Low-voltage power distribution cabinet with pre-alarm device, and monitoring system applying same

Abstract

The invention discloses a low-voltage power distribution cabinet with a pre-alarm device, and a monitoring system applying the low-voltage power distribution cabinet. The low-voltage cabinet comprisesa cabinet body, wherein a cabinet door is hinged to the cabinet body, a blowing fan communicated with the interior of the cabinet body is arranged on the side surface of the outer portion of the cabinet body, an electric heating tube is arranged at the intersection of the blowing fan and the side wall of the cabinet body, the cabinet body is also provided with a pre-alarm device, the pre-alarm device comprises a main controller, a temperature and humidity sensor, a smoke sensor, a clinometer, a wireless communication module and a GPS positioning module, the temperature and humidity sensor, the smoke sensor, the clinometer, the wireless communication module and the GPS positioning module are respectively connected with the main controller, the main controller is in control connection withthe blowing fan and the electric heating tube, and a water level sensing device is arranged outside the cabinet body. According to the invention, the internal and external environments of the power distribution cabinet can be detected, and early warning information can be sent out.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a low-voltage power distribution cabinet with a pre-alarm device and a monitoring system using the same. Background technique [0002] With the continuous development of construction projects, the requirements of all walks of life for the construction site of construction projects are also increasing, and the requirements for the safety of electricity use are also getting higher and higher. [0003] At present, most power distribution cabinets are installed outdoors. In summer and other weather prone to rainstorms, or in areas with frequent storms, the location of the outdoor distribution cabinet is prone to water accumulation or high humidity. When the accumulation of water is deep, the accumulation of water may enter the outdoor power distribution cabinet. The cabinet will cause damage to the outdoor power distribution cabinet, or cause a safety accident, and even cause an ex...

AI Technical Summary

Problems solved by technology

In summer and other weather prone to rainstorms, or in areas with frequent storms, the location of the outdoor distribution cabinet is prone to water accumulation or high humidity. When the accumulation of water is deep, the accumulation of water may enter the outdoor power distribution cabinet. The cabinet will cause damage to the outdoor power distribution cabinet, or cause a safety accident, and even cause an explosion in severe cases

[0004] The setting of the power distribution cabinet must be far away from the fire source, but outdoors, the location of the fire is uncontrollable, especially in some mountainous areas, these places are densely wooded, and once a fire breaks out, it will be difficult to control it. Unable to accurately know the location of the power distribution cabinet where the fire occurred and remind the power personnel, incalculable losses will occur

[0005] The power distribution cabinet installed outdoors is prone to inclination due to the influence of natural and man-made environments. If it is not handled in time, it is easy to cause accidents
