Description

TECHNICAL FIELD

[0001] The application relates to a loudspeaker type spark gap charged detection porcelain insulator device and belongs to the technical field of power system equipment. BACKGROUND

[0002] The insulator installed on an overhead line mainly plays a supporting wire and insulation role, and can be divided into three types of ceramic, glass and composite material according to the material. In operation, the porcelain insulator is subjected to electrical and mechanical effects, which can cause the resistance of the porcelain insulator to decrease. In the process of power inspection, a spark gap detector is usually used to detect the resistance of the porcelain insulator under charge. The spark gap detector is fixed on a thin insulating plate by two metal probes. When the two probes are overlapped on the steel caps or metals at two ends of the porcelain insulator, respectively, the gap on the insulating plate will discharge and emit a sound, and an operator can determine whether the porcelain insulator is good or not according to the sound.

[0003] However, in the process of charged detection of the porcelain insulator of the transmission line, the discharge of the gap on the insulating plate and the emitted sound are usually only about 20 decibels. The sound of the gap discharge is often not clear due to the loud construction sound of the surrounding construction site, the loud bird and insect calls in the forest and the strong wind and other external factors, which brings great trouble to the charged detection of the porcelain insulator. If the damaged insulator cannot be found, the transmission line may be seriously damaged, and therefore, improvement is urgently needed.
