JP cabinets are designed to meet the requirements of standardization, miniaturization and outdoor type of rural low-voltage distribution equipment. They are used in rural power lines and various stations to standardize and miniaturize low-voltage distribution equipment. It integrates power distribution, metering, protection, overload, short circuit, phase loss, undervoltage, overvoltage, residual current overcurrent protection, power side neutral line break and other protection and automatic reclosing, lightning protection, capacitor reactive power compensation, providing safe electricity in rural areas. Provide a guarantee. It can be equipped with multi-circuit outgoing lines for transformers, a special room for accurate measurement of electric energy, anti-theft of electricity, reactive power compensation, voltage and current monitoring, overload and short circuit protection, low-voltage lightning protection, electric leakage and personal electric shock protection and other functions can be integrated into one and assembled with plastic spray treatment or stainless steel inside the box. At the same time, intelligent equipment has also been added to collect on-site operation data, self-diagnose and warn of open circuit operation and bus temperature rise and other conditions, and operate and adjust circuit breaker protection parameters. JP cabinets have the advantages of strong complete sets, small size, beautiful appearance, safe and reliable operation, convenient maintenance, and large selectivity; small footprint, easy movement, deep into the load center, short construction period, and reduced waste.
