Description

Technical Field

[0001] The utility model relates to the field of conservators, and particularly to a capsule-type conservator. Background Art

[0002] A capsule-type conservator is an accessory of a transformer, 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. The capsule-type conservator has the characteristics of good sealing performance, no evaporation and loss of oil products due to long-term storage, replaceable capsule, and long service life.

[0003] The Chinese invention patent with the publication number CN106531405B discloses a use method of a conservator with a built-in detection of capsule leakage. The conservator with a built-in detection of capsule leakage is provided with a conservator capsule inside. The conservator capsule is slightly smaller than the internal cavity of the capsule conservator. A magnetic marking oil level gauge is provided on the side end cover of the capsule conservator. The upper part of the magnetic marking oil level gauge communicates with the top of the capsule conservator, and the lower part of the magnetic marking oil level gauge communicates with the bottom of the capsule conservator; a float type oil level gauge is provided on the side wall of the capsule conservator. The float type oil level gauge includes a guide rod and a float. The float is located inside the capsule conservator, between the conservator capsule and the transformer oil. This kind of conservator is often only supported at the float. When the float is at the lowest oil level, the guide rod remains horizontal. However, it is found in the actual use process that the guide rod will generate creep deformation due to its own gravity during long-term use, resulting in the oil level gauge being unable to correctly indicate the true oil quantity of the conservator.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] In order to improve or solve the technical problem that the guide rod generates creep deformation during long-term use in the prior art, resulting in the oil level gauge being unable to correctly indicate the true oil quantity of the conservator, the utility model provides a capsule-type conservator.
