Medium frequency furnace filter reactor

? ? ? ?Medium frequency furnaceFilter reactorIt is a reactor professionally designed and manufactured for intermediate frequency furnace power supply filtering and smoothing. There are different models according to the different power, frequency and current of the intermediate frequency power supply.Medium frequency furnaceFilter reactor. It is mostly used in the DC circuit after the rectification of the intermediate frequency power supply to suppress the ripples of the DC line. The DC of the thyristor DC line is closer to the ideal DC. here,Haishan electric furnaceThe editor will introduce this setMedium frequency furnaceFilter reactor。

one,Medium frequency furnaceFilter reactorPerformance parameters:

1. Can be used in 400V and 660V systems.

2. Rated insulation level 3kV/min.

? ? ? ? 3、Medium frequency furnaceFilter reactorThe temperature rise limit of each part: the iron core does not exceed 85K, and the coil temperature rise does not exceed 95K.

? ? ? ? 4、Medium frequency furnaceFilter reactorThe noise is not greater than 50dB.

? ? ? ? 5、Medium frequency furnaceFilter reactorThe difference between the reactance values ??of any two phases shall not be greater than ±2%.

? ? ? ? 6、Medium frequency furnaceFilter reactorTemperature resistance grade H (180℃) or above.

two,Medium frequency furnaceFilter reactoreffect

? ? ? ? 1、Medium frequency furnaceFilter reactorMake the output current of the rectifier smooth and stable.

2. WhenMedium frequency furnaceWhen the inverter thyristor is short-circuited, the growth rate of the short-circuit current and the maximum short-circuit current are limited.

three,Medium frequency furnaceFilter reactors material

? ? ? ? Medium frequency furnaceFilter reactorThe silicon steel sheets are made of Z10 cold-rolled high-permeability products, and the copper tubes are T2 extruded copper tubes, wrapped with high-strength mica tape, and H-class insulated. in order to reduceMedium frequency furnaceFilter reactorTo reduce the working noise, the silicon steel sheets adopt a special fastening process, and there are special buffering and sound-absorbing materials between the silicon steel sheets and the air gap.

Four,Medium frequency furnaceFilter reactorProduction process requirements

? ? ? ?1、Medium frequency furnaceFilter reactorLp implements filtering on I, Ip - → pulsation is greatly reduced - + gentle and continuous - → constant current source Ip (relatively instantaneous) - while Vd (both ends of the inverter bridge after Ld) has large pulsation → Ld mechanical vibration is weak.

? ? ? 2、Medium frequency furnaceFilter reactorLd-Cfl forms an F-shaped filter to filter Vd. Vd-→pulsation is greatly reduced-→>smooth and continuous→constant voltage source Vd-→while Ip has large pulsation-+L mechanical vibration is large.

? ? ? ?3、Medium frequency furnaceFilter reactorThe Ld requires high mechanical strength and low vibration. Secondly, the inductance is smaller than the reactor Ld of the parallel inverter power supply.

? ? ? ?4、Medium frequency furnaceFilter reactorLd is often made into a multi-layer hollow inductor with a larger diameter, and measures to enhance mechanical strength are taken, such as tight bundling, pouring epoxy resin, and secure installation.

five,Medium frequency furnaceFilter reactorTroubleshooting:

? ? ? ? 1、Medium frequency furnaceFilter reactorIf the coil insulation is not good, you can check whether the insulation materials of all reactor coils meet the requirements, and soak the reactor coils in insulating paint.

? ? ? ?2、Medium frequency furnaceFilter reactorProblems occurred during the assembly process, which caused cracks in the insulation layer of the reactor, which could also cause fire and burnout.

? ? ? 3、Medium frequency furnaceFilter reactorThe shell of the intermediate frequency power supply cabinet is not well insulated.

? ? ? 4、Medium frequency furnaceFilter reactorThe water pressure of the cooling water in the coil does not meet the requirements, causing the reactor coil temperature to be too high. Or the reactor has been used for too long, and there is too much scale on the inner wall of the reactor coil of the Haishan electric furnace, resulting in poor heat dissipation of the reactor coil. 5.Medium frequency furnaceFilter reactorThe intermediate frequency voltage is too high; the use environment of the intermediate frequency power supply and reactor is not good, such as being too humid.
