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)應具有可靠的電氣連接并接地(只對金屬橋架)。

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

　　2、當允許利用橋架系統(tǒng)構成接地干線回路時應符合下列要求。橋架端部之間連接電阻應不大于0.00033歐姆，接地孔應絕緣涂層。在1KV及以下中性點直接接地系統(tǒng)中，受電設備的接地與系統(tǒng)中性線接地相連。裝有處動切斷供電裝軒時，橋架的級長方向金屬橫截面積應不小于規(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、沿橋架全長另敷設接地干線時，每段(包括非直線段)橋架應少有一點與接地干線可靠連接。

　　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、對于振動場所，在接地部位的連接處應裝置彈簧圈。

　　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題，我們公司的產(chǎn)品質(zhì)量值得信賴，我們是您值得信賴的朋友。你們的滿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.
