Digital intelligent integral type control protective unit

Technical field

The utility model relates to a kind of control protective unit, particularly a kind of digital intelligent integral type control protective unit.

Background technology

At present, low voltage control protective device, mainly motor monitored and protect, the multiple situations such as the overload occurred in motor operation course, phase shortage, imbalance, underload, electric leakage, external fault are protected, and can need to control according to the scene such as fire-fighting, building; Existing control protective unit usually adopt discrete component as: signal lamp, button, electric bell, auxiliary reclay, the time relay, control transformer, universal seclector, wire etc. are assembled; There is the deficiency that components and parts are many, secondary distribution is loaded down with trivial details, failure rate is high, because distribution adopts AC220/AC380V voltage, in humidity and hot environment, the fault of line short also easily occurs.

Utility model content

In order to solve the deficiency of above-mentioned existing control protective unit, the utility model provides a kind of digital intelligent integral type control protective unit.

The utility model solves the technical scheme that its technical matters adopts: digital intelligent integral type control protective unit, comprise CPS Control protection switch, also comprise the monolithic microcontrol processor for signal control treatment, the AC/DC power transfer module for Power convert, for digital signal store eeprom memory module, for exchanges data RS232 data exchange module, for receive external signal input input signal module, for show and controls LED display and key control module, for control signal output output signal module; Described monolithic microcontrol processor connects CPS Control protection switch, AC/DC power transfer module, eeprom memory module, RS232 data exchange module, input signal module, LED display and key control module, output signal module respectively.

The external input signal that described input signal module receives comprises: run signal, on the spot button signal, short-circuit signal, overload signal, fire-fighting signal, building signal, fire resisting damper signal, emergency parachute.

The output signal of described output signal module comprises: manual/auto return signal, operation return signal, the return signal that stops, auxiliary return signal, overload return signal, short circuit return signal.

Described AC/DC power transfer module be input as AC220V, export as DC12V or DC5V.

The beneficial effect that the utility model has is: adopt Digital Circuit Control mode to instead of traditional mechanical analogue control mode, adopt integrated circuit, electronics pcb board technique, SMT automatic pasting technique technology, moistureproof, high temperature resistant, greatly reduce traditional secondary line trouble spot, reliability is high simultaneously; Easy to assembly, debugging is simple, reduces cost of labor, and complete casing reduces, and greatly reduces material cost; Except CPS Control protection output switching terminal mouth is except AC220V, other all of the port outlets are below low pressure 36V or passive signal, installation personnel to field wiring, debug fast safer.
