Title: Mounted transformer for underground power line
Inventor: LEE SONG YEON
IPC: G07C9/00
Filed: 2021-05-21
Granted: 2021-07-23
Abstract: The present invention relates to a ground transformer for underground power lines. According to the present invention, the ground transformed is configured to determine whether an abnormal situation has occurred inside the ground transformer on the basis of environmental information inside the ground transformer obtained from detection sensors installed inside the ground transformer to transmit a determination result to an operator terminal and transmit state information of the ground transformer according to power consumption and overload to the operator terminal. The operator terminal is implemented as a smart phone and has a built-in electronic key capable of automatically opening and closing a door of the ground transformer and the electronic key is activated on the basis of user authentication through a biometric sensor of the smartphone. When the operator terminal in an activated state of the electronic key approaches the ground transformer within a specific distance, the ground transformer automatically opens the door. Accordingly, the present invention provides an advantage of reinforcing security to prevent non-operators from operating the ground transformer while facilitating opening/closing of the ground transformer.

Abstract: The present invention relates to a hanger for goods, used to place a bag, a tool and kitchen utensils on a rod and, more specifically, to a hanger for goods, comprising an upper hook hung on a rod and a lower hook for hanging goods, wherein the upper and lower hooks having a structure twisted by a predetermined angle lead a plurality of goods to be aligned in a longitudinal direction of the rod when placed, thereby making normal the alignment state of the goods and improving the use of space. The hanger for goods comprises an upper hook hung on a rod (P) and a lower hook for hanging various goods, wherein the upper and lower hooks are coupled to each other by coupling between the upper and lower bodies coupled to ends thereof, while in a state in which the upper and lower bodies are firmly coupled, the upper and lower hooks are located to be twisted by a predetermined angle instead of being located on the same plane, a through hole for passing a straight part of the lower hook is provided in the lower part of the lower body, a female screw part is formed on the inner circumferential surface thereof and the upper part thereof is open, a through hole for passing a straight part of the upper hook is provided in the upper body, a male screw part engaged with the female screw part is provided on the outer circumferential surface thereof, a protrusion protrudes from the upper end thereof in a radial direction, the straight parts of the upper and lower hooks are inserted into the upper and lower bodies, and then, a head part is formed at the upper end of the inserted side such that separation from the through holes can be prevented, and, in at least one of the straight parts of the upper and lower hooks inserted in the upper and lower bodies, a head part is formed after the insertion of a spring, thereby causing the head parts of the upper and lower hooks to be compressed by an elastic force of the spring.
