Abstract
The utility model is an emergency brake separation device of a circuit breaker. The emergency brake separation device comprises a pedestal installed at a cabinet door; a rotating knob seat installed at the pedestal is arranged outside the cabinet door; and a support that is hinged to the pedestal by a hinging shaft that is arranged vertically is arranged in the cabinet door. A telescopic rod cooperating with a brake separation button of the circuit breaker is installed at the support; and a driving lever perpendicular to the hinging shaft is arranged at the hinging shaft. A rotating button is installed at the rear end of the rotating knob seat; the front end of the rotating knob seat is provided with a push rod cooperating with the rear end of the telescopic rod; and a shifting fork cooperating with the driving rod is arranged at the push rod. The rotating knob is used to control rotating of the shifting fork; the shifting fork drives the driving rod to make rotations, so that the support can drive the telescopic rod to be opened or screwed; and then the rotating knob is pressed, so that the telescopic rod is abutted against the brake separation button of the circuit breaker to open the separation brake; and the circuit breaker is cut off. The provided emergency brake separation device with the reasonable structure can be used conveniently. Under the circumstances that there is no need to open the cabinet door, the separation brake of the circuit breaker can be disconnected, thereby realizing convenient and secure application.
Description
Technical field
The utility model relates to a kind of switching-off device, particularly a kind of for the circuit breaker emergency brake-dividing device on middle-placed switch cabinet cabinet door.
Background technology
On middle-placed switch cabinet commonly used, there is no circuit breaker emergency opening switch now, therefore run into emergency or break down in electric divide-shut brake loop, protective device is when malfunctioning, need to open the cabinet door could operate, and has both extended the time like this, and operating personnel are easily dangerous again.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of simple in structure, easy to use, can not open the just circuit breaker emergency brake-dividing device of energy separating brake of cabinet door.
Technical problem to be solved in the utility model is to realize by following technical scheme, the utility model is a kind of circuit breaker emergency brake-dividing device, be characterized in: comprise the pedestal be contained on the cabinet door, cabinet is provided with the knob base be contained on pedestal outdoors, the jointed shaft be provided with in the cabinet door by vertical setting is hinged on the support on pedestal, the expansion link coordinated with the breaker open operation button is housed on support, described jointed shaft is provided with the driving lever vertical with jointed shaft, the rear end of knob base is equipped with and is revolved button, the front end of knob base is provided with the push rod coordinated with the expansion link rear end, push rod is provided with the shift fork coordinated with above-mentioned driving lever.
Technical problem to be solved in the utility model can also further realize by following technical scheme, and the cross section of described push rod is square, and shift fork is set on push rod.
Technical problem to be solved in the utility model can also further realize by following technical scheme, and described support front portion is provided with pilot hole, and return spring, through pilot hole, also is equipped with in the front portion of expansion link on expansion link.
Technical problem to be solved in the utility model can also further realize by following technical scheme, and pedestal is provided with cover cap, and cover cap is provided with the stopper slot of horizontally set, and shift fork is located in stopper slot, during the shift fork rotation, can only in stopper slot, move around.
The utility model is controlled the shift fork rotation by knob, thereby shift fork drives the driving lever rotation to make support drive expansion link and opens or screw, by knob, can make expansion link be against on the breaker open operation button again opens separating brake, cut off circuit breaker, compared with prior art, it is rational in infrastructure, easy to use, in the situation that do not need to open the cabinet door, can make breaker open operation disconnect, safe and convenient to use.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the utility model further, and do not form the restriction to its right.
With reference to accompanying drawing 1, a kind of circuit breaker emergency brake-dividing device, comprise the pedestal 2 be contained on the cabinet door, cabinet is provided with the knob base be contained on pedestal 2 outdoors, the jointed shaft 7 be provided with in the cabinet door by vertical setting is hinged on the support 8 on pedestal 2, normal support 8 is horizontally disposed, the expansion link 10 coordinated with the breaker open operation button is housed on support 8, described jointed shaft 7 is provided with the driving lever vertical with jointed shaft 73, the rear end of knob base is equipped with and is revolved button 1, the front end of knob base is provided with the push rod 6 coordinated with expansion link 10 rear ends, push rod 6 is provided with the shift fork 4 coordinated with above-mentioned driving lever 3.The cross section of described push rod 6 is square, and shift fork 4 is set on push rod 6, and the endoporus of shift fork 4 is the side of being also, and when push rod 6 rotates like this, shift fork 4 also can and then rotate, thereby makes shift fork 4 stir driving lever 3.
Under normal condition, support 8 and expansion link 10 are horizontal, and be close on the cabinet door, while needing to use, knob rotarily drives shift fork 4 rotations on push rod 6, thereby make shift fork 4 drive driving lever 3 motions, driving lever 3 rotations, make support 8 drive expansion link 10 rotations to the direction vertical with the cabinet door, the front end of expansion link 10 is corresponding with the breaker open operation button, then presses knob, knob drives push rod 6 to travel forward, like this masterpiece is used in to the rear end of expansion link 10, makes forward the breaker open operation button being opened of expansion link 10, can realize operation.
Described support 8 front portions are provided with pilot hole, the front portion of expansion link 10 is through pilot hole, can be not crooked when pilot hole can make expansion link 10 motion, can accurately act on opening button, return spring 9 also is housed on expansion link 10, and return spring 9 is located between the latch on support 8 and expansion link 10, after expansion link 10 travels forward, under the effect of return spring 9, playback backward automatically.Pedestal 2 is provided with cover cap 5, and cover cap 5 is provided with the stopper slot of horizontally set, and shift fork 4 is located in stopper slot, has limited the scope of shift fork 4 rotations.
