Cleaning and maintenance

低壓配電柜每隔一段時(shí)間都需要進(jìn)行清潔，以確保電氣元件的正常運(yùn)行。在清潔時(shí)，應(yīng)先切斷電源，用軟刷或干凈的布擦拭配電柜的表面，特別是蓋板、門和插座等易受灰塵和臟物積累的地方。同時(shí)，還要檢查配電柜的通風(fēng)孔是否被堵塞，如果有堵塞，應(yīng)及時(shí)清理，以免影響散熱效果。

The low-voltage distribution cabinet needs to be cleaned at regular intervals to ensure the normal operation of electrical components. When cleaning, the power should be cut off first, and the surface of the distribution cabinet should be wiped with a soft brush or clean cloth, especially in areas prone to dust and dirt accumulation such as covers, doors, and sockets. At the same time, it is also necessary to check whether the ventilation holes of the distribution cabinet are blocked. If there are blockages, they should be cleaned in a timely manner to avoid affecting the heat dissipation effect.

定期檢查

Regular inspection

為了保證低壓配電柜的正常運(yùn)行，定期檢查是必不可少的。可以選擇每半年或一年進(jìn)行一次檢查。檢查包括以下幾個(gè)方面：

Electrical components are the core part of low-voltage distribution cabinets and require frequent maintenance and upkeep. The specific methods for maintaining electrical components include:

清潔電氣元件表面的灰塵和臟物，確保其正常工作。

Clean the dust and dirt on the surface of electrical components to ensure their normal operation.

定期檢查電氣元件的工作狀態(tài)，如觸點(diǎn)是否干凈，接觸是否良好等。如有異常，應(yīng)及時(shí)更換或修理。

Regularly check the working status of electrical components, such as whether the contacts are clean and in good contact. If there are any abnormalities, they should be replaced or repaired in a timely manner.

定期檢查電氣元件的絕緣狀態(tài)，如有損壞或老化的情況，應(yīng)及時(shí)更換。

Regularly check the insulation status of electrical components, and replace them in a timely manner if there is any damage or aging.

防止電弧和漏電

Prevent arcing and leakage

電弧和漏電是低壓配電柜可能出現(xiàn)的隱患，需要采取相應(yīng)的預(yù)防措施。具體做法如下：

Arc and leakage are potential safety hazards that may occur in low-voltage distribution cabinets, and corresponding preventive measures need to be taken. The specific approach is as follows:

定期檢查配電柜的絕緣狀態(tài)，確保無漏電現(xiàn)象。如有問題，應(yīng)及時(shí)修復(fù)。

Regularly check the insulation status of the distribution cabinet to ensure that there is no leakage. If there are any problems, they should be repaired in a timely manner.

安裝并定期維護(hù)漏電保護(hù)器，及時(shí)發(fā)現(xiàn)漏電并切斷電源，確保人身。

Install and regularly maintain leakage protectors, promptly detect leakage and cut off power to ensure personal safety.

配電柜內(nèi)部的高壓設(shè)備應(yīng)安裝防弧罩，以防止電弧產(chǎn)生，確保工作的性。

The high-voltage equipment inside the distribution cabinet should be equipped with arc shields to prevent arc generation and ensure work safety.

定期校驗(yàn)和測(cè)試

Regular verification and testing

低壓配電柜的準(zhǔn)確性和可靠性需要定期校驗(yàn)和測(cè)試。可以選擇每年或兩年進(jìn)行一次校驗(yàn)和測(cè)試。包括以下幾項(xiàng)：

The accuracy and reliability of low-voltage distribution cabinets require regular verification and testing. You can choose to perform calibration and testing annually or biennially. Including the following items:
