帶插口的母線槽維護方便嗎?
First, the installation of the bus slot can be directly received from the transformer to low-voltage distribution cabinet, or from the low-voltage cabinet directly connected to the distribution system as the main line of distribution. The bus duct with a socket can conveniently draw out the power supply through the socket head box or the plug-in switch box. The utility model has the advantages of small volume, compact structure, large transmission current, convenient maintenance, etc..
1、空氣清潔，相對濕度在高為+40℃時不超過50%，在較低溫度時允許有較高的相對濕度;例如+20℃時為90%，但應考慮到由于溫度的變化，有可能會偶然地產生適度的凝露。
1, clean air, relative humidity was the highest in +40 degrees is less than 50%, allowing a higher relative humidity in the low temperature of 90% DEG C; for example +20, but should be taken into account due to temperature changes, may occasionally produce moderate.
2、母線槽保證在下列環境中長期正常工作:
2. The busbar ensures long term operation in the following environment:
3、周圍空氣溫度在-5～+40℃之間，并在24h內其平均溫度不高于+35℃;
3, the ambient air temperature is between 5 and +40 degrees centigrade, and the average temperature in 24h is not higher than +35 degrees centigrade;
2、.海拔高度不超過2000m;
2. Altitude is not more than 2000m;
二、槽式電纜橋架接地要點
Two, the grounding of groove type cable bridge
1、對于振動場所，在接地部位的連接處應裝置彈簧圈。
1. For vibration site, the spring shall be installed at the joint of the grounding part.
2、橋架系統應具有可靠的電氣連接并接地(只對金屬橋架)。
2 the bridge system shall have reliable electrical connections and earthing (only for metal bridge).
