為防止外界電壓危害人身安全和對設備的損害，抑制電氣干擾，保證通信設備正常工作来源www.xbaixing.com。

電信設備接地的注意事項

1.當低壓配電系統採取tn制式供電，電信設備若要求嚴格限制工頻交流對其的干擾

2.若電信設備不易做到與站內各種金黃色屬構件絕緣時，應採用tn-s制式;

3.當對干擾要求不太嚴格時，可採用tn-c制式;

4.當電信設備的泄漏電流在10ma及以上時，應採用tn-s制式;

5.當採取it制式供電，電信設備的泄漏電流在10ma以上時，為了避免保護設備誤動作，可採取雙線圈變壓器供電fry。

6.電信設備的工作接地，一般要求單獨設置，與建築物內變壓器的工作接地共用一個接地裝置時，必須通過絕緣的專用接地線與接地裝置相連;

7.電信設備採用共同接地裝置時，其接地電阻應不大於1ω，用兩根截面積不小於25mm2的銅芯絕緣線穿管敷設到共同接地極上x~b~a~i~x~i~n~g~c~o~m。當採用基礎鋼筋作為共同接極時，連接處應有銅鐵過渡接頭来自www.xbaixing.com。

Precautions for grounding of telecommunication equipment

1. When the low-voltage power distribution system adopts the tn system power supply, if the telecommunication equipment requires strict restriction on the interference of the power frequency communication

2. If the telecommunication equipment is not easy to be insulated from the various golden components in the station, the tn-s system should be adopted;

3. When the interference requirements are not strict, the tn-c system can be adopted;

4. When the leakage current of telecommunication equipment is 10ma or more, the tn-s system should be adopted;

5. When the power supply of the standard system is used, when the leakage current of the telecommunication equipment is above 10ma, in order to avoid the malfunction of the protection device, the power supply of the double coil transformer can be adopted.

6. The working grounding of telecommunication equipment is generally required to be set separately. When sharing a grounding device with the working ground of the transformer in the building, it must be connected to the grounding device through a dedicated grounding wire for insulation;

7. When the telecommunication equipment adopts the common grounding device, its grounding resistance should be no more than 1ω, and it should be laid on the common grounding pole with two copper insulated wires with a cross-sectional area of not less than 25mm2. When the base steel bars are used as common joints, there should be copper-iron transition joints at the joints.
