[0065] When the manual opening and closing shaft 121 is rotated, the opening and closing shaft crank arm 129 assembled on the opening half shaft 127 and the closing latch shaft 128 is driven by the manual opening and closing shaft crank arm 122 to complete the opening and closing operation of the mechanism.

[0068] The isolation separation and combination shaft crank arm 212 is welded and assembled on the isolation separation and combination shaft 211, the isolation idle travel sleeve crank arm 214 is welded on the isolation idle travel sleeve 215, and then assembled on the isolation spring crank arm shaft 216 through the idle travel limit bolt 217, and the isolation separation and combination connecting rod 213 connects the isolation separation and combination shaft 211 and the isolation spring crank arm shaft 216.

[0069] Figure 7 The figure is a schematic diagram of the structure of an isolation spring assembly of an operating mechanism for a pole mounted circuit breaker with an environmentally friendly built-in isolation switch according to the present invention. Figure 7 As shown, the isolation spring assembly 22 includes an isolation spring 221, an isolation spring guide rod 222, an isolation spring bent plate 223, an isolation spring hanging spring shaft 224, an isolation spring pin shaft 225, an isolation spring crank arm 226, an isolation spring crank arm pin 227, a fan-shaped plate 228 and a limit shaft 229.

[0070] The isolation spring crank arm 226 and the fan-shaped plate 228 are welded and assembled on the isolation spring crank arm shaft 216, the isolation spring crank arm pin 227 is welded between the two isolation spring crank arms 226, the isolation spring 221 is assembled on the isolation spring guide rod 222, and stores and releases energy along the isolation spring guide rod 222, the isolation spring bent plate 223 is welded and assembled on one end of the isolation spring guide rod 222, and is installed on the isolation spring hanging spring shaft 224, and the other end is assembled on the isolation spring crank arm 226 through the isolation spring pin shaft 225, and the limit shaft 229 is fixed and is used to limit the fan-shaped plate 228 to the open and close position state.

[0071] Figure 8 The present invention is a schematic diagram of the structure of an isolating spindle assembly of an operating mechanism for a column mounted circuit breaker with an environmentally friendly built-in isolating switch. Figure 8 As shown, the isolation spindle assembly 23 includes an isolation spindle 231 , an isolation spindle arm 232 , and an isolation spindle connecting rod 233 .

[0072] The isolation spindle crank arm 232 is assembled on the isolation spindle 231 , and the isolation spindle connecting rod 233 connects the isolation spindle crank arm 232 and the fan-shaped plate 228 .

[0073] Fig. 9 The figure is a schematic diagram of the anti-rotation component structure of the operating mechanism of the pole-mounted circuit breaker with an environmentally friendly built-in isolating switch of the present invention. Fig. 9 As shown, the anti-heeling assembly 24 includes an anti-heeling rotation shaft 241 , an anti-heeling rotation shaft crank arm 242 , an anti-heeling rotation torsion spring 243 and an anti-heeling rotation isolation main shaft crank arm 244 .

[0074] The anti-heeling rotation shaft crank arm 242 and the anti-heeling rotation torsion spring 243 are assembled on the anti-heeling rotation shaft 241 , and the anti-heeling rotation isolation main shaft crank arm 244 is assembled on the isolation main shaft 231 .

[0075] When the isolation main shaft 231 rotates during closing, the anti-following rotation shaft arm 242 can exert a certain resistance on the isolation main shaft 231 under the action of the anti-following rotation torsion spring 243. The purpose is to prevent the isolation knife from rotating synchronously with the following mechanism during the closing process, resulting in the isolation knife having no inertia force after contacting the static contact and being unable to close reliably.

[0076] When the isolation separation shaft 211 in the isolation separation component 21 is rotated, the isolation spring arm shaft 216 can be driven to move synchronously, so that the isolation spring 221 in the isolation spring component 22 can store energy. When the isolation spring 221 completes energy storage, it starts to release energy, and transmits energy to the isolation main shaft 231 through the isolation main shaft connecting rod 233 and the isolation main shaft arm 232 in the isolation main shaft component 23, completing the isolation closing and opening operation.

[0077] The interlocking mechanism 3 includes a disconnecting interlocking component 31 and a partitioning interlocking component 32 .

[0078] The isolation and separation component 21 is connected to the isolation spring component 22, the isolation spring component 22 is connected to the isolation main shaft component 23, the isolation main shaft component 23 is connected to the anti-following rotation component 24, the isolation interlocking component 31 is connected between the isolation and separation component 21 and the isolation spring component 22, the isolation interlocking component 32 is arranged below the manual separation and separation component 12, and is used to prevent the separation and separation operation of the manual separation and separation component 12, and the isolation interlocking component 32 is connected to the isolation main shaft component 23.

[0079] Fig.10 This is a schematic diagram of the disconnection interlocking assembly structure of an operating mechanism for a pole-mounted circuit breaker with an environmentally friendly built-in disconnect switch of the present invention. Fig.10 As shown, the disconnection interlocking assembly 31 includes a circuit breaker main shaft crank arm 311 , a disconnecting connecting rod 312 and a disconnection interlocking crank arm 313 .

[0080] The circuit breaker main shaft crank arm 311 moves synchronously with the circuit breaker main shaft, the disconnecting interlock crank arm 313 is assembled on the isolating separation shaft 211, and the disconnecting connecting rod 312 connects the circuit breaker main shaft crank arm 311 and the disconnecting interlock crank arm 313 together, which can directly transmit the movement state of the circuit breaker main shaft to the disconnecting interlock crank arm 313.

[0081] When the circuit breaker and the isolator are both in the closed state, when the isolator is operated to open, the isolator cannot be opened due to the obstruction of the isolator interlocking arm 313 to the isolation spring arm pin 227, which can ensure that the circuit breaker is opened first and then the isolator is opened when the power is cut off.

[0082] Fig.11 This is a schematic diagram of the structure of the disconnection interlocking assembly of the operating mechanism for a pole mounted circuit breaker with an environmentally friendly built-in disconnect switch of the present invention. Fig.11 As shown, the partition interlocking assembly 32 includes a short partition interlocking arm 321 , a partition interlocking connecting rod 322 , a long partition interlocking arm 323 and a side panel support column 324 .

[0083] The short partition interlocking arm 321 is assembled on the isolation main shaft 231, and the long partition interlocking arm 323 is hingedly assembled on the side panel support column 324, and rotates with the side panel support column 324 as a fixed point. The partition interlocking connecting rod 322 connects the short partition interlocking arm 321 and the long partition interlocking arm 323, and transmits the motion state of the isolation main shaft 231 to the long partition interlocking arm 323.

[0084] When the isolating knife is in the open state, the isolating interlocking arm length 323 will be between the two pins of the manual opening and closing shaft arm 122, thereby preventing the opening and closing operation of the manual opening and closing shaft 121, and cannot trigger the opening and closing shaft arm 129 to rotate the closing latch shaft 128 to close the circuit breaker, which can ensure that the isolating switch is closed first and then the circuit breaker is closed when power is supplied.

[0085] Compared with the prior art, the present invention has the following beneficial effects:

[0086] The pole switch adapted by the operating mechanism for the pole-mounted circuit breaker with an environmentally friendly built-in isolating switch of the present invention integrates the isolating switch and the circuit breaker in one housing, thereby improving the degree of integration and avoiding the factors affecting the safety of power operation, such as corrosion, oxidation, and rust of the isolating switch. The housing is filled with clean air at normal pressure, making the product more environmentally friendly. An interlocking device is designed between the circuit breaker mechanism and the isolating mechanism to ensure safe operation specifications, making the mechanism compact, easy to operate, safe and stable.

[0087] The applicant of the present invention has made a detailed explanation and description of the implementation examples of the present invention in conjunction with the drawings in the specification. However, those skilled in the art should understand that the above implementation examples are only preferred implementation schemes of the present invention, and the detailed description is only to help readers better understand the spirit of the present invention, but not to limit the scope of protection of the present invention. On the contrary, any improvements or modifications based on the inventive spirit of the present invention should fall within the scope of protection of the present invention.
