Abstract
The invention relates to an electric operating mechanism for a circuit breaker with separating brake protection. The circuit breaker comprises a shell, wherein a rotating shaft, a motor and a gear reducing mechanism are arranged in the shell; a sector gear is arranged on the rotating shaft, and is connected with the output shaft of the motor through the gear reducing mechanism; The electric operating mechanism is characterized by further comprising an overturning plate, the overturning plate is 7-shaped, and the bending part of the overturning part is hinged to the inner wall of the shell together. a sector groove is formed in the rotating shaft. When the overturning plate turns over towards the outside of the shell along the hinged point, one end of the overturning plate stretches out of the shell, a ring latch hole is formed in the end, stretching out of the shell, of the overturning plate, and the axis of the ring latch hole is parallel to the axis of the hinged point of the overturning plate; when the ring latch hole is completely positioned outside the shell, the end, positioned inside the shell, of the overturning plate stretches into the sector groove of the rotating shaft; when the overturning plate turns over towards the inside of the shell along the hinged point, the end, positioned inside the shell, of the overturning plate is separated from the sector groove of the rotating shaft. The electric operating mechanism is free of potential safety hazards during separating brake protection, and is convenient to use.
Description
Technical field
The present invention relates to a kind of electric equipment, be specifically and the matching used circuit breaker motor-operating mechanism with separating brake protection of circuit breaker.
Background technology
In electric utility, all know, circuit breaker, in the time that separating brake overhauls, for maintainer's safety, prevents that circuit breaker from closing a floodgate because of the effect of external force, and circuit breaker all can support the use the circuit breaker motor-operating mechanism with separating brake protection conventionally.
At present, the circuit breaker with separating brake protection adopting in industry comprises rolling disc with motor-operating mechanism, slide plate and a semi-circular teeth dish, described rolling disc one side arranges one handle, described rolling disc opposite side extension arranges a rotating shaft, in described rotating shaft, offer a holddown groove, described semicircle fluted disc embeds in holddown groove and is socketed on same axis with rotation seat, on described rolling disc, offer a breach, one end of described slide plate is provided with promotion button, on described promotion button, offer a padlock hole, the other end of described slide plate is provided with snap fit, in the time that slide plate moves backward, snap fit is buckled in the breach of rolling disc.Traditional circuit breaker with separating brake protection with motor-operating mechanism carrying out separating brake while protecting; first utilize promotion button that slide plate is outwards slided; snap fit on slide plate is anchored in the breach in rotating shaft; then on padlock hole, hang up lock; anti-limited slip plate is return, thereby guarantees that circuit breaker can not close a floodgate because of the effect of external force.Because this motor-operating mechanism is to adopt the slide plate slide mechanism that coordinates with chute to limit the rotation of rotating shaft; in order not affect the overall dimensions of this motor-operating mechanism; it is too thick that slide plate can not do; therefore the intensity of slide plate self is often lower; itself or padlock are in the time receiving external force collision; easily cause the fracture of slide plate, lose protection effect, in the time carrying out separating brake protection, have potential safety hazard.And when mounted, circuit breaker and motor-operating mechanism are to be all embedded in metope conventionally, be in motor-operating mechanism, to have the one side of slide plate conventionally all flush with the panel of metope or power distributing cabinet or slightly give prominence to, like this, the slip of slide plate and the position of padlock are easy to interfere with the panel of metope or power distributing cabinet, use inconvenient.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of circuit breaker motor-operating mechanism with separating brake protection, and this motor-operating mechanism does not exist potential safety hazard in the time carrying out separating brake protection, easy to use.
For addressing the above problem, provide following technical scheme:
Circuit breaker with separating brake protection of the present invention comprises housing with motor-operating mechanism, has rotating shaft, motor and gear reduction in housing.The outside of described rotating shaft is coaxially fixed with sector gear, between the output shaft of sector gear and motor, is connected by gear reduction.Be characterized in also comprising turnover panel, this turnover panel is " 7 " font, and its kink and inner walls are hinged.Described rotating shaft has scalloped recess along the outer wall at its axial middle part.In the time that turnover panel stirs along pin joint to hull outside, one end of turnover panel reaches outside housing, reach on that end turnover panel outside housing and have padlock hole, the axis in this padlock hole is parallel with the axis of turnover panel pin joint, in the time that padlock hole is positioned at outside housing completely, that one end that turnover panel is positioned at housing extend into the scalloped recess of rotating shaft, and when turnover panel is when along pin joint to housing, inner side is stirred, that one end that turnover panel is arranged in housing departs from from the scalloped recess of rotating shaft.
Further improvement of the present invention scheme is limited location groove on the sidewall of described housing, and while making turnover panel stir extreme position to housing inner side, turnover panel has the outside of that one end in padlock hole to enter in this stopper slot.When this structure makes turnover panel stir to housing inner side, can not enter completely in housing, its padlock end can not interfered with sector gear, is also conducive to again carry out separating brake protection action simultaneously.
Take above scheme, have the following advantages:
Because the circuit breaker with separating brake protection of the present invention is " 7 " font with the turnover panel of motor-operating mechanism, its kink and inner walls are hinged, rotating shaft has scalloped recess along the outer wall at its axial middle part, in the time that turnover panel stirs along pin joint to hull outside, one end of turnover panel reaches outside housing, reach on that end turnover panel outside housing and have padlock hole, the axis in this padlock hole is parallel with the axis of turnover panel pin joint, in the time that padlock hole is positioned at outside housing completely, that one end that turnover panel is positioned at housing extend into the scalloped recess of rotating shaft, when turnover panel along pin joint to housing inner side while stirring, that one end that turnover panel is arranged in housing departs from from the scalloped recess of rotating shaft.So in the time of needs padlock, turnover panel is stirred to hull outside along the pin joint of itself and housing, making has that one end in padlock hole to reach outside housing on turnover panel, then hangs up lock on padlock hole.The thickness of this motor-operating mechanism flap is unrestricted, can easier adopt the method for increase turnover panel thickness to strengthen the intensity of turnover panel, makes turnover panel be difficult for producing fracture, and then makes this motor-operating mechanism in the time carrying out separating brake protection, not have potential safety hazard.Meanwhile, the turnover panel of this separating brake protection mechanism is to stir to the hull outside of its place face, the restriction that its action can not be subject to installing metope or power distributing cabinet panel, and stirring and padlock processing ease of turnover panel, easy to use.
Brief description of the drawings
