Product Description
Structural Characteristics
·CJM5LE series IoT smart circuit breaker (smart IoT circuit breaker) is a product developed by our company for the ubiquitous power Internet of Things. The current ranges from 40A to 800A. It is an innovative application of artificial intelligence technology in on-site operations in the power industry. It is positioned to provide a first-class product for the intelligent service system with the characteristics of interconnection of everything, human-computer interaction, comprehensive status perception, information processing, convenient and flexible application in all aspects of the power system. Provide solutions for the power distribution side and power consumption side of the power Internet of Things.
·The smart IoT circuit breaker produced by the company can monitor power consumption in real time through the management platform and smart power APP, including current, voltage, leakage current (optional), temperature, power, and power information, and provide early warning and alarm for faults. , Active defense, effectively solve electrical fire prevention and control, and alleviate the pressure of electricity safety management. At the same time, through refined management of energy efficiency, energy saving and consumption reduction can be effectively achieved. Realize the "intelligent" technical characteristics of informatization, digitization, automation, and interaction.
·It has the characteristics of small size, easy installation and use, fixed and adjustable action values, and simple operation. It can be applied to the Internet of Things, which is a network system that realizes the identification, perception, interconnection and control of power grid infrastructure, personnel and the environment. Its essence is to realize the combination of various information sensing equipment and communication information resources (Internet, telecommunications network and even power communication private network), thereby forming a physical entity with self-identification, perception and intelligent processing.
·The communication standard is suitable for meeting various intelligent requirements of smart grid management, and is especially suitable for comprehensive protection at all levels of the power grid. It is the product of choice to cooperate with the operation of the national smart grid. Focusing on each link of the power system, fully apply modern information technology and advanced communication technology such as mobile Internet and artificial intelligence to realize the interconnection of everything and human-computer interaction in all links of the power system, and a smart service system with comprehensive status perception, information processing, convenient and flexible application , including a four-layer structure of perception layer, network layer, platform layer and application layer.
