医疗设备安全隔离变压器

Medical equipment safety
isolation transformer

▁ 产品概述 /Product overview

本公司开发的医疗安全隔离变压器在 DG 控制变压器基础上，经过多年来进一步吸收国外同类产品，并优选国外先进方法的接线端子结构、
将端子与骨架合在一起，使防护等级提高到 IP2LX。防止偶然触及电路。采用国内 IT 冷压接线端子，接线方式可以使接线密集程度提高。

变压器任一绕组的额定电压不超过 500V 时，均通过 5 倍压 5 倍频试验 , 线圈内部增加了进口温度保护开关（热敏动断开关）。在使用时，
其热敏动断常闭触点应串入二次控制回路，才能起到保护作用。 当设备使用不当变压器过热， 温度保护开关就会动作，断开控制回路或报警，
只要当变压器线圈的温度下降到一定值时，温度保护开关自动复位后， 才可以将设备重新起动起来。
产品符合 :GB9706.1-2007,IEC60364-7-710 IEC61558 应用在各种医疗设备中，例如激光仪器设备、扫描仪、X 射线设备、C 型臂、超
声波设备、心电图设备、核磁共振设备、临床检验分析仪器、牙科仪器和其他诊断仪器等。
On the basis of DG control transformer, the medical safety isolation transformer developed by our company has further absorbed similar
foreign products over the years, optimized the wiring terminal structure of foreign advanced methods, combined the terminal and the skeleton,
and improved the protection level to IP2LX. Prevent accidental contact with the circuit. Adopt domestic IT cold press wiring terminal, wiring
mode can make wiring density increase.
When the rated voltage of any winding of transformer does not exceed 500V, it will pass the test of 5 times voltage and 5 times frequency, and
the inlet temperature protection switch (thermosensitive dynamic break switch) is added inside the coil. When in use, the thermo-sensitive
moving normally closed contact should be connected to the secondary control loop in order to play a protective role. When the transformer is
overheated due to improper use of the equipment, the temperature protection switch will operate, disconnect the control loop or give an alarm.
As long as the temperature of the transformer coil drops to a certain value, the temperature protection switch will automatically reset before
starting the equipment again.
Products conform to: gb9706.1-2007, iec60364-7-710 IEC61558 is used in various medical equipment, such as laser equipment, scanners, X-ray
equipment, c-arm, ultrasonic equipment, electrocardiogram equipment, nuclear magnetic resonance equipment, clinical examination and
analysis instruments, dental instruments and other diagnostic instruments.
