                  極限溫升值可以說是母線槽關鍵的安全技術參數,也是體現母線槽整體性能的一個重要指標。用戶從母線槽的溫升還可以了解到以下幾個問題,下面山東電纜橋架廠家為您解說。
                  The limit temperature rise can be said to be the key safety technical parameter of the bus duct, and also an important indicator reflecting the overall performance of the bus duct. The user can also understand the following problems from the temperature rise of the bus duct, and the Shandong cable bridge manufacturer will explain for you.
                  母線槽的極限溫升值是指,母線槽通過額定電流滿負荷運行時,穩定下來的高溫度減去環境溫度得到的溫升值,通常用K來表示。母線設計時都會做溫升極限實驗,溫升限制著母線的載流能力,溫升高會使得母線的壽命減短、電能損耗提高、電壓下降,同時也影響周圍環境溫度,加速周圍設備絕緣材料的老化,甚至引起安全事故。
                  The limit temperature rise of the bus duct refers to the temperature rise obtained by subtracting the ambient temperature from the stabilized high temperature when the bus duct runs at full load through the rated current, usually expressed in K. The temperature rise limit test will be conducted during the design of the bus. The temperature rise limits the current carrying capacity of the bus. The temperature rise will shorten the life of the bus, increase the power loss, and reduce the voltage. At the same time, it will also affect the ambient temperature, accelerate the aging of the insulation materials of the surrounding equipment, and even cause safety accidents.
                  在火災事故中,屬電氣引起的火災事故超出整個火災事故的60%。而由電氣引起火災事故的肇事者包括:電纜、電線、高低壓成套設備、變壓器、母線槽、電器元件等,大部分是由于長期溫升高發熱,導致絕緣材料老化發生短路而引起的火災事故。
                  Among the fire accidents, the fire accidents caused by electricity account for more than 60% of the total fire accidents. The perpetrators of fire accidents caused by electricity include cables, wires, high and low voltage complete sets of equipment, transformers, bus ducts, electrical components, etc. Most of them are fire accidents caused by aging insulation materials and short circuit due to long-term temperature rise and heating.

                  ①銅排的純度:含銅量直接與導體的電阻率相關,同樣的導體規格電阻率越大,溫升自然偏高。
                  ① Purity of copper bar: the copper content is directly related to the resistivity of the conductor. The higher the resistivity of the same conductor specification, the higher the temperature rise.
                  ②導體的截面積:同樣的結構和技術、同樣含銅量的導體截面積小,溫升自然偏高。
                  ② Cross-sectional area of conductor: with the same structure and technology and the same copper content, the cross-section area of conductor is small, and the temperature rise is naturally high.
                  ③母線槽的散熱性能:絕緣材料及外殼結構散熱不好,溫升自然偏高。
                  ③ Heat dissipation performance of bus duct: insulation material and shell structure are poor in heat dissipation, and the temperature rise is naturally high.
                  ④連接頭結構的好壞:連接頭接觸不好,溫升也會偏高。
                  ④ The quality of the connector structure: if the connector contact is not good, the temperature rise will also be high.
                  母線槽在使用的時候,防水措施一定要好,因為當水進入到母線槽內部的時候,會使得母線槽的絕緣性能變差,長期這樣使用會導致母線槽短路,使得供電出現問題,這樣會影響工作。雖然母線槽本身有很好的防水措施,但是為了以防萬一在安裝的時候,也要有一定的防水的防護措施。
                  When the bus duct is used, the waterproof measures must be better, because when the water enters the bus duct, the insulation performance of the bus duct will become worse. Long-term use will lead to short circuit of the bus duct, causing power supply problems, which will affect the work. Although the bus duct itself has good waterproof measures, certain waterproof protection measures should be taken in case of installation.
                  當母線槽在樓層中穿越的時候,一定要找一個好的穿著點,這樣避免因為天氣不好樓層之間相互漏水影響母線槽的使用,如果母線槽在使用中出現故障還有可能會給用戶帶來一定的損傷,所以要注意不管母線槽在什么地方使用都要注意它的防水措施!更多相關內容就來我們網站http://www.pembertonchristian.com咨詢了解!
                  When the bus duct passes through the floor, it is necessary to find a good place to wear it, so as to prevent the use of the bus duct from being affected by water leakage between floors due to bad weather. If the bus duct breaks down in use, it may also cause some damage to the user, so it is necessary to pay attention to its waterproof measures no matter where the bus duct is used!
