SE2000BX Static Exciter

Transcription

1 Rev 3 SE2000BX Static Exciter The SE2000BX Static Exciter is designed to replace most electronic, saturable reactor and rotary exciters used on slip ring or rotor fed electric generators. The SE2000BX offers unique features such as a remote mounted control panel and easy serviceability in the field. The input power and voltage sensing for the SE2000BX are taken directly from the generator AC stator and rectified into a controllable DC input to the main generator rotor. The SE2000BX is a complete static exciter that includes the voltage regulator, power fusing, surge suppression, build up module and connection terminals. Optional devices are offered for the SE2000BX such as an interface card, which allows the SE2000BX to be controlled with power factor controllers and other types of genset and PLC controllers. The SE2000BX has provisions for parallel operation. Specifications: Input Voltage 190 to 250vac, single phase Output Amperage 200adc continuous Type Regulation Flat response/vph Protection Internal fusing Physical Size 24 x 30 x 12 in Weight 50 lbs Voltage Regulator XR500D Build up module AFM500X Build up voltage 6.5vac

2 The SE2000BX is a complete static exciter assembly that is ready for installation. The SE2000BX is designed for simple installation and the voltage regulator assembly is designed so that it can be remotely located for safety and operator convenience. The SE2000BX should be located in a dry and clean area with free airflow over the rectifier section. Installation Instructions: Only professional electrical generator service technicians should install this equipment! Wear safety gear such as eye and face protection and use high voltage blankets and gloves when working on exposed electrical equipment that could cause electrocution or personal injury! Do not operate this generator at speeds lower than synchronous speed with the static exciter energized! 1. Unpack the SE2000BX from its shipping container and inspect the unit for shipping damage or loose parts. 2. Carefully read the installation instructions before attempting installation. 3. Check generator slip rings and brushes for proper contact and ring condition. 4. Mount exciter onto a cabinet or housing. You can mount the regulator control assembly in another location for safety and ease of operation. 5. Install 190 to 240vac single phase to the AC1 and AC2 terminals of the static exciter (Fig A). It is highly recommended that a disconnect switch or breaker is placed between the generator stator and the static exciter for emergency purposes! 6. Install the F+ and F- wiring to the F+ and F- terminals located on the bus bar assemblies of the static exciter (Fig A). 7. Connect up wiring to TB3 as shown in the following wiring diagrams (Fig B and C). 8. Perform a complete final check of the wiring of this static exciter before going to the next step! 9. Turn the regulator off/on switch to off. 10. Start prime mover and bring up to design speed. 11. Turn run/idle switch to run or on. 12. Set up the voltage regulator as per the regulator setup specifications supplied with this static exciter (XR500D Universal Voltage Regulator). This static exciter is shipped set up for 60hz. If the voltage is pulsing, it possibly could mean that the build up relay is plugging. This plugging can be corrected by raising the internal voltage adjustment on the XR500D until the voltage begins to rise and pulls in the build up relay (about 200vac). 13. Set voltage to your specification and observe for at least 10 minutes. 14. Apply load.
