適用范圍及用途
高壓真空開關(guān)適用于具有爆炸性危險(xiǎn)氣體以及煤塵的礦井中。6kV/50Hz額定電流400A以下供電系統(tǒng)進(jìn)行控制和保護(hù)，真空開關(guān)可用于移動(dòng)變電站的高壓側(cè)與我廠生產(chǎn)的低壓保護(hù)箱或真空饋電開關(guān)構(gòu)成移動(dòng)變電站，對(duì)變壓器容量315kVA—1600kVA配套，對(duì)系統(tǒng)的過(guò)載、短路、斷相、過(guò)壓、欠壓等故障以及低壓側(cè)故障進(jìn)行保護(hù)。
Applications
The high-voltage vacuum switch is suitable for control and protection of the 6kV/50Hz power supply system under the mine well with explosive dangerous gases and coal soot, with the rated current of 400A. Besides, it’s suitable to constitute another mobile transformer substation with the high-voltage side of the mobile transformer substation and low-voltage protection box or vacuum feeding switch produced by our factory, to support the transformer with capacity of 315kVA~1600kVA, and protect the system in case of overload, short circuit, phase failure, overvoltage, undervoltage etc. and other failures in the low-voltage side.
