The propelling unit not only realizes convenient and fast operation and installation, and also realizes safe and reliable mechanical separation and linkage of a handcart type circuit breaker in working and testing positions.
Description
Technical field
The utility model relates to the indoor high-voltage vacuum circuit breaker in a kind of electrical power distribution system, and is special relevant with the propulsion plant of 10KV and following electric pressure indoor high-voltage vacuum circuit breaker.
Background technology
Power distribution handcart-type indoor high-voltage vacuum circuit breaker has work and two critical positions of test in switch cubicle, circuit breaker only could be realized in these two positions closing a floodgate or not arriving due position fully.Existing 10kV and following electric pressure handcart-type indoor high-voltage vacuum circuit breaker propulsion plant are to sting the clutch that tight leading screw comes realization work and test position by a big bent plate, and the action of big bent plate mainly drives big bent plate action by the motion back and forth of little bent plate.This propulsion plant is unreliable, and the situation that this clutch might occur there is not clutch to fall, and that is to say not arrive corresponding location status fully.If do not arrive the service position, and under the situation that also can close a floodgate this moment, this is less than the regulation contact area with regard to making Mume flower contact with contacting of fixed contact owing to be less than the service position, directly cause the increase of contact resistance, thereby cause that local temperature raises, cause whole switchgear operation troubles, serious even people's interests are caused damage and economic loss.
The utility model content
The utility model is to provide a kind of work of circuit breaker and test position of realizing reliably to distinguish, and guarantees that breaker safe closes a floodgate and shakes 10KV and the following electric pressure indoor high-voltage vacuum circuit breaker propulsion plant that into shakes out switch cubicle.
The indoor AC high voltage vacuum breaker propulsion plant of the utility model is a clutch axle sleeve in succession between leading screw and power shaft, clutch axle sleeve two ends are oblique of two symmetries, core laterally has the elongated slot of symmetry, by being installed on pin in the elongated slot and leading screw and power shaft in succession, clutch axle sleeve core vertically has a groove, be connected with bent plate in the groove, two guide vane end stops are arranged on the bent plate; Clutch axle sleeve, power shaft periphery are provided with the housing of supporting role, and the both sides of the inherent bent plate of housing are provided with spring.
This propulsion plant not only realized convenient in the operation and installation, realized that more handcart type breaker is in the safe and reliable mechanical separation of work and test position and chain.
Description of drawings
Fig. 1 is the structural representation of existing indoor high-voltage vacuum circuit breaker propulsion plant;
Fig. 2 is the structural representation of an embodiment of the utility model indoor high-voltage vacuum circuit breaker propulsion plant.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, leading screw 2, clutch axle sleeve 3, pin 4, power shaft 5, spring 6, guide vane end stop 7, bent plate 8, big bent plate 9, little bent plate 10, guide vane end stop 11, shell
As shown in Figure 2, the utility model indoor high-voltage vacuum circuit breaker propulsion plant is at 4 of leading screw 1 an and power shafts clutch axle sleeve 2 in succession, clutch axle sleeve 2 two ends are oblique of two symmetries, clutch axle sleeve 2 cores laterally have the elongated slot of symmetry, by being installed on pin 3 and leading screw 1 in the elongated slot and power shaft 4 in succession, clutch axle sleeve 2 cores vertically have a groove, are connected with bent plate 7 in the groove, and guide vane end stop 6 and 10 are arranged on the bent plate 7; Clutch axle sleeve 2, power shaft 4 peripheries are provided with the housing 11 of supporting role, and the both sides of housing 11 inherent bent plates 7 are provided with spring 5.
During use, utilize hand crank to shake power shaft 4 clockwise, power shaft 4 drives 2 rotations of clutch axle sleeve, and clutch axle sleeve 2 drives leading screw 1 again and is rotated, and drives circuit breaker and moves to the service position of switch cubicle.Arrive after the service position, at first guide vane end stop 6 is blocked, and drives bent plate 7 and moves backward, and bent plate 7 drives clutch axle sleeve 2 again and moves backward and make its clutch, shake again this moment the input crank to propulsion plant without any the influence in the displacement.When shake out the service position, at first use hand crank to shake power shaft 4 counterclockwise, power shaft 4 drives 2 rotations of clutch axle sleeves, and clutch axle sleeve 2 drives leading screw 1 again and is rotated, and whole propulsion plant drives circuit breaker and moves to the test position of switch cubicle.Arrive after the test position, guide vane end stop 10 is blocked, and drives bent plate 7 and moves backward, and bent plate 7 drives clutch axle sleeve 2 again and also moves backward and make its clutch, and continuing to shake the input crank this moment again will be to propulsion plant without any the influence in the displacement.Realize safe separating by clutch axle sleeve 2 whole shaking in the process of shaking out.In the time of the service position, turn clockwise and arrived clutch position, continuing clockwise choosing dress will be without any effect, when being rotated counterclockwise, clutch axle sleeve 2 will be rotated owing to the pin on the leading screw 3 drives leading screw, when in case the back guide vane end stop is not subjected to active force, clutch axle sleeve 2 will be rebounded by spring 5, is located at position intermediate; Be different on the direction in test position equally, principle is the same.
The indoor high-voltage vacuum circuit breaker propulsion plant that the utility model provides is in the test and two the locational safety and reliability of separating of working, and is simple and easy to do.
