電動機保護用高壓限流熔斷器
電動機保護用高壓限流熔斷器
注:1.以上是單管額定參數,可根據用戶需要采用固定結構將熔斷器并聯(lián),以得到高的額定電流值。
Note:1.The aboveid rated parameters for single pipe,the fuses can be parallel connected by fixed structure to geta high rated current.
2.Sizes in the bracket are for inserting fuses.
□本產品適用于戶內交流50Hz,額定電壓為3.6KV、7.2KV、12KV、24KV、40.5KV系統(tǒng),可與其它開關、電器如負荷開關、真空接觸器配合使用,作為電力變壓器及其它電器設備短路、過載的保護元件,又是高壓開關框、環(huán)網框、高、低壓預裝式變電站必備的配套產品。
