Abstract

The invention discloses a 10kV pole-mounted vacuum load switch which comprises a box body, a box cover, a three-phase current major loop, an insulating shaft I, an insulating shaft II and an operating mechanism. The three-phase current major loop, the insulating shaft I, the insulating shaft II and the operating mechanism are installed in the box body. Each phase current loop of the three-phase current major loop is mainly composed of a ceramic bushing cable I, a vacuum arc-extinguishing chamber and a ceramic bushing cable II. One end of the vacuum arc-extinguishing chamber is connected with the ceramic bushing cable I, and a spring mechanism is arranged at the other end of the vacuum arc-extinguishing chamber. One end of the spring mechanism is connected with the insulating shaft I, and the other end of the spring mechanism is connected with a moving contact knife fixedly installed on the ceramic bushing cable II through a conductive connecting rod. A static contact knife is arranged on the ceramic bushing cable II and movably connected with the moving contact knife. The insulating shaft I and the insulating shaft II are respectively connected with an operating mechanism. Current instrument transformers are further arranged on the outer surfaces of the ceramic bushing cable I and the ceramic bushing cable II of each phase current. The 10kV pole-mounted vacuum load switch is simple in structure, reasonable in design, stable in running, safe and reliable.

Description

technical field [0001] The invention belongs to switchgear for power transmission lines, and relates to a load switch, in particular to a 10kV pole-mounted vacuum load switch. Background technique [0002] With the rapid development of the power grid, the reliability requirements for safe power supply are getting higher and higher. Aiming at the weak links in the operation of the power grid, the power production department has adopted effective control measures to reduce accidental power outages and reduce the scope of power outages. The safe operation of 10kV feeder overhead lines is directly affected by the surrounding environment and climate conditions due to the open-air erection, and there are problems such as high accident rate, difficulty in finding accidents, and poor safety and reliability. Some users in remote mountainous areas with long overhead lines are often affected by bad weather and cannot use electricity normally. [0003] For power supply companies in far...
