Multifunctional intelligent power distribution box

Abstract

The invention discloses a multifunctional intelligent power distribution box which comprises a 380V power distribution box, a 220V power distribution box and a firefighter tank, wherein the 380V powerdistribution box is internally provided with a main circuit breaker, 380V leakage protectors and 380V intelligent relays; the 220V power distribution box is internally provided with 220V leakage protectors; the firefighter tank is internally provided with a smoke sensitive alarm and a dry powder fire extinguisher; input ends of the plurality of 380V leakage protectors and the plurality of 220V leakage protectors are all connected with the main circuit breaker; input ends of the plurality of 380V intelligent relays are connected with output ends of the plurality of 380V leakage protectors in aone to one correspondence manner; output ends of the plurality of 380V intelligent relays are connected with power supply input ends of a plurality of 380V working sockets in a one to one correspondence manner; output ends of the plurality of 220V leakage protectors are connected with power supply input ends of a plurality of 220V WiFi intelligent sockets in a one to one correspondence manner; the 380V intelligent relays and the plurality of 220V WiFi intelligent sockets are connected with a controller. By adopting the multifunctional intelligent power distribution box, power supply of large-size equipment and small-size equipment can be achieved, and, remote intelligent control can be achieved.

Description

technical field [0001] The invention relates to the field of power distribution equipment, in particular to a multifunctional intelligent power distribution box. Background technique [0002] A lot of electrical equipment is often used in the construction of civil engineering. Due to the simultaneous use of large equipment and small equipment, and the simultaneous use of power and lighting electricity, there are many electrical equipment on site, random connections and pulls occur, and switches are frequently used, resulting in The secondary and tertiary power distribution boxes are chaotic, and the temporary power consumption during construction has become a major source of danger on the construction site. At the same time, short-circuit, leakage, and electric shock accidents are prone to occur. [0003] At present, the requirements for temporary power consumption (JGJ46-2005) at traditional construction sites are: [0004] (1) In the TN-S zero-connection protection system...

AI Technical Summary

Problems solved by technology

[0006] (3), each electrical equipment must have its own dedicated switch box, and it is strictly forbidden to use the same switch box to directly control 2 or more electrical equipment (including sockets)

[0007] (4) The electrical installation board of the distribution box must be equipped with N line terminal board and PE line terminal board

[0010] Disadvantages of this kind of distribution box: 1. During configuration, too many electrical appliances often lead to insufficient shunting of the secondary distribution box, and multiple secondary distribution boxes have to be configured, resulting in over-shunting of the main distribution cabinet. If there are too many, increase the cables between the main distribution box and the distribution box; 2. When in use, due to too many electrical appliances, the number of switch boxes cannot meet the needs, resulting in a gate with multiple functions, and the wires are randomly connected; 3. When in use, Due to the fire-fighting requirements, the working surface requires fire-fighting equipment, and the site has to be equipped with a separate fire-extinguisher box
