145KV 3150A Earthing switch,The neutral point serves various functions, contributing to distinct technical characteristics and operational requirements. The BJ-type transformer neutral point gap grounding protection device plays a crucial role in preserving operational reliability, equipment insulation, and protective measures to ensure consistent performance.

This circuit breaker is a multifunctional low-voltage protection device designed for distribution systems with AC 50Hz, rated voltage below 400V, and rated current below 63A. It is suitable for industrial, commercial, and civilian power networks. Its core functions integrate security protection, equipment protection, and intelligent monitoring, which can significantly improve the reliability and operation efficiency of the distribution system. Core functional highlights: 1. Safety protection 1) Personal safety assurance: Through high-precision residual current detection technology (RCD), indirect contact protection is provided, effectively reducing the risk of electric shock. 2) Equipment and line protection: Integrated overload and short circuit dual protection mechanism, accurately cutting off fault current, avoiding electrical fires and equipment damage. 2. Intelligent monitoring and early warning 1) Leakage pre-alarm function: Real-time monitoring of residual current in the circuit. When abnormal leakage (such as insulation degradation) is detected, an alarm signal is output through a passive normally open contact (dry contact). It can be linked to SCADA, fire protection system or sound and light alarm device without an external power supply to achieve early warning of faults and ensure power supply continuity. 2) Flexible threshold configuration: supports custom setting of leakage alarm values, adapting to sensitivity requirements of different scenarios (such as 30mA/100mA adjustable). 3. Diversified control ability Line and motor control: suitable for occasional switching operations of distribution lines or intermittent start-stop control of small motors, meeting the requirements of nonfrequent operation scenarios. Typical application scenarios: 1) Key power supply areas: places with high requirements for power continuity, such as data centers and hospital IT systems, have alarm nontrip mechanisms to avoid accidental power outages. 2) Equipment protection: Front-end protection for devices such as frequency converters and outdoor electrical cabinets that are susceptible to electrical leakage or environmental impact. 3) Intelligent operation and maintenance: By connecting to the building management system (BMS) through touch signals, remote monitoring and preventive maintenance can be achieved. Product advantages: 1) High reliability: thermal magnetic double trip structure, balancing overload delay protection and short-circuit instantaneous action characteristics. 2) Flexible expansion: an optional communication module, supporting remote status monitoring and fault diagnosis. 3) Easy installation: Standardized modular design, compatible with mainstream rail installation, suitable for compact distribution boxes. Summary: This circuit breaker is designed with the concept of "warning first, safety oriented", which ensures the safety of personnel and equipment while maximizing the stability of system operation. It is the preferred protective device for modern intelligent distribution systems.
