fuse disconnect switch(DS) outdoor high voltage isolate switch is the high voltage switch equipment of composite strudcture, is suitable for outdoor 22KV line net with voltageand no load, to make opening and close. With type manual operate machinery, can avoid earth line with power and composite flash-locks ets.
A current transformer (CT) is a type of transformer that is used to reduce or multiply an alternating current (AC). It produces a current in its secondary which is proportional to the current in its primary. Current transformers, along with voltage or potential transformers, are instrument transformers.
A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to “step up” or “step down” voltages and works on the magnetic induction principle. … A voltage is then induced in the other coil, called the secondary or output coil.
Drop out fuses and load-drop fuses are outdoor high voltage protection appliances. It is installed on the high voltage side of the distribution transformer or on the branch line of the distribution line. used as a short circuit of the transformer and the line, overload protection and split load current.
