Accompanying drawing explanation
Fig. 1 is the functional schematic that in the embodiment of the present invention, delayed releasing controls module.
Fig. 2 is the layout of intellectual electric leakage measurement monitoring protector in the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with Fig. 1 and Fig. 2, technical scheme is described further, but is not limited to this explanation.
A kind of intellectual electric leakage measurement monitoring protector, including housing, is provided with protective relay, transformer, display screen, charactron indicating lamp module, ZCT, CPU processor and protective relay in housing；Transformer and ZCT gather electric current and leakage current respectively, and transmit signals to CPU processor, and CPU processor transmits signals to protective relay, protective relay control contactor；Housing is provided with input keyboard, and input keyboard connects CPU processor, and input keyboard is for the needs according to corresponding home-use electricity, the warning value of input amount electric current, amount voltage, leakage current etc.；Display screen connects CPU processor, for receiving the signal of input keyboard input, and shows on a display screen by the signal that CPU processor feeds back, including failure code, real-time system voltage, real-time current value and real-time electrical leakage etc..
Charactron indicating lamp module includes alternator indicator, voltage indicator lamp, electric leakage display lamp and run indicator, and these display lamps light when circuit occurs abnormal, points out user.Arranging of every numerical value is relatively complicated; depend merely on input keyboard operation cumbersome; the CPU processor of the present invention is connected to WIFI module; user's APP software by downloading on mobile terminal such as mobile phone and the present invention is suitable; and utilize router to connect the present invention and this APP software, and the numerical value such as amount electric current, amount voltage, leakage current can be directly set on mobile phone, and the state of real-time monitoring and protecting device can be realized; for domestic consumer, be set or control all especially convenient.
User is by input keyboard or mobile terminal operation, input sets load current value, control module sets corresponding delayed releasing program at delayed releasing again, delayed releasing program can include multiple overload situations and multiple gear, such as: when in circuit, actual current is 1.2 times of rated current, alternator indicator Chang Liang, the delayed releasing time is 10 seconds, namely trips after 10 seconds；When in circuit, actual current is 1.5 times of rated current, alternator indicator Chang Liang, the delayed releasing time is 2 seconds, namely trips after 2 seconds；When in circuit, actual current is 3 times even higher of rated current, alternator indicator Chang Liang, instantaneous trip module can start effect moment, and protective relay starts, and disconnects catalyst, line disconnection electric current, plays a protective role.
Similar with electric current, the size of leakage current can count the startup index of delayed releasing equally, and the leakage current value and the time that set according to user realize delayed releasing function.Especially; when leakage current exceedes the 50% of the specified leakage current value of setting; alarm lamp is reported to the police; electric leakage display lamp flicker; when 1 times that leakage current exceedes the specified leakage current value of setting even higher, instantaneous trip module can start effect moment, and protective relay starts; making circuit disconnect, leak electricity display lamp Chang Liang.
The CPU processor of the present invention passes through the connection to input power and detection; also can realize electric voltage exception protection; such as overvoltage protection: when line voltage distribution is more than 232V; alarm lamp is reported to the police; voltage indicator lamp starts flicker, and when voltage is more than 253V, CPU processor controls protective relay and starts; circuit is made to disconnect, voltage indicator lamp Chang Liang；Low-voltage protection: when voltage is lower than 210V, alarm lamp is reported to the police, and voltage indicator lamp starts flicker, and when voltage is lower than 200V, CPU processor controls protective relay and starts, and makes circuit disconnect, voltage indicator lamp Chang Liang.
After electrical equipment is started working, CPU processor gathers electric current and leakage current by transformer and ZCT, and transmits a signal to display screen, real-time display system voltage, electric current and leakage current.When load is stepped up; electric current can be gradually increased, and when reaching the warning value preset, CPU processor outputs signal to charactron indicating lamp module; charactron indicating lamp module controls corresponding display lamp and makes the instruction of flicker or Chang Liang; delayed releasing controls program startup simultaneously, if electric current has been at excessive situation, reaches the setting time of delayed releasing; CPU can control separating brake and control output module; trigger protection relay, cuts off circuit, it is to avoid bigger accident occurs.If the electric current increased returns to normal size level within the delayed releasing setting time, electrical equipment is recovered to run well, then circuit maintains the original state.Housing is provided with separating brake, switch knob and testing button, when running into emergency and needing directly to control, can open or close circuit by separating brake, switch knob.This protector can set the time of delayed releasing according to actual needs, it is to avoid the unnecessary loss that frequently open circuit causes.
