Description

Technical Field

[0001] The invention belongs to the technical field of ring main unit gas boxes, and in particular relates to a ring main unit gas box with high safety performance. Background Art

[0002] The ring main unit gas box is a high-voltage electrical equipment, also known as SF6 gas-insulated metal-enclosed switchgear. Its main body is made of high-quality stainless steel and is spliced ​​and formed with the help of advanced laser welding technology. After welding, it undergoes strict penetration testing and radiographic testing processes to ensure that the box welds are tight and free of any cracks, pores and other defects, to ensure airtightness, and the annual leakage rate is controlled at an extremely low level. The double-layer compartment structure is carefully planned internally, and the exclusive spaces such as the busbar room, circuit breaker room, and cable room are clearly divided. Each compartment is separated by a special nano-composite insulating material partition, which has a precisely controlled dielectric constant and an extremely low dielectric loss tangent value, thereby optimizing the electric field distribution, building a strong insulation defense line, and effectively avoiding creepage and flashover hazards. Even if it is subjected to a high voltage of 35 kV for a long time, it can ensure that the electrical insulation is foolproof. After completion, the overall insulation test and withstand voltage test are strictly carried out to ensure the quality of the equipment. When used outdoors, multiple ring main unit gas boxes are concentrated together and protected by a protective box. However, since multiple ring main unit gas boxes are installed together, a large amount of heat will be generated when they are running at the same time. Although multiple heat dissipation holes are set on the outer surface of the protective box, the heat dissipation effect is certain, and the internal temperature cannot be monitored, and the heat dissipation effect cannot be adjusted according to the actual internal temperature.

The side shell is provided with a plurality of first heat dissipation holes 23, and a heat dissipation fan 24 electrically connected to the control board 14 is installed on the side of the box body 1 opposite to the plurality of first heat dissipation holes 23. A smoke alarm 25 and a temperature sensor 26 electrically connected to the control board 14 are provided on the upper inner wall of the placement cavity 11, and a placement groove 27 surrounding the control cabinet 12 is provided on the lower inner wall of the placement cavity 11. A fireproof cloth 28 folded and stored in the placement groove 27 is fixedly connected to the inner wall of the placement groove 27, and a lifting mechanism connected to the fireproof cloth 28 is provided in the box body 1.

[0024] A plurality of control cabinets 12 are centrally installed in the placement cavity 11 for operation, and the wiring harnesses of the plurality of control cabinets 12 are centrally transferred into the first wiring harness frame 2 through the second wiring harness frame 22, and then the wiring harnesses of the plurality of control cabinets 12 are centrally moved out of the box body 1 from the upper end of the box body 1 through the wiring harness seat 21; The design of the first heat dissipation holes 23 can naturally dissipate heat for the multiple control cabinets 12 in the box body 1, and when the heat dissipation fan 24 is working, the heat in the box body 1 can be discharged to the outside, and the external cold air can enter the box body 1 through the first heat dissipation holes 23, so as to achieve the purpose of effectively dissipating heat in the box body 1; The temperature sensor 26 monitors the temperature inside the box 1 in real time and transmits the temperature to the control board 14 in real time. When the control board 14 detects through the temperature sensor 26 that the temperature inside the box 1 is getting higher and higher, the control board 14 increases the working intensity of the cooling fan 24 to gradually improve the cooling effect on the box 1. When it is detected that the temperature inside the box 1 is gradually decreasing, the working intensity of the cooling fan 24 is gradually reduced to gradually reduce the cooling effect on the box 1. This design can monitor the temperature inside the box 1 intelligently in real time, and can adjust the cooling effect inside the box 1 according to the actual temperature inside the box 1. The processor inside the control board 14 With powerful data processing capabilities and in accordance with preset intelligent algorithm logic, it can deeply analyze operating data and accurately judge the operating status of equipment. It can also push key information to the remote monitoring terminal in real time with the help of multiple wireless communication links such as 4G / 5G or Wi-Fi. The staff can intuitively monitor the trends of various data through the remote monitoring terminal, and can ensure that the internal temperature of the box 1 is stably controlled within the ideal range according to the preset threshold, efficiently dissipate the accumulated heat during operation, and ensure the long-term and stable operation of the equipment. The cooling fan 24 flexibly adjusts its speed according to the instructions of the control panel 14, and the control panel 14 accurately controls the cooling fan 24 according to the preset temperature and air volume control curve based on the real-time feedback of the temperature sensor.

[0025] The smoke alarm 25 monitors the interior of the box 1 in real time. When the smoke alarm 25 detects a fire inside the box 1, the smoke alarm 25 transmits a signal to the control panel 14. At this time, the control panel 14 controls the lifting mechanism to start working, and the lifting mechanism drives the upper end of the fireproof cloth 28 to move upward quickly. The upper end of the fireproof cloth 28 quickly fits with the upper inner wall of the box 1, thereby wrapping multiple control cabinets 12 in the fireproof cloth 28. This design can prevent the spread of fire and protect the surroundings. It can also seal the control cabinet 12 to reduce the contact between external oxygen and the fire source, thereby achieving the effect of extinguishing the fire. This design can automatically seal multiple control cabinets 12 to prevent the spread of fire after monitoring the occurrence of a fire. At the same time, it can also have a certain fire extinguishing effect and can minimize the property loss caused by the fire before the staff discovers the fire.

[0026] The lifting mechanism includes a sealing frame 3 connected to the upper end of the fireproof cloth 28 , a lifting assembly connected to the sealing frame 3 is provided on the upper side of the box body 1 , and a sealing strip matching the sealing frame 3 is provided on the upper inner wall of the box body 1 .

[0027] When the lifting mechanism starts to work, it drives the sealing frame 3 to move upward, and the sealing frame 3 drives the fireproof cloth 28 to move upward quickly. The design of the sealing strip can improve the sealing effect between the sealing frame 3 and the upper inner wall of the box body 1, thereby increasing the sealing effect of the control cabinet 12.

[0028] The lifting mechanism includes a winding rod 31 rotatably assembled on the upper side of the box body 1, and a motor 32 is provided on the upper side of the box body 1 that is transmission-connected to the winding rod 31. Four lifting wires 33 are fixedly wound around the outer surface of the winding rod 31, and the other ends of the four lifting wires 33 are slidably sealed and extended into the placement cavity 11 and are respectively connected to the four corners of the sealing frame 3.

[0029] The control board 14 controls the motor 32 to start working, and the motor 32 drives the winding rod 31 to start rotating. The winding rod 31 winds the four lifting lines 33 at the same time. Since the four lifting lines 33 are connected to the sealing frame 3, the sealing frame 3 can be driven to move upward in the box body 1. When the motor 32 drives the winding rod 31 to rotate in the opposite direction, the winding of the lifting lines 33 can be gradually canceled, and the sealing frame 3 moves downward and resets under the action of gravity.

The design of the limiting groove 36 can store the sealing frame 3, and when the sealing frame 3 is in the limiting groove 36, the flatness of the lower surface of the placement cavity 11 can be maintained.

[0034] The outer surface of the box door 13 is provided with a plurality of second heat dissipation holes 37. The design of the plurality of second heat dissipation holes 37 can further improve the heat dissipation effect inside the box body 1.
