The protection transformation ratio is configured according to the load current. If the load current changes beyond the allowable value, the transformation ratio must be changed to meet the measurement and protection requirements. However, the transformation ratio must be changed under power outage conditions, which brings economic losses. As an important part of electrical equipment, the distribution network switch plays a role in controlling and protecting electrical equipment and power systems. Its correct configuration and operation are crucial to ensuring the safe and stable operation of the power system.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the integrated equipment for detecting the protection ratio of the distribution network switch has the following advantages: 1. The personnel pull the storage box away from the center of the box body at the same time. The storage box moves outward, causing the two adjacent one-third gears in the horizontal direction to rotate outward, thereby driving the adjacent adjustment shafts in the longitudinal direction to rotate. The outward rotation of the adjustment shaft drives the adjacent connecting rods in the longitudinal direction to rotate outward, and the connecting rods assist the movement of the vertically adjacent storage boxes through the vertically adjacent adjustment seats. When the upper end of the one-third gear contacts the positioning column, the one-third gear stops rotating and the position state is fixed, thereby realizing the expansion and position state of the storage box. The personnel can take the required number of insulating rods from the inside of the storage box according to work needs, or take the required number of current clamps from the inside of the storage slot according to work needs. The battery pack supplies power to the data recorder to realize data recording of the distribution network switch protection ratio detection. When the wire is needed, the personnel rotates the shaft through the driving handle, and the rotation of the shaft drives the winch to rotate, thereby realizing the release of the wire, and waiting for the distribution network switch protection ratio After the detection is completed, the personnel will insert the insulating rods into the longitudinally adjacent elastic clips in turn to realize the assembly of the insulating rods, and the current clips are placed in the storage slots. The personnel rotate the shaft in the opposite direction through the driving handle, and the reverse rotation of the shaft drives the capstan to rotate in the opposite direction, thereby realizing the gathering of the wires, and then pull the two storage boxes toward the center of the box at the same time, so that the two laterally adjacent one-third gears rotate toward the center of the box at the same time, thereby driving the longitudinally adjacent adjusting shafts to rotate inwardly, and the inward rotation of the adjusting shafts drives the vertically adjacent connecting rods to rotate inwardly, and the connecting rods assist the vertically adjacent storage boxes to move toward the center of the box through the vertically adjacent adjusting seats. When the connecting rods are in contact with the vertically adjacent positioning columns, the connecting rods stop rotating, thereby realizing the fixing of the position of the storage boxes, which can realize the rapid assembly of the distribution network switch protection ratio detection device, and effectively improve the assembly efficiency of the distribution network switch protection ratio detection device.

[0014] 2. The personnel press the left and right buttons at the same time, and the buttons in the vertically adjacent slides move toward the center of the box, thereby causing the slide plates to move toward the center of the box. The opposite movement of the slide plates drives the laterally adjacent inclined blocks to move toward the center of the box, and the inclined blocks are disengaged from the vertically adjacent locking plates. At the same time, the inclined blocks cause the laterally adjacent springs to be elastically compressed. Then, with the assistance of the connecting shaft, the personnel flip the box cover upward, and the upward movement of the box cover drives the symmetrically distributed locking plates to move upward, and the locking plates move out of the vertically corresponding sliding openings, thereby realizing the opening of the box cover. After the detection is completed, the personnel flip the box cover in the opposite direction through the connecting shaft, so that the symmetrically distributed locking plates fit into the vertically corresponding sliding openings. When the locking plate is inside the opening, during the downward movement of the locking plate, the vertically adjacent inclined block 1 is first pushed to move in the vertically adjacent slide groove toward the center of the box body, and at the same time, the transversely adjacent springs are elastically compressed. When the locking plates are installed in conjunction with the vertically adjacent inclined block 1, the springs push the transversely adjacent inclined block 1 to move in the vertically adjacent slide groove away from the center of the box body, thereby achieving stable locking of the inclined block 1 and the vertically adjacent locking plate, thereby achieving stable locking of the box cover and the box body, which can realize rapid assembly of the distribution network switch protection ratio detection device and effectively avoid damage to the distribution network switch protection ratio detection device during movement, thereby effectively improving the assembly efficiency of the distribution network switch protection ratio detection device.
