Description
Technical Field
The invention relates to a tool for fixing a direct-current wall bushing, in particular to a high-voltage test support capable of simulating a real operating environment.
Background
The direct current wall bushing is one of the important devices of extra-high voltage direct current transmission, and the function of the direct current wall bushing is to safely penetrate a high-voltage lead through an insulating wall so as to be connected with other devices. Because the operating environment of direct current wall bushing is more abominable, because the electrical accident that its dielectric strength worsens and lead to takes place very frequently, consequently, it is essential to carry out delivery test, handing-over test and prevention test to it. The direct-current wall bushing test support is a tool for simulating a field service environment to perform a high-voltage test. According to the domestic and foreign test standards, the high voltage test of the direct current wall bushing must be according to the design requirements, and the installation height and the inclination angle must be consistent with the design values, so as to achieve the electric field distribution of the actual operation.
The existing sling type test support has certain requirements on the insulation strength of a sling and has poor safety. The framework type test support can achieve a good insulation effect, but the DC wall bushing has uneven weight on the outdoor side and the indoor side, so that the requirement on connection firmness is high. Firstly, as the voltage level of the wall bushing is increased, the safety distance of the test equipment in the high-voltage test hall is increased, so that the height of the test support needs to be increased. Secondly, the inclination angle of the direct current wall bushing has a large influence on the electric field distribution in the test, and the inclination angles of the wall bushings of different models are different. At present, the mechanical strength of the through-wall sleeve with the weight of several tons cannot meet the requirement by adopting a method of adjusting the angle of a turbine wheel rod. Thirdly, with the improvement of the designed voltage grade of the domestic extra-high voltage test hall, the safety distance between the devices is more and more far, and when a plurality of test projects are completed, a tester needs to frequently move the test support and the sleeve to a specified test area. All existing test supports do not have a moving function, and only can the sleeves be detached from the supports and then are separated by a traveling crane to move to a designated place and then are hoisted again. The method not only greatly reduces the working efficiency, but also has higher safety risk in the operation process.
