Description

The bypass diode integrated parallel connector < RTI ID = 0.0 >

The present invention relates to a bypass diode-integrated parallel connector, and more particularly, to a bypass diode-integrated parallel connector in which a bypass diode is integrally combined with a power cable assembly extending from a solar panel .

Recently, the use of photovoltaic power generation equipment capable of generating electric power using solar energy has become increasingly popular.

Solar cells using solar energy are not used as fossil fuels such as coal or petroleum, and they are attracting attention as a new alternative energy source in the future by using sunlight which is pollution-free and infinite energy. Nowadays, Buildings, and automobiles.

Generally, photovoltaic power generation is a technique of directly producing electricity using photovoltaic (PV).

The solar cell uses a semiconductor device that converts light energy into electrical energy using a photoelectric effect, and a plurality of solar cells are connected in series or in parallel to generate a voltage and a current required by a user.

On the other hand, even if only a small part of the solar module is covered with shadows, the output of the solar module as a whole is greatly reduced.

This is because the solar module is constructed by connecting each solar cell in series, so that current is passed through the solar cell having no output because it is shaded by shadows, causing the output to drop.

For example, in a photovoltaic module consisting of 54 solar cells, if only one solar cell is completely obscured by leaves or the like, the output current of the photovoltaic module may drop to near zero.

In order to prevent power loss due to the shadows, a bypass diode is generally installed in the solar module.

The bypass diode is connected in parallel to a solar cell or a solar cell group so that current flows by bypassing a solar cell or a solar cell group whose output is reduced due to shadow, The output of the solar module can be maintained by restricting the solar cell or the solar cell group covered by the shadow only.

The bypass diode is generally installed in a junction box or connected to a cable extended from a solar cell or a group of solar cells. Such a connection scheme is used when a solar cell module or a solar cell group The bypass diode must be soldered to the cable extended from the cable, and then the soldered portion must be wound around the electrical tape or the shrink tube. This may complicate the operation, and the soldering portion between the bypass diode and the cable may be broken.

Also, since the bypass diode connection method has a weak waterproof function, rainwater can flow into the connection portion between the cable and the diode, and the electricity output from the solar module due to the inflow of rainwater can be short- ) And a minus pole (-) are brought into contact with each other to generate an overcurrent and lead to an electric fire.

On the other hand, in the prior art of the present invention, a "solar cell module" of the patent registration number "10-1189373" was filed and registered. The solar cell module includes a solar cell panel formed of a plurality of solar cells, ; An external connection cable connected to the bus bar; And a case having a space for accommodating the solar cell panel and the cable for external connection, wherein the case is formed of a first space for accommodating the solar cell panel and a second space for accommodating the cable for external connection, A partition is formed in the case so as to partition the first space and the second space, a housing part for housing the bypass diode is formed inside the case having the second space formed therein, and the temperature of the bypass diode is set in the housing part And a temperature detecting sensor for measuring the temperature of the sample.
