As long as not powering off in system, arc light will be always existed.To reduce the harm of arc light to greatest extent, it would be desirable to Yi Zhongan
Entirely, efficient semiconductor arc light protective device rapidly.
In switch cabinet drawer, it is remote that arc light can rapidly reach 3M in 10ms, therefore to utmostly reduce damage
It loses, the time is a most important factor.Arc light protective device export the trip signal time less than 1 ms, even if installation or
Also the safety of operator can be protected when maintenance.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of arc light protecting device, the application one
A main control unit can protect several independent switchgears simultaneously, therefore, the arc light unit and current unit of arc light protective device
It can be distributed in different switchgears, the arc light or current signal that detect are transmitted to main control unit, main control unit is collected
To these necessary data, trip signal is exported according to the actual situation to breaker, is communicated by optical fiber, reaction speed is fast,
Movement is accurate, high degree of automation.
The purpose of this utility model is achieved through the following technical solutions:
A kind of arc light protecting device, including main control unit, and the arc light unit and electric current that are distributed in several switchgears
Unit；The signal end of arc light unit and current unit is connected by data line and optical fiber with the signal end of main control unit, main
The control signal output of control unit is also connected with the control signal of breaker；Arc light unit includes electric arc protection main mould
Block, electric arc protection supplementary module and arc photosensor, arc photosensor are set in switchgear；Electric arc protection supplementary module packet
Electric power management circuit and data transfer circuit are included, and electric arc protection main module is used to that the electric arc light data of acquisition to be carried out at data
Reason；Current unit includes current monitoring circuit and overcurrent-overvoltage observation circuit.
Preferably, main control unit includes that 4 quick independent trips, 1 independent alarm bus and 6 conventional relays go out
Mouthful.
The beneficial effects of the utility model are: one main control unit of the utility model can protect several independent switches simultaneously
Cabinet, therefore, the arc light unit and current unit of arc light protective device can be distributed in different switchgears, what is detected
Arc light or current signal are transmitted to main control unit, and main control unit is collected into these necessary data, and output is jumped according to the actual situation
Lock signal is communicated to breaker by optical fiber, and reaction speed is fast, and movement is accurate, high degree of automation.
Detailed description of the invention
Fig. 1 is the circuit structure connection block diagram of the utility model；
Fig. 2 is the utility model method flow schematic diagram；
In figure, 101- main control unit, 102- arc photosensor, 103- electric arc protection main module, 104- current monitoring electricity
Road, 105- overcurrent-overvoltage observation circuit, 106- electric power management circuit, 107- data transfer circuit, 108- breaker.
Specific embodiment
The technical solution of the utility model, but the protection scope of the utility model are described in further detail with reference to the accompanying drawing
It is not limited to as described below.
A kind of arc light protecting device please refers to shown in attached drawing 1, including main control unit 101, and is distributed in several switchgears
Interior arc light unit and current unit；The signal end of arc light unit and current unit passes through data line and optical fiber and master control list
The signal end of member 101 is connected, and the control signal output of main control unit 101 is also connected with the control signal of breaker 108；Arc
Light unit includes electric arc protection main module 103, electric arc protection supplementary module and arc photosensor 102, arc photosensor 102
In switchgear；Electric arc protection supplementary module includes electric power management circuit 106 and data transfer circuit 107；Current unit
Including current monitoring circuit 104 and overcurrent-overvoltage observation circuit 105.
Preferably, main control unit 101 includes 4 quick independent trips, 1 independent alarm bus and 6 conventional relays
Outlet.
It should be noted that electric arc protection main actions are according to two different factors for being failure generation: arc light and electricity
Flow increment.Trip signal is issued when being detected simultaneously by arc light and current increment.Electric arc protection consists of three parts: arclight
Protect main module 103, electric arc protection auxiliary unit and arc photosensor 102.Arc photosensor 102 can be placed in switchgear
Any position, the function of protection subregion can be realized according to the actual physical location of arc photosensor 102, and in electric arc protection
The position that failure occurs is shown on main module 103, this function can reduce the processing time of power-off, and becoming fast recovery of power supply can
Energy.
Data transmission of the utility model between main control unit 101 and arc light unit or current unit is by optical fiber and data
Transmission line is completed.Optical fiber transmits trigger signal to main control unit.Working power, alarm signal, automatic control data message stream
Transmission is then completed by data line.Main control unit provides 4 quick 1ms independent trips and alarm bus and 6 routines
Relay outlet.
When being attached in system, it is necessary to carefully consider the position of the switch of each the last one current unit of bus.It opens
Off position determines that can this current unit be worked normally by the program of setting.
Specific embodiment of the present utility model above described embodiment only expresses, the description thereof is more specific and detailed,
But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field
