Branch breaker block for low voltage switchgear {Branching / blocking block for a low voltage distributing board}

The present invention relates to a branch breaker block employed in a low voltage switchgear, and more particularly, by allowing the input points of the simple terminal blocks to maintain a one-to-one correspondence at the same position as the output points of the branch breakers, the bus-bar is It relates to a branch breaker block for a low voltage switchgear which can be substituted for electric wires so that it can be easily used as "means for electrically connecting simple terminal blocks and branch breakers".

In general, a low voltage switchboard is an electrical device that distributes low voltage electricity drawn from a transformer to each load through a series of software.

As shown in FIG. 1 and FIG. 2, the low voltage switchboard 100 according to the related art includes a housing 101 in which a series of storage spaces are defined, a main breaker 10 disposed in the housing 101, and a main breaker 10. , A combination of a plurality of branch breakers 20 electrically connected to the main breaker 10.

In this case, the main circuit breaker 10 receives power transmitted from an external, for example, a transformer (not shown) through, for example, a first bus-bar 11, and then opens and closes the power through a plurality of open / close contacts. In addition, when an abnormality such as an overload, disconnection, or the like occurs, the power is automatically cut off from the transformer. The branch circuit breakers 20 are electrically connected to the main circuit breaker 10, and the main circuit breaker 10 is disconnected. After receiving power from), it selects and transmits power to each load (not shown). In this case, the power output from the main breaker 10 is transferred to the bus bus bar 13 via the second bus bar 12, and the power passing through the bus bus bar 13 is transferred to this bus bus. Via branch bus-bars 14 which are each electrically connected to bars 13, to respective branch breakers 20.

At this time, the second bus bar 12 and the bus bus bar 13 are electrically connected and fixed to each other through the connecting screw 16, and the bus bus bar 13 and the branch bus bar 14 are The connection bus 17 is electrically connected and fixed to each other, and the branch bus bar 14 and each branch breaker 20 are electrically connected and fixed to each other through the connection screw 15.

Meanwhile, as shown in FIG. 2, the power output from each branch breaker 20 forms a transmission path via the plurality of wires 21 and the simple terminal block 30, and in this state, each The loads receive power output from the branch breakers 20 through the simple terminal blocks 30. In this case, the wires 21 are electrically connected to and fixed to the respective branch breakers 20 through the connection screw 22 in a state where the wires 21 are fitted to the connector 23. In this state, the respective branch breakers 20 are connected. Electric power output from the electric field is transferred to the simple terminal block 30 side.

In this case, as shown in Figures 3 and 4, the preceding simple terminal block 30 forms a structure in which the branch circuit breaker side terminal block 31 and the load side terminal block 32 are combined into one body. In this case, the branch circuit breaker-side terminal block 31 is electrically connected and fixed through the connecting screw 33 in the state where the aforementioned wires 21 are fitted to the connector 23, and output from the branch breaker 20 side. The load is delivered to the terminal block 32, each load is electrically connected through the lead-out line, and receives the power output from the wires (21).

In the low-voltage switchboard 100 according to the related art having such a configuration, since the above-described simple terminal blocks 30 are generally manufactured, sold, and distributed separately from the preceding branch breakers 20, the branch breaker ( Regardless of 20), it is inevitably designed and manufactured, and in this case, each of the simple terminal blocks 30 is inevitably different from the branch breakers 20 in size.

As such, when the sizes of the respective simple terminal blocks 30 and the branch breakers 20 are different from each other, one-to-one position adjustment between the input points of the simple terminal blocks 30 and the output points of the branch breakers 20 is very difficult. As a result, the manager who manages the low-voltage switchboard 100 cannot use a fixed electrical connection tool as a "means for electrically connecting the simple terminal blocks and branch breakers," for example, such as a bus bar. In this case, the manager side can only use the flexible electrical connection tool, for example, the wire 21 described above, as the "electric connection means between the simple terminal blocks and the branch breakers".

However, since the installation process of the above-described wire 21 is very complicated compared to the bus bar, under the conventional system, the branch breaker 20 and the simple terminal block 30 can be installed on the manager side unless a separate measure is taken. In electrical connection, you have to take a lot of difficulties.

In addition, as described above, in order to electrically connect the electric wire 21 to each of the simple terminal blocks 30 and the branch switches 20, a separate connector 23 is required. On the side, in order to electrically connect the branch breaker 20 and the simple terminal block 30, there is no choice but to bear the problem of unnecessary waste.

Furthermore, since the above-described wires 21 differ from each other in the lead-out lines on the load side and their electrical connection structure, under the conventional system, the simple terminal blocks 30 and the branch breaker-side terminal blocks 31, as described above, are different from each other. In addition, the dual structure divided into the load-side terminal block 32 is inevitably taken, and thus, the size thereof becomes inevitably large, and according to such size increase, the unit price becomes inevitably high. Unless action is taken, under the conventional system, the manager is forced to bear unnecessary expense.

Accordingly, an object of the present invention is to consider the size of branch breakers in advance when manufacturing simple terminal blocks, so that each of the simple terminal blocks can maintain the same size as the branch breaker, whereby the input points of the simple terminal blocks By maintaining a one-to-one correspondence at the same location as the output points, the bus-bar replaces conventional wires, inducing them to be easily used as "means for electrically connecting simple terminal blocks and branch breakers."

Another object of the present invention is to allow the simple terminal blocks and the branch breakers to be electrically connected through a plurality of bus bars to form a completed unit block, so that the use of wires can be stably excluded. By doing so, "difficulty in connecting the simple terminal blocks and branch breakers with wires", "the problem of unnecessary waste of use of the connector" and the like can be easily solved.

It is still another object of the present invention to replace conventional wires with bus-bars similar to the lead-out lines on each load side and their electrical connection structure, thereby inducing the structure of the simple terminal blocks, thereby increasing the size of the simple terminal blocks. Minimize unnecessary cost waste.

Still other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

In order to achieve the above object, in the present invention, through a branch bus-bar electrically connected to a series of bus bus-bars, the main circuit is electrically connected to the main breaker, and after receiving power from the main breaker, A plurality of branch breakers for selecting and transmitting the loads to the loads, a plurality of draw bus-bars which are electrically fixed one-to-one with the power output points of the branch breakers and are drawn in line from the power output points; While maintaining the same size as the breakers, they are spaced apart and fixed at a certain distance from the corresponding branch breakers, electrically connected to the drawing bus bars, and one-to-one fixing the drawing line of the loads at the connection points of each drawing bus bars. With a combination of simple terminal blocks that guide the power output from the branch breakers to be selected and delivered to the loads. A branch breaker block for a low voltage switchgear is provided.

Hereinafter, with reference to the accompanying drawings, it will be described in more detail the branch circuit breaker block for low voltage switchboard according to the present invention.

As shown in FIG. 5, the low-voltage switchboard 200 employing the present invention is largely a combination of a housing 201 in which a series of storage spaces are defined, and a main breaker 202 disposed in the housing 201. Is done.

At this time, the main circuit breaker 202 receives the power transmitted from the outside, for example, the transformer through, for example, the first bus-bar 203, and then opens and closes it through a plurality of open and close contacts, and overload, disconnection, etc. When an error occurs, it automatically cuts off the power transmitted from the transformer.

Here, the power output from the main breaker 202 is transferred to the bus bus bar 206 via the second bus bar 204, in which case the bus bus bar 206 is, for example, a main breaker. Stretching long along the longitudinal axis of 202, it provides a set of infrastructures that allow the power output from the main breaker 202 to be reliably delivered to the loads 300 disposed outside the enclosure. At this time, the second bus bar 204 and the bus bus bar 206 are electrically connected and fixed to each other through the connection screw 205.

Here, as shown in FIG. 6, the branch breaker block 210 forming the gist of the present invention is largely via a branch bus bar 207 electrically connected to the previous bus bus bar 206. A plurality of branch breakers 211 electrically connected to the main breaker 202 and simple terminal blocks 213 spaced apart and fixed from the branch breakers 211 by a predetermined distance are formed. In this case, the branch bus bar 207 and the bus bus bar 206 are electrically connected and fixed to each other through the connecting screw 208.

In this state, the branch breakers 211 receive power transmitted from the main breaker 202 and then select and transmit the power to the loads 300.

At this time, in the present invention, unlike the prior art, when manufacturing the simple terminal block 213, by considering the size of the branch breaker 211 in advance, the size of the simple terminal block 213, for example, L2 is the size of each branch breaker (211) For example, it is possible to maintain the same size as L1.

As such, when the sizes of the simple terminal blocks 213 can maintain the same size as the sizes of the respective branch breakers 211, the connection grooves 213c of the simple terminal blocks 213 described later are output points of the branch breakers 211. At the same position as the ones P, it is possible to form a one-to-one correspondence, and consequently, under the system of the present invention, "means for electrically connecting the simple terminal blocks and the branch breakers" is conventional, as shown in the figure. It can be easily replaced by the withdrawal bus-bar 212 at the wire of. In this case, the draw bus-bars 212 form a structure that is drawn out from the corresponding power output points P in a state of being electrically fixed to the power output points P of the branch breakers 211. .

As such, by implementing the present invention, the simple terminal blocks 212 and the branch breakers 211 may be electrically connected to each other through a plurality of outgoing bus bars 212 to form a unit block of a completed form. If, in the low-voltage switchboard 200, the use of the wire can be stably excluded, after all, the administrator who manages the switchboard is "difficulty in connecting the simple terminal blocks and branch breakers to the wire", "connector's It can easily solve the problem of unnecessary waste of use ".

At this time, as shown in the figure, each of the simple terminal block 213 employed in the present invention is a body 213a, a plurality of partitions 213b and are arranged on the body 213a, and the partition 213b ) And a combination of one-to-one corresponding connection grooves 213c at the same position as the power output points P of the branch breakers 211 described above. In this case, the aforementioned draw-out bus bars 212 are withdrawn from the power output points P of the branch breakers 211 and are seated in the connection grooves 213c and through the connection screw 213d. , Forms a structure in which the contact grooves 213c are electrically contacted and fixed.

In the conventional case, under the conventional system, the simple terminal blocks are connected to each branch breaker through the wires on each load side, for example, each load-side bus-bar and its electrical connection structure through different wires. There was no choice but to take a dual structure, which was divided into a branch breaker side terminal block and a load side terminal block.

However, in the present invention, the simple terminal blocks 213 are each of the branch breakers 211 through the outgoing bus-bars 212 similar in electrical connection structure to the outgoing lines 301 on each load 300 side. In the system of the present invention, the simple terminal blocks 213 are not connected to each other, so that the common connection of the drawing bus-bars 212 and the drawing lines 301 is provided through the connecting grooves 213c. It is possible to provide a fixed point, which, in turn, makes it easy to obtain the advantage of simplifying the structure.

As such, when the structure of the simple terminal blocks 213 is simplified, an administrator who manages the switchboard 200 may reduce unnecessary cost waste due to the size increase of the simple terminal blocks 213.

In the low voltage switchgear branch breaker block 210 of the present invention having the above-described configuration, the power output from the transformer diverges through the main breaker 202, the bus bus bar 206, the branch bus bar 207, and the like. When delivered to the breaker 211, the branch breaker 211 immediately selects and transmits the corresponding power output from the main breaker 202 to the draw bus bars 212, and the draw bus bars 211. They transfer this power to the lead-out line 301 of each load 300 electrically connected to itself through the simple terminal block 213, and eventually, the power output from the main breaker 202 is transferred to each load 300 Can be properly branched and supplied.

As described in detail above, in the present invention, when manufacturing the simple terminal blocks, in consideration of the size of the branch breaker in advance, each of the simple terminal blocks to maintain the same size as the branch breaker, through which the input points of the simple terminal blocks By maintaining a one-to-one correspondence at the same location as the output points of the branch breakers, the bus-bars replace conventional wires, inducing them to be easily used as "means for electrically connecting simple terminal blocks and branch breakers" do.

By the implementation of the present invention, when the simple terminal blocks and the branch breakers are electrically connected through a plurality of bus bars to form a unit block of a completed form, in the low voltage switchboard, the use of electric wires is stable. As a result, the administrator who manages the switchboard can easily solve the "difficulty in connecting the simple terminal blocks and branch breakers with wires" and "the problem of unnecessary waste of using connectors". .

In this case, since the above-described drawing bus-bars have similar electrical connection structures with the drawing lines on each load side, by the implementation of the present invention, the simple terminal blocks can be connected to the respective branch breakers through the drawing bus-bars. If possible, each of the simple terminal blocks can provide a common fixed point of the withdrawal bus-bars and withdrawal lines, through their connecting grooves, without the need for a separate double structure. It is easy to obtain the advantage of minimizing unnecessary waste of cost.

This invention has an overall useful effect in a low voltage switchgear of various models requiring a branch breaker.

And, in the foregoing, although specific embodiments of the present invention have been described and illustrated, it is obvious that the present invention may be variously modified and implemented by those skilled in the art.
