Adjustable supporting bar and supporting method thereof

Abstract

An adjustable supporting bar is mainly used for supporting a high-voltage test wire. The adjustable supporting bar comprises a base, a bar body, and a wire clamp assembly. The base can be adsorbed on an object prepared from steel through magnetic force. The bar body is a telescopic insulating bar, and one end of the bar body is connected with the base through a rotating mechanism and can rotate relative to the base. The wire clamp assembly is arranged at the other end of the bar body, and can rotate relative to the bar body. The adjustable supporting bar provided by the invention is applicable to different working environments, can keep a high-voltage test wire an enough safety distance from the metal shells of test equipment and surrounding equipment, and improves the safety of high-voltage test and the working efficiency.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to an adjustable support rod and a support method thereof. Background technique [0002] The high-voltage test is an important measure to judge whether the equipment continues to be put into operation, prevent equipment damage and ensure the safe operation of the equipment. It is a very important work item in the maintenance of substation equipment.

Problems solved by technology

[0003] In the high-voltage test, the installation of the high-voltage test line connecting the test instrument and the equipment under test is a headache. Due to the complex and changeable working environment, in most high-voltage tests, the high-voltage test line is Unable to achieve the ideal suspension state

[0004] The commonly used method at present is: in the case of a suitable bracket around the tested equipment, the insulating rope can be used to support the high-voltage test line, but when the tested equipment is relatively isolated and there is no supporting frame around, the insulating rope will be lost. Its role, especially in the work of carrying out high voltage tests on main substations;

[0005] Although the gram rod can also play a good supporting role, the fixation of the gram rod is a headache. If the fixation is not firm, it will tilt and fall during the test, which will bring serious safety problems to the high-pressure test. Hidden danger

[0006] The ideal suspension state of the high-voltage test line can ensure the accuracy of the test data and the safety of equipment and test personnel, and the high-voltage test line should keep a sufficient safe distance from the metal casing of the tested equipment and surrounding equipment to prevent the high-voltage test line from appearing The phenomenon of discharge grounding will cause serious deviations in test results, and even cause damage and injury to equipment and test personnel
