Abstract
Description
Technical Field
[0001] This application relates to the field of gas relay inspection window technology, and more particularly to a grooved glass plate. Background Technology
[0002] The gas relay (or methane relay) is a core non-electrical protection device in oil-immersed transformers, installed in the connecting pipeline between the transformer tank and the conservator. Its inspection window typically uses a flat glass structure to directly observe the internal gas accumulation (light methane) and oil flow status (heavy methane). Current mainstream designs, such as the QJ series (QJ-50, QJ-80, etc.), rely on this flat glass for manual inspection. Maintenance personnel need to periodically check the gas color, volume, and oil level changes through the window to assist in fault diagnosis (such as air accumulation, arc discharge, etc.).
[0003] In the process of implementing the technical solution disclosed herein, it was found that using a planar glass structure has at least the following problems:
[0004] 1. Low gas detection sensitivity: the trace gas generated by the fault is dispersed in the oil as small bubbles, which can easily adhere to the inner wall of the flat glass or be suspended in the oil, causing it to be missed by visual observation.
[0005] 2. Compressive strength depends on thickness. To meet high pressure requirements, flat glass can only achieve this by increasing its thickness. However, increasing the thickness will lead to a decrease in light transmittance and an increase in the risk of stress concentration at the center.
[0006] 3. Insufficient explosion-proof redundancy; when an internal arc fault occurs, the oil-gas mixture impacts the central area of the flat glass, resulting in a large dispersion of the rupture pressure threshold, which can easily lead to secondary oil spraying accidents.
[0007] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content
[0008] To provide a basic understanding of some aspects of the disclosed technical solutions, a brief summary is given below. This summary is not a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these technical solutions, but rather serves as an introduction to the detailed explanations that follow.
[0009] This disclosure provides a grooved glass sheet to solve the problems mentioned in the background art.
[0010] In some technical solutions, the grooved glass sheet includes: a glass sheet including a plurality of vertical slots opened along its height direction, the plurality of vertical slots being evenly distributed along its width direction and all located on a plane of the glass sheet.
[0011] Optionally, each of the vertical slots includes: a triangular prism segment formed on the plane of the glass sheet; and a triangular pyramid segment formed on the plane of the glass sheet, located at both ends of the triangular prism segment and connected to the triangular prism segment, with the tips of the triangular pyramid segments at both ends extending to the plane of the glass sheet.
[0012] Optionally, it further includes: the height of each of the triangular prism segments is in the range of 34.6mm-38.6mm; the height of each of the triangular pyramid segments is in the range of 6.5mm-6.9mm.
[0013] Optionally, the glass sheet further includes: scale lines, uniformly marked along the height direction of the glass sheet; and scale values, marked on the scale lines, with the scale values increasing sequentially from top to bottom along the height direction of the glass sheet.
[0014] Optionally, the distance between two adjacent scale lines is 8.5 mm; the scale difference between two adjacent scale values is 50 mL.
[0015] Optionally, the number of vertical slots is 4 to 6, and the plurality of vertical slots are distributed on one side of the center line of the glass sheet along the width direction of the glass sheet.
[0016] Optionally, the distance between the vertical slot closest to the center line of the glass sheet and the center line of the glass sheet is in the range of 0.3 mm to 0.7 mm.
[0017] Optionally, the number of vertical slots is an even number from 8 to 12, and the plurality of vertical slots are symmetrically distributed on both sides of the center line of the glass sheet.
[0018] Optionally, the height of the glass sheet is greater than 50mm; the width of the glass sheet is between 77mm and 81mm; and the thickness of the glass sheet is between 5mm and 9mm.
[0019] Optionally, the height of each vertical slot ranges from 48mm to 52mm; the width of each vertical slot ranges from 4.3mm to 4.7mm; and the depth of each vertical slot ranges from 2.3mm to 2.7mm.
[0020] The grooved glass sheet provided in this disclosure can achieve the following technical effects:
[0021] This disclosure provides a grooved glass sheet, comprising a glass sheet with multiple vertical grooves along its height direction, uniformly distributed along its width direction, and all located on a single plane of the glass sheet. The vertical grooves are mechanically machined into the flat glass to create directional channels for bubble rise. The vertical grooves provide a directional flow path for the bubbles, causing small bubbles to merge into a continuous gas column along the grooves, significantly improving the visibility of trace amounts of gas. Even with very small amounts of gas, a clearly visible "gas line" can be formed within the grooves, greatly reducing the risk of missed detection of slowly generated gas and improving the reliability of light gas alarms. The grooves divide the glass into multiple load-bearing units, shortening the effective span and dispersing central bending stress. This effective stress dispersion improves the glass sheet's resistance to internal pressure changes (such as gas expansion and oil pressure impact), reducing the risk of oil leakage due to accidental breakage and enhancing equipment safety. Furthermore, the grooves act as pre-set stress release channels, absorbing some impact energy, and changing the fracture mode from radial bursting to localized groove fracture, reducing the risk of fragmentation.

[0038] Combination Figures 1 to 4 As shown, this embodiment of the disclosure provides a grooved glass sheet, comprising a glass sheet. The glass sheet includes a plurality of vertical grooves formed along its height direction, the plurality of vertical grooves being uniformly distributed along its width direction, and all located on a plane of the glass sheet.
[0039] This disclosure provides a grooved glass sheet with vertical grooves machined into a flat glass surface, creating a directional channel for rising bubbles. The vertical grooves provide a directional flow path for the bubbles, causing small bubbles to merge into a continuous gas column along the groove, significantly improving the visibility of trace amounts of gas. Even with very small amounts of gas, a clearly visible "gas line" can be formed within the groove, greatly reducing the risk of missed detection of slowly generated gas and improving the reliability of light gas alarms. The grooves divide the glass into multiple load-bearing units, shortening the effective span and dispersing central bending stress. This effective stress dispersion improves the glass sheet's resistance to internal pressure changes (such as gas expansion and oil pressure impact), reducing the risk of oil leakage due to accidental breakage and enhancing equipment safety.

This allows even a small amount of gas to form a clearly visible "gas line" within the slot, significantly reducing the risk of missed detection of slowly generated gas and improving the reliability of the light gas alarm.
