Abstract
The invention relates to the power application field, specifically to a remote discharging sphere gap controlling apparatus for a cable fault test. The remote discharging sphere gap controlling apparatus mainly comprises a case body, a remote-control case, a telescopic rod, metal balls and a high-voltage insulating wire, wherein the remote-control case when remotely controlled by a remote controller controls the telescopic rod to extend and retract within a housing of the telescopic rod so as to adjust the gap between the two metal balls. Manually adjusting the distance of discharging ball gap is replaced by remote controlled automatic adjusting through the remote discharging sphere gap controlling apparatus, so that the distance of discharging ball gap can be changed without powering off a charging device. The discharging energy matches with the insulating resistance of a fault point to ensure optimal discharging sound and effects. The remote discharging sphere gap controlling apparatus is a totally-enclosed apparatus, has excellent insulating effect. Compared with a conventional manual sphere gap apparatus, the apparatus is safer, greatly improves work efficiency and is an important and necessary apparatus for a cable fault test.
