Description

Technical Field

[0001] The present invention relates to the technical field of box-type substations, and in particular to an intelligent box-type substation. Background Art

[0002] Box-type substation, also known as prefabricated substation or prefabricated substation, is a compact distribution equipment that integrates high-voltage switchgear, distribution transformers and low-voltage distribution devices according to a certain wiring scheme. It is a new type of substation that has emerged after civil substations. At present, box-type substations are widely used in mines, factories, enterprises, oil and gas fields, wind power stations and other places. It has gradually replaced the original civil distribution room or distribution station and has become a new type of complete set of transformation and distribution equipment.

[0003] Nowadays, with the rapid development of science and technology, in order to accurately monitor and allocate electricity, high-voltage switchgear and distribution equipment in box-type substations are developing in the direction of intelligence. With the increase in the intelligence level of power equipment in box-type substations, while facilitating the control of the power system, the heat dissipation pressure of power equipment is also greatly increased accordingly. The box-type substations in the prior art are mostly shells composed of a base, side panels, partitions, doors and top covers, etc., and are equipped with power equipment inside. Most of the power equipment adopts air cooling, and the power equipment in the box-type substation is cooled by the circulation of external gas from the outside to the inside. This heat dissipation method is easily affected by the surrounding environment and weather factors. In the case of high heat, the heat dissipation effect is not ideal, and when the temperature of the power equipment is too high or the humidity of the external gas is high, the service life of the power equipment will be reduced, and the transmission performance of the power will be reduced, and there are certain safety hazards.

[0015] The working principle and beneficial effects of the present invention are: 1. In the present invention, during installation, a pit is excavated in advance at the installation position, the underground box is placed in the pit, and the cables electrically connected to the power equipment are passed through the wiring tube 1 and the wiring tube 2 to the transformer box, and then the underground box is backfilled, and then the positioning motor is started, and the output end of the positioning motor drives the positioning worm to rotate, the positioning worm drives the positioning worm wheel to rotate, and the positioning worm wheel drives the positioning screw to rotate, so that the positioning ball nut group moves downward on the positioning screw, and the movement of the positioning ball nut group drives the hollow box door to move, so that the hollow box door is away from the transformer box, and then the existing intelligent power equipment is respectively installed on the transposition carrier, so that the intelligent power equipment and the cable are connected. Compared with the manual door-opening box substation with transmission, the electric drive is not only quick and convenient, but also has a high safety factor, and better realizes the sealing in the transformer box, reducing the risk of contact between the intelligent power equipment and the external gas; 2. In the present invention, after the intelligent power equipment is installed, the positioning motor is started again, and the intelligent power equipment in the transformer box is sealed by the movement of the positioning ball nut group to prevent impurities or moisture in the external gas from contacting the power equipment, so as to increase the service life of the power equipment; 3. In the present invention, when cooling the power equipment, the air circulation pump is started, and the air circulation pump will drive the gas in the equipment cavity into the air intake box along the air intake hole, and the gas in the air intake box will enter the hollow box door along the air intake duct, the air intake main pipe, the air circulation pump, the cooling main pipe, the cooling duct and the air outlet duct, and then be blown into the equipment cavity through the air outlet hole opened on the hollow box door, so as to move the gas in the equipment cavity. When the circulating gas passes through the cooling duct, the temperature of the gas will exchange heat with the cooling liquid in the cooling cavity, so as to cool the circulating gas, and the temperature of the cooling liquid will be conducted to the ground through the heat conduction pipe. In the actual heat conduction process, since the heat conduction effect of the soil layer is relatively poor, during the installation process, according to the height of the local groundwater level and the humidity of the ground, the length and thickness of the heat conduction pipe can be appropriately increased to cool the cooling liquid. Compared with the traditional air cooling, the internal circulation heat conduction method has a more rapid cooling effect. 4. In the present invention, the gas passing through the cooling duct will also pass through the dehumidification cotton in the dehumidification box to absorb and filter the moisture in the gas, ensuring that the cooling gas blown on the power equipment is dry cold air. In the process of cooling the power equipment, since not all power equipment generates heat during operation, in order to increase the flow rate of the gas passing through the heat-generating power equipment, the air outlet holes near the non-heat-generating power equipment on the hollow box door can be blocked, and only the air outlet holes near the heat-prone power equipment are retained. In the actual cooling process, in order to change the airflow path of the gas in the equipment cavity entering the air inlet hole through the air outlet hole, the air inlet hole can be started. Transposition motor, the output end of the transposition motor drives the transposition worm to rotate, the rotation of the transposition worm drives the transposition worm wheel to rotate, the rotation of the transposition worm wheel drives the transposition rotating rod connected thereto to rotate, and under the cooperation of the transposition sprocket set, the two transposition rotating rods rotate synchronously, and the rotation of the transposition rotating rod adjusts the angle of the transposition carrier plate, and the position of the power equipment on the transposition carrier plate is slightly moved through the movement of the transposition carrier plate, and when the transposition carrier plate is adjusted in angle, since the two transposition carrier plates are staggered, the line through which the gas flows is changed through the adjustment of the angle of the transposition carrier plate, so that the cooling gas can cool down more power equipment, and the cooling effect is more comprehensive; 5. Compared with the traditional box-type substation, the present invention not only has a strong sealing performance, which can effectively prevent the erosion of precision intelligent power equipment by dust and moisture in the outside air, but also has a high safety factor, which can effectively prevent damage by external non-staff members. At the same time, it has a good cooling effect and can effectively and intelligently and comprehensively cool the power equipment at different positions in the transformer box.

[0023] It should be noted that the present application is opened and closed by means of longitudinal sliding movement of the hollow box door 3, which not only has a high safety factor and prevents unintentional opening by irrelevant personnel, but also has good sealing performance and is more suitable for outdoor assembly.

[0024] As mentioned above, the air-circulating cooling mechanism 002 is arranged in the underground box 1, and the air-circulating cooling mechanism 002 is connected with the hollow box door 3 and the air inlet box 4. The air-circulating cooling mechanism 002 includes a cooling carrier plate 11, an air circulation pump 12 and a dehumidification component. The cooling carrier plate 11 is sealed and arranged in the underground box 1. The cooling carrier plate 11 divides the underground box 1 into a cooling cavity and a cargo cavity. The other end of the adjustment screw 6 is rotatably arranged on the cooling carrier plate 11, and the air circulation pump 12 is installed on the cooling carrier plate 11. An air inlet component is connected between the air inlet end of the air circulation pump 12 and the air inlet box 4, and an air outlet component is connected between the air outlet end of the air circulation pump 12 and the hollow box door 3.

[0027] Among them, the dehumidification component includes a dehumidification box 18 and a dehumidification box 19. The dehumidification box 18 is arranged on the cooling carrier 11. The dehumidification box 18 is connected to the air outlet duct 17. The dehumidification box 19 is detachably arranged in the dehumidification box 18. Dehumidification cotton 20 is placed in the dehumidification box 19. The dehumidification cotton 20 can be replaced by opening the dehumidification box 19.

[0028] Specifically, when cooling the power equipment, the air circulation pump 12 is started, and the air circulation pump 12 will draw the gas in the equipment cavity into the air intake box 4 along the air intake hole. The gas entering the air intake box 4 enters the hollow box door 3 along the air intake duct 13, the air intake main pipe 14, the air circulation pump 12, the cooling main pipe 15, the cooling duct 16 and the air outlet duct 17, and then is blown into the equipment cavity through the air outlet hole provided on the hollow box door 3 to move the gas in the equipment cavity. When the circulating gas passes through the cooling duct 16, the temperature of the gas will exchange heat with the cooling liquid in the cooling cavity to cool the circulating gas, and the temperature of the cooling liquid will be conducted to below the ground through the heat conduction pipe. In the actual heat conduction process, since the heat conduction effect of the soil layer is relatively poor, during the installation process, the length and thickness of the heat conduction pipe can be appropriately increased according to the height of the local groundwater level and the humidity of the ground, so as to cool the cooling liquid.

[0029] As mentioned above, the equipment installation mechanism 003 is arranged in the transformer box 2, and the equipment installation mechanism 003 is located in the equipment cavity and is used to carry the power equipment. The equipment installation mechanism 003 includes a transposition rotating rod 21, a transposition carrier plate 22, a transposition sprocket set 23, a conical transposition cover 24, a transposition worm 25, a transposition worm wheel 26 and a transposition motor 27. There are two transposition rotating rods 21, and the transposition rotating rods 21 are penetrated and rotatably arranged on the transformer box 2. There are two transposition carrier plates 22, and the transposition carrier plates 22 correspond to the transposition rotating rods 21 one by one. The transposition carrier plate 22 is arranged on the transposition rotating rod 21, and the two transposition carrier plates 22 are arranged in a staggered manner. The transposition sprocket set 23 is transmission-arranged between the two transposition rotating rods 21. The conical transposition cover 24 is arranged on the transformer box 2. The transposition worm 25 is rotationally arranged in the conical transposition cover 24. The transposition worm wheel 26 is arranged on one of the transposition rotating rods 21. The transposition worm wheel 26 is meshed with the transposition worm 25. The transposition motor 27 is installed on one side of the conical transposition cover 24, and the output end of the transposition motor 27 is connected to one end of the adjustment worm 9.

[0030] Specifically, in the process of cooling the power equipment, since not all power equipment generates heat during operation, in order to increase the flow rate of gas passing through the heat-generating power equipment, the air outlet holes near the non-heat-generating power equipment on the hollow box door 3 can be blocked, and only the air outlet holes near the heat-generating power equipment are retained. In the actual cooling process, in order to change the air flow path of the gas in the equipment cavity entering the air inlet holes through the air outlet holes, the transposition motor 27 can be started, and the output end of the transposition motor 27 drives the transposition worm 25 to rotate, and the rotation of the transposition worm 25 drives the transposition worm wheel 26 to rotate. The rotation of the transposition worm gear 26 drives the transposition rotating rod 21 connected thereto to rotate, and with the cooperation of the transposition sprocket set 23, the two transposition rotating rods 21 rotate synchronously, and the rotation of the transposition rotating rod 21 adjusts the angle of the transposition carrier plate 22. Through the movement of the transposition carrier plate 22, the position of the power equipment on the transposition carrier plate 22 moves slightly. When the transposition carrier plate 22 is adjusted in angle, since the two transposition carrier plates 22 are staggered, the line through which the gas flows is changed by adjusting the angle of the transposition carrier plate 22, so that the cooling gas can cool down more power equipment, and the cooling effect is more comprehensive.

[0031] It is additionally noted that a liquid infusion tube 29 is also provided on the cooling carrier plate 11 , and the liquid infusion tube 29 is connected to the cooling cavity. The liquid infusion tube 29 runs through the outside of the underground box 1 and is used to transport cooling liquid into the cooling cavity.

[0032] Both sides of the underground box 1 are connected with wiring tube 1 30, and multiple wiring tube 2 31 are connected between the underground box 1 and the transformer box 2. Through the cooperation of wiring tube 1 30 and wiring tube 2 31, the power equipment is electrically connected to the external cable. After the actual connection is completed, sealing foam can be filled in the wiring tube and the wiring tube 2 31 to prevent gas from flowing in the wiring tube 1 30 and the wiring tube 2 31.

[0033] It is further explained that, in the actual assembly process, it is necessary to pre-excavate an installation pit at the installation location, place the underground box 1 in the pit, and then backfill the underground box 1. In the actual installation process, the pre-buried depth of the underground box 1 can be adjusted according to the geographical location of the installation location. For example, in low-lying areas, in order to prevent rainwater from backflowing and causing flooding of smart power equipment, the pre-buried height of the underground box can be adjusted to raise the transformer box 2 above the ground. The water level in low-lying areas generally meets the cooling requirements of power equipment. Compared with traditional box-type substations, which use concrete pouring or overhead power poles, the installation method in this application is more flexible.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
