Description

Technical Field

[0001] The utility model relates to the technical field of transformer maintenance, in particular to a modular oil and gas casing rubber protective sleeve. Background Art

[0002] The total length of the transformer oil and gas bushing is about 3 meters. The middle mounting flange divides the bushing into two sections, the longest of which is about 1.9 meters and the shortest is about 1.2 meters. In order to prevent the epoxy resin on the outer surface of the bushing from being damaged, during the lifting and transportation process, a bulky steel barrel cover without elastic vibration damping protective layer was used for protection. Not only is the installation difficult, but there is still a risk of damaging the bushing. In addition, since the length of the protective cover cannot be adjusted and lacks the necessary versatility, it is necessary to design a modular rubber bushing protective ring that is easy to disassemble and assemble. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a modular oil and gas casing rubber protective sleeve, which can protect the oil and gas casing through the modular oil and gas casing rubber protective sleeve, reduce the difficulty and operation risk of oil and gas casing protection, and achieve the versatility and convenience of disassembly and assembly of the protective sleeve.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a modular oil and gas casing rubber protective sleeve, including a transformer oil and gas casing, a gas side mounting flange and a transformer side mounting flange are provided on the transformer oil and gas casing, a plurality of gas side rubber casings are connected to the gas side mounting flange, and a plurality of transformer side rubber casings are connected to the transformer side mounting flange; the plurality of gas side rubber casings are fixedly connected together by a gas side tie rod, the gas side tie rod passes through the gas side rubber casing, and the plurality of transformer side rubber casings are fixedly connected together by a transformer side tie rod, and the transformer side tie rod passes through the transformer side rubber casing.

[0005] Preferably, the ends of the plurality of gas-side rubber bushings are provided with gas-side cover plates, and the ends of the plurality of transformer-side rubber bushings are provided with transformer-side cover plates.

[0006] Preferably, both ends of the gas side tie rod and the transformer side tie rod are provided with threads and bolts for fastening.

[0007] Preferably, the inner side walls of the gas-side rubber bushing and the transformer-side rubber bushing are serrated structures.

[0008] The utility model provides a modular oil and gas casing rubber protective sleeve, which has the following beneficial effects:

[0009] 1. The rubber protective cover can be disassembled and assembled in stages, which fully reduces the difficulty of installation and realizes the convenience of disassembly and assembly. No other equipment is required for installation, and one person can complete the disassembly and assembly of the protective cover;

[0010] 2. The rubber protective sleeve has a good vibration reduction effect, and the pull rod is smooth, which can effectively prevent the sleeve from being damaged due to collision. The rubber sleeve is tightly connected to prevent water and moisture from entering;

[0011] 3. The length of the protective sleeve is adjustable, and it can be widely used in the protection of all oil and gas casings. It can also be used for the porcelain insulation protection of the lower section of oil-immersed capacitor casings. BRIEF DESCRIPTION OF THE DRAWINGS
