Abstract

The invention discloses a three-phase output test transmission instrument, which belongs to the technical field of electric power detection and comprises a box body and a test accessory, the box body comprises a detection device and an operation and display panel which are arranged in the box body, and three high-voltage output parts for testing are arranged on the operation and display panel. And the three high-voltage output parts for testing are connected with a detection device in the box body. During on-site testing, three high-voltage output parts for testing of an instrument can be respectively hung on an A-phase line, a B-phase line and a C-phase line before testing, so that the hanging workload is reduced; the high voltage is applied simultaneously and is close to the actual working state of the power grid, so that comparison and judgment are facilitated, the trial transmission success rate is increased, and the working efficiency is improved finally.

Description

technical field [0001] The invention relates to the technical field of electric power detection, in particular to a three-phase output test delivery instrument. Background technique [0002] Electric lines are widely used in my country's power supply system. After a fault occurs, it is necessary to use a DC tester or an AC tester to troubleshoot and test the distribution line. The existing DC tester or AC tester are both. It has a high-voltage output part, which is connected to the line for testing. Since all lines are composed of three-phase A, B, and C, when using on-site, many times, it is often necessary to connect the high-voltage output part of the instrument. Hook up to A, B, C three-phase lines respectively for testing. Since the line is relatively high off the ground, repeated hooking will have a certain workload. Moreover, in the testing process, it is often necessary to compare and judge the three-phase test results. When the test is connected separately, it may be...
