Abstract
Description
BACKGROUND OF THE
Generally, an APU (Automatic Power Transfer Unit (APU); or ATU, ATS) is installed in a household distribution board that distributes electricity to factories, buildings, large residential areas, and public houses and buildings In case of interruption of normal (commercial) power supply due to power outage or accident, it is automatically switched to emergency power source to minimize inconvenience by operating necessary equipment (load of emergency light, security equipment, boiler etc.) And then supplies commercial power to the household to supply power continuously.
APU is equipped with a circuit breaker inside and outside the emergency power supply line, and a load (emergency) load is connected to the power output unit so that crime prevention and fire function, visitor identification service, emergency call service, It is an automatic power switching device that enables functions such as constant / emergency power supply to be maintained. Here, the earth leakage breaker may be built in or enclosed in the APU, and may be classified into a horizontal or vertical type product.
FIG. 1 is a plan view of an APU according to the prior art, and FIG. 2 shows a state where a main body and an earth leakage breaker are connected in an APU according to a related art. Fig. 3 is a bottom view of the earth leakage breaker in Fig. 2. Fig.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an assembling structure of an APU for preventing damage to a cable connected to an earth leakage breaker when assembled.
An assembly structure of an APU according to an embodiment of the present invention includes an earth leakage breaker having an emergency power connection part at one side thereof; An APU main body in which a receiving portion of the earth leakage breaker is formed at a portion thereof and a general power source unit is provided; And a cable for connecting the emergency power connection part and the general power supply part, wherein a first fastening part detachable by sliding or fitting is formed on one side of the accommodation part, and a part of the earth leakage breaker is slidably inserted into the first fastening part, Or a second fastening portion capable of being engaged by a fitting method is formed.
Here, the first fastening portion may be a rectangular parallelepiped protrusion, and the second fastening portion may be a groove corresponding to the protrusion.
Further, a screw hole is formed at the other side of the receiving portion.
In addition, the first fastening part may be formed as a '-shaped protrusion, and the second fastening part may be formed as an' b '-shaped protrusion.
In addition, the second fastening portion is formed as a straight groove.
In addition, a cable receiving part for receiving the cable is formed at one side of the receiving part, and a fixing part for downwardly folding the end part of the wall constituting the cable receiving part is formed in an annular shape, and an annular protrusion And can be engaged with the fixing portion.
According to the assembly structure of the APU according to the embodiment of the present invention, the bolt connection is eliminated in the portion where the cable is formed, and the fastening means by the slimming method is provided to prevent the coating of the cable from being peeled off.
