SF6ガス漏洩検知監視警報システム

よくある質問 (よくある質問)

Q1: What is SF6 gas and why does it need monitoring?

あ: SF6 (Sulfur Hexafluoride) is an inert gas widely used as an insulating medium in high-voltage electrical equipment such as circuit breakers, 開閉装置, そして変圧器. While non-toxic, SF6 is heavier than air and can displace oxygen in confined spaces, creating asphyxiation hazards. さらに, SF6 は地球温暖化の可能性がある強力な温室効果ガスです 23,500 CO2の倍. Monitoring prevents worker safety incidents and environmental leaks, 規制遵守の確保.

第2四半期: How does the oxygen depletion alarm work?

あ: The system uses an electrochemical oxygen sensor that continuously measures O2 concentration in the monitored space. Normal atmospheric oxygen is approximately 20.9%. When levels drop to 18% (adjustable threshold), the system triggers multi-level alarms including audible sirens, visual strobe lights, and voice warnings. 同時に, the automated ventilation system activates exhaust fans to restore safe oxygen levels. 応答時間は以下です 30 seconds from detection to alarm activation.

Q3: Can the system monitor multiple rooms simultaneously?

あ: はい, the system supports multi-point networking with scalable architecture. A single monitoring host can manage up to 8 independent detection points, with each point monitoring SF6, O2, 温度, 湿度と. For larger facilities, multiple hosts can be networked together via RS485 or Ethernet protocols, creating a centralized monitoring system that can oversee entire substations or facility complexes with dozens of rooms. The GIS mapping feature provides visual representation of all monitoring locations.

Q4: What happens during a power failure?

あ: The system can be equipped with optional UPS (Uninterruptible Power Supply) backup to maintain operation during power outages. In standard configuration, the system will resume normal operation automatically when power is restored, retaining all configuration settings and alarm thresholds in non-volatile memory. Historical data collected before the outage is preserved. クリティカルなアプリケーション向け, we recommend specifying backup power during system configuration.

Q5: How often do sensors need calibration?

あ: SF6 sensors should be calibrated annually using certified calibration gas to maintain accuracy within ±2% FS. Oxygen sensors typically require calibration every 6-12 months depending on usage conditions. Temperature and humidity sensors are factory calibrated and typically require recalibration every 2-3 年. The system includes built-in calibration reminders and can log calibration history for compliance documentation. Our service team can provide on-site or return-to-factory calibration services.

Q6: Is the system compatible with existing SCADA or BMS systems?

あ: はい, the system features standard industrial communication protocols including Modbus RTU/TCP, supporting integration with virtually all SCADA (監視制御とデータ収集) systems and BMS (ビル管理システム). Data points can be mapped to existing monitoring platforms via RS485 serial connection or Ethernet TCP/IP. We provide protocol documentation and technical support for system integration. OPC-UA and other protocols can be supported through custom configuration.

Q7: What is the detection range and accuracy for SF6?

あ: The standard detection range is 0-3000ppm (100万分の1) with accuracy better than ±2% of full scale. This provides resolution of approximately ±60ppm at maximum range, well within requirements for safety monitoring. The national standard alarm threshold is 1000ppm, but this can be adjusted based on local regulations or specific facility requirements. For applications requiring higher sensitivity or different ranges, custom sensor configurations are available.

Q8: Can the system operate in extreme temperatures?

あ: はい, the system is designed for industrial environments with an operating temperature range of -25°C to +70°C (-13°F ～ +158°F). The sensor units and monitoring host are tested for reliability across this entire range. For extreme cold environments below -25°C, heated sensor enclosures are available as an option. The system also operates in humidity up to 95% 相対湿度結露なし. These specifications make it suitable for outdoor installations, unheated equipment rooms, and harsh industrial environments.

Q9: What is the typical installation time?

あ: For a standard single-room installation with one monitoring host and four-in-one sensor unit, typical installation time is 4-6 hours including mounting, 配線, 試運転, ユーザートレーニングと. Larger multi-point installations scale proportionally. Installation can typically be completed without interrupting power supply to the monitored equipment, as sensors are installed in the room environment rather than on energized equipment. Our technical team provides detailed installation manuals and can offer on-site installation supervision or turnkey installation services.

Q10: How is historical data accessed and exported?

あ: The system stores up to 100 days of continuous monitoring data in internal memory. Historical data can be viewed on the 7-inch touchscreen display as numerical tables or graphical trends. Data export is available via USB interface or network connection in CSV, Excel, or PDF formats for reporting and analysis. The system can also be configured for automatic data upload to cloud storage or central servers via Ethernet connection. This supports compliance documentation, 傾向分析, and predictive maintenance programs.

Q11: What certifications does the system hold?

あ: Our SF6 Gas Leak Detection and Monitoring Alarm System holds multiple international certifications including CE (欧州適合性), RoHS (有害物質の制限), and meets GB/T standards for Chinese regulatory compliance. The system is also designed to comply with IEC 61850 standards for power utility communication, OSHA requirements for workplace safety, and EPA guidelines for SF6 emission monitoring. Specific certifications vary by model and configuration. Contact our sales team for certification documentation for your region.

Q12: What warranty and support is provided?

あ: Standard warranty coverage is 24 months from date of installation for all system components. Extended warranty options up to 5 years are available. Our technical support team provides remote assistance via phone, 電子メール, and remote access to system diagnostics. We maintain spare parts inventory for rapid replacement and offer preventive maintenance contracts including annual calibration, 検査, and system optimization. Training programs are available for end-users and maintenance personnel. Global support network ensures service availability regardless of installation location.
