Abstract
The utility model provides a microcomputer intelligent harmonic elimination device, relating to the technical field of circuit protection devices. The device comprises an acquisition module which collects signals by a system voltage transformer and transmits the signals to a CPU master control unit. The CPU mater control unit processes the signals and transmits the signals to a harmonic elimination module. The harmonic elimination module performs harmonic elimination on the system voltage by the system voltage transformer. The device is characterized in that the CPU master control unit is also connected with a display module, and the CPU master control unit is an M3 core 32-bit processor. The microcomputer intelligent harmonic elimination device provided by the utility model has the advantages of high intelligence, convenient operation, simple control and good protection effects.
Description
Technical field:
The utility model relates to circuit protection device technical field, specifically microcomputer-based intelligent harmonic elimination apparatus.
Background technology:
Resonance eliminator is the damping device of protection voltage transformer primary side, the resonance being used in harmonic elimination electrical network.Power supply system overvoltage phenomenon is very general, if there is no the precautionary measures, all may occur at any time to blow out such as cable.These type of accidents such as electrical machine insulation punctures, PT burns, overvoltage causes direct destruction to the electric elements in electric or electronic installation.Resonance eliminator is in the market mainly LXQ series (also having part producer is RXQ).Resonance eliminator LXQ as a kind of new model.L represents exposed, and XQ represents harmonic elimination.It is little that exposed resonance eliminator has volume, is particluarly suitable for installing in switch cubicle.But the resonance eliminator on market is not intelligent, controlling and use inconvenience, can not well play the effect of protection.
Utility model content:
Technical problem to be solved in the utility model is to provide a kind of user's control operation convenient, succinct, protects effective microcomputer-based intelligent harmonic elimination apparatus.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
Microcomputer-based intelligent harmonic elimination apparatus, comprise acquisition module, acquisition module is passed to CPU main control unit by system voltage instrument transformer collection signal and by signal, described CPU main control unit is passed to harmonic elimination module after signal is processed, harmonic elimination module is carried out harmonic elimination by system voltage instrument transformer to system voltage again, it is characterized in that: on described CPU main control unit, be also connected with display module, CPU main control unit is M3 core 32 bit processors.
Described device also comprises key-press module, and key-press module is connected with CPU main control unit.
Described device also comprises system alarm and control and I/O unit, and described system alarm is connected with CPU main control unit by I/O unit.
Described device also comprises host computer and communication module, and described host computer is connected with CPU main control unit by communication module.
Described device also comprises host computer and communication module, and described host computer is connected with CPU main control unit by communication module.
Described display module is TFT2.8 cun of liquid crystal display.
The present invention adopts M3 core 32 bit processors to three-phase and residual voltage sampling, by calculating voltage effective value, by frequency real-time tracking, comes judgement system in which kind of state.Display module sampling voltage show, display system once with secondary line voltage and phase voltage.Adopt private memory to the fault storage that circulate, store number of times and can be greater than as required record 88 times.Can adopt controllable silicon to process system generation resonance.RS485 communication mode, RS485 communication and isolation of system, can avoid the impact of external circuit on native system, and support MODBUS agreement, can communicate with the equipment of any this agreement of support.
Preferably adopt TFT2.8 cun of liquid crystal display, can be very vivid demonstrate system mode, graphic interface shows, allows user's more convenient operation, more succinct.Adopt 32 treatment technologies of M3 core, changeable frequency is followed the trail of, and can eliminate 10 ~ 300HZ optional frequency; Than eliminating in the past fixing several frequencies, install more advanced, more practical.
The beneficial effects of the utility model are: the intelligent degree of the utility model is high, and more convenient operation is controlled simply, protects effective.
Accompanying drawing explanation:
Fig. 1 is the utility model module diagram.
