Embodiment 1

[0030] Embodiment 1: as figure 1 As shown, a method for testing the insulation resistance of a power line includes that the test method requires at least two testers to operate, wherein one tester observes the insulating bracket 201 to support the test instrument 202, and the other tester uses an insulating operating rod to insulate 204 Connect the meter probe 210 connected to the meter wire 203 to the fault test point. 102

[0031] Because adopting said test method requires at least two testers to operate, one of them observes the insulating support to support the test instrument, and the other tester insulates and uses an insulating operating rod to connect the instrument probe connected to the instrument line to the fault test point. When using the insulation support of the insulation resistance tester, the operator should wear insulating boots and gloves. Two people operate, one observes the instrument, and pays attention not to touch the instrument and the instrument lin...

Abstract

The invention belongs to technical field of power line insulation resistance testing and particularly to a power line insulation resistance test method and a tester insulation support. It requires at least two testers to operate the test method, one tester observes the insulation support and supports a test instrument, and the other tester enables an instrument probe connected with an instrument wire to be in contact with a fault test point by using an insulated operating rod. Further, the present invention also provides a power line insulation resistance tester insulation support. The method solves a problem that a power overhaul worker has a high electric shock risk in the prior art when searching out fault points and performing an insulation resistance test at the field because an operating site is full of water, muddy, and poor in insulation condition and safety measures, such as connecting a ground wire to the line and switching on a ground knife switch, cannot be achieved. The method has technical effects of preventing electric shock of workers and the instrument operator, protecting personal safety in operation, and reinforcing footsteps.

Description

technical field [0001] The invention belongs to the technical field of power line insulation resistance testing, and in particular relates to a power line insulation resistance testing method and an insulating support for a tester. Background technique [0002] The thunderstorm season is a period of frequent grounding and tripping faults of power lines. In the existing technology, when electric power maintenance personnel search for fault points and conduct insulation resistance tests on site, the work site is waterlogged, muddy, and the insulation conditions are extremely poor, and hanging on the line cannot be used. Safety measures such as grounding wires and grounding knife switches pose a very high risk of personal electric shock to operators. Contents of the invention [0003] The present invention provides a method for testing the insulation resistance of a power line and an insulating support for a tester to solve the problems in the prior art mentioned in the above...
