Description

  The present invention relates to a switch capable of inserting an automatic voltage regulator into a distribution line or disconnecting from the distribution line.

  At the service entrance for consumers in the power distribution system, the supply voltage must be maintained within the range specified by the Electricity Business Law. Therefore, it is necessary to manage the voltage so that the supply voltage does not deviate from the range to be maintained due to voltage drop or voltage fluctuation. One of the management methods is an automatic voltage regulator (SVR: Step Voltage Regulator, automatic voltage regulator for distribution, and high voltage automatic voltage regulator) that adjusts the voltage in the line and compensates for the voltage at the inlet. Is called).

  FIG. 13 is an explanatory diagram for explaining the operation of the automatic voltage regulator. For example, in an arbitrary parallel line (feeder) in the same distribution system, when the automatic voltage regulator 10 is not disposed, a broken line in FIG. 13 corresponds to the distance from the distribution transformer 12 that is a power supply source. As shown, the voltage drop occurs and the system voltage deviates from the allowable minimum value. Therefore, when a plurality of automatic voltage regulators 10A and 10B are sequentially arranged on parallel lines, the arranged automatic voltage regulators 10A and 10B compensate for the system voltage as shown by the solid line in FIG. Even in the downstream, power supply to the consumer can be continued while maintaining an appropriate voltage range.

  In addition, at the time of maintenance inspection, replacement, and failure of such an automatic voltage regulator, it is necessary to electrically disconnect the automatic voltage regulator from the distribution line while maintaining power supply to the consumer. The automatic voltage regulator is disconnected by providing a switch between the distribution line and the automatic voltage regulator and changing the connection relationship.

  FIG. 14 is a circuit diagram showing a connection relationship between the automatic voltage regulator 10 and the switch 14 (14A, 14B, 14C). Here, the switch 14A opens and closes the power supply side and the load side of the distribution line 16, the switch 14B opens and closes the power supply side terminal of the switch 14A and the primary side terminal of the automatic voltage regulator 10, and the switch 14C. Opens and closes the load side terminal of the switch 14 </ b> A and the secondary side terminal of the automatic voltage regulator 10. The switch 14A and the switches 14B and 14C are exclusively opened and closed, and the switch 14A is opened (opened) as shown in FIG. 14A while supplying power to the automatic voltage regulator 10. The switches 14B and 14C are closed.

  Further, at the time of maintenance inspection or replacement of the automatic voltage regulator 10, as shown in FIG. 14B, the switch 14A is closed, and the switches 14B and 14C are opened to open the distribution line 16 and the automatic voltage regulator 10. And the electrical voltage regulator 10 can be maintained and inspected while maintaining power supply to the consumer.

  FIG. 15 is a layout diagram for explaining the layout of the conventional automatic voltage regulator 10 and switches 14A, 14B, 14C. Conventionally, since the automatic voltage regulator 10 has a large occupied volume and its weight, the automatic voltage regulator 10 is supported by an H column mounting column using two power columns 18A and 18B. Further, not only the automatic voltage regulator 10 but also the three switches 14A, 14B, and 14C require a large installation space as shown in FIG. In recent years, the development of the automatic voltage regulator 10 has progressed, and the automatic voltage regulator 10 for a single column mounting column has also been realized. Accordingly, it is desired to reduce the size and weight of the switch 14 that enables a single column mounting column. Became.

  Thus, a technology has been developed that integrates the functions of the three switches 14A, 14B, and 14C into one device and integrates the connection of the automatic voltage regulator 10 to the distribution line 16 (for example, Patent Document 1). Moreover, the technique which implement | achieves each opening / closing operation | movement timing of the switch integrated in this way with the simple structure using the rotating gear is also disclosed (for example, patent documents 2 and 3).

  FIG. 16 is a layout diagram for explaining the layout of the automatic voltage regulator 10 and the switch 20 when the three switching functions are integrated. In FIG. 16A, the automatic voltage regulator 10 and the single switch 20 are mounted on a single column, and the automatic voltage regulator 10 is connected to the distribution line 16 through the switch 20 in which three switching functions are integrated. Has been. By integrating the switch 20 in this way, the maintenance of the automatic voltage regulator 10 and the switch 20 can be simplified, and when the automatic voltage regulator 10 itself fails, the automatic voltage regulator 10 can be easily removed from the distribution line. Can be separated.

  The switch 20 performs the disconnection of the automatic voltage regulator 10 from the distribution line 16, but does not have the function of separating itself from the distribution line 16. Therefore, when the switch 20 is newly installed or removed, the operator directly cuts the wiring (live line) on the load line 16 load side of the switch 20 as shown in FIG. Although the operation is performed, since the switch 20 is exclusively prepared with two modes of linking or disconnecting the automatic voltage regulator 10, the disconnected wiring is in any mode. It hangs down freely while being energized. Therefore, in order to ensure the safety of workers, the system power supply itself is stopped, or an uninterruptible work (bypass cutout method) is performed by a bypass line.

FIG. 17 is an explanatory diagram for explaining the uninterruptible work by the bypass cutout method. Here, first, the two distribution lines 16 extending from the target switch 20 to the power supply side and the load side are connected by a bypass line 24 via a bypass switch (construction switch) 22. Then, the cutting point 26 of the distribution line 16 is determined, and both sides are stretched with wires 28 to cut the distribution line 16. Thus, the distribution line 16 between the two cutting points 26 can be de-energized, and the switch 20 can be newly installed or removed.
Japanese Patent Laid-Open No. 11-54000 JP 2003-16884 A JP-A-2005-32497

  However, such new installation or removal of the switch 20 itself involves a complicated operation with a plurality of jigs such as a bypass line as described with reference to FIG.

  In view of such problems, the present invention has an object to provide a switch capable of quickly and surely performing new installation or removal of a switch by an easy operation while ensuring the safety of an operator. Yes.

  In order to solve the above-described problems, a typical configuration of a switch according to the present invention includes a closed circuit between a power supply side end of a distribution line and a primary terminal of an automatic voltage regulator, and a secondary side of an automatic voltage regulator. A first opening / closing part that slides and switches between a terminal and a load side end of the distribution line, and a power supply side end and a load side end of the distribution line and a closed line at both ends of the relay line in the switch And a second opening / closing part that opens and closes the relay line itself, and automatically connects at least the regulator interconnection mode in which the automatic voltage regulator is linked to the distribution line, and directly connects the ends of the distribution line. There are three modes: a regulator disconnecting mode for disconnecting the voltage regulator, and a line opening mode for opening between the ends of the distribution line.

  When the switch is newly installed or removed, since the power supply side terminal and the load side terminal of the switch are in conduction, the energized state of the hung cut end remains even after the load side terminal is divided. In the present invention, since the load side terminal can be cut off from the distribution line by the second opening / closing part, the cut end can be made non-energized, and the safety of the operator can be ensured. In addition, since the disconnection between the distribution line and the load side terminal is carried out in the switch, it is not necessary to cut the distribution line, and a simple configuration such as a jumper line without breaking the bypass line. Thus, it is possible to secure a bypass of the distribution line, and it is possible to perform the new installation or removal of the switch quickly and surely by an easy operation.

  Other typical configurations of the switch according to the present invention include a closed circuit between the power supply side end of the distribution line and the primary terminal of the automatic voltage regulator, and a load on the secondary terminal of the automatic voltage regulator and the distribution line. A first switch for slidingly switching between a closed end with the side end, a closed end between the power supply side end and the load end of the distribution line, and both ends of the relay line in the switch, and the inside of the switch And a second opening / closing part that is inserted into the power supply side or the load side of the first opening / closing part and opens / closes the distribution line and the first opening / closing part, and at least an adjustment in which the automatic voltage regulator is linked to the distribution line There are three modes: the unit connection mode, the regulator disconnection mode that connects the ends of the distribution line directly and disconnects the automatic voltage regulator, and the line open mode that opens between the ends of the distribution line. It is characterized by having.

  The switch according to the present invention is substantially the same in other functions except for the arrangement of the second switch and the switch described above. Therefore, as with the switch described above, it is possible to quickly and surely install or remove the switch with easy work while ensuring the safety of the operator.

  Other typical configurations of the switch according to the present invention include a closed circuit between the power supply side end of the distribution line and the primary terminal of the automatic voltage regulator, and a load on the secondary terminal of the automatic voltage regulator and the distribution line. A closed circuit with the side end, a closed circuit between the power supply side end and the load side end of the distribution line and the both ends of the relay line in the switch, and an open of the power supply side end and the load side end of the distribution line A first open / close portion that slides and switches, and at least an regulator interconnection mode in which an automatic voltage regulator is linked to the distribution line, and an automatic voltage regulator by directly connecting the ends of the distribution line. It is characterized by having three modes: a regulator disconnecting mode for disconnecting and a line opening mode for opening between ends of the distribution line.

  In the switch according to the present invention, the first opening / closing section has the function of the second opening / closing section described above. Therefore, the three modes can be switched simply by slidingly switching the first opening / closing portion, and the configuration can be further simplified.

  The first opening / closing part may be configured by a contact where the movable contact comes into contact with the fixed contact by rotational sliding or linear sliding. With this configuration, it is possible to efficiently switch contacts in a limited occupied space, and it is possible to reliably open and close the contacts according to the open / close signal.

  The second opening / closing unit may be configured by a contact where the movable contact comes into contact with the fixed contact by rotational sliding, or a contact where the movable contact which slides linearly in a stretchable manner contacts the fixed contact. With this configuration, as with the first opening / closing section, it is possible to reliably open and close the contacts according to the opening / closing signal.

  As described above, according to the present invention, it is possible to perform the new installation or removal of a switch quickly and reliably by an easy operation while ensuring the safety of the operator.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical 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 the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are not illustrated. To do.

  At the time of maintenance inspection, replacement, or failure of the automatic voltage regulator, the automatic voltage regulator is switched while switching the connection relation of the switch provided between the distribution line and the automatic voltage regulator to maintain power supply to consumers. Can be electrically disconnected from the distribution line. In addition, when the switch itself is newly installed or removed, when power is supplied to the customer by an edge line or the like, the switch is disconnected while disconnecting the inside of the switch to ensure the safety of the operator. Hereinafter, the configuration of such a switch will be described, and the installation or removal work of the switch will be described in detail.

(First embodiment: switch 100)
FIG. 1 is an arrangement diagram showing the arrangement of the switch 100 and the automatic voltage regulator 110. The switch 100 relays the high-voltage distribution line 102 and the automatic voltage regulator 110, and performs the connection of the automatic voltage regulator 110 to the distribution line 102 or the disconnection from the distribution line 102. The switch 100 is connected to an opening / closing operation unit 120 that manually slides a first opening / closing unit described later from the ground, and a control device 122 that receives an opening / closing command of a second opening / closing unit described later. The reason for changing the switching method of the two opening / closing parts in this way is to avoid an erroneous operation, and the reason why the first opening / closing part is set to manual is that even when power is not supplied to the switch 100. This is for switching one opening / closing part.

  The automatic voltage regulator 110 sets the voltage at the load center point of the high-voltage distribution line 102 on the secondary side (load side) to a predetermined value in order to compensate for a voltage drop that cannot be adjusted by the sending voltage of the substation. The voltage is adjusted by switching the tap on the primary side of the adjustment single winding transformer provided in itself so as to maintain the voltage.

  FIG. 2 is a functional block diagram illustrating a schematic configuration of the switch 100. The switch 100 is configured to include a first opening / closing part 130 and a second opening / closing part 132 that can operate independently of each other.

  The first opening / closing part 130 includes a power supply side end of the distribution line 102 and a primary side terminal of the automatic voltage regulator 110, and a secondary side terminal of the automatic voltage regulator 110 and a load side end of the distribution line 102. Or the two contact states for closing the power supply side end and the load side end of the distribution line 102 and both ends of the relay line 140 in the switch 100 are slidably switched. The second opening / closing unit 132 opens and closes the relay line 140 itself. The two opening / closing parts (the first opening / closing part 130 and the second opening / closing part 132) constitute three modes depending on the state of their contacts.

  FIG. 3 is an explanatory diagram for explaining three modes by the first opening / closing part 130 and the second opening / closing part 132. FIG. 3A shows the connection state of the regulator interconnection mode. Here, the first opening / closing unit 130 closes the power supply side end of the distribution line 102 and the primary side terminal of the automatic voltage regulator 110. In addition, the secondary terminal of the automatic voltage regulator 110 and the load side end of the distribution line 102 are closed, and the automatic voltage regulator 110 is linked to the distribution line 102.

  FIG. 3B shows a connection state of the regulator disconnection mode, in which the power supply side end and the load side end of the distribution line 102 and the both ends of the relay line 140 in the switch 100 are closed. In addition, since the second opening / closing part 132 is also closed, the ends of the distribution line 102 are directly connected to each other and the automatic voltage regulator 110 is disconnected. FIG. 3C shows the connection state in the line open mode, where the power supply side end and load side end of the distribution line 102 and both ends of the relay line 140 in the switch 100 are closed. However, since the 2nd opening-and-closing part 132 is open | released, between the edge parts of the distribution line 102 will open | release (open circuit).

  Normally, the switch 100 is fixed in the regulator interconnection mode shown in FIG. 3A, and the regulator disconnecting mode is used when the automatic voltage regulator 110 is disconnected, and the line opening mode is used when the switch 100 is disconnected. Is selected.

  FIG. 4 is an explanatory diagram for explaining the flow of removal work of the switch 100. Here, first, the automatic voltage regulator 110 is disconnected, and the mode is changed from the regulator interconnection mode to the regulator disconnection mode. When the automatic voltage regulator 110 is disconnected and the distribution line paths 102 are directly connected in the switch 100, the distribution line 102 is bypassed by the jumper line 160 while maintaining the energized state of the distribution line 102. In this way, there are two conduction paths of the distribution line 102, that is, a path that passes through the edge line 160 and a path that passes through the relay line 140 of the switch 100.

  Next, the 2nd opening-and-closing part 132 is open | released, and a regulator disengagement mode is further changed into track | line release mode. In this way, the relay line 140 of the switch 100 is disconnected, and the conduction path of the distribution line 102 is only the path via the edge line 160. Here, when the connection line to the load side of the switch 100 is cut as a live line as indicated by an arrow in the figure, the energized state of the cut end drooped by the cutting has remained in the past, but in this embodiment The line (cut end) on the load side of the switch 100 can be de-energized. Therefore, it is possible to ensure the safety of the worker.

  Further, in the present embodiment, since the disconnection between the distribution line 102 and the load side terminal is performed in the switch 100, the work of cutting the distribution line 102 with a bypass line is not required as in the prior art. The bypass of the distribution line 102 can be ensured with a simple configuration such as the edge line 160. Therefore, it is possible to perform the new installation or removal of the switch 100 quickly and reliably by an easy operation.

  Up to this point, the schematic configuration of the switch 100 and the functions of the first opening / closing part 130 and the second opening / closing part 132 have been described. Hereinafter, specific structures of the first opening / closing part 130 and the second opening / closing part 132 will be described. explain.

  FIG. 5 is a structural diagram showing a specific structure of the first opening / closing part 130. The first opening / closing part 130 is configured by a blade contact in which a movable contact 170 having a blade structure shown separately on the left and right in the drawing contacts the fixed contact 172 (172a, 172b, 172c, 172d, 172e, 172f) by rotation sliding. Then, it is connected to the distribution line 102 and the automatic voltage regulator 110 through the bushing 174. In the regulator interconnection mode, the movable contact 170 is connected to the fixed contact 172a from the distribution line 102 and the fixed contact 172b to the automatic voltage regulator 110 and the fixed contact 172c from the automatic voltage regulator 110 to the distribution line 102. The fixed contact 172d is closed, and the automatic voltage regulator 110 is connected to the distribution line 102.

  Further, in the regulator disconnection mode, the movable contact 170 is pivoted upward in the figure in conjunction with the left and right, and the fixed contact 172a from the distribution line 102, the fixed contact 172e to the relay line 140, and the fixed contact from the relay line 140. 172f and the fixed contact 172d to the distribution line 102 are closed, the ends of the distribution line 102 are directly connected to each other, and the automatic voltage regulator 110 is disconnected.

  FIG. 6 is a structural diagram showing another specific structure of the first opening / closing part 130. The first opening / closing part 130 is integrally formed with two movable contacts 170 having a blade structure provided in parallel to the left and right in the figure, and fixed contacts 178 (178a, 178b, 178c, 178d, 178e, 178f) by linear sliding. It consists of blade contacts that come into contact with. 5, in the regulator linkage mode, the movable contact 176 has a fixed contact 178a from the distribution line 102, a fixed contact 178b to the automatic voltage regulator 110, and a fixed contact from the automatic voltage regulator 110. 178 c and the fixed contact 178 d to the distribution line 102 are closed, and the automatic voltage regulator 110 is connected to the distribution line 102.

  Further, in the regulator disconnection mode, the movable contact 176 linearly moves upward in the figure, and the fixed contact 178a from the distribution line 102, the fixed contact 178e to the relay line 140, and the fixed contact 178f from the relay line 140, The fixed contact 178d to the distribution line 102 is closed, the ends of the distribution line 102 are directly connected to each other, and the automatic voltage regulator 110 is disconnected.

  With this configuration, it is possible to efficiently switch contacts in a limited occupied space, and it is possible to reliably open and close the contacts according to the open / close signal.

  FIG. 7 is a structural diagram showing a specific structure of the second opening / closing part 132. The second opening / closing part 132 is configured by a blade contact in which the movable contact 180 having a blade structure comes into contact with the fixed contact 182 by rotational sliding. Such rotational sliding is performed by a cam 188 that is rotated by an electromagnet 184 and an elastic body (spring) 186. In the line open mode, the shaft portion 190 of the electromagnet 184 protrudes in the direction of the arrow, and the cam 188 is rotated clockwise in the figure against the tension of the elastic body 186 to disconnect the movable contact 180 from the fixed contact 182. . In this manner, the connection state between the power supply side end and the load side end of the distribution line 102 in the regulator disconnection mode can be cut, and the end of the distribution line 102 can be opened. In addition, here, the opening of the second opening / closing part 132 is described, but it goes without saying that the second opening / closing part 132 can be closed by the contraction of the shaft part 190 of the electromagnet 184.

  FIG. 8 is a structural diagram showing another specific structure of the second opening / closing part 132. The second opening / closing part 132 is configured by a tulip contact in which a movable contact 192 that slides linearly in a stretchable manner contacts a fixed contact 194. Tulip contacts are used in air multi-circuit switches and gas multi-circuit switches. Such linear sliding is also performed by the cam 188 rotated by the electromagnet 184 and the elastic body 186, as in the rotational sliding of FIG. In the line open mode, the shaft portion 190 of the electromagnet 184 protrudes in the direction of the arrow, and the cam 188 is rotated clockwise in the figure against the tension of the elastic body 186 to disconnect the movable contact 192 from the fixed contact 194. .

  With this configuration, as with the first opening / closing unit 130, it is possible to reliably open and close the contacts according to the opening / closing signal. In particular, the second opening / closing part 132 has a load opening / closing capability and can cut off the conductive state of the relay line 140. In the first place, since the opening / closing of the load is not assumed for the opening / closing of the automatic voltage regulator 110 in the first place, the operation of the second opening / closing unit 132 cannot be performed.

  FIG. 9 is an explanatory view showing an example in which the first opening / closing part 130 and the second opening / closing part 132 are actually arranged. In the present embodiment, since the second opening / closing part 132 is disposed on the relay line 140, it is located between the fixed contacts on the power supply side and the load side of the first opening / closing part 130 as shown in FIG. The occupied space in the switch 100 can be used effectively, and the switch 100 can be downsized.

(Other switch 200)
In the switch 100 described above, the second switch 132 opens and closes the relay line 140 between the first switches 130, but the second switch is inserted on the power supply side or load side of the first switch. Can do.

  FIG. 10 is a functional block diagram illustrating a schematic configuration of the switch 200. The switch 200 includes a first switch 230 and a second switch 232 that can operate independently from each other, like the switch 100 described above.

  The first opening / closing part 230 includes a power supply side end of the distribution line 102 and a primary side terminal of the automatic voltage regulator 110, and a secondary side terminal of the automatic voltage regulator 110 and a load side end of the distribution line 102. Or the two contact states for closing the power supply side end and the load side end of the distribution line 102 and both ends of the relay line 140 in the switch 100 are slidably switched. The second opening / closing part 232 is inserted in the switch 200 and on the power supply side or load side of the first opening / closing part 230, and opens and closes the distribution line 102 and the first opening / closing part 230. The two opening / closing sections (the first opening / closing section 230 and the second opening / closing section 232) configure the three modes described above, that is, the regulator linkage mode, the regulator disconnection mode, and the line opening mode, depending on the contact state. . The first opening / closing part 130 and the second opening / closing part 132 already described as components in the switch 100 have substantially the same functions as the first opening / closing part 230 and the second opening / closing part 232 of the switch 200 and are open / closed. Since the functions of the respective modes in the device 100 are the same, the duplicated explanation is omitted.

  Also in the switch 200, as with the switch 100 described above, it is possible to quickly and surely install or remove the switch by an easy operation while ensuring the safety of the operator.

  Moreover, the opening / closing part demonstrated using FIG. 5 and FIG. 6 can be employ | adopted as a 1st opening / closing part of each switch 100 and the switch 200, and it demonstrates using FIG. 7 and FIG. 8 as a 2nd opening / closing part. Therefore, it is possible to configure a switch with eight combinations of 2 × 2 × 2 here.

(Second Embodiment: Switch 300)
In the first embodiment, the switch 100 or the switch 200 has the first opening / closing part and the second opening / closing part, respectively. However, the present invention is not limited to this, and an equivalent function is configured only by the first opening / closing part. It is also possible to do.

  FIG. 11 is a functional block diagram illustrating a schematic configuration of the switch 300. The switch 300 is configured by a first opening / closing part 330. The first switch 330 includes a closed circuit between the power supply side end of the distribution line 102 and the primary side terminal of the automatic voltage regulator 110, and a secondary side terminal of the automatic voltage regulator 110 and the load side end of the distribution line 102. Switching between the closed circuit, the closed circuit between the power supply side end and the load side end of the distribution line 102 and both ends of the relay line 140, and the opening of the power supply side end and the load side end of the distribution line 102. To do.

  In the switch 300 according to this embodiment, the first switch 330 has the function of the second switch of the switches 100 and 200 described above. Therefore, it is possible to switch the three modes of the regulator connection mode, the regulator disconnection mode, and the line opening mode just by slidingly switching the first opening / closing portion 330, and to further simplify the configuration. Is possible.

  FIG. 12 is an explanatory diagram for explaining the three modes by the first opening / closing unit 330. FIG. 12A shows the connection state of the regulator interconnection mode. The first opening / closing part 330 closes the power supply side end of the distribution line 102 and the primary side terminal of the automatic voltage regulator 110. In addition, the secondary terminal of the automatic voltage regulator 110 and the load side end of the distribution line 102 are closed, and the automatic voltage regulator 110 is connected to the distribution line 102.

  FIG. 12B shows the connection state of the regulator disconnection mode, where the power supply side end and the load side end of the distribution line 102 and both ends of the relay line 140 in the switch 100 are closed. The automatic voltage regulator 110 is disconnected by directly connecting the ends of the distribution line 102. FIG. 12C shows a connection state in the line open mode, and the relay line 140 is not brought into contact with any contact points, so that the ends of the distribution line 102 are opened.

  Here, as the first opening / closing portion of the switch 300, the opening / closing portion described with reference to FIGS. 5 and 6 can be employed, so that two types of switches can be configured.
