Abstract
The utility model relates to a mechanical interlocking mechanism for a circuit breaker and a three position isolating switch of an N2S gas filled switch cabinet, which comprises a circuit breaker interlocking section and an isolating switch interlocking section which are connected through an interlocking pull rod. The interlocking mechanism plays a role in the mutual limitation of the action between the circuit breaker and the isolating switch so as to achieve the sequence of electrical action. The mechanism has few parts and simple assembly, utilizes the mechanism of a former circuit breaker and the action parts of a former isolating switch mechanism to realize the action, and has few modifications to the former mechanism. After the interlocking mechanism is arranged in the gas filled switch cabinet, the mechanical interlock of the gas filled switch cabinet of the type is perfect, which satisfies the use habit of Chinese users.
Description
One, technical field:
The utility model relates to a kind of mechanical interlocks, particularly discloses a kind of circuit breaker of N2S inflating switch cabinet and the mechanical interlock mechanism of three-positions disconnector.
Two, background technology:
Circuit breaker: can close and close, carry, cut-off the operating loop normal current, also can in official hour, close the switchgear of the overload current that closes, carries, cut-offs regulation.
Isolating switch: when minute position, the insulation distance of requirement up to specification is arranged between contact and significantly disconnect sign; When closing the position, can carry under the regular link condition electric current and in official hour the switch of the electric current under the exceptional condition
Sequence of movement correct between the circuit breaker of inflating switch cabinet and the three-positions disconnector should be: do not allow disconnecting switch operation when circuit breaker is in "on" position, allows disconnecting switch operation when circuit breaker is in gate-dividing state; Just can close circuit breaker after three-positions disconnector operation puts in place, operate not allowing to close circuit breaker when not in place.N2S type inflating switch cabinet does not originally have the mechanical interlocks of circuit breaker and isolating switch, can not realize above-mentioned sequence of movement requirement, cause misoperation easily, such as separately just not operating three-positions disconnector under the situation of circuit breaker, the insulation distance that can cause isolating switch is not enough, starting arc, even burn whole switch cubicle.Cause accident of power supply, cause danger to operation of power networks.
Three, summary of the invention:
The utility model purpose promptly is to overcome between the breaker mechanism of the isolator operating mechanism of this type inflating switch cabinet median generatrix contact cabinet and bus section cabinet to lack the defective that interlocking causes misoperation easily.
The utility model is achieved in that the mechanical interlock mechanism of a kind of circuit breaker and three-positions disconnector, comprises the circuit breaker interlocking part of being made up of link stopper, breaker closing button, circuit breaker main shaft, connecting lever A, connecting lever B; The isolating switch driving mechanism interlocking part of forming by isolating switch position indicating dial, it is characterized in that it also comprises isolating switch interlocking connecting lever A, isolating switch interlocking connecting lever B, inter-agency connecting rod, connecting lever A is by connecting rod and connecting lever B transmission, connecting rod between the working arm moving connecting mechanism of connecting lever B, the arm of inter-agency connecting rod other end and isolating switch interlocking connecting lever A flexibly connects, the arm of another arm of isolating switch interlocking connecting lever A and isolating switch interlocking connecting lever B flexibly connects, another arm and the isolating switch position indicating dial dish edge of isolating switch interlocking connecting lever B are close to engagement, with the action mutual restriction between circuit breaker interlocking part and the isolating switch interlocking part.
This interlocking device comprises circuit breaker interlocking part and isolating switch driving mechanism interlocking part, between connect by the interlocking pull bar, wherein the circuit breaker interlocking part can be divided into the closing locking part of circuit breaker and the separating brake latch portion of isolating switch again, play the mutual restriction of moving between circuit breaker and the isolating switch, to reach the electric sequencing of going up action.Specifically: the isolating switch driving mechanism informs the closing locking part that circuit breaker is interlocked to its residing location status by the interlocking device's action of himself, if do not satisfy the breaker closing condition, then the switch knob of circuit breaker is by locking, and this moment, circuit breaker can not carry out closing operation.The separating brake latch portion of isolating switch interlocking informs the isolating switch interlocking part to the residing location status of circuit breaker in the circuit breaker, if do not satisfy the isolator operation condition, its driving mechanism can not carry out any operation.
The beneficial effects of the utility model are: this constitutional detail quantity is few, and assembling is simple, utilizes the action component in original breaker mechanism and the isolating switch mechanism to realize action, and is little to the change amount of former mechanism.After installing this interlocking device this type inflating switch cabinet mechanical interlocking is perfect, has avoided because the accident of power supply that misoperation causes, has satisfied domestic user's use habit.
Four, description of drawings:
The structure chart that the accompanying drawing breaker mechanism is local and isolating switch mechanism is interlocked
Wherein: 1, block 2, breaker closing button 3, circuit breaker main shaft 4, connecting lever A
5, connecting lever B 6, inter-agency connecting rod 7, isolating switch interlocking connecting lever A
8, isolating switch interlocking connecting lever B 9, isolating switch position indicating dial
Five, embodiment:
With reference to the accompanying drawings, locking between isolating switch position and the breaker closing: pairing three positions of three breach on the isolating switch position indicating dial 9 are respectively combined floodgate, isolation, ground connection, only when these three positions, the roller of isolating switch interlocking connecting lever B8 connecting lever is gone to the breach bottom, this moment, part 8 drive isolating switch interlocking connecting lever A7 actions were delivered to connecting lever B5 by isolating switch interlocking connecting lever A7 connecting rod with this action, drive block 1 release, breaker closing button 2 allows to be pressed at this moment, and circuit breaker can close a floodgate.Otherwise block 1 blocks part 2 when mediating as if part 9, and this moment, part 2 can not be pressed, and circuit breaker can not be closed a floodgate.
Locking between circuit breaker position and the isolating switch: when circuit breaker main shaft 3 as shown during state, when just it is in the separating brake position, connecting lever A4 allows to be left behind by part 6 by coupled four-bar mechanism, also just by the valve mechanism of isolating switch interlocking connecting lever B 8 release isolating switches, this moment, isolating switch mechanism allowed to operate on it by operating grip so simultaneously.Otherwise if circuit breaker is in "on" position, then part 4 akinesias, also valve mechanism that just can not the release isolating switch mechanism, so can't carry out any operation to it.
