Abstract
The utility model discloses a single-arm folding insertion-type ultra-high-voltage direct-current disconnector. The single-arm folding insertion-type ultra-high-voltage direct-current disconnector comprises two single poles which have the same structure and realize synchronous operation through electrical linkage. Each single pole comprises an electric operating mechanism (1), a transmission connecting rod (2), a base support (3), a triangular fixing support (4), operating insulators (5), supporting insulators (6), a transmission bottom base (9), a lower electric conduction tube (10),an upper electric conduction tube (12), a movable contact finger (13) and a static contact (14). According to the disconnector of the utility model, when a main electric conduction tube is switched off, a disconnecting fracture is formed between the main electric conduction tube and the static contact in a horizontal direction. When the disconnector is switched on, the lower electric conduction tube performs arc movement from top to bottom through the pushing of the connecting rod, and at the same time, a gear and a tooth bar are driven to move so as to enable the upper electric conduction tube to perform reverse arc movement, such that the movable contact finger can be engaged with the static contact; when the disconnector is switched off, the movement that is performed when the disconnector is switched on is performed in reverse order. The single-arm folding insertion-type ultra-high-voltage direct-current disconnector is advantageous in stable and reliable movement, small operating force, small switch-on impact, high-stability current, excellent corrosion resistance, long service life and the like.
