Abstract
The invention relates to an all-purpose circuit breaker with a circuit recloser and a control method. The invention is characterized in that: the invention includes a microprocessor, an under voltage release auxiliary node, a breaker state auxiliary node, a breaker fault alarming node and a breaker closing coil, as well as a recloser communication interface; the under voltage release auxiliary node, the breaker state auxiliary node and the breaker fault alarming node transmits signals into the input interface of the microprocessor, the output interface thereof transmits the control signals to the breaker closing coil and the recloser communication interface. The invention uses an intelligent control device with the microprocessor as a core, improves the sampling precision and guarantees the reclosing action reliability of the all-purpose breaker.
Description
Technical field
The invention belongs to a kind of low-voltage electrical apparatus, particularly relate to a kind of omnipotent breaker and control method that has reclosing device.
Background technology
Along with intelligent controller is widely used in the low-voltage electrical apparatus field, and still there is the electrical network flashing that causes by reasons such as thunders and lightnings in low-voltage distribution and the supply network.Auto recloser is mainly used in high-tension overhead line and relaying protection at present, realizes that by low-voltage controling appliance such device sampling precision is not high fully, and the reliability of device action is not high.And this " instantaneity " fault, will make the circuit breaker trip that has device for under-voltage releasing equipment.Because omnipotent breaker is applied on the main line of low voltage power distribution network, the tripping operation that this fault causes can cause large-area power failure, for national economy is brought massive losses.
Summary of the invention
The present invention provides a kind of sampling precision height for solving the technical problem that exists in the known technology, and device action has the omnipotent breaker and the control method of reclosing device reliably.
The present invention for solving the technical problem take that exists in the known technology about the technical scheme of the omnipotent breaker that has reclosing device is: it includes microprocessor, under-voltage release auxiliary node, circuit-breaker status auxiliary node, circuit breaker failure warning node and breaker closing coil, also includes the reclosing communication interface; Described under-voltage release auxiliary node, circuit-breaker status auxiliary node and circuit breaker failure warning node are input to the input port of microprocessor with signal, and the output port of described microprocessor outputs to breaker closing coil and reclosing communication interface with control signal.
The present invention for solving the technical problem take that exists in the known technology about the technical scheme of the omnipotent breaker control method that has reclosing device is: it includes the signal that microprocessor is imported by under-voltage release auxiliary node, circuit-breaker status auxiliary node and circuit breaker failure warning node, and its control flow is as follows:
(1) system initialization;
(2) microprocessor is read the state of described each auxiliary node;
(3) judge whether the under-voltage release auxiliary node has electricity, if there is electricity then to return step (2);
(4) if judge that the under-voltage release auxiliary node is not have electricity, then read the state of described each auxiliary node again;
(5) judge that whether circuit breaker is in "on" position, then reports to the police if be in "on" position;
(6) if not be in "on" position, judge further then whether circuit breaker is in the fault trip status, then report to the police if be in the fault trip status;
(7), judge further then whether the under-voltage release auxiliary node has electricity, if do not have electricity consumption then to return step (4) if not be in the fault trip status;
(8) if judge the under-voltage release auxiliary node electricity is arranged, then drive closing coil and make breaker closing.
Advantage and good effect that the present invention has are: owing to be to be the intelligence controlling device of core with the microprocessor, so just improved the precision of sampling, guaranteed the reliability of omnipotent breaker reclosing action.
Description of drawings
Fig. 1 is a circuit block diagram of the present invention;
Fig. 2 is a control flow chart of the present invention.
Embodiment
For further understanding content of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, under-voltage release auxiliary node, circuit-breaker status auxiliary node and circuit breaker failure warning node are input to the input port of microprocessor with signal, and the output port of microprocessor outputs to breaker closing coil and reclosing communication interface with control signal.
As shown in Figure 2, at first behind the system initialization, machine-readable all the auxiliary node states of monolithic, judge that the under voltage auxiliary node has state change process after, read states again is when being in "on" position or fault trip status as circuit breaker, just drive acoustic-optic alarm.When being in gate-dividing state or unfaulty conditions, when determining that once more device for under-voltage releasing equipment has electricity, just drive closing coil as circuit breaker.
