Insulating support for supporting high-pressure testing leads and use method thereof

Abstract

The invention relates to an insulating support for supporting high-pressure testing leads, which consists of a retractable insulating rod, a base, a magnet and a clamping wire slot; the cross section of the insulating rod is circular; the semicircular clamping wire slots of the two fixed testing leads are arranged on the top of the retractable insulating rod; the two semicircular clamping wire slots has an upward opening and a downward opening; the base is a semi-spherical structure; and the magnet is arranged in the semi-spherical base. When in use, the length of the insulating rod is adjusted according to the testing spot; the base is attached at the proper position on the shell of the device or the inner wall of the device vertically or horizontally or in an inverse suspension manner; and the high-pressure testing lead is hung on the proper semicircular clamping wire slot. The insulating support is simple in structure, convenient to manufacture, low in cost and convenient to use; once the insulating support is fixed, whatever leads can be spanned to the support; the support is safe and convenient; after the leads are fixed, the insulating support is firm and beautiful; simultaneously, the insulating support does not influence the testing result.

Description

technical field [0001] The invention relates to an insulating support for supporting high-voltage test lead wires in power system operation and a use method thereof. Background technique [0002] At present, in the power network, whether it is a transformer, a switch, a transformer, a surge arrester, etc., a high-voltage test must be performed on the insulation of the primary equipment to check the insulation status of the primary equipment. The nature of the test is generally divided into two types: handover test (before initial installation and commissioning) and preventive test (regular inspection after periodic inspection). The high voltage test is divided into: 1. Insulation resistance test; 2. DC withstand voltage test; 3. AC withstand voltage (also divided into power frequency withstand voltage and double frequency withstand voltage, etc.) test, etc. All the above-mentioned tests are conducted from different test instruments through the test line, that is, the high-v...

Problems solved by technology

The past practice is: hang the high-voltage lead wire with an insulating rope or an insulating plastic tape, and the two ends of the insulating rope or insulating plastic are respectively wound around other non-tested equipment. The disadvantages of this are: 1), During the test, if the insulating rope or insulating rubber-plastic belt suddenly loosens or the insulating plastic belt is torn off, a. The high-voltage lead wire is suddenly grounded and may damage the equipment under test. b. The high-voltage lead wire is suddenly grounded and may damage the test equipment. It is sometimes difficult to meet the requirements of the test conditions if the rope or insulating plastic tape is wound around other non-tested equipment
