Abstract
The present invention relates to a cutout switch (COS) incorporating an arrester installed in the pole of the distribution line, and for this purpose, in the cutout switch having a body (1) and a fuse holder (2), the body (1) A lightning arrester 3 made of a non-linear metal oxide material is wrapped inside the polymer insulating housing 4, and the upper end terminal 3a of the arrester 3 is inserted into a contact bracket of a cutout switch. 5) and the electric wire 6, and the secondary lead lower terminal 3b of the arrester 3 is connected to the ground wire (7).
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cut out switch (COS) incorporating an arrester installed at the pole of a distribution line.
As is well known, the special high voltage cut-out switch (COS) is a device for overcurrent blocking used to protect the transformer and to open and close the line of transformer / high voltage customers by attaching it to the primary side of the main transformer of the distribution line and the high voltage responsible demarcation point. If the fuse is melted, the cover of the switch is open at high pressure and the fuse holder is opened by gravity at high pressure, so it is easy to check the fuse of the fuse from afar.If the enclosed rod is used instead of the fuse, it can be used as a disconnecting device. .
On the other hand, the power arrester is mainly installed in the equipment and special places in the AC current system, and is used to protect the electrical equipment from overvoltage caused by brain or circuit opening and closing.
An arrester for this purpose is installed on the power line of the cutout switch (COS) as much as possible on the distribution line.When installing the arrester for power on the line, install the arrester for each phase on the complete line of the power line. The primary lead wire of is a high-voltage cut-off insulated wire, which is compressed by a branch sleeve to each phase power line, and is connected to the neutral terminal by connecting the ground wire to the secondary terminal of the arrester.
However, according to the related art, since the arrester and the cutout switch are separately installed, the work time and the construction cost increase due to the two work processes during the first connection and the initial new construction of the lead wire.
Accordingly, the present invention has been invented to solve the conventional problems as described above, the lightning arrester inside the cutout switch body and the upper terminal of the arrester is to be connected and energized with the upper contact bracket of the cutout switch It is an object of the present invention to provide a cutout switch incorporating an arrester configured to allow the primary upper terminal of the lightning arrester and the upper connection terminal of the cutout switch to be energized simultaneously with one primary lead of the cutout switch.
In order to achieve the above object, the present invention incorporates a lightning arrester characteristic element inside a body of a cutout switch, and an upper terminal of the arrester is connected to an upper contact bracket of the cutout switch, and a lower terminal of the arrester is connected to a ground line. It is made of structure.
The present invention integrates a cutout switch and an arrester for switching a transformer and a high voltage customer when installing an arrester to prevent brain accidents in a distribution line circumferential line and an extra-high voltage customer responsible demarcation point, and has two functions to increase device efficiency and lower manufacturing costs. In addition, the primary lead wires of the cutout switch and the arrester can be used in common, thereby simplifying the construction and reducing the construction cost.
