[Modes for carrying out the invention]

[0030] Hereinafter, a detection device, detection unit, power outage detection system, detection program, and detection method for a circuit breaker according to one embodiment of the present invention will be described with reference to the attached drawings.

[0031] In this embodiment, the power outage detection system will also be described, including the detection device, detection unit, detection program, and detection method.

[0032] Before explaining the power outage detection system, let's first explain the circuit breaker.

[0033] As shown in Figure 1, the circuit breaker 5 comprises a circuit breaker body 50 and a switch means 51 provided on the circuit breaker body 50.

[0034] The circuit breaker body 50 includes a primary input terminal block 500 into which power is input, a secondary output terminal block 501 into which power is output, a main circuit (not shown) connecting the input terminal block 500 and the output terminal block 501, and an external terminal block 502 for electrically connecting the switching means 51 to external equipment.

[0035] The input terminal block 500 has three input terminals 5000. These three input terminals 5000 are, in order from left to right in a front view, L1 phase, N phase, and L2 phase.

[0036] The output terminal block 501 has three output terminals 5010. These three output terminals 5010 are, in order from left to right in a front view, L1 phase, N phase, and L2 phase.

[0037] The main circuit is the circuit that is electrically connected to the input terminal block 500 and the output terminal block 501.

[0038] The external terminal block section 502 includes a forced-side external terminal block section 5020 for electrically connecting the forced-side switch means 510 (described later) of the switch means 51 to an external device, and a disconnection-side external terminal block section 5021 for electrically connecting the disconnection-side switch means 511 (described later) of the switch means 51 to an external device.

[0039] The forced external terminal block 5020 has three output terminals 5020a, 5020b, and 5020c, which are aligned from top to bottom when viewed from the front.

[0040] The three output terminals 5020a, 5020b, and 5020c of the forced external terminal block 5020 are terminals for electrically connecting the detection means 2 (forced detection means 20, which will be described later). Furthermore, the detection means 2 is electrically connected to either the uppermost output terminal 5020a and the lowermost output terminal 5020c, or the central output terminal 5020b and the lowermost output terminal 5020c, among the three output terminals 5020a, 5020b, and 5020c of the forced external terminal block 5020.

[0041] The external terminal block 5021 on the disconnect side also has three output terminals 5021a, 5021b, and 5021c, and these three output terminals 5021a, 5021b, and 5021c are also arranged in a line from top to bottom when viewed from the front.

[0042] The three output terminals 5021a, 5021b, and 5021c of the external terminal block 5021 on the interruption side are terminals for electrically connecting the detection means 2 (the interruption side detection means 21, which will be described later). In addition, the detection means 2 is electrically connected to the uppermost output terminal 5021a and the lowermost output terminal 5021c, or to the central output terminal 5021b and the lowermost output terminal 5021c, among the three output terminals 5021a, 5021b, and 5021c, of the external terminal block 5021 on the interruption side.

[0043] The switching means 51 is configured to switch between a conductive state and a non-conductive state in conjunction with switching to at least two states (all states in this embodiment) from among a closed state in which the main circuit is closed, a forced open state in which the main circuit is opened by external power, and a tripped open state in which the main circuit is opened using power (power flowing through the main circuit) as the power source.

[0044] The "forced open state" refers to a state in which the main circuit is opened manually, for example, by operating the handle provided on breaker 5, or by remote operation. The "tripped open state" refers to a state in which the main circuit is opened due to the tripping mechanism provided on breaker 5 activating, i.e., a trip occurring, caused by an abnormal current flowing through the main circuit. Remote operation refers to the operation of opening the main circuit by driving the handle without causing a trip.

[0045] The switching means 51 of this embodiment includes a forced-side switching means 510 whose on / off state is switched as part of the operation of the breaker 5 when the main circuit switches to a closed state, a forced-open state, or a tripped-open state, and a tripped-side switching means 511 whose on / off state is switched as part of the operation of the breaker 5 when the main circuit switches to a closed state or a tripped-open state.

[0046] Furthermore, when the forced-side switch means 510 and the interrupted-side switch means 511 are switched to the ON state, they become conductive, allowing power to pass through, and when switched to the OFF state, they become non-conductive, preventing power from passing through.

[0047] In this embodiment, regardless of the on / off state of the forced-side switch means 510, the state in which power is flowing is referred to as the energized state, and the state in which power is not flowing is referred to as the de-energized state. Similarly, regardless of the on / off state of the interruption-side switch means 511, the state in which power is flowing is referred to as the energized state, and the state in which power is not flowing is referred to as the de-energized state.

[0048] Even if both the forced-side switch means 510 and the interrupted-side switch means 511 are switched to the ON state, if the power supply is interrupted, they will switch from the energized state to the de-energized state.

[0049] Although not shown in Figure 1, the circuit breaker body 50 of this embodiment includes, in addition to the input terminal block 500, output terminal block 501, main circuit, and external terminal block 502 described above, a forced-side operating mechanism for switching the forced-side switch to an open / closed state, and a tripping-side operating mechanism for switching the tripping-side switch to an open / closed state.

[0050] The forced-side switch means 510 is configured to switch to the ON state according to the state of the main circuit that you want to detect via the forced-side switch means 510, which is either the closed state, the forced-open state, or the interrupted-open state of the main circuit.

[0051] In this embodiment, the forced-side switching means 510 is composed of a double-throw switch and is electrically connected to the uppermost output terminal 5020a and the lowermost output terminal 5020c of the three output terminals 5020a, 5020b, and 5020c of the forced-side external terminal block 5020.

[0052] When the forced-side switch means 510 is switched to the ON state, the terminals between output terminal 5020a and output terminal 5020c of the forced-side external terminal block 5020 become conductive, and when the forced-side switch means 510 is switched to the OFF state, the terminals between output terminal 5020c and output terminal 5020a of the forced-side external terminal block 5020 become non-conductive. Therefore, when the forced-side switch means 510 is switched to the ON state, it can output power to the outside via the forced-side external terminal block 5020, but when it is switched to the OFF state, it cannot output power to the outside via the forced-side external terminal block 5020.

[0053] The forced-side switch means 510 in this embodiment is a so-called AX switch, and is configured to switch to the ON state when the main circuit switches to the closed state, and to switch to the OFF state when the main circuit switches to the forced-open state or the interrupted-open state.

[0054] Furthermore, the forced-side switching means 510 is configured as a normally closed (b) contact.

[0055] Therefore, the mandatory switch means 510 is in the ON state when not receiving external input, and is configured to switch from the ON state to the OFF state when it receives external input. The mandatory switch means 510 is configured to return from the OFF state to the ON state when the external input is released.

[0056] The forced-side switch means 510 of this embodiment is configured to be in the ON state when the main circuit is switched to the closed state, and to switch from the ON state to the OFF state when the main circuit changes to a forced-open state or a tripped-open state.

[0057] More specifically, the forced-side switching means 510 includes a forced-side internal circuit 5100 (see Figure 3), a forced-side switching unit 5101 that opens and closes the forced-side internal circuit 5100, and a forced-side switching mechanism 5102 that switches the open / closed state of the forced-side switching unit 5101. The on / off state of the forced-side switching means 510 refers to the open / closed state of the forced-side switching unit 5101.

[0058] The forced-side opening / closing section 5101 is configured to switch between open and closed states by being operated from the outside via the forced-side switching mechanism 5102.

[0059] The forced-side switching mechanism 5102 is configured to operate when operated by the forced-side operating mechanism.

[0060] The forced-side operating mechanism is configured to switch the forced-side switching unit 5101 to the open state via the forced-side switching mechanism 5102 when the main circuit switches to a forced-open state or a tripped-off state, and to switch the forced-side switching unit 5101 to the closed state via the forced-side switching mechanism 5102 when the main circuit switches to a closed state. The forced-side operating mechanism of this embodiment is configured to perform the following actions: The system is configured such that when switching the forced-side opening / closing section 5101 to the open state, the forced-side switching mechanism 5102 is operated, and when switching the forced-side opening / closing section 5101 to the closed state, the operation on the forced-side switching mechanism 5102 is released.

[0061] The forced-side switching mechanism 5102 may be composed of, for example, a microswitch. In this case, the forced-side switching mechanism 5102 should be configured to switch the forced-side switching unit 5101 to the closed state in conjunction with the movement of the handle when the main circuit is switched to the forced-open state, and when the main circuit is switched to the interrupted-open state, and to switch the forced-side switching unit 5101 to the open state in conjunction with the movement of the handle when the main circuit is switched to the closed state.

[0062] The interruption-side switch means 511 is also configured to switch to the ON state according to the state of the main circuit that you want to detect via the forced-side switch means 510, among the closed state, forced-open state, and interrupted-open state of the main circuit.

[0063] In this embodiment, the interruption-side switch means 511 is also composed of a double-throw switch and is electrically connected to the lowermost output terminal 5021c and the uppermost output terminal 5021a of the three output terminals 5021a, 5021b, and 5021c of the interruption-side external terminal block 5021.

[0064] When the interruption-side switch means 511 is switched to the ON state, the terminals between output terminal 5021c and output terminal 5021a of the interruption-side external terminal block 5021 become conductive, and when the interruption-side switch means 511 is switched to the OFF state, the terminals between output terminal 5021c and output terminal 5021a of the interruption-side external terminal block 5021 become non-conductive. Therefore, when the interruption-side switch means 511 is switched to the ON state, it can output power to the outside via the interruption-side external terminal block 5021, but when it is switched to the OFF state, it cannot output power to the outside via the interruption-side external terminal block 5021.

[0065] The interruption-side switch means 511 in this embodiment is a so-called AL switch, and is configured to be in the ON state when the main circuit is switched to the interrupted state, and in the OFF state when the main circuit is switched to the closed state. The interruption-side switch means 511 is also configured to be in the OFF state when the main circuit is switched to the forcibly open state.

[0066] Furthermore, the interruption-side switch means 511 is configured as an normally open (a) contact.

[0067] Therefore, the circuit breaker switch 511 is configured to be in the off state when not receiving external operation, and to switch from the off state to the on state when it receives external operation. The circuit breaker switch 511 is configured to return from the on state to the off state when the external operation is released.

[0068] The interruption-side switch means 511 in this embodiment is configured to be in the off state when the main circuit is switched to the closed state, and to switch from the off state to the on state when the main circuit is switched to the interrupted open state.

[0069] More specifically, the circuit breaker switch means 511 includes a circuit breaker internal circuit 5110 (see Figure 3), a circuit breaker switch 5111 that opens and closes the circuit breaker internal circuit 5110, and a circuit breaker switching mechanism 5112 that switches the open / closed state of the circuit breaker switch 5111. The on / off state of the circuit breaker switch means 511 refers to the open / closed state of the circuit breaker switch 5111.

[0070] The shut-off side opening / closing section 5111 is configured to switch between open and closed states by being operated from the outside via the shut-off side switching mechanism 5112.

[0071] The circuit breaker switching mechanism 5112 is configured to be operated by the circuit breaker operating mechanism.

[0072] The circuit breaker operating mechanism is configured to switch the circuit breaker opening / closing section 5111 to the closed state via the circuit breaker switching mechanism 5112 when the main circuit switches to the circuit breaker open state, and to switch the circuit breaker opening / closing section 5111 to the open state via the circuit breaker switching mechanism 5112 when the main circuit switches to the closed state. In this embodiment, the circuit breaker operating mechanism is configured to operate the circuit breaker switching mechanism 5112 when switching the circuit breaker opening / closing section 5111 to the open state, and to release the operation on the circuit breaker switching mechanism 5112 when switching the circuit breaker opening / closing section 5111 to the closed state.

[0073] The circuit breaker switching mechanism 5112 may also be composed of, for example, a microswitch. In this case, the circuit breaker switching mechanism 5112 should be configured to operate in conjunction with the movement of the handle when switching the main circuit to the open state and in conjunction with the movement of the handle when switching the main circuit to the closed state.

[0074] As shown in Figure 2, the power outage detection system 1 includes a detection means 2 connected to the circuit breaker 5, which has a power supply detection means 20 for detecting the energized state of the switch means 51; a transmission means 3 for transmitting the detection result of the power supply detection means 20 for the powered state of the switch means 51; and a determination means 4 for executing a process to determine the power outage state of the circuit breaker 5 based on the detection result of the power supply detection means 20 for the powered state of the switch means 51.

[0075] In this embodiment of the power outage detection system 1, the detection means 2, the transmission means 3, and the discrimination means 4 are each configured as separate devices. That is, the power outage detection system 1 of this embodiment includes a detection device as the detection means 2, a transmission device as the transmission means 3, and a discrimination device as the discrimination means 4.

[0076] The energization detection means 20 of the detection means 2 consists of an energization-side detection means 200 that detects that the energization-side switch means 510 is in an energized state and notifies the transmission means 3 (hereinafter referred to as the notification operation), and a disconnection-side detection means 201 that detects that the disconnection-side switch means 511 is in an energized state and notifies the transmission means 3 (hereinafter referred to as the notification operation).

[0077] The forced-side detection means 200 is configured to notify in the notification operation that the forced-side switching unit 5101 of the forced-side switch means 510 is in a de-energized state. In this embodiment, the forced-side detection means 200 is configured to notify that the forced-side switching unit 5101 is in a de-energized state by changing its electrical state.

[0078] More specifically, the forced-side detection means 200 includes a forced-side connection circuit 2000 (see Figure 3) connected to the transmitting means 3, a forced-side detection switch 2001 electrically connected to the transmitting means 3 via the forced-side connection circuit 2000, and a forced-side detection operation unit 2002 that switches the open / closed state of the forced-side detection switch 2001 according to the energized state of the forced-side switch means 510.

[0079] In the forced-side detection means 200 of this embodiment, the notification operation is the operation in which the forced-side detection opening / closing unit 2001 switches to the closed state.

[0080] Furthermore, the forced-side detection switch 2001 is configured as a normally closed (b) contact. Therefore, the forced-side detection switch 2001 is in the "on" state when not receiving external input, and switches from the "on" state to the "off" state when external input is received. The forced-side detection switch 2001 is configured to return from the "off" state to the "on" state when the external input is released.

[0081] The forced-side detection switching unit 2001 in this embodiment is configured to be in the ON state when the forced-side switch means 510 is switched to a non-energized state, and to switch from the ON state to the OFF state when the forced-side switch means 510 is switched to an energized state.

[0082] Accordingly, the forced-side detection operation unit 2002 is configured to switch the forced-side detection opening / closing unit 2001 to the open state when the forced-side switch means 510 switches from a non-energized state to an energized state, and to switch the forced-side detection opening / closing unit 2001 to the closed state when the forced-side switch means 510 switches from an energized state to a non-energized state.

[0083] The forced-side detection operating unit 2002 may be composed of, for example, a coil electrically connected to the forced-side switching unit 5101. In this case, the forced-side detection operating unit 2002 may be configured to switch the forced-side detection switching unit 2001 to the open state when it is energized by power flowing to the forced-side switching unit 5101, and to switch the forced-side detection switching unit 2001 to the closed state when the power flowing from the forced-side switching unit 5101 is interrupted and it is no longer energized.

[0084] In this embodiment, a single circuit (referred to as the forced circuit C1) is formed by the forced side detection operation unit 2002, the L1 phase input terminal 5000 and the L2 phase input terminal 5000 of the input terminal block unit 500, the forced side external terminal block unit 5020, and the forced side internal circuit 5100 and forced side switching unit 5101 of the forced side switching means 510. When the forced side switching unit 5101 is switched to the closed state while power is supplied to the breaker 5, power flows to the forced circuit C1, and when the forced side switching unit 5101 is switched to the open state, power to the forced circuit C1 is stopped.

[0085] Furthermore, in the forced circuit C1, fuse F1 is connected in series with the forced switch 5101. Therefore, in the forced circuit C1, if fuse F1 blows while power is being supplied, power will not flow regardless of the open / closed state of the forced switch 5101, and the forced switch 5101 will become de-energized.

[0086] The interruption-side detection means 201 is configured to notify that the interruption-side switching unit 5111 of the interruption-side switch means 511 is energized during the notification operation. In this embodiment, the interruption-side detection means 201 is configured to notify that the interruption-side switching unit 5111 is energized by changing its electrical state.

[0087] More specifically, the interruption-side detection means 201 includes an interruption-side connection circuit 2010 (see Figure 3) connected to the transmission means 3, an interruption-side detection switch 2011 electrically connected to the transmission means 3 via the interruption-side connection circuit 2010, and an interruption-side detection operation unit 2012 that switches the open / closed state of the interruption-side detection switch 2011 according to the energized state of the interruption-side switch means 511.

[0088] In the interruption detection means 201 of this embodiment, the notification operation is the operation in which the interruption detection opening / closing unit 2011 switches to the closed state.

[0089] Furthermore, the interruption detection means 201 is configured as an a-contact. Therefore, the interruption detection switching unit 2011 is in the off state when not receiving external operation, and is configured to switch from the off state to the on state when it receives external operation. The interruption detection switching unit 2011 is configured to return from the on state to the off state when the external operation is released.

[0090] The interruption-side detection switching unit 2011 in this embodiment is configured to be in the off state when the interruption-side switch means 511 is switched to a non-energized state, and to switch from the off state to the on state when the interruption-side switch means 511 is switched to an energized state.

[0091] Accordingly, the circuit breaker detection operation unit 2012 is configured to switch the circuit breaker detection opening / closing unit 2011 to the closed state when the circuit breaker switch means 511 switches from a non-energized state to an energized state, and to switch the circuit breaker detection opening / closing unit 2011 to the open state when the circuit breaker switch means 511 switches from an energized state to a non-energized state.

[0092] The interruption detection operating unit 2012 may also be composed of, for example, a coil electrically connected to the interruption side switching unit 5111. In this case, the interruption detection operating unit 2012 may be configured to switch the interruption detection switching unit 2011 to a closed state when it is energized by power flowing to the interruption side switching unit 5111, and to switch the interruption detection switching unit 2011 to an open state when the power flowing from the interruption side switching unit 5111 is interrupted and it is no longer energized.

[0093] In this embodiment, a single circuit (referred to as the breaker circuit C2) is formed by the breaker side detection operation unit 2012, the L1 phase input terminal 5000 and the L2 phase input terminal 5000 of the input terminal block unit 500, the breaker side external terminal block unit 5021, and the breaker side internal circuit 5110 and breaker side switching unit 5111 of the breaker side switch means 511. When power is supplied to the breaker 5, power flows to the breaker circuit C2 when the breaker side switching unit 5111 is switched to the closed state, and power to the breaker circuit C2 is stopped when the breaker side switching unit 5111 is switched to the open state.

[0094] Furthermore, in the interruption circuit C2, the fuse F2 is connected in series with the interruption switch 5111. Therefore, in the interruption circuit C2, if the fuse F2 blows while power is being supplied, power will not flow regardless of the open / closed state of the interruption switch 5111, and the interruption switch 5111 will become de-energized.

[0095] As described above, the detection means 2 of this embodiment is configured such that the forced-side opening / closing unit 5101, which is a b-contact, is combined with the forced-side detection opening / closing unit 2001, which is a b-contact, and the interruption-side opening / closing unit 5111, which is an a-contact, is combined with the interruption-side detection opening / closing unit 2011, which is an a-contact.

[0096] The transmitting means 3 includes a forced-side notification detection means 30 for detecting the notification operation of the forced-side detection means 200, a shut-off-side notification detection means 31 for detecting the notification operation of the shut-off-side detection means 201, and an output means 32 that outputs energization information indicating the state of the forced-side switch means 510 and the shut-off-side switch means 511 based on the detection state of the notification operation of the forced-side detection means 200 by the forced-side notification detection means 30 and the detection state of the notification operation of the shut-off-side detection means 201 by the shut-off-side notification detection means 31.

[0097] The output means 32 is configured to include forced-side non-powered information in the powered information if the forced-side notification detection means 30 has detected a notification operation of the forced-side detection means 200, and to include forced-side powered information in the powered information if the forced-side notification detection means 30 has not detected a notification operation of the forced-side detection means 200, and to include forced-side powered information in the powered information if the forced-side switch means 510 has been powered.

[0098] Furthermore, the output means 32 is configured to include interruption-side powered information in the powered information if the interruption-side notification detection means 31 has detected a notification operation of the interruption-side detection means 201, and to include interruption-side non-powered information in the powered information if the interruption-side notification detection means 31 has not detected a notification operation of the interruption-side detection means 201, and to include interruption-side non-powered information in the powered information if the interruption-side notification detection means 31 has not detected a notification operation of the interruption-side detection means 201, indicating that the interruption-side switch means 511 is not powered.

[0099] In this embodiment, the output means 32 is configured to output the power supply information to the discrimination means 4. Furthermore, the output means 32 only needs to be configured to output the power supply information to the discrimination means 4 via wireless communication or wired communication.

[0100] The discrimination means 4 includes a processing means 40 that acquires power supply information output from the output means 32 of the transmission means 3 and outputs a determination result of whether or not there is a power outage based on the power supply information, and outputs a determination result of the state of the circuit breaker 5 based on the power supply information. The output destination of the determination result by the discrimination means 4 may be, for example, a display device, or a device of a different type from a display device.

[0101] The processing means 40 may be configured, for example, to determine whether or not there is a power outage based on the forced power supply information, and to determine the state of the breaker 5 based on the interrupted power supply information.

[0102] The processing means 40 should be configured to output information indicating that no power outage has occurred if the power supply information includes forced power supply information, and to output information indicating that a power outage may have occurred if the power supply information includes forced non-power supply information.

[0103] Furthermore, the processing means 40 may be configured to output information indicating that no power outage has occurred as a determination result when the power supply information includes both forced power supply information and forced non-power supply information.

[0104] Furthermore, the processing means 40 should be configured to output information indicating that the breaker 5 has tripped as a determination result if the energization information includes information on the interruption side.

[0105] Furthermore, the processing means 40 may be configured to output information indicating that the breaker 5 has tripped as a determination result when the energization information includes both forced-side non-energization information and forced-side energization information.

[0106] As shown in Figure 4, if there is no power outage, the forced-side detection means 200 does not detect the de-energized state of the forced-side switching unit 5101. If there is a power outage, the forced-side detection means 200 detects the de-energized state of the forced-side switching unit 5101. Therefore, by monitoring the forced-side energized information and forced-side de-energized information, which change according to the operation of the forced-side detection means 200, it is possible to determine whether or not there is a possibility of a power outage.

[0107] Furthermore, if the breaker 5 has not tripped, the interruption-side detection means 201 has not detected the energized state of the interruption-side switching unit 5111. If the breaker 5 has tripped, the interruption-side detection means 201 has detected the energized state of the interruption-side switching unit 5111. Therefore, by monitoring the interruption-side energized information and interruption-side non-energed information, which change according to the operation of the interruption-side detection means 201, it is possible to determine whether or not the breaker 5 has tripped.

[0108] The configuration of the power outage detection system 1 according to this embodiment is as described above. Next, the operation of the power outage detection system 1 will be explained.

[0109] Referring to Figures 3 and 7, the operation of the power outage detection system 1 when power is supplied to breaker 5 and the main circuit of breaker 5 is closed will be explained.

[0110] In this case, in the forced-side switching means 510 of the breaker 5, the forced-side opening / closing part 5101, which is a normally closed contact, is not receiving operation from the forced-side operating mechanism and is switched to the closed state. When the forced-side detection operating part 2002 is energized, in the forced-side detection means 200 of the detection means 2, the forced-side detection opening / closing part 2001, which is a normally closed contact, is receiving operation from the forced-side detection operating part 2002 and is switched to the open state.

[0111] Furthermore, in the breaker 5's tripping switch mechanism 511, the tripping side opening / closing part 5111, which is an a-contact, is not receiving operation from the tripping side operating mechanism and is switched to the open state. At this time, the tripping side detection operating part 2012 is not energized, so in the tripping side detection means 201 of the detection means 2, the tripping side detection opening / closing part 2011, which is an a-contact, is not receiving operation from the forced side detection operating part 2002 and is switched to the open state.

[0112] Thus, when power is supplied to the breaker 5 and the main circuit of the breaker 5 is closed, the forced-side detection means 200 does not perform a notification operation, and the interruption-side detection means 201 also does not perform a notification operation. Therefore, the transmitting means 3 outputs the power supply information, including the forced-side power supply information and the interruption-side power supply information, to the discrimination means 4 via the output means 32.

[0113] The processing means 40, having acquired this power supply information, then determines, based on the power supply information, that the main circuit is closed and power is being supplied to the breaker normally (i.e., no power outage has occurred).

[0114] When the main circuit of breaker 5 is closed, if a power outage occurs (the power supply to breaker 5 is interrupted), as shown in Figures 4 and 7, the forced-side switch mechanism 510 of breaker 5 has a normally closed (b) contact, the forced-side switching unit 5101, which is not being operated by the forced-side operating mechanism and remains switched to the closed state. On the other hand, the forced-side detection operation unit 2002 switches from a powered state to a non-powered state, so the forced-side detection operation unit 2001 of the detection means 2 has its normally closed (b) contact released from the forced-side detection operation unit 2002 and switches from the open state to the closed state.

[0115] In the circuit breaker 5's tripping switch mechanism 511, the tripping side opening / closing part 5111, which is an a-contact, remains switched to the open state because it has not been operated by the tripping side operating mechanism. Therefore, in the detection means 201 of the detection means 2's tripping side detection opening / closing part 2011, which is an a-contact, also remains switched to the open state because it has not been operated by the tripping side detection operating part 2012.

[0116] Furthermore, as shown in Figures 5 and 7, when the main circuit of the breaker 5 is forcibly switched to an open state while power is being supplied to the breaker 5, the forced-side switching unit 5101, which is a b-contact, switches from a closed state to an open state in response to the operation from the forced-side operating mechanism. Consequently, the excitation state of the forced-side detection operating unit 2002 is released, and the forced-side detection switching unit 2001, which is a b-contact, switches from an open state to a closed state as the operation from the forced-side detection operating unit 2002 is released.

[0117] In the circuit breaker 5's tripping switch mechanism 511, the tripping side opening / closing part 5111, which is an a-contact, remains switched to the open state because it has not been operated by the tripping side operating mechanism. Therefore, in the detection means 201 of the detection means 2's tripping side detection opening / closing part 2011, which is an a-contact, also remains switched to the open state because it has not been operated by the tripping side detection operating part 2012.

[0118] Thus, whether a power outage occurs when the main circuit of breaker 5 is closed, or when the main circuit of breaker 5 is forcibly switched to an open state while power is being supplied to breaker 5, the forced-side detection means 200 performs a notification operation, while the interruption-side detection means 201 does not. Therefore, the transmitting means 3 outputs power information, including forced-side non-power information and interruption-side non-power information, to the discrimination means 4 via the output means 32.

[0119] In the determination means 4 that has acquired such power supply information, the processing means 40 determines that there is a possibility of a power outage based on the forced non-power supply information of the power supply information.

[0120] Furthermore, even if the fuse F1 of the forced circuit C1 blows while power is being supplied to breaker 5 and the main circuit of breaker 5 is switched to the closed state, the forced side switching unit 5101 remains in the closed state, the forced side detection operation unit 2002 switches from energized to de-energized information, and the forced side detection switching unit 2001, which is a b-contact, switches from the open state to the closed state. On the other hand, since the electrical state of the interruption side circuit C2 does not change, the interruption side detection means 201 of the detection means 2 remains switched to the open state, with the interruption side detection switching unit 2011, which is an a-contact, remaining open.

[0121] Therefore, in this case as well, the discrimination means 4 determines that the processing means 40 may be experiencing a power outage based on the forced non-power information of the power supply information.

[0122] Furthermore, if the main circuit, which has been switched to the forcibly open state, is returned to the closed state, the forced-side switching mechanism 510 of the breaker 5 returns the forced-side switching unit 5101, which is a b-contact, from the open state to the closed state as the operation from the forced-side operating mechanism is released. Then, if the forced-side detection operation unit 2002 is switched to an energized state, the forced-side detection mechanism 200 of the detection mechanism 2 receives an operation from the forced-side detection operation unit 2002 and switches the forced-side detection switching unit 2001 from the closed state to the open state.

[0123] Thus, since power is supplied to breaker 5 and the main circuit of breaker 5 returns to a closed state, the determination means 4 determines that the processing means 40 has not experienced a power outage based on the forced power supply information of the power supply information.

[0124] Next, we will explain the operation of the power outage detection system 1 when the main circuit of breaker 5 switches from a closed state to an open state (i.e., when breaker 5 trips) while power is being supplied to breaker 5.

[0125] In this case, as shown in Figures 6 and 7, in the forced-side switch mechanism 510 of the breaker 5, the forced-side opening / closing part 5101, which is a b-contact, is switched from the closed state to the open state by an operation from the forced-side operating mechanism. Consequently, the excitation state of the forced-side detection operation part 2002 is released, so in the forced-side detection means 200 of the detection means 2, the forced-side detection opening / closing part 2001, which is a b-contact, is released from the operation from the forced-side detection operation part 2002 and switches from the open state to the closed state.

[0126] In the breaker 5's tripping switch mechanism 511, the tripping side opening / closing part 5111, which is an a-contact, switches from the open state to the closed state in response to an operation from the tripping side operating mechanism. Consequently, the tripping side detection operating part 2012 switches to the energized state, and in the detection means 2's tripping side detection means 201, the tripping side detection opening / closing part 2011, which is an a-contact, also switches from the open state to the closed state in response to an operation from the tripping side detection operating part 2012.

[0127] Thus, if the breaker 5 trips while power is being supplied to it, the enforcement-side detection means 200 performs a notification operation, and the interruption-side detection means 201 also performs a notification operation. Therefore, the transmission means 3 outputs the power supply information, including the enforcement-side non-power supply information and the interruption-side power supply information, to the discrimination means 4 via the output means 32.

[0128] The processing means 40, having acquired this power supply information, then determines, based on the power supply information, that a trip has occurred.

[0129] Furthermore, if the circuit breaker 5 trips while power is being supplied to it, and then the fuse F2 blows, the circuit breaker 5's interruption switch mechanism 511 will remain closed, and the circuit breaker detection operation unit 2012 will switch from energized to de-energized. In the circuit breaker detection mechanism 201 of the detection mechanism 2, the circuit breaker detection switch 2011, which is an a-contact, will switch from closed to open. On the other hand, since the electrical state of the forced circuit C1 does not change, the forced detection mechanism 200 of the detection mechanism 2 will remain switched to closed, with the forced detection switch 2001, which is a b-contact, remaining closed.

[0130] In this case, the determination result by the processing means 40 changes from trip to possible power outage in the determination means 4.

[0131] Furthermore, if the main circuit, which has been switched to the open state, is returned to the closed state, the forced-side switching unit 5101, which is a b-contact, in the forced-side switching means 510 of the breaker 5 returns from the open state to the closed state as the operation from the forced-side operating mechanism is released. Then, if the forced-side detection operation unit 2002 is switched to an energized state, the forced-side detection switching unit 2001, which is a b-contact, in the forced-side detection means 200 of the detection means 2 receives operation from the forced-side detection operation unit 2002 and switches from the closed state to the open state.

[0132] Furthermore, the normally open (a) contact, the interruption-side opening / closing unit 5111, returns from the closed state to the open state when the operation from the interruption-side operating mechanism is released. Consequently, the excitation state of the interruption-side detection operating unit 2012 is released, and in the interruption-side detection means 201 of the detection means 2, the normally open (a) contact, the interruption-side detection opening / closing unit 2011, switches from the closed state to the open state when the operation from the interruption-side detection operating unit 2012 is released.

[0133] Thus, since power is supplied to breaker 5 and the main circuit of breaker 5 returns to a closed state, the determination means 4 determines that the processing means 40 has not experienced a power outage based on the forced power supply information of the power supply information.

[0134] As described above, according to the detection means 2 (detection device) of this embodiment, the energization status of the switch means 51 can be detected by the energization detection means 20, and the power outage situation can be confirmed based on the presence or absence of current flowing through the switch means 51, thus providing the excellent effect of being useful in dealing with power outage accidents.

[0135] Furthermore, by combining the detection means 2 of this embodiment with the transmission means 3, which transmits the detection result of the power supply status of the switch means 51 by the power supply detection means 20, into a detection unit, the transmission means 3 can transmit the detection result of the power supply status of the switch means 51 by the power supply detection means 20 of the detection means 2 to an external source. This makes it possible to confirm the power outage state externally (outside the detection unit) based on the presence or absence of current flowing through the switch means 51.

[0136] Furthermore, the power outage detection system 1 of this embodiment includes the detection means 2 and a determination means 4 that performs a process to determine the power outage state of the breaker 5 based on the detection result of the power supply state of the switch means 51 by the power supply detection means 20. Therefore, the power outage status can be confirmed based on the presence or absence of current flowing through the switch means 51, and the power outage status can be confirmed even at a location far from where the detection means 2 is installed, thanks to the inclusion of a transmission means 3.

[0137] Furthermore, the detection means 2 can also be configured by introducing a detection program for a circuit breaker 5 into a computer, which functions as a detection device for the circuit breaker 5. The circuit breaker 5 includes an input terminal 5000 into which power is input, an output terminal 5010 that outputs power, a main circuit connecting the input terminal 5000 and the output terminal 5010, and a switch means 51 whose energized state switches in conjunction with at least two of the following states: a closed state in which the main circuit is closed, a forced open state in which the main circuit is opened by external power, and a tripped open state in which the main circuit is opened using the power flowing through the main circuit as power. If such a detection program for a circuit breaker 5 is configured such that the computer functioning as the detection device is equipped with an energized detection means 20 that detects the energized state of the switch means 51, then by making the computer function as a detection device, it becomes possible to confirm the power outage state based on the detection result of the energized state of the switch means 51 by the energized detection means 20.

[0138] Furthermore, in this embodiment, a method for detecting the energized state of the switch means 51 of the breaker 5 by the operation of the power outage detection system 1 (i.e., a detection method for the breaker 5) has been described. However, as in the operation of the power outage detection system 1, if the energized state of the switch means 51 is detected for a breaker 5 that includes an input terminal 5000 into which power is input, an output terminal 5010 that outputs power, a main circuit connecting the input terminal 5000 and the output terminal 5010, and a switch means 51 whose energized state switches in conjunction with at least two of the following states: a closed state in which the main circuit is closed, a forced open state in which the main circuit is opened by external power, and a tripped open state in which the main circuit is opened using the power flowing through the main circuit as power, then the power outage can be confirmed based on the detection result of the energized state of the switch means 51.

[0139] It should be noted that the detection device, detection unit, power outage detection system, detection program, and detection method for circuit breakers according to the present invention are not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the present invention.

[0140] In the power outage detection system 1 of the above embodiment, the detection means 2 and the transmission means 3 were configured as separate devices, but the system is not limited to this configuration. For example, the detection means 2 and the transmission means 3 may be configured as a single device.

[0141] In the circuit breaker 5 of the above embodiment, the switch means 51 was configured to switch its conduction state in conjunction with the operation of switching the main circuit to a closed state, an open state, and an open state, but it is not limited to this configuration. For example, the switch means 51 may be configured to switch its energized state in conjunction with the operation of switching the main circuit to a closed state and an open state.

[0142] Although not specifically mentioned in the above embodiments, the mechanism for switching the open / closed state of the main circuit may be configured to include a mechanism for switching the main circuit to a forcibly open state and a mechanism for switching the main circuit to a tripped-open state, or the mechanism for switching the main circuit to a forcibly open state and the mechanism for switching the main circuit to a tripped-open state may be configured by a single mechanism.

[0143] In the power outage detection system 1 of the above embodiment, the forced-side detection means 200 was configured to notify that the forced-side switching unit 5101 was in a de-energized state by changing its electrical state, but the system is not limited to this configuration. For example, the forced-side detection means 200 may be configured to notify that the forced-side switching unit 5101 is in a de-energized state by information communication.

[0144] In this case, the enforcement-side notification detection means 30 may be configured to directly acquire information output from the enforcement-side detection means 200, or it may be configured to read information stored in a storage device after it has been output from the enforcement-side detection means 200 (i.e., it may be configured to acquire information output from the enforcement-side detection means 200 directly or indirectly).

[0145] Similarly, the interruption-side detection means 201 was configured to notify that the interruption-side switching unit 5111 was in a de-energized state by changing its electrical state. However, for example, the interruption-side detection means 201 may be configured to notify that the interruption-side switching unit 5111 is in a de-energized state by information communication.

[0146] In this case as well, the blocking side notification detection means 31 may be configured to directly acquire information output from the blocking side detection means 201, or it may be configured to read information stored in a storage device after it has been output from the blocking side detection means 201 (i.e., it may be configured to acquire information output from the blocking side detection means 201 directly or indirectly).

[0147] Although not specifically mentioned in the above embodiment, the processing means 40 may be configured to directly acquire information output by the output means 32, or it may be configured to acquire information stored in the storage means after it has been output from the output means 32 (i.e., it may be configured to acquire information output from the output means 32 directly or indirectly).

[0148] Although not specifically mentioned in the above embodiment, the enforcement-side detection means 200 may be configured to continuously emit a signal indicating that the enforcement-side switch means 510 is in a de-energized state during the notification operation, or it may be configured to emit a signal indicating that the enforcement-side switch means 510 is in a de-energized state at the timing of the notification operation.

[0149] Furthermore, although the power outage detection system of the above embodiment was configured to output a signal when the enforcement-side detection means 200 notifies that the enforcement-side switch means 510 is in a non-powered state, the system may be configured to output a signal when the enforcement-side detection means 200 has not notified that the enforcement-side switch means 510 is in a non-powered state, and to stop outputting the signal when the enforcement-side detection means 200 notifies that the enforcement-side switch means 510 is in a non-powered state. Alternatively, the system may be configured to output different signals depending on whether the enforcement-side detection means 200 has not notified that the enforcement-side switch means 510 is in a non-powered state or whether the enforcement-side detection means 200 has notified that the enforcement-side switch means 510 is in a non-powered state.

[0150] In the above embodiment, the forced-side switch means 510 was electrically connected to the uppermost output terminal 5020a and the lowermost output terminal 5020c of the three output terminals 5020a, 5020b, and 5020c of the forced-side external terminal block 5020, but the configuration is not limited to this. For example, the forced-side switch means 510 may be electrically connected to the central output terminal 5020b and the lowermost output terminal 5020c of the three output terminals 5020a, 5020b, and 5020c of the forced-side external terminal block 5020.

[0151] In this way, when the forced-side switch means 510 is switched to the ON state, the terminals between output terminals 5020b and 5020c of the forced-side external terminal block 5020 become non-conductive, and when the forced-side switch means 510 is switched to the OFF state, the terminals between output terminals 5020b and 5020c of the forced-side external terminal block 5020 become conductive.

[0152] Similarly, the interruption-side detection means 201 may be configured to continuously emit a signal indicating that the interruption-side switch means 511 is energized during the notification operation, or it may be configured to emit a signal indicating that the interruption-side switch means 511 is energized at the time the notification operation is performed.

[0153] Furthermore, although the power outage detection system of the above embodiment was configured to output a signal when the interruption-side detection means 201 notifies that the interruption-side switch means 511 is in a non-energized state, the system may be configured to output a signal when the interruption-side detection means 201 has not notified that the interruption-side switch means 511 is in a non-energized state, and to stop outputting the signal when the interruption-side detection means 201 notifies that the interruption-side switch means 511 is in a non-energized state. Alternatively, the system may be configured to output different signals depending on whether the interruption-side detection means 201 has not notified that the interruption-side switch means 511 is in a non-energized state or whether the interruption-side detection means 201 has notified that the interruption-side switch means 511 is in a non-energized state.

[0154] In the above embodiment, the interruption-side switch means 511 was electrically connected to the lowermost output terminal 5021c and the uppermost output terminal 5021a of the three output terminals 5021a, 5021b, and 5021c of the interruption-side external terminal block 5021, but the configuration is not limited to this. For example, the interruption-side switch means 511 may be electrically connected to the middle output terminal 5021b and the lowermost output terminal 5021c of the three output terminals 5021a, 5021b, and 5021c of the interruption-side external terminal block 5021.

[0155] In this way, when the interruption-side switch means 511 is switched to the ON state, the terminals between output terminal 5021b and output terminal 50211c of the interruption-side external terminal block 5021 become non-conductive, and when the interruption-side switch means 511 is switched to the OFF state, the terminals between output terminal 5021b and output terminal 5021c of the interruption-side external terminal block 5021 become conductive.

[0156] In the above embodiment, the forced-side detection means 200 detected that the forced-side switch means 510 (forced-side switching unit 5101) was energized, but the configuration is not limited to this. For example, the forced-side detection means 200 may be configured to detect that the forced-side switch means 510 (forced-side switching unit 5101) was not energized. More specifically, the forced-side detection switching unit 2001 may be configured as an normally open (a) contact.

[0157] When this configuration is adopted, the forced-side detection means 200 detects the energized state of the forced-side switch means 510. As shown in Figure 8, if there is no power outage, the forced-side detection means 200 detects the energized state of the forced-side switch 5101, and if there is a power outage, the forced-side detection means 200 does not detect the energized state of the forced-side switch 5101. Therefore, by monitoring the forced-side energized information and forced-side non-energized information, which change according to the operation of the forced-side detection means 200, it is possible to determine whether or not there is a possibility of a power outage.

[0158] In the above embodiment, the interruption-side detection means 201 detected that the interruption-side switch means 511 (interruption-side switching unit 5111) was energized, but the configuration is not limited to this. For example, the interruption-side detection means 201 may be configured to detect that the interruption-side switch means 511 (interruption-side switching unit 5111) is not energized. More specifically, the interruption-side detection switching unit 2011 may be configured as a normally closed (b) contact.

[0159] When this configuration is adopted, the interruption-side detection means 201 detects the de-energized state of the interruption-side switch means 511. As shown in Figure 9, if the breaker 5 has not tripped, the interruption-side detection means 201 detects the de-energized state of the interruption-side switch 5111. If the breaker 5 has tripped, the interruption-side detection means 201 detects the de-energized state of the interruption-side switch 5111. Therefore, by monitoring the interruption-side energized information and interruption-side de-energized information, which change according to the operation of the interruption-side detection means 201, it is possible to determine whether or not the breaker 5 has tripped.

[0160] Furthermore, it is also possible to configure the forced-side detection switch 2001 as an a-contact and the tripping-side detection switch 2011 as a b-contact. In this case as well, as shown in Figure 10, by monitoring the forced-side energization information and forced-side de-energization information, which change according to the operation of the forced-side detection means 200, it is possible to determine whether or not a power outage is likely to have occurred. Similarly, by monitoring the tripping-side energization information and tripping-side de-energization information, which change according to the operation of the tripping-side detection means 201, it is possible to determine whether or not the breaker 5 has tripped.

[0161] In the above embodiment, the circuit breaker 5 to which the detection device is connected had a normally closed (b) contact for the forced-side switching unit 5101 and a normally closed (a) contact for the interruption-side switching unit 5111, but the configuration is not limited to this. For example, the circuit breaker 5 to which the detection device is connected may have a normally closed (a) contact for the forced-side switching unit 5101 and a normally closed (b) contact for the interruption-side switching unit 5111. The operation pattern of the power outage detection system in this case is shown in Figure 11.

[0162] Furthermore, even if the breaker 5 to which the detection device is connected has a normally open (a) contact for the forced-side switching unit 5101 and a normally closed (b) contact for the interruption-side switching unit 5111, it is still possible to configure the forced-side detection switching unit 2001 as a normally open (a) contact. The operation pattern of the power outage detection system in this case is shown in Figure 12.

[0163] Furthermore, even if the breaker 5 to which the detection device is connected has a normally open (a) contact for the forced-side switching unit 5101 and a normally closed (b) contact for the interruption-side switching unit 5111, it is also possible to configure the interruption-side detection switching unit 2011 as a normally closed (b) contact. The operation pattern of the power outage detection system in this case is shown in Figure 13.

[0164] Furthermore, even if the breaker 5 to which the detection device is connected has a normally open (a) contact for the forced-side switching unit 5101 and a normally closed (b) contact for the interruption-side switching unit 5111, it is also possible to configure the forced-side detection switching unit 2001 as a normally open (a) contact and the interruption-side detection switching unit 2011 as a normally closed (b) contact. The operation pattern of the power outage detection system in this case is shown in Figure 14.

[0165] Even when the power outage detection system follows the operating patterns shown in Figures 11 to 14, monitoring the forced-side power supply information and forced-side non-power supply information, which change according to the operation of the forced-side detection means 200, makes it possible to determine whether or not a power outage is likely to have occurred. Furthermore, monitoring the interruption-side power supply information and interruption-side non-power supply information, which change according to the operation of the interruption-side detection means 201, makes it possible to determine whether or not the breaker 5 has tripped.

[0166] Furthermore, because the combinations of forced-side power supply information, forced-side power supply information, interrupted-side power supply information, and interrupted-side power supply information differ depending on whether the main circuit is closed and the breaker is receiving power normally, whether the main circuit is forcibly switched to an open state, whether the main circuit is interrupted and open, or whether a power outage is occurring, it is possible to reliably determine whether a power outage has occurred.

[0167] In the above embodiment, separate fuses F1 and F2 were connected to the enforcement circuit C1 and the interruption circuit C2, respectively, but the configuration is not limited to this. For example, a single fuse may be connected to both the enforcement circuit C1 and the interruption circuit C2 as a common connection.

[0168] In this configuration, when the fuse blows, power will not flow to the forced circuit C1 and the interrupted circuit C2. As a result, the forced switching unit 5101 and the interrupted switching unit 5111 that are energized will switch to an unenergized state, and the forced detection means 200 and the interrupted detection means 201 that are performing a notification operation will stop their notification operation.
