Technical Field
[0001] The present invention relates to the technical field of transformer substations, in particular to an automatic energy storage pre-installed box transformer substation. Background Art
[0002] Prefabricated box substation is also called combined substation, or box transformer for short. It is a factory-prefabricated indoor and outdoor compact distribution equipment that integrates high-voltage switchgear, distribution transformer and low-voltage distribution device according to the corresponding wiring method. Due to its advantages of low loss, short power transmission cycle, flexible site selection, low radiation, convenient installation and use, and easy maintenance, it has gradually become an important power equipment widely used in the construction and transformation of the national power grid. However, since the transformer and high-voltage equipment are installed in the same metal shell box, it puts forward high requirements for the heat dissipation of the transformer. When the transformer is running, it will continuously generate a lot of heat, causing the indoor temperature to rise continuously. Especially when the ambient temperature is high, it is more likely to cause heat dissipation difficulties, which in turn affects the output. If the temperature is not reduced in time, the electrical equipment will not be able to operate normally. In mild cases, the power system will be paralyzed, and in severe cases, it will cause fires and cause greater harm. In addition, in warm and cold areas, too low temperature will also have an adverse effect on the normal operation of the equipment. Therefore, the equipment works in a certain temperature range, which can not only make the equipment operate normally, reduce the frequency of equipment maintenance, but also increase the service life of the equipment.

[0020] As attached Figure 2 As shown, the atomizing nozzle 17 includes an air inlet pipe 22, a valve core 23, a fairing 30, a connecting seat 24, a valve body 25 and a valve core assembly, wherein the air inlet pipe 22 has an air inlet hole 32 in the center and a liquid inlet hole 31 is arranged on the side wall, wherein the valve core 23 has a through hole 2 in the center, wherein the structure of the right end part of the through hole 2 is composed of conical sections at both ends and a cylindrical section in the middle, wherein the aperture of the through hole of the cylindrical section part is smaller than the aperture of the through hole of the left end part of the through hole 2, an external thread is arranged on the left end of the valve core 23, the left end thread is installed in the air inlet pipe 22 and a sealing ring is arranged between the valve core 23 and the air inlet pipe 22 for sealing, a liquid inlet hole 23 is arranged on the right end part of the through hole 2, and the liquid inlet hole 233 is located at the right end cylindrical section part of the through hole 2, and the air inlet hole 32 of the air inlet pipe 22 and the through hole 2 of the valve core 23 form a gas channel. The left end of the fairing 30 is threadedly connected to the outer ring of the intake pipe 22, and the left end of the fairing 30 contacts the right end surface of the valve core 1 23 and the right end surface of the intake pipe 22, and a sealing device is arranged between the valve core 1 23 and the right end of the intake pipe 22, the liquid inlet hole 1 31 is connected to the outlet joint 34 of the connecting seat 24, the connecting seat 24 is connected to the valve body 25 and forms an internal chamber, and the valve core assembly and the spring 27 are arranged in the internal chamber from top to bottom, the valve core assembly includes a rubber sealing pad 36 arranged at the upper end of the valve core 26, a reed 29 is also fixedly arranged on the valve core 26, and a liquid inlet hole 3 44 is also arranged at the lower end of the valve core 26, and the spring 27 is arranged between the lower end of the valve core 26 and the valve body 25. A coil 28 is arranged on the valve body 25 at both sides of the spring 27, and an armature 43 is arranged on the lower end of the valve core 26 at both sides of the spring 27. An inlet joint 35 is arranged at the lower part of the valve body 25, and the inlet joint 35 is connected to the water pump in the cavity 7 through a water pipe. When the coil 28 is not energized, the reed 29 remains in a free state, and the spring 27 pushes the valve core 26 to seal the liquid inlet hole 1 31 through the rubber sealing gasket 36. When the coil 28 is energized, the valve core 26 moves downward under the electromagnetic attraction to open the liquid inlet hole 1 31, thereby realizing the supply of cooling water. The liquid inlet hole 1 31 and the gap between the valve core 1 23 and the intake pipe 22 and the liquid inlet hole 2 33 of the valve core 1 23 constitute a cooling water channel.
[0021] At the same time, a flow channel 37 connected to the through hole at the right end of the valve core 23 is arranged at the left end of the fairing 30. The flow channel 37 has a conical section and a cylindrical section. The conical section is consistent in shape and size with the conical section at the right end of the through hole 2. A sawtooth 38 is arranged on the inner surface of the cylindrical section. The inclination angle of the longitudinal section of the sawtooth is 7-11 degrees, and the length of the sawtooth is 3-4.6mm. After the high-pressure gas enters from the air inlet 32, the cooling water merges with the high-speed airflow at the outlet of the liquid inlet hole 2 33 of the valve core 23. The cooling water is impacted and broken to be atomized to form large droplets. Then the large droplet group continues to enter the flow channel 37 with the high-speed jet. The sawtooth 38 can aggravate the instability of the two-phase fluid in the flow channel 37, further strengthen the fluctuation of the fluid in the flow channel 37, so that cracking occurs again. Atomized into small droplets, in addition, a blade chamber 39 connected to the flow channel 37 is arranged at the right end of the fairing 30, a servo motor 40 is arranged at a position in the right side wall of the blade chamber 39, and a spiral blade 41 is arranged at the output end of the servo motor 40, the spiral blade 41 faces the outlet of the flow channel 37, and a plurality of nozzles 42 are evenly distributed around the servo motor 40 on the right side wall of the blade chamber 39. The small droplets from the flow channel 37 undergo centrifugal motion when passing through the spiral blade 41, and are atomized again under the action of the centrifugal force, so that the droplet distribution is more uniform, the high-speed rotating spiral blade makes the droplet group more uniform when spraying, and it is also more balanced when cooling the metal box 1, thereby improving the cooling efficiency and providing a suitable working environment for the electrical equipment.
[0022] The solenoid valve 1 9, the solenoid valve 2 18, the solenoid valve 3 15, the heater 12, the refrigerator 21, the liquid level sensor 14, the liquid level sensor 2 16, the servo motor 1 6, the servo motor 2 40, the electric telescopic rod, the temperature sensor, the coil 28, the high-pressure air pump 19, the water pump, the infrared transmitter and the infrared receiver are all connected to the PLC controller signal.
[0023] When the PLC controller receives the detection result of the temperature sensor set in the metal box 1, it will automatically determine whether the temperature inside the box is within the preset threshold range. If the temperature inside the box is higher than the threshold range, the refrigerator 21 is started to cool the water in the cavity 7 of the cooling water tank 5, and the coil 28 is energized while the water pump is started to supply cooling water to the cooling water channel, and the high-pressure air pump 19 is started at the same time to supply high-pressure airflow to the gas channel, and the cooling water is atomized three times and then sprayed out through the nozzle 42 to evenly cool the box until the temperature inside the box is within the preset threshold range, and then the cooling work is stopped; if the temperature inside the box is lower than the threshold range, the heater 12 is started to heat the water in the left chamber 10 and dissipate heat through the heat sink 13 to raise the temperature inside the box. High, until the temperature inside the box is within the preset threshold range, then the heating work is stopped; in addition, when the water volume in the cavity 7 of the cooling water tank 5 is insufficient, the liquid level sensor 2 16 transmits a signal to the PLC controller, and the PLC controller starts the servo motor 1 6 to drive the cooling water tank 5 to move along the annular guide rail 8, and turns on the infrared transmitter and the infrared receiver at the same time. After the infrared receiver receives the signal, the PLC controller determines that the positions of the water outlet and the water inlet are in an aligned state at this time, and then turns off the servo motor 1 6, and opens the solenoid valve 1 9 and the solenoid valve 3 15 to release water into the cavity 7, until the liquid level sensor 2 16 sends a liquid level signal back to the PLC controller, and after monitoring that the liquid level in the cavity 7 has reached the preset liquid level value, the solenoid valve 1 9 and the solenoid valve 3 15 are closed, thereby completing the automatic water replenishment of the cooling water tank. In addition, when the water level in the left chamber 10 is insufficient, the liquid level sensor 14 transmits a signal to the PLC controller, and the PLC controller opens the solenoid valve 19 and the solenoid valve 2 18 to release water into the left chamber 10 until the liquid level sensor 14 returns a liquid level signal to the PLC controller. After monitoring that the liquid level in the left chamber 10 has reached a predetermined liquid level value, the solenoid valve 19 and the solenoid valve 2 18 are closed, thereby completing the automatic water replenishment of the left chamber 10.
[0024] Through the application of the above-mentioned equipment, the temperature inside the substation can be automatically controlled, and the temperature inside the box can be maintained within the preset threshold range. It can adapt to working environments with different climates and can greatly reduce the frequency of equipment maintenance, thereby increasing the service life of the equipment and reducing operating costs.
[0025] The above description is only a preferred specific implementation manner of the present invention, but the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
