Description

Technical Field

[0001] This utility model relates to the field of fuse technology, specifically a 10kV drop-out fuse with a fireproof fuse wire. Background Technology

[0002] The construction of power grids is itself an important infrastructure project that can drive the development of related industries, such as power equipment manufacturing, wire and cable production, and engineering construction. At the same time, a well-developed power grid also supports the construction of other infrastructure, such as urban rail transit and communication base stations, which all rely on a stable power supply to operate normally. Xilin Gol League in Inner Mongolia is a grassland region. Due to the fast pace of modern life, the construction of power grids has enabled electricity access for every household, greatly facilitating the lives of the people.

[0003] However, the laying of power grids on grasslands has also brought some safety hazards, such as grassland fires caused by line faults. In the actual operation of 10kV distribution lines, the melting metal of drop-out fuses can cause varying degrees of burning of weeds and other materials below. Although no fire accidents have occurred, these have become fire hazards. Currently, the weeds and debris under the drop-out fuses of the distribution lines are cleared in a planned manner according to the season and plant growth. As the grass grows, the number of clearings also increases, resulting in a large workload for fire prevention and high line maintenance costs. Therefore, this method does not meet the current needs, and a fireproof 10kV drop-out fuse is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a fireproof fuse for a 10kV drop-out fuse. The fuse is installed inside a ceramic fixing tube filled with quartz sand. Both ends of the fixing tube are sealed. Both ends of the fuse are connected to an electrical wire, with the other end of the wire extending through the sealing tube to the outside, thus forming a fireproof fuse assembly. Finally, the fireproof fuse assembly is installed inside the drop-out fuse. When the fuse melts, the high-temperature liquid metal is trapped inside the fixing tube, preventing the molten metal from splashing onto weeds and causing a fire. This solves the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a 10kV drop-out fuse fireproof fuse wire, including a fireproof fuse assembly and a drop-out fuse tube. The fireproof fuse assembly is located inside the drop-out fuse tube. The fireproof fuse assembly includes a fixing tube, a filling layer, a fuse wire, terminals, sealing plugs, and wires. The fixing tube is made of ceramic material, the filling layer is made of quartz sand material, and the sealing plugs are made of silicone material. At least two sealing plugs are provided, with the two sealing plugs located at both ends of the fixing tube, the two terminals located at both ends of the fuse wire, and the two wires connected to both ends of the fuse wire through the terminals.

[0006] Preferably, the fixing tube and the two sealing plugs form a cylindrical closed space, the filling layer is located inside the cylindrical closed space, and the fuse, terminal and one end of the wire are all located inside the filling layer.

[0007] Preferably, the sealing plug includes a positioning ring, a connecting rod, a plug, and a through hole, with the positioning ring and the plug connected by the connecting rod.

[0008] Preferably, the plug has a disc-shaped structure, the diameter of the plug is larger than the outer diameter of the fixed pipe, and the outer diameter of the positioning ring is interference-fitted with the inner diameter of the fixed pipe.

[0009] Preferably, the positioning ring is a trumpet-shaped structure with a wide opening at one end and a narrow opening at the other end, and the wide end of the positioning ring is fitted to the inner wall of the fixing tube.

[0010] Preferably, the through hole passes through the positioning ring, the connecting rod and the plug in sequence, and one end of the wire extends through the through hole into the interior of the fixing tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model involves installing a fuse inside a ceramic fixing tube filled with quartz sand. Both ends of the fixing tube are sealed. The two ends of the fuse are connected to two wires via terminals, and the other end of the wires extends through the sealing block to the outside of the fixing tube, thus forming a fusible fireproof assembly. Finally, personnel install the fusible fireproof assembly inside a drop-out fuse. When the fuse is triggered, the fuse begins to melt, and the liquid high-temperature metal is trapped inside the fixing tube, preventing the molten metal from splashing onto weeds and causing a fire. This solves the problem of personnel needing to frequently clear the weeds below the fuse and reduces the labor intensity of personnel.

[0013] 2. This utility model uses two sealing plugs to seal both ends of the fixed pipe, forming a closed space with the fixed pipe and the two sealing plugs. The quartz sand filling layer and the fused wire are located inside the closed space. The filling layer mainly serves to insulate and cool. After the fused wire melts, the heat in the liquid high-temperature metal is absorbed by the filling layer, causing the liquid high-temperature metal and the filling layer to mix and gradually re-solidify. This traps the molten metal inside the fixed pipe, thereby reducing the probability of fire and lowering the maintenance costs of the power grid in grassland areas. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To address the issues of high workload for fire prevention and high line maintenance costs, please refer to [link / reference needed]. Figure 1-4 This utility model provides an embodiment of a 10kV drop-out fuse fireproof fuse wire, including a fireproof fuse assembly 1 and a drop-out fuse tube 2. The fireproof fuse assembly 1 is located inside the drop-out fuse tube 2. The fireproof fuse assembly 1 includes a fixing tube 101, a filling layer 102, a fuse wire 103, a terminal 104, a sealing plug 105, and wires 3. The fixing tube 101 is made of ceramic material, the filling layer 102 is made of quartz sand material, and the sealing plug 105 is made of silicone material. At least two sealing plugs 105 are provided, with the two sealing plugs 105 located at both ends of the fixing tube 101, and the two terminals 104 located at both ends of the fuse wire 103. The two wires 3 are connected to both ends of the fuse wire 103 through the terminals 104.

[0021] The sealing plug 105 includes a positioning ring 1051, a connecting rod 1052, a plug 1053, and a through hole 1054. The positioning ring 1051 and the plug 1053 are connected by the connecting rod 1052. The plug 1053 has a disc-shaped structure and its diameter is larger than the outer diameter of the fixed tube 101. The outer diameter of the positioning ring 1051 is interference-fitted with the inner diameter of the fixed tube 101. The positioning ring 1051 has a trumpet-shaped structure with one end wide and the other end narrow. The wide end of the positioning ring 1051 fits against the inner wall of the fixed tube 101. The through hole 1054 passes through the positioning ring 1051, the connecting rod 1052, and the plug 1053 in sequence. One end of the wire 3 passes through the through hole 1054 and extends into the interior of the fixed tube 101.

[0022] After the personnel install the fireproof fuse component 1 inside the drop-out fuse tube 2, when the fuse triggers the fuse wire 103 to start melting, the liquid high-temperature metal is trapped inside the fixed tube 101, which avoids the situation where the molten metal splashes onto the weeds and causes a fire. This solves the problem that personnel need to frequently clear the weeds under the fuse and reduces the labor intensity of personnel.

[0023] The fixed pipe 101 and two sealing plugs 105 form a cylindrical enclosed space. The filling layer 102 is located inside the cylindrical enclosed space. The fuse 103, terminal 104, and one end of the wire 3 are all located inside the filling layer 102. The filling layer 102 mainly serves to insulate and cool. After the fuse 103 melts, the heat in the liquid high-temperature metal is absorbed by the filling layer 102, causing the liquid high-temperature metal and the filling layer 102 to mix and gradually re-solidify. This traps the molten metal inside the fixed pipe 101, thereby reducing the probability of fire, reducing the maintenance costs of the power grid in grassland areas, and further protecting the grassland ecosystem.

[0024] Working principle: After the personnel install the fireproof fuse component 1 inside the drop-out fuse tube 2, when the fuse triggers the fuse wire 103 to start melting, the liquid high-temperature metal is trapped inside the fixed tube 101, which avoids the situation where the molten metal splashes onto the weeds and causes a fire. This solves the drawback of personnel having to frequently clear the weeds under the fuse, reduces the labor intensity of personnel, and reduces the maintenance cost of the power grid in grassland areas.
