Outdoor high-voltage AC isolation switch

Product Introduction

The complete set of isolation switch consists of GW4-252 (D) (W) type isolation switch body, CS14G or CS17G type manual operating mechanism, transmission accessories, etc. It can also be equipped with CJ6 type electric mechanism, etc.

The isolation switch belongs to the double column horizontal opening type, and each single stage is composed of a base, post insulators, output sockets, and contacts. The two post insulators are installed parallel to each other on the bearings at both ends of the base and perpendicular to the base. The main electrical components are installed above two insulators and rotate approximately 90 ° along with the supporting insulators.

The bearing seat of the isolation switch is designed with a fully sealed structure, which can prevent dust, moisture, and harmful gases from entering the bearing seat and causing jamming; The bearing seat is equipped with thrust ball bearings and radial ball bearings inside, which bear the gravity and horizontal force of the isolation switch, so that the operating torque of the isolation switch will not increase after long-term operation. The assembly between each pole and two shafts is connected and driven through connecting plates, adjusting screws, etc. Using stainless steel shaft pins and self-lubricating shaft sleeves, the lubricant is high-efficiency molybdenum disulfide lithium based grease.

The copper braided tape in the outlet socket is fastened to the conductive rod and the terminal block respectively, and the terminal block is used for users to connect the circuit.

The contact fingers of the middle contact part are assembled in pairs, and the contact fingers are clamped between the contact finger seat and the contact by a spring to achieve wear between the contact fingers and improve their service life.

When the isolation switch is equipped with a grounding switch, the interlocking between the main electrical circuit and the grounding switch is ensured by the fan-shaped plate and arc-shaped plate on the base. When the main electrical circuit is closed, the grounding switch cannot be closed, and when the grounding switch is closed, the main electrical circuit cannot be closed.
