Embodiment 2

[0076] Figure 17 to Figure 19 A second embodiment of the invention is shown.

[0077] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 17 to Figure 19 As shown, the vane switch assembly in this embodiment is no longer provided with the third stationary vane, but the second moving vane and the fourth stationary vane in Embodiment 1 are replaced by the third moving vane 931 and the fifth stationary vane respectively. 932, the third moving blade and the fifth stationary blade are combined to form a double-blade switch; in essence, the second three-blade switch in Embodiment 1 is replaced by the double-blade switch.

[0078] In this embodiment, the first stationary blade 911 , the first moving blade 912 , the second stationary blade 913 , the third moving blade 931 and the fifth stationary blade 932 are sequentially arranged around the circular through hole 90 in a clockwise direction. When the stirring boss rotates with the transmission tur...

Embodiment 3

[0082] Figure 20 A third embodiment of the invention is shown.

[0083] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 20 As shown, the present embodiment no longer sets the first three-leaf switch and the second three-leaf switch, but uses three double-leaf switches instead, and these three double-leaf switches are respectively the first double-leaf switch 94 and the second double-leaf switch 94 switch 95 and the third double-blade switch 96; the first double-blade switch is provided with the sixth moving blade 941 and the sixth stationary blade 942; the second double-blade switch is provided with the seventh moving blade 951 and the seventh stationary blade 952; the third The double-blade switch is provided with an eighth moving blade 961 and an eighth stationary blade 962; see Figure 20 As shown, the sixth stator blade 942, the sixth rotor blade 941, the seventh rotor blade 951, the seventh stator blade 952, the eighth rotor blade ...

Embodiment 4

[0087] Figure 21 A fourth embodiment of the invention is shown.

[0088] This embodiment is basically the same as Embodiment 3, the difference is: see Figure 21 As shown, this embodiment uses three single-handle micro switches to replace the three double-leaf micro switches in Embodiment 3, and each single-handle micro switch is provided with a longer trigger handle with a roller and a slightly protruding contacts on the switch body.

[0089] The three single handle micro switches are respectively a first single handle micro switch 97, a second single handle micro switch 98 and a third single handle micro switch 99; the first single handle micro switch is provided with a first trigger handle 971 and first contact 972, the second single-handle micro switch is provided with a second trigger handle 981 and a second contact 982, and the third single-handle micro switch is provided with a third trigger handle 991 and a third contact 983 . See Figure 20 As shown, the first c...

Abstract

The invention discloses an automatic reclosing drive mechanism including a transmission turbine, an output gear, an output main shaft, a releasing linkage and a circuit board having a central control circuit; the transmission turbine is provided with a cam engaging part, a turbine driven part, a gear driving part, and a starwheel part; the outer peripheral wall of the starwheel part is provided with a toggle boss; the circuit board is provided with a circular through hole and a blade switch assembly; the circular through hole and the transmission turbine are arranged concentrically, the toggle boss is arranged in the circular through hole; the blade switch assembly comprises a first stationary blade, a first moving blade, a second stationary blade, a second moving blade and a fourth stationary blade which are arranged successively around the circular through hole clockwise; the first moving blade can be toggled by the toggle boss to be electrically connected to the first stationary blade or the second stationary blade; the second moving blade may be toggled by the toggle boss so as to be electrically connected to the fourth stationary blade. The automatic reclosing drive mechanism can simplify electric control operation and improves reliability.

Description

technical field [0001] The technical field of the miniature circuit breaker of the present invention, in particular relates to an automatic reclosing circuit breaker. Background technique [0002] According to the needs of my country's power supply network intelligence, the State Grid Corporation of China requires the power supply network intelligence. Therefore, it is necessary for the terminal actuator of the power supply network - the miniature circuit breaker (or miniature circuit breaker) to execute the upper-end signal and have the functions of tripping and closing. Therefore, the current development trend of miniature circuit breakers is that in addition to the traditional manual opening and closing and overcurrent and overload automatic tripping functions, it also needs to have automatic opening and closing and reclosing functions to achieve remote control; especially combined with smart meters, Realize the function of automatic tripping and power failure for arrear...
