High-voltage frequency converter (soft start) bypass switchgear

- Overview

Derun Electric's research and development of high-voltage inverter (soft starter) bypass cabinets are 3.6~12KV, 50(60)Hz bypass power supply devices. They are primarily used for bypassing high-voltage motor inverter (soft starter) control cabinets in power plants, water treatment plants, industrial and mining enterprises, and other facilities. With superior performance and comprehensive five-protection interlocking functions, they offer various solution options based on user requirements. Examples include: three-disconnect switch manual bypass cabinets, three-contact (circuit breaker) configurations, three-contactor (circuit breaker) setups with two-disconnect switches, three-trolley-type contactor (circuit breaker) automatic bypass cabinets, and expandable to one-drag-two or one-drag-three manual (automatic) bypass cabinets.

- Features

1). Concave-convex door structure combined with classic industrial design, featuring smooth lines, strong three-dimensional appearance, and high mechanical strength.

2). The bypass cabinet comes with a channel steel base, matching the form and structure of the inverter (soft starter), offering strong foundation adaptability.

3). Customized external dimensions based on the inverter (soft starter), ensuring an elegant and neat appearance when cabinets are combined.

4). Cabinet frame made of high-quality aluminum-zinc coated steel plates, assembled through multiple folded edges for positioning, providing strong corrosion and oxidation resistance, and excellent mechanical strength.

5). Compatible with various mainstream switches to meet different customer needs.

6). Optional communication PLC module for intelligent automatic switching solutions.
