It is sent to described central processing unit, by described central processing unit computing output and carried out numerical value by described display module and show.
Customer parameter utilizes software editing good through pc client, is issued to described central authorities by communication serial ports or wireless network
In processor (customer parameter includes rated power, overload power, permission overload time etc.), when customer charge is normal, from institute
The customer parameter stating the signal storage interior with described central processing unit that the sampling of phase current sample coil comes is made comparisons, if detection ginseng
Number is less than the rated power of customer parameter, then equipment runs well；If it exceeds the rated power of customer parameter, but it is less than
Overload power, the most described central processing unit starts timing, when load exceedes rated power but is not above the permission overload set
Time i.e. recovers normal, then overload time next time is from zero meter；When based model for load duration exceedes rated power and exceedes the permission of setting
After the load time, the most described central processing unit sends trip command, by described leakage protection module and described circuit breaker tripping line
Circle carries out safety trip.
When customer charge directly exceedes overload power, and the most described central processing unit directly sends trip command.Described central authorities
Processor sends trip command and connects described zero line leakage tests branch road by described leakage protection module, makes zero-sequence current sample
Coil midstream crosses out-of-balance current, so that described leakage protection module judges that system exists electric leakage and sends trip command, and control
Make described circuit breaker tripping coil to connect, make tripping mechanism tripping operation thus disconnect user's power supply.
The described central processing unit of the present embodiment passes through three described phase current sample coil detection load, judges user
Power load size, when user power utilization load exceedes assumed load value and during not less than maximum, and described central processing unit starts
Timing, when based model for load duration is constant, timing time reaches setting value and trips, when customer charge exceedes maximum, by described
Central processing unit directly sends trip command, controls customer charge with this.
The present embodiment mainly realizes following functions:
One, short-circuit protection.When there is overload, are short-circuited in protected circuit or subscriber equipment, phase current sample coil
In flow through larger current, drive circuit breaker tripping coil to complete instantaneous trip action, thus cut off the electricity supply and play overload or short circuit
Protective effect.
Two, earth leakage protective.When having in by protection circuit phase line grounding or the person to get an electric shock, as long as residual current reaches to adjust
Working value, zero-sequence current sample coil just one signal of output, under the control of described leakage protection module, drive chopper to take off
Fastening wire circle completes instantaneous trip action, starts electric leakage and electrical shock protection effect.
After above-mentioned technological improvement, the present embodiment can bring following benefit:
One, power supplying efficiency is improved.The effectively containment platform district uncontrolled growth of load, reduces the damage that circuit increases because of overload
Consumption, reduces transformator heavy duty, the generation of overload situations, improves the controllability of load and orderly development, alleviate power supply enterprise with
Electric power distribution transforming increase-volume pressure during electricity peak.
Two, power supply cost is saved.All of electric cost, finally can embody by the way of finance are settled accounts with cash
Out, the expense not causing other rises and increases extra work amount.As caused transformator because of user's unordered increase load
The demand of capacity strengthens, and the investment of increase-volume and labour cost；Transformator heavy duty, overload is caused because of user's unordered increase load
The line loss loss brought increases, degradation loss under quality of voltage；Because user's unordered increase load causes transformator overload to burn out
Replacing and labour cost etc..
Three, power supply quality is improved.There is provided stable electric power for electrical equipment, effectively control line losses indices, improve platform district electricity
Pressure quality.
Four, arrearage trip avoidance function.The expense control function newly increased, coordinates with described marketing mis system and gauge table, can realize
Arrearage trip remotely function, thus it is prevented effectively from the risk of big power family owing electricity charges, save manpower output.
After the present embodiment is by above-mentioned technological means, power user is regardless of whether connect and use zero line, and central processing unit can
The voltage utilizing 380V normally works so that user cannot walk around the detection of central processing unit, so that customer charge begins
Eventually all in monitoring, it is to avoid promise breaking electricity consumption, the containment Liao Tai district uncontrolled growth of load, reduces line losses indices, carries effectively
Gao Liaotai district quality of voltage, in addition, also add power consumption control function, i.e. takes control function, utilize the tripping operation of chopper
Mechanism coordinates with marketing system and gauge table, can realize arrearage trip remotely function, can be effectively prevented from big power family and be in arrears with electricity
The risk taken, it is to avoid the uncertain factor urging expense and produce of manually visiting, reduces artificial output, is effectively prevented from urging expense process
In the generation of the phenomenon such as the complaint that causes with user's confusing communication.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.The technology of the industry
Personnel, it should be appreciated that the present invention is not restricted to the described embodiments, simply illustrating this described in above-described embodiment and description
The principle of invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these become
Change and improvement both falls within scope of the claimed invention.Claimed scope by appending claims and
Equivalent defines.
