Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a power failure wireless remote alarm device for a distribution box. Background Art

[0002] In construction site production, distribution boxes (cabinets) often trip and power outages due to various reasons. If the corresponding management personnel cannot know about the power outage in the first time, it will have different degrees of impact on production and life, such as elevators cannot run, water pumps cannot pump water, and offices cannot work normally. The current power outage alarm technology is to install a set of alarm speakers (alarm speakers) next to the distribution cabinet. When a circuit in the cabinet is powered off, an alarm signal is sent out through an electrical interlocking relationship. The device can serve as a reminder within a certain range (within 500 square meters), and it will not serve as an alarm warning beyond the sound propagation range; when the noise on the construction site is too loud or there are no staff around, the warning effect is also limited.
