Description

Technical Field

[0001] The utility model relates to the field of high-voltage combined electrical equipment power transmission, in particular to an observation window structure suitable for a combined electrical equipment test busbar. Background Art

[0002] With the development of society, the power system plays an increasingly important role in people's daily lives. As a new type of electrical device that appeared in the mid-1960s, the combined electrical system (GIS) has been vigorously developed since its inception due to its small footprint, immunity to environmental influences, low noise, low radio interference level, safe and reliable operation, and low maintenance workload. It has now become an indispensable part of the power system.

[0003] GIS is primarily used for the control, protection, and measurement of substations and transmission lines. To ensure the long-term and stable operation of GIS equipment, it undergoes a series of inspections and verification tests before leaving the factory, especially during the design and development of new products. However, existing GIS busbar structures do not contain visual observation windows, making it impossible to observe the actual status of busbar components during the test. This hinders the analysis of test results and, to a certain extent, reduces the timeliness of new product development. Utility Model Content

[0004] The utility model aims to solve the problem that the GIS busbar structure in the background technology does not have a visual observation window and the real state of the busbar internal components during the test process cannot be observed, and proposes an observation window structure suitable for the combination electrical test busbar.

[0005] The technical solution of the utility model is: an observation window structure suitable for a combination electrical appliance test busbar, comprising:

[0006] A support tube is provided on the busbar housing;

[0007] An observation window flange is provided on the end of the support tube away from the busbar housing;

[0008] An observation window is provided on the observation window flange;

[0009] and a pressing plate, which is arranged on the observation window flange and presses the observation window.

[0010] Preferably, the support tube and the busbar housing are connected by welding.

[0011] Preferably, the support tube and the observation window flange are connected by welding.

[0012] Preferably, the pressure plate is detachably connected to the observation window flange via a connector.

[0013] Preferably, an annular groove is provided on the surface of the pressing plate that contacts the observation window, a sealing ring is provided in the annular groove, and the sealing ring and the observation window are squeezed and fitted.

[0014] Preferably, an annular groove is provided on the observation window flange, a sealing ring is provided in the annular groove, and the sealing ring and the observation window are squeezed and fitted.

[0015] Compared with the existing technology, the utility model has the following beneficial technical effects: the support tube is welded to the busbar shell, the observation window flange is welded to the support tube, the observation window is placed in the observation window flange, and finally the observation window is pressed and fixed by a pressure plate, and at the same time sealed by a sealing ring to prevent leakage. The internal structure of the busbar can be observed through the transparent observation window without disassembling the busbar air chamber. It has the characteristics of simple structure, easy manufacturing, safety and reliability, and has good practicality and promotion prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Example 1

[0019] like Figure 1 As shown, the utility model proposes an observation window structure suitable for a combination electrical appliance test busbar, comprising:

[0020] Support tube 1, arranged on the busbar housing;

[0021] The observation window flange 2 is provided on the end of the support tube 1 away from the busbar housing;

[0022] An observation window 4 is provided on the observation window flange 2 and is made of organic glass;

[0023] and a pressing plate 3 , which is arranged on the observation window flange 2 and presses the observation window 4 .

[0024] Example 2

[0025] like Figure 1 As shown, the present invention proposes an observation window structure suitable for a combination electrical test busbar. Compared with the first embodiment, this embodiment introduces the matching connection structure between the various components.

[0026] The support tube 1 is welded to the busbar housing. The support tube 1 is also welded to the observation window flange 2. The pressure plate 3 is removably connected to the observation window flange 2 via connectors 6. In an optional embodiment, connectors 6 are bolts, and multiple connectors 6 are provided. An annular groove is provided on the surface of the pressure plate 3 that contacts the observation window 4. A sealing ring 5 is positioned within the groove, forming a press-fit fit between the sealing ring 5 and the observation window 4. An annular groove is provided on the observation window flange 2, and a sealing ring 5 is positioned within the groove, forming a press-fit fit between the sealing ring 5 and the observation window 4.
