The front damper 36 is hingedly connected to the front hinge seat 38, and the rear damper 37 is hingedly connected to the rear hinge seat 39. When the front damper 36 and the rear damper 37 are both in the reset state, the self-locking seat 35 The front and rear ends are inclined, and when the front side end of the self-locking seat 35 is tilted upward, the terminal seat 4 is in contact with the incoming conductive plate 8. When the front side end of the self-locking seat 35 is tilted downward, the terminal seat 4 is separated from the incoming conductive plate 8. By arranging the self-locking seat 35 on the primary rotating shaft 12, and arranging the front damper 36 and the rear damper 37 at the front and rear ends of the self-locking seat 35, and ensuring that the front damper 36 and the rear damper 37 are in the reset state, the front and rear ends of the self-locking seat 35 are inclined, thereby realizing the locking effect of the primary rotating shaft 12, thereby further improving the safety of the maintenance process.

[0051] A first-level connecting pipe 40 is fixedly installed on the secondary rotating shaft 13, and a first-level hinge seat 41 is integrally formed on the side wall of the first-level connecting pipe 40. A second-level hinge seat 42 is fixedly installed on the isolating switch bracket 1. The first-level hinge seat 41 and the second-level hinge seat 42 are connected by a third-level damper 43, and the third-level damper 43 is hingedly connected to the first-level hinge seat 41 and the second-level hinge seat 42. When the third-level damper 43 is in the reset state, the third-level damper 43 is in the tilted state. When the upper side end of the third-level damper 43 tilts forward, the grounding plate 33 is separated from the grounding conductive plate 10. When the upper side end of the third-level damper 43 tilts backward, the grounding plate 33 contacts the grounding conductive plate 10. Through the arrangement of the first-level connecting pipe 40, the first-level hinge seat 41, the second-level hinge seat 42, and the third-level damper 43, a self-locking effect is formed on the secondary rotating shaft 13 to ensure the connection stability of the grounding component 5, thereby further improving the safety of the device.

[0052] Example 4: On the basis of Example 3, a primary protection structure and a secondary protection structure 49 are fixedly installed on the front crossbeam at the upper end of the isolating switch bracket 1. The primary protection structure includes a mounting tube 50, a force rod 51, a locking rod 52 and a reset spring 53. The inner cavity of the mounting tube 50 includes a force rod mounting cavity and a locking rod mounting cavity.

A primary cam 45 and a secondary limiter 47 are fixedly installed on the primary rotating shaft 12, and a primary limiter 46 and a secondary cam are fixedly installed on the tertiary rotating shaft 14. 48. When the force-bearing rod 51 abuts against the small side of the first-stage cam 45, the reset spring 53 is in the reset state, and at this time, the locking rod 52 does not interfere with the protrusion 54 on the first-stage limiter 46. When the force-bearing rod 51 abuts against the large side of the first-stage cam 45, the reset spring 53 is compressed, and at this time, the locking rod 52 interferes with the protrusion 54 on the first-stage limiter 46, so that the grounding component 5 cannot be flipped upward. Through the setting of the first-stage protective structure, when the terminal block 4 forms a connection with the incoming connection block 2 and the outgoing connection block 3, the grounding component 5 cannot be closed, thereby further improving the safety of the device during actual use.

[0053] The secondary protective structure 49 is the same as the primary protective structure, and the installation directions of the secondary protective structure 49 and the primary protective structure are opposite. The secondary cam 48 is the same model as the primary cam 45, and the secondary limiter 47 is the same model as the primary limiter 46. When the grounding component 5 is flipped to the upper side, the large side of the secondary cam 48 faces the secondary protective structure 49, and at this time, the protrusion structure on the secondary limiter 47 is limited by the secondary protective structure 49, which makes it impossible for the terminal block 4 to be lowered. Through the setting of the secondary protective structure 49, the grounding component 5 cannot be lowered after closing, thereby further improving the safety of the staff during the maintenance process.

[0054] Embodiment 5: On the basis of embodiment 4, a primary mounting hole is provided on the power transmission connection plate 11, and a secondary mounting hole is provided on the ground connection plate 33.

The collar 61 is located between the power transmission connection plates 11 of the same group, and the thickness of the collar 61 is less than the thickness of the incoming conductive plate 8. The first supporting spring 60 and the second supporting spring 62 are both located on the outside of the power transmission connection plate 11. When the first supporting spring 60 and the second supporting spring 62 are actually installed, the first supporting spring 60 and the second supporting spring 62 are The first support spring 60 and the second support spring 62 are both in a compressed state, and the power transmission connection plate 11 is in contact with the collar 61. The structure of the secondary stabilization assembly 56 is the same as that of the primary stabilization assembly 55. By providing the primary stabilization assembly 55 and the secondary stabilization assembly 56 composed of the mounting rod 57, the baffle 58, the nut 59, the first support spring 60, the collar 61, the second support spring 62, the baffle 63 and the limit seat 64, the first support spring 60 and the second support spring 62 exert an inward thrust on the power transmission connection plate 11 and the grounding connection plate 33, thereby ensuring the connection stability between the power transmission connection plate 11, the grounding connection plate 33 and the incoming conductive plate 8, the grounding conductive plate 10. In addition, the provision of the collar 61 can ensure that a certain gap is left between the conductive plates in the same group, thereby facilitating the insertion of the incoming conductive plate 8 and the grounding conductive plate 10 into the matching gap on the power transmission connection plate 11 and the grounding conductive plate 33.
