Technical field
It the utility model is related to a kind of electric product field, more particularly to a kind of intelligent capacitor.
Background technology
With the development of economy and society, electricity needs also sustainable growth, higher requirement is there has also been for the quality of power supply.With
It is made up of toward reactive power compensator multiple electric products such as intelligent controller, fuse, combination switch, electrothermal relay, capacitor, and
Intelligent capacitor such as integrates modern test and control, power electronics, communicates, automatically controls at the advanced technology, changes traditional reactive-load compensation dress
Backward control technology is put, changes the huge volume of traditional reactive power compensator and bulky structure, intelligent capacitor module
Change structure and make it that compensation effect is more preferable, volume is smaller, and power consumption is lower, easy to use, adapts to requirement of the power network to reactive-load compensation.But
It is that existing intelligent capacitor communication mode is single, flexibility is lacked in communication aspects, it is impossible to meets and different object communications
Demand, it is therefore desirable to it is a kind of solve intelligent capacitor communication unicity problem technical scheme.
The content of the invention
In view of this, the purpose of this utility model is to provide that one kind can meet different communication demand and communication mode has
Flexibility, multifarious intelligent capacitor.
In order to realize the above object the utility model uses such a intelligent capacitor, including processor, power supply, letter
Number collection isolation module, key-press module, liquid crystal display, relay drive circuit, relay, RS485 modules, CAN module, the letter
Number collection isolation module gathers three-phase voltage, isolate after be input to processor, the output end of key-press module connects processor
Input, the output end of processor connect the input of liquid crystal display and relay drive circuit respectively, relay drive circuit
Output end connects the input of relay, and power supply is powered after three-phase voltage step-down rectifier for whole intelligent capacitor, described
The side of RS485 modules and CAN module connects the communication ends of processor respectively.
Above-mentioned intelligent capacitor realizes the transmission of electric power data by RS485 modules and CAN module, but RS485 modules are led to
Letter is different with the object of CAN module communication, and wherein CAN module forms constructing communication network, can realize quick between main frame and slave
Communication, and RS485 modules communicate with upper computer software, realization communicates with distribution terminal, and communication modes are more various, meets different logical
The demand of letter.
This practicality, which is further arranged to intelligent capacitor, also includes RJ45 interfaces and external current transformer, the RS485
The opposite side of module and CAN module connects RJ45 interfaces, the output end connection RJ45 interfaces of the external current transformer respectively.
Above-mentioned RS485 modules and CAN module are connected to RJ45 interfaces, and external current transformer connects the current signal of sampling
RJ45 interfaces are connected to, have unified the wiring direction of communication, current signal is connected to external capacitor by RJ45 interfaces, simultaneously
RJ45 interfaces have the function of preventing from loosening, being formed self-locking, improve the stability of communication.
This practicality is further arranged to the model M453RD3AE of processor.
Above-mentioned processor M453RD3AE can realize to communicate with CAN, RS485, and low-power consumption, performance is high, price is low.
Brief description of the drawings
Fig. 1 is the utility model embodiment functional-block diagram.
Embodiment
As shown in figure 1, the utility model is a kind of intelligent capacitor, including processor, power supply, signal acquisition isolation mode
Block, key-press module, liquid crystal display, relay drive circuit, relay, RS485 modules, CAN module, RJ45 interfaces and external electric current
Transformer, the model M453RD3AE of the processor, the signal acquisition isolation module gathers three-phase voltage, isolate after
Processor, the input of the output end connection processor of key-press module are input to, the output end of processor connects liquid crystal display respectively
With the input of relay drive circuit, the input of the output end connection relay of relay drive circuit, power supply is by three-phase
After voltage step-down rectification, powered for whole intelligent capacitor, connection is handled respectively for the side of the RS485 modules and CAN module
The opposite side of the communication ends of device, RS485 modules and CAN module connects RJ45 interfaces respectively, the external current transformer it is defeated
Go out end connection RJ45 interfaces.
According to above example, the signal sampling isolation module of intelligent capacitor is adopted the voltage signal of three-phase and four-line
Sample, isolation, obtained sampled signal are input to processor, and external current transformer is sampled current signal, processor root
To give relay drive circuit signal, driving relay work according to sampled signal, wherein CAN module forms constructing communication network, can be real
Existing high-speed traffic between main frame and slave, RS485 modules communicate with upper computer software, and realization communicates with distribution terminal, meet
The demand of different communication.
