isolation transformer

Medical toroidal transformers, also known as isolated power supply systems, are widely used in the medical field. 1. Because the isolation transformer reduces the contact voltage and the current from the grid to the ground, the risk of being electrocuted is minimized. 2. Isolation transformer can effectively reduce ground leakage current and improve fire safety. 3, to ensure the continuity of power supply, when the insulation fault, will not easily cause the power trip.

Output transformer: used in audio equipment and broadcasting equipment, plays the role of impedance transformation in the circuit. Input transformer: the main function is in the input of sound signal when the occurrence of impedance conversion in the circuit. Interstage transformer: a common interstage transformer enables the various operating units in an amplifier to harmonize. Wire-to-wire transformer: wire-to-wire transformers are often used in wired broadcast equipment. Due to the cable broadcast on the work unit, there are often a lot of power amplifier, and the long lines, long distance transmission of audio will make the audio distortion. The structure of the ring audio transformer has high utilization rate, high stability, low loss and strong load capacity. Therefore, toroidal audio transformer is very suitable for installation in broadcast system.

The Features of Single-Phase Isolation Low-Frequency Toroidal Transformer: (1) High efficiency. -It is product by high quality material and the type is compact. It can narrow the gap between the coil and the core. So the efficiency is above 95% (2) Low magnetic flux leakage. -The gap between core and coil is small and the coil is unformly. (3) Low noise and low temperature. -Due to the high quality material and the coil is unformly, the resistance loss and the fever is very low.

Toroidal isolation transformer: Safety -- the secondary of the isolation transformer is not connected with the earth, and the toroidal isolation transformer's output is "floating ground". When people touch any line of the secondary of the isolation transformer, they will not get electric shock because they cannot form a current loop. Prevent power electronic devices from polluting the power grid - transformers have a great attenuation effect on high-frequency harmonics, so power electronic devices can avoid polluting the power grid.

Advantages 1. The toroidal transformer has a simple structure and can be flexibly designed; 2. The toroidal core is made of oriented silicon steel strip, which is a continuous closed magnetic circuit with high magnetic flux and small leakage inductance; 3. The toroidal core has low processing stress and can fully utilize the magnetic properties of the core material. Its magnetic property is better than those of other types; 4. Under the same electrical performance, the temperature rise is lower than that of other types, and has a longer service life; 5. For high-power transformers, it has the advantages of small size and high cost performance. 6.Wide application fields.

The medical toroidal transformer commonly used to provide suitable power to various medical and peripheral equipment. High efficiency, low loss; Small size and light weight; No noise, low temperature rise; Low leakage, double over current fuse; Multiple temperature protection switches; Power from 10 va - 10 kva; Custom design products for customers. Widely used in medical equipment, such as: scanner, X-ray machine, ultrasound, electrocardiogram, clinical testing equipment, dental equipment, cosmetic equipment, rehabilitation therapy equipment, operating bed and various diagnostic equipment.

Toroidal transformers used in medical electrical equipment are different from those used in general instruments and have many special requirements. 1. Toroidal transformers used in medical electrical equipment shall prevent their basic insulation, auxiliary insulation and reinforced insulation from overheating in case of short circuit or overload of any output winding. 2. Protective devices that are external to the transformer or outside the transformer housing to prevent overheating, such as fuses, over-current releasers, thermal circuit breakers, etc., shall be connected so that the protective devices will not become ineffective when any components other than the wiring between the protective devices and the transformers are damaged.
