Description

[0001] PHOTOVOLTAIC CONNECTOR [0002]

The present invention relates to a connecting panel having a solar warning device capable of notifying a fault, and more particularly, to a connecting panel having a solar noise notification device capable of generating a beep at the user side when abnormal power is produced from a solar panel (solar panel)

Also, even if the power is normally generated, if the output power via the inverter does not flow in the direction of the commercial power, a beep is generated to inform the user

At sunrise and sunset, it is about a connection board that does not generate a sound even if abnormal power production is made.

Generally, the solar cell connecting unit collects the direct current generated from a plurality of solar cell modules included in the solar power generation system and outputs the collected direct current to the inverter included in the solar power generation system.

Such a photovoltaic connection panel includes an input terminal, a fuse, a diode, and an output terminal

The power output from this connection module is again output to the commercial current through the inverter and the breaker.

The solar power generation system is composed of a module which is the minimum unit for extracting electricity by combining the cells, which are the minimum units that generate electricity due to the potential difference between the p-type semiconductor and the n-type semiconductor,

A solar cell including an array in which a plurality of the modules are arranged in series or in parallel can be provided. In this case, a position tracking device that rotates and tilts according to the position of the sun, i.e., the sun's trajectory, The photovoltaic system is provided with an electrically connected connection panel to supply electricity generated from the solar cell to the inverter,

Such a conventional connection module is disclosed in Korean Registered Patent No. 930132 (published on Dec. 8, 2009), in which a power supplied from an array of solar cells in a solar power generation system which has been used for a long time is charged by a battery or supplied to an inverter In addition to the technology that only performs the functions, a monitoring function is provided that can stably supply the DC power to the inverter by combining the DC power generated from the respective series modules of the solar cells into the parallel group and monitor the solar cell voltage and current .

Recently, as the supply of solar power connection system has been rapidly increased, the operation status of the PV system is remotely diagnosed and the monitoring system is applied.

However, such a diagnostic monitoring system can be applied to a diagnostic monitoring system in a large-capacity large-capacity solar cell connection panel,

 In the case of the household solar power generation system for single-person households, the application of the connection monitoring monitor system is not realistic considering the cost.

Therefore, even if a problem occurs in the solar power generation system, the problem can not be grasped and the following difficulties are occurring.

The following is a summary of the difficulties when the installer of the photovoltaic power plant cites the following.

Consumers (users) can not produce electricity due to heavy snowfall, but they perceive that they are producing. They ask for demolition, saying that it is a product that can not produce electric power at the installer side of Chu Hui

It is also demanding demolition even after it is unable to produce electricity due to nearby obstacles (eg, shadows from other facilities on the roof).

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems,

If abnormal power is generated from the solar panel, it will generate a beep to the external manager and if the output power passing through the inverter does not flow in the direction of commercial power even though the power is normally produced,

At sunrise and sunset, there is an abnormal power generation, and at this time, it provides a connection class that does not generate a sound.

The above and other objects are further elucidated in detail.

The connection module of the present invention, which will be described later, may include an inverter.

For reference, the power generated from a single solar cell module has a larger capacity than that of a single solar cell, but it can be used as a power source for a small-sized device, and the amount of power required to supply generated power to a general commercial power system is inevitable.

For this reason, when a power system is connected to generate power, several solar modules are connected in one group.

In this way, a plurality of groups of one group are connected to one connection group, and the electric power produced by the plurality of groups is collected and supplied as a commercial current through the inverter.

Referring to the flow chart of FIG. 1,

There is a first group of solar cells 1 module (referred to as a first solar panel 80) and a first input terminal 10 for receiving power produced by the first solar panel 80, (Hereinafter referred to as " first breaker ") for receiving and outputting the power output from the first circuit breaker 10, and a first diode 12 for receiving and outputting the power output from the first circuit breaker 11. [ 1 group (100) and:

Another group of solar cell 2 modules (referred to as a second solar panel 81) and a second input terminal 20 to which power produced by the second solar panel 81 is input, A fuse and a circuit breaker (hereinafter referred to as a second circuit breaker) for receiving and outputting power output from the terminal 20,

A second group 200 having a second diode 22 for receiving and outputting power output from the second circuit breaker 21,

A collective output terminal (60) for collecting the power output to the second group (200);

An inverter 300 for receiving and outputting power output from the combined output terminal;

And outputting it as the commercial power (400) via the inverter (300)

Are connected to the power wiring line 3 'corresponding to the first group 100 and the power wiring line 4' corresponding to the second group 200 to detect the power value, Detection sensor units (5, 6);

The control unit 85 is connected to the first and second detection sensor units 5 and 6,

The control device 85 calculates the power value flowing in the first group 100 and the power value flowing in the second group 200 so that the power values of the first group 100 and the second group 200 are significantly different from each other A Korean dictionary) is generated, the user is controlled to generate a dial tone.

The electric power wiring line 3 'corresponding to the first group 100 and the electric power wiring line 4' corresponding to the second group 200 are temporarily lowered slowly, When the value is increased, it is determined that the sunrise and the sunset do not occur so that no beep is generated.

The power generated normally from the first and second solar panel plates 80 and 81 is output as the commercial power via the connection panel and the inverter. When the commercial power direction is abnormal during the process, Through the sensor units 5 and 6 and transmits the sensed signal value to the control device 85. When the sensed signal is inputted, the transmitted control device 85 performs calculation processing according to the set program, A signal is transmitted to the sound generating device such as a speaker to inform the user of a warning sound.

As described above, the present invention generates a signal sound when the power is abnormally generated from the solar cell, and when the output power passing through the inverter does not flow in the commercial power direction even when the power is normally generated, By providing a connection class that informs the user,

If a user has trouble during use, the contractor can immediately make an A / S request to the contractor. The contractor can identify the problem and inform the user of the problem on the phone so that the contractor can solve the problem. There is an advantage that both sides can help because it can reduce the waste of time according to the business trip and the user does not spend the travel cost.

Here, as will be described later in detail, when the solar radiation amount is blocked by an obstacle to any one of the first solar panel second solar panel, the power values detected from the first and second detection sensor units are divided into the first group and the second group Significant differences arise, and if this problem occurs, the user will be notified by a sound.

When the sound is generated, the customer calls the contractor, and the contractor asks the user to remove the obstacles existing in the first and second solar panels when the trouble reception is made.

Then, if the amount of power generated in the first group and the second group is equal to each other, the sound will be stopped. However, if the sound continues even if the obstacle is removed, the constructor requests the user to check the breaker installed between the inverter and commercial power.

If such a problem occurs, a device for informing the outside is installed, so that the problem can be solved conveniently and promptly.

At sunrise and sunset, the amount of power imposed on the first group and the second group is significantly different due to the obstacles blocking the solar radiation around the first and second solar panels (the surrounding tree branches, etc.).

Considering this case, the first and second detection sensor units 5 and 6 for sensing the power values of the first group and the second group at sunrise or sunset ignore the detection value even if the mission is performed Can be controlled according to the control signal).

The above-mentioned effects are further clarified in detail.

There is a first input terminal 10 through which a first solar panel 80 and a first solar panel 80 of a group are supplied with electric power and the electric power output from the first input terminal 10 is input A first group 100 having a first diode 12 for receiving and outputting power output from the first circuit breaker 11 and a fuse and a circuit breaker

A second group 200 having a second diode 22 for receiving and outputting power output from the second circuit breaker 21,

Here, the convenience of explanation is explained as the first group and the second group, but such a group can be composed of a plurality (in the third, fourth, fifth and sixth groups).

And a collective output terminal (60) for collecting the power output to the second group (200);

An inverter 300 for receiving and outputting power output from the combined output terminal;

And outputs it to the commercial power (400) via the inverter (300).

Hereinafter, the embodiment will be briefly described as a conventional configuration.

The power generated by the first solar panel 80 is output to the first circuit breaker 11 via the first input terminal 10 accommodated in the connection panel 500 and the power supplied to the first circuit breaker 11 To the first diode (12).

Such a group corresponds to the first group 100.

The power generated by the second solar panel 81 is output to the second circuit breaker 21 through the second input terminal 20 accommodated in the connection circuit 500, The power is output to the second diode 22 again.

Such a group corresponds to the second group 200.

To the inverter 300 via one output terminal 60 to collect the electric power inputted to the first group 100 and the electric power inputted to the second group 200 and input to the inverter 300 Converted to AC power, and output to commercial power (400).

Hereinafter, the technology corresponding to the present invention will be described.

Are connected to the power wiring line 3 'corresponding to the first group 100 and the power wiring line 4' corresponding to the second group 200 to detect the power value, Detection sensor units (5, 6);

The control unit 85 is connected to the first and second detection sensor units 5 and 6,

The control device 85 processes a power value flowing in the first group 100 and a power value flowing in the second group 200 and outputs a signal sound to notify the user when power values of the first group 100 and the second group 200 differ significantly .

An embodiment of such a configuration will be described.

The first group 100 and the second group 200 are connected to the first solar panel 80 and the second solar panel 81 when the snow is heavy on the first solar panel 80 and the second solar panel 81, Power is not input (slight power is input).

If this happens for about 10 hours, the user will be notified of the incapability of power generation by signaling or emitting light.

When the user removes the snow accumulated in the first solar panel 80 and the second solar panel 81 or if the snow is melted by the irradiation amount, power is normally generated. Therefore, the control device 85 controls the first and second detection sensor units 5 , 6) to block the current applied as a signal.

Hereinafter, a case will be described in which a problem occurs in power generation due to an obstacle (shade, yellow dust, breakage, etc.) in any one of the first and second solar solar panels 80 and 81.

For example, solar radiation is blocked by shade or other obstacles caused by wood on the first solar panel 80, and power values flowing in the first group 100 and the second group 200 are significantly different .

If this case continues for more than the set time, a luminescent or beeping tone is generated to notify the user of the problem.

When the user then removes the obstacle, the first solar panel 80 and the second solar panel 81 are normally powered, as described above, so that the control device 85 and the first and second detection sensor units 5 , 6) to block the current applied as a signal.

In the power sensing, the control device 85 senses a current through the first and second sensing sensor units 5 and 6, and cuts off power that is applied or applied to the signal.

The following shall be notified to the user as follows when the whole circuit breaker (including the fuse) in the connection panel is shut down.

Power is not instantaneously flowed into the inverter 300 and the commercial power 400 when the entire circuit breaker configured in the connection block 500 is shut off.

The control device 85, which detects the instantaneous power that is intercepted through the first and second detection sensor units 5 and 6 and computes the sensed value, notifies the user of the detected sound according to the set program.

Here, the control device 85 receives electric power from the first and second solar panel plates 80 and 81 by connecting electric wires between the connection panel 500 and the first and second solar panel plates 80 and 81 .

The following describes the process of generating a sound when there is an abnormality in commercial power.

The power normally generated from the first and second solar panel plates 80 and 81 is output as commercial power via the connection panel and the inverter. If the commercial power direction is abnormal during this output process, for example, It is not outputted to the commercial power side at this time. At this time, the operation state of the circuit breaker, that is, the state in which the current flow is interrupted is sensed through the first and second sensing sensor units 5, 6 sensing current flow, and the sensed signal value is transmitted to the control device 85 do. The control device 85, which monitors the breaker operation signal from the first and second detection sensor units 5 and 6, performs a calculation process according to the set program when the detected signal is inputted, A signal is transmitted to a sound generating device such as a speaker to inform the user of a warning sound.

next We want to detect power production at sunrise and sunset time and take action accordingly.

The control device 85 controls the power wiring line 3 'corresponding to the first group 100 and the power wiring line 4' corresponding to the second group 200 at a time corresponding to sunrise and sunset Data is inputted to the control device 85 so that a signal sound notifying the user does not occur even if a significant difference occurs in the flowing power value.

An embodiment of the above configuration will be described.

In the sunrise and sunset, the amount of solar radiation is blocked by the first and second solar panel plates 80 and 81 by various obstacles (surrounding trees, surrounding buildings, etc.) It becomes impossible to predict.

In this case, the amount of electric power produced by the first solar panel 80 and the second solar panel 81 may be remarkably irregular, so that the generation of a beep is omitted.

Further, at sunrise and sunset, for example, shade may temporarily be formed by the trees on both the first solar panel 80 and the second solar panel 81, or only the first solar panel 80 may be temporarily A shade can be formed.

In this case, the power input to the first group 100 and the second group 200 is significantly different. If a sound occurs until this time, the user turns off the purchase of the product.

At sunrise and sunset, the shade is slowly formed on the first and second solar panels 80 and 81, so the power is also slowly lowered (the same is true when clouds pass).

The slowly lowered power is continuously sensed through the first and second sensing sensor units 5 and 6, so that the sound is not generated when the data is slowly lowered.

However, when the shade is formed for a long period of time (about 10 hours or more), it is determined that the snow is going to fall down, or it is determined that there are other obstacles.

As described above, if the technical composition of the present invention is utilized, it is economically advantageous to save cost.
