Abstract
The utility model discloses a switching and interlocking mechanism of a high-voltage operating mechanism, which comprises a fixing board, wherein an output shaft and a releasing shaft which are both connected with a power source are arranged on the fixing board, the switching and interlocking mechanism further comprises an interlocking spring which is radially and vertically arranged on the outputshaft and a releasing board which is radially and vertically arranged on the releasing shaft and corresponds to the interlocking spring, the sum of the distance from the axes of the output shaft to the end part of the interlocking spring and the distance from the axes of the releasing shaft to the end part of the releasing board is larger than the axes distance between the output shaft and the releasing shaft, one edge of the end part of the releasing board is provided with a corner angle, and the other edge thereof has smooth transition. The switching and interlocking mechanism of the high-voltage operating mechanism is a switching mechanism with the moderate and individual restoration of the releasing shaft, and further has the interlocking function.
Description
Technical field
The utility model relates to the parts of circuit breaker, especially the combined floodgate interlocking device in the operating mechanism in the circuit breaker.
Background technology
The common mode that is rigidly connected of the general employing of interlock in the current power industry operating mechanism between output shaft and the trip shaft.And in the actual act, trip shaft resets and lags behind output shaft arrival service position.So high pulling torque, high-speed output shaft are to drive interlock by force trip shaft is resetted fast, the impact of its generation causes damage to tripping system element and dropout power source (as solenoid electromagnet) easily.
The utility model content
The purpose of this utility model provides a kind of switching-on mechanism with the trip shaft that can light and slowly reset separately, and has interlock.
For achieving the above object, the utility model adopts following technical scheme: a kind of high pressure operating mechanism combined floodgate interlocking device, comprise fixed head, fixed head is provided with output shaft, the trip shaft that all is connected with power source, comprise that also the interlocking spring that radially is vertically installed on the output shaft and corresponding interlocking spring radially are vertically installed in the dropout plate on the trip shaft, described output shaft axle center to the end of the spring of interlocking distance and trip shaft axle center to the end of the plate of threading off is apart from the distance of shaft centers of sum greater than output shaft and trip shaft, and dropout plate end has corner angle on one side, and another side is a smooth transition.
Described output shaft is positioned at the top of trip shaft, and the dropout plate is a rectangular slab, and dropout plate end is a fillet for the right angle another side on one side.
Under the state that closes a floodgate of threading off, output shaft is crossing to the radius of gyration of the plate end of threading off to the radius of gyration and the trip shaft of the spring end of interlocking.
Described interlocking spring is each circle and tight cylindrically coiled spring.
The beneficial effects of the utility model are: by design interlocking spring and dropout plate, interlock is divided into two independent parts, during the output shaft spinning movement, can drive trip shaft.So trip shaft can normally be returned the snapping position from the dropout position under the effect of light weight reset force after dropout power disappears.Having avoided output shaft is to drive trip shaft by force to reset fast, has stopped the impact that therefore produces, and the tripping system element is accomplished protection.In the rotary course, the round edge of the dropout plate spring of will interlocking is dialled and curved integral body is passed through, after rotation arrives the snapping position, the dropout plate breaks away from the interlocking spring, interlocking spring elastic return original shape under this state, is desired the clockwise direction rotation as trip shaft, the spring end face of then interlocking withstands the dropout plate resistance and ends its rotation, realizes the combined floodgate interlock.In addition, succinct design reduces number of spare parts, and all there is effect preferably the aspect from improving reliability, reduce cost etc.

Embodiment
By illustrated in figures 1 and 2 a kind of high pressure operating mechanism combined floodgate interlocking device, comprise fixed head, fixed head is provided with output shaft 1, the trip shaft 4 that all is connected with power source, output shaft is arranged at the upper right side of trip shaft 4, comprise that also the interlocking spring that radially is vertically installed on the output shaft 12 and corresponding interlocking spring 2 radially are vertically installed in the dropout plate 3 on the trip shaft 4, interlocking spring 2 is each circle and tight cylindrically coiled spring, and dropout plate 3 is a rectangular slab, and dropout plate 3 ends are provided with fillet.As shown in Figure 1, described output shaft 1 axle center to the end of the spring 2 of interlocking distance and trip shaft 4 axle center to the end of the plate 3 of threading off apart from sum greater than the distance of shaft centers of output shaft 1 with trip shaft 4, and under the state that closes a floodgate of threading off, output shaft 1 is crossing to the radius of gyration of dropout plate 3 ends to the radius of gyration and the trip shaft 4 of interlocking spring 2 ends.Fig. 3 shows the user mode schematic diagram of the utility model in the operating mechanism of primary cut-out, the high-power switching-in spring 5 of the power source of output shaft 1 for stretching or compressing, trip shaft 4 is released push rod and is stirred plectrum by push rod by solenoid electromagnet 6 and drives rotation (herein for prior art, Gu do not describe in detail).
Switching-in spring 5 energy storage of operating mechanism at ordinary times also remain on energy accumulating state by fastening device, during the mechanism feed motion, trip shaft 4 dextrorotations go to the position of triping, switching-in spring 5 is released and can be driven output shaft 1 dextrorotation and go to the combined floodgate service position A of mechanism (switching-in spring 5 is a prior art with the driving annexation of output shaft 1, so do not describe in detail), as shown in Figure 2, after mechanism closed a floodgate, trip signal was eliminated, and trip shaft 4 meets position D by the inverse position hour hands spinning reduction returning of triping, in the rotary course, the round edge of dropout plate 3 will be interlocked, and 2 groups of springs are curved to pass through integral body, and after rotation arrived snapping position D, dropout plate 3 broke away from interlocking spring 2, interlocking spring 2 elastic return original shapes, under this state, desire the clockwise direction rotation as trip shaft 4, spring 2 end faces of then interlocking withstand interlock plate 3 and stop its rotation, realize the combined floodgate interlock, as shown in Figure 1.After mechanism's separating brake action, output shaft 1 returns initial position B, and 2 servo-actuateds of interlocking spring are removed, and remove the locking to dropout plate 3 and trip shaft 4, and trip shaft 4 can turn clockwise once more, as shown in Figure 3.
