>>>>>型號:IS200TREGH1BEC 電路板組件 緊急渦輪機保護板
【功能描述】
IS200TREGH1BEC是GE的Mark VI或Mark VIe Speedtronic系統(tǒng)中的電路板組件。這兩種系統(tǒng)都用于工業(yè)燃氣輪機和蒸汽輪機的管理。
該IS200TREGH1BEC與緊急渦輪機保護板（VPRO）相關(guān)聯(lián)，有助于提供獨立的緊急超速保護。該系統(tǒng)與主渦輪機控制系統(tǒng)分開，并使用相關(guān)的TREG板控制跳閘螺線管。這也適用于TRPG板。IS200TREGH1BEC用于提供125 VDC跳閘功能的正極側(cè)，另一板提供負極。任一板都可以提供脫扣功能。
IS200TREGH1BEC表面共有十二個繼電器。其中九個用于形成三組，每組三個繼電器，這些繼電器對控制跳閘螺線管的輸入進行投票。這些繼電器具有由VPRO板供電的28 VDC。其他電路板組件包括三個用于電纜連接的（母）d-shell連接器、兩個端子排和幾個額外的母插頭連接。該板還具有十二個金屬氧化物壓敏電阻、幾個跳線以及集成電路和晶體管。電阻器、二極管和電容器等元件安裝在電路板的正面和背面。

【英文介紹】
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.
