江蘇春晨電纜有限公司生產(chǎn)春晨 YCB扁電纜 卷筒扁電纜,壓標(biāo)準(zhǔn)合格率是衡量電能質(zhì)量的主要指標(biāo)之一??墒怯捎诜N種原因,高峰和低谷時期的用電量往往相差懸殊,造成配電變壓器輸出電壓偏低,設(shè)備不能用,而電壓的忽高忽低對各種用電設(shè)備的性能、生產(chǎn)效率和產(chǎn)品質(zhì)量都有不同程度的影響,因此,為了確保供電電壓的合格率,及時調(diào)節(jié)配電變壓器分接開關(guān)位置是解決問題的辦法之一。那么如何調(diào)變壓器的輸出電壓,變壓器電壓低怎么調(diào)高。
The qualified rate of voltage standard is one of the main indexes to measure the power quality. However, due to various reasons, the power consumption in peak and low periods is often quite different, resulting in the low output voltage of distribution transformer and the unavailability of equipment, and the fluctuation of voltage has different degrees of influence on the performance, production efficiency and product quality of various electrical equipment. Therefore, in order to ensure the qualified rate of power supply voltage, adjust the tap changer position of distribution transformer in time Is one of the solutions to the problem. Then how to adjust the output voltage of the transformer, how to adjust the low voltage of the transformer.

我們國家民用變壓器高壓側(cè)(一般為10kV)繞組標(biāo)準(zhǔn)設(shè)三檔分接開關(guān)供調(diào)壓;
Our country's civil transformer high voltage side (generally 10kV) winding standard sets three grade tap changer for voltage regulation;
三檔分接開關(guān)為:中間檔對應(yīng)電壓Ue,另二檔對應(yīng)電壓分別為+5%*Ue、-5%*Ue;
The third gear tap changer is: the middle gear corresponds to the voltage UE, and the second gear corresponds to the voltage ue of + 5% * UE and - 5% * UE respectively;
三檔的繞組匝數(shù)是變壓器出廠時固定的:設(shè)Ue檔時繞組匝數(shù)為Ne,+5%*Ue檔時繞組匝數(shù)為N1、-5%*Ue檔時繞組匝數(shù)為N2;低壓側(cè)繞組匝數(shù)N固定不可調(diào)。
The winding turns of the third gear are fixed when the transformer leaves the factory: when the UE gear is set, the winding turns are ne; when the + 5% * UE gear is set, the winding turns are N1; when the - 5% * UE gear is set, the winding turns are N2; the winding turns n of the low-voltage side are fixed and not adjustable.
匝數(shù)N1大于匝數(shù)N2,匝數(shù)Ne介于N1與N2間;
Turns N1 is greater than turns N2, and turns ne is between N1 and N2;
變壓器的變比為n=(Ne、N1、N2)/N,n=Ne/N為額定變比;低壓側(cè)電壓U2=高壓側(cè)U1/n;
The transformation ratio of the transformer is n = (NE, N1, N2) / N, n = Ne / N is the rated transformation ratio; the voltage U2 at the low voltage side is U1 / N at the high voltage side;
U1為系統(tǒng)電壓,我們無法改變;
U1 is the system voltage, which we cannot change;
若U2太低,由U2=U1/n知,我們只需降低n即可;春晨 YCB扁電纜 卷筒扁電纜
If U2 is too low, from U2 = U1 / N, we only need to reduce N;
請看看變壓器分接開關(guān)現(xiàn)在在哪檔,從n=(Ne、N1、N2)/N中選擇n稍小的那檔試試,依此類推。
Please see which gear the transformer tap changer is in now, choose the gear with smaller n from n = (NE, N1, N2) / N, and so on.
