With the power of the widespread use of electronic devices, power grids in the harmonic pollution is becoming increasingly serious. Now widely used harmonic approach is to minimize harmonic or harmonic filters. Filtering equipment not only the traditional high-cost equipment investment, but also a waste can be used by the harmonic energy. This paper presents a harmonic use of a motor drag the methods and devices, the device can be harmful to the power grid and the electricity sector is being filtered out of the harmonic energy use, used to drive DC motor. Key words: Harmonic Harmonic Harmonic suppression against the passive filter fundamental harmonic drag degaussing circuit希望对你有帮助

Along with the electric power electronic installation's widespread use, in electrical network's overtone pollution condition is day by day serious. At present widely uses the overtone processing method is reduces the overtone or the filtration overtone as far as possible. The traditional filter equipment not only facility cost high invests in a big way, moreover wasted in vain has been possible to perform the use the overtone energy. The present paper proposed that one kind carries on the electrical machinery dragging using the overtone the method and the equipment, this equipment can the electrical network harmful, and present is filtered by the electric power department the overtone energy uses, uses in actuating the direct current machine. 谐波 The overtone谐波的危害 the overtone harm谐波抑制 harmonic suppression 无源滤波器 The passive filter, 基波消磁电路the fundamental wave degaussing electric circuit 谐波拖动the overtone drives

摘要:一种方法数字中继距离的建议是合适的超高压复合架空线和地下电缆电路应用。建议继电器整合了电路的并联电容在除了一系列的电阻和电感。通过模拟电路的保护作为了一系列的RLC区段中继算法,更大的接触点的准确性是可以实现的。不像传统的距离继电器从这个意义上的故障回路阻抗和比较,这对一个达到一点价值,建议继电器采用了定向元素的基础上,计算达到点的电压和电流值。结果介绍的基础上,综合500千伏的应用研究包括两架空线路路段和两个有线电视节。比较与传统的数字距离继电器算法显示即超越几乎是消除在建议的继电器。仿真结果已核实一执行继电器基于现代数字信号处理硬件。

KBSG2 - T mining flame-proof dry type transformer, KBSGZY2 - T FLP transformer substation of explosive shell adopts alien bellows tube structure, small volume, light weight, high mechanical strength, and no dust, shell top not water, beautiful appearance. Its core is the permeability of high quality cold-rolled orientation of silicon steel, iron section by section, semi-circular structures iron long narrow width, reduced the large core, it reduces the overall height to width of core transformer, three pillars of length, thus effectively shorten greatly narrowed the volume of transformer. Core structure is adopted, and the whole punching, TaiJieShi crisscross juncture, iron yoke with low magnetic steel plates and Italy, high-strength fiberglass binding H200 with fastening structure, effectively reduce the noise and no-load loss, no-load current core structure, thus strengthening the reliability and sophistication.KBSG2 - T mining flame-proof dry type transformer, KBSGZY2 - T FLP transformer substation of electromagnetic line drawn high-quality non-oxygenic copper wire to reduce the resistivity, insulation wrap select high-quality insulating materials - dupont Nomex? Insulation, special vacuum pressure impregnating VPI by UL certification solvent-free class H, high-temperature baking varnish, so as to ensure the electrical insulation intensity and coil mechanical strength, greatly improves the performance of the transformer.Features--------------------------------------------------------Shell take small intercept overall shape structure, corrugated cylinder without seam between ripple, corrugated cylinder cover adopted advanced surface structure, improve the mechanical strength, thermal properties of product improvement. Products with compact structure, small volume, light weight, top not dust, etc, and its water is superior performance index of similar products.Use conditions-------------------------------------------------------- The altitude does not exceed 1000mEnvironmental temperature than 40 ° c + +Air relative humidity is not more than 95% (+ 25 ° c),In methane gas mixture and coal-dust explosion and the pit, and can also be used to dust severe explosion place,No severe turbulence, vertical vibration and the gradient of not more than 15 ° environment,Without enough to corrode metal and destruction of the gas and steam insulation,Without dripping place,The power supply voltage waveform is symmetrical, approximate sine waves.
