Lead terminal identification number from the winding power transformer has two windings common, namely a primary and a secondary winding s terminal line signals, so there are four terminals. Some of the power transformer to prevent hum and other disturbances, the early, often between the secondary winding plus a shield, which shield the ground. Therefore, the power transformer terminals is at least four. 1. Identify common power transformer from the shape of the E-shaped core has two, and C. E-shaped core transformer was shell structure (core wrapped coil), using D41, D42 high quality silicon steel core, widely used. C-shaped cold-rolled silicon steel core transformer as the core, magnetic leakage, small size, was the core structure (coil wrapped core). 2. From the winding leads to the number of terminals to recognize the power transformer has two windings longest common s cable, namely a primary and a secondary winding, so there are four terminals. Some of the power transformer to prevent hum and other disturbances, the early, often between the secondary winding plus a shield, which shield the ground. Therefore, the power transformer terminals is at least four. 3. Identify the way from the E-shaped silicon steel laminations silicon power transformer is inserted pay * s terminal line production, between E and I slice slice gap is not empty, the entire core match exactly. Audio input, output transformer piece left between E and I slice a certain air gap, which is the most intuitive way to distinguish power and audio transformers. As for the C-shaped transformers, power transformers are generally. Terminals in the global technology revolution speed of the situation, the maturity of the connector products are widely used in various industries in the field of the national economy. As China becomes the world's factory, the rapid development of manufacturing products for the increasingly terminals The larger market space, but to date, the domestic terminals can also be said that the market dominated by foreigners, German and other European countries occupy a larger market share. With the improvement of technology areas, terminals own structure and development of technology has also been one generation of innovation, our terminals has also ushered in a revolution in the industry to catch up with similar foreign products in the development process. Today our terminals market is expanding, technological advances, talent is increasing, along with efforts to increase state support for private businesses to invest and grow, local terminal enterprises will usher in their golden age. However, we believe that this age want to maintain long-term, it would make the technology to the next level, that is, continue to go beyond technology. The only way to ensure that local products abroad than in the products have a greater advantage. s terminal line sequence, s cable, electronic products factory Song Chong-wook from Dongguan Shijie Xu Song Chong electronic products factory provided.
