Product synopsis:
Our company produces the ZSS series rectifier transformer ZS, as the rectification device power transformer, its function is to provide the ac power rectifier, rectifier for dc and ac conversion, and thus for the dc power supply. Mainly used in metallurgy, chemical, locomotive traction and transmission, etc. Energy-saving, low loss, low noise, impact resistance and resistance to short-circuit ability. Overload ability strong, compact structure, small volume, power supply reliability, etc.
Product features:
(1) electrical performance stability: the products combine with load characteristics and grid voltage fluctuation, atmospheric overvoltage conditions, according to the load conditions, rectifying transformer for determination of reasonable and reliable insulation level and insulation model, fully guarantee the electrical performance reliable products and stable. Product environmental safety coefficient 1.67 p.
(2) dynamic stability degree is high: product winding has high mechanical strength and a comparatively strong ability to meet sudden extreme load environment. In the design, manufacture process to eliminate the transformer is better from or magnetic leakage can cause abnormal transportation of dynamic instability source. The product has high dynamic stability. With high resistance and power transformer capacity than the impedance higher than 30%.
(3) good thermal stability: advanced product design, and strictly control the product fever parts and the most hot temperature, and the temperature rise of margins, soak in, if need in a coil add axial oil way, according to coil load loss value selection cooling way and reasonable distribution of oil flow, achieves the best cooling effect, main temperature indexes at least 5 ℃ lower than the gb. Coil, lead by copper wires, current density selection is low.
(4) overload ability: the product has strong load capacity and overvoltage ability, can in the rated load cases long-term safety operation, can be in for 110% of full load overvoltage case long-term security operation (environment temperature ℃); 40 Transformer and motor connecting terminal can withstand the 1.5 times rated current and lasted 5S. Product design, manufacture fully consider load characteristics, temperature, excellent insulating performance from the attachment choice and so on various aspects meet overload requirements.
(5) performance index is superior: no-load current design, manufacturing is lower S9 series with capacity of transformer, according to gb/e. fully users with the use of the economy and reliability.
(6) energy-economizing effect is obvious, low noise (< 65dB).
(7) it has simple structure, beautiful shape; Tank take leakage design process, we can eliminate tank leakage.
The product structure
(1) core: using 30Q130 silicon steel, high magnetic with into advanced 3 ~ 6 levels of step - lap core stacking stepping multistage laminated way, to reduce the no-load loss, idle current and noise.
(2) winding: electromagnetic line used high conductivity anaerobic copper wire, winding adopts cylinder type, double cakes type and new spiral structure of the whole suit the new technique, products more compact structure, the main insulation can get effective guarantee to strengthen up layer, and improve the insulation. Winding outside surface coil with high strength, improve the tightening of the winding mechanical strength, make the product impact resistant capability and resistance to short-circuit capacity is greatly increased.
(3) implement body: implement body insulation spacers are high strength of the laminated wood and laminated board support, make winding ends support area reached 95% above, further improve the product short-circuit capacity, improve product resistance of operation reliability. Implement body and the connection box cover by the inflexible, overcome with cushioning sheet.the body "impending" and "top" phenomenon. Insulation materials are using high strength, high density cable paper, the permissible pressure around for 45Mpa.
(4) : oil tank tank by cooling tubing (double row and three rows of tubing adopts plug way), or use tablet chip radiator in the same step under the box wall area increased heat capacity; Also can install chip radiator according to the requirements of users, and corrugated tank or by strong oil cooling or strong oil cooled radiator. Surface treatment: transformer tank shell paint USES "anti-corrosion paint" (anti salt fog, prevent tepid, prevent mould), topcoats and primer adhesion, adornment sex is good, film oil resistance, corrosion resistance, the outstanding gloss and color retention is good, has the good softness and covering power.
Applicable rectifier circuit:
Commonly used for single-phase half wave rectifier circuit single-phase and three-phase whole wave, half wave and three-phase wave (Y or train) bridge type, three-phase winding type (Zo shape), six phase Y shape (midpoint wiring), six phase furcated (and twists shape), six phase Y shape parallel bridge type (with balance reactor), six phase train Y shape series bridge type and twelve phase four twists and turns with balance reactor, six image in Y shape or train form, six phase (12, 24 phase) with double inverse star balance reactor, or many sets of parallel bridge type, double reflexive star circuit. Dc current can reach 25KA, dc voltage from dozens of volts to several hundred volts, valve side with often adopted from inverse parallel method goes.
