Embodiment: the present embodiment relates to a kind of method improving flood-control electric safety level of outdoor cabinet, a kind of method automatically cutting off general supply when running into flood specifically, the process employs the design of two level sensor, by the mode that machinery and electrical control are combined, outdoor cabinet internal electric source can be automatically cut off when remote alarm can be provided and meet high water level flood when possessing flood control height adjustable, chance low water level flood to make outdoor cabinet, thus try to gain time precious to one for cutting off whole incoming power, ensure the life security of the people.
As shown in Figure 1, 2, the main idea of the method is on the basis of existing outdoor cabinet 1, the high-order level sensor WS2 setting up low level water level sensor WS1 and be located thereon, whether low level water level sensor WS1 has water enter and send warning message in advance for detecting in outdoor cabinet 1, and whether high-order level sensor WS2 has soaked for the appliance circuit detected in outdoor cabinet 1, and carried out the keying of coordinated signals main breaker S1 by special mechanical part.
Be below the concrete steps for realizing this raising flood-control electric safety level of outdoor cabinet method:
1. first set up with lower device on existing outdoor cabinet 1, the position, middle and lower part of cabinet 1 fixedly mounts a vertical guide rail 2 out of doors, and the height of this guide rail 2 is about 1/3 ~ 2/3 of outdoor cabinet 1 cabinet height; The high-order level sensor WS2 installing low level water level sensor WS1 more afterwards on guide rail 2 and be located thereon; Because guide rail 2 adopts the vertical mode arranged, therefore two level sensors can be free to slide to regulate height residing separately on guide rail 2, when reality uses, user can according to actual conditions design flood control height such as this area's physical features, the water inlet alarm height namely residing for low level water level sensor WS1 and the dump height residing for high-order level sensor WS2 (flood control height);
It should be noted that, low level water level sensor WS1 and high-order level sensor WS2 all adopts mechanical float ball level sensor, for low level water level sensor WS1, when the ball float on it is in non-Riddled Condition, the ball float gravitate of rod member one end is sagging, and therefore contact a, b of the rod member other end often open, and when the ball float on it is in Riddled Condition, the ball float of rod member one end rises by buoyancy, and therefore contact a, b of the rod member other end are closed;
2. out of doors a monitor supervision platform is set in cabinet 1, it is made to be connected with low level water level sensor WS1, whether monitor supervision platform intakes for detecting interior of equipment cabinet, when low level water level sensor WS1 is in Riddled Condition, sent a warning message to user in advance by monitor supervision platform, remind related personnel to note, the mode of alarm can adopt and send the form such as alarm message, warning buzzing;
