Description

[Technical field]

[0001] The present invention relates to a construction switch control system equipped with a construction switch used in construction work on a power distribution system. [Background technology]

[0002] Pole-mounted switches are permanently installed on utility poles in power distribution systems for the purpose of dividing the power distribution lines during work or isolating them in the event of a fault (see, for example, Patent Document 1). Patent Document 1 describes a switch attached to a utility pole and a bell-shaped slave station case.

[0003] The control unit is housed in the upper part of the inside of the slave station case, and the operation device is housed in the lower part. The control unit is electrically connected to the switch via a cable. An operation unit is provided on the bottom of the operation device. The operation unit has a handle for operating the switch and a display unit such as an LED.

[0004] In such a configuration, if a distribution line fault occurs and the switch in the faulty section is switched off, an operator climbs the utility pole and operates the operating part of the operating device, and in response to the operation, a control command is issued from the control part to the switch, so that the switch that was in the open state can be switched to the closed state.

[0005] However, because the operation unit is provided on the bottom of the control device, the worker must look into the bottom of the device to operate it, which makes it difficult to operate the handle and check the display unit. In addition, the worker must perform these operations while climbing the utility pole, which forces him into an awkward position and makes workability very poor.

[0006] [Patent Document 1] Japanese Patent Application Publication No. 10-69842 Summary of the Invention [Problem to be solved by the invention]

[0007] During construction work on a power distribution system, such as re-wiring of distribution lines, construction switches are temporarily installed on utility poles to prevent power outages for customers in the re-wiring section. A phase detector is connected to the construction switch, and the voltage and phase detection status is confirmed from the LED status of the phase detector. Furthermore, the construction switch releases the interlock by operating the toggle switch of the phase detector. The interlock release operation is an operation to prevent accidents caused by incorrect connection to the construction switch or incorrect closing when not connected.

[0008] The LED display and switches are located on the underside of the construction switchgear (see Figure 2(b)). However, when attempting to observe them from the ground, they are small and far away, and are difficult to see due to backlighting or because other pole-mounted equipment gets in the way. For this reason, in the past, a work supervisor stood by on the ground while workers climbed onto the pole to check the LEDs and operate the switches from close range. Furthermore, depending on the installation position of the construction switchgear, the LED display cannot be seen by workers on the pole, forcing the worker into an awkward position when releasing the interlock on the pole.

[0009] In view of the above problems, the present invention aims to provide a construction switch control system that can improve the safety and workability of construction work on a distribution system using construction switches. [Means for solving the problem]

[0010] In order to solve the above problems, a typical configuration of the construction switch control system of the present invention comprises a construction switch installed overhead on a utility pole of a power distribution system, a phase detector connected to the construction switch, a short-range wireless communication device built into the phase detector, and a mobile terminal that performs short-range wireless communication with the phase detector, wherein the phase detector acquires equipment status information including voltage detection / phase detection status or on / off status or interlock status from the construction switch, the short-range wireless communication device has individual identification data, and when connected by the mobile terminal specifying the identification data, it transmits the equipment status information acquired by the phase detector to the mobile terminal, and the mobile terminal displays the equipment status information on a screen.

[0011] In the above configuration, the phase detector connected to the construction switch acquires the equipment status information of the construction switch. The short-range wireless communication device built into the phase detector has individual identification data, and when the identification data is specified by the mobile terminal and a connection is made, the short-range wireless communication device transmits the equipment status information to the mobile terminal. The mobile terminal then displays the equipment status information on its screen, allowing the phase detector to be remotely operated by operating the screen.

[0012] This allows workers to check the equipment status information of the construction switch on the screen of a mobile terminal and remotely operate the phase detector with a mobile terminal during construction work on a power distribution system. Therefore, workers do not need to climb utility poles to check the equipment status of the construction switch or to operate the construction switch. Therefore, the above configuration can improve the safety and workability of construction work on a power distribution system using construction switches.

[0013] The above-mentioned phase detector preferably has an interlock function and can release the interlock by operating a mobile terminal. This allows workers to release the interlock remotely, thereby further improving the safety and workability of construction work.

[0014] The mobile terminal may display the device status information on a screen and output the device status information by voice, allowing the worker to check the device status information not only visually but also aurally, thereby minimizing human error. Effect of the Invention

[0015] According to the present invention, it is possible to provide a construction switch control system that can improve the safety and ease of construction work on a power distribution system using construction switches. [Brief description of the drawings]

[0017] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. The dimensions, materials, and other specific values ​​shown in the embodiment are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In this specification and drawings, elements having substantially the same functions and configurations are given the same reference numerals to avoid repeated explanations, and elements not directly related to the present invention are not shown.

[0018] 1 is a functional block diagram of a construction switch control system 100 according to an embodiment of the present invention. The construction switch control system 100 includes a construction switch 102 used in construction work on a power distribution system, a phase detector 104, a short-range wireless communication device 106 built into the phase detector 104, and a mobile terminal 108.

[0019] The construction switch 102 is temporarily installed on a utility pole 109 (see FIG. 2(b)) to prevent power outage for customers in the re-wired section during construction work on a power distribution system, such as re-wired work on a distribution line. The phase detector 104 is connected to the construction switch 102, and has an equipment status information acquisition unit 110 and an LED display unit 112. The phase detector 104 also has an interlock function and can release the interlock of the construction switch 102.

[0020] The equipment status information acquisition unit 110 acquires equipment status information from the construction switch 102. The equipment status information is information including the voltage detection / phase detection state, the on / off state, or the interlock state of the construction switch 102. The LED display unit 112 is disposed on the bottom surface 113 (see FIG. 3) of the phase detector 104, and displays a predetermined equipment status.

[0021] The short-range wireless communication device 106 is a device that performs short-range wireless communication with the mobile terminal 108 by Bluetooth (registered trademark), and has individual identification data (here, a Bluetooth ID). Note that the individual identification data is used as identification data for the phase detector 104, since the short-range wireless communication device 106 is built into the phase detector 104. Note that, as a short-range wireless technology, Wi-Fi (IEEE802.11) or any specified low power can be adopted in addition to Bluetooth, although changes to both the hardware and software are required.

[0022] The mobile terminal 108 is, for example, a mobile terminal, and has a short-range wireless communication device 114 that performs short-range wireless communication with the phase detector 104, and a software screen 116. The mobile terminal 108 performs short-range wireless communication with the short-range wireless communication device 106 built into the phase detector 104 by specifying the above-mentioned identification data using the built-in short-range wireless communication device 114.

[0023] Furthermore, when the short-range wireless communication device 106 is connected by specifying identification data from the short-range wireless communication device 114 of the mobile terminal 108, the short-range wireless communication device 106 transmits the device status information acquired by the device status information acquisition unit 110 of the phase detector 104 to the mobile terminal 108. Then, the mobile terminal 108 displays the device status information on the software screen 116.

[0024] Fig. 2 is a diagram showing the main parts of the construction switch control system 100 of Fig. 1. Fig. 2(a) is a perspective view showing a construction switch 102 and a phase detector 104 attached to the construction switch 102. Fig. 2(b) is a perspective view showing the construction switch 102 and the phase detector 104 of Fig. 2(a) installed overhead on a utility pole 109 of a power distribution system. Fig. 3 is a diagram showing a part of the construction switch 102 and the phase detector 104 of Fig. 2 as viewed from below.

[0025] The construction switch 102 has a casing 118 shown in Fig. 2(a) . Three bushings 122a and 122b are attached to each of two side surfaces 120a and a side surface 120b shown in Fig. 3 of the casing 118.

[0026] A handle 126 for manually opening and closing the circuit of the construction switch 102, and an indicator 128 are attached to the front surface 124 of the casing 118. The indicator 128 shows whether the circuit of the construction switch 102 is in the ON or OFF state.

[0027] A U-shaped hanger 132 as shown in Fig. 2(a) is attached to the upper part of the front face 124 and rear face 130 (see Fig. 3) of the casing 118. A bracket 134 is attached to the hanger 132, and a shaft 136 is held by the bracket 134. By attaching a lifting hook 138 to this shaft 136, the lifting hook 138 is positioned above the construction switch 102. By pulling up the lifting hook 138 in this state, the construction switch 102 can be lifted.

[0028] 3, the phase detector 104 is attached to the bottom surface 140 of the casing 118. As described above, the LED display unit 112 is disposed on the bottom surface 113 of the phase detector 104. The LED display unit 112 displays, for example, each of the following states: power, communicating, interlock release, out of phase, on / off, and trip.

[0029] The construction switch 102 also has a frame 142 as shown in Fig. 2(a). The frame 142 is attached to the casing 118, and is provided with wheels 144 and a support portion 146. By having such a frame 142 attached, the construction switch 102 can be easily transported to the site when construction work is performed on the power distribution system.

[0030] The construction switch 102 is installed overhead in the middle of a distribution line 148 supported by a utility pole 109 as shown in FIG. 2(b), and is further connected to the distribution line 148 via switch lead wires 150a, 150b which are connected to bushings 122a, 122b.

[0031] Fig. 4 is a flowchart showing the operation of the construction switch control system 100 of Fig. 1. During construction work on a power distribution system, the construction switch control system 100 searches for the construction switch 102 by the short-range wireless communication device 114 of the mobile terminal 108 (step S100).

[0032] Next, if the construction switch 102 is present (step S102, Yes), the mobile terminal 108 displays the identification data (Bluetooth ID) of the short-range wireless communication device 106 built into the phase detector 104 on the software screen 116, and when the identification data is specified by the worker's screen operation, communication with the phase detector 104 is established (step S104). Note that if the construction switch 102 is not present in step S102 (No), the mobile terminal 108 searches for the construction switch 102 again.

[0033] The phase detector 104 also acquires the equipment status information of the construction switch 102 by the equipment status information acquisition unit 110. When the identification data is specified and a connection is made from the mobile terminal 108 in step S104, the short-range wireless communication device 106 built in the phase detector 104 transmits the equipment status information acquired by the phase detector 104 to the mobile terminal 108 (step S106).

[0034] Next, the mobile terminal 108 displays the equipment status information of the construction switch 102 transmitted from the short-range wireless communication device 106 on the software screen 116 (step S108), and the worker remotely operates the phase detector 104 by operating the screen (step S110). In addition, in step S108, the mobile terminal 108 may not only display the equipment status information on the software screen 116, but also output the contents of the equipment status information by voice from a speaker.

[0035] Fig. 5 is a diagram showing the screen configuration of software screen 116 in Fig. 1. Figs. 6, 7, and 8 are diagrams showing screen images of each screen configuration of software screen 116 in Fig. 5, respectively.

[0036] As shown in FIG. 5, the software screen 116 includes, as an example, a menu screen 152, a status display screen 154, an interlock release confirmation screen 156, an installation information setting screen 158, a status display panel screen 160, and an installation information list screen 162.

[0037] An example of a selection screen for a connection destination list is displayed on a menu screen 152 shown in Fig. 6(a). An operator can establish communication with the phase detector 104 by operating the menu screen 152. An example of a display screen for the equipment status is displayed on a status display screen 154 shown in Fig. 6(b). An operator can check equipment status information of the construction switch 102 on the status display screen 154.

[0038] An example of an interlock operation screen is displayed on an interlock release confirmation screen 156 shown in Fig. 7(a). An operator can remotely release the interlock by operating the interlock release confirmation screen 156. In addition, an operator can remotely set and initialize the installation information by operating an installation information setting screen 158 shown in Fig. 7(b).

[0039] The status display panel screen 160 shown in Fig. 8(a) displays each status of the construction switch 102, similar to the display of the LED display unit 112 of the phase detector 104 shown in Fig. 3. The worker can check each status of the construction switch 102 on the status display panel screen 160. The worker can also check the installation information on an installation information list screen 162 shown in Fig. 8(b).

[0040] In this way, with the construction switch control system 100, during construction work on the power distribution system, workers can check the equipment status information of the construction switch 102 on the software screen 116 of the mobile terminal 108 and can remotely operate the phase detector 104 using the mobile terminal 108.

[0041] Therefore, workers do not need to climb utility pole 109 to check the equipment status of construction work switch 102 or to operate construction work switch 102. Therefore, construction work switch control system 100 can improve the safety and workability of construction work on a power distribution system using construction work switch 102.

[0042] In addition, workers can release the interlock remotely, which can improve the safety and workability of construction work. Furthermore, the mobile terminal 104 displays the equipment status information on the software screen 116 and outputs the contents by voice, so workers can check the equipment status information not only visually but also audibly, which can minimize human error.

[0043] Furthermore, in the construction switch control system 100, the construction switch 102 can be identified by the mobile terminal 108, which is a mobile terminal, by using individual identification data of the short-range wireless communication device 106 built into the phase detector 104. Also, a name to be displayed on the mobile terminal 108 may be set separately from the identification data of the short-range wireless communication device 106, thereby enabling detailed identification of the construction switch 102 for each construction job. Furthermore, the mobile terminal 108 may have a function to set restrictions so that the identification data of each construction switch 102 is not duplicated.

[0044] Although the preferred embodiment of the present invention has been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such an example. It is clear that a person skilled in the art can think of various modified or altered examples within the scope of the claims, and it is understood that such examples also naturally belong to the technical scope of the present invention.
