WORKING CONDITIONS
1. Altitude: no more than 2000M.
2. Ambient temperature: high temperature: +40ºC; Low temperature: -45ºC : high monthly average temperature: +30ºC : high annual average temperature: +20ºC;
3, installation environment: no explosive, corrosive liquid, gas and dust, installation site without violent shock, allowed in a certain period of time Or run completely submerged in water.
4. Ground acceleration induced by earthquake Ag; The horizontal direction is lower than 3m/s; The vertical direction is lower than 1.5m/s.
5, the waveform of the power supply voltage: approximately sine wave.
6, three-phase power supply symmetry: for three-phase underground transformer, three-phase power supply voltage should be roughly symmetrical.
