Embodiment
In order to technology feature of the present utility model, object and effect are had understanding clearly, now compare accompanying drawing and embodiment of the present utility model be described:
As shown in Figure 1, the ultra-high voltage porcelain bushing sound detection support that shakes that is applicable to of the present utility model comprises: at least one column 1, and column 1 outer wall has offered multiple open holes 11, sensor 2 can be installed in multiple open holes 11 any one. The scope of extra-high voltage is: 75kv～750kv. Using the ultra-high voltage porcelain bushing sound that is applicable to of the present utility model to shake before detection support, first processing mounting holes 11 on column 1, during the position of open holes 11 can be tested according to reality, the position at the tested position of ultra-high voltage porcelain bushing process; At scene, when the crackle of ultra-high voltage porcelain bushing is detected, can first column 1 be moved near ultra-high voltage porcelain bushing to be detected, then, position according to the tested position of ultra-high voltage porcelain bushing, sensor 2 is installed in the open holes 11 of corresponding position, and it is outside to make sensor 2 be close to ultra-high voltage porcelain bushing to be detected, can be detected by the crackle of ultra-high voltage porcelain bushing. The ultra-high voltage porcelain bushing sound that is applicable to of the present utility model shakes detection support, when the sound carrying out ultra-high voltage porcelain bushing shakes detection, it provides a kind of convenient, fast, stable sensor moves mode so that experimentation is more convenient and reliable and stable.
