>>>>>型号:IS200TREGH1BEC 电路板组件 紧急涡轮机保护板
【功能描述】
IS200TREGH1BEC是GE的Mark VI或Mark VIe Speedtronic系统中的电路板组件。这两种系统都用于工业燃气轮机和蒸汽轮机的管理。
该IS200TREGH1BEC与紧急涡轮机保护板（VPRO）相关联，有助于提供独立的紧急超速保护。该系统与主涡轮机控制系统分开，并使用相关的TREG板控制跳闸螺线管。这也适用于TRPG板。IS200TREGH1BEC用于提供125 VDC跳闸功能的正极侧，另一板提供负极。任一板都可以提供脱扣功能。
IS200TREGH1BEC表面共有十二个继电器。其中九个用于形成三组，每组三个继电器，这些继电器对控制跳闸螺线管的输入进行投票。这些继电器具有由VPRO板供电的28 VDC。其他电路板组件包括三个用于电缆连接的（母）d-shell连接器、两个端子排和几个额外的母插头连接。该板还具有十二个金属氧化物压敏电阻、几个跳线以及集成电路和晶体管。电阻器、二极管和电容器等元件安装在电路板的正面和背面。

【英文介绍】
The IS200TREGH1BEC is a circuit board component in GE's Mark VI or Mark VIe Speedtronic systems. Both systems are used in the management of industrial gas and steam turbines.
The IS200TREGH1BEC is associated with the Emergency Turbine Protection Plate (VPRO) to help provide independent emergency overspeed protection. This system is separate from the main turbine control system and uses the associated TREG plate to control the trip solenoid. This also applies to TRPG boards. The IS200TREGH1BEC is used to provide the positive side of the 125 VDC trip function, and the other board provides the negative side. Any board can provide a trip function.
The IS200TREGH1BEC has a total of twelve relays on its surface. Nine of these are used to form three sets of three relays each that vote on the inputs that control the trip solenoid. These relays have 28 VDC powered by a VPRO board. Additional board components include three (female) d-shell connectors for cable connections, two terminal blocks, and several additional female plug connections. The board also has twelve metal oxide varistors, several jumpers, and integrated circuits and transistors. Components such as resistors, diodes and capacitors are mounted on the front and back of the board.
