Technical field
The utility model relates to the interlocking device that is pressed in a kind of in the complete equipment as earthed switch and circuit breaker, specifically a kind of Medium Voltage Switchgear earthed switch and circuit breaker interlocking device.
Background technology
Be pressed in the complete equipment interlocking between the circuit breaker and framework in traditional mainly on platform, but the situation (being that the violence operation damages interlocking) that misoperation can occur, under the state that earthed switch closes a floodgate, the words that the circuit breaker mistake are pushed into the service position can cause serious accident, therefore need a kind of can the assurance completely after earthed switch closes a floodgate, circuit breaker just can't shake to the service position from test position, thereby ensures the interlocking device of maintainer's personal safety.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of Medium Voltage Switchgear earthed switch and circuit breaker interlocking device of simple to operation, the personal safety that can ensure the maintainer that reliability is high.
In order to solve the problems of the technologies described above, Medium Voltage Switchgear earthed switch of the present utility model and circuit breaker interlocking device, comprise the platform that is arranged on the breaker assembly below, platform is provided with a rectangular notch, the inboard of platform is provided with an interlocking arm-tie that has L shaped notch that can move horizontally along mesa sidewalls, be provided with an interlocking bolt that can move along the track of L shaped notch in the L shaped notch of interlocking arm-tie, the interlocking bolt is connected with the interlocking latch of breaker assembly below; One side of described interlocking arm-tie is provided with an earthed switch main shaft, and earthed switch interlocking connecting lever is installed on the earthed switch main shaft, earthed switch interlocking connecting lever be provided with a spacing edge-cut; Also comprise a platform interlocking pull bar that is used for the transmission of power of earthed switch main shaft is given the interlocking arm-tie, one end of platform interlocking pull bar is stuck in the draw-in groove of interlocking arm-tie, and the other end of platform interlocking pull bar optionally is pressed on the earthed switch interlocking connecting lever or is positioned at spacing edge-cut; The oblique offside of the draw-in groove on the interlocking arm-tie is provided with a spring, and the other end of spring is connected on the sidewall of platform, and when platform interlocking pull bar was positioned at spacing edge-cut, the elongated slot in the L shaped notch of the rectangular notch that arranges on the platform and interlocking arm-tie coincided.
After adopting above-mentioned structure, because the interlocking arm-tie that has L shaped notch that arranges, be provided with the interlocking bolt that is connected with interlocking latch in the L shaped notch of interlocking arm-tie, the interlocking arm-tie is by a platform interlocking pull bar and earthed switch main shaft transferring power, arrange thus when earthed switch and be in gate-dividing state, circuit breaker just can shake to the service position from test position, can't the operational grounding switch, have only when circuit breaker is retracted into test position by the service position, can the operational grounding switch, and after earthed switch closed a floodgate, circuit breaker just can't shake to the service position from test position, it is simple to operation, the reliability height, and can ensure maintainer's personal safety.

Embodiment
Below in conjunction with the drawings and specific embodiments, Medium Voltage Switchgear earthed switch of the present utility model and circuit breaker interlocking device are described in further detail.
As shown in the figure, Medium Voltage Switchgear earthed switch of the present utility model and circuit breaker interlocking device, comprise the platform 1 that is arranged on the breaker assembly below, platform 1 is provided with a rectangular notch, the inboard of platform 1 is provided with an interlocking arm-tie 2 that has L shaped notch that can move horizontally along mesa sidewalls, be provided with an interlocking bolt 3 that can move along the track of L shaped notch in the L shaped notch of interlocking arm-tie 2, interlocking bolt 3 is connected with the interlocking latch of breaker assembly below; One side of described interlocking arm-tie 2 is provided with an earthed switch main shaft 4, and earthed switch interlocking connecting lever 5 is installed on the earthed switch main shaft 4, earthed switch interlocking connecting lever 5 be provided with a spacing edge-cut 8; Also comprise a platform interlocking pull bar 6 that is used for the transmission of power of earthed switch main shaft 4 is given interlocking arm-tie 2, one end of platform interlocking pull bar 6 is stuck in the draw-in groove of interlocking arm-tie 2, and the other end of platform interlocking pull bar 6 is pressed on the earthed switch interlocking connecting lever 5 according to the difference of earthed switch main shaft 4 states or is positioned at spacing edge-cut 8; The oblique offside of the draw-in groove on the interlocking arm-tie 2 is provided with a spring 7, the other end of spring 7 is connected on the sidewall of platform 1, when platform interlocking pull bar 6 was positioned at spacing edge-cut 8, the elongated slot in the L shaped notch of the rectangular notch that arranges on the platform 1 and interlocking arm-tie 2 coincided.
Its operation principle is as follows:
When earthed switch closes a floodgate, earthed switch interlocking connecting lever 5 is along with earthed switch main shaft 4 rotates, drive platform interlocking pull bar 6 simultaneously and turn over equal angular, because platform interlocking pull bar 6 is stuck in the draw-in groove of interlocking arm-tie 2, platform interlocking pull bar 6 drives interlocking bolt 3 by spring 7 and moves to the left, at this moment, interlocking bolt 3 drops in the L shaped notch of interlocking arm-tie 2, and interlocking bolt 3 is to drive into by the platform inboard that the interlocking latch of leading screw and breaker assembly below forms interlocking, because interlocking bolt 3 is stuck in the L shaped notch of interlocking arm-tie 2, can't move forward, like this, just can guarantee that circuit breaker when test position, can't be shaken to the service position by test position;
When earthed switch transfers separating brake to by combined floodgate, earthed switch interlocking connecting lever 5 rotates with the earthed switch main shaft, this moment, platform interlocking pull bar 6 was owing to lost the supporting role of earthed switch interlocking connecting lever 5, under the effect of spring 7, move to the right (resetting), fall in the spacing edge-cut 8 on the tieback ground switch interlocking connecting lever 5, the rectangular notch that arranges on elongated slot in the L shaped notch of interlocking arm-tie 2 and the platform 1 overlaps, at this moment, interlocking bolt 3 just can move forward along with the interlocking latch of breaker assembly below, and circuit breaker just can move to the service position from test position like this; Earthed switch deciliter indicator board is along with platform interlocking pull bar 6 turns over equal angular together simultaneously, at circuit breaker during still in test position, earthed switch deciliter indicator board can drive interlocking bolts 3 move left and right by interlock pull bar 6 of platform, when circuit breaker shakes to the service position from test position, interlocking bolt 3 moves forward and backward in can only the short groove in the L shaped notch of interlocking arm-tie 2 and can not move left and right, this moment, earthed switch deciliter indicator board just can't be opened, also just can't the operational grounding switch.
By above-mentioned operation principle as can be seen, when earthed switch is in gate-dividing state, circuit breaker just can shake to the service position from test position, this moment, earthed switch position indicator board was also by locked, can't the operational grounding switch, have only when circuit breaker is retracted into test position by the service position, earthed switch just position indication sheet material can rotate, this moment can the operational grounding switch, and after earthed switch closes a floodgate, circuit breaker just can't shake to the service position from test position, so just can guarantee maintainer's safety.
