Problems solved by technology

[0002] At present, most of the test racks used for the detection of distribution line fault indicators use floor-standing, small-line, no-voltage and low-current methods for line simulation. The number of tested products is small, and 10kV voltage and line current cannot be applied at the same time. The insulation problem is more prominent. In order to ensure the insulation, there is generally a personnel isolation zone around it, but there is still the risk of personnel entering or touching by mistake during the detection process, causing great safety hazards and occupying a large area.

Abstract

The invention provides a lifting test stand of a distribution line fault indicator. The test stand is composed of a lifting mechanism, an insulating connecting bracket and a test coil that are connected successively from top to bottom. The insulating connecting bracket consists of a support frame and an insulation bracket. The test stand has advantages of great convenience in operation, high safety, small occupied area, and large detection number; and the checking and testing efficiency of products at all links is improved.

Description

technical field [0001] The invention belongs to the detection field of a distribution line fault indicator, and in particular relates to a lifting test frame for a distribution line fault indicator. Background technique [0002] At present, most of the test racks used for the detection of distribution line fault indicators use floor-standing, small-line, no-voltage and low-current methods for line simulation. The number of tested products is small, and 10kV voltage and line current cannot be applied at the same time. The insulation problem is more prominent. In order to ensure the insulation, personnel barriers are generally set up around it, but there is still the risk of personnel entering or touching by mistake during the detection process, causing great safety hazards and occupying a large area. [0003] Therefore, it is necessary to provide a distribution line fault indicator lifting test stand that can realize simultaneous application of 10kV voltage and current, is co...
