Description
Technical field
The utility model is related to overcurrent protective switch technology.
Background technology
With the use of various high-power electric appliances, various switching devices and equipment are proposed with higher requirement, electrical equipment is set
Standby safety and its service life are increasingly paid attention to by people, but traditional insert row does not possess judgement and the guarantor of over-voltage and over-current
Protective function, electrical equipment high speed development and its an urgent demand to power safety are not caught up with far.When line voltage distribution is too high, electrical equipment overload or
When the phenomenons such as person's short circuit occur, gently then cause switching device, electrical equipment to damage, shorten the service life of electric equipment, it is heavy then
Generation electrical fire or explosion accident.
The content of the invention
The purpose of this utility model is, proposes a kind of Intelligent socket.
The utility model mainly includes over-current detection and protection part, alarm portion, voltage display portion.Over-current detection and
Protection part is made up of overcurrent relay and fuse.Alarm portion is made up of buzzer.Voltage display portion is by miniature number
Word voltmeter is constituted.
Intelligent socket of the present utility model, it is characterised in that：Mainly include live wire (1), zero line (2)；Live wire (1) connects successively
It is connected to fuse (3), button switch (4), overcurrent relay (6)；Minitype digital voltage is provided with button switch (4) output end
Table (5) is connected with zero line (2)；It is provided with and is connected by current-limiting resistance (8) with buzzer (7) in overcurrent relay (6) output end,
Buzzer (7) is parallel with indicator lamp (9)；When pressing SB, Minitype digital voltmeter (5) shows current voltage size, if circuit is short
When road or overcurrent value size are more than setting value, overcurrent relay (6) obtains electric, its normally opened auxiliary contact closure, indicates
Lamp is lighted, and buzzer (7) obtains electric send and blown a whistle, and normally closed auxiliary contact disconnects, and cuts off load loop.It is excessively electric when circuit is normal
Current relay (6) is discharged, and its normally opened auxiliary contact is separated, long to close auxiliary contact closure, and load loop is connected, and buzzer (7) breaks
Electricity stops blowing a whistle, and indicator lamp (9) extinguishes.Described overcurrent relay (6), is small-sized overcurrent relay, can be in loop
Automatic cutoff circuit when excessively stream or short circuit, protection is played a part of to electrical equipment.Described buzzer (7), can be in circuit excessively stream
When, send and blow a whistle.
This switching current loop is flowed into by live wire, and through fuse (3), button switch (4) connects voltage and indicates loop.Through electricity
Current relay coil connects load, and overload light and sound alarm circuit control its break-make by overcurrent relay normally open contact.
Outside function of the present invention with common insert row, a kind of insertion also with overcurrent protection and alarm and display voltage swing function
Row.
As a result of above-mentioned device, so the Intelligent socket has over-current detection and protection and alarmed, display voltage is big
Small function.So as to the safety of protection switch device and electric equipment, extend its service life, it is to avoid electrical fire or electrically
The generation of accident.
Compared with the prior art, the invention has the advantages that：
1st, with overcurrent detection, so as to avoid the generation of over-current and -load and short circuit phenomenon.
2nd, with function displaying voltage, people can be allowed intuitively to see the size of voltage.
3rd, with warning function, people can be allowed to know that electric equipment is now operated in abnormal or failure shape the very first time
Under state, and judge whether that needs are cut off the electricity supply, realize self-protection.
Brief description of the drawings
Fig. 1 --- for one of wiring schematic diagram
Fig. 2 --- it is the two of wiring schematic diagram
In figure：Live wire (1), zero line (2), fuse (3), button switch (4), Minitype digital voltmeter (5), overcurrent after
Electrical equipment (6), buzzer (7), current-limiting resistance (8), indicator lamp (9).
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, but the implementation of the present invention is not limited to this.
Reference picture 1, Fig. 2, the live wire (1) of Intelligent socket of the present utility model, zero line (2), fuse (3), button switch
(4), Minitype digital voltmeter (5), overcurrent relay (6), buzzer (7), current-limiting resistance (8), the parts such as indicator lamp (9)
And structure, acquisition can be manufactured or bought using prior art.Intelligent socket of the present utility model, can be carried out using prior art
It is completed.
Reference picture 1, Fig. 2, it is characterised in that：Mainly include live wire (1), zero line (2)；Live wire (1) is connected with fusing in turn
Device (3), button switch (4), overcurrent relay (6)；Button switch (4) output end provided with Minitype digital voltmeter (5) with
Zero line (2) is connected；It is provided with and is connected by current-limiting resistance (8) with buzzer (7) in overcurrent relay (6) output end, buzzer
(7) it is parallel with indicator lamp (9)；SB is pressed, digital voltmeter shows current voltage size, when line current is normal, line current
Value is less than setting value, and overcurrent relay is failure to actuate, and its normally-closed contact closure, circuit is connected.If circuit overload or short circuit exceed
When more than setting value, overcurrent relay action, its normally opened contact KA closures, indicator lamp lights, and buzzer, which is obtained, electric sends ring
Flute, normally-closed contact, which disconnects, cuts off load loop, realizes overcurrent protection.
In use, when pressing SB, Minitype digital voltmeter (5) shows current voltage size, if line short or excessively stream electricity
When flow valuve size is more than setting value, overcurrent relay (6) obtains electric, and its normally opened auxiliary contact closure, indicator lamp is lighted, buzzing
Device (7) obtains electric send and blown a whistle, and normally closed auxiliary contact disconnects, and cuts off load loop.When circuit is normal, overcurrent relay (6)
Release, its normally opened auxiliary contact is separated, long to close auxiliary contact closure, and load loop is connected, and buzzer (7) power-off stopping is blown a whistle,
Indicator lamp (9) extinguishes.Its overcurrent relay (6), is small-sized overcurrent relay, can be automatic in loop excessively stream or short circuit
Cutoff circuit, protection is played a part of to electrical equipment.Its buzzer (7), can send and blow a whistle in circuit excessively stream.
As a result of above-mentioned device, so the Intelligent socket has over-current detection and protection and alarmed, display voltage is big
