SG/DG isolation transformer

Product description:
A, use SG series isolation lifting transformer is a kind of input/output isolation, and input/output are able to do 220 v and 380 v three-phase ac conversion utility alternating current power supply. Easy to use, safe and reliable. Whoever needs and network isolation, and the need for ac voltage conversion equipment all can use this product.
Second, the main technical indicators:
1. The maximum output capacity
2, input voltage: three-phase 220 v, 380 v option
3, output voltage: three-phase 220 v, 380 v option
4, power frequency: - hz
5, insulation resistance: > 5 m Ω
6, dielectric strength: the ac 2000 v1min withstand voltage test.

Three, structure features
First, second all use electromagnetic wire winding, transformer core are the heart type core, by electrical silicon steel sheet lap product and become, iron column using a multi step of circular cross section, the iron yoke with rectangular cross section, in the upper and lower iron yoke on both sides of the use of steel channel as a clamp parts, through the clip yoke screw in order to achieve the compacted iron yoke, upper and lower clamping piece using fasten screw fasten to achieve the use of fixed coil.


Four, working conditions
1, no more than 1000 meters above sea level pressure, such as more than 1000 meters, the standard according to the power transformer capacity reduced.
2, environmental temperature is not higher than + and ℃.
3, air relative humidity is not higher than 85%.
4, there is not a strong vibration and severely corrosive gas.

Five, the method of use
1, the user before use, must according to the transformer power choose proper power supply wire and local power grid voltage and transformer nameplate, power cord correct access input terminal.
2, the user root required voltage, the output wire access appropriate output terminal.
3, load shall not exceed the nameplate specified data.
4, check the input and output power line connection correct situation below can turn on the power switch.
5, this series by air switch, air switch after closing without corresponding ac voltage output, check the input and output wire connection is reliable.

Six, customize special gauge transformer input, output voltage and connection mode depending on the buyer's requirements set.
