Description

Technical Field

[0001] This utility model belongs to the field of monitoring technology for navigation light power distribution systems, and more specifically, relates to a power failure alarm device for a navigation light power distribution system. Background Technology

[0002] As a primary load at airports, the low-voltage power distribution system for navigation lights typically employs a combined power supply mode consisting of dual mains power (primary power), diesel generator sets (backup power), and UPS (uninterruptible power supply). When any primary power source fails, the backup power source must quickly switch over to ensure continuous power supply to runway and taxiway lights. However, the existing system has the following problems:

[0003] Risk of delayed backup power switching: If the backup power fails to be put into operation in time, the runway lights in the power-out section will be directly interrupted, threatening flight safety.

[0004] Delayed fault detection: Traditional monitoring relies on manual inspections, and alarm signals are often buzzers, which may be affected by environmental noise, making it impossible to locate power failure faults in real time, resulting in processing delays. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a power failure alarm device for a navigation light power distribution system. This device solves the problems of existing technologies lacking an active, segmented alarm mechanism for monitoring power failures in navigation light power distribution systems, making it difficult to reliably receive alarm signals and quickly locate the fault.

[0006] To achieve the above objectives, this utility model provides a power failure alarm device for a navigation light power distribution system, wherein the navigation light power distribution system includes a three-phase busbar, comprising:

[0007] The enclosure has an openable and closable panel, a circuit breaker and a relay are installed inside the enclosure, and an audible and visual alarm and a selector switch are installed on the outside of the panel.

[0008] Each phase busbar is divided into multiple monitoring sections, and each monitoring section is equipped with a circuit breaker and a relay.

[0009] Multiple monitoring buses, each monitoring bus connected to one of the relays, and each monitoring bus is equipped with an audible and visual alarm and a changeover switch.

[0010] Optionally, the relay is a normally open relay, with the coil side of the normally open relay located in the monitoring section and the switch side of the normally open relay connected to the monitoring bus.

[0011] Optionally, each of the monitoring segments is equipped with a fuse.

[0012] Optionally, a resistor is provided on each of the monitoring buses.

[0013] Optionally, the monitoring bus is connected to a monitoring power supply or a UPS.

[0014] Optionally, the monitoring power supply is a 220V monitoring power supply.

[0015] Optionally, the UPS is a 220V UPS.

[0016] Optionally, the circuit breaker is a 1P circuit breaker with overload protection.

[0017] Optionally, the changeover switch is a single-pole 220V switch.

[0018] Optionally, it also includes a control unit connected to the monitoring bus, the control unit being equipped with a communication module for sending remote alarm signals.

[0019] This utility model provides a power failure alarm device for a navigation light power distribution system. Its advantages are as follows: This power failure alarm device integrates a circuit breaker, relay, audible and visual alarm, and changeover switch within a housing and its panel, forming a modular device. The busbar of the navigation light power distribution system is segmented, and a circuit breaker and relay are installed in each monitoring segment of the three-phase busbar to enable segmented monitoring of the busbar, thereby achieving rapid fault location. The relays and audible and visual alarms are connected to multiple monitoring busbars, and the monitoring busbars are independently connected to the three-phase busbars of the navigation light power distribution system. The system establishes an independent power supply for power outage alarms. Each audible and visual alarm on the monitoring bus corresponds to a relay on a monitoring section. The relay monitors the power outage status of each monitoring section, and when a power outage occurs, the corresponding audible and visual alarm emits an audible and visual alarm signal. The dual alarm of sound and light can weaken the influence of environmental noise on the alarm signal and improve the alarm effect. Furthermore, the setting of the transfer switch allows each audible and visual alarm to be reset through its corresponding transfer switch, which is convenient for resetting the standby state of the audible and visual alarm in the case of active operation of its opening and closing during three-phase bus maintenance.

[0030] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0031] like Figures 1 to 6 As shown, this utility model provides a power failure alarm device for a navigation light power distribution system. The navigation light power distribution system includes a three-phase busbar 1, comprising:

[0032] Box 2, Box 2 is equipped with an openable and closable panel 3, Box 2 is equipped with a circuit breaker 4 and a relay 13, and the outside of the panel 3 is equipped with an audible and visual alarm 7 and a changeover switch 8.

[0033] Each phase busbar is divided into multiple monitoring sections 9, and each monitoring section 9 is equipped with a circuit breaker 4 and a relay 13;

[0034] Multiple monitoring buses 10, each monitoring bus 10 is connected to a relay 13, and each monitoring bus 10 is equipped with an audible and visual alarm 7 and a changeover switch 8.

[0035] Specifically, to address the problem that existing technologies lack an active, segmented alarm mechanism for monitoring power outages in navigation light power distribution systems, making it difficult to reliably receive alarm signals and quickly locate faults, this utility model provides a power outage alarm device for navigation light power distribution systems. This device integrates a circuit breaker 4, a relay 13, an audible and visual alarm 7, and a changeover switch 8 within a housing 2 and its panel 3, forming a modular device. The busbars of the navigation light power distribution system are segmented, with a circuit breaker 4 and a relay 13 installed in each monitoring segment 9 of the three-phase busbar 1 to enable segmented monitoring of the busbars and thus rapid fault location. The relay 13 and the audible and visual alarm 7 are connected to multiple monitoring busbars 10. The monitoring bus 10 is independent of the three-phase bus 1 of the navigation light power distribution system, forming an independent power supply for power failure alarm. Each audible and visual alarm 7 on the monitoring bus 10 corresponds to a relay 13 on a monitoring section 9. The relay 13 is used to monitor the power failure status of each monitoring section 9, and when a power failure occurs, the corresponding audible and visual alarm 7 will issue an audible and visual alarm signal. The dual alarm of sound and light can weaken the influence of environmental noise on the alarm signal and improve the alarm effect. In addition, the setting of the changeover switch 8 allows each audible and visual alarm 7 to be reset through its corresponding changeover switch 8, which is convenient to reset the standby state of the audible and visual alarm 7 when the three-phase bus 1 is actively operated for maintenance.

[0036] In this embodiment, each phase monitoring bus 10 is divided into 4 monitoring segments 9, and the monitoring bus 10 is equipped with 12 segments.

[0037] In this embodiment, 12 audible and visual alarms 7 are arranged in two rows on the panel 3. Below each row of audible and visual alarms 7 is a row of changeover switches 8. Each changeover switch 8 corresponds to one audible and visual alarm 7 above it and is used to reset it for easy observation and reset.

[0038] In this embodiment, one side of the panel is rotatably connected to one side of the housing via a hinge, enabling it to be opened and closed. The other side of the panel is equipped with a door lock, which can cooperate with the bent part on the other side of the housing to lock the panel.

[0039] Optionally, relay 13 is a normally open relay, with the coil side 5 of the normally open relay located in the monitoring section 9, and the switch side 6 of the normally open relay connected to the monitoring bus.

[0040] Specifically, a normally open relay is used, and its coil side 5 senses the power outage status of the monitoring section 9 in the three-phase bus 1 of the navigation light power distribution system. When a monitoring section 9 is de-energized, the switch side 6 on the corresponding monitoring bus is closed, thereby powering on the audible and visual alarm 7 to emit an audible and visual alarm signal.

[0041] Optionally, each monitoring segment 9 is equipped with a fuse 11.

[0042] Specifically, fuse 11 provides protection for each monitoring segment 9.

[0043] Optionally, a resistor 12 is provided on each monitoring bus 10.

[0044] Specifically, resistor 12 forms a load on each monitoring bus 10.

[0045] Optionally, the monitoring bus 10 is connected to a monitoring power supply or a UPS.

[0046] Specifically, the monitoring bus 10 adopts a three-phase bus 1 power supply independent of the navigation light power distribution system, so as to avoid alarm failure due to main power failure and improve the stability and reliability of power failure alarm.

[0047] Optionally, the monitoring power supply is a 220V monitoring power supply.

[0048] Optionally, the UPS is a 220V UPS.

[0049] In this embodiment, the monitoring power supply line formed by the monitoring bus 10 is integrated into the enclosure 2, and the monitoring bus 10 uses 1.5 square millimeter single-strand copper sheathed wire.

[0050] In this embodiment, the cables inside the housing 2 are routed through cable trays, and the housing 2 is equipped with a terminal block 14.

[0051] Optionally, circuit breaker 4 is a 1P circuit breaker 4 with overload protection.

[0052] Specifically, each monitoring section 9 uses an independent 1P circuit breaker 4 with overload protection, which integrates the function of the fuse 11 and facilitates segmented control of each phase bus.

[0053] Optionally, the changeover switch 8 is a single-pole 220V switch.

[0054] Specifically, the changeover switch 8 is initially set to automatic mode to monitor the power outage status of the navigation light power distribution system in real time. The power outage alarm device for the navigation light power distribution system is installed in the airport's on-site duty room. The audible and visual alarm 7 and the changeover switch 8 are installed on the panel 3 on the housing 2 for easy observation and operation. When a power outage occurs in a certain monitoring segment 9, causing the corresponding navigation light to lose power, the indicator light of the audible and visual alarm 7 lights up red and flashes, and the buzzer emits a buzzing alarm sound. The duty personnel can confirm the location of the fault and switch to the backup power supply in time to restore power. Afterwards, the duty personnel manually operate the corresponding changeover switch 8 to reset the alarm, so that the audible and visual alarm 7 no longer emits audible and visual alarm signals.

[0055] Optionally, it also includes a control unit, which is connected to the monitoring bus 10. The control unit is equipped with a communication module for sending remote alarm signals.

[0056] Specifically, the control unit is configured to remotely transmit the power outage status monitored by the switch side 6 of the relay 13 on the monitoring bus 10 through the communication module. While issuing audible and visual alarm signals on site, it can also send remote alarm signals to the mobile terminal through the communication module, thereby improving remote monitoring capabilities.

[0057] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
