4. Product Introduction

4.1 AITR Series Isolation Transformer

AITR series isolation transformer is specially used in medical IT system. The core of the product is made of silicon steel sheet imported from Japan, and the loss is very small. Double insulation treatment is adopted between windings and windings, and an electrostatic shielding layer is designed to minimize the electromagnetic interference between the two windings. PT100 temperature sensor is installed in the winding, which can be used to monitor the winding temperature. The transformer is treated by vacuum impregnation, which increases the mechanical strength and has anti-corrosion effect. In addition, the product also uses low temperature rise and low noise design, so that it has good temperature rise performance and low noise.

Model Selection Description

Any isolation transformer will generate inrush current at start time ,Therefore, for the medical IT systems consisting of the medical isolation transformer and insulation monitoring products,In selecting the circuit breaker which is installed in the line circuit into an isolation transformer,it Shall meet the requirements of GB16895.24-2005 , Breaker has short-circuit protection and without overload protection (ie single magnetic circuit breaker),Such as ordinary breaker should be selected in line with GB14048.2-2008 of C, D circuit breaker tripping curves,And the rated current should be determined according to the following relationship with isolation transformer capacity: 10kVA-63A, 8kVA-50A, 6.3/5kVA-40A, 3.15kVA-20A,The purpose is to prevent the impact of the current   circuit breaker switching difficulties or safety-power tripping, resulting in serious medical malpractice when isolation transformer to power or dual power operation.
