橋架安裝在不同場(chǎng)合如何接地

在我們使用橋架的過程中,根據(jù)其安裝的場(chǎng)合不同,其采用的接地方式也是不一樣的,那么您知道分別采用的什么樣的接地方法嗎?下面我們?yōu)槟硐嚓P(guān)內(nèi)容。
In the process of using the cable tray, the grounding methods are different according to the different installation occasions. Do you know what grounding methods are used? Now let's organize the relevant content for you.

In the process of using the cable tray, the grounding methods are different according to the different installation occasions. Do you know what grounding methods are used?
橋架可能存在的安裝場(chǎng)合以及如何接地的情況有以下三種:
There are three possible installation occasions and grounding methods for cable tray:
1、當(dāng)允許利用橋架系統(tǒng)構(gòu)成接地干線回路時(shí),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)中性線接地相連。
1. When the cable tray system is allowed to form the grounding trunk circuit, the connection resistance between cable tray ends shall not be greater than 0.00033 ohms, and the insulation coating shall be removed from the grounding hole. In the neutral point direct grounding system of 1KV and below, the grounding of the receiving equipment is connected with the system neutral line grounding.
2、裝有處動(dòng)切斷供電裝軒時(shí),橋架的級(jí)長方向金屬橫截面積應(yīng)不小于規(guī)定值。沿橋架全長另敷設(shè)接地干線時(shí),每段(包括非直線 段)橋架應(yīng)少有一點(diǎn)與接地干線可靠連接。
2. When equipped with automatic cut-off power supply device, the metal cross sectional area of the cable tray in the level direction shall not be less than the specified value. When the grounding main line is laid along the full length of the bridge, at least one point of each section (including the non straight line section) of the bridge shall be reliably connected with the grounding main line.

3、對(duì)于振動(dòng)場(chǎng)所,橋架不同的安裝場(chǎng)合的接地要點(diǎn)說明:在接地部位的連接處應(yīng)裝置彈簧圈。
3. Key grounding points for vibration places and different installation occasions of bridge: spring coil shall be installed at the connection of grounding parts.
電纜橋架之間可利用連接板作為跨接線,把橋架連成一體。在連接板兩端的兩只連接螺栓上加鍍鋅彈簧墊圈,橋架之間用軟銅線進(jìn)行跨接,再將橋架與接地線相連,形成電氣通路。橋架整體與接地干線應(yīng)有不少于兩處的連接。接地作業(yè)完成后需要檢查驗(yàn)收。
Connecting plates can be used as jumpers between cable trays to connect them into a whole. Galvanized spring washers are added to the two connecting bolts at both ends of the connecting plate. Soft copper wires are used for bridging between bridges, and then the bridge is connected with the grounding wire to form an electrical path. There shall be at least two connections between the whole bridge and the grounding trunk. Inspection and acceptance are required after the grounding operation is completed.
