Hainuo brand oil-immersed rectifier transformer
>1. Product introduction
>Series of rectifier transformers produced by Shandong Chenyu Electric Co., Ltd.
are used as power transformers for rectifier devices.
, its function is to provide AC power to the rectifier, and the rectifier converts the AC power into DC power to provide DC power supply. Mainly used in metallurgy, chemical industry, locomotive traction and transmission industries
Technically, we have absorbed the successful experience of the French Alstom Company. We have selected high-performance silicon steel sheets and high-quality oxygen-free copper as materials. We have adopted advanced coil phase separation package technology, lead cold crimping technology, and oil tank sealing in production. Surface precision processing technology enables the product to have the advantages of energy saving, low loss, low noise, strong impact resistance and short circuit resistance, strong overload capability, compact structure, small size, reliable power supply, etc., and can meet various special requirements of users.
>Stable electrical performance
The product combines the load characteristics, grid voltage fluctuations and atmospheric overvoltage conditions, and determines a reasonable and reliable insulation level and insulation model according to the load condition of the rectifier transformer to ensure the electrical performance of the product Reliable and stable. Product environmental safety factor.
>(
) The windings of products with high dynamic stability have high mechanical strength and strong anti-sudden ability to meet extremely harsh load environments. In the design and manufacturing process, sources of dynamic instability caused by magnetic flux leakage of the transformer or that may be caused by abnormal transportation are better eliminated. The product has high dynamic stability. High impedance, higher than the impedance of a power transformer of the same capacity to suppress / effectively protect the rectifier components.
>Good thermal stability
Advanced product design, strictly control the temperature rise of the heating parts and hottest spots of the product, and leave sufficient temperature rise margin. If necessary, axial For the oil passage, the cooling method is selected according to the coil load loss value and the oil flow is reasonably distributed to achieve the best cooling effect. The main temperature rise indicators are at least ℃ lower than the national standard. Coils and leads are made of copper wires, and the current density is chosen to be low.
>Strong overload capacity
The product has strong overload capacity and overvoltage capacity, and can operate safely for a long time under rated load conditions, and can operate safely for a long time at full load under overvoltage conditions (ambient temperature ℃ ) The terminals connecting the transformer and the motor can withstand the rated current for a period of time. Product design and manufacturing fully consider load characteristics and meet overload requirements from various aspects such as temperature rise, insulation performance and accessory selection.
>Superior performance index
The no-load current design and manufacturing value are lower than the national standard specified value of the same capacity series transformer, which fully maximizes the economy and reliability of user use.
>The power saving effect is obvious and the noise is low (<).
>2. Structural Features
>Iron core
Made of high-quality cold-rolled silicon steel sheets, and at the same time, it adopts the selected step-by-step multi-stage lamination method, which greatly reduces the no-load loss. No-load current and noise.
>Winding
The electromagnetic wire uses pure oxygen-free copper wire with high conductivity. The winding adopts a new integrated package technology of cylindrical, double-cake and new spiral structures, making the product structure more compact. , the main insulation can be effectively guaranteed, and the first and last layers are strengthened to improve the insulation performance. The outer surface of the winding is wrapped with high-strength compression tape, which improves the mechanical strength of the winding and greatly improves the product's impact resistance and short-circuit resistance.
>Body
The insulating pads of the body are supported by high-strength laminated wood and laminated cardboard, so that the support area at the end of the winding reaches above, further improving the product's short-circuit resistance and improving Product operational reliability. The connection between the body and the box cover adopts a rigid buffer structure, which overcomes the phenomenon of the body hanging in the air and the top cover. The insulation materials are all wrapped with high-strength and high-density cable paper, and their allowable compressive stress is.
>Fuel tank
The fuel tank uses heat dissipation oil pipes (double-row and three-row oil pipes use insert fins or stepped fin radiators, which increase the heat dissipation capacity under the same tank wall area. The calculation can also be based on user requirements. Install a chip radiator or use a corrugated oil tank, and a strong oil air-cooled or strong oil water-cooled radiator. The surface treatment of the oil tank is made of three-proof paint (anti-salt spray, anti-humidity and heat, and anti-mold). This paint has strong adhesion to the primer. , has good decorative properties, the film has good oil resistance, corrosion resistance, gloss retention, and color retention, and has good leveling and hiding power. The structure is simplified and the appearance is beautiful. The oil tank adopts an anti-leakage design process to prevent oil tank leakage. Leakage.
