Automatic Power Supply Transfer Switches

The present invention relates to a power supply automatic switching device, and more specifically, the energizing unit, the driving unit and the electric component is sequentially coupled, the combination of the components of the electric component is made of fitting, simplifying the work process when replacing parts and repair The present invention relates to a power supply automatic switching device in consideration of the operator's convenience.

In general, when the power supply is cut off from a substation in a workplace or a building equipped with its own power generation equipment, the automatic switching device automatically switches the indoor wiring terminal to the generator side so that the power can be continuously supplied. If it is made normally, it is automatically switched again to supply power to the substation side.

Referring to FIG. 1, the conventional power supply automatic switching device 100 includes a power supply unit 110 in which each phase (R, S, T, N) is displayed to the outside, a driving unit 120 in which magnetic force is generated, and wirings. The electric part 130 made up is divided into three parts and is assembled by being assembled in the order of the energizing part 110, the electric part 130, and the driving part 120. As the contact point with the wiring terminal is changed, continuous power supply is made smoothly in products requiring power.

However, the automatic power supply switching device 100 configured as described above is frequently disassembled and coupled to the electric parts 130 due to the continuous management of the electric parts 130 for the post-management of failure or wiring due to a short circuit or an electric leakage accident. Although this is done, a process of disassembling the entire power automatic switching device 100, that is, three parts, is required for disassembly of the electric component 130 positioned and mounted between the energizing unit 110 and the driving unit 120. Due to the hassle of dismantling and fastening a large number of coupling members such as bolts during disassembly and coupling, there were difficulties in manufacturability and assembly.

The present invention was devised in view of the above problems, while the electric parts are built-in and mounted in the driving unit of the automatic power switch, they are generally fastened in the order of the electric parts, the driving unit, the energizing unit, and replaced by a simple fitting of a plurality of bolt couplings. It is an object of the present invention to provide a power supply automatic switching device that improves productivity and workability while simplifying the structure, making it easy to replace and repair parts, and providing convenience to the operator for disassembly and coupling.

The present invention for achieving the above object, in the power supply automatic switching device consisting of a power supply unit, a drive unit and an electric power unit for selectively loading the substation side power supply and the power generator side power supply, one side of the power supply unit is the power input The lower plate and the upper plate are coupled to each other, and the driving unit and the electric unit are fixed and seated in order in the internal space formed by the coupling. The driving unit includes a fixed plate fixedly mounted with a solenoid and a coupling plate fitted to the fixed plate. It is located at both sides.

A coupling member penetrating the mounting hole of the fixed plate and a magnet inserted into and fixed to the solenoid are combined to mount the solenoid to the fixed plate.

The fixing plate and the coupling plate are coupled to each other by fitting the plurality of fixing holes formed in the fixing plate and the fixing groove formed in the coupling piece protruding from the coupling plate.

Hereinafter, with reference to the accompanying drawings an automatic power supply switching device according to a preferred embodiment of the present invention will be described in detail.

As shown in Figures 2 to 4, the power supply automatic switching device 10 of the present invention is the lower plate 31 and the one side of the current-carrying portion 20 that each terminal (R, S, T, N) is included; The upper plate 32 is coupled and mounted, and the driving unit 30 and the electrical component unit 50 are sequentially connected to the circuit by being wired while being sequentially positioned in the inner space formed by the lower plate 31 and the upper plate 32. Is seated fixed.

Solenoids 33 and 33 'are positioned at both sides of the driving unit 30, and the solenoids 33 and 33' are installed to selectively move the operating device 40 which is interlocked with the solenoids 33 and 33 '. ′) Is positioned between the fixed plate 35 and the engaging plate 39, and the mounting hole 34 ′ formed at approximately the center of the magnet 33a and the fixed plate 35 inserted into the solenoids 33 and 33 ′. It is fixedly mounted by a coupling member 34a penetrating through the insertion device 38, and the insertion hole 38 formed in the coupling plate 39 according to the electromagnetic force generated by the selective energization of the solenoids 33 and 33 '. A pair of magnetic pieces 41 which are moved while passing through them are spaced apart from each other, and the application display panel 42 is refracted such that both ends thereof are attached to the magnetic pieces 41 and the center part thereof is close to the upper surface of the upper plate 32. It is installed, the movement force of the magnetic force 41 The spring 44 is mounted on the second lever 45 so as to double, and the pair of first levers 43 protrude from the energization part 20 so that the movement of the magnetic piece 41 is free.
