The product selection of the metal corrugate conservator for transformer

Vertical external oil metal corrugate conservator for transformer is latest generation of the whole sealing type conservator by Shenyang Tiangong Power Technology Co., Ltd. (Shenyang Tiangong Power Equipment Co., Ltd.) , is the all-around products with the most ideal structure and the most excellent performance, has the characteristic of good sealing, long service life, maintenance free, convenient installation, is suitable for all kinds of the power equipments such as oil-immersed transformers, capacitors and reactors.

1. The model selection of the horizontal external oil metal corrugate conservator

①Provide transformer total oil weight, min and max environment temperature for transformer use area.

②Refer to the following figure to give the relative size of transformer connection, specify special requirements, such as switch cabinet, vacuum oil filling, oil level remote transmission, oil level gauge rain cover, etc.

③The manufacturer shall cooperate to select the model of conservator, and finally determine the product structure size.

2.Selection methods

①According to the total oil weight of the transformer, check the last column of the table, and select the optimal conservator size (width and length) suitable for transformer space in the model that meets the requirements of many types.

②Calculate the minimum rated compensation of the conservator according to the total oil weight and maximum temperature difference of the transformer.

③Then, the minimum rated compensation for the design requirements is indicated in the conservator model △, which is the confirmation of the model.

Example: 240MVA/220KV transformer, the total oil weight is 50t, and the compensation amount of conservator is more than 4500dm3.

The model of the conservator is: BP3L1260x4900-4500, which is calculated by the manufacturer and the height of the conservator is 1370mm.
