　　When the busbar is installed vertically between floors, the single line length of busbar should not be greater than 3.6M. The floor with a single floor over 3.6M should be made for more than two sections, and the intermediate support should be installed between the floors. The connection point of the busbar slot should not be carried out at the floor of the floor, and there should be no sewage and sundries entering the busbar when the busbar slot is installed through the floor.

　　母線槽插接饋電孔應(yīng)設(shè)在可靠及安裝維修方便位置。插接箱安裝后，箱底高度不應(yīng)低于0.9M母線槽垂直安裝時(shí)，應(yīng)將彈簧支架安裝于母線槽上，再將母線槽及彈簧支架固定于槽鋼固定架上，鎖緊支架的彈簧螺母；待安裝4~5層后，由上向下逐層松開螺母，使母線槽重量自然承載于支架彈簧上。

　　The feed hole in the busbar slot should be located in the safe and reliable position of the installation and maintenance. The connection box is installed, the height should not be lower than the 0.9M busbar vertical installation, should be installed on the busbar on the spring bracket, then the busbar and spring bracket is fixed on the fixed channel frame, spring nut locking bracket; to install the 4~5 layer after layer by layer from top to bottom, loosen the nuts, the bus weight bearing on the natural groove on the spring bracket.

　　母線槽的過(guò)渡連接母線槽始端與配電柜接線端連接，應(yīng)采用鍍錫硬銅排過(guò)渡連接母線槽始端與變壓器、發(fā)電機(jī)組等震動(dòng)較大的設(shè)備連接時(shí)，應(yīng)采用銅編軟連接。銅母排與鋁導(dǎo)體連接時(shí)，應(yīng)采用銅鋁過(guò)渡排或夾裝銅鋁過(guò)渡片。

　　The transitional busbar busbar connection end and switchboard terminal connection, should connect busbar end connected with transformers, generators and other equipment with larger shock transition hard copper tin, copper series should adopt flexible connection. Copper bar and aluminum conductor connection, the copper aluminum transition row or clamping piece of copper aluminum transition.

　　母線槽運(yùn)行中，應(yīng)不間斷查看整條系統(tǒng)的四周是否存在滲漏、噴水、潛在的潮氣源。是否存在對(duì)系統(tǒng)構(gòu)成威脅的重物，以及對(duì)母線槽系統(tǒng)溫升構(gòu)成影響的熱源。檢查有無(wú)異物進(jìn)入母線槽內(nèi)部。

　　In the operation of the busbar slot, it should be uninterrupted to see if there is leakage, water spray and potential tidal source around the whole system. Whether there is a heavy object that poses a threat to the system, as well as the heat source that affects the temperature rise of the busbar system. Check whether there is a foreign body into the busbar slot.

　　檢查母線槽系統(tǒng)零部件有無(wú)缺損、銹蝕現(xiàn)象，支架彈簧是否有合適的彈力，發(fā)現(xiàn)問(wèn)題后立即更換。母線槽長(zhǎng)期運(yùn)行時(shí)每年定期檢測(cè)一次接頭溫升，接頭溫升應(yīng)按照GB7251標(biāo)準(zhǔn)不超過(guò)70K為合格（環(huán)境溫度為40℃）。

　　Check whether the parts of the busbar slot system have defects and rust, whether the support spring has the appropriate elastic force, and replace it immediately after the problem is found. The joint temperature rises regularly every year when the busbar slot is run. The temperature rise of the joint should be qualified in accordance with the GB7251 standard not more than 70K (the ambient temperature is 40).
