一、产品描述（Product Description）
中文描述
在35kV户内配电系统中，雷击引发的大气过电压、设备启停及开关操作产生的操作过电压，是导致核心电气设备损坏、线路故障、生产中断的主要隐患，不仅影响电力供应稳定性，还会造成巨大的经济损失。TBP-B-42F-310 金属氧化物避雷器，以“全维度防护、高效可靠、适配性强”为核心，针对配电、电站场景量身打造，为35kV户内配电系统提供全方位的过电压解决方案，弥补传统避雷器仅能保护相对地的短板。
产品核心元件采用以氧化锌为主的专用配方电阻片，具备优异的非线性伏安特性，正常工作电压下，通过的电流仅为微安级，不影响系统正常运行；当遭遇过电压时，电阻片瞬间转为低阻态，电流瞬间达到数千安培，快速导通并释放过电压能量，将电压钳位在设备耐受范围内，有效保护设备绝缘不受侵害。相较于传统碳化硅避雷器，本品具有陡波响应无延迟、操作残压低、无放电分散性等优势，大幅提升陡波、雷电波、操作波下的保护裕度，防护性能更全面。
TBP-B-42F-310采用三相四星型接线（A、B、C三相+中性点N接地），单台设备即可实现6个保护通道（3相地+3相间），相当于六台普通避雷器的保护效果，大幅节约安装空间与成本。设备采用整体模压成型工艺，复合外套密封性能优良，具备良好的防爆、防潮、抗漏痕、抗电蚀性能，憎水性强、耐污能力突出，无需定期清洗维护，有效减少雾天湿闪现象的发生。同时，产品体积小、重量轻，耐碰撞、运输无碰损，可垂直或水平安装，适配KYN、XGN、GBC、JYN、GZS等不同型号的中压成套开关柜，也可直接安装在小型箱式变电站内，安装灵活便捷。
本品执行GB11032-2000、JB/T8952-2005等国家标准，实配直流参考电压、方波通流容量和大电流耐受能力均高于国家标准，泄漏电流小、老化速度慢，使用寿命长。广泛应用于电厂、工矿企业、变电站的35kV户内配电系统，主要保护变压器、开关、母线、电动机、发电机、线路、电容器组等电气设备，尤其适合真空开关频繁操作的配电系统，为电力设备和配电系统的安全稳定运行保驾护航。
Description
In 35kV indoor power distribution systems, atmospheric overvoltage caused by lightning strikes and switching overvoltage generated by equipment start-stop and switch operation are the main hidden dangers leading to damage of core electrical equipment, line failures and production interruptions, which not only affect the stability of power supply, but also cause huge economic losses. TBP-B-42F-310 Metal Oxide Surge Arrester, with “comprehensive protection, high efficiency and reliability, strong adaptability” as the core, is tailored for power distribution and power station scenarios, providing a comprehensive overvoltage solution for 35kV indoor power distribution systems and making up for the shortcoming that traditional surge arresters can only protect phase-to-ground.
The core component of the product adopts a special formula resistor chip mainly composed of zinc oxide, which has excellent nonlinear volt-ampere characteristics. Under normal working voltage, the current passing through is only microampere level, which does not affect the normal operation of the system; when encountering overvoltage, the resistor chip instantly turns into a low-resistance state, the current reaches several thousand amperes in an instant, conducts quickly and releases overvoltage energy, clamping the voltage within the tolerance range of the equipment, and effectively protecting the equipment insulation from damage. Compared with traditional silicon carbide surge arresters, this product has the advantages of no delay in steep wave response, low operating residual voltage, no discharge dispersion, etc., which greatly improves the protection margin under steep waves, lightning waves and switching waves, and the protection performance is more comprehensive.
TBP-B-42F-310 adopts three-phase four-star connection (一個, B, C three phases + neutral point N grounding), and a single device can realize 6 protection channels (3 phase-to-ground + 3 phase-to-phase), which is equivalent to the protection effect of six ordinary surge arresters, greatly saving installation space and cost. The device adopts integral molding technology, the composite jacket has excellent sealing performance, good explosion-proof, moisture-proof, anti-leakage, anti-electrical corrosion performance, strong hydrophobicity and outstanding pollution resistance, no regular cleaning and maintenance is required, and the occurrence of wet flash in foggy days is effectively reduced. 同時, the product is small in size, light in weight, collision-resistant, no damage during transportation, can be installed vertically or horizontally, suitable for various models of medium-voltage switchgear such as KYN, XGN, GBC, JYN, GZS, and can also be directly installed in small box-type substations, with flexible and convenient installation.
This product implements national standards such as GB11032-2000 and JB/T8952-2005. The actual matching DC reference voltage, square wave current capacity and high current tolerance are higher than national standards, with small leakage current, slow aging speed and long service life. It is widely used in 35kV indoor power distribution systems of power plants, industrial and mining enterprises and substations, mainly protecting electrical equipment such as transformers, switches, busbars, motors, generators, lines and capacitor banks. It is especially suitable for power distribution systems with frequent operation of vacuum switches, escorting the safe and stable operation of electrical equipment and power distribution systems.
