Description
Technical field
The present invention relates to low voltage electrical apparatus technology field, more particularly, what relate to a kind of circuit breaker can "on" position indicating device and the operating mechanism that coordinates with this device.
Background technology
Circuit breaker is as a kind of electric equipment controlling transmission line break-make, and its performance directly affects the safety of downstream electric equipment, and any circuit breaker failure all likely brings huge economic loss or even casualties.Operating mechanism is the execution unit of circuit breaker, is the core of whole circuit breaker, be responsible for providing circuit breaker to divide, energy required for closing operation and to perform point, closing operation.
Circuit breaker at least comprises a pair contact and makes the operating mechanism of contact splitting or integrating, and this operating mechanism can be in multiple different state.In order to the state of display operation mechanism, operating mechanism is also provided with the component of indicating status.The common state instruction of operating mechanism comprises the instruction of splitting or integrating lock and energy storage, releases and can indicate, and wherein when the state indicating member display circuit breaker of circuit breaker is in separating brake and energy storage state, generally can think that circuit breaker is in the state that can close a floodgate.But in fact really not so, when the separating brake snap close in circuit breaker is in non-free position, show that the under-voltage coil of circuit breaker and ETU actuator do not reset or do not remove with the interlocking of drawout chassis, now circuit breaker still can not close a floodgate.Therefore, circuit breaker must meet following three conditions and could close:
1, the necessary energy storage of operating mechanism;
2, circuit breaker must be in disconnection (i.e. separating brake) state;
3, separating brake snap close must be in free position.
Through retrieval, Chinese Patent Application No. 201010201059.9, the applying date is on June 12nd, 2010, and invention and created name is: can "on" position indicating device; This application case discloses one can "on" position indicating device, comprising: main body, indication panel, the first haptic element, the second haptic element, the 3rd haptic element and the 4th haptic element.Indication panel instruction can "on" position or can not "on" position.First haptic element coordinates with the stored energy mechanism of the operating mechanism of circuit breaker.Second haptic element and the 3rd haptic element coordinate with the transmission mechanism of the operating mechanism of circuit breaker.4th haptic element coordinates with the combined floodgate slide block of circuit breaker.When the closing position that the first haptic element is positioned at the energy storage position of circuit breaker, the second haptic element is positioned at circuit breaker and the 3rd haptic element is positioned at the free position of dropout semiaxis of circuit breaker time, indication panel instruction can "on" position, and the 4th haptic element be positioned at the combined floodgate slide block of circuit breaker can closing position; Otherwise indication panel instruction can not "on" position, and the 4th haptic element be positioned at the combined floodgate slide block of circuit breaker can not closing position.This application case to some extent solves instruction circuit breaker can the problem of "on" position, but this application case designs 4 haptic elements coordinates with transmission mechanism, stored energy mechanism and separating brake semiaxis the location status judging circuit breaker respectively, the not only complex structure of state indicating device itself, causes it to manufacture and design costly; , also can correspondingly improve to the complex structure degree of the circuit breaker operation mechanism that this indicating device coordinates, this brings difficulty to the production of whole circuit breaker, assembling meanwhile; In addition, complicated structural design also can cause the corresponding of state indicating device failure rate to be increased, and brings hidden danger to the safety operation of circuit breaker.
