72.5KV Outdoor high-voltage SF6 ceramic column single-phase circuit breaker is a three- phase AC 50HZ outdoor high-voltage switchgear, suitable for the control and protection of 72.5KV transmission and transformation system; it can also be used as a contact breaker and opener group. is a three- phase AC 50HZ outdoor high-voltage switchgear, suitable for the control and protection of 126KV transmission and transformation system; it can also be used as a contact breaker and opener group.

The 72.5KV 1600amp Outdoor SF6 high-voltage tank circuit breaker is a unique electrical switch used to disrupt high-voltage electric circuits when faults occur or for regular switching tasks. It relies on sulfur hexafluoride (SF6) gas enclosed in a sealed tank to extinguish arcs and provide insulation. This particular circuit breaker is specially designed for outdoor placement in electrical substations and power distribution systems.

In recent years, engineering construction has become increasingly complex as society, the economy, and technology have advanced. There is a growing demand for compact switch equipment that requires minimal maintenance and is intelligent. Domestic and international switch manufacturing companies are actively developing the 35KV 3150A Medium Voltage Gas Insulated Electrical Switchgear, also known as gas-insulated switchgear (C-GIS), which encases high-voltage components like busbars, circuit breakers, isolating switches, and power cables within a pressure-reduced shell.

The HXGN-12 switchgear Medium voltage AC metal ring main unit switchgear is a comprehensive set of high-voltage AC devices designed for use in three-phase AC ring networks, terminal distribution networks, and industrial electrical systems. Rated for 3.6-12kV and 50Hz, it serves as a reliable and protective solution for receiving, distributing, and regulating electricity. This product adheres to national standards GB3906 and IEC60298, as well as DL/T402 and DL/T404 standards, and meets the "five prevention" locking requirements, ensuring maximum safety and efficiency in its operation.

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.
