American pre-installed box-type substation

Transportation, installation and maintenance Transportation The factory substation should be filled with 25#(or 45#) transformer oil as indicated by the oil level gauge in the tank. During transportation and loading and unloading, it shall not be inverted or turned over, shall not impact the parts, and shall not be strongly shaken Special attention should be paid to the lifting hook in the lifting hook of the fuel tank, and it should be lifted slowly to avoid damage to the paint on the surface of the substation by the wire rope, and even cause the center of gravity of the whole substation to shift, tilt, and fall. Install When the substation is installed on site, pay attention to the protection of the paint on the surface of the cabinet, do not allow the handle of the barometer, oil level meter, the thermometer, plug-in fuse and insulation sleeve element to bump, crack, etc., and the screws are not loose. Clean the dust and dirt outside the substation, inside the cabinet door and on the surface of the insulation sleeve. Check whether the name plate data and product certificate of the substation are consistent with the order, and check whether documents and spare parts are missing according to the packing list. The civil diagram of the inlet and outlet of the substation cable is shown in Figure 6. Maintenance The factory products have been strictly adjusted assembly, do not need to be disassembled during installation, so as not to affect the performance, maintenance is limited to the following situations: Sample analysis of transformer oil once a year; It is found that the oil level should be supplemented in time, and the brand of oi l is the same as that in the box: After the fuse is blown, the cause should be identified, and the specifications and models should be the same as the original specifications and models when replacing the melt core.
