Description

Technical Field

[0001] The invention relates to the technical field of electric power, and in particular to an accident oil pool of a glass fiber reinforced plastic transformer substation. Background Art

[0002] Oil-containing electrical equipment occupies a mainstream position in power engineering equipment with high heat generation, such as transformers, capacitors, reactors, etc. above 10kV, due to its good insulation, heat dissipation and low cost.

[0003] The oil used in electrical equipment is flammable and is used in large quantities. For example, a transformer with a general voltage level of 35kV and a capacity of 20MVA uses about 8 tons of oil per unit. As the capacity increases, the amount of oil used increases exponentially. When a major failure occurs in oil-containing equipment, the oil in the equipment needs to be discharged in time and stored in a safe place to avoid ignition and expansion of the accident scale or secondary accidents. A better approach is to set up oil retaining facilities around oil-containing electrical equipment, and divert the oil to the accident oil pool for temporary storage, and hand it over to professional manufacturers for processing after the accident is handled.

[0004] Most of the existing accident oil pools are buried, with reinforced concrete structures, divided into two compartments, the oil storage chamber and the water storage chamber, which are connected by a connecting hole at the bottom, and the inlet and outlet pipes are at different heights. The difference in specific gravity between oil and water is used to discharge water after the accident oil enters. First, the oil storage volume does not decrease due to water in the oil pool, and second, oil and water separation is achieved to prevent transformer oil from flowing into the rainwater pipe network and causing pollution. The existing accident oil pool needs to be drained and people need to go down to clean the debris in the bottom sedimentation area, which is troublesome to maintain. In addition, the accident oil pool itself cannot be prefabricated, the on-site construction period is long, and the cost is high. For this reason, the Chinese utility model patent with application number CN201922357038.5 provides a glass fiber reinforced plastic accident oil pool, but after the accident oil is discharged into the accident oil pool, part of the accident oil will remain in the sand settling device and the first pipeline and cannot be discharged. The accident oil remaining in the sand settling device and the first pipeline will be discharged into the rainwater pipe network when it is used next time, causing pollution to the environment. Summary of the invention

The water storage tank 10 is located directly below the water outlet pipe 7, and the lower end of the water outlet pipe 7 extends into the water storage tank 10. In order to improve the structural strength of the tank body 1, the side wall of the tank body 1 can be designed to Figure 1 The corrugated structure shown in .

[0025] In the present invention, a plurality of lower baffles 24 parallel to each other are arranged between the mud guide plate 19 and the bottom surface of the tank body 1, the bottom of the lower baffle 24 is seamlessly connected to the bottom surface of the tank body 1, the front and rear ends of the lower baffle 24 are seamlessly connected to the tank body 1, a gap is arranged between the top of the lower baffle 24 and the mud guide plate 19, and the distance between the lower end of each lower baffle 24 and the bottom surface of the tank body 1 is equal.

[0026] In the present invention, the upper ends of all lower baffles 24 are located in the same plane, and the plane where the upper ends of all lower baffles 24 are located is parallel to the mud guide plate 19, thereby ensuring that the slow flow channel formed between the upper baffle and the lower baffle 24 has a sufficient length, thereby enabling the accident oil particles and mud to be fully separated from the rainwater. The distance between the lower baffle 24 and the adjacent upper baffle is at least 13 cm, thereby ensuring that the rainwater has a lower flow velocity when flowing in the channel between the upper baffle and the lower baffle 24, which is conducive to the floating of the accident oil particles and the sedimentation of the mud. .

[0027] In the present invention, a circular oil collecting hole 28 is formed at the upper end of the upper baffle plate, a linkage rod 21 is passed through the oil collecting hole 28, a first guide sleeve 20, a second guide sleeve 22 and an electromagnet 23 are installed on the bottom surface of the mud guide plate 19 from left to right, the first guide sleeve 20 and the second guide sleeve 22 are provided with through holes, the two ends of the linkage rod 21 are respectively passed through the through holes of the first guide sleeve 20 and the second guide sleeve 22 and can slide in the through holes of the first guide sleeve 20 and the second guide sleeve 22, a galvanized iron plate 34 is provided at one end of the linkage rod 21, and the corrosion of the iron plate is slowed down by galvanizing the surface of the iron plate, and the electromagnet 23 is arranged on the side of the galvanized iron plate 34 away from the second guide sleeve 22; a retaining ring 27 is provided on the linkage rod 21 on the side of the second guide sleeve 22 away from the galvanized iron plate 34, and the retaining ring 27 is connected to the first A compression spring 26 is arranged between the two guide sleeves 22, and the compression spring 26 may also preferably be made of corrosion-resistant materials to ensure that it has a long service life; a plurality of rubber plugs 29 are arranged on the rod body of the linkage rod 21, and when the electromagnet 23 is powered off, the plug 29 blocks the oil collecting hole 28 under the elastic force of the compression spring 26; the height of the lower end of the partition 18 is lower than the height of the upper end of the mud guide plate 19, and an oil storage area 32 is formed between the lower end of the partition 18 and the mud guide plate 19; an oil drain pipe 9 connected to the oil storage area 32 is arranged on the top of the mud guide plate 19, the top of the oil drain pipe 9 extends from the top of the tank body 1, and an oil drain pump 8 is arranged on the top of the oil drain pipe 9; a battery 2 and a switch for controlling the power on and off of the electromagnet 23 are also arranged on the top of the tank body 1, and the electromagnet 23 is electrically connected to the battery 2, and the battery 2 supplies power to the electromagnet 23.

[0028] In the present invention, a photoelectric switch 17 is arranged on the inner wall of the tank body 1 above the mud storage tank 14. The height of the photoelectric switch 17 is higher than the height of the lowest point of the mud guide plate 19. An alarm light 3 is arranged on the top of the tank body 1. The photoelectric switch 17 and the alarm light 3 are both electrically connected to the battery 2. The light-emitting state of the alarm light 3 is controlled by the photoelectric switch 17. The alarm light 3 is used to indicate that the interface between the oil layer and the water layer has reached the position of the photoelectric switch 17, so as to prevent the accident oil from flowing to the bottom of the mud guide plate 19. The height of the photoelectric switch 17 is higher than the height of the lowest point of the mud guide plate 19, which also provides sufficient reaction time for the staff. In order to further realize the intelligence of the device, a solenoid valve can be installed on the liquid inlet pipe 4. When the interface between the oil layer and the water layer reaches the position of the photoelectric switch 17, the photoelectric switch 17 controls the solenoid valve to close the liquid inlet pipe 4. In the specific implementation, the installation height of the photoelectric switch 17 can be 5 to 15 cm higher than the lowest point of the mud guide plate 19, and the warning light 3 can be either a two-color light or a single color. When the warning light 3 is a two-color light, the color of the warning light 3 can be changed to indicate that the interface between the oil layer and the water layer has dropped to the position of the photoelectric switch 17. When the warning light 3 is a single color, the light or dark of the warning light 3 can be used to indicate that the interface between the oil layer and the water layer has dropped to the position of the photoelectric switch 17. In addition to being powered by the battery 2, the electromagnet 23, the photoelectric switch 17 and the warning light 3 can also be connected to the mains after the voltage is reduced. It should be added that the photoelectric switch 17 and the electromagnet 23 should be waterproof when selecting.

[0029] Before using the present invention, clean water is first injected into the tank body 1, and the liquid level of the clean water is higher than the entire mud guide plate 19. After the clean water is injected into the tank body 1, the switch of the electromagnet 23 can be turned on, and the electromagnet 23 absorbs the galvanized iron plate 34 to further compress the compression spring 26, and the linkage rod 21 moves in the direction of the electromagnet 23, and the plug 29 is separated from the oil collecting hole 28. After that, the oil collecting hole 28 is in an open state, and the air in the angle between the upper baffle plate and the mud guide plate 19 moves upward along the mud guide plate 19 through the oil collecting hole 28 and gathers in the oil storage area 32 between the partition 18 and the mud guide plate 19, and then the oil discharge pump 8 is turned on to discharge the air in the oil storage area 32. When the present invention is in use, rainwater or oily sewage directly enters the tank body 1 from the liquid inlet pipe 4, and debris such as mud contained in the liquid will settle on the mud guide plate 19 and the mud storage tank 14. The debris settled on the mud guide plate 19 will slide down the mud guide plate 19 into the mud storage tank 14 under the action of gravity. After standing still in the tank body 1, the oil and water are separated, and the accident oil floats above the water layer; when the accident oil continues to be added to the tank body 1, the accident oil content in the tank body 1 gradually increases, and the water below the oil layer will be discharged from the outlet pipe 7. When adding accident oil or rainwater to the tank body 1, the water layer is in an unstable state under the disturbance of adding liquid, part of the accident oil has not yet floated into the oil layer, and part of the mud and sand particles have not settled on the mud guide plate 19. Therefore, the water layer will contain a small amount of accident oil particles and mud, and the water layer between the upper baffle plate 24 will exist Figure 2 According to the flow trend shown by the middle arrow, rainwater containing a small amount of accident oil particles and sediment will also enter the slow-flow channel formed between the upper baffle plate and the lower baffle plate 24. In the slow-flow channel between the upper baffle plate and the lower baffle plate 24, the accident oil particles float up, and the sediment sinks into the strip groove 30. Therefore, the rainwater entering the chamber on the right side of the partition 18 will contain very little or even no accident oil and sediment, thereby ensuring that the water discharged from the outlet pipe 7 is cleaner, and can effectively prevent the accident oil from flowing into the rainwater pipe network to avoid environmental pollution.

[0030] During use, when the interface between the oil layer and the water layer is located above the photoelectric switch, the receiving end of the photoelectric switch 17 can sense the light emitted by its transmitting end due to the good light transmittance of the water layer, and the alarm light 3 is in the green light state. When the interface between the oil layer and the water layer is located at the photoelectric switch 17, the receiving end of the photoelectric switch 17 will not be able to receive the light emitted by the transmitting end due to the obstruction of the oil layer, and then the photoelectric switch 17 controls the alarm light 3 to change to the red light state. The red light of the alarm light 3 indicates that the oil amount in the tank body 1 has reached the maximum value, and then a pipe can be inserted into the oil discharge port 6 to discharge the accident oil in the tank body 1.

[0031] After the present invention has been used for a period of time, mud and sand will be deposited in the mud storage tank 14 and the strip groove 30. The main mud discharge pump 15 and the auxiliary mud discharge pump 13 can be opened regularly to discharge the mud and sand deposited in the mud storage tank 14 or the strip groove 30. In addition, the electromagnet 23 can also be started regularly to make the accident oil floating in the corners of the upper baffle 25 and the mud guide plate 19 float to the oil storage area 32, and then the oil discharge pump 8 can be opened to discharge the accident oil in the oil storage area 32. The present invention is also very convenient for later maintenance.

[0032] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
