Description

{Inverter for solar power generation with heat dissipation and earthquake proof function (high voltage distribution board, low voltage switchboard, distribution board, motor control panel, solar connection board, ESS) high voltage distribution board, distribution board, motor control board, sunlight connection band, ESS)

The present invention relates to inverters for solar power generation (high-voltage switchgear, low-voltage switchgear, distribution board, motor control panel, solar connection panel, ESS) (High-voltage switchgear, low-voltage switchboard, distribution board, motor control panel, solar light connection panel, ESS) having a heat dissipation and an earthquake-resistant function.

Generally, a power device generally refers to a solar inverter, a distribution panel, a low-pressure panel, a high-pressure panel, a voltage regulator panel, a motor control panel, and an ESS. Power devices such as a breaker and a magnetic Or control the operation of the system.

Among the various power devices, the most widely used power device is an electric device for securely supplying a relatively high power, and is generally installed in a box shape and shielded from the outside.

In a typical switchboard, various units such as a main wiring breaker, an auxiliary wiring breaker, and an earth leakage breaker are installed in the case, and the units are electrically connected to each other. The power supplied from the outside is distributed to the elements, can do.

In addition, a plurality of bus bars for distributing power supplied from the outside are electrically connected to the respective breakers, and one side of the bus bars is connected to the output terminals of the parking terminals, And the auxiliary boom bar is connected to the bus bar bar and supplies the divided power to the respective auxiliary circuit breakers.

In addition, the switchboard includes a high-voltage transformer that converts an extra-high voltage to a low voltage in a closed enclosure, a breakdown-point automatic switch that switches a high-voltage input line to a meter transformer, and a high-voltage fuse of a Korean wave type. Heat is generated in a high-voltage transformer or the like, and the temperature inside the enclosure rises.

Excessive rise of the internal temperature of the enclosure in the switchboard may degrade the operation efficiency and accuracy of various parts and devices, and may cause fire. Therefore, most of the internal temperature monitoring circuit is installed, When it is detected that the temperature has been reached, the cooling fan is started immediately to forcefully drop the internal temperature of the enclosure.

However, since the heat dissipation operation of the switchboard through forced ventilation causes inflow of fine dust from the outside and also disperses and relocates the fine dust in the interior thereof, There is a problem in that the number increases.

In order to solve the above problems, the upper plate portion and the lower plate portion of the cabinet of the cabinet are provided with a heat dissipation port and a ventilation port for cooling internal equipment, respectively.

However, as described above, there is a limit to the heat dissipation of the enclosure of the switchboard only by the heat dissipation holes and the ventilation holes for cooling the internal devices in the upper and lower panels of the enclosure of the switchboard, so that more effective heat dissipation technology is urgently needed.

In addition, the switchgear including the inverter for solar power generation is equipped with a power receiving facility for receiving high pressure and extra high voltage supplied from the substation, a substation for lowering the high voltage, extra high voltage received from the substation to commercial voltage, And an enclosure for receiving the power reception equipment, the power supply equipment, and the power distribution equipment, and is generally fixed to the ground. Therefore, in the conventional switchboard, mechanical vibrations or vibrations due to earthquakes are transmitted as they are to the switchboards.

The reason why the above-mentioned switchboard is installed on the ground is that, when mechanical vibration or vibration or shock due to earthquake occurs, the electric devices inside the switchgear and the electric wires such as the wires connecting these electric devices and protective relays are damaged or damaged So that the interruption of the power supply and the fire can be caused by the trouble generated thereby.

As shown in FIG. 1, a solar power inverter having a heat dissipation and earthquake-proof function according to the first embodiment of the present invention is installed in an internal space and incorporates various electric units to supply electric power generated from external sunlight An aluminum heat sink 120 formed on the upper surface of the inverter housing 110 and having a surface of carbon nanomaterial 121 formed on one side of the inverter housing 110; A carbon nano ground plate 130 connected to the aluminum heat dissipating plate 120 to discharge a surge current or a lightning current to the ground and various electric units built in the inverter enclosure 110, And a ventilation hole 111 formed on one side of the inverter housing 110. The aluminum heat sink 120 has a triangular concavo-convex structure.

Here, the inverter-related circuit of the solar inverter and various input / output power cables and pipes are housed in the inverter enclosure 110. Meanwhile, inverter circuits and input / output power cables housed in the inverter enclosure 120 can utilize those conventionally employed, so that a detailed description thereof will be omitted herein.

It is needless to say that the protection range of the present invention is not determined depending on the type of each article, as the type of the article to be stored in the inverter enclosure 110 can be determined by a person skilled in the art.

Meanwhile, the inverter enclosure 110 is generally installed in a place exposed to direct sunlight, and it is necessary to adequately cool the heat generated during the operation of the inverter circuit. Accordingly, in order to dissipate the heat generated in the inverter housing 110 to the outside, an aluminum heat sink having excellent heat transfer performance is used, and a carbon nano material 121 is formed on the surface of the aluminum heat sink 120, You can maximize it.

In addition, the aluminum heat dissipation plate 120 formed at the upper end of the inverter housing 110 is formed in a triangular shape, and a passage of air is formed between the gaps and the gap, and heat is induced in the direction of the ventilation hole 140 along the slope, The heat generated in the heat exchanger 120 can be discharged more efficiently.
