The medical isolation power supply cabinet and insulation monitoring device are designed according to the different power distribution characteristics of the 2 types of medical places and are used to monitor the operating status of the medical IT system. Once a certain set of IT systems fails, electrical maintenance personnel can make a judgment within time and deal with it according to the on-site situation.
The power supply of the IT system should use an independent power source, such as a distribution/isolation transformer, generator set, battery and UPS. Isolation transformers are usually used more often. After the isolation transformer, it is the IT system. There is no direct connection between the live conductor and the ground in the IT system. The exposed conductive parts of all equipment must be connected to the ground. In a single-phase IT system, the secondary side of the transformer does not matter whether the phase line or the N line is divided. They are all live conductors.
