Outdoor - Switch-Disconnector FLa 15/6400, FLa 15/6410 and FLa 15/6410 SA

Product catalog summary

General Information: The document details the specifications and applications of the DRIESCHER outdoor switch-disconnectors, specifically models FLa 15/6400, FLa 15/6410, and FLa 15/6410 SA. These devices are designed for upright assembly and comply with EN 60265-1 standards. They are primarily used as feeder switches for pole-mounted transformer stations. The switches feature arc-extinguishing devices and are filled with Shell Diala D switchgear oil. The construction includes hot-galvanized operating shafts and cycloaliphatic cast resin insulators.

Technical Data: The switch-disconnectors are available in 12 kV, 24 kV, and 36 kV rated voltages with rated currents of 400 A and 630 A. They are designed in both 1-pole and 3-pole configurations. The document provides detailed technical specifications, including rated short-time current, peak withstand current, and various breaking currents.

Design and Function: The switch-disconnectors feature a quick-make, quick-break mechanism with a high-speed operating mechanism that functions independently of manual operation speed. The arcing chamber includes a stainless steel forked piece that aids in the making and breaking operations.

Models and Configurations: The document describes various configurations of the FLa 15/6400 and FLa 15/6410 models, including versions with straight and angled fuse holders. The FLa 15/6410 SA model includes a disconnecting energy storage mechanism for all-pole interruption when a HV-HBC fuse operates.

Operating Mechanisms: The document outlines the arrangement of operating mechanisms for the switch-disconnectors, including single and double operating mechanisms, intermediate bearings, and linkage rods. It also mentions optional features like motor-operated mechanisms and compressed-air operating mechanisms.

Additional Information: The document includes part numbers, dimensions, weights, and drawing numbers for various configurations. It also notes that the switches can be equipped with auxiliary switches and other mechanisms if ordered additionally.
