In the process of using the bridge, the grounding methods are different according to the different installation occasions. Do you know what kind of grounding methods are used? Next, we will sort out the relevant content for you.

橋架可能存在的安裝場合以及如何接地的情況有以下三種：

There are three possible installation situations and grounding methods for the bridge:

1、當允許利用橋架系統構成接地干線回路時，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中，受電設備的接地與系統中性線接地相連。

1. When the bridge system is allowed to form the grounding trunk circuit, the connection resistance between the ends of the bridge should not be greater than 0.00033 ohm, and the insulation coating should be removed from the grounding hole. In the 1kV and below neutral point direct grounding system, the grounding of the receiving equipment is connected with the neutral line of the system.

2、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定值。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。

2. When installing the dynamic cut-off power supply installation, the metal cross-sectional area in the direction of the bridge length shall not be less than the specified value. When another grounding main line is laid along the whole length of the bridge, at least one point of each section (including non-linear section) of the bridge shall be reliably connected with the grounding main line.

橋架安裝在不同場合如何接地

How to ground the bridge in different occasions

3、對于振動場所，橋架不同的安裝場合的接地要點說明：在接地部位的連接處應裝置彈簧圈。

3. For vibration places, the grounding points of different installation occasions of bridge: spring coil should 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有不少于兩處的連接。接地作業完成后需要檢查驗收。

The connecting plate can be used as the jumper wire between the cable trays to connect the trays as a whole. Galvanized spring washer is added on the two connecting bolts at both ends of the connecting plate. The bridge is bridged with soft copper wire, and then the bridge is connected with the grounding wire to form an electrical path. There shall be no less than two connections between the whole bridge and the grounding main line. After the completion of grounding operation, inspection and acceptance are required.
