FUNCTIONAL DESCRIPTION:
IS210TRELH2A is a Large Steam Turbine Emergency Trip Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Gas Turbine Control Systems. The Large Steam Turbine Emergency Trip (TREL) terminal board provides emergency overspeed protection to large steam turbines. TREL powers three emergency trip solenoids that can be added to the TREL and TRPL terminal boards, and the VPRO in the protection module controls them. TREL supplies the solenoids with the positive side of the 125 V dc, whereas TRPL supplies the negative side. The I/O controller manages TREL and has nine relays, which are divided into three groups of three and connected to vote inputs that control the three trip solenoids. It also provides emergency stop functions and overspeed protection.
INSTALLATION:
The first I/O terminal block is wired for three trip solenoids. The second terminal block can hold up to seven trip interlocks. The wiring connections are shown in the image below. Connector J2 carries three TRPL power buses, whereas connector JH1 carries the seven-trip interlock excitation voltage.
OPERATION:
The turbine control's only connections are the J2 power line and the trip solenoids. TREL is completely regulated by the VPRO protection module. When a turbine trips in simplex systems, a third cable sends a trip signal from J1 to the TSVO terminal board, which activates a servo valve clamp.
