我厂配电所1250kVA、10/0.4kV 变压器低压侧 DW10—2500/3型自动空气开关的辅助触点接线胶木座,安装在二次回路熔丝接线铁盒前,电工检查和更换二次回路保险丝时,必须爬上距地面3m 高的开关,先将熔丝铁盒前的辅助接点胶木座拆除,再打开铁盒盖更换熔丝,更换后再复原.由于空气开关安装在距地面3m 高的墙上,并且变压器低压出线的大截面母排及空气开关出线母排均沿开关前面的支架敷设,开关断开后,开关进线侧铝母排仍带电(此时变压器不停运),电工检查和更换熔丝很不安全,
I plant distribution 1250kVA, 10 / 0.4kV low voltage side of the DW10-2500 / 3 automatic air switch auxiliary contact bakelite bakelite seat, installed in the second loop before the fuse fuse box, electrician check and replace the secondary circuit Fuse, you must climb the switch 3m high from the ground, first remove the auxiliary bakelite seat before the fuse box, and then open the iron lid to replace the fuse, replace and restore. Since the air switch installed in the ground 3m high Of the wall, and the transformer low voltage outlet of the large cross-section of the busbar and air switch outlet busbar are laid along the front of the switch bracket, the switch off, the switch into the line side of the aluminum bus is still charged (at this time the transformer does not stop shipping) Electrician check and replace the fuse is not safe,
