The present invention is applied to a switchgear device that receives power supplied by a power company and distributes power to each load of a customer, and is used to electrically and mechanically connect each busbar and a circuit breaker of a main busbar. Bus bar connection device of the switchgear breaker, more specifically, the front of the main body of the circuit breaker and the electrical connection terminal is provided with a multi-row binding guide request to expose the wiring breaker is inserted into the back It is equipped with a circuit breaker insertion device to be fixed, and the electrical connection between the main busbar and the circuit breaker is possible, so that a non-skilled person can be quickly and easily connected and removed with one touch without the need for a separate process for assembling. In addition to work, handling and disconnection of circuit breakers can be facilitated. It is one to provide the simplicity of the structure and appearance after setting.

In general, a building, a factory, or an apartment is provided with a number and a power distribution device that receive electricity from a power company and distribute the power to each customer's load.

These water and power distribution devices are intended to be supplied with high voltage or special high voltage to reduce the pressure to suit the purpose and to be sent to each load of the customer, and the cabinet of a predetermined size designed in consideration of safety against electric shock and fire, and the interior of the cabinet. Various breakers and protection equipment such as switchgear, transformer, main breaker, condenser, wiring breaker, power fuse, fatigue device, and various relay equipment such as current transformer, power meter, video current transformer, ammeter, voltmeter are installed.

And these can be. The power distribution unit is composed of an extra high voltage transformer panel (LBS panel), a transformer transformer current base (MOF panel), an instrument transformer panel (PT panel), and an extra high breaking board (VCB panel) for receiving high or extra high voltage. It consists of a transformer board with a transformer, and a low voltage switchgear consisting of a low voltage blocking base and a power distribution board.

The low voltage switchgear distributes the low voltage electricity supplied from the transformer to each load through a series of devices and prevents the overcurrent from flowing, and supports various unit devices such as a circuit breaker or a protection relay and attaches these unit devices. And a collection of conductors (Busbar, Cable) for connecting and connecting the unit.

Low-voltage switchboards, on the other hand, are individually designed to suit the size and power consumption of the building. Therefore, low pressure switchboards are difficult to provide as a standardized product. Accordingly, in the conventional low voltage switchgear, the switchgear is designed to meet the electric power demand, and the main bus bar and the branch bus bar are contacted according to the design, and then the bus bar is cut, bent or holed and assembled. This not only complicates the manufacturing process, but also requires excessive time and money, and requires skilled professionals.

A typical low voltage switchgear is composed of a main circuit breaker installed in a predetermined cabinet, a plurality of circuit breakers electrically connected to the main circuit breaker, and a predetermined busbar system.

Here, the main breaker is to open and close the power supplied from the transformer, and to automatically cut off when an abnormality such as an overload, disconnection, etc., the wire breaker in the state electrically connected to the main breaker, the power delivered from the main breaker It serves to send to the load. The busbar system may be configured to electrically connect the main breaker and the circuit breaker, and a plurality of busbar busbars connected to the main circuit breaker and a busbar connection device of the circuit breaker for electrically connecting the circuit breaker and the busbar busbar. Is made of.

The present invention relates to a busbar connection device of the above circuit breaker, the busbar connection of the existing circuit breaker is connected to the main busbar 61, 61 'receiving power from the transformer at the input terminal as shown in FIG. The main bus bar 62 is vertically installed at the output end of the main breaker 60, and the plurality of branch bus bars 63 are installed in the main bus bar 62 in the orthogonal state in the horizontal direction. Distribution breakers 64 are respectively provided at ends of the branch busbars 63, and loads are connected to the output terminals of the circuit breakers 64, respectively.

In the busbar connection structure of the conventional circuit breaker, a plurality of branch busbars 63 installed in a horizontal direction are orthogonal to the main busbar 62 installed vertically, and wiring is provided at both ends of the branch busbar 63. Since the circuit breaker 64 is provided, in order to intersect the main busbar 52 and the branch busbar 63 and to selectively connect at a predetermined intersection, a fastening hole is formed in each intersection and the branch is formed. Bends should be formed at the contacts of the busbars 63. However, since the position of the intersection point of the main busbar 62 and the branch busbar 63 varies depending on the design of the switchboard, the busbar cannot be bent or holed in advance. Since the assembly process is complex and must be performed only by skilled professionals.

In addition, the connection means of the conventional circuit breaker as described above should be fastened and fixed to the main bus bar 62 to be connected to the branch bus bar 63 through a fixing bolt, and when the wiring breaker is replaced, the branch bus bar 63 is loosened by loosening the bolts. ), The work is quite complicated and cumbersome, and it takes a lot of time and manpower according to the fixing work, and the appearance is complicated because the branch busbar 63 is dizzyly exposed to the surface of the main busbar in an orthogonal state. There was a problem done.

In addition, since the circuit breaker 64 is not directly connected to the main bus bar 62 in an overlapping state, the circuit breaker 64 is positioned at both ends of the branch bus bar 63 spaced apart from the main bus bar 62, so that the main bus bar 62 is located. As the area occupied by the circuit breaker 64 increases, the size of the distributor is increased and space utilization is reduced.

The present invention has been devised to solve the problems caused by the existing structure as described above,

The purpose of the present invention is to electrically connect the main busbar and the circuit breaker, so that the unskilled person can quickly and easily connect and remove them with one touch without the need for a separate process. The convenience of handling can be achieved, and the appearance after connection is very simple, which improves aesthetics. By using the connecting device, the circuit breaker can be directly connected to the main busbar to connect the main busbar and the circuit breaker. It is to provide a busbar connection device of a switchgear breaker that can minimize and improve the space utilization in the enclosure,
