美式箱变高压侧由后备保护熔断器和插入式熔断器串联提供全范围保护，原理简单，经济可靠；后备保护熔断器为油浸式高压限流熔断器，开断容量大，仅在
变压器内部故障时动作，插入式熔断器内装双敏熔丝，可提供电流与温度双重保护，双敏熔丝熔断后，可在现场方便地更换熔芯。
The US box-type high-pressure side by the backup protection fuse and plug-in fuse in series to provide full range of protection, the principle is simple and
economical and reliable; backup protection fuse for the oil-immersed high-voltage current limiting fuse, breaking capacity, only in the transformer Fault action,
plug-in fuse built-in dual-sensitive fuse, can provide current and temperature dual protection, unika fuse blown, can be easily replaced in the field melting core.

箱变结构 /Box variable structure
该产品箱体结构由高压间隔、低压间隔、油箱间隔三部份组成。高压间隔内包括高压电缆附件、负荷开关、无载调压分接开关、插入式熔断器、压力释放阀、油位计、
油温计、放油阀。低压间隔内包括低压套管、低压计量表计、断路器、电容补偿。油箱间隔内包括变压器绕组和铁芯、散热器、高压负荷开关及熔断器均在油箱内，
根据方案需要箱变结构可设计成品字型或目字型见下图。
The product box structure by the high-pressure interval, low pressure interval, fuel tank interval composed of three parts. High voltage interval includes high
voltage cable accessories, load switch, no load tap changer, plug-in fuse, pressure relief valve, oil level gauge, oil temperature gauge, oil drain valve. Low-
voltage interval, including low-voltage casing, low-pressure meter, circuit breaker, capacitor compensation. The fuel tank interval includes transformer winding
and core, radiator, high pressure load switch and fuse are in the tank, according to the program needs box variable structure can be designed finished font or
