Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the present embodiment, and it is apparent that the embodiments described below are only a part of embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the scope of protection of this patent.

As shown in the drawings, an expander housing comprises a housing 10, a viewing panel 20 and a height release mechanism 40; the cover body 10 covers the expander, and the lower part of the cover body is arranged on an oil conservator of the mutual inductor. Three observation windows 11 are uniformly distributed on the side surface of the cover body 10, and the observation panel 20 is embedded in the observation windows 11 through a sealing ring 30. Can realize multi-azimuth observation, and provide convenience for on-site product inspection. The section of the sealing ring 30 is in an S-shaped bent shape; the viewing panel 20 is arcuate in cross-section. The observation view to the internal working condition of the cover body 10 is effectively increased through the observation panel 20 with the arc-shaped cross section, and potential risks possibly occurring in the cover body 10 are timely found and judged so as to timely make an emergency plan. A first embedded groove with a downward opening is formed in the inner side of the sealing ring 30, and a second embedded groove with an upward opening is formed in the outer side of the sealing ring; the observation panel 20 is arranged inside the cover body 10 and corresponds to the observation window 11; the observation panel 20 is matched with the first embedded groove, and the second embedded groove is coated on the inner edge of the observation window 11; the edge dimension of the viewing panel 20 is larger than the dimension of the viewing window 11. So that the edge forming the viewing panel 20 has a degree of overlap with the edge of the viewing window 11. The pressure of the liquid inside thereby presses the viewing panel 20 outward, improving the overall sealing performance.

The cross section of the cover body 10 is circular; the curvature of the arc of the cross section of the viewing panel 20 is the same as the curvature of the enclosure 10. The convenience of installation has been improved.

The sealing ring 30 is made of silicon rubber. It has excellent weather resistance and high anticorrosive capacity, and may be used in harsh condition for long period.

The observation panel 20 is made of tempered glass. The glass has the advantages of high transparency, corrosion resistance and aging resistance, and the service cycle is prolonged.

The height releasing mechanism 40 is disposed at the lower portion of the housing 10. The height releasing mechanism 40 is used for responding to the abnormal lifting condition of the expander, so that effective buffering is formed, and damage to equipment is avoided.

The height releasing mechanism 40 comprises a fixing hole 41, a fastening piece 43 and a communication slot hole 42; the fixing holes 41 are provided with a plurality of fixing holes and are uniformly distributed at the lower part of the cover body 10 in a surrounding manner, and the fastening pieces 43 penetrate through the fixing holes 41 to be connected with the oil conservator of the transformer so as to be convenient for installing and fixing the cover body 10; the fixing hole 41 is communicated with the outside of the lower edge of the shield body 10 through the communication slot hole 42. The communication slot 42 is vertically arranged. The resistance of the fastener 43 passing through the communication slot 42 is effectively reduced. When the height of the expander is abnormally changed, the cover body 10 moves upwards under the jacking action of the expander, and in the process of moving upwards, the fastening piece 43 enters the communicating slotted hole 42 to make adaptive buffering, so that the adaptability of the cover body 10 to the height change of the expander is improved.

The housing 10 on one side of the viewing window 11 is provided with a signboard formed by screen printing. The indication mark is clear and visible, and the requirement of long-term reliable use outdoors on site can be met.

And the cover body 10 on one side of the observation window 11 is provided with scale marks convenient for measuring the liquid level height.

According to the expander outer cover, the multi-direction observation of the working condition view in the cover body is effectively increased through the observation panel with the arc-shaped cross section, and potential risks possibly occurring in the cover body are timely found and judged so as to make an emergency plan timely; meanwhile, the height releasing mechanism is used for dealing with the rising abnormal condition which may occur to the expander, so that effective buffering is formed, and the damage to equipment is avoided. The sealing ring with the s-shaped section forms a labyrinth type sealing structure between the observation panel and the observation window, so that the sealing degree is improved.
