Problems solved by technology

This kind of traditional high-voltage load switch is because each vacuum arc extinguishing mechanism is directly arranged on the bottom wall of the housing, and each moving conductive rod and the connecting rod in a corresponding crank arm assembly, as well as each static conductive rod are all made of metal, and are all made of metal. Exposed to the outside, in order to ensure the electrical insulation performance between the circuit equipment of each phase, it is necessary to reserve a large enough distance between the crank arm components, that is, between the vacuum arc extinguishing mechanisms, resulting in a large overall volume of this traditional high-voltage load switch. Not only increases the cost, but also brings various inconveniences to transportation and installation
