Description

Technical Field

[0001] The present invention relates to the technical field of power distribution network safety protection, and in particular to a terminal safety protection device for a power distribution network. Background Art

[0002] The distribution network is composed of overhead lines, cables, towers, distribution transformers, disconnectors, reactive power compensators and some ancillary facilities, and plays an important role in distributing electric energy in the power grid. The intelligent distribution network system and power automation system are composed of three parts: the master station, the communication system, and the automated monitoring terminal equipment, forming a complete information transmission and processing system to achieve remote management of the distribution network operation. Among them, the distribution box is an important component, and it is equipped with many important electronic components. The safety of electronic components is the key to determine the safety and reliability of power supply.

[0003] Most of the protections that exist in the distribution box in the prior art during use are leakage protection and high temperature protection, but different protection methods are targeted at different distribution boxes, which is not convenient for integrating multiple different protection functions into one, resulting in the problem that the existing distribution box can complete high temperature protection while lacking other leakage protection.

[0004] The Chinese invention patent named "A terminal safety protection device for a distribution network" (application number 202411042048.9) discloses that it mainly realizes the dehumidification function inside the box to prevent excessive humidity from affecting the service life of electronic components. At the same time, it prevents excessive humidity from causing the performance of the insulating material inside the distribution box to deteriorate, thereby causing short circuits, leakage and other faults. However, the protection function of this structure lies in the control of temperature and humidity. However, short circuits often occur during the use of distribution boxes, and dust accumulation after long-term use causes leakage after short circuits, which puts workers at risk of live operations, posing a safety hazard. Therefore, according to the applicant's invention, a multiple safety protection device for distribution boxes is invented to solve the problem that the traditional distribution box has a relatively single safety protection range. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a terminal safety protection device for a distribution network, which solves the problem that the safety protection range of traditional distribution boxes is relatively single.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a terminal safety protection device for a distribution network, comprising: a distribution box, a cooling treatment box and a dust collection box, one side of the distribution box is fixedly connected with a cooling treatment box, the upper and lower sides of the cooling treatment box are fixedly connected with water tanks, the number of the water tanks is two, a return pipe is fixedly connected between the water tanks on one side, a cooling pipe is fixedly connected in the middle between the water tanks, a circulating pump is fixedly connected to one side of the inner side of the water tank at the bottom, the output end of the circulating pump is fixedly connected to the cooling pipe, and both ends of the front side of the water tank at the top are fixedly connected with semiconductor heat dissipation fans; a fixed concave plate is fixedly connected to one side of the inner top of the distribution box, a plurality of support springs are fixedly connected to one side of the inner side of the fixed concave plate, and one end of the support spring is fixedly connected to a conductive aluminum plate; a dust collection box is fixedly connected to the bottom end of the other side of the distribution box, a wind pump is fixedly connected to the inner top of the dust collection box, a dust collection pipe is fixedly connected to the middle of the top of the dust collection box, and one end of the dust collection pipe runs through the interior of the distribution box.

[0013] As a further improvement of the present invention, a semiconductor refrigeration chip is arranged on the inner side of the semiconductor heat dissipation fan, and a heat-conducting aluminum sheet is arranged on the outer side of the semiconductor heat dissipation fan.

The first motor is used to drive the fan to rotate. After the rotation, the internal gas of the distribution box is circulated.

The dust inside the distribution box is processed through this structure, which can prevent the short circuit of the line caused by excessive dust and can also play a protective role.

A return pipe 23 is fixedly connected between the water tanks 25 on one side, and a cooling pipe 10 is fixedly connected to the middle between the water tanks 25. The first motor 3 drives the rotation of the fan to blow and circulate the cooling gas generated by the cooling pipe 10 to the inside of the distribution box 1, thereby realizing the cooling effect of the cold air on the inside of the distribution box 1 and improving the cooling efficiency. A circulating pump 24 is fixedly connected to one side of the inner side of the bottom water tank 25. The circulating pump 24 extracts the cooling liquid, and then circulates it through the cooling pipe 10. The output end of the circulating pump 24 is fixedly connected to the cooling pipe 10.

[0020] In the present invention, both ends of the front side of the top water tank 25 are fixedly connected with semiconductor heat dissipation fans 22, and the heat generated by the semiconductor refrigeration chip is dissipated by the semiconductor heat dissipation fan 22 to achieve the cooling effect, and the cooling heat is discharged through the upper outside of the cooling treatment box 2, and the outside of the cooling treatment box 2 is fixedly connected with a fixed net 4, and the dust is blocked by the fixed net 4. A first motor 3 is fixedly connected to the middle part of the outside of the cooling treatment box 2, and the fan is driven by the first motor 3 to rotate, and the internal gas of the distribution box 1 is circulated after rotation. The driving end of the first motor 3 is fixedly connected with a fan, and a semiconductor refrigeration chip is arranged on the inner side of the semiconductor heat dissipation fan 22, and the internal coolant of the water tank 25 is cooled by the semiconductor refrigeration chip. A heat-conducting aluminum sheet 21 is arranged on the outer side of the semiconductor heat dissipation fan 22, and heat is conducted by the heat-conducting aluminum sheet 21, so that efficient heat dissipation can be achieved.

[0021] In the present invention, a fixed concave plate 11 is fixedly connected to one side of the internal top end of the distribution box 1, and the conductive aluminum plate 19 can be fixed by the fixed concave plate 11.

The conductive aluminum plate 19 and the connecting wire 18 can be resisted by the support spring 20 structure. One end of the support spring 20 is fixedly connected to the conductive aluminum plate 19. When the line becomes loose during the use of the distribution box 1 or leakage occurs, the shell of the distribution box 1 becomes energized and the conductive aluminum plate 19 and the connecting wire 18 are energized.

[0022] In the present invention, the second motor 26 is fixedly connected to both sides of the bottom end of the distribution box 1. Dust will accumulate inside the distribution box 1 during use. At this time, the second motor 26 is driven to drive the fan blade 13 to rotate. After rotation, the dust inside the distribution box 1 can be lifted. The driving end of the second motor 26 is fixedly connected to the fan blade 13. A heat dissipation port 14 is provided on the other side of the distribution box 1. The gas is discharged through the heat dissipation port 14 to achieve gas circulation and thus achieve heat dissipation. A dustproof net is fixedly connected to the inside of the heat dissipation port 14. A box door 8 is hinged on the front side of the distribution box 1. An alarm light 6 is fixedly connected to one corner of the top of the distribution box 1. The alarm light 6 is started by the flow of current and the adaptation of the current converter, thereby achieving a warning effect and preventing damage to the equipment. A connecting wire 18 is fixedly connected to the bottom end of the alarm light 6. One end of the connecting wire 18 is electrically connected to the conductive aluminum plate 19. Through holes 5 are provided at both upper and lower ends of one side of the distribution box 1. The connecting wires required for the distribution network are passed through the through holes 5 to pass through the grid connection box 9 for connection.

[0023] In the present invention, a dust box 15 is fixedly connected to the bottom end of the other side of the distribution box 1, and the dust and impurities floating inside the distribution box 1 are collected by the dust box 15.

The structure of the air pump 17 can make the inside of the dust box 15 in a negative pressure state, which can facilitate the adsorption of the external air of the dust hood 12 into the dust pipe 7 to complete the circulation of dust and air. The input end of the air pump 17 is provided with a filter screen, which can block the floating dust to prevent damage to the air pump 17. After the air pump 17 at the top end of the dust box 15 is driven, the inside of the dust box 15 is in a negative pressure state.

[0024] In the present invention, when in use, the connection wires required for the distribution network are passed through the through hole 5 to pass through the grid connection box 9 for connection, and after the connection, the box door 8 is closed. After closing, it can be driven by the first motor 3 to rotate the fan, and after rotation, the internal gas of the distribution box body 1 is circulated, and after circulation, it is discharged through the heat dissipation port 14 to achieve the circulation of gas and thus realize the heat dissipation effect. At the same time, when the temperature is high, the internal coolant of the water tank 25 can be cooled by the semiconductor refrigeration chip. After cooling, the circulating pump 24 extracts the coolant, and then circulates it through the cooling pipe 10. During the circulation process, the first motor 3 drives the rotation of the fan to blow and circulate the cooling gas generated by the cooling pipe 10 to the inside of the distribution box body 1, thereby realizing the cooling effect of cold air on the inside of the distribution box body 1 and improving the cooling efficiency. When the line becomes loose or leakage occurs during the process, the shell of the distribution box 1 becomes charged. At this time, the conductive aluminum plate 19 and the connecting line 18 are energized. Through the flow of current and the adaptation of the current converter, the alarm light 6 is activated to achieve a warning effect, which can prevent damage to the equipment and cause the risk of live operation. Dust will accumulate inside the distribution box 1 during use. At this time, the second motor 26 is driven to drive the fan blades 13 to rotate.
