Abstract
The present invention relates to a circuit breaker tripping actuating device, which is composed of a fixing support, a driving plate and a spring, wherein the driving plate is movably fixed on the fixing support, one end of the spring is fixed on the outer wall of the fixing support, the other end of the spring is fixed on one end of the driving plate in the fixing support, the other end of the driving plate is provided with a driving block, and the driving block contacts a tripping half shaft of the circuit breaker. The present invention is characterized in that the head part of one end of the driving plate in the fixing support is provided with a control plate of which the front end is provided with a hook, the hook of the control plate is hooked on a pin shaft, the pin shaft is fixed on the fixing support, one end of the pin shaft is sheathed in a torsion spring, and a notch is arranged on the pin shaft. Because the present invention adopts a low powered permanent magnetic coil output shaft to control the movements of the control plate, the energy of an opening coil can be amplified, and accordingly, the purpose of opening a switch can be achieved reliably.
Description
Technical field
The invention belongs to tripping actuating device in a kind of panel switches cabinet, particularly a kind of circuit breaker tripping actuating device.
Background technology
In present most of distribution network systems; the power supply of employed power distribution cabinet second protection is to take from bus by voltage transformer, in case the bus pressure drop is big or voltage transformer breaks down, second protection can't action message; circuit breaker can't trip, and does not have protective effect.If adopt reliable DC power supply, cost of equipment is higher, and maintenance is bigger.
Summary of the invention
Purpose of the present invention provides a kind of employing passive protection, even when busbar short-circuit, under the very big situation of pressure drop, the circuit breaker tripping actuating device that circuit breaker can reliably trip is to overcome above-mentioned deficiency.
To achieve these goals, the present invention is by fixed support, drive plate and spring constitute, be characterized in: the drive plate activity is fixed on the fixed support, one end of spring is fixed on the fixed support outer wall, the other end of spring is fixed on the end of drive plate in fixed support, there is a drive block another termination of drive plate, drive block contacts with the dropout semiaxis of circuit breaker, the head of the end of drive plate in fixed support has the control board of a front end buckle, the hook of control board is hooked on the bearing pin, bearing pin is fixed on the fixed support, and an end of bearing pin is with a torsion spring, and bearing pin is provided with a breach.
Also be fixed with a permanent magnetism coil in the said fixing support, the bearing pin in the fixed support is provided with a push rod, and the output shaft of permanent magnetism coil contacts with push rod on the bearing pin, and the coil of relay is connected with the signal of the output of second protection.
Because the present invention has adopted the mode of no external power supply, avoided because the interference that the power supply instability is brought to the protection operate as normal.The present invention can amplify the energy of switching winding owing to adopt low power permanent magnetism coil output shaft controlling and driving plate to move, thereby reaches the purpose of reliable separating brake.

Embodiment
Further specify the present invention below in conjunction with accompanying drawing.
The present invention is in the state that spacing point has still been crossed in energy storage when circuit breaker 7 is in gate-dividing state, energy storage of the present invention is to finish by the divide-shut brake dropout semiaxis 71 of circuit breaker 7.When circuit breaker 7 closes a floodgate, the divide-shut brake dropout semiaxis 71 of circuit breaker travels forward, and contacts drive block 22 of the present invention, and drive plate 2 of the present invention is travelled forward simultaneously, head control board 21 until drive plate 2 is hooked on the bearing pin 4, and the present invention's this moment reaches energy storage, prepares the state of separating brake.When second protection provides the semaphore request separating brake; relay 5 coil motion; the output shaft 51 of relay 5 is released; promote the push rod 41 on the bearing pin 4, make bearing pin 4 rotations, when bearing pin 4 rotates to its breach 42 when touching the hook of head control board 21 of drive plate 2; control board 21 breaks away from bearing pin 4; this moment, drive plate 2 was extrapolated owing to the effect of spring 3, and the divide-shut brake dropout semiaxis 71 that makes drive block 22 promote circuit breakers 7 makes breaker open operation.In circuit breaker 7 separating brake processes, the divide-shut brake dropout semiaxis 71 of circuit breaker 7 drives drive plate 2 motion backward simultaneously, makes drive plate 2 of the present invention be in the energy storage state, waits for sub-gate signal next time.
The content that is not described in detail in this specification belongs to this area professional and technical personnel's known prior art.
