Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to primary equipment of an electric power engineering substation. Background Art

[0002] The primary equipment in a power substation primarily includes transformers, high-voltage switchgear, current transformers, and voltage transformers. These devices are responsible for the transmission and distribution of electrical energy and are essential components of the substation. For example, transformers convert high and low voltages, high-voltage switchgear controls and protects the power system, and current and voltage transformers are crucial components for measuring current and voltage.

[0003] The history of the fireproof transformer dates back to the early days of the electrical age, in the late 19th century. In 1881, Lucien Golar and John Dixon Gibbs demonstrated a device called a "secondary hand generator" in London. This technology was then sold to Westinghouse Electric Company in the United States. This device may be one of the earliest transformers. Transformers are key devices for the transmission and distribution of electricity, regulating the flow of electrical energy from power plants to end users by changing the voltage. A fireproof transformer is a type of transformer designed with fire safety in mind. In the early days, strict safety standards for power systems and equipment were not yet in place, and fire accidents were common. To improve the safety and reliability of power systems, the development of fireproof transformers began.

[0004] The prior art proposes a Chinese patent with publication number CN221431975U to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a transformer fire prevention device, comprising a transformer box, a vacuum box, a diaphragm, a push-pull rod, a reciprocating structure, a vacuum pipe, an air jet pipe, a one-way conveying structure, an electric push rod, and a sealing cover. The transformer box is provided with a vacuum box above the outside, a diaphragm is provided inside the vacuum box, a push-pull rod is provided on the front side of the diaphragm, a reciprocating structure is provided between the push-pull rod and the vacuum box, an air jet pipe and a vacuum pipe are provided above and below the vacuum box, and a one-way conveying structure is provided inside the vacuum pipe and the air jet pipe. The transformer box is provided with an electric push rod inside, and a sealing cover is provided on the lower side of the electric push rod. Compared with the prior art, the advantages of this utility model are: preventing re-ignition; and being able to quickly exhaust smoke and dust. However, there is still a problem that the transformer cannot be kept under constant attention and fire extinguishing cannot be carried out immediately when a fire occurs, which may cause the fire to spread and increase losses. Utility Model Content

[0005] The purpose of the present utility model is to provide a primary device for a power engineering substation to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A primary device for a power substation includes a housing, a fire extinguishing mechanism, and a transformer. The housing has a recess for accommodating the transformer. The transformer is fixedly mounted within the housing. The fire extinguishing mechanism includes a fire extinguishing tank, a sensing component, a triggering component, a driving component, and a sealing component. The triggering component is fixedly mounted within the fire extinguishing tank. One end of the triggering component is fixedly connected to the sensing component, and the other end is fixedly connected to the driving component. The sealing component is rotatably connected to the driving component.

[0008] Using the above technical solution, when the transformer inside the housing catches fire, the sensing component senses the rising external temperature, pushing the trigger component upward to release the push component, which then squeezes the fire-extinguishing gas stored in the fire extinguisher tank. This push component simultaneously squeezes the gas and drives the sealing component, which seals the housing and allows the fire-extinguishing gas to fill the entire housing. Through the coordination of these components, the housing can be immediately sealed and gas can be ejected to extinguish the fire after the transformer catches fire, significantly reducing the damage caused by the fire.

[0009] A further improvement of the technical solution of the present utility model is that the trigger assembly includes a limit rod, multiple movable blocks, multiple rotating shafts, and multiple arc blocks. The multiple arc blocks are fixedly mounted on the limit rod in a circular array. The rotating shaft is rotatably connected to the arc blocks. The movable blocks are fixedly connected to the rotating shaft.

[0010] A further improvement of the technical solution of the present utility model is that the trigger assembly further includes a plurality of gears and a plurality of racks. The gears are fixedly connected to the rotating shaft. The plurality of racks are fixedly mounted in a circular array on the limit rod. The gears mesh with the racks.

[0011] With the above technical solution, when the limit rod moves upward, the rack moves accordingly, driving the meshing gear to rotate, causing the shaft to drive the movable block to follow the movement until the movable block stands up and fits the arc block. When the limit rod is stationary, the movable block and the limit rod are at a 0-degree perpendicular position.

[0012] A further improvement of the technical solution of the present utility model is that the sensing assembly includes a container tube and a piston. The piston is slidably connected to the container tube. The piston is fixedly connected to a limit rod. Mercury is placed in the container tube.

[0013] With the above technical solution, when a fire breaks out and the temperature rises, the mercury stored in the container tube boils, and the generated gas pressure squeezes piston one, causing piston one to push the limit rod upward. This provides power to the trigger assembly as soon as the fire breaks out.

[0014] A further improvement of the technical solution of the present utility model is that the pushing assembly includes a stopper, a spring, and a second piston. The stopper defines a first groove for movably connecting to a stopper rod. The stopper is fixedly mounted within the fire extinguisher tank. One end of the spring is fixedly connected to the stopper, and the other end is fixedly connected to the second piston.

[0015] With the above technical solution, when the limit rod moves upward, the spring releases elastic potential energy, pushing the second piston upward to squeeze the fire extinguishing gas, causing the fire extinguishing gas to be ejected, thereby achieving the fire extinguishing function.

[0016] A further improvement to the technical solution of this utility model is that the sealing assembly includes a connecting block, a sealing plate, and two L-shaped grooves. A second groove is provided on one side of the fire extinguisher tank, which is slidably connected to the connecting block. One end of the connecting block is movably connected to the push assembly, while the other end engages the sealing plate. The two L-shaped grooves are provided in the housing. The sealing plates slide within the L-shaped grooves.

[0017] The above-mentioned technical solution is adopted. In this solution, when the piston 2 moves upward, the connecting block is driven to rise through the groove 2. The other end of the sealing plate is pressed against the sealing plate and pushes the sealing plate to move and fall in the "L-shaped groove" under the action of friction, thereby sealing the outer shell, preventing the fire extinguishing gas from escaping and the flame from spreading, and thus improving the efficiency of fire extinguishing.

[0018] A further improvement of the technical solution of the utility model is that: a plurality of heat dissipation holes are provided on both sides of the shell.

[0019] By adopting the above technical solution, the heat dissipation holes in the solution can be of any shape, which satisfies the function of heat dissipation during daily transformer operation.

[0020] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0021] 1. The utility model provides a primary equipment of a power engineering substation. When the transformer in the outer shell catches fire due to various factors, the temperature rises, the mercury stored in the container tube boils, and the generated air pressure squeezes piston one, causing piston one to push the limit rod upward. The rack moves accordingly, driving the meshing gear to rotate, causing the rotating shaft to drive the movable block to follow the movement until the movable block stands up and fits the arc block, allowing the limit rod to pass through groove one. The restriction on the pushing component is then released. The spring releases elastic potential energy, pushing piston two upward to squeeze the fire extinguishing gas stored in the fire extinguishing tank, causing the fire extinguishing gas to be ejected to extinguish the fire. This prevents manual fire extinguishing after the fire is discovered, which wastes time, and enables the fire to be extinguished as soon as the transformer catches fire, thereby gaining precious fire extinguishing time and preventing the fire from getting bigger.

[0022] 2. The utility model provides a primary equipment of a power engineering substation. When the second piston moves upward, the connecting block is driven to rise through the second groove. The other end of the sealing plate is pressed against the sealing plate and pushes the sealing plate to move and fall in the "L-shaped groove" under the action of friction, thereby sealing the outer shell. Through the cooperation between the above components, the outer shell is sealed in the first time to prevent the spread of fire, thereby greatly reducing various losses caused by fire.

[0032] The present invention is further described in detail below with reference to the embodiments:

[0033] Example 1

[0034] like Figure 1-Figure 7 As shown, the present invention provides primary equipment for a power substation, including an enclosure 1, a fire extinguishing mechanism 2, and a transformer 9. The transformer 9 is fixedly mounted within the enclosure 1. The fire extinguishing mechanism 2 is fixedly mounted within the enclosure 1. The fire extinguishing mechanism 2 includes a fire extinguishing tank 3, a sensing assembly 4, a trigger assembly 5, a push assembly 6, and a sealing assembly 7. The trigger assembly 5 is fixedly mounted within the fire extinguishing tank 3. One end of the trigger assembly 5 is fixedly connected to the sensing assembly 4, and the other end is fixedly connected to the push assembly 6. The sealing assembly 7 is rotatably connected to the push assembly 6.

[0035] In this embodiment, when transformer 9 within housing 1 catches fire, sensing component 4 detects the rising external temperature, pushing trigger component 5 upward to release push component 6, which in turn squeezes the fire-extinguishing gas stored in fire extinguisher tank 3 and ejects it. This squeeze of gas simultaneously drives sealing component 7, which seals housing 1 and allows the fire-extinguishing gas to fill the entire housing 1. The coordination of these components allows housing 1 to be immediately sealed and gas ejected to extinguish the fire immediately after transformer 9 catches fire, significantly reducing the damage caused by the fire.

[0036] like Figure 1-Figure 7 As shown, in this embodiment, the trigger assembly 5 preferably includes a limit rod 51, multiple movable blocks 52, multiple rotating shafts 53, and multiple arc blocks 56. The multiple arc blocks 56 are fixedly mounted in a circular array on the limit rod 51. The rotating shaft 53 is rotatably connected to the arc blocks 56. The movable block 52 is fixedly connected to the rotating shaft 53. The movable block 52 is rectangular, spaced one end from the limit rod 51, and can rotate with the rotating shaft 53.

[0037] like Figure 1-Figure 7 As shown, the trigger assembly 5 preferably further includes a plurality of gears 54 and a plurality of racks 55. The gears 54 are fixedly connected to the rotating shaft 53. The racks 55 are fixedly mounted in a circular array on the limiting rod 51. The gears 54 mesh with the racks 55. When the limiting rod 51 moves upward, the racks 55 move accordingly, driving the meshed gears 54 to rotate, causing the rotating shaft 53 to drive the movable block 52 to follow the movement until the movable block 52 stands upright and abuts the arc block 56. When the limiting rod 51 is stationary, the movable block 52 is perpendicular to the limiting rod 51 at a 90-degree angle.

[0038] like Figure 1-Figure 7 As shown, the sensing assembly 4 preferably includes a container tube 41 and a piston 42. The piston 42 is slidably connected to the container tube 41. The piston 42 is fixedly connected to a limit rod 51. Mercury is placed in the container tube 41. When an external fire occurs and the temperature rises, the mercury stored in the container tube 41 boils, and the generated gas pressure squeezes the piston 42, causing it to push the limit rod 51 upward. This provides power to the trigger assembly 5 immediately upon the occurrence of a fire.

[0039] like Figure 1-Figure 7 As shown, the push assembly 6 preferably includes a stopper 61, a spring 62, and a second piston 63. The stopper 61 defines a first groove for movably connecting to the stopper rod 51. The stopper 61 is fixedly mounted within the fire extinguisher tank 3. One end of the spring 62 is fixedly connected to the stopper 61, and the other end is fixedly connected to the second piston 63. When the stopper rod 51 moves upward, the spring 62 releases its elastic potential energy, pushing the second piston 63 upward to squeeze the fire extinguishing gas, causing it to be ejected, achieving the fire extinguishing function.

[0040] like Figure 1-Figure 7As shown, preferably, the sealing assembly 7 includes a connecting block 71, a sealing plate 72, and two "L-shaped grooves" 73. A groove 2 is provided on one side of the fire extinguishing tank 3, which is slidably connected to the connecting block 71. One end of the connecting block 71 is movably connected to the pushing assembly 6, and the other end is fitted with the sealing plate 72. Two "L-shaped grooves" 73 are provided in the outer shell 1. The sealing plate 72 is slidably connected in the "L-shaped groove" 73. While the piston 2 63 moves upward, the connecting block 71 is driven to rise through the groove 2, and the other end fitted with the sealing plate 72 pushes the sealing plate 72 to move and fall in the "L-shaped groove" 73 under the action of friction, thereby sealing the outer shell 1, preventing the fire extinguishing gas from dissipating and the flame from spreading, and thus improving the efficiency of fire extinguishing.

[0041] like Figure 1-Figure 7 As shown, preferably, a plurality of heat dissipation holes 8 are provided on both sides of the housing 1. The heat dissipation holes 8 can be of any shape, and are sufficient to achieve the function of heat dissipation when the transformer 9 is working in daily operation.

[0042] The following is a detailed description of the working principle of the primary equipment of the power engineering substation.

[0043] like Figure 1-Figure 7 As shown, when transformer 9 within housing 1 catches fire due to various factors, the temperature rises, causing the mercury stored in container tube 41 to boil. The generated gas pressure squeezes piston 1 42, causing it to push limit rod 51 upward. Rack 55 then moves, driving meshing gear 54 to rotate. This causes shaft 53 to drive movable block 52 with it, until movable block 52 rises and abuts against arc block 56, allowing limit rod 51 to pass through groove 1. This releases the restraint on push assembly 6. The spring 62 releases elastic potential energy, pushing the second piston 63 to rise and squeeze the fire extinguishing gas stored in the fire extinguishing tank 3, so that the fire extinguishing gas is ejected. While the second piston 63 moves upward, it drives the connecting block 71 to rise through the second groove, and the other end of the sealing plate 72 is pressed against the sealing plate 72 and pushes the sealing plate 72 to move and fall in the "L-shaped groove 73" under the action of friction, thereby achieving sealing of the outer shell 1. Through the cooperation between the above-mentioned components, the fire extinguishing gas is ejected to extinguish the fire while the outer shell 1 is closed, preventing the need for manual fire extinguishing after the fire is discovered, which wastes time. The fire can be extinguished as soon as the transformer 9 catches fire, winning precious fire extinguishing time, preventing the spread of fire, and greatly reducing various losses caused by the fire.

[0044] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
