Description

Switch-shaped switch and its assembly method {Switch half-buried in the ground and Method for assembling the same}

The present invention relates to a ring-shaped switch, and more particularly, to a ring-shaped switch capable of reducing the size and securing the viewing rights by increasing the underground ratio and a method of assembling the same.

In general, the power supplied to the consumer side in the substation is usually boosted to about 22,000 ~ 26,000Ｖ, and in large cities, power cables are buried underground in consideration of the beauty of the city.

Accordingly, the electric power company is installing a ground switchgear that can control the power supply on the ground of the roadside or sidewalk for the protection of the power system, the ground switch is provided in the enclosure type, the switch body and the switchgear having a front door It consists of electrical controls provided inside the body.

Since the ground switch is installed on the ground of the roadside or sidewalk, the base of the switch body is fixed to the top of the foundation after installing the foundation on the excavated ground, so that the height of the body of the actuator protruding from the ground is increased from the ground. As installed so as to protrude up to 1300mm ~ 1400mm there is a problem of violating the right of view and view of the surrounding shopping mall.

In addition, there is a problem that the ground switchgear is installed on the ground of the densely populated area to hinder the pedestrian's passage and harm the aesthetics of the city.

Moreover, since the door body is provided only on the front side of the switch body of the conventional ground switchgear, in order to operate the control device provided in the inside of the switch body, it is necessary to open and operate the door provided on the front side. Of course, the work efficiency is greatly reduced.

In addition, the conventional ground switch, the ground to increase the height of the ground switch by the protruding foundation as the base to protrude from the ground to prevent the inundation, and additional work that must be finished in the bottom of the foundation and the ground switch body with silicon There is a problem that the work time and installation workability due to the installation is greatly reduced due to the process.

In order to solve this problem, Korean Patent Registration No. 10-1784654 (Registration Date: September 27, 2017) has been proposed. Korean Patent No. 10-1784654 lowers the height of the switchgear installed in the base as the lower part of the control body is inserted into the inside of the base, and the top of the switch is opened or closed by hinged the door panel to the frame. It is made of a cover body, characterized in that the upper door is formed in the housing.

However, in this case, there is still a problem that the height of the ground switchgear (about 1.3 m from the ground) protrudes to a considerable extent, which hinders the customer's view and passage right.

In addition, since the size of the ground switch is large, the center of gravity is concentrated on one side, which causes inconvenience in moving and / or installing. In addition, there is a problem in that the terminal device, the controller, the battery, etc. are located outside to be vulnerable to leakage, condensation, etc. In addition, since the handle protrudes from the upper door side of the housing there is a problem that can cause physical damage to the public.

1. Korean Registered Patent No. 10-1784654 (Registration Date: 2017.09.27) 2. Korean Patent No. 10-1275193 (Registration Date: 2013.06.10) 3. Korean Patent Publication No. 10-2008-0043958

Referring to FIG. 4, a portion of the front base plate 120 and the front sub plate 130 where the base 10 and the seating frame 341 are assembled is enlarged. At this time, one end of the front base plate 120, the base coupling portion 451 is coupled to the base 10 is formed.

Accordingly, the work space may be formed or blocked by the front base plate 120 and the front sub plate 130 between the base 10 and the support assembly 350 of FIG. 3. The reason for this is that the housing (110 in FIG. 2) is not completely detached from the support assembly 350 when working on the lower side of the mechanism assembly 340 which is located on the lower side of the base 10. This is to make it possible to workbox without.

The watertight rubber packing 301-1 is disposed between the periphery of the lower surface of the support assembly 350, the base 10, and the front base plate 120. As shown in FIG. 4, as the watertight rubber packing 301-1 is provided between the support assembly 350 and the front base plate 120 and the base 10, the base 10 is provided.

Even if the top of the) is installed on the ground and the horizontal line, it prevents rainwater or sewage from entering the interior of the foundation 10, and also protrudes the top of the foundation from the ground for watertightness during the existing ground switch installation work. It is possible to prevent the watertightness from being deteriorated due to the hassle of waterproofing the silicon by working along the upper periphery of the protruding base and the damage or deterioration of the worked silicon.

FIG. 5 is a perspective view of the upper portion of the ring-shaped switch 100 shown in FIG. 1. Referring to FIG. 5, a control box 330 includes a terminal 533 for user manipulation, a controller 532 performing control according to the control of the terminal 533, and the terminal and the controller for waterproofing. A battery 531 for supplying power and an optical modem 535 for communicating with the outside may be installed. In addition, a dehumidifier 534 may be configured to dehumidify the inside of the control box 330 to prevent malfunction due to condensation.

In addition, a voltage transformer (PT) 510 is installed on the upper right side of the support assembly 330. An assembly hole 351-1 for assembling and fastening with the housing 110 and / or the base 10 is formed in the support assembly 330.
