Description
Technical field
The protection and the control method that the present invention relates to a kind of distribution box, belong to distribution box product technical field.
Background technology
Distribution box all has the function of protective device, while normally moving, can connect or minute deenergizing by manual or automatic switch, when fault or irregular operating, by protective device, cuts off circuit or warning.Prior art adopts circuit breaker to protect short circuit or overload situations conventionally, and fault electrical equipment is excised from electric power system, to guarantee the continuation operation of non-faulty component.But the volume of circuit breaker is large, is arranged on and in distribution box, makes the volume of distribution box increase; And a circuit breaker can only be for the protection of a circuit, and the distribution box that is therefore applied to many route protections need to be installed a plurality of circuit breakers, has further increased the volume of distribution box.
Summary of the invention
The deficiency that the present invention exists for prior art just; a kind of protection and control method of distribution box are provided; can by the fault electrical equipment in Circuits System from main circuit fast disjunction go out, and the distribution box of application the method has the advantages that volume is little, so that installation and maintenance.
For addressing the above problem, the technical solution used in the present invention is as follows:
Protection and a control method, comprise the following steps:
Step 1, gather the current signal of each electrical equipment branch road and signal is transferred to processor;
Step 2, processor are resolved the current signal of each electrical equipment branch road, judge and send control signal;
Step 3, according to control signal, control the break-make of each electrical equipment branch road.
As the improvement of technique scheme, the external control of processor interface in described step 2, in order to require to arrange analysis judgment threshold value according to difference.
As the improvement of technique scheme, in described step 3, by relay or release, control the break-make of each electrical equipment branch road.
As the improvement of technique scheme, in described step 1, each electrical equipment branch road is provided with current signal collection and encoding device, and described encoding device is compiled into CAN signal by the current signal of collection and transmits; In described step 3, by decoding device, CAN signal is converted to for controlling the triggering signal of described relay or release work.
As the improvement of technique scheme, each electrical equipment branch road is provided with a single-chip microcomputer, and the decoding device in the encoding device in described step 1 and described step 3 is described single-chip microcomputer.
Compared with prior art, implementation result of the present invention is as follows in the present invention:
The protection of a kind of distribution box of the present invention and control method, can by the fault electrical equipment in Circuits System from main circuit fast disjunction go out, and the distribution box of application the method has the advantages that volume is little, is convenient to installation and maintenance; And by the application of CAN network, simplified the line arrangement in distribution box, only need a pair of stranded data/address bus mutually, one as output line, another root is as signal input line, avoided producing and disturbing between the signal transmssion line of each electrical equipment branch road, improved the transmission quality of current signal and control signal.
Embodiment
Content of the present invention is described below in conjunction with specific embodiments.
Specific embodiment one
Protection and a control method, comprise the following steps:
Step 1, gather the current signal of each electrical equipment branch road and signal is transferred to processor; By galvanometer, measure the current value of each electrical equipment branch road, and current value is delivered to processor.
Step 2, processor are resolved the current signal of each electrical equipment branch road, judge and send control signal; Whether processor is normal according to the threshold decision current value that sets in advance, and as extremely belonged to short circuit or overload, then whether corresponding judging is sent control signal and made relay or release work.
Step 3, according to control signal, control the break-make of each electrical equipment branch road; Receive after control signal, relay or release work make fault electrical equipment branch road break from main circuit.
Said method can by the fault electrical equipment in Circuits System from main circuit fast disjunction go out, and the distribution box of application the method has the advantages that volume is little, is convenient to installation and maintenance; But each electrical equipment branch road is provided with output line road and signal input line road, to connect processor, cause the line arrangement in distribution box comparatively complicated, easily chaotic, between the signal transmssion line of each electrical equipment branch road, also can produce interference, affect the transmission of current signal and control signal.
Specific embodiment two
Protection and a control method, comprise the following steps:
Step 1, gather the current signal of each electrical equipment branch road and signal is transferred to processor; By galvanometer, measure the current value of each electrical equipment branch road, the single-chip microcomputer of each electrical equipment branch road is compiled into CAN signal by current value and is delivered to processor.
Step 2, processor are resolved the current signal of each electrical equipment branch road, judge and send control signal; Whether processor is normal according to the threshold decision current value setting in advance, and as extremely belonged to short circuit or overload, then whether corresponding judging sends CAN control signal.
Step 3, according to control signal, control the break-make of each electrical equipment branch road; The single-chip microcomputer of each electrical equipment branch road sends triggering signal after receiving CAN control signal, makes relay or release work, thereby fault electrical equipment branch road is broken from main circuit.
Said method can by the fault electrical equipment in Circuits System from main circuit fast disjunction go out, and the distribution box of application the method has the advantages that volume is little, is convenient to installation and maintenance; And by the application of CAN network, simplified the line arrangement in distribution box, only need a pair of stranded data/address bus mutually, one as output line, another root is as signal input line, avoided producing and disturbing between the signal transmssion line of each electrical equipment branch road, improved the transmission quality of current signal and control signal.
Above content is detailed description made for the present invention in conjunction with specific embodiments, can not assert that the concrete enforcement of the present invention only limits to these explanations.For those skilled in the art, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to the scope of protection of the invention.
