Description

Technical Field

[0001] The utility model relates to the technical field of GIS ultra-high frequency sensors, in particular to a GIS ultra-high frequency sensor fixing device. Background Art

[0002] With the development of power grid construction, the number of GIS substations is increasing. However, once an insulation fault occurs in the substation during operation, it is very easy to develop into equipment failure, disrupting the normal operation of the power system and causing adverse effects on the national economy and normal social order. Among them, partial discharge is an important factor leading to GIS equipment failure. Taking ultra-high frequency partial discharge detection as one of the live test items of GIS equipment makes it easy to find potential faults of GIS (gas-insulated metal-enclosed combination switchgear), so that the staff can timely evaluate the equipment status and effectively prevent accidents, which is of great significance to maintaining the safe operation of GIS equipment.

[0003] After searching, a GIS ultra-high frequency sensor operating device with publication number CN201720034000.2 is found, comprising an insulating operating rod and a GIS ultra-high frequency sensor clamping part arranged at the right end of the insulating operating rod, the GIS ultra-high frequency sensor clamping part comprises a semi-frame fixing frame and a movable frame slidably arranged on the inner side of the semi-frame fixing frame through a dovetail structure, the right ends of the semi-frame fixing frame and the movable frame are both provided with a stepped blind hole, the diameter of a section hole on the left side of the stepped blind hole is larger than the diameter of a section hole on the right side, a sliding rod is inserted in the stepped blind hole, a stopper is arranged at the left end of the sliding rod, and the sliding rod is An angular clip is arranged at the right end, a compression elastic member is sleeved on the sliding rod and the compression elastic member is located between the stop block and the right end of the left section hole of the stepped hole, the angular clip on the semi-frame fixing frame and the angular clip on the movable frame are arranged opposite to each other, and a GIS ultra-high frequency sensor clamping part is arranged at the end of the insulating operating rod. During detection, the GIS ultra-high frequency sensor is first tightly clamped on the GIS ultra-high frequency sensor clamping part, and then the tester only needs to hold the insulating operating rod to press the GIS ultra-high frequency sensor against the part to be tested to complete the partial discharge detection. The operation is very convenient and saves time and effort. In addition, the insulating operating rod and the semi-frame fixing frame adopt the mode of matching a single-ear plate and a double-ear plate hinge seat, and an arc plate with a plurality of through holes is arranged at the end of the single-ear plate, so that the angle between the GIS ultra-high frequency sensor clamping part and the insulating operating rod can be adjusted according to the actual working environment, and after the angle is adjusted, the GIS ultra-high frequency sensor clamping part is locked to the end of the insulating operating rod by a second fastener arranged in the through hole and the jack. The existing ultra-high frequency sensor fixing device is generally hand-held by the staff, which is time-consuming and labor-intensive, and the detection result may be affected by the loose contact between the sensor and the device under test; especially for large-scale GIS, which has the characteristics of complex structure and different heights, it is difficult to place the ultra-high frequency sensor, which reduces the work efficiency of the staff and also poses a threat to the personal safety of the staff; during the detection process, the staff may make mistakes due to fatigue and other reasons.
