户内高压SF6断路器LN2-10KV11.5KV/1250A
LN2-10KV11.5A/1250A户内高压SF6断路器适用于交流50Hz，额定工作电压10kV，额定工作电流1250A电力系统中，作为各种用电负荷控制和保护的户内开关设备使用。
型号含义
结构特点
固定式的LN2-10型断路器三相装于一个底箱上，内部有一根三相连动轴，通过三个主拐臂带动绝缘拉杆，从而推动导电杆上下运动达到合闸和分闸。手车式LN2-10型断路器系将固定式断路器装于车上，并加装支持绝缘子，配装CT8弹簧操动机构，实现了断路器及操动机构一体化。
LN2-10型断路器内绝缘采用SF6气体。其灭弧原理采用了旋弧纵吹式与压气式相结合的高效灭弧方式，即当电弧从弧触指转移到环形电极上时，电弧电流通过环形电极流过线圈产生磁场，磁场和电弧电流相互作用使电弧旋转，同时加热气体，压力升高，并在喷口形成高效气流，将电弧冷却，当介质恢复足够时，电弧在电流过零时熄灭。
适用工作条件
（1）海拔高度不超过1000m；
（2）环境温度不高于40℃，不低于-5℃；
（3）相对湿度不大于90℃（20℃时）；
（4）没有火灾、爆炸危险，无严重腐蚀金属和绝缘材料的化学气体或蒸气的场所；
（5）没有剧烈震动的场所。
Description
Tapecoat TC® 7100 Wet Bond Gray Epoxy is a surface tolerant epoxy developed for coating metal and concrete above and below fresh water. It provides an exceptional anti-corrosion coating for protecting bare steel, welded joints on factory-coated pipe, irregular fittings and surfaces.
TC 7100 is an innovative coating which can be applied underwater for the repair of damaged coatings on steel transmission pipes; steel, concrete, and sheet pilings; and lateral supports. It is ideal for above and below ground protection of metallic surfaces on pipes and compressor / pumping stations that endure splashes, condensation, or humidity.
TC 7100 is a two-part liquid epoxy system which can be used on damp, wet or dry metal surfaces as a one-coat stand-alone protective coating system for above and below grade application.
Specifications
Basic Use
TC 7100 Wet bond-Gray is a corrosion preventive epoxy coating developed for coating metal and concrete surfaces above and below the water line. It is used to repair pipeline coatings, for coating irregular fittings and surfaces and is suitable for above and below ground as well as underwater applications.

Surface Preparation
Remove all contaminants that would impede bond. Use effective cleaning procedures to remove: salts, rust, dirt, oil and grease. This may include the use of high pressure fresh water cleaning, using suitable solvents or detergents to SSPC-SP-1, abrasive blast to SSPC-SP-6, or wire brush clean to SSPC-SP-2.
Application
Environment: Use only where application and curing can proceed at temperatures above 40°F (4°C). The temperature of the surface and that of the coating itself must also be within these limits. Apply only on a clean surface. (See detailed Field Specifications for complete instructions.)
Mixing: Pour entire contents of hardener container into the resin container and mix thoroughly until homogeneously mixed, approx. 3-5 minutes.
Application Method: Apply epoxy by brush, pad or roller.
