Portable cable fault detection high-voltage capacitor

Abstract

The invention relates to a portable cable fault detection high-voltage capacitor. The capacitor comprise a shell, an insulator arranged on the shell and a lead column arranged in the insulator, wherein capacitor core groups containing capacitor cores are arranged in the shell, an insulation sleeve is arranged between the capacitor core groups and the shell, insulation boards are arranged among the capacitor core groups; capacitor cores distributed side by side compose parallel cores which are in parallel, upper parallel cores combine with lower parallel cores to form the capacitor core groups; in the capacitor core groups, capacitor cores composing the parallel cores are combined together through horizontal connection pieces on end faces, the upper parallel connection pieces combine with the lower parallel connection pieces through vertical connection pieces; parallel connection pieces on the front end face or back end face are connected together in the space between adjacent capacitor core groups; leadout wires connected with the lead column are connected with the vertical connection pieces of two outermost capacitor core groups. The high-voltage capacitor has the advantage of small volume, light weight, large impact energy and simple wiring and is easy to carry.

Description

technical field [0001] The invention relates to a capacitor, in particular to a high-voltage capacitor for portable cable fault detection. Background technique [0002] With the rapid development of my country's electric power industry, cables are widely used in urban and rural power supply, transportation, communication, factories and mines. Accompanied by the sharp increase in the number of uses, it has become one of the main hidden dangers of safe power supply. Since most of the cable lines are buried underground, it is difficult to find the fault point when the power cable fails. With the advancement of science and technology, the cable fault detector has been popularized and applied, and it has become a reality to accurately determine the cable fault point without excavation. However, most of the cable buried lines are inconvenient for vehicles to use. In the past cable fault detectors, the key high-voltage pulse capacitors are large in size and heavy in weight. In ad...

Problems solved by technology

However, most of the cable buried lines are inconvenient for vehicles to use. In the past cable fault detectors, the key high-voltage pulse capacitors are large in size and heavy in weight. In addition to the transformer and the control part, a set of equipment weighs more than 100 kilograms. The detection efficiency is low and labor-intensive. Time-consuming, and will cause incalculable power outage losses
