Equipment introduction The complete set of equipment is designed and manufactured according to the mechatronics structure. Among them, the intermediate frequency power supply is a set of 6- pulse thyristor KGPS200KW/8KHZ intermediate frequency power supply, the load is a set of GTR series induction heating furnace, and the equipment is equipped with a set of reactive power compensation capacitor bank. The device is designed with manual and automatic power adjustment knobs, among which automatic is the temperature closed-loop control mode. The external control console is controlled by PLC (Siemens) and touch screen. The touch screen can easily input heating parameters, such as copper wire specifications, heating speed, annealing temperature, etc. After the parameters are input, the closed loop control system of the intermediate frequency power supply temperature will automatically adjust the output power, thereby Meet production needs. When a certain link in the production fails, the intermediate frequency power supply can be insulated according to the set temperature to avoid overburning the copper wire. The equipment is placed according to user requirements, facing the equipment from left to right, the operating table is placed toward the main equipment, which is conducive to the operator to observe the production situation and facilitate the adjustment of parameters.

Safety protection The equipment has complete safety protection measures, such as water shortage protection, phase lack protection, over current protection, over voltage protection, under voltage protection, high water temperature protection, etc., and there is an audible and visual alarm device for faults. The equipment is configured according to 200KW , leaving enough power margin to ensure continuous and stable production of the equipment for 24 hours. All exposed conductors are installed in the electric control box with a lock, and there are eye-catching safety reminders, so no electrical safety accidents will occur. Each interlocking device can avoid damage to equipment or copper wires due to manual misoperation.

Struktur peralatan Set lengkap saka peralatan kalebu area udakara 2000 * 1500mm, kanthi dhuwur tengah 1000mm. Sumber daya digabungake karo awak tungku pemanasan, lan bolt ekspansi digunakake kanggo ndandani. Peralatan kasebut dirancang kanthi konsol eksternal, sing bisa diatur kanthi karsa miturut kahanan situs, sing trep kanggo operasi. Instalasi piranti kasebut gampang lan cepet. Pangguna mung perlu kanggo nyambungake welingan banyu lan pipo stopkontak karo welingan banyu lan pipo stopkontak peralatan (siji muncung kanggo saben welingan banyu lan stopkontak), lan nyambungake telung phase papat-kabel kanggo mburi ndhuwur peralatan.

2.3 Teknologi pilihan peralatan lengkap

Set lengkap peralatan kalebu sistem kontrol sumber daya frekuensi penengah, sistem pangukuran suhu serat optik inframerah adoh, sistem kontrol loop tertutup suhu, bank kapasitor kompensasi daya reaktif, awak tungku annealing pemanasan induksi, lsp.

Sistem kontrol daya frekuensi menengah:

2.3.1 Sumber daya frekuensi penengah yaiku piranti frekuensi variabel thyristor, voltase input yaiku 380V, 50Hz, lan daya output yaiku 200KW. Daya bisa diatur kanthi manual utawa kanthi otomatis miturut suhu sing disetel. Frekuensi output yaiku 8KHz (pelacakan frekuensi otomatis). Werna kabinet ditemtokake miturut syarat pangguna, ukuran garis 2000 × 1500 × 1300mm, lan dhuwur tengah 1000mm.

2.3.2 jinis Cartridge gabungan rak silikon

Bagian rectifier lan inverter saka thyristor nggunakake pigura silikon gabungan modular paling anyar kanthi aplikasi paten. Cara instalasi iki ndadekake disassembly lan perakitan thyristor luwih trep lan ilmiah. Nalika ngganti thyristor, mung loosen. Bolt tightening bisa ngganti sembarang unsur thyristor ing Déwan. Kajaba iku, cara instalasi iki kanthi nyuda volume komponen SCR, sing ora mung nambah ruang operasi ing kabinet listrik, nanging uga nyuda kerugian garis.

2.3.3 Reaktor smoothing DC kapasitas gedhe

Reaktor smoothing penting banget kanggo pasokan listrik sing padhet, duwe rong fungsi. Pisanan, nggawe arus output saka rectifier lancar lan stabil. Kapindho, nalika thyristor inverter short-circuited, tingkat wutah saka short-circuit saiki lan ukuran maksimum short-circuit saiki diwatesi. Yen desain parameter saka reaktor Filter iku khayal, materi inti ora apik utawa proses Manufaktur ora cukup apik, iku bakal duwe impact gedhe ing linuwih digunakake saka sumber daya frekuensi penengah.

2.3.4 SCR kapasitas gedhe

Supaya kanggo mesthekake linuwih saka operasi peralatan, loro rectifier lan inverter thyristor nggunakake Xiangfan basis stasiun gedhe-kapasitas KP lan KK silikon kanggo mesthekake operasi stabil saka peralatan.

2.3.5 Gunakake seri lan baris rugi podo kanggo nyuda mundhut saka garis transmisi

Kanggo nyuda kerugian ing garis transmisi frekuensi penengah, kapasitor kompensasi inverter disambungake kanthi bentuk dobel voltase seri lan paralel.

2.3.6 Paramèter sirkuit utama lan basis pilihan komponen

Parameter sing dirating saka sirkuit utama sumber daya frekuensi penengah ditampilake ing tabel ing ngisor iki:

The inductor is composed of a furnace shell, an induction coil, a stainless steel water collector and a furnace lining. The induction coil is combined with the parameters of the annealed copper alloy tube to optimize the design with special computer software and make it in combination with actual experience. It can ensure the best electromagnetic coupling efficiency under the same capacity. Induction coils with 99.99% of T2 rectangular copper wire made, the induction coil outer insulating electrostatic spray process the epoxy resin insulating layer of high strength, pressure-resistant insulating layer is greater than 5000V .

The inner layer of the induction coil is made of white corundum lining, and the outside of the lining and between the coils are fixed with refractory cement (American Union Mine), which can play a role in insulation and heat preservation. At the same time, the strength of the white corundum lining is further increased, effectively avoiding copper wire damage to the lining.

Kabeh banyu mlebu lan metu saka sensor diklumpukake dadi rong traps banyu stainless steel, sing disambungake menyang pipa inlet lan outlet banyu utama. Penagih banyu stainless steel iku ayu lan praktis, kang bisa èfèktif ngindhari pengaruh boros panas saka coil induksi amarga karat pipa banyu lan blockage saka saluran banyu.
