R-type transformer winding machine
The cross section of an R-type transformer is like the letter R, so it is called an R-type transformer. The application of R-type transformers in high-power electrical appliances can reduce inrush current. R-type transformers are one of the dry-type transformers. The iron core is made of continuous high-quality oriented cold-rolled silicon steel strip from thin to thick, and then from thick to thin. The final cross-section is close to a circle, and the shape is an uncut closed rectangle, and then passes through a special R-shaped transformer The winding machine winds the coarse secondary on its PBT skeleton. Therefore, the transformer thus manufactured has no noise, low magnetic leakage, low no-load current, low iron loss, and high efficiency; and because the coil is cylindrical, the length of the coil copper wire wound by the R-type transformer winding machine is short, so , Low internal resistance, low copper consumption, low temperature rise, low over-carrier motion, and better explosive force than toroidal transformers; in addition, the primary and secondary coils are separately wound with flame-retardant PBT engineering plastic skeletons, thus high electrical strength , Good flame retardancy.
However, the manufacturing process is more complicated. The second is the winding of the coil. Because it is wound in a closed iron core, the PBT is composed of two parts, and then the R-type transformer winding machine drives the PBT skeleton to wind, and the winding accuracy is affected. A certain influence, one is the shape of its iron core, because its expanded shape is a spinning cone, so its mold and material utilization are relatively low.
With the development of R-type transformer winding machines, the reduction of manufacturing costs, and the improvement of quality stability, R-type transformers are being favored by more and more electronics industries with their novel and unique structure and excellent electromagnetic performance. Especially suitable for medical equipment, display equipment, audio equipment, office equipment.
R-type transformers can be used as power transformers or isolation transformers for all electrical appliances. It has the characteristics of high efficiency, small size and light weight. The material used for the R-shaped iron core is a high-grade cold-rolled oriented silicon steel sheet. After the iron core is wound by a winding machine, it is annealed to rearrange the molecular structure of the silicon steel sheet. R-type transformer is small in size and light in weight. The R-type transformer is wound with a non-cutting iron core and uses high-grade silicon steel sheets with high orientation, so it is small in size. Lightweight (30% smaller, 40% lighter, and 40% thinner than EI transformers). R-type transformer has high efficiency. Because the iron core is not cut, the iron loss is small, and the use of high-quality materials and compact structure minimizes the distance between the iron core and the windings wound by the R-type transformer winding machine, so the efficiency can reach more than 90% . R-type transformer has low magnetic leakage. The iron core of the R-type transformer has no magnetic gap and the winding is balanced, so the magnetic leakage is small. No need to design any anti-magnetic leakage measures. The R-type transformer generates little heat without noise. Since the R-type transformer is wound with a non-cutting iron core, it is made of high-grade silicon steel sheet with a uniform circular section. With the continuous coils wound by the R-type transformer winding machine, the resistance loss and heat generation are very low, and because there is no cutting, the magnetostrictive stress is easily absorbed, thus ensuring the application of noise-free. The excitation current of the R-type transformer is small. The R-type transformer is designed reasonably, so it has the characteristics of low iron loss, low heat generation, small excitation current and low energy consumption. R type transformer has high safety factor. Due to its unique design, the primary and secondary skeletons are separated, and the insulation performance is excellent. The separated skeletons made of flame-retardant materials can meet the standards of any country.
Suzhou REPOSAL Electronic Mechanical Equipment Co., Ltd. is a technology enterprise specializing in R&D and production of winding equipment. For many years, it has insisted on maintaining innovation and researching and developing products with independent intellectual property rights.
For quite a long time, my country's winding machine manufacturing industry generally has the problems of low technology, small scale, free and scattered production, and insufficient technological innovation of most enterprises. Compared with related industries abroad, my country currently has fewer types of winding machines and supporting equipment. The control technology used is relatively backward, and its accuracy and performance are not as good as those of their European and American counterparts. Moreover, the product has low production capacity and poor stability.
In the face of technical gaps, Suzhou REPOSAL made a detailed market research and took the entire series of precision winding machines and Roche coil winding machines as breakthrough points.It valued cooperation with user companies and not only carefully understood the existing process requirements of customers. And through the company's accumulated technical database for many years, on the premise of no or little increase in costs, it actively provides new ideas and new solutions for customer process upgrades.In a specific single implementation case, this approach has undoubtedly aggravated us The execution cost of the company has reduced the company's profits, but this idea has been implemented and verified for a long time.In fact, our customers have tapped the potential of the coil winding process through our winding machine equipment and become our long-term cooperative customers. We have also accumulated more technical data for our research and development direction and solutions through proactive improvement of individual cases, so as to achieve continuous innovation.
Transformer winding machine:
Similar to transformers, current transformers also work according to the principle of electromagnetic induction. The transformer transforms voltage and the current transformer transforms current. The current transformer is connected to the winding of the measured current (the number of turns is N1), called the primary winding (or primary winding, primary winding); the winding connected to the measuring instrument (the number of turns is N2) is called the secondary winding (or secondary side) Winding, secondary winding).
This ring current transformer winding machine is generally used to wind small size current transformers. The characteristics of small size current transformers are generally wire diameter of enameled wire between 0.11-0.19mm, and the number of turns is large.
It requires accurate turns and fast winding speed.
REPOSAL this machine is fast and stable, and the speed reaches 1400RPM. Because it is stable, it can realize the operation of multiple ring current transformer winding machines by one person.
Precision Flexible Roche Coil Winding Machine is a special equipment for winding precision flexible Roche coils. With the actual project as the background, Xiepu successfully developed a precision flexible Rogowski coil winding machine by decomposing the flexible Rogowski coil winding process.
The precision flexible Roche coil winding machine does not belong to the ranks of general numerical control equipment, but a special non-standard equipment. For this type of equipment, it is mainly reflected in a special purpose. Since the special purpose means that the market demand is not large, it is indispensable. For equipment manufacturers, the development of such special equipment is not favored, and cost control is very difficult.
In addition, the current domestic manufacturers of flexible Roche coils have limited demand for equipment. At the same time, if you want to control the pitch accuracy and alignment, the equipment research and development costs are relatively high, and the market risk is large. At the same time, for equipment users, their corresponding The supporting equipment and instruments are a large investment.
