How to Improve the Electrical Safety Level of Flood Protection of Outdoor Cabinets

Abstract

The invention particularly relates to a method for improving flood-control electric safety level of an outdoor cabinet. Through the method, a main breaker is installed on the upper portion of the outdoor cabinet; double water level sensors composed of a low water level sensor and a high water level sensor are utilized, wherein the low water level sensor is installed on the lower portion of the outdoor cabinet and used for detecting whether water enters the outdoor cabinet and sending warning messages to users through a monitoring platform in advance, and the high water level sensor is installed at a certain height of the outdoor cabinet according to the flood control level which the users require. When the high water level sensor detects that the water reaches a set height, the main breaker is turned off, and the whole outdoor cabinet is powered off. The method has the advantages that by the adoption of the mechanical control and electric control combined method, the flood control height of the outdoor cabinet can be automatically regulated, the flood control capacity of the outdoor cabinet is strong, and the internal electric source of the outdoor cabinet can be automatically turned off when the water level reaches the flood control height; when the water level does not reach the height of the breaker, the water is electrically neutral, and therefore personal safety is effectively protected; the outdoor cabinet is simple, low in cost and applicable to large-scale popularization and application.

Description

technical field [0001] The invention belongs to the field of electrical equipment safety protection, and in particular relates to a method for improving the electrical safety level of outdoor cabinet flood protection. Background technique [0002] The outdoor cabinet is mainly suitable for the installation and protection of outdoor local control and protection devices. It has the functions of dustproof, waterproof, anti-corrosion, anti-electromagnetic interference, heat insulation, cold protection, and anti-condensation. [0003] However, the large outdoor cabinets currently on the market generally do not have flood protection capabilities, and only a few small outdoor cabinets use mechanical protection such as IP66 to achieve certain flood protection capabilities, but the cost is extremely high and implementation is difficult. The mechanical protection type flood control method is expensive for slightly larger outdoor cabinets and cannot be promoted on a large scale. There...

[0003] However, the large outdoor cabinets currently on the market generally do not have flood protection capabilities, and only a few small outdoor cabinets use mechanical protection such as IP66 to achieve certain flood protection capabilities, but the cost is extremely high and implementation is difficult.

The mechanical protection type flood control method is expensive for slightly larger outdoor cabinets and cannot be promoted on a large scale

Therefore, the general outdoor cabinets only have cabinet water ingress alarms. Once natural disasters such as floods occur, the cabinet power supply cannot be automatically cut off in time, and the equipment in the cabinet will be damaged. The charged flood will bring life safety to nearby people.
