Description
Technical field
The present invention relates to intelligent electric appliance technical field, more particularly to a kind of IP-based miniature circuit breaker.
Background technology
Miniature circuit breaker, abbreviation MCB（Micro Circuit Breaker ）, it is that architectural electricity terminal power distribution draws
In a kind of most popular terminal protection electrical equipment.Single-phase, three-phase short circuit, overload, overvoltage for below 125A etc. are protected,
Including monopole 1P, four kinds of two pole 2P, three pole 3P, quadrupole 4P etc..Nowadays, the miniature circuit breaker that we commonly use, it is impossible to realize certainly
Dynamic circuit connector lock and remote switching.We cannot learn family's physical circuit situation, and can not carry out remote control.Therefore, we
Need a kind of IP-based miniature circuit breaker.Remotely it can be monitored and controlled.Because the technical scheme of the patent is base
Solved in the mode of IP, but it is some leading scenes, range of application more narrow sense that can not adapt to by mechanical structure.
The content of the invention
It is an object of the invention to design a kind of IP-based miniature circuit breaker.
To achieve the above object, the technical solution adopted by the present invention is as follows：A kind of IP-based miniature circuit breaker, including it is micro-
Type breaker and intelligent object.By three contact series in three-phase main circuit, after operation handle is closed, contact is protected by locking key
Hold in closure state, locking key is support by having contact with, and having contact with can be with pivoting.If have contact with to be opened by lever top, contact just by
Spring is pulled open, circuit disjunction., when circuit is short-circuited, there is very big overcurrent in coil and the main circuit series connection of magnetictrip
When, the electromagnetic attraction that the ironcore choke of current release is produced could be by armature adhesive.Lever is clashed into during armature adhesive, has contact with top
Up, open contact.When circuit overloads, overload current flows through resistive heater and bimetal leaf is generated heat and bend,
Can will equally have contact with top to open, make contact disjunction, play overload protective function.Described intelligent object is connected in the line, receives letter
Number the electromagnetic switch is controlled, come remote separating brake, or to be realized by protective relaying device action automatically so as to using shunt release
Tripping operation.
Preferably, described intelligent object, is provided with Wi-Fi module.
Preferably, described intelligent object, is provided with Zigbee module.
Preferably, described intelligent object, is provided with RJ45 interfaces.
Preferably, when line current overloads, resistance heating excess causes bimetal leaf to be received to described overcurrent trip
Heat is bent upwards, and promotes push rod upwards, and top is opened and had contact with, chief commander's circuitry cuts.Control device is sent to by intelligent object simultaneously
（Mobile phone, computer）.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is intelligent object structure chart of the invention；
1 is contact in figure, and 2 is locking key, and 3 to have contact with, and 4 is axle, and 5 to clash into lever, and 6 is spring, and 7 is overcurrent trip, and 8 are
Under-voltage release, 9 is armature, and 10 is armature, and 11 is spring, and 12 is bimetal leaf, and 13 is resistive heater, and 14 is de- for shunt opening
Button device, 15 is electromagnetic switch, and 16 is making electromagnet, and 17 is intelligent object, and 18 is central processing module, and 19 is internal memory, and 20 are

Specific embodiment
Its contact 1, has three, is connected in three-phase main circuit, and after operation handle is closed, contact 1 is protected by locking key 2
Hold in closure state, locking key 2 is support by having contact with, and having contact with 3 can rotate around axle 4.If having contact with 3 to be opened by the top of lever 5, contact
1 is just pulled open by spring 6, circuit disjunction.Intelligence 17 is connected with the coil and main circuit of magnetictrip, when circuit is short-circuited,
When very big overcurrent occurs in the detection of intelligent object 17, the electromagnetic attraction that the ironcore choke of overcurrent trip is produced could be by armature
9 adhesives（Suction produced by normal current can not make armature movement）.Lever 5 is clashed into during 9 adhesive of armature, having contact with 3 tops up,
Open contact 1.On the main circuit, when line voltage distribution is normal, under-voltage release is produced the coils from parallel connection of coils of under-voltage release 8
Raw suction can be by its adhesive of armature 10, if line voltage distribution drops to certain certain value, the suction of under-voltage release subtracts
Small, armature 10 is pulled open by spring 11, at this moment same to clash into lever 5, is opened 3 tops are had contact with, it is also possible to open contact 1.Heat is threaded off
The effect of device is identical with electrothermal relay, and when circuit overloads, overload current flows through resistive heater 13 and makes bimetal leaf
12 heating bendings, can will equally have contact with 3 tops and open, and make contact disjunction, play overload protective function.Described intelligent object 17 is connected on electricity
Lu Zhong, receive signal control electromagnetic switch 15 so as to using shunt release 14 come remote separating brake, or by relay protection dress
Action is put to realize automatic trip.In described intelligent object, it is provided with RJ45 interfaces 22 and is connected with central control module 19, it is another
