南通 | LEGRAND 罗格朗单相隔离变压器 044264，160VA

Nantong | LEGRAND Single-phase Isolation Transformer 044264, 160VA

一、项目背景

南通某船舶服务有限公司承接当地船舶企业的配套电气改造与成套项目，船舶机舱电控系统、信号监测设备对供电稳定性、电气安全性要求极高。船舶工况存在潮湿、电压波动、电气干扰强等问题，需要专用进口隔离变压器实现电气隔离，规避漏电、信号紊乱、设备故障等风险，保障船舶设备安全稳定运行。

Project Background

A ship service company in Nantong undertakes supporting electrical renovation and complete set projects for local shipbuilding enterprises. The ship cabin electronic control systems and signal monitoring equipment have extremely high requirements for power supply stability and electrical safety. The marine operating environment features high humidity, voltage fluctuation and strong electrical interference. A special imported isolation transformer is required for electrical isolation to avoid electric leakage, signal disorder and equipment failure, ensuring the safe and stable operation of marine equipment.

二、产品选型

结合终端船舶项目图纸规范与严苛的现场工况，客户指定选用法国原装进口 LEGRAND 罗格朗 044264 单相隔离变压器（160VA）。该产品隶属于罗格朗0442系列控制与信号隔离变压器，遵循IEC、EN官方标准生产，核心参数精准适配工控及船舶配套场景：支持230~400V宽幅输入、115/230V双档位输出，采用B级绝缘材质、绕组间绝缘电压达4510V，具备IP2X防护等级与IK04抗冲击等级。设备标配标准DIN导轨安装结构、螺丝接线端子，体积紧凑，可直接集成于标准电控柜，适配船舶设备50/60Hz工频运行需求，完全满足船舶电气设备长期连续运行的严苛规范。

Product Selection

In accordance with the drawing specifications and strict on-site working conditions of the terminal ship project, the customer adopted the original French imported LEGRAND 044264 single-phase isolation transformer (160VA). Belonging to the LEGRAND 0442 series of control and signal isolation transformers, it is manufactured in compliance with official IEC and EN standards. It supports wide-range input of 230~400V and dual output gears of 115/230V, with Class B insulation and inter-winding insulation voltage of 4510V, as well as IP2X protection grade and IK04 impact resistance grade. Equipped with standard DIN rail mounting structure and screw wiring terminals, the compact device can be directly integrated into standard electric control cabinets, adapting to the 50/60Hz power frequency operation of marine equipment and fully meeting the strict specifications for long-term continuous operation of marine electrical equipment.

三、应用效果

该变压器投入船舶电控系统运行后，整体工况稳定可靠，凭借6.94%标准短路电压参数，实现精准电气隔离，有效滤除船舶机舱潮湿环境下的电网杂波、电气噪声与电压波动干扰，彻底规避弱电控制回路漏电、信号紊乱、设备误动作等问题。产品支持最高50℃环境温度无降额连续运行，运行温升低、静音无噪，无需改造原有船舶标准控制柜结构，安装便捷、适配性强，完全符合EN 61558系列、EN 60204-1、EN 61439-1等行业标准，顺利通过终端船舶企业严格的设备报验与验收。

Application Results

After being put into operation in the marine electronic control system, the transformer runs stably and reliably. With a standard short-circuit voltage of 6.94%, it achieves precise electrical isolation, effectively filtering grid clutter, electrical noise and voltage fluctuation interference in the humid marine cabin environment, and completely avoiding electric leakage, signal disorder and equipment misoperation of weak current control loops. It supports continuous operation without derating at a maximum ambient temperature of 50℃, featuring low temperature rise and quiet operation. It requires no modification to the original standard marine control cabinet with simple installation and strong compatibility. Complying with EN 61558 series, EN 60204-1, EN 61439-1 and other industrial standards, it has successfully passed the strict equipment inspection and acceptance of the terminal ship enterprise.
