Embodiment Construction

[0010] The present invention will be described in further detail below through specific examples. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0011] A transformer on-site verification wiring method, characterized in that: comprising the following steps:

[0012] ⑴. First, remove the primary wiring clamp of the existing calibrator, and at the same time remove the grounding wire of the existing grounding rod, and a dedicated person is responsible for connecting the primary wiring head of the calibrator to the terminal of the grounding rod; and check Whether the connection is firm.

[0013] (2) Hang the grounding rod on the primary bus of the transformer, and then check the transformer.

[0014] Working principle of the present invention is:

[0015] Since the grounding rod has a certain length, when the grounding rod is installed on the primary bus of the transformer, the staff does not need t...

Abstract

The invention relates to a mutual inductor field calibration wire-connection method which is characterized of comprising the following steps. Step 1, connect one connector lug of a calibration instrument to terminals of a ground rod, step 2, hang the ground rod on a primary bus of a mutual inductor to calibrate the mutual inductor. According to the mutual inductor field calibration wire-connection method, the ground rod has a certain length, so that a staff has no need to climb to positions equipped with the mutual inductor and avoids personal risk for high-position work when installing the ground rod on the primary bus of the mutual inductor. Besides, a mutual inductor primary device is prevented from damage, the security of the mutual inductor field calibration is effectively improved, and the efficiency of calibration work is enhanced.

Description

technical field [0001] The invention belongs to the technical field of electric power maintenance, and in particular relates to a method for on-site verification and wiring of a transformer. Background technique [0002] During on-site calibration, workers need to board the structure and transformer when disconnecting and connecting the primary line, and connect the primary wiring clip of the calibrator with the primary busbar of the transformer. Since there is no place to fix the safety belt on and around the transformer, the safety belt can only be put on the transformer, and there are potential safety hazards for the personnel and equipment of the staff. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a method for on-site verification and wiring of a transformer that is safe in operation, avoids climbing operations, and protects primary equipment from damage. [0004] The present inve...
