Technical field
This utility model relates to power transmission technical field, is specifically related to a kind of outdoor distribution low-voltage protection switch-box.
Background technology
Out of doors in distribute-electricity transformer district interruption maintenance process, the circuit-breaker switching on-off plectrum that electric power maintenance personnel can often operate in distribution low-voltage protection switch-box excises or recovers customer charge.Traditional mode of operation is that the hand-held insulating bar of operating personnel directly operates exposed connecting rod outside low-voltage switch box tank wall, connecting rod stretches in the casing of low-voltage switch box and is connected with throw rod, the hand-held insulating bar of electric power maintenance personnel makes link rotatable, thus the throw rod interlocked in low-voltage switch box rotates, and then implement the cut-out to circuit-breaker switching on-off plectrum or recovery operation.But outdoor distribution low-voltage protection switch-box is completely exposed in the external world on the one hand, it is easy to the link position place corrosion so that connecting rod or throw rod, fracture, and the operation of pulling of throw rod cannot be realized, on the other hand, the connection of throw rod and circuit-breaker switching on-off plectrum is that the bar hole by being arranged on throw rod realizes, due to pull circuit-breaker switching on-off plectrum to pull moment bigger, and it is comparatively frequent to pull operation, thus easily lead to the bar hole bending on throw rod, deform and cannot realize and circuit-breaker switching on-off plectrum contact, and then the purpose of chopper deciliter cannot be realized.
Utility model content
The purpose of this utility model is: provide the outdoor distribution low-voltage protection switch-box that the clutch plectrum deciliter of chopper is operated by a kind of effective enforcement.
For achieving the above object; the technical solution adopted in the utility model is: a kind of outdoor distribution low-voltage protection switch-box; including the chopper in switch-box casing and switch-box casing; the clutch plectrum of chopper is connected with driving lever; driving lever is hinged with the eccentric shaft of setting on driving wheel; described driving wheel is connected with motor, and motor drives driving wheel to rotate.
Compared with prior art, the technique effect that this utility model possesses is: motor drives in the process that driving wheel rotates, so that driving lever presents the attitude of swing, driving lever is connected with the clutch plectrum of chopper, driving lever is in the process swung, thus implementing deciliter operation of the clutch plectrum to chopper, electronic operating mechanism is adopted to realize the switching manipulation of chopper of distribution low-voltage switch-box, motor-operating mechanism can be directly disposed in the casing of low-voltage switch box, it can be avoided that the erosion that rainwater is to said structure, above-mentioned motor-operating mechanism can implement deciliter operation of the clutch plectrum to chopper effectively.

Detailed description of the invention
In conjunction with Fig. 1 to Fig. 5, the utility model is further described
A kind of outdoor distribution low-voltage protection switch-box; including the chopper 20 in switch-box casing 10 and switch-box casing 10; the clutch plectrum of chopper 20 is connected with driving lever 30; driving lever 30 is hinged with the eccentric shaft 411 of setting on driving wheel 41; described driving wheel 41 is connected with motor 42, and motor 42 drives driving wheel 41 to rotate.
Abandon in prior art, adopt tommy bar, the drawback that the complex attachment structure such as connecting rod is brought, adopt the mode that driving lever 30 is directly connected with the clutch plectrum of chopper 20, the rotation utilizing motor 42 drives driving wheel 41 to rotate, and then interlock the swing of driving lever 30, the swing of driving lever 30 the enforcement deciliter operation to the clutch plectrum of chopper 20, electronic operating mechanism is adopted to realize the switching manipulation of chopper 20 of distribution low-voltage switch-box, motor-operating mechanism can be directly disposed in low tension switch box body 10, it can be avoided that the erosion that rainwater is to said structure, it is big that above-mentioned motor-operating mechanism has mechanical force moment, reliability is high, corrosion-resistant, put the features such as distortion, thoroughly solve the mechanical transmission mechanism of outdoor distribution low-voltage protection switch-box because of corrosion fracture, the factors such as connecting rod twist and cannot effectively implement the problem to chopper 20 deciliters.
Further, described driving lever 30 is provided with the clutch plectrum composition snap-fit engagement of bayonet socket 31 and chopper 20.This bayonet socket 31 is when the clutch plectrum with chopper 20 constitutes snap-fit engagement, and driving lever 30 is when reciprocally swinging, thus implementing the clutch operation to chopper 20.
For convenience of the mounting arrangements of above-mentioned motor-operating mechanism, the outer panel face of described chopper 20 is provided with installing plate 50, and described driving wheel 41 and driving lever 30 are arranged on the interior plate face of installing plate 50.
