Accepted Answer

成都蜀锐（Sunray）供应符合美标(ANSI)和欧标(IEC)的开关柜组件：Arteche saTECH测试插头（TSB 14/18，蜀锐为Arteche授权代理）、States Products FMS测试开关（FMS、FMS R19）、GE MMLB/MMLG测试端子、FT-1测试开关，以及辅助继电器、跳闸闭锁继电器、转换开关、控制开关、互感器与罗氏线圈传感器。Sunray supplies ANSI/IEC switchgear components: Arteche saTECH test blocks, States Products FMS test switches, GE MMLB/MMLG, FT-1, auxiliary relays, selector switches and instrument transformers.

Question 3

成都蜀锐是Arteche授权代理吗？Is Sunray an authorized Arteche distributor?

Accepted Answer

是。成都蜀锐科技（Chengdu Sunray Technology）是Arteche的授权代理，可提供Arteche saTECH二次注入测试插头（TSB 14、TSB 18）及Arteche互感器、传感器等产品。Yes. Chengdu Sunray Technology is an authorized Arteche distributor, supplying Arteche saTECH secondary injection test blocks (TSB 14, TSB 18) and Arteche instrument transformers and sensors.

Question 4

Arteche saTECH TSB 14 和 TSB 18 有什么区别？What is the difference between saTECH TSB 14 and TSB 18?

Accepted Answer

TSB 14 与 TSB 18 都是Arteche saTECH系列二次注入测试插头，区别在于针数与回路数：TSB 14为14针，TSB 18为18针，针数越多可隔离测试的电流/电压回路越多，按保护屏二次回路数量选型。成都蜀锐为Arteche授权代理可供货。TSB 14 (14 poles) and TSB 18 (18 poles) are Arteche saTECH secondary injection test blocks; the higher pole count supports more current/voltage circuits.

Question 5

GE MMLB 和 MMLG 测试端子有什么区别？What is the difference between GE MMLB and MMLG?

Accepted Answer

MMLB与MMLG是GE（通用电气）的测试端子排/测试开关，用于继电保护二次回路的隔离与测试，主要区别在于端子数量与接线配置，按回路数选型。成都蜀锐可供应GE MMLB/MMLG及FT-1测试开关。MMLB and MMLG are GE test terminal blocks for isolating and testing protection circuits, differing in the number of terminals and wiring configuration. Sunray can supply GE MMLB/MMLG and FT-1.

Question 6

罗氏线圈（Rogowski coil）是什么？用在哪里？What is a Rogowski coil and where is it used?

Accepted Answer

罗氏线圈（Rogowski coil）是一种空心环形电流传感器，无铁芯、不饱和、线性度高，用于中压开关柜的电流测量与继电保护，体积小、动态范围大。成都蜀锐供应罗氏线圈、中压室内传感器及PLUGSENS插拔式套管电压传感器。A Rogowski coil is an air-cored current sensor with no saturation and wide dynamic range, used for current measurement and protection in medium voltage switchgear.

Question 7

PLUGSENS套管电压传感器用在什么场景？Where are PLUGSENS bushing voltage sensors used?

Accepted Answer

PLUGSENS是插拔式套管电压传感器，安装于中压开关柜的插拔式套管接口上，用于电压测量与带电显示，节省空间且便于安装。成都蜀锐可供应PLUGSENS套管电压传感器与中压室内传感器。PLUGSENS are plug-in bushing voltage sensors mounted on medium voltage switchgear bushing interfaces for voltage measurement and live-line indication.
