Embodiment Construction
[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0017] Such as figure 1 , figure 2 As shown, the present invention includes a steel bent structure body 1, which is located on the foundation 2 below the ground, and the steel bent structure body 1 is composed of a clear height × clear span × net length of an internal space ≥ 50m × 60m × 86m test hall 3. The clearance size in the test hall 3 is mainly determined by the overall dimensions of the equipment in the test hall 3, the size of the sample and the safety distance during the test. The roof of the steel bent structure body 1 adopts the quadrangular pyramid bolt ball grid structure in the prior art, and the outer walls of the steel bent structure body 1 are provided with outer wall panels.
[0018] In order to realize the function of not being disturbed by external electromagnetic waves when performing partial discharge and radio interference ...

The invention relates to a special high-voltage power transmission and transformation testing hall, comprising a steel bent frame structure which is ground on the underground basis, a roof of the steel bent frame structure is a quadrangular pyramid bolt-sphere grid structure, the peripheral outer wall surface of the steel bent frame structure is provided with an outer wall board, shielding steel boards are arranged on the peripheral inner wall surface of the steel bent frame structure and a ceiling, a shielding steel board network is arranged between the bottom surface of the steel bent framestructure and the basis, the back surfaces of the shielding steel boards are provided with sound deadening materials, the net height multiplied by net span multiplied by net length of the internal space of the testing hall is not less than 50m multiplied by 60m multiplied by 86m; the testing hall is internally provided with various testing devices, the shielding effect of the testing hall is morethan 70dB, the frequency range is 0.5 to 1.6MHz, and the reverberation time under 500Hz is less than 5 seconds. The testing hall can be widely used in various special high-voltage power transmission and transformation tests.
Description
technical field [0001] The invention relates to an electric power test facility, in particular to an ultra-high voltage power transmission and transformation test hall. Background technique [0002] The power transmission and transformation test hall is a kind of power test device, the UHV power transmission and transformation test hall, in terms of its scale and equipment technical parameters (including the space scale in the test hall, the shielding performance of the test hall, the safety distance of the equipment in the test hall and The specific technical parameters of the equipment, etc.), need to meet the requirements of the high pressure test. However, the existing domestic power transmission and transformation test halls have relatively low voltage levels, which cannot meet and carry out the requirements of testing and research on the insulation performance of UHV power transmission and transformation equipment. Contents of the invention [0003] In view of the a...
