Nanjing General Hospital Tangshan BranchThis project is designed toOne 10kV user station, two 400V distribution rooms, and 156 floor distribution boxes. The high and low voltage distribution room is equipped with Sfere PMS power monitoring system provided by Jiangsu Sfere Electric. The system records and analyzes real-time data collected by microcomputer protection devices, multifunctional power instruments, intelligent measurement and control devices, transformer temperature controllers and other equipment to ensure the reliability of hospital electricity supply.

In addition, the floor distribution box is provided by Jiangsu Sifei ElectricThe SCK600 electrical fire monitoring system consists of SCK680-B series electrical fire monitoring equipment, SCK600A series electrical fire monitoring detectors, LD series residual current transformers, and NTC temperature sensors. Through real-time monitoring of residual current and temperature in the circuit, the system effectively improves the safety of the hospital's power distribution system.

The SCK600 electrical fire monitoring system can be installed in TN-S, TN-C-S, and local TT low-voltage distribution systems. The system includes SCK680 electrical fire monitoring equipment, SCK600 electrical fire monitoring detectors, residual current transformers, temperature sensors, and other accessories. Electrical fire monitoring detectors are used to monitor parameters such as residual current, load current, and cable temperature in the circuit, and upload them to the monitoring equipment for centralized control and management; When the relevant parameters in the circuit are abnormal, the monitoring equipment emits an audible and visual alarm to indicate the alarm location. At the same time, the on-site detector emits an audible and visual alarm and control signal to remind users to investigate or replace the hidden danger circuit, reducing the risk of fire caused by electrical reasons.

system architecture

The SCK600 electrical fire monitoring system adopts a three-layer distributed design of equipment layer, communication layer, and management layer to achieve decentralized control and centralized management. For medium to large area monitoring, regional multi-level monitoring devices can be cascaded to achieve unified operation and settings, and display and alarm by region. For monitoring small and medium-sized areas, a single monitoring device is used to implement an integrated monitoring system. The detector signals in each installation area are all sent to the monitoring device for centralized processing, display, alarm and management. The system has a high cost-effectiveness.

System functions

real-time monitoring

The system monitors the residual current and temperature values of each circuit in real-time, and displays detailed circuit names, numbers, and various functional buttons on the main interface.

Alarm settings and prompts

The system supports remote setting of residual current and temperature alarm values, as well as various circuit information and status. When an alarm occurs in the circuit, the system emits an audible and visual alarm signal, while the interface shows a noticeable color change and automatically records detailed sequence of events. The number of event records is≥ 60000 items for easy traceability.

Alarm and fault records

The system is equipped with a dedicated historical database that provides historical alarm records and historical fault records. Users can access, query, and print them at any time through the report interface. Users with advanced privileges or above can delete records one by one or all by themselves.

Alarm printing

The monitoring equipment is equipped with a micro printer that can automatically/Manually print alarm and fault information. Support setting the interface to automatically print information when an alarm/fault occurs.

Historical data trend curve

The system supports querying the remaining current and temperature data stored in history in a curve format, and the query time interval and circuit can be dynamically set. The interface can reflect in real-time the changes in residual current or temperature during any given period of time.

Status information display

The system can display various real-time status information (power supply status, equipment fault status, alarm status, and the current working status of all communication devices, etc.) in sync with the monitoring device indicator lights.

System fault self-test

The monitoring equipment displays the real-time operation status of various internal functional modules and has a fault self diagnosis function. At the same time, it displays the cause of the fault in real time on the system interface and judges the communication status of detectors in each area in real time. It intelligently self checks the faults of the entire system.

User Rating Management

The system is divided into three levels of permission management, and different operations require corresponding permission levels to prevent misoperation and illegal entry.

System operation informationThe system has an independent information window that records all operational information of the device after it has started running, facilitating comprehensive judgment of the current status of the operating system.

In conclusion

The SCK600 electrical fire monitoring system is a new generation of electrical fire monitoring system developed with the main purpose of early warning and monitoring of electrical fires, utilizing digital technology and adopting a distributed design scheme. This system has passed the mandatory 3C certification of the National Fire Electronic Product Quality Supervision and Inspection Center, and can be applied to large shopping malls, hotels, public buildings, intelligent buildings, petrochemicals, industrial and mining enterprises and other places with high fire hazards.
