The invention relates to the technical field of rail transit contact rail systems, and provides a sectional insulator which is provided with a first working surface for a power receiving shoe to slide, a plurality of first grooves are formed in the first working surface, and the first grooves are distributed at intervals in the sliding direction of the power receiving shoe; the first groove comprises a first groove section and a second groove section which are sequentially distributed in the depth direction of the first groove, and a step used for preventing conductive dust from escaping fromthe second groove section to the first groove section is formed between the second groove section and the first groove section. The invention further provides a contact rail system. The contact rail system comprises the section insulator and a contact rail section. According to the section insulator provided by the invention, the phenomenon of power channeling between adjacent power supply sections can be avoided, and thus the safety of personnel in the operation and maintenance process is ensured.

    本申请涉及轨道交通接触轨系统技术领域,提供了一种分段绝缘器,分段绝缘器具有供受电靴滑行的第一工作面,第一工作面上开设有多个第一凹槽,各第一凹槽沿受电靴的滑行方向间隔分布;第一凹槽包括沿其深度方向依次分布的第一槽段和第二槽段,第二槽段与第一槽段之间形成有用于阻挡导电粉尘从第二槽段向第一槽段窜出的台阶。本申请还提供了一种接触轨系统,包括上述分段绝缘器和接触轨分段。本申请提供的分段绝缘器,可以避免出现相邻供电区间出现窜电现象,进而确保运营维护过程中人员的安全。
