  • Three-phase oil-immersed isolation transformer

    I. Overview of three-phase oil-immersed isolation transformer The transformer is a new generation of energy-saving power transformer developed and produced by our factory with reference to similar international products and based on China's national conditions. From 300VA to 1600KVA, it conforms to IEC439, GB5226 and other international According to national standards, the winding adopts the whole winding method; the transformer is vacuum dipped to make the transformer's insulation level reach F or H level, and the product performance reaches the advanced level at home and abroad. GSG series three-phase dry isolation transformers are widely used in circuits with AC 50Hz to 60Hz and voltage below 660V, and are widely used in importing important equipment, precision machine tools, mechanical and electronic equipment, medical equipment, rectifiers, lighting, etc. Various input and output voltage levels of the product, connection group, number and position of adjustment taps (usually ± 5%), distribution of winding capacity, provision of secondary single-phase windings, use of rectifier circuits, whether belts are required The shell, etc., can be carefully designed and manufactured according to user requirements. Second, product characteristics: The establishment of a new neutral line in the transformer-grounding can relieve the common mode interference and other neutral line problems in the power grid. The isolation transformer converts the three-wire delta connection to a four-wire Yo system, and the shielding further eliminates the high coupling by the transformer internal coupling. Frequency pulse interference and noise, although shielded isolation transformers can effectively prevent various NG interference (pulse and high frequency noise), but the transformer must be properly and properly grounded and very strict, otherwise anti-common mode interference will have no effect. The company can design and produce high-quality isolation transformers for customers. 3. Feature advantages 1. High isolation 2. Good NG performance 3. High common mode interference suppression 4. Convert △ to Y or Y to △ 5. The voltage tap is easy to convert 6. Designed according to the special performance requirements of the user. IV.

Regarding the isolated power supply Note: The principle, structure and advantages of the three-phase oil-immersed isolation transformer. characteristic. Each winding on the primary and secondary sides is divided into two coils, and the two coils are wound with two layers of metal foil insulated from each other. There is then a capacitance C (ie, a capacitive isolation transformer) between the two coils. Then you can take any combination of the following two wiring methods according to your needs: 1. It has a voltage conversion function (such as: △ / Yo or Yo / △ connection method) 2. It has a filter anti-interference function (such as: it can remove the third harmonic interference function). Can remove odd-order harmonic interference.) 3, can effectively suppress the disturbance harmonics and lightning electromagnetic pulses introduced from the power line to interfere with the system; 4, can effectively suppress the disturbance harmonics emitted by the electronic equipment of the system into the power distribution Electrical network interferes with other equipment (devices and systems); 5, can fundamentally prevent system malfunction, data loss or error caused by ground potential disturbances; 6, can effectively prevent building lightning protection devices from flashing Due to the sharp rise of the steel bar potential as a reference ground, the hardware equipment in the system was counterattacked and destroyed. > Company product service guarantee: Before each product is shipped, all products are strictly inspected in accordance with national standards to ensure a qualified rate.
