[0002] Smart grid-connected box-type substations are usually used to receive the output of new energy equipment such as wind turbines and photovoltaic power generation components, and boost the voltage to transmit it to the grid connection point. By installing multiple devices in independent boxes, the box-type substation structure is relatively compact, and it can be applied to urban construction while ensuring the reliability of power supply.
[0003] In the related art, the external structure of a box-type substation is mainly composed of three parts: the base, the shell, and the top cover. The base is generally made of channel steel, angle steel, flat steel, steel plate, etc., welded or bolted together to form; in order to meet the needs of ventilation, heat dissipation and inlet and outlet lines, strip holes and appropriately sized circular holes are opened at the corresponding positions. Among them, the top cover is an inverted V-shaped structure similar to the roof, which serves as a drainage and diversion structure and also as the top protection structure of the box-type substation. Most of the top covers are integrated structures with poor thermal insulation effect, and it is not convenient to replace the damaged parts in daily life, so there is still room for improvement.

[0033] Reference Figure 2 and Figure 3 In the present embodiment, the top plate assembly 3 comprises two inclined plates 32 and a connecting member 31 located between the two inclined plates 32.
