Embodiment

[0027] refer to figure 1 , the present embodiment provides a method for repairing a transformer pile head after burning out; a repairing method for a transformer pile head after burning out; comprising the following steps:

[0028] S1. Check the size parameters of the screw on the transformer burnout pile head 1;

[0029] S2. Process a butt nut 2 matching the size of the screw for use, and at the same time, a bolt section 3 is arranged on the other side of the butt nut;

[0030] S3. Remove the wire clamp at the burnt pile head position on the transformer after power failure;

[0031] S4. Use a sawing device to cut off the burnt section of the pile head 1, and keep a complete pile head screw during sawing;

[0032] S5. Install the butt nut 2 on the remaining pile head screw; then install the wire clip on the bolt section 3 of the butt nut to complete the repair of the transformer pile head.

[0033] As a spare butt nut 2, it is a step structure made of copper material; the o...

Abstract

The invention discloses a method for repairing a burnt transformer pile head, and belongs to the technical field of power equipment maintenance methods and devices. The method comprises the following steps: S1, checking size parameters of a screw on a burnt pile head 1 of a transformer; s2, a butt joint nut 2 matched with the screw in size is machined for standby application, and meanwhile a bolt section 3 is arranged on the other side of the butt joint nut; s3, removing the wire clamp at the position of the burnt pile head on the transformer after power failure; s4, a saw cutting device is used for cutting off the burnt section of the pile head 1, and a section of complete pile head screw is reserved during saw cutting; s5, a butt joint nut 2 is installed on the remaining pile head screw; according to the transformer pile head repairing method, the problems that in the prior art, when the burnt-out pile head of a transformer is repaired, the needed time is long, and a large amount of manpower and material resources are consumed are effectively solved.

Description

technical field [0001] The invention relates to the technical field of electric equipment maintenance methods and devices, in particular to a method for repairing transformer pile heads after burnout. Background technique [0002] During the long-term operation of the distribution transformer, there will be failures such as pile head aging or poor contact that cause the pile head to burn out. After the transformer pile head is burnt, the wire clamp will no longer be able to clamp the wire. The current processing method is to replace the entire pile head screw. However, the traditional replacement of the transformer pile head requires core pulling, but the transformer oil will be damaged during the core pulling process. Contact with the air will easily cause the deterioration of the transformer oil and shorten the service life; it may cause damage to the transformer when the core is pulled, which leads to a long repair time for the fault and a lot of manpower and material res...
