Medical Isolation Power Supply System

Overview

Medical IT system insulation monitoring device and fault location system is suitable for hospital operating room, ICU (CCU) and other important places, and can provide a safe place for such continuous, reliable power solutions.
Due to growing demands of electronic medical equipment from hospitals, the request of protection for patients from the threat of residual current became the most crucial parts of hospital isolated power supply system.

Applicaiton Scenarios

(1) According to IEC 60364-7-710：2002, hospital medical locations could be devided into Group 0, Group 1 and Group 2 locations. ["Group 2 Medical Location" refers to locations where the applied parts of medical electrical equipment are intended to be in direct contact with patients, and where continuity of power supply is critical. This includes areas like operating theaters, intensive care units [ICU], and other critical care areas.]
(2) A IT power system instead of TN-S system will be used for Group 2 medical locations. [So that no potential leakage current threat happened to vulnerable patients by embeded electrical medical equipment.]
(3) The insulation monitoring, alarm and fault detection for IT power system will be necessary to ensure the whole IT power system's normal running and maintanence.

Judging by application scenario and function requirement, solution could be devided into 4 basic solution:

(1) Functional/Economic Insulation Monitoring&Alarm Solution for Operation Room [with/ without insulation fault location function]

(2) Functional/Economic Insulation Monitoring&Alarm Solution for ICU, NICU, CCU, etc. [with /without insulation fault location function]

• Scenario Preset [Opearting Room Insulation Monitoring&Alarm solution with Fault Location]

(1) The target was to monitor one IT power system in the operating room of a hospital. [including insulation level of IT power system, temperature of isolation transformer, current of load and etc.]

(2) Rated voltage of IT power system was 230Vac.

(3) 6.3kVA will be enough for the overall IT power system.

(4) There are 6 1-phase sub circuits [for 6 different medical load respectively] to power up the important equipment in this IT power system. Also, insulation fault location function was requested.
