EUROELETTRO變壓器,EUROELETTRO變頻器
品牌簡介
意大利EUROELETTRO生產(chǎn)變壓器、變頻器,產(chǎn)品廣泛用于電力行業(yè)。
變壓器的特性參數(shù)
1工作頻率
變壓器鐵芯損耗與頻率關(guān)系很大,故應(yīng)根據(jù)使用頻率來設(shè)計(jì)和使用,這種頻率稱工作頻率。
1 operating frequency
The core loss of transformer is closely related to frequency, so it should be designed and used according to the use frequency, which is called working frequency.
2額定功率
在規(guī)定的頻率和電壓下,變壓器能長期工作,而不超過規(guī)定溫升的輸出功率。
2 rated power
Under the specified frequency and voltage, the transformer can work for a long time without exceeding the output power of the specified temperature rise.
3額定電壓
指在變壓器的線圈上所允許施加的電壓,工作時(shí)不得大于規(guī)定值。
3 rated voltage
It refers to the allowable voltage applied on the coil of transformer, which shall not be greater than the specified value during operation.
4電壓比
指變壓器初級(jí)電壓和次級(jí)電壓的比值,有空載電壓比和負(fù)載電壓比的區(qū)別。
4 voltage ratio
It refers to the ratio of primary voltage to secondary voltage of transformer, which is different from no-load voltage ratio and load voltage ratio.
5空載電流
變壓器次級(jí)開路時(shí),初級(jí)仍有一定的電流,這部分電流稱為空載電流??蛰d電流由磁化電流(產(chǎn)生磁通)和鐵損電流(由鐵芯損耗引起)組成。對(duì)于50Hz電源變壓器而言,空載電流基本上等于磁化電流。
5 no load current
Transformer secondary open circuit, the primary still has a certain current, this part of the current is called no-load current. The no-load current consists of magnetizing current (producing magnetic flux) and iron loss current (caused by core loss). For a 50 Hz power transformer, the no-load current is basically equal to the magnetizing current.
