged on the switch cabinet body, be used to operate the handle hole of control isolating switch mechanism, it is characterized in that: on the described operating mechanism interlocking shaft is installed, described interlocking shaft one end is provided with the rocking arm that blocks that is used to block handle hole when the breaker closing station, described interlocking shaft the other end is fixedly connected with the locking connecting lever, described locking connecting lever end and the terminal flexible, hinged of connecting lever that is arranged on the circuit breaker main shaft.
The above-mentioned rocking arm that blocks is connected with the interlocking shaft vertical fixing.
Above-mentioned locking connecting lever end is connected with extension spring, and the described extension spring other end links with being connected the extension spring screw rod of switching on the piece, and the connecting rod on described switching piece and the connecting lever that is connected circuit breaker main shaft end is flexible, hinged mutually.
Above-mentioned interlocking shaft middle part is provided with the locking torsion spring not reset when interlocking shaft is subjected to twisting resistance, block handle hole so that block rocking arm.
Operation principle of the present utility model: behind breaker open operation, the connecting lever 2 that promptly is installed on the main shaft 1 that opens circuit rotates to the c2 position by the c1 position, the circuit breaker connecting rod 3 that is hinged on the connecting lever 2 drives adapter 4 motions that are enclosed within the other end thereupon, extension spring screw rod 5 on the adapter 4 is fixed on locking connecting lever 7 on the interlocking shaft 8 by extension spring 6 pulling again and overcomes locking torsion spring 10 and make locking connecting lever 7 forward the b2 position to by the b1 position, because locking connecting lever 7 is to be fixed on the interlocking shaft 8, so the rocking arm that blocks on the interlocking shaft 8 just forwards the a2 position to from the a1 position.Handle hole 12 on the switch cubicle operating mechanism 11 is opened at this moment, and operating grip can insert in the handle hole 12 isolating switch is operated.Forget and take off operating grip and when carrying out the closing operation of circuit breaker when operating mechanism is in the maintenance position, the connecting lever 2 that is installed on the main shaft 1 that opens circuit rotates to the c1 position by the c2 position, a circuit breaker connecting rod 3 that is hinged on the connecting lever 2 moves upward, and the rocking arm 14 that blocks that locking torsion spring 10 drives on the interlocking shaft 8 under the effect of self power after losing the pulling force that circuit breaker connecting rod 3 transmission comes turns to the a1 position from the a2 position.Because operating grip does not take off from operating mechanism 11, interlocking shaft 8 is operated the handle retaining between a1 and a2 position.When taking off operating grip, the rocking arm that blocks on the interlocking shaft 8 shelters from mechanism's handle hole rapidly under the effect of locking torsion spring 10, operating grip can't be inserted in mechanism's handle hole before breaker open operation.
The beneficial effects of the utility model are: when circuit breaker was in closing position, the handle hole of operating mechanism was blocked by the last rocking arm that blocks, and operating grip can't be inserted in the operating mechanism handle hole, and misoperation is prevented in starting point.Overhaul the position when mechanism is in, and forget when taking off operating grip,, can not cause the interlocking of circuit breaker and operating mechanism to damage if close circuit breaker.Owing to have above advantage, effectively prevented the generation of misoperation, prolonged the useful life of equipment.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and the specific embodiments
Fig. 1 is the organigram of the utility model embodiment;
Fig. 2 is that the A of Fig. 1 is to view.
Embodiment:
The utlity model has the operating mechanism of flexible interlock, comprise and being arranged on the switch cabinet body 13, be used to operate the handle hole 12 of control isolating switch mechanism, interlocking shaft 8 is installed on the cabinet 13, interlocking shaft 8 one ends be provided with when the breaker open operation station, be used to block handle hole 12 block rocking arm 14, interlocking shaft the other end is fixedly connected with locking connecting lever 7, locking connecting lever 7 ends and the connecting lever 2 terminal flexible, hinged that are arranged on the circuit breaker main shaft 1.
The above-mentioned rocking arm 14 that blocks is connected with interlocking shaft 8 vertical fixing.
Above-mentioned locking connecting lever 7 ends are connected with extension spring 6, and extension spring 6 other ends and the extension spring screw rod 5 that is connected on the adapter 4 link, and the connecting rod 3 on described adapter 4 and the connecting lever 2 that is connected circuit breaker main shaft end is flexible, hinged mutually.
Above-mentioned interlocking shaft 8 middle parts are provided with case spring 10 not reset when interlocking shaft 8 is subjected to twisting resistance, block handle hole 12 so that block rocking arm 14.
The operating mechanism that the utlity model has flexible interlock is when sending electricity.Behind breaker open operation, the connecting lever 2 that promptly is installed on the main shaft 1 that opens circuit rotates to the c2 position by the c1 position, the circuit breaker connecting rod 3 that is hinged on the connecting lever 2 drives adapter 4 motions that are enclosed within the other end thereupon, extension spring screw rod 5 on the adapter 4 is fixed on locking connecting lever 7 on the interlocking shaft 8 by extension spring 6 pulling again and overcomes locking torsion spring 10 and forward the b2 position to by the b1 position, because locking connecting lever 7 is to be fixed on the interlocking shaft 8, so the rocking arm 14 that blocks on the interlocking shaft 8 just forwards the a2 position to from the a1 position.Handle hole 12 on the switch cubicle operating mechanism 11 is opened at this moment, and operating grip can insert in the handle hole 11 isolating switch is operated.Forget and take off operating grip and when carrying out the closing operation of circuit breaker when operating mechanism is in the maintenance position, the connecting lever 2 that is installed on the main shaft 1 that opens circuit rotates to the c1 position by the c2 position, a circuit breaker connecting rod 3 that is hinged on the connecting lever 2 moves upward, and the rocking arm 14 that blocks that locking torsion spring 10 drives on the interlocking shaft 8 under the effect of self power after losing the pulling force that circuit breaker connecting rod 3 transmission comes turns to the a1 position from the a2 position.Because operating grip does not take off from operating mechanism 11, interlocking shaft 8 is operated the handle retaining between a1 and a2 position.When taking off operating grip, the rocking arm 14 that blocks on the interlocking shaft 8 shelters from mechanism's handle hole rapidly under the effect of locking torsion spring 10, operating grip can't be inserted in mechanism's handle hole before breaker open operation.
