Background

In recent years, with the aggravation of environmental pollution, more and more haze weather appears, and the normal life of people is seriously influenced. In order to prevent and control haze, the nation proposes a plan for controlling haze by trans-regional power transmission, and trans-regional power transmission is long-distance power transmission and needs to adopt extra-high voltage and other power transmission modes, which brings great development opportunity for extra-high voltage engineering.

Generally, energy sources in regions such as inner Mongolia autonomous regions, Heilongjiang, Jilin and Xinjiang are abundant, and the construction of extra-high voltage power grids is greatly promoted in the regions, so that the extra-high voltage power grids can play an important role in transregional power transmission. The areas are in high and cold areas, and the installation time of the extra/ultrahigh voltage transformer in the construction process of the extra-high voltage transformer substation spans the whole winter; therefore, the construction process of the extra-high voltage transformer substation needs to face the original technical problem and also needs to meet the requirement of the extra-high/extra-high voltage transformer in the high and cold low-temperature area on the environmental temperature during winter construction.

For example: in the installation process of the extra/ultrahigh voltage transformer, the requirement of insulating oil in the extra/ultrahigh voltage transformer is high, the index requirement is high, and the hot oil circulation temperature of the insulating oil must reach 65 +/-5 ℃ so that the extra/ultrahigh voltage transformer can be normally installed; however, the outdoor environment temperature in winter in the alpine region is usually below-20 ℃, so that the temperature difference between the outdoor environment temperature in winter in the alpine region and the hot oil circulation temperature of the insulating oil reaches more than 80 ℃, the heat loss of the insulating oil is serious, and the stability of the installation and subsequent operation of the extra/ultrahigh voltage transformer is affected.

In addition, in the process of mounting the extra/ultrahigh voltage transformer in the alpine region, the metal shell of the extra-high voltage gas insulated metal enclosed switchgear (also called extra-high voltage GIS) is fast in heat conduction and difficult to preserve heat. Therefore, in order to solve these problems, it is necessary to provide a thermal insulation device that satisfies both the extra-high voltage transformer and the extra-high voltage GIS, so as to ensure smooth installation of the extra-high voltage transformer under low temperature conditions.

However, although some existing national standards and enterprise standards correspondingly specify the installation and test of electrical equipment, there is no regulation about the temperature requirement problem in the installation process of the extra/ultra high voltage transformer.

The number of the bushing mounting holes is determined according to the number of the bushings 31 to be mounted in the extra/high voltage transformer, for example, when the medium voltage bushing and the high voltage bushing of the extra/high voltage transformer 3 are mounted, two bushing mounting holes need to be formed in the ceiling 2 so that the medium voltage bushing and the high voltage bushing of the extra/high voltage transformer 3 can extend out of the heat insulation shed. In addition, a sealing tarpaulin can be arranged at each sleeve mounting hole, and the sleeve mounting holes can be sealed through the sealing tarpaulins when the sleeve mounting holes are not needed.
