Problems solved by technology
[0002] Transformers are important pivotal equipment in the power system. With the increase in capacity and quantity and the expansion of the grid scale, if a problem occurs, it will have a huge impact on the transformer, which may cause the transformer to trip and cause a large-scale power outage. In order to ensure the safety of the transformer, It is necessary to use the transformer oil conservator. In order to improve the positive pressure effect of the transformer oil conservator on the transformer, a volume expansion bladder is installed in the transformer oil conservator. Therefore, the volume expansion bladder used in the transformer oil conservator is an important Transformer parts, in the existing volume expansion capsule used for transformer oil conservator, when the volume expansion capsule of the outer oil type metal corrugated oil conservator performs telescopic movement, the problem that is prone to occur is that the inner cavity is stuck, Thus affecting the positive voltage effect on the transformer and reducing the safety performance of the transformer

A guide rail device for a volume expansion capsule of a transformer oil conservator, comprising a guide rail (1 ), the connecting device arranged between the guide rail (1) and the inner wall of the transformer oil conservator, the volume expansion bladder arranged between the guide rail (1) and the volume expansion bladder of the transformer oil conservator and used for the transformer oil conservator The guide device that the body moves along the guide rail (1), fix the guide rail (1) in the transformer oil conservator through the connecting device, and ensure that the volume expansion bladder of the transformer oil conservator moves along the guide rail (1) through the guide device, ensuring The volume expansion capsule of the transformer oil conservator does not get stuck, and the volume expansion capsule of the transformer oil conservator is no longer directly used, thus improving the reliability of the positive pressure on the transformer and improving the safety performance of the transformer .
Description
1. Technical field [0001] The invention relates to a guide rail device for a volume expansion bladder, in particular to a guide rail device for a volume expansion bladder of a transformer oil conservator. 2. Background technology [0002] Transformers are important pivotal equipment in the power system. With the increase in capacity and quantity and the expansion of the grid scale, if a problem occurs, it will have a huge impact on the transformer, which may cause the transformer to trip and cause a large-scale power outage. In order to ensure the safety of the transformer, It is necessary to use the transformer oil conservator. In order to improve the positive pressure effect of the transformer oil conservator on the transformer, a volume expansion bladder is installed in the transformer oil conservator. Therefore, the volume expansion bladder used in the transformer oil conservator is an important Transformer parts, in the existing volume expansion capsule used for transfo...
