One-touch combination busbar kit {ONE-TOUCH COMBINATION TYPE BUS BAR KIT}

The present invention relates to a one-touch connection type busbar kit, and more particularly, one-touch connection of a plurality of cross-arranged busbars used for electricity in a switchboard or distribution board without the need for bolts and nuts. It relates to a combined busbar kit.

In general, the power supplied through the transmission system and distribution system is divided into several power demanding parts through a switchboard and a distribution board, but the bus bar serves as a distribution of power. (bus bar).

Among power devices, it is essential to consider the effect of eddy currents and temperature rise when applying high currents in the aforementioned switchboards and distribution boards. When a large current is energized through the bus bar, heat loss occurs in the interior and enclosure of the switchboard or distribution panel due to the large current.

In particular, if the current flowing through the conductor changes over time, an eddy current flows in the surrounding metal adjacent to the conductor due to the generated magnetic field, and additional joint loss occurs. When the metal is a magnetic material, a hysteresis phenomenon occurs due to magnetization, and a hysteresis loss occurs. When these losses occur in power equipment, the life and efficiency of the equipment are seriously deteriorated. In addition, electrical stability must also be considered as it may affect the system in the event of an accident due to insulation breakdown in the busbar carrying high voltage.

In this way, as the rated voltage and current rise due to the effects of electrical stability and heat generation, the volume of the enclosure of the switchboard or distribution board tends to increase proportionally. Of course, if the volume of the enclosure and the distance between the phases are increased, the electrical stability and the effect of heat can be reduced.

However, as the production cost and the installation cost increase according to the recent trend of raw material price increase, it is urgent to reduce the volume of the switchboard or distribution board, as well as to shorten the production time and working time.

In relation to this, through Korean Patent No. 10-0811374 and Korean Patent No. 10-0890155, a flat washer, a tapped fixing washer, an insulating material, and a bolt can be used to closely connect and connect the bus bar without processing. Thus, a method of fastening a bus bar has been disclosed so that the bus bar and the own bus bar, which are connected to distribute power to the distribution board, can be connected simply and quickly, as well as shortening the working time.

However, the method of fastening the bus bar according to the prior art is the contact portion between the bus bar (vertical bus bar) and the own bus bar (horizontal bus bar) intersecting vertically and horizontally to connect the parking circuit breaker and the branch circuit breaker. Bolting is done with bolts and nuts, and the work has been cumbersome and time has to be delayed.

In addition, a contact (connection by a fixing screw) is formed at the intersection of the bus bar and the own bus bar connected via a bolt as described above, and the bonding force of the bolt connecting the contact may decrease after a long period of time. In this case, there have been problems such as a fire due to sparks, as well as poor energization reduced by a reduction in contact force at the contact point.

In the end, in addition to overcoming all the problems as described so far, the heat generated from the bus bar accounts for a large part of the cause of heat generation in the switchboard or distribution panel.Therefore, it is related to the systematic and logical arrangement and connection (connection) of the busbar. Technology research and development is required.
