As shown in fig. 1, the interlocking mechanism of the disconnecting switch and the circuit breaker according to the embodiment of the present invention includes: an isolator module 100 provided with an operation unit 110; a circuit breaker module 200 provided with a switching-on/off mechanism 210; a first shielding member 300 movably connected to the disconnecting switch module 100, the first shielding member 300 being capable of shielding the operating portion 110; the first linkage mechanism 400 is connected with or abutted against the switching-on/off mechanism 210, the first linkage mechanism 400 is connected with the first shielding piece 300, and the switching-on/off mechanism 210 can drive the first shielding piece 300 through the first linkage mechanism 400.
The first linkage mechanism 400 is connected or abutted with the switching-on/off mechanism 210 so as to drive the first shielding piece 300 when the switching-on/off mechanism 210 acts, when the circuit breaker module 200 is switched on, the switching-on/off mechanism 210 acts, so that the first shielding piece 300 shields the operating part 110 of the isolating switch module 100, an operator cannot operate the isolating switch module 100, and further when the circuit breaker module 200 is switched on and the circuit breaker module 100 is not switched off, namely, the circuit breaker module 200 is in a switching-off state when the isolating switch module 100 is switched off. With the structure, whether the first shielding piece 300 shields the operating part 110 or not is related to the state of the switching-on/off mechanism 210, so that the effect that the disconnecting switch module 100 can be switched off after the circuit breaker module 200 is switched off is realized, the structure is simplified, and the adjustment is convenient.
The operation unit 110 of the disconnector module 100 may be an operation handle hole into which an operator can insert an external handle member to switch the on/off state of the disconnector module 100. The switching-on/off mechanism 210 of the circuit breaker module 200 may be an embodiment including transmission members such as a crank arm, and when the circuit breaker module 200 is switched on or switched off, the transmission members move to drive the first linkage mechanism 400 to move, so that the first shielding member 300 shields the operating portion 110.

When the second shielding member 500 shields the operating portion 110 of the disconnecting switch module 100, the locking mechanism 700 is unlocked, and the opening and closing mechanism 210 can act to switch the closing and opening states of the breaker module 200; when the second shutter 500 moves and does not shield the operating portion 110 any more, the locking mechanism 700 is locked, and the switching mechanism 210 cannot switch the switching state between the switching on and the switching off.
With this structure, when an operator performs a switching-off operation, the circuit breaker module 200 is switched off, and then after the disconnecting switch module 100 is switched off, the operation portion 110 is not shielded by the first shielding member 300 and the second shielding member 500, that is, the circuit breaker module 200 is in a switching-off and locking state, and at this time, the operator cannot switch the circuit breaker module 200 to a switching-on state. When an operator performs a closing operation, the disconnecting switch is closed through the operating portion 110, then the second shielding member 500 is operated to shield the operating portion 110, the locking mechanism 700 is unlocked, then the opening and closing mechanism 210 is operated to switch the circuit breaker module 200 to a closing state, and at this time, the first shielding member 300 also shields the operating portion 110 along with the closing action of the opening and closing mechanism 210.
Through the above process, when the disconnector module 100 and the circuit breaker module 200 are both in the open-circuit state, the locking mechanism 700 of the circuit breaker module 200 is locked, so that the circuit breaker module 200 cannot be switched on first, and an operator needs to control the second shielding piece 500 to unlock, because the second shielding piece 500 is located on the disconnector module 100, the open-circuit state of the disconnector module 100 is necessarily noticed at this time, the second shielding piece 500 is controlled after the disconnector module 100 is switched on, the locking mechanism 700 of the circuit breaker module 200 is unlocked, and the open-circuit mechanism 210 is controlled to switch on the circuit breaker module 200. Therefore, the circuit breaker module 200 is prevented from being switched on first, and the circuit breaker module 200 is switched on again after the isolating switch module 100 is switched on.

The structures of the first adjusting arm 420 and the first transmission rod 410 control the rotation center of the first adjusting arm 420, so that the length of the force arm connected with the abutting piece 430 is smaller than that of the force arm connected with the first transmission rod 410, and further the stroke of the abutting piece 430 can be enlarged, that is, the stroke of the first shielding piece 300 moving along with the abutting piece 430 is increased, so that the first shielding piece 300 can shield the operation part 110 more easily.
By controlling the position of the rotation center of the first adjusting arm 420, that is, the position where the first adjusting arm 420 is rotatably connected to the circuit breaker, the ratio of the moving stroke of the abutting piece 430 to the moving stroke of the first shutter 300 can be controlled.

The second driving rod 610 and the second adjusting arm 620 are configured to control the rotation center of the second adjusting arm 620, so that the length of the force arm connected to the connecting member 630 is smaller than the length of the force arm connected to the second driving rod 610, and the force required by the second shielding member 500 to drive the connecting member 630 to move can be reduced, that is, the operator can drive the locking mechanism 700 to move easily through the second shielding member 500, which is beneficial to more convenient operation.
By controlling the position of the rotation center of the second adjusting arm 620, that is, the position of the second adjusting arm 620 rotatably connected to the circuit breaker, the ratio of the length of the moment arm of the connecting member 630 to the length of the moment arm of the second transmission rod 610 can be controlled.
