  • 220V轉380V變壓器N相對接地有電壓~急

    因為我們設備需要用到380V的電壓

    將原本三相三線220V轉為三相四線380V的電

    關於N相這點不是很懂

    一般來說我的認知是N相對接地線量0V

    ABC對N都是220V

    可是這次使用的變壓器發生了這樣的情形

    ABC對N也是220V

    但N對接地還有90V的電壓

    有試量ABC對地 分別為280V.280V.127V

    詢問過變壓器的廠商,

    他們回覆將N相和接地線接在一起

    就可以消除掉那90V的電壓

    但是覺得這樣接很怪 這樣N相的功能也變成接地

    因為不確定這樣做正不正確

    因此設備也不敢通電

    想請教一下這樣子是正常的嗎?

    會發生這種狀況是變壓器的問題還是其他地方的問題...?

    因為對變壓器這種不是很懂,還請各位大大賜教

  • 機車發動時 把鑰匙熄火拔掉還是一直點火

    發動機車的時候

    都會先按煞車再點火

    通常都是一點火 發動後就放掉

    點火的聲音就沒了

    今天我點火的時候

    跟往常一樣 先按煞車再點火

    放掉之後

    點火的聲音沒停!

    以前曾經遇過這種情況(也是一樣剛下完雨的天氣)

    我熄火就會停了

    可是今天熄火連鑰匙都拔出來了

    那個聲音還是一直在點

    我不曉得是哪裡出問題了

    趕快騎到附近的機車行修

    老闆看到之後,說這個要趕快處理,否則會燒掉

    於是我就傻傻的看著他拆了我的電池

    (牽到那邊去,熄火的時候過沒多久就不點了,應該是電池沒電)

    拆了坐墊,看到他從管線中抽出了一條線

    那條線上面有兩個金屬頭,粗粗的黑色的一條

    他說是這條線壞了,什麼之類的

    然後又換了一顆電池,他說 先試試看能不能發

    結果發動了 也沒有那個情況發生。

    於是我問老闆這樣要多少?

    老闆回說:那條線750,電池900,總共1650

    我聽到我傻眼了,竟然要那麼貴

    我覺得我電池的地方被坑了,其實根本不用換吧

    問題一:像上述那種情況是哪邊有問題呢?

    問題二:如果真的是那條線的問題,真的有那麼貴嗎?

    附帶一問:電池多久需要換一次?(我的電池2年半)

  • 租賃問題-房客將房屋讓給同事住,但未繳租金,該如何解決

    租賃問題

     

     假設我是房東,而我將房子以租期一年租給了A,但A住了6個月左右。因為房租一個月未繳,於是聯絡了A,A才說他已不住在那,現在房子是他的同事B在住,聯絡B之後B繳了一個月的房租。

     我想說:既然現在房子是B在住,那應該要與他重新訂契約。但之後B沒訂契約的意思(多次約時間簽約,卻沒出現),就當作現在租的是A。

     但現在此房租已2個月未繳,當初的保證金是以兩個月房租來算。現在兩個月到了。

    問題

    1.我想將房子要回去,我可以這麼做嗎(租期未滿一年)?該怎麼做?

    2.如果B一直佔著,這種行為觸法嗎?觸犯哪些法?

    3.同上,我可以用哪些方式驅離?

    (目前想到的方式:斷水斷電,換鎖。但我可以這麼做嗎?)

    現在情況:

    A連絡不上(聽A講是說他在國外)。

    B一直說 "過兩天"(過兩天之後還是說"過兩天")。

    請問有人遇過相同的情況嗎?

    能不能給我一些解決的方法?

    謝謝大家^^

    我寫了一篇關於iPod 的文章,為了做報告><

    請各位高手幫忙看看有沒有文法的錯誤。

    謝謝^^

    III-1 iPod

    What is iPod? This could listen to MP3, play videos with tiny size and large storage. The iPod has four models, iPod shuffle, iPod nano, iPod classic, and iPod touch. All of them could use iTune which bring you more colorful for your life.

    The iPod shuffle looks like a common MP3, but it offers more convenient features. For example, it has the 2GB flash drive that could store more than 300 songs, skip-free playback design which could let you listen to music without lag anywhere, the battery indicator, and the shuffle model. And then, iPod shuffle’s battery could play 12 hours when fully charged. But the most convenient is its tiny and light, iPod is only 10.5mm depth and 15.6g weight that you could enjoy music anywhere.

    The iPod nano is a small iPod with a big idea: Video. With the firmness and wafer-thin 6.5mm, it should play up to 5 hours of video or 24 hours of audio. The iPod has the great characteristic of each products-Click Wheel-that could make you easy to use the iPod. Use the Click Wheel, you could browse the album cover while you listen to music, adjust the volume, or flip your photos by slip your finger.

  • Some grammar check, please?

    I wrote two paragraphs about iPod.

    I need to check the grammar.

    Maybe has a lot errors, thank you.

    ********************

    The iPod classic is the iPod nano evolutional version. The iPod classic owns more storage, playback time, and display screen than nano, that could store 40,000 songs with 160GB, play 40 hours music and own 2.5-inch with 163 pixels per inch. If you stored more than 10,000 songs, what did you find the song which you want to listen? Apple knew this question. So, the iPod classic has a new feature-search-let the iPod user could easy to find what you need.

    While Apple succeeds in putting Muti-Touch in screen, the iPod touch is born. The iPod touch not only owns all iPod features, but also has many new and unique services. The new service─Wireless─which could let you connect to the Internet, view the YouTube, browse maps from Google maps, read and write e-mail anywhere. Especially, you can view your e-mail which brings PDF, Word, or Excel anywhere with the iPod touch.
