Pre-installed Box Type Substation Installation Requirements
The pre-installed box type substation should be placed at a relatively high place, not in low-lying areas, to prevent rainwater from entering the box and affecting equipment operation. When pouring concrete platforms, gaps should be left on the high and low voltage sides to facilitate the laying of cables in and out. When excavating the foundation, if encountering the ground formed by the accumulation of garbage or corrosive soil, it must be excavated to solid soil, then backfilled with good soil quality and compacted, and then filled with three layers of soil or gravel to ensure the stability of the foundation.
The grounding and neutral connection of the pre-installed box type substation share a common grounding network. The grounding grid generally adopts the method of driving grounding piles at the four corners of the foundation, and then connecting them as a whole. There must be two reliable connections between the pre-installed box type substation and the grounding grid. After operation, the grounding connection should be checked regularly to ensure it is not loose or corroded. Regularly measure the grounding resistance, not exceeding 4 Ω.
The pre-installed box type substation mainly adopts natural air circulation cooling. Therefore, debris should not be piled up around it, especially the transformer room door. Louver ventilation holes should also be regularly removed to ensure that the equipment does not exceed the maximum allowable temperature.After the low-voltage circuit breaker trips, the cause should be identified before power can be transmitted to prevent the accident from expanding.
The high-voltage chamber of the pre-installed box type substation should be equipped with zinc oxide lightning arresters, and the installation method should be convenient for testing and replacement.
Equipment such as ring network switches, transformers, lightning arresters, etc. in the high-voltage room should be regularly inspected and maintained, defects should be discovered and dealt with in a timely manner, and insulation preventive tests should be conducted regularly. If it is discontinued for more than 3 months and is put into operation again, a full project preventive test should be conducted.
To replace a high-voltage fuse without breaking capacity, the transformer must be powered off, and the mechanical interlock must be properly released during operation, and an insulated operating rod must be used.
All incoming and outgoing cable holes of the pre-installed box type substation should be sealed to prevent small animals from entering and causing accidents.
Must have a warning sign of "high voltage danger" and a nameplate number for electrical equipment.

The ambient air temperature does not exceed 40℃, and the lower ambient air temperature is -25℃;
The altitude does not exceed 1000 meters, if you use specially ordered transformers and low-voltage components, it can reach an altitude of 3000 meters;
Places where the vertical inclination does not exceed 5°, no severe vibration and no impact;
The air humidity is not more than 90% (25℃);
No conductive dust, no explosion hazard, no gas place that corrodes metal and electrical components;
The outdoor wind speed does not exceed 35m/s.
