Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: shown in Fig. 1-6:
A kind of circuit breaker, comprises framework 1, main axis transmission system 2, vacuum interrupter 3, oil bumper 4, pressure sensor 5, spring operating mechanism 6 and controller module.Moving contact 31 and fixed contact 32 is provided with in described vacuum interrupter 3; Described spring operating mechanism 6 connects described moving contact 31 through main axis transmission system 2, and described main axis transmission system 2 comprises a separating brake connecting lever 21.Match with separating brake connecting lever 21 in the top of described oil bumper 4, the downward action force of separating brake connecting lever 21 is accepted when breaker open operation action, described pressure sensor 5 is located at the bottom of described oil bumper 4, and the bottom surface of pressure sensor 5 contacts with framework 1, the output signal end of described pressure sensor 5 is connected with controller module.
Specifically, as shown in Figure 1, main axis transmission system 2, vacuum interrupter 3, spring operating mechanism 6 are arranged on the inside of framework 1, and oil bumper 4 is arranged on the bottom in framework 1.Main axis transmission system 2 also comprises first connecting rod 22 and rotor plate 23, described separating brake connecting lever 21 opposing frame 1 is hinged and be connected with described spring operating mechanism 6, specifically separating brake connecting lever 21 is connected with the main shaft 61 of spring operating mechanism 6, is directly driven by the rotation of main shaft 61.One end of separating brake connecting lever 21 is positioned at the top on the top of described oil bumper 4, coordinate with the top of oil bumper 4, and the other end of separating brake connecting lever 21 is connected through first connecting rod 22 one end with rotor plate 23, rotor plate 23 also opposing frame 1 is hinged, and the other end of rotor plate 23 connects with moving contact 31 via an insulated tension pole.
The present embodiment separating brake process is as follows: when the present embodiment circuit breaker is in "on" position, fixed contact 32 and moving contact 31 contact with each other conducting, after circuit breaker receives separating brake instruction, at touch spring power and spring operating mechanism 6 under spring force, main shaft 61 is rotated counterclockwise, separating brake connecting lever 21 is driven to be rotated counterclockwise, on the one hand, the top of oil bumper 4 is clashed in one end of separating brake connecting lever 21, the other end of separating brake connecting lever 21 drives first connecting rod 22 to move upward on the other hand, and then drive rotor plate 23 to be rotated counterclockwise, the moving contact 31 in vacuum interrupter 3 is driven to move downward eventually through the insulated tension pole be connected with rotor plate 23, be separated with the fixed contact 32 in vacuum interrupter 3, complete separating brake action.In the process, pressure sensor 5 can detect the activation signal of separating brake connecting lever 21 and oil bumper 4, the pressure of record oil bumper 4 pairs of frameworks 1, receiving sub-gate signal starts until separating brake completes, the signal of the pressure of oil bumper 4 pairs of frameworks 1 is passed to controller module in real time, and then draw out whole process time m-power curve, and in the display screen display of controller module, the separating brake process of circuit breaker can be supervised.
When circuit breaker is in "on" position, the position of breaker open operation connecting lever 21 is defined as a1, as Fig. 2; When separating brake connecting lever 21 just contacts with oil bumper 4, the position of separating brake connecting lever 21 is defined as a, as Fig. 3; When circuit breaker is in gate-dividing state, the position of breaker open operation connecting lever 21 is defined as b, as Fig. 4; During due to separating brake, the spring force that the tripping spring of spring operating mechanism 6 produces is very large, and separating brake connecting lever 21 first in-position b there will be bounce-back, and separating brake connecting lever 21 extreme higher position arrived of rebound defines b1, as Fig. 5.Separating brake process is described with connecting lever position, following Four processes can be divided into: a1 to a, a to b, b to b1, b1 to b.
Concrete, shown in Figure 6, when circuit breaker prepares separating brake, as manual operation opening button, controller module receives sub-gate signal, and now the controller module record moment is T, work as breaker open operation, main axis transmission system 2 moves, separating brake connecting lever 21 rotates, then separating brake connecting lever 21 touches oil bumper 4, namely separating brake connecting lever 21 is positioned at described a position, and oil bumper 4 receives the downward operating pressure of separating brake connecting lever 21 thus gives framework 1 downward pressure, and pressure sensor 5 detects thus produces jump signal, pass to controller module, recording this moment is A1, when separating brake connecting lever 21 continues to rotate, due to the existence of oil bumper 4, the counter-force that separating brake connecting lever 21 is certain can be given, the pressure giving framework 1 of such oil bumper 4 can reduce gradually and remain unchanged within a period of time, until the cushion stroke of oil bumper 4 reaches maximum, now oil bumper 4 does not recur cushioning effect, namely separating brake connecting lever 21 is in described b position, the spring force of the spring operating mechanism 6 suffered by separating brake connecting lever 21 all passes to framework 1 by oil bumper 4, now pressure sensor 5 detects jump signal, pass to controller module, recording this moment is B1, the power that tripping spring due to spring operating mechanism gives separating brake connecting lever 21 is very large, after separating brake connecting lever 21 reaches b position first, upwards can be rebounded one end distance, the spring force of this spring operating mechanism suffered by time gating connecting lever 21 no longer acts on oil bumper 4, pressure sensor 5 can detect jump signal equally, until separating brake connecting lever 21 bounce-back reaches extreme higher position, i.e. b1 position, separating brake connecting lever 21 again can under the effect of the spring force of spring operating mechanism, continue to move downward, until again reach b point, now oil bumper 4 does not still recur cushioning effect, namely separating brake connecting lever 21 is in described b position again, the spring force of the spring operating mechanism suffered by separating brake connecting lever 21 all passes to framework 1 by oil bumper 4, now pressure sensor 5 detects jump signal, pass to controller module, recording this moment is B11.Like this, the change of pressure sensor 4 pressure in the concrete moment of record A1, B1, B11 and T that controller module is complete, so just obtain resolving the current separating brake process status of road device, namely " T ~ A1 " is referred to as just to divide the time, time " T ~ B1 " is referred to as separating brake, " B1 ~ B11 " is referred to as bounce time, sees Fig. 6.The curve of the now m-power of final output is in the display screen display of controller module.
Like this, the present embodiment just can realize the complete detection to this separating brake process of circuit breaker, and certainly, we must contrast each separating brake data record of circuit breaker, just can better supervise circuit breaker, thus play the function of intelligent management product maintenance, maintenance.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection range of the present utility model.
