Description

Overhead break switch for mounting on steel cross arms}

The present invention relates to a machining switch, and more specifically, to a fully-mounted machining switch for simplification of installation.

An overhead shut-off/switch is a device installed on a utility pole and used to open/close an electric circuit or change the connection status. In general, a sealed metal housing (not shown) is provided that contains a contact/blocking unit and an operating unit that operates the contact/blocking unit.

A lever (not shown) for manually operating the operating unit is installed on one side of the housing (not shown), and a bushing (not shown) is installed on the other side to surround and insulate the terminal to which the wire is connected.

Additionally, SF ₆ gas is injected into the interior of the housing (not shown) to insulate the housing (not shown) and at the same time extinguish the arc that occurs when the contact portion is contacted.

However, when installing such a processing switch, it is located at the bottom of the complete steel, so the pole is complicated, the risk of safety accidents is high when working with live wires, and the work time takes a long time. In addition, there are many connection points between wires and switches (4 locations per phase), so there are many factors causing failures.

Hereinafter, with reference to the attached drawings, a complete iron mounted machining switch according to an embodiment of the present invention will be described in detail.

Figure 1 is a conceptual diagram in which the complete iron mounted processing switch (100a to 100c) according to an embodiment of the present invention is installed on the complete iron (110). Referring to Figure 1, the complete iron 110 is composed of a first sub complete iron 111a and a second sub complete iron 111b, and the first sub complete iron 111a and the second sub complete iron 111b are spaced apart from each other at regular intervals. It is placed in Jeonju (not a city).

The fully-mounted machining switch (100a to 100c) is configured for each phase. To elaborate, if there are three phases, a first overhead switch (100a) for the a-phase, a second overhead switch (100b) for the b-phase, and a third overhead switch (100c) for the c-phase are each configured. Of course, it may be composed of two overhead switches for a single phase, or it may be composed of four overhead switches for three or more phases.

The complete iron mounted processing switch (100a to 100c) is formed integrally with the leg portion 101 and the leg portion 101 inserted between the first sub complete iron (111a) and the second sub complete iron (111b) and the first sub complete iron (111a). It consists of a head part 102 mounted between 111a) and the second sub complete iron (111b). In other words, it becomes a T shape.

A high-voltage power line 140 and a bushing 133 surrounding the outer peripheral surface of the high-voltage power line 140 are connected to both ends of the head 102. The material of the bushing 133 may be a polymer compound, which is an insulating material.

Of course, the exterior material of the head portion 102 and/or the leg portion 101 may generally be an insulating non-ferrous metal or engineering plastic, but a metal material with an insulating inner surface may also be used.

A bolting method may generally be used to secure the complete iron mounted machining switch (100a to 100c) to the complete iron 110. Of course, a method using adhesive is also possible, and a method of fixing it using a wire is also possible. Adhesives include silicone, epoxy, ethylene-vinyl acetate, polyolefin, styrene block copolymer, polyamide, polyester, and urethane adhesives.

In addition, a switch 150 may be configured to turn on and off the fully iron mounted machining switches 100a to 100c. The switch 150 may be composed of a moving member 151 that can simultaneously turn on the first to third processing switches 100a to 100c, and a lever 152 that moves the moving member 151 in the vertical direction.

Figure 2 is a conceptual diagram of the all-steel mounted machining switch (100a to 100c) shown in Figure 1. Referring to FIG. 2, the fully iron mounted machining switch (100a to 100c) has a vacuum interrupter 210 inside, an actuator 240 that opens and closes by operating the vacuum interrupter 210, and a connection part 220 connected to the actuator 240. , may be configured to include a driving unit 230 that operates the actuator 240.

The driving unit 230 is connected to the switch 150 and is turned on and off by the operation of the switch 150. A ring shape is formed at both ends of the lever 152 of the switch 150, and wires 201 and 202 are connected to both ends. Accordingly, the user can turn the switch 150 on and off using the wires 201 and 202. That is, the left wire 201 can be used as off and the right wire 202 as on.

To elaborate, as shown in the dotted box, when the right wire 202 is pulled downward, the gear 251 rotates clockwise and engages the screw thread 253 formed on the moving member 151. Accordingly, as the moving member 151 moves upward, the contact portions 254a, 254b, and 254c that are inclined at the upper end contact the switching terminal 256. Of course, the switching terminal 256 has a structure in which two bars made of conductive material are arranged side by side with a certain gap. That is, when the contact parts 254a, 254b, and 254c contact the switching terminal 256, they are in the on state.

In contrast, when the left wire 201 is pulled downward, the gear 251 rotates counterclockwise and the moving member 151 moves downward. In this case, when the contact portions 254a, 254b, and 254c are separated from the switching terminal 256, they are in an off state.

The movable member 151 has an “∈” shape.

Figure 3 is an internal configuration diagram of the all-steel stationary machining switch (100a, 100b, 100c) shown in Figure 1. Referring to FIG. 3, the fully mounted machining switches 100a, 100b, and 100c are composed of a motor 230 that operates the actuator 240, and a drive circuit 231 that rotates the motor 230 at a certain angle. The driving circuit 231 is turned on and off by the switch 150 and performs the function of supplying power to the motor 230. Power can be supplied by installing a battery, or commercial power can be supplied from an electric pole. In this case, a supply, converter, regulator, etc. may be configured.

The actuator 240 may be composed of a rod 310b that moves in the left and right directions, and a bracket 310a that holds the rod 310b. A connection terminal 351 is installed inside the bushing 133.

FIG. 4 is an enlarged perspective view showing the coupling relationship between the motor 232 and the actuator 240 shown in FIG. 3. Referring to FIG. 4, a second gear 411b is installed at the end of the hinge 461, and a first gear 411a is installed to mesh with the second gear 411b. This first gear 411a is connected to the rotation shaft of the motor 231. This hinge 761 has a protrusion formed to rotate only at a certain angle. Additionally, the rod 310b is connected to this protrusion by a bolting method so that the rod 310b can be rotated.

In addition, a connection terminal 351 is connected to the support frame 461a on the bracket 310a to enable linear reciprocating movement. An elastic member 487 is installed between the support frame 461a and the connecting plate 481, and the connecting plate 481 is fastened and assembled with a hinge connecting plate 483 connected to the upper end of the rod 310b. The linear motion plate 485 is rotatably coupled with respect to its center between the lower and right end sides of the hinge connection plate 483, and the connection terminal 351 is coupled therethrough.

Of course, Figure 4 is simplified to explain the concept of operation and other components are omitted. Since this is widely known, further explanation will be omitted.

Figure 5 is a conceptual diagram in which the fully-mounted machining switch (100a, 100b, 100c) according to an embodiment of the present invention is installed on the electric pole (510). Referring to FIG. 5, as the fully-mounted machining switch (100a, 100b, 100c) is installed on the complete iron, only about two connection points (521, 522) are required for each phase. In the conventional case, as the overhead switch was installed at the bottom of the electric pole, the number of switches per phase was reduced to two compared to four required.

FIG. 6 is a plan view of the electric pole 510 shown in FIG. 5. Referring to Figure 6, a processing switch that can be attached to each phase can be installed on an existing complete iron. Safety accidents can be prevented during work due to line simplification and can also contribute to breakdown prevention.

In addition, there is no need to install suspension insulators and related metal fittings, thereby reducing material and labor costs. Switches, transformers, and high-voltage incoming lines can be installed simultaneously on one electric pole.

In other words, the processing switch can be installed on the iron, and the transformer can be installed underneath it.

In addition, an overhead switch can be installed on a complete iron, and a high-voltage incoming line can be installed underneath it.

Additionally, the processing switch can be installed in two stages. In other words, if complete iron is installed at intervals on the electric pole, it is possible to install a processing switch in two stages.
