母線(xiàn)槽的極限溫升值是指，母線(xiàn)槽通過(guò)額定電流滿(mǎn)負(fù)荷運(yùn)行時(shí)，穩(wěn)定下來(lái)的高溫度減去環(huán)境溫度得到的溫升值，通常用K來(lái)表示。下面濟(jì)南電纜橋架廠家為您講解更多相關(guān)事項(xiàng)：

The maximum temperature rise of a busbar duct refers to the temperature rise obtained by subtracting the ambient temperature from the stabilized high temperature when the busbar duct is operating at full load with rated current, usually expressed in K. Now, the manufacturer of cable tray in Jinan will explain more relevant matters to you:

母線(xiàn)設(shè)計(jì)時(shí)都會(huì)做溫升極限實(shí)驗(yàn)，溫升限制著母線(xiàn)的載流能力，溫升高會(huì)使得母線(xiàn)的壽命減短、電能損耗提高、電壓下降，同時(shí)也影響周?chē)h(huán)境溫度，加速周?chē)O(shè)備絕緣材料的老化，甚引起事故。

During the design of busbars, temperature rise limit experiments are conducted, which limit the current carrying capacity of the busbars. Temperature rise can shorten the lifespan of the busbars, increase electrical energy loss, decrease voltage, and also affect the ambient temperature, accelerate the aging of insulation materials for surrounding equipment, and even cause safety accidents.

在我國(guó)火災(zāi)事故中，屬電氣引起的火災(zāi)事故超出整個(gè)火災(zāi)事故的60%。而由電氣引起火災(zāi)事故的肇事者包括：電纜、電線(xiàn)、高低壓成套設(shè)備、變壓器、母線(xiàn)槽、電器元件等，大部分是由于長(zhǎng)期溫升高發(fā)熱，導(dǎo)致絕緣材料老化發(fā)生短路而引起的火災(zāi)事故。

In China, electrical fire accidents account for more than 60% of all fire accidents. The perpetrators of electrical fire accidents include cables, wires, complete sets of high and low voltage equipment, transformers, bus ducts, electrical components, etc. Most of them are caused by long-term temperature rise and heating, which leads to insulation material aging and short circuits, resulting in fire accidents.

極限溫升值可以說(shuō)是母線(xiàn)槽關(guān)鍵的技術(shù)參數(shù)，也是體現(xiàn)母線(xiàn)槽整體性能的一個(gè)重要指標(biāo)。用戶(hù)從母線(xiàn)槽的溫升還可以了解到以下幾個(gè)問(wèn)題：

The maximum temperature rise can be said to be a key safety technical parameter of the bus duct, and it is also an important indicator reflecting the overall performance of the bus duct. Users can also understand the following issues from the temperature rise of the bus duct:

①銅排的純度：含銅量直接與導(dǎo)體的電阻率相關(guān)，同樣的導(dǎo)體規(guī)格電阻率越大，溫升自然偏高。

① The purity of copper bars: The copper content is directly related to the electrical resistivity of the conductor. The higher the electrical resistivity of the same conductor specification, the higher the temperature rise naturally.

②導(dǎo)體的截面積：同樣的結(jié)構(gòu)和技術(shù)、同樣含銅量的導(dǎo)體截面積小，溫升自然偏高。

② The cross-sectional area of conductors: Conductors with the same structure and technology and the same copper content have a small cross-sectional area, resulting in a naturally high temperature rise.

③母線(xiàn)槽的散熱性能：絕緣材料及外殼結(jié)構(gòu)散熱不好，溫升自然偏高。

③ The heat dissipation performance of the bus duct: The insulation material and shell structure have poor heat dissipation, resulting in a naturally high temperature rise.

④連接頭結(jié)構(gòu)的好壞：連接頭接觸不好，溫升也會(huì)偏高。

④ The quality of the connector structure: Poor contact of the connector results in a higher temperature rise.

這下你明白線(xiàn)槽的極限溫升值指的內(nèi)容點(diǎn)是什么了吧，當(dāng)然在對(duì)該產(chǎn)品使用過(guò)程中，也要多注意一些事項(xiàng)，防止問(wèn)題的產(chǎn)生，更多事項(xiàng)就來(lái)我們網(wǎng)站http://m.ymmgjx.net咨詢(xún)了解吧！
