Abstract
The utility model discloses an urgent separating brake device, including operating means and arc turning arm, operating means comprises mounting panel, hob and reset spring, the mounting panel bears the hob, the reset spring suit is on the hob, the hob is in opposite directions with arc turning arm and holds movable contact. Compared with the emergency opening device of the original permanent magnet circuit breaker, the emergency opening device moves the emergency opening operation hole down to a proper height, and is convenient to operate; the installation position of the arc crank arm can be selected at will, so the device is suitable for most permanent magnet vacuum circuit breakers; and the cooperation of hob and arc connecting lever, perfect solution cam structure promptly the difficult drawback of separating brake device operation for permanent magnet vacuum circuit breaker's manual separating brake is reliable, simple, and the operating force is very little.
Description
Technical field
The utility model is applied to permanent magnet type vacuum circuit-breaker, belongs to control system technical field, is specifically related to a kind of emergency brake-dividing device.
Background technology
Current domestic electrical market, due to permanent magnet type vacuum circuit-breaker, inner body is few, transmission is simple, and failure rate is extremely low, is applicable to frequent operation occasion, but because permanent magnet type vacuum circuit-breaker is Electronic control, just cannot carry out when lacking power supply closing a floodgate, sub-switching operation.For electric power system; the reliability of separating brake is particularly important again; and then in order to satisfied protection demand; add mechanical emergency brake-dividing device; this emergency brake-dividing device is installed on above permanent magnet mechanism; cam-type structure is adopted to be promoted to separating brake direction by permanent magnet mechanism; breaker main shaft is pulled by permanent magnet mechanism axis; and then drive three-phase arc control device separating brake; but because cam-type structure directly promotes baffle plate above permanent magnet mechanism axis, position is fixed, and handle hole is higher; and due to cam eccentricity comparatively large, so require great effort very much.
Utility model content
The utility model solves the deficiencies in the prior art, provides a kind of emergency brake-dividing device, uses simple, novel structure, practical.
The technical scheme that the utility model adopts is: emergency brake-dividing device, comprise operating means and arc connecting lever, described operating means is made up of mounting panel, screw rod and back-moving spring, described mounting panel carries described screw rod, described back-moving spring is sleeved on screw rod, and described screw rod and arc connecting lever hold movable contact in opposite directions.
Further, described mounting panel both sides offer rotating hole, and described screw rod is assemblied on described mounting panel through described rotating hole.
Further, described screw rod one end is helicoidal structure, and the other end is hexagonal prism structure, is also provided with spacing angle below described screw rod.
Further, described arc connecting lever top is arc shape structure, and its lower end offers splined hole.
Further, described arc shape structure be positioned at helicoidal structure top and with described helicoidal structure movable contact.
The beneficial effect that the utility model compared with prior art has: relative to the emergency brake-dividing device of original permanent magnet type breaker, emergency opening handle hole is displaced downwardly to suitable height by the utility model, easy to operate; And can installation site be chosen at random, so this device is applicable to most of permanent magnet type vacuum circuit-breaker due to arc connecting lever; And screw rod coordinates with arc connecting lever, perfectly solve the drawback of cam structure emergency brake-dividing device operation effort, make the manual brake separating of permanent magnet type vacuum circuit-breaker reliable, simply, operating physical force is very little.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind of emergency brake-dividing device, structure as shown in Figure 1, comprise operating means and arc connecting lever 4, described operating means is made up of mounting panel 1, screw rod 2 and back-moving spring 3, described mounting panel 1 carries described screw rod 2, described back-moving spring 3 is sleeved on screw rod 2, and described screw rod 2 holds movable contact in opposite directions with arc connecting lever 4.
In the utility model embodiment, described back-moving spring 3 after the activation screw rod 2 is reset to initial angle.
In the utility model embodiment, as shown in Figure 2, described mounting panel 1 both sides offer rotating hole 11, and described screw rod 2 is assemblied on described mounting panel 1 through described rotating hole 11.Described mounting panel 1 also offers fixing hole 12, and described fixing hole 12 is arranged on framework 5 for stating mounting panel 1.
In the utility model embodiment, as shown in Figure 3, Figure 4, described screw rod 2 is weld assembly, and described screw rod 2 one end is helicoidal structure 21, and the other end is hexagonal prism structure 22, is also provided with spacing angle 23 below described screw rod 2.Described spacing angle, ensures the initial angle after screw rod 2 installation.
In the utility model embodiment, as shown in Figure 1, described arc connecting lever 4 top is arc shape structure 41, and its lower end offers splined hole 42.Arc connecting lever 4 is installed on spline spindle 6 by splined hole 42.
In the utility model embodiment, the arc shape structure 41 of described arc connecting lever 4 be positioned at the top of the helicoidal structure 21 of described screw rod 2 and with described helicoidal structure 21 movable contact.
During use, be fixed on framework 5 by fixing hole 12 by operating means, arc connecting lever 4 is installed on spline spindle 6 by splined hole 42.When described circuit breaker is in "on" position, the arc shape structure 41 of arc connecting lever 4 is in the top of the helicoidal structure 21 of screw rod 2, during manual emergency separating brake, by rotating handles cover in hexagonal prism structure 22, turn clockwise screw rod 2 about 180 °, arc connecting lever 4 is upwards stirred by helicoidal structure 21, spline spindle 6 is driven to rotate, by connecting plate 7 and fish shape connecting lever 8, movable end of vacuum arc extinguishing chamber 9 is pulled to move down, complete separating brake action, screw rod 2 involution to initial angle, is waited for next manual brake separating by back-moving spring 3.
The utility model is coordinated by arc connecting lever and screw rod, achieves a kind of novel magneto
The emergency brake-dividing device of vacuum circuit-breaker.
Above-described embodiment, just preferred embodiment of the present utility model, is not used for limiting practical range of the present utility model, therefore all equivalent variations done with content described in the utility model claim, all should be included within the utility model right.
