What are the characteristics of outdoor disconnector and indoor disconnector?
(1) The post insulator should be an outdoor insulator with a large skirt.
(2) It is required to be able to break small currents, and some structures have arc extinguishing angles.
(3) In order to ensure that the isolating switch can be reliably opened and closed in the case of icing, an ice-breaking mechanism is also used in some structures.
(4) When the voltage is high, in order to ensure the safety of the inspection and repair of the circuit, a grounding switch is sometimes installed. At this time, after the main switch of the isolating switch is opened, the ground switch is grounded immediately.
Outdoor isolation switches can be divided into single-post scissor type, single-post telescopic type, double-post telescopic type, double-post enclosing type, three-post type according to the different insulation pillar structure, and there are also V-shaped isolation switches.
