The invention relates to the technical field of transformer substations, and specifically relates to an arrangement form of power distribution device HGIS equipment. The power distribution device HGIS equipment comprises a 1M side circuit breaker, a 1M middle circuit breaker, a 2M middle circuit breaker, a 2M side circuit breaker and a lightning arrester voltage transformer. The power distribution device HGIS equipment is in a double-layer or three-layer line incoming and outgoing form, and comprises a 1M busbar air sleeve, a 1M side line outgoing air sleeve, a middle line outgoing air sleeve, a 2M side line outgoing air sleeve and a 2M busbar air sleeve. The equipment has the advantages that the floor space when a power distribution device is arranged can be reduced, the floor space can be saved by 50% compared with a conventional manner, and after altitude correction, the equipment is applicable for high altitude localities as well; three-round line incoming and outgoing, same-side three-layer line outgoing and three-round line incoming and outgoing can be realized, under the requirement of double-side double-layer line outgoing, line incoming and outgoing are easier, and the connection is clearer; the using amount of equipment foundation concrete is reduced, the cost of foundation treatment is reduced, the cost of framework steel is reduced, and the engineering economy is improved.
