Abstract
The invention discloses a microcomputer intelligent arc light protective system, and relates to the technical field of electrical equipment. The microcomputer intelligent arc light protective system comprises a main control unit, arc light units, electric current units, breakers and a power source. The power source supplies power to the main control unit, then working voltage is supplied to the arc light unit and a circuit unit by the main control unit, the main control unit is respectively connected with the multiple arc light units, the multiple electric current units and the multiple breakers, and the arc light unit, the electric current units and the breakers are arranged in different switch cabinets. The microcomputer intelligent arc light protective system can monitor the situations of arc light and electric currents in the switch cabinets in real time and continuously transmit data detected to the main control unit, and the main control unit forecasts and judges faults likely to happen according to previous data and sends a trip operation signal to the breakers, so that damage to equipment is avoided.
Description
Technical field
The present invention relates to electrical equipment technical field, relate in particular to a kind of switch cubicle arclight protection system.
Background technology
Existing station-service/distribution Medium Voltage Switchgear is the power supply hinge of full factory subsidiary engine/electric power system; when internal fault takes place; whether can promptly excise fault; safe operation to full factory/distribution system is most important; but the middle pressure bus of present Medium Voltage Switchgear does not still dispose any special protection; but taken into account by the relevant backup protection of service entrance switch; and service entrance switch need cooperatively interact with the protection that goes out wiretap; and the differential 300ms that is at least of general fast tripping protection time-delay; even 500ms; and differential 1 – 2 seconds that reach especially of the cooperation of overcurrent protection; so; press any fault that takes place on the bus excision of all will delaying time at least in station-service/distribution system; in other words; the protection of pressing bus to excise fault in the very first time in the existing station-service also is blank; critical role in view of middle pressure bus; the time-delay excision of any fault; it all is our very be unwilling situation of seeing; because the various faults in the switch cubicle; the electric arc that its short circuit current produces and high temperature; the interior gas of cabinet is sharply expanded, can in the extremely short time, reach the peak, seriously jeopardize the person and device security.
Summary of the invention
The invention provides a kind of microcomputer-based intelligent arclight protection system; it can be real-time the monitoring switch cubicle in arc light and current conditions; and continue give main control unit with detected transfer of data; main control unit judges that according to data prediction in the past the fault of generation is sent the tripping operation actuating signal to circuit breaker possibly, thereby avoids the damage of equipment.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: comprise main control unit, arc light unit, current unit, circuit breaker, power supply, described power supply is powered to main control unit, offer arc light unit and circuit unit operating voltage by main control unit again, main control unit connects a plurality of arc lights unit, a plurality of current unit and a plurality of circuit breaker respectively, and arc light unit, current unit and circuit breaker are arranged in the different switch cubicles.
The present invention is with in current unit can be distributed to different switch cubicles with the arc light unit; detected arc light or current signal are sent to main control unit; main control unit is collected these data necessary its storage is calculated; export trip signal to circuit breaker according to actual conditions again; detected this switch cubicle electric current of current unit does not surpass set point if the luminous intensity that the arc light unit monitors surpasses set point; perhaps the detected electric current of current unit surpasses set point and luminous intensity that the arc light unit monitors surpasses set point; main control unit all can not exported trip signal to circuit breaker; when having only both detected signals all above set point; just can make the tripping operation action; the arc protection system disposition has an independently power supply in addition; when powering-off state appears in other system; system of the present invention still can operate as normal, thereby has guaranteed detection and protection to each switch cubicle.
The present invention it can be real-time the monitoring switch cubicle in arc light and current conditions, and continue give main control unit with detected transfer of data, main control unit judges that according to data prediction in the past the fault of generation is sent the tripping operation actuating signal to circuit breaker possibly, thereby avoids the damage of equipment.
