Abstract
The utility model discloses a sensor stabilizing device, used for a supersonic partial discharge test for a gas insulated substation. When the device is used, a probe of a sensor is fixedly disposed on a sensor fixing device, and then the probe is pointed to a test point according to actual test requirement. Since the top end of a limited rod is higher than the sensor fixing device, when the probe of the sensor contacts the test point, the limited rod has already firmly abutted around the test point, forming triangular fixation, and limiting all-around freedom degree of the probe. The probe can just move forward and backward, and a support rod is pressed by forces, so the probe of the sensor tightly fits the test point. Then the supersonic partial discharge test can be performed, and stable measurement is realized through the limited rod, and possibility that bad noise signals are caused by probe vibration is reduced.
