Our company is a cable tray supply enterprises, grounding on the bridge, you know how much? The grounding problem today we are going to introduce to you is the cable tray, follow the pace of a small series together to see it, I hope to help you.

　　1、橋架系統(tǒng)應(yīng)具有可靠的電氣連接并接地(只對(duì)金屬橋架)。

　　1, the bridge system should have a reliable electrical connection and grounding (only on the metal bridge).

　　2、當(dāng)允許利用橋架系統(tǒng)構(gòu)成接地干線(xiàn)回路時(shí)應(yīng)符合下列要求。橋架端部之間連接電阻應(yīng)不大于0.00033歐姆，接地孔應(yīng)絕緣涂層。在1KV及以下中性點(diǎn)直接接地系統(tǒng)中，受電設(shè)備的接地與系統(tǒng)中性線(xiàn)接地相連。裝有處動(dòng)切斷供電裝軒時(shí)，橋架的級(jí)長(zhǎng)方向金屬橫截面積應(yīng)不小于規(guī)定值。

　　2, when allowed using the bridge system composed of grounding line circuits should meet the following requirements. The bridge between the end part of the connecting resistance should be less than 0.00033 ohm, grounding hole should remove the insulating coating. In the neutral grounding system of 1KV and below, the grounding of the receiving device is connected with the neutral grounding of the system. A dynamic assembly when the power supply is cut off, the prefect direction of metallic cross-sectional area should not be less than the specified value.

　　3、沿橋架全長(zhǎng)另敷設(shè)接地干線(xiàn)時(shí)，每段(包括非直線(xiàn)段)橋架應(yīng)少有一點(diǎn)與接地干線(xiàn)可靠連接。

　　3, the other along the bridge length of laying ground lines, each segment (including non straight segment) bridge shall have at least one point and the grounding line connection.

　　4、對(duì)于振動(dòng)場(chǎng)所，在接地部位的連接處應(yīng)裝置彈簧圈。

　　4, for the vibration place, in the grounding part of the connection should be equipped with coil.

　　以上就是小編給大家介紹的電纜橋架的接地問(wèn)題，我們公司的產(chǎn)品質(zhì)量值得信賴(lài)，我們是您值得信賴(lài)的朋友。你們的滿(mǎn)意就是我們不懈的追求。讓我們共同為明天的美好而努力吧。

　　These are small to the grounding cable bridge introduce problems, the quality of our products is worthy of trust, we are your most trusted friend. Your satisfaction is our unremitting pursuit. Let us work together for a better tomorrow.
