结构特点 Structural Features
断路器采用三相瓷柱式单断口结构，每相配用一个弹簧操动机构，三相电气连动，故外观新颖精致。断路器以SF6气体作为绝缘和灭弧介质，采用指针式密度继电器对其压力和密度进度监控。由于采用自能式灭弧原理，且在断路器运动系统中进行了优化设计，故有效地提高了机械效率，最大限度地降低了操作功；
开断性能优良，电寿命长；
该产品每个极柱安装在一个机构箱上，机构箱居中安装在地脚上，箱内有弹簧操动机构和电气控制单元，机构的输出杆与拐臂相连，机构箱支架表面采用热镀锌工艺，紧固件采用热镀锌处理，机构箱外壳采用不锈钢材料，故产品的抗腐蚀性能优良。机械可靠性高，能频繁操作；
由于六氟化硫气体固有的高绝缘强度，且断路器采用最优的触头运动，所以断路器开断容性电流无重燃;外绝缘水平高，外绝缘为大爬距设计，耐污秽性能优良。
载流能力强：按额定电流4000A的1.2倍进行温升试验，各点温升仍有较大的裕度；产品整体外观结构紧凑，现场安装调试方便，维护工作量小。
The circuit breaker adopts a three-phase porcelain column single-break structure, with a spring operating mechanism for each phase. The three-phase electrical interlock gives it a sleek and sophisticated appearance. The breaker uses SF6 gas as an insulating and arc-quenching medium and is monitored for pressure and density by a pointer-type density relay. Due to the self-energy arc extinguishing principle and optimized design of the breaker's mechanical system, the mechanical efficiency is significantly improved, and the operating poweris minimized. The breaker offers excellent breaking performance and a long electrical lifespan.
Each poleis mounted on an individual mechanism box, which is centrally installed on the base. Inside the box, there is a spring operating mechanism and an electricalcontrol unit. The output rod ofthe mechanism is connected to the operating lever. The mechanism box bracket is treated with hot-dip galvanizing, and the fasteners are also hot-dip galvanized. The box housing is made of stainless steel, providing excellent corrosion resistance. The breaker boasts high mechanical reliability and is capable of frequent operations.
Thanks to the inherent high insulation strength of SF6 gas and the optimized contact movement of the circuit breaker, it can interrupt capacitive currents without re-ignition. The external insulation has a high creepage distance and excellent resistance to pollution. It also has strong current-carrying capacity. During a temperature rise test conducted at 1.2 times the rated current of 4000A, there is still a significant margin for temperature rise at each point. The overall appearance of the product is compact, easy to install and debug on-site, and requires minimal maintenance.

结构特点 Structural Features
断路器采用三相瓷柱式单断口结构，三相配用一个弹簧操动机构，居中布置，三相连动，故外观新颖精致。断路器以SF6气体作为绝缘和灭弧介质，运行时断路器三极SF6气体连通，并采用指针式密度继电器对其压力和密度进度监控。由于采用自能式灭弧原理，且在断路器运动系统中进行了优化设计，故有效地提高了机械效率，最大限度地降低了操作功；
开断性能优良，电寿命长；
安装底架及支撑采用优质钢板整体折弯而成，表面处理全部采用热镀锌工艺，所有外露紧固件采用高强度材料并热镀锌处理，或采用不锈钢标准件，机构箱外壳采用不锈钢材料，故产品的抗腐蚀性能优良；
机械可靠性高，能频繁操作;
由于六氟化硫气体固有的高绝缘强度，且断路器采用最优的触头运动，所以断路器开断容性电流无重燃；
外绝缘水平高，外绝缘为大爬距设计，爬电比距≥31mm/kV,耐污秽性能优良。在恶劣的环境下也可安全运行；载流能力强:按额定电流3150A的1.2倍即3780A进行温升试验，各点温升仍有较大的裕度；
产品整体外观结构紧凑，现场安装调试方便，维护工作量小。
The circuit breaker uses a three-phase porcelain pillar single-break structure, with a spring-operated mechanism centrally arranged and linked across the three phases, giving it an elegant and compact appearance. SF6 gas serves as both the insulating and arc-quenching medium. During operation, the three poles of the circuit breaker are interconnected with SF6 gas, and a pointer-type density relay monitors the pressure and density of the gas.
Thanks to the use of the self-energy arc-extinguishing principle and optimization of the breaker's mechanical system design, mechanical efficiency is greatly improved, reducing operating power to a minimum. The breaker has excellent interrupting performance and a long electrical life.
The installation base and support frame are made from high-quality steel plates that are integrally bent. The surface is treated using hot-dip galvanizing, and all exposed fasteners are made from high-strength materials with either hot-dip galvanized or stainless steel components. The mechanism 's box is made from stainless steel, providing excellent corrosion resistance and high mechanical reliability for frequent operation.
With the inherent high insulating strength of SF6 gas and optimal contact movement, the breaker is capable of interrupting capacitive currents without re-ignition. The external insulation is designed with a large creepage distance, ≥ 31mm/kV, ensuring excellent resistance to contamination. It operates safely in harsh environments. The breaker also has a strong current-carrying capacity: under a current of 1.2 times the rated value (3150A × 1.2 = 3780A), the temperature rise tests show a considerable safety margin. The product's overall appearance is compact, making on-site installation and commissioning easy with minimal maintenance required.

结构特点 Structural Features
产品采用倒置式结构，由壳体、防爆片、器身、套管、底座、密度继电器等部件组成。产品内部带有改善电场的屏蔽件，二次引线接在密闭的接线盒内，壳体有三通式壳体和钟罩式壳体两种。
主绝缘采用同轴圆柱形均匀电场结构。一次导杆、二次屏蔽相互构成同轴圆柱形均匀电场。改变电流比，可采用一次串并联方式:也可采用一次并联，所有变比从二次抽头获得。
壳体上部加装了防爆片。SF6气体绝缘互感器的内绝缘具有很高的可靠性，一般情况下是不可能产生内部绝缘故障电弧的但考虑到不可预见的意外因素可能引起的内部电弧，作为设备的一种保安措施，特加装了防爆片。
外绝缘套管:220kV及以下产品采用高强度瓷套或高温硫化硅橡胶复合空心绝缘套管,可承受1.6MPa的额定压力(破坏压力>4.0MPa)。
产品底座内装设了SF6气体密度继电器，产品额定压力为0.4MPa,当产品内部压力为0.35MPa时，密度继电器发出报警信号;在0.30MPa时,密度继电器会再一次发出报警信号。六氣化硫(SF6)密度继电器具有自动温度补偿功能,在-40℃-+60C范围内指示的压力值是室温(20℃下的压力值(密度)。密度继电器配有专用单向自封阀，压力表拆除后，阀门自动关闭。
产品密封性能是SF6电器产品最关键的问题，产品采用了成熟的密封结构设计，严格的限位密封，采用优质的密封材料，同时为保证密封性能的长期性，采用了密封胶和防水胶，保证产品年泄露率在0.5%,确保产品长期安全运行。
一次接线端子采用整体压铸成型，机械强度高。
The product adopts an inverted structure and consists of the following components: shell, explosion-proof disc, transformer body, bushing, base, and density relay. Inside the product, there are shielding components that improve the electric field. The secondary leads are connected to a sealed terminal box, and the shell is available in two types: three-way shell and bell-jar shell.
• Main Insulation: The main insulation uses a coaxial cylindrical uniform electric field structure. The primary conductor rods and secondary shields together form a coaxial cylindrical uniform electric field. To change the current ratio, the primary winding can be connected in series or parallel, and all transformation ratios can be obtained from the secondary tap.
• Explosion-Proof Disc: An explosion-proof disc is installed at the upper part of the shell. Although the internal insulation of the SF6 gas-insulated transformer is highly reliable and typically does not cause internal insulation fault arcs, an explosion-proof disc is included as a safety measure in case of unforeseen internal electric arcs.
• External Insulating Bushing: For products rated 220kV and below, the exteral insulating bushing uses high-strength porcelain bushings or high-temperature vulcanized silicone rubber composite hollow insulator bushings, which can withstand a rated pressure of 1.6MPa (breaking pressure >4.0MPa).
• Base and SF6 Gas Density Relay: The base contains an SF6 gas density relay. The product's rated pressure is 0.4MPa, and the density relay emits an alarm signal when the intemal pressure reaches 0.35MPa. If the pressure drops further to 0.30MPa, the relay will trigger another alarm signal. The SF6 gas density relay has automatic temperature compensation, and the pressure readings between -40°C to +60°C are adjusted to the equivalent pressure at room temperature (20°C).
• Sealing: Sealing is a critical issue for SF6 electrical products. The product adopts a mature sealing structure design, strict sealing limits, and high-quality sealing materials. To ensure the long-term sealing performance, sealing glue and waterproof glue are used, guaranteeing a leakage rate of less than 0.5% per year and ensuring the product' s long-term safe operation.
• Primary Terminal: The primary terminal is formed by an integrated die-casting process, providing high mechanical strength.
This structure design ensures high reliability, safety, and minimal maintenance while meeting the demands of modern power grid applications.
