Line reactors for the inverter into the end of the series, a line drive into the reactor. Drive at work will have a greater harmonic order 5,7,11,13 times based, high harmonic content, if you do not put the line reactor, will greatly shorten the life of the inverter and other equipment harmonic interference is serious, it will cause some devices not functioning properly, the installation of line reactors will greatly reduce the harmonic content, improve the power factor, to ensure the safe operation of the inverter and other loads, ensure that other equipment from harmonic interference; installation of reactor outlet can passivate the inverter output voltage (switching frequency) of steepness, reducing turbulence and shocks in the inverter power components. And the line reactor in the closing moments load circuit can effectively suppress inrush current protection circuit of the inverter devices and other components from over-current shock. Second, the line reactor 1. The structural characteristics of the line for a three-phase reactors, are the core dry. 2. The core of high-quality low-loss import cold-rolled silicon steel sheet, the gap with epoxy glass cloth laminated board for the interval to ensure that the reactor gap does not change during operation. 3. Class H coil using enamelled copper wire flat, tightly packed and uniform appearance does not include an insulating layer, and there is an excellent aesthetic and better heat dissipation. 4. Line reactor coil and core assembly into one after pre-drying → vacuum impregnation → Hot baked curing this process, the use of H-grade varnish, so that the reactor coil and core firmly together not only greatly reduce the noise when running, but has a very high heat levels to ensure noise-free reactor can also run safely at high temperatures. 5. Line reactor core columns using non-magnetic material portion of the fastener to reduce eddy current heating phenomenon runtime. 6. exposed parts are taking anti-corrosion treatment, leads to terminals tinned brass terminals. 7. The line reactors and similar products, compared with a small size, light weight, beautiful appearance, etc., can be comparable with foreign brands. Deqing Shandong Electric Manufacturing Co., Ltd. is a professional electrical manufacturing enterprises in 1987 was officially designated as the national machinery industry sentinel enterprises, and issued a low-voltage electrical production license. The company is mainly engaged in the reactors, transformers, resistors, braking resistor such as product development, manufacturing, sales and service, with many years of electrical design, development and manufacturing experience. Has a skilled professional and technical personnel and senior management, with independent development, manufacturing applied to different areas of the ability of various types of electrical products. The first in the industry through the IS09001 international quality system certification, 2000 international quality system certification of products to meet international standards. www.sddqel.com/
