Cabinet DescriptionProduct OverviewThe medical isolation
transformer built in ZWM-1/3P series system cabinet is
designed for medical occasions that require high-efficiency and
low-noise isolation power supply, as well as for noise-sensitive
medical instruments and precision measuring equipment.
Features1,The isolated power grid is completely independent of the
power grid for power supply, which actively ensures the electrical
safety; 2,The isolation power supply can generate new neutral line,
which can avoid the operation defect of the equipment caused by the
defective neutral line of the power grid; 3,The distortion of
current waveform caused by nonlinear load in power grid can be
isolated without being polluted by the power grid; 4,Real-time
detection of the insulation resistance, power load and power grid
output voltage after high-temperature tension isolation of
isolation transformer in single-phase or three-phase isolated power
grid; 5, Strict application of operation noise control
technology to minimize noise; Product

considerations: 1, ZWM-1/3P series isolation power supply
system, whether used in operating room, ICU, ICU ward or delivery
room, must be designed with short-circuit protection and no
overload tripping function. 2, The medical isolation
transformer in ZWM-1/3P isolation power supply cabinet shall
have the function of automatic heat dissipation and cooling. If the
temperature does not drop, it shall have an over-temperature alarm
to remind the electrician on duty for handling and maintenance in
time to ensure electrical safety. 3,The insulation monitoring
instrument must directly display the insulation value and the lower
alarm limit, the voltage value after isolation, the upper and lower
voltage limits, and the double temperature values. The first
temperature is for starting heat dissipation system, and the second
temperature is the upper alarm limit, and the insulation monitoring
instrument is equipped with an audible and visual alarm, which can
draw attention in case of failure. 4,More than 2 sets of
medical IT isolation power supply system (simple) and external
alarm test and display instrument (centralized display)
5,Difference between UPS and medical IT system UPS is the
backup emergency power supply when the power of the normal power
supply line is interrupted, and it can't prevent the leakage fault.
When the load side of the common grounding system (YN-S) is with a
grounding fault, no matter whether the system uses the UPS or the
common power supply line, it can't limit the increase of the fault
current. Only by adopting the IT system can the fault current be
limited to the maximum extent, so as to achieve the purpose of
protecting patients. Structure Diagram of CabinetCircuit
