Description

Technical Field

[0001] This utility model relates to the field of auxiliary devices for power equipment, and in particular to a mounting bracket for a GIS gas density relay. Background Technology

[0002] Due to its small footprint, excellent insulation performance, and resistance to environmental interference, GIS has become a core device in high-voltage power systems and is widely used in urban substations and ultra-high-voltage direct current transmission. Its insulation and arc-extinguishing performance rely entirely on the internally sealed SF6 gas, and the gas density directly determines the safety of equipment operation. If the density is too low, it will cause serious accidents such as insulation breakdown and arc-extinguishing failure. Therefore, it is necessary to monitor the gas status in real time through density relays. The density relays need to use temperature compensation technology to distinguish between gas leakage and pressure fluctuations caused by temperature changes. When the density is abnormal, it triggers an alarm or lockout circuit, which is the safety guarantee of GIS equipment. However, due to the structural limitations of GIS equipment, high-voltage equipment is installed at high positions and the gas chambers are dispersed. The density relays often need to be led to a position that is easy to observe and operate through gas connecting pipes. This installation method directly creates a demand for special brackets.

[0003] Traditional gas connecting pipes lack dedicated insulation protection structures and are directly exposed around equipment, making them prone to insufficient safe distances from live components. This is especially problematic in humid or foggy environments, potentially causing flashover along the pipe and threatening the insulation safety of the power system. Existing brackets have added insulating sleeve components to completely encase the connecting pipe in a high-strength epoxy resin insulating sleeve, improving insulation performance. Insulating gaskets are also placed at the connection points to avoid potential difference issues caused by metal contact. However, the brackets have poor adaptability, and the connection between the brackets and GIS equipment mainly relies on welding and special bolt holes. When the equipment layout is adjusted on-site, the brackets cannot be adjusted to a fixed position, causing installation difficulties for users and failing to meet usage requirements. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a GIS gas density relay mounting bracket, which aims to improve the problem of low adaptability in the prior art and the inability to fix relays of different sizes.

[0007] As a further description of the above technical solution: The transmission assembly includes a worm gear, the middle part of which is fixedly connected to the middle part of the rotating column, and a worm is meshed with the outer wall of the worm gear.

[0008] As a further description of the above technical solution: The sliding assembly includes a rotating disk, the middle part of which is fixedly connected to the lower middle part of the outer wall of the rotating column, and the outer wall of the column is provided with a sliding groove.

[0009] As a further description of the above technical solution: The pushing component includes an inverted T-shaped column, the outer wall of which is slidably connected to the inner wall of a rectangular groove, and a pushing clamp is fixedly connected to the top of the inverted T-shaped column.

[0010] As a further description of the above technical solution: A fixing plate is fixedly connected to the left side of the motor, and the top of the fixing plate is fixedly connected to the bottom of the base plate. A gasket is fixedly connected to the inner wall of the push clamp.

[0011] As a further description of the above technical solution: The rebound assembly includes a spring, the bottom of which is fixedly connected to the top of the flip-up arc plate, and the top of which is fixedly connected to a fixing bracket.

The middle of the flip-up arc plate has an irregular opening, and a hollow knob is threadedly connected to the right side of the outer wall of the sliding column.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the worm gear driven by the motor drives the rotating disk to rotate.

The rectangular groove 205 at the top ensures the movement trajectory of the inverted T-shaped column 2081, pushing the clamp 2082 to gather from all sides towards the center, clamping the relay body 209 in the center to achieve a fixed effect. This structure can fix relay bodies 209 of different sizes and specifications, improving equipment adaptability. Springs 3041 on the front and rear sides of the bottom of the base plate 1 open the two flip-up arc plates 303. The flip-up arc plates 303 rotate by the pivot 302. The pipe is placed in the middle of the flip-up arc plates 303 and pushed upwards, so that the front and rear sides clamp and wrap around it. When the pipe is wrapped, the sliding column 3051 is inserted into the irregular opening 3052. The flat head of the front side of the sliding column 3051 passes through the flip-up arc plate 303 and rotates 90 degrees to prevent it from retracting. The rear side is fixed by tightening the hollow knob 3053. This installation method is fast, convenient and firm, which improves efficiency.
