The invention is provided with the frame type circuit breaker which can be operated by remote control.
Description
Technical field
The invention belongs to the structure-design technique field of circuit breaker, especially a kind of resetting device of frame-type circuit breaker.
Background technology
When the tripping operation fault takes place in frame-type circuit breaker, in order to prevent under the situation that fault is not got rid of a mechanical chain mechanism and the resetting device that interlocking gear is resetted to be set usually on circuit breaker by false switching.
Fig. 1 is a kind of structural representation of resetting device of traditional frame-type circuit breaker, has shown the resetting device of traditional frame-type circuit breaker; This resetting device comprises housing (1), the push rod that resets (2), be used to the push rod that resets (2) self resets the spring of elastic force (3) is provided, and said spring (3) is arranged on the top of the push rod that resets; During use, manually press this push rod that resets, the push rod that resets moves downward, and the pushing block of the push rod bottom that resets promotes the connecting rod in the external interlocking gear, thereby triggers release mechanism, makes this frame-type circuit breaker to close a floodgate.The shortcoming of the resetting device of this kind frame-type circuit breaker is to rely on on-the-spot manual operations, can't carry out remote control operation.
In addition, after the circuit breaker failure tripping operation, the core component intelligent controller of circuit breaker also is in the fault trip state.It is distributed on through this locality demonstration and communication network and is in the fault trip state on this node, under this occasion, if controller fails to reset, can not close a floodgate.
Summary of the invention
The resetting device that the purpose of this invention is to provide a kind of frame-type circuit breaker of remote controlled operation.
The technical scheme that realizes the object of the invention is: a kind of resetting device of frame-type circuit breaker, this resetting device comprise housing, the push rod that resets, be used to the push rod self that resets and reset the spring of elastic force is provided; Also be provided with first forced section on the said push rod that resets, also be provided with in the said housing and be used for driving the motor-operating mechanism that the push rod that resets moves through first forced section.
In the technique scheme, said motor-operating mechanism is the electromagnetic type actuating mechanism that is fixed on the housing, and said electromagnetic type actuating mechanism comprises coil that is fixed on the housing and the moving iron core that is arranged in coil.
In the technique scheme, the said push rod that resets is arranged on the below of electromagnetic type actuating mechanism, and said first forced section is arranged on the top of the push rod that resets.
In the technique scheme, the outer press handle that forms of housing is stretched out at the top of the said push rod that resets.
In the technique scheme, also be provided with second forced section of transverse projections on the said push rod that resets, said resetting device also comprises an optical-electrical converter that is fixed on the housing and can be triggered by said second forced section.
The present invention has positive effect: (1) the present invention drives the motor-operating mechanism (4) that the push rod that resets moves through adding; Owing to can control this motor-operating mechanism through correspondent control circuits; Thereby can replace traditional on-site manual to press the push rod that resets, thereby remote control operation is come true.(2) the present invention is through adopting the push rod and motor-operating mechanism is set in corresponding position of resetting of different structure, thereby makes the present invention can electronic Long-distance Control, but also execute-in-place has the wider advantage of adaptability.(3) the present invention is employed on the said push rod that resets second forced section is set; After in housing, adding optical-electrical converter; When the push rod that resets drives external interlocking gear, also trigger optical-electrical converter, thereby to signal of telecommunication of correspondent control circuits input; Thereby can make the core component intelligent controller reset, combined floodgate is carried out smoothly from being in the fault trip state; Mechanical type resets and carries out simultaneously with electronic reset like this, makes its service behaviour more reliable.

Embodiment
(embodiment 1)
Fig. 2 is first kind of structural representation of the present invention, has shown first kind of execution mode of the present invention.
Present embodiment is a kind of resetting device of frame-type circuit breaker, and this resetting device comprises housing 1, the push rod 2 that resets, be used to the push rod 2 that resets and self reset the spring of elastic force 3 is provided; Also be provided with first forced section 21 on the said push rod 2 that resets, also be provided with in the said housing 1 and be used for driving the motor-operating mechanism 4 that the push rod 2 that resets moves through first forced section 21.Said motor-operating mechanism 4 is the electromagnetic type actuating mechanisms that are fixed on the housing 1, and said electromagnetic type actuating mechanism comprises the coil that is fixed on the housing 1 and is arranged in moving unshakable in one's determination 41 of coil.The said push rod 2 that resets is arranged on the below of electromagnetic type actuating mechanism, and said first forced section 21 is arranged on the top of the push rod 2 that resets.
Present embodiment drives the motor-operating mechanism 4 that the push rod that resets moves through adding, owing to can control this motor-operating mechanism through correspondent control circuits, thus can replace traditional on-site manual to press the push rod that resets, thus remote control operation is come true.
(embodiment 2)
Fig. 3 is second kind of structural representation of the present invention, has shown second kind of execution mode of the present invention.
Present embodiment and embodiment 1 are basic identical, and difference is: the said push rod 2 that resets is longer, and the housing 1 outer press handle 23 that forms is stretched out at its top.Said motor-operating mechanism 4 no longer be positioned at the push rod 2 that resets directly over, but be positioned at the one of which side, first stressed member 21 of the said push rod 2 that resets is the washers along push rod 2 transverse projections that reset; Such structure makes present embodiment get final product electronic remote operation, but also on-site manual operation.
