Single-phase isolation control transformer JBK series

产品简介

Overview

JBK3 series machine tool control transformers are suitable for circuits with AC 50-60Hz and input voltage not exceeding 660V. This series of transformers are other products that control transformers and are manufactured with imported materials and advanced technology. They have reliable operation, low energy consumption, small size, safe wiring, and wide applicability to the point of manufacture. JBK5 series machine tool control transformers are the latest transformer series introduced by our company in Germany in the 1990s. On the basis of domestic JBK3 series machine tool control transformers, after many years of further absorption of similar foreign products, and foreign advanced methods are selected to scale the structure of terminal blocks and connect the terminals Combined with the skeleton, the protection level is increased to IP2LX to prevent accidental contact with the circuit. Using domestic IT cold-pressed terminal blocks, the wiring method can improve the wiring density. The connection between the silicon steel sheet and the silicon steel sheet of the transformer, and the connection between the silicon steel sheet and the bottom plate are all welded by argon arc welding, forming a whole, which is quick and clear. Especially the bottom plate is formed at one time, the installation size is more accurate than the JBK3 series, and the high-quality anti-corrosion alloy material is used, which greatly improves the reliability of the grounding performance and comprehensively improves the product quality. The product conforms to VDE0550, IEC204-1, IEC439, JB/T9446-1999, GB5226 and other relevant international and national standards. Interchangeable with foreign products.
