Description

Technical Field

[0001] The utility model relates to the field of substations, and more specifically, to an integrated outdoor substation. Background Art

[0002] In an integrated outdoor substation, as an important component of power transmission, the stability and safety of cables are directly related to the operation efficiency and reliability of the entire power system; the protective substation proposed in the Chinese utility model patent application number: CN202321220970.3, includes a base, a transformer, a bracket and a protective device. The transformer is fixedly connected to the upper surface of the base, the bracket is fixedly connected to the upper surface of the base, a conductive cable is bolted to the upper surface of the bracket, a control cabinet is fixedly connected to the upper surface of the base, the control cabinet is electrically connected to the transformer, and the protective device is arranged at the connection between the bracket and the conductive cable. The protective device includes an outer mask, the outer mask is sleeved on the side surface of the bracket, an inner mask is sleeved on the side surface of the bracket, and a sealing strip is fixedly connected to the side surface of the outer mask. In this utility model, by setting the protective device, the protection of the cable connection part of the mobile substation is increased.

[0003] However, there are still some deficiencies in the existing substations during use that need to be improved. Traditional cable clamping devices often adopt a fixed clamping length and cannot conveniently adjust the tension state of the cable under different seasonal temperature conditions. This results in that under the influence of factors such as extreme weather conditions, power load changes, or the thermal expansion and contraction of the cable itself, the cable may be damaged due to excessive tension or become loose due to insufficient tension. The length and tension of the cable directly affect its electrical characteristics, such as impedance and capacitance, and further affect the voltage distribution and stability of the power system. Moreover, if the cable is too loose, it may swing and cause abrasion by rubbing against surrounding structures; if the cable is too tight, poor heat dissipation may cause the cable to overheat, which may accelerate the aging of the cable and even trigger safety accidents such as fires. Therefore, we make improvements in this regard and propose an integrated outdoor substation. Summary of the Utility Model
