◆新型高压限流熔断器产品特点 Product characteristics of new high-voltage limit-current fuse
我公司生产的高压限流熔断器,是在综合国内外同类产品基础上,研制出来具有世界先进水平的高品质产品, 该产品具有以下特点:
1、分断能力高,开断电流可达63KA。
2、功耗小、温升低。
3、动作特性快,安一秒特性要比国内目前生产的同类产品动作快,例如额定电流100A的熔断体,通以1000A预期电流,弧前时间不超0.1S
4、安一秒特性误差小于±10%。
5、配有弹簧式撞击器,该撞击器具有接触面大,压强小等优点。因此,在推动开关联锁动作时,不会产生将开关与撞针接触面打碎或击穿的情况发生。
6、规格标准化。
7、有较大的限流作用。
8、产品性能符合GBl5166.2国家标准及IEC60282-1国际标准。
9、能可靠开断最小开断电流至额定开断电流之间的任何故障电流。另外,还可根据用户需求,生产各类非标准产品。
The high-Volt current-limit fuse of our company are the high-quality products with world advanced leve which are developed on basis of absorbing the same product’s advantages domestical and abroad.This product owns the following characteristics:
1.with high broken-ability,the broken current can achieve 63KA.
2.Small power-consumption,low temperature-rising.
3.with fast motion properties.its ampere-second performance is faster than domestically produced product of same kind at
present.Taking fuse component with rated current being 100A for example,the pre-arc time doesn’t exceed 0.1 Sif electrified with
1000A anticipated current.
4.The ampere-second per for man ce erro r is with in±10%.
5.Matched with spring type collision device.this collision device own properties of big contacted surface and small intensity
of pressurc.Consequently,smashin gor puncturing switch and striker would not occur when operator pushes switch for link-lockmotion
6.Specification standardization.
7.Own big limit-current function.
8.The product’s performance is up to GBl5166.2 and IEC60282-1 standard.
9.Could break down reliably any fault current from minimum broken current to rated broken circuit.additionally our company could produce various non-standard product awording to user’s demand.
