Description

Technical Field

[0001] The utility model relates to a conservator device for a transformer, in particular to a conservator device for a fully sealed transformer with oil leakage monitoring. Background Technique

[0002] The transformer conservator device is commonly known as an oil conservator, which is a cylindrical container placed horizontally above the oil tank and connected to the oil tank of the transformer by a pipeline. When the transformer oil expands due to heat, the oil flows from the oil tank to the conservator; when the transformer oil contracts due to cold, the oil flows from the conservator to the oil tank. Therefore, the transformer conservator is an important component of the transformer. In the existing transformer conservators, in order to ensure the connection between the transformer oil under the action of external power and the interior of the transformer, generally, a metal bellows is used to store the transformer oil and then the metal bellows is placed in a cabinet with a vacuum state. Due to the external overflow force of the transformer oil, when the transformer oil in the metal bellows leaks, it will accelerate the leakage of the transformer oil in the cabinet, thus affecting the use safety performance of the transformer. At present, there is no component to realize the on-line monitoring of whether there is leakage in the transformer oil in the metal bellows.

[0003] The utility model effectively explores and researches at the technical level the technical problem that the metal bellows is used to store the transformer oil and then the metal bellows is placed in a cabinet with a vacuum state without monitoring the integrity of the metal bellows through the technical feature of monitoring whether the circulating transformer oil is in a single-way flow direction state.

[0049] Usage method of this embodiment: Let the transformer oil flow into the metal bellows part 12 and the interior of the transformer. Connect the air extraction pipe of the cabinet part 11 to a vacuum pump, keep the air extraction cut-off valve of the cabinet part 11 open, and keep the vacuum pump in working state to evacuate the cabinet part 11.

[0053] Its technical purpose is: To realize on-line monitoring of whether there is a leakage point in the metal bellows part 12.

[0054] When verifying the present utility model, the inventor abandoned the prior art features where metal bellows were used to store transformer oil and then placed in a cabinet with a vacuum state without monitoring the complete performance of the metal bellows.

[0056] In this embodiment, the monitoring component 3 is connected to the transformer conservator body 1 in a manner of monitoring whether there is a leakage point.

[0057] In this embodiment, it further includes a first accessory device, and the first accessory device is arranged between the transformer conservator body 1 and the monitoring component 3. The first accessory device is set as the docking plate 2.

[0058] The second embodiment of the present utility model is based on the first embodiment.

[0059] The present utility model has the following characteristics:

[0060] 1. Due to the design of the transformer conservator body 1 and the monitoring component 3, through the transformer conservator body 1, the circulation of transformer oil with the transformer is realized. Through the monitoring component 3, monitoring whether there is a leakage point in the transformer conservator body 1 and whether the circulating transformer oil is in a unidirectional flow direction state is realized, solving the technical problem of using metal bellows to store transformer oil and then placing the metal bellows in a cabinet with a vacuum state without monitoring the complete performance of the metal bellows. Therefore, the use safety performance of the transformer is improved.

[0061] 2. Due to the design of the monitoring component 3, the floating ball part 35 is realized as an observation point.

[0062] 3. Due to the design of the docking plate 2, convenient connection with the monitoring component 3 is realized.

[0063] 4. Since the structural shape is limited within a numerical range, and this numerical range is a technical feature in the technical solution of the present invention, rather than a technical feature obtained through formula calculation or a limited number of tests. Tests show that the technical feature of this numerical range has achieved good technical effects.

[0064] 5. Since the technical features of the present invention are designed, and through the combined action of these technical features alone and in combination with each other, tests show that each performance index of the present invention is at least 1.7 times that of the existing performance indexes, and it has good market value through evaluation.

[0065] There are also other technical features that are connected to the transformer oil conservator body 1 and the monitoring component 3 for monitoring whether the circulating transformer oil is in a unidirectional flow direction state, and these are all examples of the present invention. Moreover, the technical features of the above-described examples can be combined arbitrarily. To meet the requirements of the Patent Law, the Patent Implementing Regulations, and the Examination Guidelines, the embodiments of all possible combinations of each technical feature in the above-described examples will not be described one by one.

[0066] Therefore, in the technical field of oil conservator devices for fully sealed transformers with oil leakage monitoring, all technical contents that include the transformer oil conservator body 1 for connecting to a transformer and the monitoring component 3 provided on the transformer oil conservator body 1 are within the protection scope of the present invention.
