ROBICON **无谐波

Robicon **无谐波中压变频器

“Robicon **无谐波”变频器是无可争议的**市场头号中压变频器品牌，它具有非常好的可调节性，低压单元采用串联方式――并在此基础上形成中压变频器，从而适应大范围的电压和功率定额需求。其功率范围在 150 kW至120 MW 之间，“Robicon **无谐波”变频器的主要特点包括：安装和调试较为简单（变压器、功率单元和闭环控制全部集中在一个单元内），电压质量较高，即使再严格的谐波含量要求也能满足。不仅如此，由于采用了先进的单元旁路功能，使得驱动器的可靠性较高――即在不足四分之一秒的时间内将故障单元通过旁路功能短路――同时采用了具有处理容错功能的 ProToPS? 保护系统。

• Very small footprint
• No output transformer required – motor voltage 2.3 to 13.8 kV can be provided directly
• No harmonic line filters or power factor compensation required
• Engineered to continue operating through component failures that would completely disable conventional drives. The patented cell-based configuration maximizes availability, letting the customer determine the right time to perform maintenance, while the modular design reduces system repair time to minutes.
• The cell bypass option ensures automatic bypass of a failed power cell in typically 250 ms or less (less than 1/2 of a second) through a redundant bypass control that is completely separated from each power cell.
• The optional process-tolerant protection system (ProToPS) in combination with cell bypass supports the high reliability and availability of the SINAMICS PERFECT HARMONY GH180. Instead of tripping the drive and automatically shutting down the system due to a malfunction, ProToPS provides a hierarchical system of warnings. This control strategy allows time to evaluate the situation and respond appropriately to avoid a system shutdown.
• No common mode motor insulation stress – the SINAMICS PERFECT HARMONY GH180 includes an integral isolation transformer
• Compatible with both new and existing 1.0 service factor induction or synchronous motors from any manufacturer without any special design considerations
• No significant drive-induced torque pulsations – even at low speeds
• No need for expensive flexible couplings
• No cable length restrictions

• Retrofit
• Power generation – SINAMICS PERFECT HARMONY GH180 can ride through voltage dips or power outages
• Pulp/Paper – SINAMICS PERFECT HARMONY GH180 provides high output voltage at low power
