Product Description
% Series Electrical Fire Monitoring System Overview With the rapid development of the economy and the continuous improvement of people's living standards, electricity consumption has increased exponentially, but electrical fires have also increased dramatically,
which has also brought great challenges to the national economy and Huge losses were caused to people's lives and property. According to statistics, most electrical fires are caused directly or indirectly by contact arc
short circuits in electrical circuits. Among them, leakage due to aging of distribution lines, damaged cable insulation, and exposed wires are the main causes of contact arc short circuits. Therefore, timely and effective monitoring of electrical fire hazards caused by leakage in distribution lines is a necessary measure to prevent frequent electrical fires. Currently, newly built high-rise buildings must adopt residual current electrical fire monitoring systems in accordance with fire protection design specifications. This is our starting point for developing a cost-effective residual current electrical fire monitoring system.
The series of residual current electrical fire monitoring systems are suitable for electrical fire monitoring in office buildings, hotels, restaurants, corporate factories and residential power distribution lines
. The residual current type electrical fire monitor in the series is an independent monitoring unit that effectively monitors the leakage of distribution lines to the ground and prevents electrical fires caused by leakage of electrical lines to the ground. It is used in conjunction with circuit breakers in distribution lines to effectively monitor and protect ground leakage short circuits.
The model can independently monitor and protect the line leakage of regional power distribution circuits, or it can form a multi-layer monitoring network with repeaters, hubs, serial servers and computers through communication functions to monitor multiple areas and multiple areas. Realize remote real-time monitoring, recording and central monitoring at different levels. The rating of this monitor is adjustable in multiple settings, with high flexibility, simple use and perfect design. Therefore, it is not only suitable for the selection of high-end intelligent buildings, but also especially suitable for the configuration of factories and mines, ordinary commercial buildings and residential buildings.
Function introduction◆.Real-time monitoring
Monitor the leakage current in the monitoring area in real time, and display each monitoring area in real time on the monitor and central monitoring computer
Leakage current value and forecast of distribution lines The alarm threshold value, alarm action value, alarm action time, fault area address and alarm status are displayed on the central monitoring computer
The leakage current change curve and various parameters and status are recorded
◆. Regional monitoring and grouping Network monitoring
The ground leakage current in the protection area can be monitored by an independent monitor, or the monitoring of each area can be hierarchically organized into a network to centrally monitor the residual current pre-alarm threshold, alarm action value, and alarm The action time is adjustable in multiple settings, and can be set on site or remotely
◆. Pre-alarm function
When the real-time leakage current exceeds the rated residual current pre-alarm threshold, the buzzer will alarm , the alarm indicator light flashes
The operator can promptly check the leakage fault point in the alarm area and eliminate the leakage fault, thereby nipping the fire hazard in the bud
◆. Leakage protection function
According to different The regional site and actual conditions require setting the residual current alarm action value and action time to meet
regional leakage protection requirements and avoid overstep tripping or large-area tripping. When the real-time leakage current exceeds the rated residual current alarm action value, an alarm
/>The alarm output can cause the circuit breaker to trip and cut off the power supply
◆. Query function
The cumulative number of alarms can be viewed through the query function
◆. Communication function
Connected through the bus, The protocol can be used to realize data transmission between the monitor and the computer

◆. When the monitor provides a /(resistive load )'s active output (~ terminal), so the user can connect an external alarm or other alarm equipment
It can also be used in combination with a shunt tripper and a circuit breaker to achieve the function of cutting off the main circuit. The recommended wiring method See pictures, pictures

Networking scheme
◆ Independent monitoring
For a single or a small number of monitors and a short communication distance (), direct connection can be used, as shown below
//~~//
◆Through a repeater Connection
For a single or a small number of monitors but a long communication distance (), they can be connected through a repeater to ensure communication quality, as shown below
//~~//
◆Connect the network through a hub
When there are a large number of monitors and the communication distance is long, they can be connected through a hub, and the hub changes the commonly used serial connection to a star connection to facilitate wiring

◆Connect via Ethernet
If you need to convert the serial port form to network form, you can connect the monitor to the computer through the serial port server. The connection method is as shown below
// approximately The picture shows the cooperation of the hub
The serial port server and router can be shared by multiple computers. When the number of monitors exceeds the number of hub or repeater interfaces, the monitors can be connected in series (this method is also applicable to other solutions)
