The function of intelligent power consumption:
1, short circuit protection
Working principle: When the current value monitored by the intelligent power consumption system is much greater than the alarm threshold current, the protection mechanism of the intelligent power consumption itself makes output protection measures. Avoid the circuit from burning and catching fire due to excessive current.
Advantages: high sensitivity, short protection action time, simplicity and reliability.
2. Leak alarm
Working principle: When the intelligent electricity safety detector monitors the circuit of the distribution box, the leakage current exceeds the warning value when working, and the intelligent electricity system will give a leakage alarm through the intelligent electricity application.
Performance characteristics: the alarm action is sensitive and quick, avoiding personal and property losses.
3, over-current protection
Working principle: When the intelligent power system detects that the current of the electrical equipment exceeds the rated current, it will start the overcurrent protection early warning to protect the equipment.
Performance characteristics:
1, high-speed short-circuit protection, the action time is less than 40ms, and there is no spark eruption at the short circuit. (Effectively control electrical fire)
2, high-speed and accurate lightning protection and overvoltage protection, the action time is less than 40ms, and the digital processing is fast and accurate. ?
3. It has the characteristics of time delay and high-precision over-current protection, and the accuracy reaches 0.1a..
4, ultra-high-speed leakage protection, magical electric shock non-inductive function. ?
5, troubleshooting automatic reset, every time because of a fault trip, built-in mcu accurate judgment, once it is determined that the fault has been eliminated, immediately reset automatically, no need to manually boot, truly maintenance-free. Because of its particularity, different usage scenarios have different and higher technical requirements.
4. Prevent overload
Working principle: Because the current flowing through the conductor exceeds the safe current carrying capacity in the overloaded electrical circuit, when the temperature exceeds this temperature, the insulation will quickly age and even burn out the circuit. Intelligent power consumption can avoid accidents by monitoring line current and temperature in real time.
Advantages: It can prevent electrical safety hazards caused by overload.
5, lighter protection
Working principle: the wire connector is not in good contact, and it will ignite when using electrical appliances. In this case, the traditional leakage protection device usually does not trip. By installing smart electricity, safety failures caused by poor contact and damage of lines can be found in time.
Advantages: high sensitivity, simplicity and reliability.
6, overvoltage protection
Working principle: When the voltage of the protection line monitored by the intelligent power system exceeds a predetermined value, an overvoltage alarm is given, and the power supply is disconnected or the voltage of the controlled equipment is reduced as needed.
7. Undervoltage protection
Working principle: When the line voltage drops to the critical voltage, the intelligent power system will protect the electrical equipment and give an early warning to prevent the electrical equipment from burning due to overload.
Performance characteristics: high sensitivity and high reliability.
8. Self-check
Working principle: communication self-check, quick self-check under field bus communication technology, continuous troubleshooting of all monitoring and testing equipment wiring and data set control equipment. Equipment self-inspection, quick self-inspection and troubleshooting of intelligent electrical equipment to ensure the normal operation of intelligent electrical system.
9. Power limitation
Working principle: With the use of high-power electrical appliances, the current in the circuit will increase, so the requirements for wires and electrical appliances will also increase, and ordinary wires will definitely not meet the requirements. Through the intelligent use of power limit function, when its power increases, that is, exceeds its limited power value, it will give an alarm or even cut off the power supply, thus effectively protecting the safety of circuits or other electrical appliances.
10, electric energy metering
Working principle: Intelligent power consumption system can measure and count electric energy according to different demands and types, and provide basis for electric energy monitoring, energy consumption monitoring and energy consumption analysis.
Features: integrated energy efficiency monitoring and management, flexible configuration, personalized customization, etc.
1 1, online detection
Working principle: Through the smart power system service cloud platform, customers can know the electricity safety situation of enterprises at any time and place for 24 hours through mobile App or Web client, and can remind all security personnel of the safety risks in time through early warning.
12, app remote monitoring
Working principle: Through Smart Power APP, users can log in with authorized account and password, and customers can know the safety situation of enterprise power consumption anytime and anywhere through mobile phones or networked computers, and know the safety situation of power consumption system on the palm.
Performance characteristics: convenient operation, stable operation, easy maintenance and high efficiency.
13, fault alarm
Working principle: It is convenient to set the mobile phone number for receiving SMS alarm through the smart power system. Through setting, alarm information can be sent to the mobile phones of business owners and security leaders.
14, alarm record storage and query function
Working principle: When electric leakage, over-temperature alarm or communication or power failure occurs, the alarm position, fault information, alarm time and other information are stored in the database, and records are also made when the alarm is released and the fault is eliminated. Historical data provides a variety of convenient and fast query methods.
15, three-phase unbalance alarm
Working principle: When the intelligent power system detects that the three-phase current imbalance exceeds the alarm threshold, it starts the alarm delay function.
16, missing phase alarm
Working principle: when the intelligent power consumption monitoring circuit is out of phase, the intelligent power consumption app and intelligent power consumption monitoring equipment give an alarm in the form of sound and light, which is convenient for real-time management, plays the role of timely prevention, shortens the accident handling time and protects the safety of electrical equipment and property. ...
17, fault arc monitoring
Working principle: Many arc faults will not generate residual current in the loop, so the residual current type electric fire detector cannot be used, but it can be detected by the fault arc detector.
18, Big Data Power Analysis Report
The intelligent power consumption cloud platform regularly counts the current electricity consumption data every week and generates a test report. Users can log on to the platform to browse at any time, or view the historical curve of a parameter of a single circuit (such as line temperature, leakage current, etc.) according to your choice. ), compare and analyze the running status of several important loads, check the overall daily, monthly and annual electricity load, and analyze the peak and valley of daily electricity consumption and daily electricity consumption.
19, fault analysis function
Working principle: Through the big data service center of the smart power consumption cloud platform, the alarm reason is analyzed and an abnormal alarm loop is provided.
