Abstract

The present invention relates to a one-touch coupling type busbar kit and, more particularly, to a one-touch coupling type busbar kit which allows a plurality of cross-positioned busbars used for conducting in a switchboard or distribution panel to be conveniently coupled to each other without the need for bolts and nuts, etc.

Description

One-touch combination busbar kit

The present invention relates to a one-touch coupling type busbar kit, and more specifically, one-touch to facilitate connection of a plurality of cross-batch type busbars used for energization in a switchboard or distribution panel without the need for bolts or nuts. It relates to a combined busbar kit.

In general, power supplied through a transmission system and a distribution system is divided into various power demands through a distribution panel and a distribution panel. (bus bar).

In the above-mentioned power distribution panel and distribution panel among power equipment, it is essential to consider the effect of eddy current and temperature rise when conducting large current. When a large current is energized through a bus bar, streaks occur due to the large current in the interior and enclosure of the switchboard or distribution panel, causing heat generation.

In particular, if the current flowing through the conductor changes in time, an eddy current flows to the surrounding metal adjacent to the conductor by the generated magnetic field, and additional streaks are generated. When the metal is a magnetic material, hysteresis occurs due to magnetization, and hysteresis loss occurs. When such a loss occurs in a power device, the life and efficiency of the device are seriously reduced. In addition, electrical stability must also be considered, as it may affect the system from a bus bar that conducts high voltage to an accident due to insulation breakdown.

As such, as the rated voltage and current increase due to the effects of electrical stability and heat generation, the volume of the enclosure of the switchboard or distribution panel tends to increase proportionally. Of course, if the volume of the enclosure and the separation distance between phases are increased, electrical stability and influence by heat can be reduced.

However, since the production cost and installation cost increase due to the recent trend of rising raw material prices, it is urgently required to shorten the production time and the working time, as well as to reduce the volume of the switchboard or distribution panel.

In relation to this, through Korean Patent Registration No. 10-0811374 and Korean Patent Registration No. 10-0890155, a flat washer and a tabbed fixing washer and an insulating material and a bolt can be used to closely connect and connect a bus bus bar without processing. In order to distribute power to the distribution panel, the bus bus bar connected to the bus bar and the charity bus bar can be easily and quickly connected, and a fastening method of the bus bar has been disclosed.

However, in the method of fastening the bus bar according to the prior art, the contact portion of the bus bus bar (vertical bus bar) and the bus bus bar (horizontal bus bar) arranged vertically and horizontally crosswise to connect the parking breaker and the branch breaker. Is bolted with a bolt and a nut, and the work is cumbersome and the work time has been delayed due to the performance of the bolting operation.

In addition, as described above, a contact point (connection part by a fixing screw) is formed at the intersection of the busbar and the busbar connected via a bolt as a medium, and the coupling force of the bolt connecting the contact may deteriorate after a long period of time. , In this case, there has been a problem such as fire caused by sparks and sparks, as well as a reduction in the power applied due to a decrease in the contact force at the contact point.

In the end, in addition to overcoming all the problems as described so far, the heat generated by the busbar occupies a significant portion of the causes of heat distribution in the switchboard or distribution panel, and the systematic and logical arrangement and connection (connection) of the busbar Research and development of technology is required.

The object of the present invention is to solve the above-mentioned problems, and the vertical bus bar and horizontal bus bar are positioned crosswise and vertically and horizontally, and the one-touch method is combined. A combination of an upper jig and a lower jig that achieves a structure, to provide a one-touch coupled bus bar kit that enables mutual contact and fixing of the vertical bus bar and the horizontal bus bar without the need for a binding member such as a bolt and a nut.

The object of the present invention is to solve the above-mentioned problems, and the vertical bus bar and horizontal bus bar are positioned crosswise and vertically and horizontally, and the one-touch method is combined. The combination of the upper jig and the lower jig to achieve the structure, the vertical bus bar and the horizontal bus bar can be mutually contacted and fixed without the need for a binding member such as a bolt and a nut. Or for the electrical connection of the parking breaker and branch breaker in the distribution panel, a plurality of vertical bus bars and horizontal bus bars that are arranged crosswise and longitudinally; An upper jig to which the pair of horizontal bus bars electrically connecting the two branch circuit breakers are assigned while passing through the longitudinal direction; And, while being mutually coupled to the upper jig, a plurality of vertical bus bars extending from the parking terminal intersecting the horizontal bus bars and contacting each of the horizontal bus bars are arranged for intrinsic reception at regular intervals. It is characterized by.

In addition, the horizontal bus bar, the first connection piece connected to any one of the pair of connection terminals provided on any one of the branch circuit breaker, and any one of the pair of connection terminals provided on any other branch circuit breaker Separately configured as a second connecting piece connected to one, the first connecting piece and the second connecting piece include contact pieces connected to both ends of a vertical bus bar which is bent downward from each tip facing each other and cross-placed on the lower side. do.

In addition, in the upper jig, a plurality of position protrusions are protruded downward at regular intervals of a lower surface facing the lower jig, and in the lower jig, a plurality of receiving grooves in which the vertical bus bars are respectively accommodated are along the longitudinal direction. It is formed at regular intervals, and a plurality of positioning grooves in which the position projections are correspondingly inserted are formed at the upper end between the receiving grooves.

Further, in the upper jig, a binding hook for mutual coupling with the lower jig is formed to extend downwardly from both front ends in the longitudinal direction, and in the lower jig, the binding hook is engaged when the upper jig is seated on the upper side. It is to provide a one-touch coupling type busbar kit in which the binding groove to be formed is further formed at each of both ends in the longitudinal direction.

As can be clearly seen from the above description, the one-touch combination busbar kit of the present invention, the cross arrangement of the vertical bus bar and the horizontal bus bar used to electrically connect the parking and branch breakers in the switchboard or distribution panel using the upper and lower jigs. Of course, it is easy to position, and the work by contacting and fixing between bus bars that are cross-placed horizontally and vertically without the need for fastening members such as bolts and nuts by achieving the mutual coupling structure of the upper and lower jigs by one-touch method It improves efficiency and reduces working time.

In addition, it is possible to reduce the processing cost by eliminating the need for hole processing for bolting of the contact portions of the bus bars by allowing the contact of the bus bars and maintaining the contact state according to the mutual coupling structure of the upper jig and the lower jig. Recycling is easy because there is no damage to the bars.

Along with this, the contact state between the bus bars is maintained for a long period of time due to the mutual coupling of the upper jig and the lower jig, and thus a problem of power failure and fire that may be caused by a decrease in contact force between bus bars due to the phenomenon that bolting becomes loose over a period of time. It is a very useful invention that shows several effects in terms of safety, such as is easily solved.
