3、IT 隔离电源系统简介及医院采用的重要性 Introduction of IT isolated power system and importance of hospital adoption
1）IT隔离电源系统，I表示电源侧没有工作接地，或经过高阻抗接地。T 表示负载侧电气设备进行接地保护。IT系统在供电距离不是很长时，供电的可靠性高、安全性好。一般用于不允许停电的场所，或者是要求严格地连续供电的地方，医院的手术室、急救室和ICU室等二类场所必须采用IT系统。运用IT方式供电系统，即电源中性点不接地，一旦设备漏电，单相对地漏电电流很小，不会破坏电源电压的平衡，因此可以避免电击等电气事故，同时不足以使回路保护电器动作切断电源，保证供电的不间断。所以比电源中性点接地的系统安全、可靠。
IT isolates the power system, and I indicates that the power side is not working grounded, or is grounded through high impedance.T represents the grounding protection of the electrical and gas equipment at the load side.IT system in the power supply distance is not very long, the reliability of power supply is high, good security.Generally used in places where blackouts are not allowed, or where strict continuous power supply is required, IT systems must be used in hospital operating rooms, emergency rooms, ICU rooms, and other type ii places.The use of IT mode power supply system, that is, the neutral point of the power supply is not grounded, once the equipment leakage, single-phase leakage current to the ground is very small, will not destroy the balance of the power supply voltage, so IT can avoid electric shock and other electrical accidents, at the same time is not enough to make the circuit protection electrical equipment action cut off the power supply, to ensure the uninterrupted power supply.So than the power neutral grounding system is safe and reliable.
2）医院使用隔离电源系统的重要性和必要性。
The importance and necessity of using isolated power systems in hospitals.
众所周知，当用电设备对人体心脏直接漏电大于10uA 时，会造成对病人的微电击事故。
而在一般通用建筑中所采用的对地漏电保护开关，其动作响应值是mA 级（如：30 mA），远远不能满足医疗领域的需要。在医院的特殊环境里，漏电流对病人构成了潜在的危险，因此对电气安全设计也提出了特殊的要求。尤其是那些生命攸关的场所，如外科手术室、重症监护室、心脏手术室等地均需安装医用IT隔离电源系统，其目的就是为了保证对该场所内的医疗电器提供一个安全可靠的电源，以确保病人的安全。在导电体触及到心脏(例如，打开心脏的手术或埋置心脏起搏器)时，在普通安全接地的导体之间流过的细微电流会造成微电击和死亡的可能。隔离变压器就象一个门一样，将医疗地区的非保护区域和保护区域的电气线路隔开，保护区域内所有带电导体是与地隔离的，防止线路绝缘层上危险电流造成微电击。绝缘监视仪必须与隔离变压器配合使用，用来连续监视隔离变压器二次侧的带电导体与地之间的电阻及电流，例如，手术过程中流出体外的血液和金属制的手术台可能会使病人与地形成一个通路，这样就存在预期危险电流，一旦医疗电子设备的导电体也形成对地通路(如漏电)，将会造成宏电击(不是所有电流都流经心脏)或微电击(所有电流都流经心脏)。一般供电电网是以大地作为参考电位，相线中的电流可以通过任何未绝缘的通道，对地构成回路，这是电击的根本原因。隔离供电是采用隔离变压器供电，电源经隔离变压器后，原电网中的地已不再是参考电位了。隔离变压器任何一根输出线都不能与地构成回路，只能在两根输出线之间构成回路，这就提高了供电的可靠性。用隔离变压器以分隔非保护区域与保护区域，在隔离变压器的次级引出IT系统的电源，以防止产生接地故障电流。将IT系统引入手术室或急救室，在房间内设一配电箱，箱内放置绝缘监视仪，绝缘监视仪的使用可以及早的显示隔离变压器次级负载部分的绝缘状况，在发生绝缘故障对人身构成威胁前就提供报警信号。而此时电源不会被切断，保证了供电的连续性，医护人员此时可以根据监视仪上显示的漏电流大小和手术的实际情况及时处理，因而人身触电的危险被降低到了最小。
It is well known that when the direct leakage of electrical equipment to the human heart is greater than 10uA, it will cause a micro-shock accident to the patient.
However, the action response value of the earth leakage protection switch used in general general buildings is mA level (such as: 30 mA), which is far from meeting the needs of the medical field.In the special environment of hospital, leakage current poses a potential danger to patients, so special requirements are put forward for electrical safety design.In particular, those vital places, such as surgical operating rooms, intensive care units, cardiac operating rooms, etc., need to install medical IT isolation power system, the purpose of which is to ensure a safe and reliable power supply to medical appliances in the site, so as to ensure the safety of patients.When the conductor touches the heart (for example, during open-heart surgery or embedding a pacemaker), the tiny currents flowing between normally safely grounded conductors can cause micro-shocks and the possibility of death.The isolation transformer acts as a door separating the non-protected area of the medical area from the electrical wiring in the protected area. All live conductors in the protected area are isolated from the ground to prevent the dangerous current on the line insulation from causing a micro-shock.Insulation monitors must be used together with the isolation transformer, used for continuous monitoring isolation transformer secondary side of charged conductor and earth between the resistance and current, for example, in the process of the operation flow of blood and in vitro metal table may make the patient and to form a path, so there are dangerous currents, once the conductor in the medical electronic equipment form of pathways (such as leakage), will cause the macro electric shock (not all current flows through the heart) or micro electric shock (all electric current flows through the heart).Generally, the power supply network takes the ground as the reference potential, and the current in the phase line can pass through any uninsulated channel to form a circuit to the ground, which is the root cause of electric shock.Isolated power supply is the use of isolated transformer power supply, power through the isolated transformer, the original grid is no longer a reference potential.None of the output lines of the isolating transformer can form a circuit with the ground, but can only form a circuit between two output lines, which improves the reliability of power supply.The isolating transformer is used to separate the unprotected area from the protected area, and the power of the IT system is extracted at the secondary of the isolating transformer to prevent the generation of ground fault current.The IT system will be introduced into the operating room or emergency room, and a distribution box will be set in the room, and insulation monitors will be placed in the box. The use of insulation monitors can show the insulation status of the secondary load part of the isolation transformer as early as possible, and alarm signals will be provided before the insulation failure poses a threat to the person.At this time, the power will not be cut off, to ensure the continuity of power supply.Medical staff can then monitor the leakage current and the actual operation, so that the risk of personal shock is minimized.

5、IT 隔离电源系统有以下优点:
IT isolated power system has the following advantages:
1）触电电压和漏电电流很小，不足以引发电击或其它电气事故；
1) The shock voltage and leakage current are too small to cause electric shock or other electrical accidents;
2）供电系统出现对地故障时，不会导致回路保护电器动作切断电源，保证了供电的不间断。
2) In case of ground fault of the power supply system, the circuit protection device will not cut off the power supply, which ensures the uninterrupted power supply.
6、采用IT隔离电源系统的注意事项
Precautions for using IT to isolate power systems.
1）IT 系统不能引出中性线，因为在中性线发生接地故障时绝缘监测仪无法故障报警，系统将变为 TT 或 TN 系统，再发生相线接地故障，则系统电源将被切断，可能会产生严重后果。
1) The IT system cannot lead out the neutral wire, because the insulation monitor cannot give an alarm when the neutral wire has ground fault, and the system will
If TT or TN system is changed, the power supply of the system will be cut off if the phase-to-ground fault occurs again, which may have serious consequences.
2）由于 IT 系统发生一相接地时，另两相对低电压将升高，因此对电气线路及电气设备绝缘水平要求较高。
2) The other two relatively low voltages will increase when the IT system is connected to the ground, so the electrical circuits and electrical equipment are insulated, the level is high.
3）IT 系统的绝缘监测仪需通过 PE 线接地，因此其与PE线的连接必须可靠。
3) The insulation monitor of the IT system needs to be grounded through the PE wire, so its connection with the PE wire must be reliable.
