Description

technical field [0001] The invention belongs to the technical field of electrical equipment, in particular to a segmented and phase-separated insulator. Background technique [0002] Segmented insulators, also known as partitioned insulators, are overhead contact insulating components that connect two adjacent same-phase power supply sections. The electrical isolation requirements of the catenary; the split-phase insulator is to isolate the power supply sections of different phases on the catenary, so as to avoid short-circuit between phases, and connect with the catenary lines of different phases on both sides to make the catenary a whole. It is necessary to ensure that the locomotive The pantograph passes smoothly under the condition of power failure, and can meet the electrical isolation requirements of the catenary at both ends. At present, there are still some problems in the segmental and phase-separated insulators used in electrified railways, urban light rails, and ...

AI Technical Summary

Problems solved by technology

At present, there are still some problems in the segmental and phase-separated insulators used in electrified railways, urban light rails, and subway contact suspensions: First, the main insulation structure of the segmented insulators and phase-separated insulators adopts the same structure The insulating rod structure of the same size and size, because it has the same structure and size, the overall bending resistance of the insulator is not high. If the overall bending resistance of the insulator is strengthened by adding one or more insulating rods, It will cause the overall weight of the insulator to increase; secondly, neither segmented insulators nor phase-separated insulators can be repaired on site or replaced with vulnerable and consumable parts. When a failure occurs, the whole machine must be replaced, which is costly and inefficient ; The third is that the main slide plate and the arc strike rod in the segmented insulator and the split-phase insulator are connected by welding, and the main slide plate, arc strike rod and auxiliary slide plate together constitute the contact surface of the locomotive pantograph sliding friction When the pantograph slides over the contact surface at high speed, it will impact the components of the contact surface, accompanied by an arc. Under this working condition, the connection and relative position of the main slide plate and the arc striker will be deformed, destroying the contact surface The integrity of the locomotive pantograph cannot be guaranteed to slide smoothly over the contact surface. In severe cases, it will cause the pantograph to be hit and cause an accident
