Description

Intelligent plastic casing break

Technical field

The utility model relates to a kind of intelligent plastic casing break.

Background technology

Intelligent plastic casing break is to be used to distribute electric energy, protection circuit, protection power-supply device in the distribution network, and the harm that prevents the fault such as overload, short circuit of power consumption equipment; The overload of existing mass-produced mold cased circuit breaker and short-circuit protection function are that the function by pyromagnetic structure realizes, be that overload protection is to make contact separately reach circuit by the action of bimetal leaf heated bending distortion pushing mechanism to disconnect the purpose that plays protection, short-circuit protection is to make the action of electromagnet armature action actuating mechanism make contact separately reach circuit by the big electric current of an electromagnet when the short circuit to disconnect the purpose that plays protection; This pyromagnetic architecture complexity, technology is complicated, and quality is wayward, and the properties of product instability makes the safe operation of electrical network and power consumption equipment can not get effective protection.

In addition, similar electronic type molded case circuit breaker is also arranged at present on the market, because its unreasonable, the software design defectiveness of controller electronic circuitry design, make the electronic type molded case circuit breaker unstable properties, the operating characteristics coverage error is big, makes the product error often surpass the scope of national standard or IEC standard code.

Summary of the invention

The purpose of this utility model is to overcome the defective of prior art, and more accurate stable, the speed of a kind of control protection intelligent plastic casing break faster is provided.

For achieving the above object, the utility model adopts a kind of intelligent plastic casing break, comprise the three-phase input module, the signal amplification module, the charge power supply module, 16 MCU processors, the parameter tuning module, fault output module and RS485 communication module, wherein said three-phase input module is wherein leaded up to the signal amplification module and is inserted 16 MCU processors, 16 MCU processors are inserted by the charge power supply module of giving 16 MCU processor chargings in another road, described parameter tuning module directly inserts 16 MCU processors, the fault output module picks out from 16 MCU processors, described RS485 communication module and 16 two-way connections of MCU processor.

By above-mentioned improvement to prior art; since adopted 16 the MCU processor and with each module between be connected; make that arithmetic speed, the protection speed of the MCU processor with respect to 8 that use on the market are all faster; and owing to also be provided with the RS485 communication module on this intelligent plastic casing break; can effectively realize remote control, remote regulating, remote measurement, distant communication function, further realize intelligentized purpose.

Preferably, described three-phase input module adopts 12 samplings.Because the AD that uses in the market sampling all is the compute mode of 4-8 position generally, thereby when adopting 12 bit arithmetic modes, make that the control protection of circuit breaker is more accurate stable.
