Abstract
The utility model relates to a piece of medium-voltage 12-kV complete equipment with the dual-power supply intelligent switching function. The complete equipment is composed of a motor servo system, an intelligent controller, an upper computer, an infrared sensor, a dual power supply incoming circuit, and a vacuum circuit breaker. And the mechanical structure of the complete equipment is characterized in that the equipment consists of a cabinet body, a pull-out type vacuum circuit breaker, and an isolation switch driven by the motor servo system. The intelligent controller receives a switching instruction of the upper computer; the infrared sensor collects real-time position signals of the vacuum circuit breaker and the isolation switch; and according to different situations, the intelligent controller controls the mechanical portion of the motor servo system to drive the switching position of the isolation switch, thereby realizing dual-path power supply circuit switching. Therefore, the accident factor caused by a human manipulation error can be avoided; the cost is lowered; and the installation space is saved. And the development requirement of the power automation and digitization transformer substation can be met.
Description
Technical field
The utility model is a kind of middle pressure 12kV the complete sets of equipment that configure intelligent double-power handoff functionality, and what relate to is power transmission and distribution design and manufacturing technology field, is applied to the power supplying and distributing equipment of electric power system generating, transmission of electricity, distribution, electric energy conversion and industrial enterprise etc.
Background technology
What the conventional 12kV the complete sets of equipment (being Medium Voltage Switchgear) that use in current domestic every profession and trade adopted when in realizing single busbar connection loop, power supply entering line switches is all that two incoming line cabinets side by side carry out electrical source exchange, and during operation, be all artificial on-site manual operation, extended electric power feeding time, increased the probability that manual operation accident occurs, also increased acquisition cost and cabinet installing space, more can not adapt to the trend of power automation and digital transformer substation development simultaneously.For this reason ad hoc counted that this power supply smart switches in be pressed into covering device.
Along with expanding economy, to Power System Intelligent, automation, high-speeding, safe, reliabilization, no matter the demand for development of miniaturization, be generating, transmission of electricity, distribution or electricity consumption, operation automation and intellectuality have all been proposed, safe, reliabilization, the requirement of miniaturization.When conventional power supply breaks down, can realization and the intelligence of stand-by power supply or generator switch, to guarantee reliability and the fail safe of power supply, also can switch according to the selectivity that need to carry out between two-way power supply of load.Sensing technology, information technology in addition, control technology, the innovation and development of motor servo system technology is pressed into covering device automation intelligent and operation and lays a good foundation in being also.
Summary of the invention
The purpose of this utility model is to commonly use the existing deficiency of 12kV the complete sets of equipment for above-mentioned realization when power supply entering line switches, and a kind of middle pressure 12kV the complete sets of equipment that double-power intelligent switches of realizing are provided.
The utility model is to realize by the following technical solutions object:
By a rotary single-pole double throw isolating switch being driven by motor servo system and a vacuum circuit-breaker are set in cabinet, intelligent controller in support IEC61850 agreement is received under the electrical source exchange instruction of host computer, the isolating switch that intelligent controller gathers according to transducer and vacuum circuit-breaker position state signal carry out after logic calculus judgement, determine that circuit breaker is in gate-dividing state, servo system is sent to instruction, by servo system mechanical part driving isolation switching over position, through infrared ray sensor, gather isolation switch blade gate position state, after intelligent controller judgement, sending signal closes a floodgate vacuum circuit-breaker, thereby the intelligence that reaches power supply entering line circuit is switched.In completing whole operating process, pass through infrared ray sensor Real-time Feedback isolating switch and vacuum circuit-breaker location status to intelligent controller, intelligent controller packing framing uploads to host computer.
Adopt the beneficial effect of the technical program: realize auto switching electric source, the accident of avoiding human operational error to cause, has reduced acquisition cost, has reduced installing space, can adapt to the requirement of power automation and digital transformer substation development.
