DETAILED DESCRIPTION

[0024] The application will be further described in conjunction with the embodiments and drawings, but the embodiments of the application are not limited to this.

[0025] As shown in the drawings, an executor applied to an automatic reclosing device comprises a shell 1, contacts installed in the shell 1, a circuit board 2 and an electric tripping mechanism 3. Figures 1-5

[0026] The electric tripping mechanism 3 comprises a motor 31 and a gear set in transmission connection with the motor 31, wherein the motor 31 is connected with the circuit board 2, and when the circuit board 2 is powered, the motor 31 is powered and starts to work, and the output end of the motor 31 is connected with a worm 32; the gear set comprises a primary gear 33, a secondary gear 34, a tertiary gear 35 and a quaternary gear 36, the worm 32 is in meshing connection with the primary gear 33, the primary gear 33, the secondary gear 34, the tertiary gear 35 and the quaternary gear 36 are in meshing connection in sequence, the quaternary gear 36 is provided with a notch 37, and the quaternary gear 36 is connected with a handle 4 at the notch 37.

[0027] The handle 4 comprises an outer handle 41 installed outside the shell 1 and an upper linkage cover 42, a front linkage plate 43 and a rear sensing plate 44 installed inside the shell 1, and the bottom of the upper linkage cover 42 is connected with a protrusion 45; the protrusion 45 is located in the notch 37 and used in cooperation with the notch 37.

[0028] The quaternary gear 36 is connected with a rotating shaft 38 at the center; and the rotating shaft 38 is provided with a reset spring 310.

[0029] When the circuit board 2 is powered, the motor 31 is powered and starts to work, drives the worm 32 to rotate, drives the primary gear 33 to rotate and in turn drives the quaternary gear 36 to rotate, at this time, since the protrusion 45 on the handle 4 is located in the notch 37 on the quaternary gear 36, the quaternary gear 36 rotates, pushes the protrusion 45 to rotate, simultaneously drives the handle 4 to rotate, until the handle 4 is in the position shown in the drawings. Figure 6 ​The shown in the closing state, reset spring 310 at the same time rotating and storing elastic potential energy, at this time due to four gear 36 will block 45 against, handle 4 is difficult to rotate freely, therefore reset spring 310 release elastic potential energy, drive four gear 36 back to as shown in the state Figure 7 The handle 4 is in a free state, not only can be automatically pushed but also can be manually pushed. When the circuit breaker is in the open state, the four gear 36 is reversely rotated to drive the handle 4 to reversely rotate, so that the circuit breaker is in the open state. Similarly, when the circuit breaker is in the closed state, the handle 4 can be automatically pushed and manually pushed. Thus, the manual and automatic switching of the circuit breaker is realized.

[0030] The handle 4 is provided with OFF and ON marks. When the handle 4 is rotated to the OFF position, the circuit breaker is in the open state. When the handle 4 is rotated to the ON position, the circuit breaker is in the closed state.

[0031] The four gear 36 is further provided with a Hall sensor 39. The circuit board 2 behind the rear sensing plate 44 is provided with a closing Hall sensor, an opening Hall sensor and a reset Hall sensor. When the circuit breaker is in the closed state, the Hall sensor 39 on the four gear 36 is rotated to the closing Hall sensor, the closing Hall sensor transmits a signal to the outside, and the circuit breaker is in the closed state. When the circuit breaker is in the open state, the Hall sensor 39 on the four gear 36 is rotated to the opening Hall sensor, and the opening Hall sensor transmits a signal to the outside that the circuit breaker is in the open state. When the Hall sensor 39 on the four gear 36 is rotated to the reset Hall sensor, the circuit breaker is in the reset state. Thus, when the circuit breaker is manually opened or closed, the staff will not be affected, so that the outside world can know and control the state of the circuit breaker at any time, and the debugging and maintenance are facilitated.

[0033] Automatic mode: the handle locking indication mechanism 5 is completely pushed into the shell, and the handle locking indication mechanism 5 does not contact the pressing switch on the circuit board. At this time, the device is in the automatic operation mode.

[0034] Manual mode: the handle locking indication mechanism 5 is pulled out by half, and the pressing switch on the handle locking indication mechanism 5 on the circuit board 2 abuts against, giving a chip on the circuit board an electrical signal. At this time, the device is in the manual mode, and the motor in the executor will not move, and only manual closing and opening can be realized.

[0035] The maintenance mode: all the handle locking indication mechanisms 5 are pulled out, the handle locking indication mechanisms 5 abut against the outer handle 4, at this time, the lock holes 512 arranged on the handle locking indication mechanisms 5 are exposed, after hanging the lock, other people are warned that the equipment is under maintenance, other people are prohibited from closing, and closing is also impossible, so that the personal safety of the maintenance workers is ensured.

In this way, the display of the circuit breaker state under the manual opening and closing state is met.

[0037] The push button 53 is provided with a friction pattern, and the push button 53 can be pushed manually to realize the function of manually pushing the sliding locking block 51 to realize the function of manually pushing the handle 4. The friction pattern is arranged to increase the friction between the hand and the push button 53 when pushing, thereby facilitating the pushing.

[0038] The indication mark 54 is provided with a transparent cover 55 above the indication mark 54 and on the shell 1, and the state of the circuit breaker is displayed by the indication mark 54 displayed in the transparent cover 55, thereby facilitating the observation.

[0039] The connecting piece 52 is connected between the rotating shaft 38 and the sliding locking block 51, the connecting piece 52 is clamped on the front linkage plate 43 of the handle 4, the rotating shaft 38 penetrates through the front linkage plate 43 and the rear sensing plate 44, and the connecting piece 52 is connected to the rotating shaft 38. In this way, when the rotating shaft 38 rotates, the connecting piece 52 rotates, and the handle 4 can also be driven to rotate, so that the rotation of the sliding locking block 51 is realized. In this way, the display of the circuit breaker state under the automatic opening and closing state is met.

[0040] The shell 1 is also provided with an opening and closing measuring mechanism 6, and the opening and closing measuring mechanism 6 comprises an opening and closing time setting knob 61 and an opening and closing frequency setting knob 62.
