Description

Technical Field

[0001] The utility model relates to the technical field of capacitor cabinets, in particular to a low-voltage reactive power compensation integrated capacitor cabinet. Background Technique

Therefore, the reactive power compensation device plays a very important and indispensable role in the power supply system. Reasonable selection of the compensation device can minimize the losses of the power grid and improve the power grid quality.

The fan is arranged on the top of the cabinet body, and the air outlet pipe of the fan is communicated with the inside of the cabinet body. Two wind baffles are respectively fixed on both sides of the electrical component fixing plate, and the wind baffle extends from the top of the electrical component fixing plate to the bottom of the electrical component fixing plate; a partition plate and a wind guiding plate are fixed on the wind baffle, and the partition plate and the wind guiding plate on the same wind baffle are arranged alternately along the height direction of the electrical component fixing plate. The partition plates and the wind guiding plates on the two wind baffles cooperate with each other to form a drainage channel, and an air outlet channel is arranged at the bottom of the cabinet body, and the drainage channel is communicated with the air outlet channel. The cold air is drained through the drainage channel and passes through the entire plate surface of the electrical component fixing plate from top to bottom, improving the heat dissipation effect on the electrical component fixing plate, preventing the capacitor from running at high temperature for a long time, and improving the service life of the capacitor in the cabinet.

Specific embodiments

[0025] The following will further elaborate on the present utility model in detail with reference to the attached drawings.

[0026] Embodiment:

[0027] Refer to Figure 1 - Figure 7, A low-voltage reactive power compensation integrated capacitor cabinet disclosed by the present utility model includes a cabinet body 1. A placement groove 2 is formed on one side of the cabinet body 1 and is hermetically connected with a cabinet door 3. A plurality of placement plates 4 for placing components are arranged at intervals from top to bottom on the inner side wall of the placement groove 2. Temperature detection probes 5 are arranged above each placement plate 4 on the inner side wall of the placement groove 2. A cooling component 6 connected to the plurality of placement plates 4 is arranged on the outer wall of the cabinet body 1 away from the cabinet door 3.

[0028] In this embodiment, since heat is generated when the low-voltage reactive power compensation capacitor cabinet is in use, in order to protect the internal components, it is necessary to cool the temperature inside the capacitor cabinet. However, the direct ventilation method will blow the dust in the air into the capacitor cabinet, resulting in the dust being adsorbed by the electric field of the components inside the capacitor cabinet. And as the use time of the capacitor cabinet increases, the thickness of the dust will also increase, which will damage the internal components, resulting in frequent maintenance of the capacitor cabinet after long-term use and increasing the use cost of the capacitor cabinet.

[0029] Adding dust filters at the air inlet and outlet of the capacitor cabinet will interfere with the air flow, resulting in poor heat dissipation efficiency and affecting the heat dissipation of the capacitor cabinet by the fan.

[0030] Therefore, observing Figure 1 it can be found that the cabinet body 1 is hermetically connected with the cabinet door 3, making the capacitor cabinet integrated, which can prevent the dust in the air from entering the capacitor cabinet and protect the electrical components. Subsequently, observing Figure 5 it can be found that a cooling component 6 is arranged on the outer side of the cabinet body 1, and the placement plate 4 for installing electrical components inside the cabinet body 1 is cooled by the external cooling component 6, which can dissipate the heat of the components inside the capacitor cabinet while ensuring the sealing performance of the capacitor cabinet, further protecting the electrical components inside the capacitor cabinet.

[0031] When observing Figure 4 it can be found that a temperature detection probe 5 is arranged above each placement plate 4, which can independently measure the temperature of the electrical components on each layer, be used to accurately monitor the temperature of the components inside the capacitor cabinet, avoid the abnormal increase in the temperature of the components and damage, and further improve the practicability of the capacitor cabinet.

[0032] In a further preferred embodiment of the present utility model, as Figure 5 and Figure 7 shown, the cooling component 6 includes a water storage tank 61, a water pump 62 and a water circulation pipe 63. Two water storage tanks 61 are provided and symmetrically installed on both sides of the cabinet body 1. A water pump 62 is fixedly connected to the top of one of the water storage tanks 61. The water pump 62 is connected to the other water storage tank 61 through a water inlet pipe 7. A water circulation pipe 63 for cooling the components inside the cabinet body 1 is arranged between the two water storage tanks 61.

[0033] In this embodiment, since the cabinet body 1 and the cabinet door 3 are sealed and installed, the capacitor cabinet is integrally arranged, which will cause the heat in the capacitor cabinet to not be directly dissipated to the outside, affecting the heat dissipation of the capacitor cabinet.

[0034] Therefore, observing Figure 5 it can be found that two water storage tanks 61 are connected to the outer side wall of the cabinet body 1. Subsequently, a water pump 62 is installed on one of the water storage tanks 61, and the water pump 62 is communicated with the other water storage tank 61 through a water inlet pipe 7. Moreover, a water circulation pipe 63 for water circulation is installed between the two water storage tanks 61, and the water circulation pipe 63 passes through the cabinet body 1 and enters the interior of the cabinet body 1, so that the low-temperature water can take away the heat dissipated by the electrical components, thereby achieving the effect of heat dissipation of the capacitor cabinet.

[0035] In a further preferred embodiment of the present utility model, as Figure 5 and Figure 7 shown, a plurality of the water circulation pipes 63 are arranged at intervals from top to bottom and are correspondingly arranged in the placement plate 4 one by one.

[0036] In this embodiment, since the heat conduction efficiency of the gas is inferior to that of the solid, the effect of cooling the water circulation pipe 63 by exchanging heat with the air is worse than the effect of directly cooling the electrical components. Therefore, observing Figure 5 and Figure 7 it can be found that a plurality of water circulation pipes 63 are provided and are correspondingly arranged in the placement plate 4 for installing electrical components one by one, so that the water circulation pipes 63 can directly take away the heat of the placement plate 4, thereby using the placement plate 4 to quickly take away the heat of the electrical components, achieving the effect of cooling the electrical components and improving the protection performance of the electrical components.

[0037] In a further preferred embodiment of the present utility model, as Figure 6 shown, the placement plate 4 is composed of a bottom plate 41, a heat-conducting filler 42 and a support plate 43. Among them, the bottom plate 41 is fixedly connected to the inner side wall of the placement groove 2, a cooling groove 8 for laying the water circulation pipe 63 is formed in a concave shape at the top of the bottom plate 41, a heat-conducting filler 42 for transferring heat is filled outside the water circulation pipe 63 in the cooling groove 8, and a support plate 43 in contact with the heat-conducting filler 42 is fixedly connected to the opening of the cooling groove 8.

[0038] In this embodiment, since the water circulation pipe 63 is arranged in the placement plate 4 to enhance the cooling effect on the electrical components, the heat conduction efficiency of the placement plate 4 is extremely important for the heat dissipation of the electrical components. Therefore, observing Figure 6 it can be found that a cooling groove 8 is formed at the top of the bottom plate 41, and the water circulation pipe 63 is laid in the cooling groove 8 to increase the length of the water circulation pipe 63, thereby increasing the heat conduction area and improving the heat dissipation efficiency.

[0039] Subsequently, a heat-conducting filler 42 is filled in the cooling tank 8, and the support plate 43 installed on the top of the bottom plate 41 is brought into contact with the heat-conducting filler 42. By utilizing the heat-conducting filler 42 to accelerate the heat transfer, the heat exchange efficiency of the electrical components can be further improved, thereby further enhancing the cooling effect on the electrical components.

[0040] Among them, the above-mentioned heat-conducting filler 42 is a filler such as alumina, magnesia, zinc oxide, aluminum nitride, boron nitride, silicon carbide, etc. that can improve the thermal conductivity of the material.

[0041] In a further preferred embodiment of the present invention, as Figure 2 shown, a refrigerator 9 is provided in the middle of the water inlet pipe 7, and the side wall of the refrigerator 9 is fixedly connected to the side wall of the cabinet body 1.

[0042] In this embodiment, since the cooling water will heat up after taking away the heat of the electrical components, and the cooling efficiency of allowing the cooling water to exchange temperature with the outside air is poor, the temperature of the cooling water will gradually increase with the increase of the number of cycles, affecting the subsequent cooling effect.

[0043] Therefore, it can be observed that Figure 2 a refrigerator 9 is provided on the outer side wall of the cabinet body 1, and the refrigerator 9 is used to cool the cooling water flowing in the water inlet pipe 7 to ensure that the temperature of the cooling water will not increase, thereby ensuring the cooling effect of the cooling water on the electrical components and further enhancing the protection performance of the electrical components.

[0044] In a further preferred embodiment of the present invention, as Figure 7 shown, a plurality of pressure valves 10 are provided in the water storage tank 61 connected to the water pump 62, and the plurality of pressure valves 10 are arranged at the water inlets of the water circulation pipes 63 in a one-to-one correspondence.

[0045] In this embodiment, since the water pressure is the highest at the outlet of the water pump 62 and the lowest away from the outlet when the water pump 62 pumps water into the water storage tank 61, the water flow velocity in the water circulation pipe 63 near the outlet of the water pump 62 is the fastest, and the water flow velocity in the water circulation pipe 63 away from the outlet of the water pump 62 is the slowest, affecting the synchronous heat dissipation of the electrical components in the cabinet body 1.

[0046] Therefore, a plurality of pressure valves 10 are provided in the water storage tank 61, and the pressure valves 10 are arranged at the water inlets of the water circulation pipes 63 in a one-to-one correspondence to synchronously increase the water pressure in the water storage tank 61. Subsequently, when the pressure exceeds the threshold of the pressure valve 10, the pressure valve 10 is opened to allow the cooling water to enter the water circulation pipes 63 synchronously, so as to ensure that the flow velocity in each water circulation pipe 63 is the same, thereby enabling the electrical components in the cabinet body 1 to maintain synchronous heat dissipation and further enhancing the practicality of the integrated capacitor cabinet.

[0047] The embodiments of this specific implementation manner are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model shall be covered within the protection scope of the present utility model.
