Abstract
The utility model discloses a kind of user side Intelligent operation control device of switch cabinet.The user side Intelligent operation control device of switch cabinet adopted, it is characterized in that: comprise CPU, switching input module, voltage sample module, current sample module, described switching input module is connected with CPU by optical coupling isolation circuit, and described voltage sample module, current sample module are connected with CPU by electricity isolation transformer.User side Intelligent operation control device of switch cabinet of the present utility model, what when high-tension switch cabinet runs, bus passed through is kilo-ampere level and above operating current, the magnetic interference produced is stronger, especially during vacuum circuit-breaker deciliter electric current, to capacitive or perceptual small area analysis, the electromagnetic interference that the reasons such as the sudden change recovery voltage due to circuit is high produce is very strong.
Description
Technical field
The utility model relates to a kind of Intelligent operation control device of switch cabinet.
Background technology
Along with developing rapidly of the overall power distribution automations such as industrial and mining enterprises, power plant, transformer station, the intellectuality of switchgear becomes inexorable trend, the high-tension switch cabinet playing the important function such as control and protection in distribution network stands in the breach, its utilization is at the scene very extensive, but in practice, have following problem and potential safety hazard: although 1. every face switch cubicle all once winding diagram, can not each parts real-time running state of Dynamic Announce switch cubicle; Although 2. switch cubicle has machinery " anti-error ", but if add that voice anti-fault prompting then can facilitate alert proper operation order; 3. current old switch cubicle still uses neon lamp as switch cabinet electrified display device in a large number, but neon lamp is through long-play, and blindness is high, poor reliability; 4. low temperature, high humidity all can cause switch cubicle decreasing insulating, need to carry out Temperature and Humidity Control in switch cubicle; 5. long-range/on the spot, the manipulation of switches position such as divide-shut brake puts irregular, wiring is in disorder and inconvenient; 6. without RS485 communication function, be not easy to realize " remote control ", " remote signalling ", " remote measurement ".
Utility model content
The technical problems to be solved in the utility model is to provide a kind of user side Intelligent operation control device of switch cabinet.
For solving the problem, the user side Intelligent operation control device of switch cabinet that the utility model adopts, it is characterized in that: comprise CPU, switching input module, voltage sample module, current sample module, described switching input module is connected with CPU by optical coupling isolation circuit, and described voltage sample module, current sample module are connected with CPU by electricity isolation transformer.
Described user side Intelligent operation control device of switch cabinet, is characterized in that: described CPU is also connected with humiture collection module, figure indicating circuit, LCD liquid crystal display circuit, switching value output module, a RS485 telecommunication circuit.
User side Intelligent operation control device of switch cabinet of the present utility model, what when high-tension switch cabinet runs, bus passed through is kilo-ampere level and above operating current, the magnetic interference produced is stronger, especially during vacuum circuit-breaker deciliter electric current, to capacitive or perceptual small area analysis, the electromagnetic interference that the reasons such as the sudden change recovery voltage due to circuit is high produce is very strong.Also Lightning Over-voltage etc. is there is in addition in circuit.In order to ensure the normal work of Intelligent control device, system fully have employed following EMC Design: power supply Anti-interference Design, power supply input adopts high frequency filter to carry out filtering from the circuit breaker deciliter high frequency spike produced, and adds electricity isolation transformer in addition during design; Isolation design: RS485 interface, On-off signal and relay export and all have employed light-coupled isolation, isolate each other, electric current, voltage measurement have employed electricity isolation transformer between the power supply of each road not altogether, achieve the isolation between input/output signal; Grounding design: digital and analog circuit single-point grounding during design; Reasonable line arrangement: power supply and signal section separate by reasonable layout element: analog-and digital-part is separated, and reasonably connect up: reduce via hole, intersection etc. as far as possible.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is circuit theory diagrams of the present utility model.
