Abstract
The utility model relates to a universal circuit breaker with a reclosing device which is characterized in that the circuit breaker includes a microprocessor, a deficient voltage releaser auxiliary node, a circuit breaker state auxiliary node, a circuit breaker fault alarming node and a circuit breaker reclosing coil. The circuit breaker also includes a reclosing communication interface. The deficient voltage releaser auxiliary node, the circuit breaker state auxiliary node and the circuit breaker fault alarming node input signals into the input interface of the microprocessor. The output interface of the microprocessor outputs control signals to the circuit breaker reclosing coil and a closing communicating interface. With the microprocessor which is used as the core, the intelligent control device of the utility model can improve the sampling precision and ensures the reliability of the reclosing of the circuit breaker.
Description
Technical field
The utility model belongs to a kind of low-voltage electrical apparatus, particularly relates to a kind of omnipotent breaker 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 utility model provides a kind of control method that adds microprocessor just can the sampling precision height for solving the technical problem that exists in the known technology, and device action has the omnipotent breaker of reclosing device reliably.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology 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.
Advantage and the good effect that the utlity model has are: owing to be to be the intelligence controlling device of core with the microprocessor, adding the control flow step of microprocessor like this, just can improve the precision of its sampling, guarantee the reliability of omnipotent breaker reclosing action.
Description of drawings
Fig. 1 is a circuit block diagram of the present utility model.
Embodiment
For further understanding summary of the invention of the present utility model, 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 the status signal of each node, and the output port of microprocessor outputs to breaker closing coil and reclosing communication interface with the control signal after judgment processing.
