怎样看变压器是R 型还是C型
R型变压器是以外形结构名命的,他的截面像字母R,所以叫R型变压器
R-type transformer is named for its shape and structure. Its cross section is like the letter R, so it is called R-type transformer.
C型变压器是以外形结构名命的,他的截面像字母C 硅钢铁芯是方型 所以叫C型变压器
C-type transformer is named for its shape and structure. Its cross-section is square like the letter C silicon steel core, so it is called C-type transformer.
R型变压器是干式变压器产品中的一枝新秀。其铁芯系采用宽窄不一的优质取向冷轧硅钢带卷制成腰圆形,而且截面呈圆形,不用切割即可绕制。因此,由此制造的变压器无噪声、漏磁小、空载电流小、铁损低、效率高;并且由于线圈是圆柱形,每圈的铜线长度短,所以,内阻小,铜耗低,温升低,过载波动小,爆发力比环形变压器还好;另外,初、次级线圈采用阻燃PBT工程塑料制成的骨架分别绕制,从而抗电强度高,阻燃性好。
R-type transformer is a newcomer in dry-type transformer products. Its core is made of high quality oriented cold rolled silicon steel strip coil with different width, and its cross section is round, so it can be wound without cutting. Therefore, the transformer manufactured by this method has no noise, low magnetic leakage, low no-load current, low iron loss and high efficiency; moreover, because the coil is cylindrical and the copper wire length of each coil is short, the internal resistance is small, the copper consumption is low, the temperature rise is low, the over-carrier motion is small, and the explosive force is better than that of the ring transformer; moreover, the primary and secondary coils are made of flame-retardant PBT engineering plastics, respectively, so as to resist fire. It has high electric strength and good flame retardancy.
C形变压器也是铁芯变压器用冷轧硅钢带作铁芯,磁漏小,体积小,呈芯式结构(线圈包裹铁芯)。C 型铁心的制造过程是:冷轧硅钢带卷绕成形后,经热处理、漫渍等工艺制成封闭铁心,然后把封闭铁心切开.形成两个C 型铁心,将线包套入后,再把一对C 型铁心拼在起,并紧固捆扎在一起而构成变压器。 C 型铁心的气隙可以做得很小,还具有体积小、重量轻、材料利用率高等优点。
C-transformer is also a core transformer, which uses cold-rolled silicon steel strip as core. It has small magnetic leakage, small volume and core structure (coil wrapped core). The manufacturing process of C-type core is: after winding and forming of cold-rolled silicon steel strip, the closed core is made by heat treatment, diffusing and other processes, and then the closed core is cut open to form two C-type cores. After the wire is wrapped in, a C-type core is assembled and fastened together to form a transformer. The air gap of C core can be made very small, and it has the advantages of small size, light weight and high material utilization rate.
