[0026] Working principle: the core of the phase insulator is the main insulation part 3, which adopts multi-layer composite insulation material, and the enhanced creepage distance and umbrella skirt structure are designed outside. This design not only effectively isolates the two electrical sections of the catenary, preventing current from flowing from one side to the other, but also significantly enhances the anti-pollution flashover capability. The umbrella skirt structure can block the attachment of rainwater and dust, and can maintain stable insulation performance even in harsh environments, ensuring the safe operation of the railway catenary. When the pantograph passes through the phase insulator, it first contacts the insulation slide 5. The insulation slide 5 includes a main slide and an auxiliary slide, which are connected by a smooth transition section. This design ensures smooth transition of the pantograph, reduces impact force, and avoids the phenomenon of hitting and drilling the pantograph. The end of the insulation slide 5 is fixedly connected with the arc extinguishing angle 4, and the arc extinguishing angle 4 maintains a certain gap with the main insulation part 3, which is used to guide the arc to extinguish in a safe area, thereby protecting the main insulation part 3 from arc damage. The buffer system of the phase insulator is composed of a secondary buffer 11 and a primary buffer 10, which are installed in the clamping groove 9 of the metal support frame 2. When the pantograph passes through, the impact force is first absorbed by the primary buffer 10. The primary buffer 10 is made of polyurethane elastic material, which has high elasticity and impact resistance, and can quickly respond and disperse the impact force. The secondary buffer 11 is made of rubber damping block material, which is integrally arranged with the clamping groove 9, further absorbing and dissipating vibration energy. The metal support frame 2 of the phase insulator and the main insulation part 3 form a clamping structure through the clamping groove 9, and are fixedly connected through the threaded hole 8 and the bolt 7. This design not only ensures the firm connection of each part, but also enhances the mechanical stability of the whole through the triangular structure. The side of the metal support frame 2 is also fixedly connected with the support rod 6, further enhancing the stability of the structure. The connecting piece 1 is integrally arranged with the metal support frame 2, and the metal support frame 2 is triangular. This design further disperses the impact force generated when the pantograph passes through, avoids faults caused by structural deformation, and opens the clamping groove 9 at the end of the metal support frame 2 of the phase insulator for fixing the buffer system. Through the cooperation of the threaded hole 8 and the bolt 7, the installation position and fastening degree of the buffer system can be easily adjusted. This design not only improves the convenience of installation, but also ensures the stability and reliability of the buffer system. At the same time, the overall design of the phase insulator considers the optimization of installation height and inclination angle, ensuring uniform contact pressure when the pantograph passes through, avoiding hard points and hitting the pantograph.
