Abstract
An electric operating mechanism of hv switch-disconnector, the utility model relates to an electric operating mechanism of hv switch-disconnector, which comprises a case, a motor disposed on the case, a sector plate hinged on the case. The sector plate is hinged with a linkage and a swing link thereon wherein one end of the swing link is hinged with an output crankarm, the other end of the crankarm is connected to the spindle supported on the case. The utility model is characterized in that the spindle is fixed with a worm gear, and the worm engaged on the worm gear is connected to the output end of the motor. The utility model has smooth running, inertialess impact, low noise, less weight, small size, low cost and convenient inspection and repair, further more, the utility model also achieving an electric operation or a manual operation in sit or a remote control.
Description
Technical field
The utility model relates to a kind of electric operating mechanism of operate high pressure isolating switch, is specially adapted to operate big electric current and the big high voltage isolator of operational torque.
Background technology
From present existing electric operating mechanism, its transmission all is by worm and gear speed-reduction apparatus, is directly passed to the isolating switch main shaft after the deceleration.The electric operating mechanism of this structure causes components and parts to be hit easily and damages because impulse inertia is big, even also can cause switch deciliter not in place.It is big also to exist noise simultaneously, and volume is big, shortcomings such as maintenance inconvenience.
The utility model content
The electric operating mechanism that the purpose of this utility model is to provide a kind of and operates steadily, noninertia impacts, noise is little, volume is little, maintenance easily can the operate high pressure isolating switch.
The utility model comprises cabinet, at the motor that is provided with on the cabinet, be hinged and connected to the fanning strip on the cabinet, on fanning strip, be hinged connecting rod, on fanning strip, also be hinged a fork, the other end of described fork and an output toggle arm are hinged, the other end of this output toggle arm is fixedlyed connected with the main shaft on being supported on casing, be characterized in cabinet, affixed worm gear on the described main shaft, be connected with the output of motor with this worm gear engaged worm.
The utility model is by the motor driven worm and gear speed-reduction apparatus, and worm-wheel shaft drives by output toggle arm, fork, connecting rod and the quadric chain formed with the connecting lever that connecting rod is hinged, by connecting lever power output distance.Make the corner of mechanism's output toggle arm be limited in accurate position.By control motor forward and backward, realize branch, the closing operation of mechanism, and the electrical equipment that can realize local operation and remote operation and equipment such as realization and circuit breaker is interlocked and signal indication etc.
Outside cabinet, connect output toggle arm motion buffer unit by contiguous block; Described output toggle arm motion buffer unit comprises two groups of springs, and every group of spring is connected on the contiguous block by bolt, spring block.By this spacing, buffer unit, not only the stroke of output toggle arm to be controlled, and do not caused metal directly to produce hard collision, noise is little, and also prolonged the useful life of product.
The utility model is steady, noninertia impacts, noise is little, in light weight, volume is little, cost is low, maintenance is convenient.In addition, the utility model is electric operating or manual operation on the spot, but also remote operation.
Worm screw, the main shaft that is connected with worm gear are supported on the cabinet by sliding bearing respectively.Purpose is to reduce to rub, increase the service life.
The utility model also is furnished with the manual operation handle, can in outage or electric elements break down and during Installation and Debugging, by manually operating.
Below in conjunction with drawings and Examples content of the present utility model is described in further detail.
