2. Product Overview
The product introduced here is a three phase photovoltaic transformer with 25KVA rated capacity. Its input voltage is 380V or 400V. Its output voltage is 380V or 400V too. It is mainly used in photovoltaic power generation. The photovoltaic panel collects the direct current, which is transformed into alternative current through an inverter. However, the alternative current transformed through the inverter is not purified. It is full of impurities. Under this circumstance, the three phase isolation transformer would function in eliminating all the impurities and get the alternative current purified. In this way, the alternative current could be connected to the power grid. So three phase isolation transformer is an important part in photovoltaic power generation.
3. Product Features
| Anti-interference | The transformer is an isolation transformer, which could effectively reduce the interference of harmonics. |
| Safety | Because the primary winding is separated from the secondary one, the transformer is designed for the users' safety. |
| Time relay design | There is a time relay with this transformer, through which you could set the time to power on and power off. |
| Full capacity | The rated capacity of this transformer is 25KVA, which is full capacity. |
| Clear input and output display | The primary and secondary voltage is clearly shown on the pointer meters. |
4. Pre-shipping Tests
Before leaving the factory, every product should pass a series of
vigorous tests, performed with various measurements.
| Necessary Tests | |
| Appearance (enclosure, windings, small parts) | Insulation resistance |
| Winding resistance | Voltage ratio check |
| Short circuit impedance and load loss | No load loss and current |
| Optional Tests | |
| Temperature rise test | Efficiency |
| Connection method | Inrush current test |
| Waterproof test | Frequency |
There are necessary tests and optional tests. If you have any special requirement, please tell us in advance.
