Description

TECHNICAL FIELD

[0001] The utility model relates to ring main unit technical field, concretely is intelligent strong wind circulation anti -condensation device, BACKGROUND

[0002] This part of the statement only provides the background information related to the present disclosure, and these statements may constitute the prior art. In the process of implementing the utility model, the inventors found that at least the following problems exist in the prior art.

[0003] The air under natural conditions is composed of dry clean air, water vapor and small dust. The water vapor that air can contain is proportional to the ambient temperature, that is, the higher the ambient temperature, the more water vapor the air can contain. The dew point temperature refers to the highest temperature at which condensation occurs in air of a certain humidity. When the air temperature drops below the dew point temperature, part of the water in the air will be precipitated, forming dew or frost, which is called condensation.

[0004] Taking power equipment as an example, the bottom of the power equipment (such as switch cabinet, electrical cabinet, screen cabinet, etc., hereinafter referred to as ring network cabinet) is a cable trench. The humid air in the cable trench continuously rises through the equipment cable chamber passage. When the humid air meets the metal and plastic components such as the top plate and terminal inside the equipment, the moisture is precipitated in the form of liquid water at the cold and hot exchange interface due to the high surface temperature of the components, and then condensation occurs.

[0005] Condensation can cause the following hazards to ring network cabinets:

[0006] (1) Partial discharge

[0007] Condensation on the surface of power equipment components can significantly reduce the initial discharge voltage and flashover voltage of the components, significantly enhance the discharge, and even produce strong partial discharge, which quickly reduces the insulation strength of the equipment and causes insulation damage to the power equipment.

[0008] (2) Line fault

[0009] Condensation mixed with dust adheres to the top end of the terminal box. When the dew water accumulates a certain weight, it will drip down on the internal exposed working elements such as the terminal, which can cause a path to be formed between the two poles of the metal element, resulting in short circuit and burnout of the component, loss of normal function; for example, condensation mixed with dust directly adheres to the terminal, which can create a non-existent conductive path, causing logic pulse confusion, and then causing power supply short circuit, electronic component failure and other faults, and more serious accidents such as fire and explosion may occur.

[0010] (3) Creepage

[0011] When liquid water mixes with dust inside the equipment, a corresponding conductive channel is generated, which affects the electrical insulation of the equipment, causes the insulation material to present a charged phenomenon, and eventually leads to insulation damage, inter-phase short circuit and other faults.

[0012] (Four) institutional corrosion

[0013] The transmission mechanism of the ring main unit that has been running in a humid environment for a long time often encounters deformation, bending, broken connecting rod, broken crank arm, broken transmission pin, etc., causing difficult and cumbersome operation, some connecting rods have small stiffness and serious corrosion, and mechanical vibration is severe during operation, which can cause problems such as jamming of the operating mechanism, breaking of the fuse pipe connecting rod, and refusal of the circuit breaker to split, resulting in inter-phase short circuit tripping or single-phase grounding faults, and even more serious accidents such as step tripping or fire, which seriously affects the safe operation of the power system.

[0014] In view of the above practical problems, there are two types of anti-condensation devices on the market, but the effect is limited and cannot well solve the condensation problem of the ring main unit. The first type is heating type: composed of ordinary fans, heating sheets, humidity sensors, etc. When the humidity sensor measures that the humidity exceeds the set upper limit value, the heating sheet and fan are started to heat the surrounding air, thereby changing the dew point and preventing condensation. For example, the applicant has designed a "ring main unit strong air circulation anti-condensation device" (application number 201721402528.7), which is of this type. But in practice, it is found that because ordinary fans are used, the air volume is 6.8-10 CFM, and the maximum air volume converted is only 10 m 3 / h. And the volume of a single cabinet of the ring main unit is about 4 m 3 , and there are various lines, equipment, mechanisms, etc. in the cabinet to block the air path. The small air volume causes the back and top of the above structure to form a blind area, so that the air inside cannot form a circulation, and the dehumidification effect is limited.

[0015] The second type is the cooling and drainage type. It is composed of ordinary fans, semiconductor refrigerating sheets, humidity sensors, etc. When the humidity sensor measures that the humidity exceeds the set upper limit value, the semiconductor refrigerating sheet and fan are started. When the semiconductor refrigerating sheet is working, the cold end forms a difference of 30 degrees or more with the ambient temperature, and the water vapor in the air is condensed on the surface of the semiconductor refrigerating sheet and is drained out of the cabinet through the drain pipe. This type of product has two problems, first, it also uses a 10 m 3 / h fan, and the air exchange effect is limited. At the same time, a drainage hole position is left below the device, which requires drilling a drainage hole and separately laying a drainage channel in the cabinet, increasing the construction work quantity.

DETAILED DESCRIPTION

[0036] The utility model is further illustrated below in combination with the drawings, and the embodiments of the utility model are only used for illustrating the utility model but not limiting the utility model, and various substitutions and changes can be made according to the ordinary technical knowledge and conventional means in the art without departing from the technical thought of the utility model, which should be included in the scope of the utility model.

[0037] For example, Figure 1Or 2 or 3, the intelligent strong wind circulation anti-condensation device, comprising a shell and a fan, a heating plate 10, a sensor and a temperature control device 11 arranged in the shell; the fan, the heating plate 10 and the sensor are connected with the temperature control device 11; the fan is a cross-flow fan 1 located at the lower end of the shell; the side and the bottom of the shell are provided with air inlets 5, and the top is provided with an air outlet 6; the heating plate 10 is arranged between the cross-flow fan 1 and the air outlet 6; the positions and widths of the air inlets 5 and the air outlet 6 are matched with the cross-flow fan 1. The shell is provided with a plurality of mounting holes 3, and the shell can be fixed to the bottom of the side wall of the ring main unit through the mounting holes 3.

[0038] In order to solve the problem of small air volume and limited dehumidification effect, the original fan is replaced with a cross-flow fan 1. The cross-flow fan is an air circulation device composed of a motor, a fan wheel and a peripheral fixed guide cover. The motor drives the fan wheel to rotate, and the generated air flow is guided by the guide cover to one direction, thereby forming a horizontal wind flow. The principle of cross-flow fan is to use the rotational motion on the fan wheel to make the gas flow and generate wind power, mainly using the pressure difference of air, pushing the air through the guide cover and forming the wind flow through the blades of the fan wheel. Its working principle is similar to that of the ceiling fan of the glass window, but the air volume is larger, and it is generally used for air circulation, ventilation, heat dissipation and the like.

[0039] The cross-flow fan 1 can adopt the existing product, and the air volume is 180 to 210 m 3 / h. For example, the cross-flow fan 1 of product signal MFD30290A12BF has a cold-rolled plate shell and an aluminum alloy impeller, and the length, width and height dimensions are 336mm*50mm*48, the voltage is 12V / 24V, and the air volume is 3m 3 / minute. The cross-flow fan 1 is 18-20 times the air volume of a general fan. According to the characteristics of this cross-flow fan, the air path system is redesigned, and the import and export mode of the air duct is optimized, so that the strong hot air is blown out directly from the top of the device. Due to the huge air volume and air pressure, the strong hot air can quickly blow to any corner in the cabinet, and the internal air circulation can be realized more than 40 times in one hour. In this way, the humid and cold air in the ring main unit can be sucked into the heating chamber of the device by the cross-flow fan 1, and then blown into the ring main unit through the air outlet 6, thereby increasing the dew point. And because it uses a cross-flow fan 1, the huge air volume can form a strong wind, which can blow well to all parts of the ring main unit, ensuring the uniformity of the temperature and humidity in the ring main unit, ensuring that the temperature in the ring main unit can be raised to a safe temperature, avoiding the temperature difference between the low-temperature air at the bottom and the surface of the heating element, thereby effectively preventing condensation, solving the humidity problem in the ring main unit, and ensuring the safe operation of the power equipment.

[0040] The air inlet 5 and the air outlet 6 have the same area as the cross-flow fan 1. Since the air inlets 5 are arranged on the side and bottom of the shell, the air inlet area and quantity are greatly increased, and the top of the device is the high-temperature strong air outlet after being heated by the heating plate 10.

[0041] The cold air in the ring main unit is quickly heated by the heating plate 10 after being sucked into the air inlet. The maximum temperature of the heating plate 10 is about 150 degrees. The hot air after heating is blown out through the air outlet. The device is installed on the lower side of the ring main unit, and according to the principle of automatic upward movement of hot air, and with the help of wind force, the hot air is automatically circulated from the bottom to the top of the ring main unit. After multiple cycles, the data measured by the sensor is compared with the set value, and when the humidity and temperature reach the safety value, the device automatically stops running.

[0042] At the same time, the control logic of the present application is also optimized and improved. Specifically, even if the humidity in the air is not high, when the temperature reaches the warning temperature, the device is designed to automatically start the strong wind heating mode. Through the circulation system, the temperature in the ring main unit is raised to a safe temperature, avoiding the formation of dew point due to temperature difference between the low-temperature air in the bottom and the surface of the heating element, and preventing condensation.

[0043] The overall width of the device is 415 mm, and it can work after being installed on the cabinet. No additional drainage system is needed. The installation is quick and easy to use.

[0044] The sensor mainly includes a temperature sensor and a humidity sensor.

[0045] However, due to the differences in internal lines, equipment, mechanisms, etc. of each ring main unit, although a high-power cross-flow fan 1 is used, there is still a possibility that the above structure blocks the air path, forming a blind area on the back and top of the line and equipment, and the internal air cannot be effectively circulated, reducing the dehumidification effect. In order to solve this problem, as shown in Figure 4 The intelligent strong wind circulation condensation prevention device also includes at least one air guide pipe arranged above the shell; the air guide pipe is a T-shaped pipe, and the upper and lower ends of the air guide pipe are respectively provided with an air guide pipe air outlet 8 and an air guide pipe air inlet 7 matched with the cross-flow fan 1; the middle part of the air guide pipe is provided with an air guide pipe horizontal air outlet 9, which is used to divide the strong hot air entering from the air guide pipe air inlet 7 into the air guide pipe horizontal air outlet 9 and the air guide pipe air outlet 8.

[0046] The air duct inlet and outlet and the air duct transverse outlet 9 have the same area as the outlet 6, so that the high-temperature strong wind blown out of the outlet 6 can be introduced into the air duct and divided. Part of the wind is blown horizontally to the equipment in the ring main unit through the air duct transverse outlet 9, and the other part is blown upward into the air duct above and continues to be divided, so that the application not only blows air upward to complete the large circulation around the ring main unit, but also blows air horizontally to the lines in the ring main unit, so that the back and top of the lines do not form a blind area. In particular, the high-temperature strong wind can be blown into the gap, so as to truly realize 360° without dead angle and achieve uniformity of the temperature in the ring main unit, thereby greatly improving the anti-condensation effect.

[0047] As shown in Figure 4 When there are at least two air ducts, the air duct inlet 7 of the air duct above is aligned with the air duct outlet 8 of the air duct below, so that the high-temperature strong wind blown out of the air duct below can be introduced into the air duct above, thereby realizing multi-level horizontal air flow effect, which is very suitable for the ring main unit with a relatively high cabinet. Moreover, since the cross-flow fan 1 has a wind volume that is dozens of times larger than that of an ordinary fan, the wind volume blown horizontally and upward can be ensured even after multiple divisions in the air duct.

[0048] Moreover, the horizontal multi-level air flow can also slow down the rising speed of the humid air in the cable trench to a certain extent, and mix with the humid air to improve the temperature and ensure the dehumidification effect.

[0049] Since the cross-flow fan has a special structure, sand and other impurities are not allowed to fall into the fan, otherwise the fan will be burned out and the fan blades will be broken. Therefore, in addition to the horizontal division of the air flow, since the air duct is arranged directly above the shell and is consistent with the outlet 6, the entire outlet 6 can be covered, which can effectively prevent sand and other impurities from falling into the cross-flow fan 1 through the outlet 6, and avoid damage to the cross-flow fan 1.

[0050] Preferably, the air duct inlet 7 of the first air duct closest to the shell is connected or in contact with the outlet 6 of the shell, so as to better ensure that the impurities above do not fall into the cross-flow fan 1.

[0051] In order to better form a circulation of the high-temperature strong wind blown out of the cross-flow fan 1 in the ring main unit, the air duct transverse outlet 9 is directed to the gap of the equipment in the ring main unit, so as to ensure uniform temperature and make the air flow blow from the gap to the other end of the equipment. In principle, when the wind blows to the other end of the equipment, it will be dispersed in two directions upward and downward, but since there is wind blown horizontally by other air ducts above, the wind is forced to flow downward and finally returns to the inlet 5 below and on the side of the shell and is sucked into the cross-flow fan 1 again, thereby forming an effective circulation and ensuring the dehumidification effect.

[0052] Preferably, the housing is installed at a specific height from the bottom of the ring main unit so that the rotating airflow can enter from the air inlets 5 at the bottom and side of the housing simultaneously, ensuring effective air circulation.

[0053] The diversion function of the air duct can be achieved through various structures. For example... Figure 6 As shown, the inner wall of the middle section of the air duct is provided with an air guide baffle 12 to divert the strong hot air entering from the air inlet 7 of the air duct to the horizontal air outlet 9 and the air outlet 8 of the air duct. Alternatively, as shown... Figure 5 As shown, the width of the air inlet 7 of the air duct is greater than the width of the air outlet 8 of the air duct, thereby achieving air diversion. This application allows for the design of the number of air ducts based on the actual space size of the ring main unit, and the adjustment of the width ratio of the air guide baffle 12 or the air inlet / outlet of the air duct, so that the horizontal airflow blown out by the air ducts of each layer can achieve the dehumidification effect.

[0054] like Figure 1 As shown in Figure 2, the temperature control device 11 also includes a power / communication interface 2 and a display control screen 4 located on the side wall of the housing.

[0055] This application utilizes an automatic control mode, in conjunction with the host computer communication software "Intelligent Management System for the Internal Environment of Ring Main Unit," to achieve unmanned automatic management, monitoring, and recording of the temperature and humidity environment inside the electrical ring main unit. This effectively prevents condensation, solves the humidity problem within the ring main unit, and fully ensures the safe operation of the ring main unit.
