FC-CT9825-100T-40A电流互感器产品概述

FC-CT9825-100T-40A是方成(FC)品牌针对中低压电力系统、工业自动化及新能源领域推出的精密电流互感器,核心围绕“大电流精准变换+高安全隔离+易集成安装”设计,适配多场景电流监测与控制需求。

一、产品核心定位与应用场景

该互感器聚焦40A额定电流范围内的精准监测,通过1:100匝数比将大电流转换为易处理的小电流信号,主要应用于:

  • 工业电机保护:实时监测电机运行电流,防止过载、缺相故障;
  • 新能源领域:光伏并网逆变器、电动汽车充电桩的电流检测与计量;
  • 电力配电:低压配电盘的电流监测、电能质量分析;
  • 工业自动化:PLC/DCS系统中执行机构(伺服电机、变频器)的电流状态反馈。

其设计兼顾“性能可靠性”与“安装便利性”,可直接嵌入现有电路,无需复杂改造。

二、关键电气参数解析

1. 电流变换与精度

匝数比1:100,额定输入40A对应次级输出0.4A,输出信号线性度高(无明显饱和失真)。磁芯采用高导磁率材料(如铁氧体或坡莫合金),保证额定电流范围内变换精度达±1%以内,满足工业级监测需求。

2. 隔离安全特性

2.5kVrms隔离电压是核心安全参数,可实现高压侧(220V/380V线路)与低压控制电路(5V/24V单片机)的电气隔离,防止高压串入损坏设备,符合GB/T 13926安规标准。

3. 电感与内阻设计

  • 次级电感10mH:抑制高频噪声(如电磁干扰),保证输出信号纯净度,减少测量误差;
  • 初级内阻≤0.8mΩ:40A电流通过时损耗仅1.28W(P=I²R),几乎不影响原电路功率;
  • 次级内阻≤1.5Ω:内阻稳定,便于与采样电阻、运放等后续电路匹配,无需额外阻抗设计。

三、物理特性与封装设计

采用DIP-4直插式封装,符合标准通孔焊接工艺,适配常规PCB板,安装简单可靠。封装尺寸紧凑(约10mm×8mm×12mm),适合高密度电路布局(如充电桩控制器、PLC模块)。

外壳采用耐高温工程塑料,防护等级IP20,可隔离灰尘与轻微机械碰撞,提升长期可靠性。

四、性能优势与可靠性

  1. 低损耗高转换效率:初级内阻极小,适合对功耗敏感的场景(如充电桩);
  2. 宽温域稳定工作:-40℃~85℃温域,适应工业现场高低温变化(如北方户外充电桩、南方车间设备);
  3. 抗干扰能力强:次级电感抑制噪声,磁芯屏蔽性好,减少电磁干扰影响;
  4. 长寿命设计:DIP封装焊接牢固,优质磁芯与塑料外壳,保证5年以上工业使用周期性能稳定。

五、典型应用案例

1. 电动汽车充电桩电流监测

充电桩输出040A电流,互感器转换为00.4A信号,经采样电阻转电压后输入控制器,实现过流保护、充电计量。

2. 工业电机过载保护

电机额定30A,互感器采集电流,超过35A阈值时控制器切断电源,防止电机烧毁。

3. 光伏并网电流检测

逆变器输出最大35A并网电流,互感器转换为0.35A信号,供监控系统分析电流质量,符合电网要求。

总结

FC-CT9825-100T-40A凭借精准变换、2.5kV高隔离、低损耗与紧凑封装,成为工业电力监测、新能源领域的高性价比选择,满足多场景电流监测与控制需求。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
