絕緣和水分。
Insulation and moisture.
通常,這相對(duì)常見,通常在直接埋地或激勵(lì)的電纜接頭處產(chǎn)生。例如:電纜橋架接頭不合格,接頭在濕氣態(tài)條件下進(jìn)行,接頭是入口或混合到水蒸氣中,在電場(chǎng)效應(yīng)下構(gòu)成水樹枝,電纜的絕緣強(qiáng)度逐漸傷害。
Usually, this is relatively common and usually occurs at cable joints directly buried or excited. For example, if the cable tray joint is unqualified, the joint is carried out under the wet gas condition. The joint is imported or mixed into the water vapor, forming a water tree under the effect of the electric field, and the insulation strength of the cable is gradually damaged.
化學(xué)原料的腐蝕。
Corrosion of chemical raw materials.
電纜橋架直接埋在酸基效應(yīng)區(qū)域。它通常構(gòu)成電纜的裝甲,鉛或外護(hù)套,這導(dǎo)致由于長(zhǎng)時(shí)間導(dǎo)致化學(xué)腐蝕或電解腐蝕,導(dǎo)致保護(hù)層失效,絕緣,并且它也將導(dǎo)致電纜缺點(diǎn)。
The cable tray is directly buried in the acid base effect area. It usually constitutes the armor, lead or outer sheath of the cable, which leads to the failure of the protective layer and insulation due to long-term chemical or electrolytic corrosion, and it will also lead to cable defects.
長(zhǎng)時(shí)間超負(fù)荷運(yùn)載。
Long time overload.
由于電流的熱效應(yīng),負(fù)載電流肯定會(huì)導(dǎo)致導(dǎo)體的發(fā)熱,同時(shí)充電,以及鋼制甲的渦流損失,以及絕緣介質(zhì)損失也可以是添加,然后溫度增加。當(dāng)過(guò)載運(yùn)行很長(zhǎng)時(shí)間時(shí),過(guò)高的溫度加速了絕緣的年齡,使絕緣體被打破。特別是在炎熱的夏天,電纜的溫度升高常常導(dǎo)致電纜絕緣的初級(jí)擊穿單位,所以在夏季,電纜的缺點(diǎn)很多。
Due to the thermal effect of the current, the load current will certainly lead to the heating of the conductor, the charging at the same time, the eddy current loss of the steel armour, and the loss of the insulating medium can also be added, and then the temperature increases. When overloaded for a long time, the excessive temperature accelerates the age of insulation and breaks the insulator. Especially in hot summer, the temperature rise of the cable often leads to the primary breakdown unit of the cable insulation. Therefore, in summer, the cable has many disadvantages.

電纜連接器的缺點(diǎn)。
Disadvantages of cable connectors.
橋接接頭是電纜線的更薄,這通常由由人員直接疏忽(消費(fèi))引起的電纜接頭的缺點(diǎn)產(chǎn)生。在制造電纜連接的過(guò)程中,施工人員可能導(dǎo)致電纜頭減少,然后觸發(fā)沒(méi)有足夠網(wǎng)絡(luò)的電纜頭的解釋。
The bridging joint is the thinner of the cable, which is usually caused by the shortcomings of the cable joint caused by the direct negligence (consumption) of personnel. In the process of manufacturing cable connections, the construction personnel may cause the cable head to be reduced, and then trigger the explanation of cable head without sufficient network.
環(huán)境和溫度元素。
Environmental and temperature elements.
山東電纜橋架和電纜周圍的外部環(huán)境和熱源也將構(gòu)成電纜溫度,絕緣擊穿和嚴(yán)重的組成爆炸。
Shandong cable tray and the external environment and heat source around the cable will also constitute cable temperature, insulation breakdown and serious composition explosion.
外力危險(xiǎn)。
Danger of external force.
目前的電纜缺點(diǎn)主要由機(jī)械危害引起。例如,請(qǐng)參閱:當(dāng)使用電纜時(shí),請(qǐng)勿標(biāo)準(zhǔn)化構(gòu)造,并簡(jiǎn)單地構(gòu)成機(jī)械危險(xiǎn);在直接埋葬電纜中易于參與土木工程。在某些情況下,電纜的危害并不嚴(yán)重。也許幾個(gè)月或幾年可能有一個(gè)缺點(diǎn)的有害部分的缺點(diǎn),電纜損壞較重可能產(chǎn)生短路短路缺點(diǎn),直接影響電纜橋架。
Current cable disadvantages are mainly caused by mechanical hazards. For example, please refer to: when using cables, do not standardize the structure, and simply constitute a mechanical hazard; It is easy to participate in civil engineering in direct buried cables. In some cases, the cable hazard is not serious. There may be a defect in the harmful part of a defect in a few months or years. If the cable is seriously damaged, it may cause short circuit, which will directly affect the cable tray.
