At present, when the repulsive force mechanism breaker is used for testing mechanical characteristics, the testing tool consists of a connecting rod, a sensor fixing support and a sensor. Because the repulsive force disc can not be disassembled, the uppermost end of the main shaft is connected with the arc extinguishing chamber, and the lower end of the main shaft is connected with the buffer, the buffer is generally disassembled when the connecting rod is installed; and then a connecting rod with a hole in the middle passes through a main shaft of the repulsive force mechanism, the upper part and the lower part of the connecting rod are respectively fixed by nuts and elastic pads, one end of a displacement sensor is connected with the hole at the end part of the connecting rod by a screw, the displacement sensor is arranged on a fixed support, the fixed support is connected on a side panel of the circuit breaker of the repulsive force mechanism by a bolt, the whole structure is vertical, and the sensor is driven to vertically move by the movement of the main shaft in the vertical direction, so that the measurement of mechanical characteristics is realized.

However, since the connecting rod is generally sleeved on the main shaft of the circuit breaker with the repulsive force mechanism, the buffer needs to be removed firstly in the process of mounting and dismounting the connecting rod, so that the connecting rod can be removed, the test convenience is reduced, and the final test result is also influenced. Meanwhile, when the buffer is in a closing state, the main shaft moves upwards, and the buffer is in a force release state, so that the buffer can be disassembled; however, when the buffer is in a brake separating state, the main shaft moves downwards, the buffer is in a force-exerting state and is pressed tightly, and at the moment, the buffer cannot be detached; therefore, a working condition is generated, namely, when the repulsive force mechanism breaker is in a breaking state and fails to act in the test, the test tool cannot be taken out, and accordingly, corresponding overhaul cannot be performed. In addition, the sensor mounting bracket is generally fixedly mounted on the side mounting plate of the repulsive force mechanism breaker through bolts, so that the position of the sensor mounting bracket is mapped according to the sensor stroke, the outline dimension and the connecting plate mounting position and is punched secondarily, the repulsive force mechanism breaker mounting plate is generally large in thickness (10 mm), the mounting hole is generally small (6 mm), the punching difficulty is increased, and whether the levelness and the verticality of the punching position accurately and directly influence the test result.

Through setting up the one end of the installation connecting rod 110 of connecting rod module 100 to be connected with main shaft 3 can dismantle for need not to dismantle repulsion mechanism circuit breaker and can realize detection device's installation and dismantle, improved the convenience of dismantling. Especially when the repulsion mechanism breaker is in the brake separation and the buffer 2 cannot be disassembled, the disassembly of the detection device relative to the repulsion mechanism breaker can be realized through disassembling the mounting connecting rod 110, so that the overhaul of the repulsion mechanism breaker is facilitated. Through setting up in repulsion mechanism circuit breaker spaced supporting component 310 for installation detection module 200 has reduced the extra processing step that sets up the mounting structure needs on repulsion mechanism circuit breaker, has both simplified detection device's structure, has guaranteed detection module 200 installation's stability again, and then has guaranteed detection result's reliability.

Further, the connection module further includes a connection assembly 130, and the connection assembly 130 is used to connect the first sleeve 111 and the second sleeve 120 so as to connect the mounting link 110 with the spindle 3.
