Abstract
The present invention discloses an intelligent electric arc light protection system with a microcomputer, which relates to the technical field of electrical equipment. The system comprises a master control unit, arc light units, current units, circuit breakers and a power source, wherein power is supplied to the master control unit by the power source, then operating voltage is supplied to the arc light units and the current units by the master control unit, the master control unit is respectively connected to a plurality of arc light units, a plurality of current units and a plurality of circuit breakers, and the arc light units, the current units and the circuit breakers are arranged in different switch cabinets. The system disclosed by the present invention can monitor arc light and current in switch cabinets in real time and continuously transmit detected data to the master control unit, so that the master control unit predicts and judges a fault which will occur possibly according to previous data and sends tripping action signals to the circuit breakers, thereby avoiding damage to equipment.
Description
Technical field
The present invention relates to electrical equipment technical field, particularly relate to a kind of switch cubicle monitoring system.
Background technology
, there is internal fault in the power supply hinge of existing conventional/distribution Medium Voltage Switchgear Shi Quan factory subsidiary engine/electric power system
Time, if can promptly excise fault, the safe operation to full factory/distribution system is most important, but current Medium voltage switch or circuit breaker
The middle pressure bus of cabinet is still configured without any special protection, but taken into account by the relevant back-up protection of service entrance switch, and
Service entrance switch needs to cooperate with the protection of outlet switch, and the differential at least 300ms of general fast tripping protection time delay, very
To 500ms, and the cooperation of overcurrent protection is worse especially up to 12 seconds, so, station-service/distribution system is pressed on bus and occurred
Any fault the most at least want the time delay to excise, in other words, existing station-service is pressed bus can be in very first time excision fault
Protection is also a blank, and in view of the critical role of middle pressure bus, the time delay excision of any fault, is all that we are extremely unwilling to see
The situation arrived, because the various faults in switch cubicle, electric arc and high temperature produced by its breaking current, in making cabinet, gas is the most swollen
Swollen, 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, the arc light in the detection switch cubicle that it can be real-time
And current conditions, and keep the data detected are transferred to main control unit, main control unit is sentenced according to conventional data prediction
The disconnected fault occurred possibly sends trip operation signal to chopper, thus avoids 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, then is supplied to arc light unit by main control unit
With circuit unit running voltage, main control unit connects respectively to individual arc light unit, multiple current unit and multiple chopper, arc light
Unit, current unit and chopper are arranged in different switch cubicles.
The present invention is arc light unit and current unit can be distributed in different switch cubicles, the arc light detected or
Current signal is sent to main control unit, and main control unit is collected the data of these necessity and stored calculating, according to actual feelings
Condition output trip signal to chopper, if the light intensity that arc light unit monitors exceed setting value and current unit detects this
Switch cubicle electric current is not less than setting value, or the electric current that detects of current unit exceedes setting value and light that arc light unit monitors
Intensity is not less than setting value, and main control unit all will not export trip signal to chopper, and the signal that only both detect is super
When going out setting value, just can make trip operation, additionally arc light protecting system is equipped with an independent power supply, goes out at other system
During line 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 the lasting data that will detect pass
Be defeated by main control unit, according to conventional data prediction, main control unit judges that the fault occurred possibly sends tripping operation to chopper
Actuating signal, 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, break
Road device, power supply, described power supply is powered to main control unit, then is supplied to arc light unit and circuit unit work electricity by main control unit
Pressure, main control unit connects individual arc light unit, multiple current unit and multiple chopper respectively, arc light unit, current unit and
Chopper is arranged in different switch cubicles.
The present invention is arc light unit and current unit can be distributed in different switch cubicles, the arc light detected or
Current signal is sent to main control unit, and main control unit is collected the data of these necessity and stored calculating, according to actual feelings
Condition output trip signal to chopper, if the light intensity that arc light unit monitors exceed setting value and current unit detects this
Switch cubicle electric current is not less than setting value, or the electric current that detects of current unit exceedes setting value and light that arc light unit monitors
Intensity is not less than setting value, and main control unit all will not export trip signal to chopper, and the signal that only both detect is super
When going out setting value, just can make trip operation, additionally arc light protecting system is equipped with an independent power supply, goes out at other system
During line 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 the lasting data that will detect pass
Be defeated by main control unit, according to conventional data prediction, main control unit judges that the fault occurred possibly sends tripping operation to chopper
Actuating signal, thus avoid the damage set.
