Description

Safety device to prevent cross-contact arcs between wires when installing electricity meters The present invention relates to a safety device. More specifically, the present invention relates to a safety device for preventing arc contact between wires when installing an electric power meter. Korean Utility Model Publication No. 20-0340170 (published January 1, 2004) discloses an example of an electric power meter. Referring to the aforementioned publication, in order to connect a wire to the electric power meter, a worker must push the end of a stripped wire vertically into a hole formed on the lower surface of the main body. Generally, electric power meter installation is performed while the wires are live, and since the meter has multiple holes formed at close intervals, an arc may occur due to contact with an adjacent wire during the process of inserting or removing the stripped wire end from the hole. Arcs act as a major cause of safety accidents and electric power meter failures. FIG. 1 is a perspective view of a safety device for preventing arc contact between wires when installing a power meter according to the first embodiment of the present invention. Figure 2 is a magnified view of section 'A' of Figure 1. FIG. 3 is a diagram showing the usage state of a safety device for preventing arc contact between wires when installing a power meter according to the first embodiment. Figure 4 shows an improved safety device for preventing arc contact between wires when installing a power meter according to the first embodiment of the present invention. FIG. 5 is a perspective view of a safety device for preventing arc contact between wires when installing a power meter according to a second embodiment of the present invention. FIG. 6 is a perspective view of a safety device for preventing arc contact between wires when installing a power meter according to a third embodiment of the present invention. Figure 7 is a magnified view of section 'B' of Figure 6. The technical terms used herein are for the reference of specific embodiments only and are not intended to limit the invention. The singular forms used herein include plural forms unless phrases clearly indicate otherwise. The meaning of "comprising" as used in the specification specifies a particular characteristic, area, integer, step, action, element, and/or component, and does not exclude the presence or addition of other particular characteristic, area, integer, step, action, element, component, and/or group. Unless otherwise defined, all terms used herein, including technical and scientific terms, have the same meaning as generally understood by those skilled in the art to which the present invention pertains. Terms defined in commonly used dictionaries are further interpreted to have meanings consistent with relevant technical literature and the present disclosure, and are not interpreted in an ideal or highly formal sense unless otherwise defined. For example, the term "applied" described below is interpreted to include both the state of being appropriately used and the state prior to being appropriately used. Expressions described in the singular in this specification may be interpreted as singular or plural unless explicit expressions such as "one" or "single" are used. In this specification, terms including ordinal numbers, such as first, second, etc., may be used to describe various components, but said components are not limited by said terms. Such terms are used solely for the purpose of distinguishing one component from another. For example, without departing from the scope of the present disclosure, the first component may be named the second component, and similarly, the second component may be named the first component. In the flowchart described with reference to the drawings in this specification, the order of operations may be changed, several operations may be merged or some operations may be divided, and certain operations may not be performed. Embodiments of the present invention are described below with reference to the attached drawings so that those skilled in the art can easily implement the invention. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein. FIG. 1 is a perspective view of a safety device (100) [hereinafter referred to as 'safety device (100)'] for preventing arc contact between wires when installing a power meter according to a first embodiment of the present invention, and FIG. 2 is a magnified view of part 'A' of FIG. 1.
