GW4 AC high-voltage disconnect switch (taking the GW4-35kV copper tube type as an example) adopts a double-column horizontal opening structure, usually manufactured in single-pole form; when three poles are used synchronously, they need to be connected by connecting rods. Each single pole is mainly composed of a base, post insulators, outgoing line seats, and contacts. 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 flexible connections of tinned copper braided belts, which are respectively fastened to the conductive rods and terminal boards. The contact assembly of the middle contact part adopts external pressure type or self-energizing type contacts, with a rotating-in form to reduce wear during switching operations. When the product is equipped with an earthing switch, the main conductive circuit and the earthing switch achieve mechanical interlocking through the sector plate and arc plate on the base.
The models of GW4 AC high-voltage disconnect switches 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 disconnect switch can be equipped with a CS11-1 manual operating mechanism, and the GW4-35D type can be equipped with a CS8-6D manual operating mechanism. The 35kV complete set of disconnect switches consists of a GW4-40.5(D)(W) type disconnect switch body, a CSⅡ, CS17 or CS8-6D type manual operating mechanism, transmission accessories, etc., and can also be equipped with an electric mechanism such as the CJ6 type. The 110kV complete set of disconnect switches consists of a GW4-126(D)(W) type disconnect switch body, a CS14G manual operating mechanism, transmission accessories, etc., and can also be equipped with an electric mechanism such as the CJ6 type.
