Description

Lightning protection module layout structure of box-type substation Technical Field The application relates to the technical field of lightning protection of box-type substations, in particular to a lightning protection module layout structure of a box-type substation. Background As an integrated power device, a box-type substation is widely used in urban power grids, industrial parks and other places, however, because it is usually in an outdoor environment, it is vulnerable to lightning attacks. The high voltage and large current generated by lightning can invade the inside of the box-type transformer substation to damage electrical equipment such as a transformer, a switch cabinet and the like, so that power failure accidents are caused, normal power supply is influenced, and even safety accidents are caused. The existing lightning protection measures of the box-type transformer substation are mainly concentrated on traditional lightning protection devices such as an installation lightning rod and a lightning arrester, but the layout structure of the lightning protection devices has some defects, for example, the installation positions of the lightning arrester are dispersed, the effective integral protection is difficult to form, and the reasonable collaborative layout is lacking among lightning protection modules, so that the lightning protection effect is not ideal, and therefore, a novel box-type transformer substation lightning protection module layout structure is needed to improve the lightning protection effect and ensure the safe and stable operation of the box-type transformer substation. Disclosure of utility model Aiming at the defects of the prior art, the application provides a lightning protection module layout structure of a box-type transformer substation, solves the problems of unreasonable lightning protection module layout and poor lightning protection effect in the prior art, and improves the lightning protection capability of the box-type transformer substation. In order to achieve the purpose, the technical scheme is that the lightning protection module layout structure of the box-type substation comprises a box-type substation box body, wherein a top lightning protection module is arranged at the top of the box-type substation box body, a side wall of the box-type substation box body is provided with a side wall lightning protection module, an inner lightning protection module is arranged inside the box-type substation box body, the top lightning protection module comprises lightning rods installed at four corners of the top of the box-type substation box body, the lightning rods are connected with top grounding down conductors, the top grounding down conductors extend to the bottom of the box-type substation box body and are grounded, the side wall lightning protection module comprises a plurality of lightning arresters evenly distributed along the periphery of the side wall of the box-type substation box body, the lightning arresters are connected with side wall grounding down conductors, the lightning arresters are grounded through side wall grounding down conductors, the inner lightning protection module comprises a surge protector arranged above electrical equipment inside the box-type substation box body, the surge protector is grounded through the inner grounding down conductors, and the bottom of the box-type substation box body is provided with the grounding down conductors. Through above-mentioned scheme, because among the prior art lightning protection module overall arrangement is unreasonable, lightning protection effect is not good, through the lightning protection module at the top of box-type substation box, lateral wall and inside set up different functions, formed from outside to inside multilayer lightning protection system, can effectively intercept the lightning invasion of different directions and intensity, box-type substation's lightning protection ability has been improved greatly, top lightning protection module, lateral wall lightning protection module and inside lightning protection module's ground connection downlead are connected to same ground net jointly, guaranteed the quick release of lightning current, reduced the risk that electrical equipment was damaged. Further, the lightning rod is an early discharge type lightning rod, and the installation height of the lightning rod is higher than that of other equipment at the top of the box-type substation box body. Through above-mentioned scheme, adopt the lightning rod that discharges in advance and the installation height is higher than other equipment in box transformer substation box top, the lightning rod that discharges in advance can produce upstream guide earlier in ordinary lightning rod, catch the thunder and lightning guide more effectively, introduce the ground with the thunder and lightning in advance, thereby protect box transformer substation more effectively and avoid directly hitting th
