II. Kayayyakin da ake Nema ne da Circuit Breaker Simulator 861
Kamar babban aiki masu sakamakon ta hanyar sakamakon, Circuit Breaker Simulator 861 yana haifar da abubuwan da ke sa a cikin kisa da tattaunawa na biyu da kuma tattaunawa masu mafi girma. Muhimman kayayyakin da ke samu a cikin sakamakon ta hanyar sakamakon ko kuma ayyuka da ke samu sun hada:
1. Kyau na Sakamakon ta Hanyar Sakamakon
- Sakamakon Lokacin Siffofin: Yana iya sakamakon lokacin siffofin da take (20-200ms) da kuma lokacin koyarwa (20-500ms) da karamin adadin ±5ms, wanda yake iya sake gina ayyukan siffofin da kuma koyarwa masu aikinsu daban-daban.
- Amfani da Three-Phase/Phase-Segregated Operation: Yana iya amfani da three-phase simultaneous operation da kuma phase-segregated operation, wanda yake iya haifar da tattaunawan masu aikinsu da kai kadan (6kV zuwa 750kV).
- Tsari Mai Iyali: Impedance na trip/close coil yana iya zama da 100Ω, 200Ω, 400Ω, da sauransu, wanda yake iya haifar da parametarin coil masu aikinsu masu kai gaba.
2. Control da Protection Masu Zan Iya Sakamako
- Masana'antar Control Daban-Daban: Yana iya amfani da remote automatic control da kuma manual operation, wanda yake iya haifar da tattaunawa a cikin aiki.
- Self-Protection Functions: Ana ambaci mekanisin protection mai kiyaye da ke neman aiki masu kasa a cikin abubuwan da ke sa.
- Bayanin Status Mai Iyali: An fito da trip/close signal indicator lights (yan kwafi yana nuna closed, yan ala yana nuna tripped), wanda yake iya sake gina bayanin status na aikinsu a lokacin.
3. Flexible Application Adaptability
- Wide Voltage Compatibility: Operating power supply voltage supports both DC110V and DC220V specifications, with automatic adaptation capability.
- Various Mounting Structures: Can be provided in portable or panel-mounted structures to suit different needs for field testing or fixed installation.
- Isolated Output Contacts: Output contacts are completely isolated from the operating power supply, allowing direct integration with microprocessor-based relay protection test equipment.
III. Typical Application Scenarios
1. Complete Relay Protection System Testing
For new substation commissioning or after protection device replacement, use Simulator 861 for trip/close tests to verify the correctness of the entire loop from the protection device issuing a signal to the circuit breaker executing the action, avoiding direct operation of the actual high-voltage circuit breaker.
2. Personnel Training and Skill Assessment
In training centers, this device can simulate various normal and fault conditions, allowing trainees to master circuit breaker operation procedures and fault handling skills in a risk-free environment, significantly improving training effectiveness and safety.
3. Protection Device R&D Verification
Protection device manufacturers can use Simulator 861 for product testing, simulating different circuit breaker characteristics to verify the compatibility and reliability of protection devices, thereby shortening the R&D cycle.
4. Accident Replay and Analysis
When a system fault occurs, use the simulator to recreate the accident scenario, analyze the protection operation behavior, and provide a reliable basis for accident investigation.
IV. Key Technical Implementation Points
- Parameter Setting: Correctly set trip/close times, impedance, and other parameters based on the actual parameters of the simulated circuit breaker to ensure simulation authenticity.
- Wiring Check: Carefully check the operating power supply voltage selection (DC110V or DC220V) and its compatibility with the control circuit before testing.
- Test Verification: Utilize the built-in auxiliary test circuit and a millisecond meter to accurately measure the time from protection device operation to the simulated circuit breaker action.
- Safety Measures: Even though it is a simulation device, it is still necessary to follow site safety regulations to ensure the testing process is safe and controlled.
V. Application Benefit Analysis
- Economic Benefits: Significantly reduces the number of operations of actual circuit breakers, extends equipment lifespan, and lowers maintenance costs.
- Safety Enhancement: Avoids direct contact with high-voltage equipment by personnel, reducing safety risks.
- Efficiency Optimization: The testing process is not constrained by outage schedules, accelerating project commissioning and protection setting verification progress.
- Training Effectiveness: Provides a platform for repeated practice, enhancing personnel skill levels and reducing the possibility of misoperation.
