AI Technical Summary
The existing 10kV system switchgear fuse fixing device has reduced fixing stability after repeated disassembly and assembly, and is not easy to adapt to fuses of different lengths.
A clamping mechanism is designed, including a first clamping part and a second clamping part. The direction of movement is restricted by the guide groove and the guide block. Combined with the drive component and the pressure booster, the safety is firmly clamped. At the same time, the clamping position can be adjusted to adapt to safetys of different lengths by the connecting component and the anti-disengagement baffle.
It improves the stability and applicability of the safety fixing device, ensuring good clamping performance even after multiple disassembly and assembly, and can adapt to safety devices of different lengths.
