Box-type substation structure with high protection level

Abstract

The invention discloses a box-type substation structure with high protection level. The four sides of a box opening on a door frame are bent outwards to form flanged edges, and the splicing of the flanged edges at the corners of the box opening is smoothly transited through circular arcs. Sealing rubber is clamped onto the flanged edges. After a left door and a right door are closed, the inner wall surfaces of the left door and the right door abut against the sealing rubber. A groove sealing plate is arranged at the right end of the left door, and the upper and lower ends of the groove sealing plate are bent to form U-shaped clamping platforms. The left end of the right door is bent inward to form a rib. The rib is provided with clamping slots matched with the clamping platforms at the upper and lower ends. After the left door and the right door are closed, the rib extends into the groove cavity of the groove sealing plate, and the clamping platforms are clamped to the clamping slots. The sealing rubber on the upper side of the door frame and the sealing rubber on the lower side of the door frame are correspondingly clamped into the groove cavities of the U-shaped clamping platforms. The box-type substation structure is reasonable in design, has a good protection effect, and can meet the requirement of a high-protection-level box-type substation used in harsh environments.

Description

[0001] Technical field: [0002] The invention relates to a box-type transformer structure with high protection level, which belongs to the field of box-type transformer manufacturing. [0003] Background technique: [0004] Photovoltaic power generation, as an emerging industry of new energy power generation, is experiencing vigorous development in recent years. Photovoltaic grid-connected power stations are generally composed of multiple independent units. The power transmission path is: solar modules, inverters, combiner boxes, and then to box-type transformers. The voltage is raised to AC 35kV, and then the generated power is sent to the The step-up substation is then sent to the national grid as a whole. It can be seen that the box-type transformer is a core equipment in the entire photovoltaic power station, and the reliability of the equipment is directly related to the safe operation of the power grid system. [0005] The construction of photovoltaic power plants requ...

Problems solved by technology

[0006] Conventional box-type transformers are used as power terminal equipment, generally close to the load center, and the climate environment is generally good, so the overall protection performance of the box-type transformer is also weak
