Abstract
The invention provides an intelligent arc light protection system for a microcomputer and relates to the technical field of power equipment. The intelligent arc light protection system comprises a master control unit, arc light units, current units, circuit breakers and a power supply, wherein the power supply supplies electricity to the master control unit; the master control unit provides working voltage to the arc light units and the current units; the master control unit is connected with a plurality of arc light units, a plurality of current units and a plurality of circuit breakers respectively; and the arc light units, the current units and the circuit breakers are arranged in different switch cabinets. The arc light and current conditions in the switch cabinets can be monitored in real time; the detected data can be continuously transmitted to the master control unit; and the master control unit predicts and judges a fault which is likely to happen according to the previous data and sends out tripping action signals to the circuit breakers, so that the damage to equipment is avoided.
Description
Technical field
The present invention relates to electrical equipment technical field, particularly relate to a kind of switch cubicle monitoring system.
Background technology
nullThe power supply hinge of existing conventional/distribution Medium Voltage Switchgear Shi Quan factory subsidiary engine/electric power system，When there is internal fault，Whether can promptly excise fault，Safe operation to full factory/distribution system is most important，But the middle pressure bus of current Medium Voltage Switchgear is still configured without any special protection，But taken into account by the relevant back-up protection of service entrance switch，And the protection of service entrance switch and outlet switch needs to cooperate，And the differential at least 300ms of typically fast tripping protection time delay，Even 500ms，And the cooperation of overcurrent protection is worse especially up to 12 seconds，So，Station-service/distribution system is pressed any fault occurred on bus the most at least want time delay to excise，In other words，Pressing bus in existing station-service can be also a blank in the protection of very first time excision fault，Critical role in view of middle pressure bus，The time delay excision of any fault，It it is all our situation of being extremely unwilling to see，Because the various faults in switch cubicle，Electric arc and high temperature produced by its breaking current，In making cabinet, gas drastically expands，Peak can be arrived within the extremely short time，Seriously jeopardize the person and equipment safety.
Summary of the invention
The invention provides a kind of microcomputer intelligent arc light protective system; it can be real-time detection switch cubicle in arc light and current conditions; and keep the data detected are transferred to main control unit; according to conventional data prediction, main control unit judges that the fault occurred possibly sends trip operation signal to chopper, thus avoid the damage of equipment.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: include main control unit, arc light unit, current unit, chopper, power supply, described power supply is powered to main control unit, it is supplied to arc light unit and circuit unit running voltage again by main control unit, main control unit connects individual arc light unit, multiple current unit and multiple chopper respectively, and arc light unit, current unit and chopper are arranged in different switch cubicles.
nullThe present invention is arc light unit and current unit can be distributed in different switch cubicles，The arc light detected or current signal are sent to main control unit，Main control unit is collected the data of these necessity and is stored calculating，Trip signal is being exported to chopper according to practical situation，If the light intensity that arc light unit monitors exceedes setting value and this switch cubicle electric current that current unit detects is not less than setting value，Or the electric current that current unit detects exceedes setting value and light intensity that arc light unit monitors is not less than setting value，Main control unit all will not export trip signal to chopper，When the signal that only both detect is all beyond setting value，Just can make trip operation，Additionally arc light protecting system is equipped with an independent power supply，When other system outlet powering-off state，Present system still can normally work，Thus ensure that the protection of the detection to each switch.
The present invention it can be real-time the arc light of monitoring switch cabinet and current conditions, and lasting the data detected are transferred to main control unit, according to conventional data prediction, main control unit judges that the fault occurred possibly sends trip operation signal to chopper, thus avoid the damage set.
Accompanying drawing explanation
Fig. 1 is one embodiment of the invention schematic diagram.
Detailed description of the invention
Shown in Fig. 1; a kind of microcomputer intelligent arc light protective system; including main control unit, arc light unit, current unit, chopper, power supply; described power supply is powered to main control unit; it is supplied to arc light unit and circuit unit running voltage again by main control unit; main control unit connects individual arc light unit, multiple current unit and multiple chopper respectively, and arc light unit, current unit and chopper are arranged in different switch cubicles.
nullThe present invention is arc light unit and current unit can be distributed in different switch cubicles，The arc light detected or current signal are sent to main control unit，Main control unit is collected the data of these necessity and is stored calculating，Trip signal is being exported to chopper according to practical situation，If the light intensity that arc light unit monitors exceedes setting value and this switch cubicle electric current that current unit detects is not less than setting value，Or the electric current that current unit detects exceedes setting value and light intensity that arc light unit monitors is not less than setting value，Main control unit all will not export trip signal to chopper，When the signal that only both detect is all beyond setting value，Just can make trip operation，Additionally arc light protecting system is equipped with an independent power supply，When other system outlet powering-off state，Present system still can normally work，Thus ensure that the protection of the detection to each switch.
The present invention it can be real-time the arc light of monitoring switch cabinet and current conditions, and lasting the data detected are transferred to main control unit, according to conventional data prediction, main control unit judges that the fault occurred possibly sends trip operation signal to chopper, thus avoid the damage set.
