The GW4 AC high-voltage disconnector (taking the GW4-35kV copper tube type as an example) adopts a double-column horizontal opening structure, usually manufactured as a single-pole type. When three poles are used synchronously, they need to be connected by a connecting rod. Each single pole mainly consists of a base, a post insulator, an outgoing line seat, and a contact head. Its transmission mechanism is as follows: each bearing housing is equipped with a shaft assembly, and the two shaft assemblies are connected and driven by a connecting plate and an adjusting screw. The conductive part uses a flexible connection of tinned copper braided belt, which is respectively fastened to the conductive rod and the terminal board. The contact assembly of the middle contact part adopts external pressure type or self-energizing type contacts, with a rotating-in type structure to reduce wear during switching operations. When the product is equipped with an earthing switch, the main conductive circuit and the earthing switch realize mechanical interlocking through the sector plate and arc plate on the base.
The models of GW4 AC high-voltage disconnectors include GW4-35, GW4-35D, GW4-35ⅡD, etc. Among them, GW4-35 is a non-earthing switch, GW4-35D is an earthing switch, and GW4-35ⅡD is a double earthing switch.
The GW4-126(D)(W) type is suitable for 110kV systems. The GW4-35kV copper tube type disconnector can be matched with the CS11-1 manual operating mechanism, and the GW4-35D type can be matched with the CS8-6D manual operating mechanism. The 35kV complete set of disconnector consists of the GW4-40.5(D)(W) type disconnector body, CSⅡ, CS17 or CS8-6D type manual operating mechanism, transmission accessories, etc., and can also be matched with electric mechanisms such as the CJ6 type. The 110kV complete set of disconnector consists of the GW4-126(D)(W) type disconnector body, CS14G manual operating mechanism, transmission accessories, etc., and can also be matched with electric mechanisms such as the CJ6 type.
