110kv city transformer substation arrangement system

Abstract

The invention discloses a 110kv city transformer substation arrangement system. The 110kv city transformer substation arrangement system comprises a transformer substation, the transformer substation comprises a plurality of substations, all-insulation pouring buses or cables are laid among the substations on the ground or under the ground, wherein the cables comprise optical fiber intelligent monitoring power cables, and the optical fiber intelligent monitoring power cables are used for monitoring the temperature of the cables; and the multiple substations comprise 110kv power distribution devices, if the 110kv power distribution devices among the multiple substations adopt a line transformer group wiring mode, the 110kv power distribution devices in different substations are not electrically connected, and if the 110kv power distribution devices among the multiple substations adopt a single-bus segmented wiring mode, the 110kv power distribution devices in different substations are electrically connected through 110kV cross-linked polyethylene insulated power cables. According to the110kv city transformer substation arrangement system, one substation is divided into the multiple substations, and each substation has an independent power supply capability, so that the power supply efficiency is improved, and the occupation of land resources is reduced.

Description

technical field [0001] The invention relates to the technical field of substation design, in particular to a 110kv urban substation layout system. Background technique [0002] With the tighter land use indicators, higher environmental impact assessment requirements, and improper rejection of substations by residents, site selection for new substations has become more and more difficult. Some substations have not been able to determine the site after many years, resulting in the development of electricity production and the local economy. There are many uncertain negative effects, and for the built-up area, if a new substation needs to be built due to the increase of load density and other reasons, the difficulty of site selection will increase significantly. If the surrounding terrain caused by the long size of the fence is considered Due to the difference in landform, side slopes / retaining walls, drainage ditches, etc. need to be set up outside the station, and the actual ...
