Evaluation of transformer scrap

Transformer scrapping refers to the state of the transformer that can no longer be used. It generally occurs when the life of the transformer ends, or a major fault occurs that cannot be repaired and has no further value for use. The end of life of a transformer means that it needs to be replaced or disposed of, and it can no longer be used. For scrapped transformers, they need to be processed in time to maintain the environment and safety.

As an independent third-party appraisal agency under Guoke Holdings, Zhongke Testing has the qualifications for fixed asset scrapping appraisal. Based on the list of assets to be scrapped and assessed and related information provided by the client, it can organize technical personnel to evaluate the assets to be scrapped and evaluate, and issue a transformer scrapping appraisal report.

(1) Special equipment has serious accident risks, including the following situations and should be scrapped:

1, produced without a license, eliminated by the state, has been scrapped or has reached the scrapping conditions, and continues to be used;

2, continues to be used without supervision and inspection or has failed inspection and testing;

3, safety The accessories and safety protection devices are missing or malfunctioning and continue to be used;

4. There has been an accident or there is an obvious fault, but the product is not fully inspected and the potential for accidents has been eliminated before continuing to be used;

1. Appearance standard: The appearance of the transformer may be burned, deformed, cracked, etc., and cannot be restored to normal condition.

2. Internal structure standards: There are abnormal noise, vibration, heat and other phenomena inside the transformer, and there are signs that the fault may affect the operational safety of the transformer.

3. Insulation standards: The insulation layer of the transformer has breakdown, damage, aging, cracking, etc., and cannot be restored through cleaning, drying, etc.

A certain electric power company has a batch of transformer equipment that is idle. In order to determine whether this batch of equipment has reached the scrapping condition, our company has been entrusted to appraise whether this batch of transformer equipment has reached the scrapping status.

Appraisal analysis results:

Appraisal analysis The expert group conducted on-site inspection and survey results on the transformer equipment commissioned for appraisal and evaluation, and made the following suggestions and conclusions:

The main structural components of this batch of transformers are damaged, and the accessories have stopped production. Even after repair, the performance is still less than two-thirds of the performance of new products, and it is recommended to be scrapped.

1. Equipment list sorting: First, it is necessary to sort out the list of all equipment, including the name, model, specification, quantity, purchase date and other information of the equipment.

2. Equipment condition assessment: Evaluate the condition of the equipment based on its usage and maintenance records. It can be carried out through regular inspections, random inspections, etc.

3. Expert appraisal: For some highly professional equipment, experts in related fields need to be invited for appraisal. Experts can evaluate the condition of the equipment based on its performance testing, technical indicators and other factors.

4. Processing decision making: Based on the identification results of the device, make corresponding processing decisions. If the equipment can be repaired or upgraded, it needs to be processed accordingly; if the equipment cannot continue to be used or the repair cost is too high, it needs to be scrapped.

5. Execution of equipment scrapping: Dispose of scrapped equipment in accordance with relevant regulations and procedures. For example, recycling, dismantling, and destruction of equipment. At the same time, appropriate record and file management work needs to be done.
