Description
Technical field
The utility model relates to a kind of line selection device for low current, especially relates to a kind of energy-saving line selection device for low current with sound and light alarm.
Background technology
Often need to power to corresponding production equipment configuration middle voltage distribution networks in large-scale workshop, compare general small distribution, middle voltage distribution networks needs to configure corresponding operator on duty and patrols whether it normally runs.Single-phase earthing is modal fault in middle voltage distribution networks, though system can continue to operate with failure after there is ground connection, because healthy phases voltage-to-ground raises, if process may develop into the threat of healthy phases insulation breakdown secondary phase fault not in time.Judge that ground loop is the basis getting rid of singlephase earth fault fast timely and accurately, realize judging that the protective device of earth fauit loops is commonly called Small Electric Current Earthing And Routing Device.General Small Electric Current Earthing And Routing Device can real-time monitoring system each section of bus residual voltage and Ge Lu outlet zero-sequence current, as shown in Figure 1, device there is stand by lamp, when system generation earth fault, stand by lamp is bright, but this stand by lamp is very little, be the light emitting diode of 3mm, brightness is low, when sending alarm, operator on duty is very difficult finds, easy failing to judge and extend fault-time, expands fault incidence, finally causes the loss of energy resource consumption.
Utility model content
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and a kind of energy-saving line selection device for low current with sound and light alarm is provided, fault handling efficiency can be provided, powered operation safety is joined in guarantee, has and installs the advantages such as simple, easy to operate.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of energy-saving line selection device for low current with sound and light alarm, comprise housing and be located at the circuit arrangement in housing, described circuit arrangement comprises controller, the data acquisition board of connection control device and the mutual induction of voltage circuit of difference connection data collection plate and Current Mutual Inductance circuit, also comprise the touch display screen of connection control device respectively, audible-visual annunciator, timer and wireless network card, described housing is provided with the stop button connecting audible-visual annunciator and timer, described wireless network card wireless connections supervisory control comuter.
Described audible-visual annunciator comprises LED and loudspeaker, and described LED and the equal connection control device of loudspeaker, described stop button connects LED and loudspeaker respectively.
Described LED is LED flashing light.
Described controller is ARM+DSP dual core processor.
Described wireless network card is wireless connections mobile device also.
Compared with prior art, the utility model has the following advantages:
One, fault handling efficiency is improved: operator on duty sends the alarm acoustic energy Timeliness coverage system failure by LED is bright with loudspeaker, if after sound and light alarm a period of time, operator on duty is not still had to operate, then timer feeds back to controller, controller sends further warning by wireless network card to long-range supervisory control comuter or mobile device, be convenient to timely handling failure, reduce energy loss.
Two, improve for distribution security of operation: the light emitting diode adopting 3mm compared to existing technology, the utility model is convenient to Timeliness coverage fault, processes in time, reduces coverage.
Three, install simply, easy to operate, treatment effeciency is high: simply can install on the basis of existing data acquisition board, mutual induction of voltage circuit and Current Mutual Inductance circuit, design touch display screen simultaneously and replace traditional keypad, can operate while display, convenient operation, controller adopts ARM+DSP dual core processor, the return data of data acquisition board, touch display screen, counter can be processed, assurance device stable operation simultaneously.
Accompanying drawing explanation
Fig. 1 is the front elevation of existing Small Electric Current Earthing And Routing Device;
Fig. 2 is the front elevation of the utility model housing;
Fig. 3 is the structural representation of the utility model circuit arrangement.
In figure: 1, controller, 2, data acquisition board, 3, mutual induction of voltage circuit, 4, Current Mutual Inductance circuit, 5, touch display screen, 6, audible-visual annunciator, 7, timer, 8, stop button, 9, wireless network card, 10, supervisory control comuter, 11, mobile device, 12, LED, 13, loudspeaker.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.The present embodiment is implemented premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As Fig. 2, shown in Fig. 3, a kind of energy-saving line selection device for low current with sound and light alarm comprises housing and is located at the circuit arrangement in housing, circuit arrangement comprises controller 1, the mutual induction of voltage circuit 3 of the data acquisition board 2 of connection control device 1 and respectively connection data collection plate 2 and Current Mutual Inductance circuit 4, also comprise the touch display screen 5 of connection control device 1 respectively, audible-visual annunciator 6, timer 7 and wireless network card 9, housing is provided with the stop button 8 connecting audible-visual annunciator 6 and timer 7, wireless network card 9 wireless connections supervisory control comuter 10 and/or mobile device 11 (such as mobile phone).Controller 1 is ARM+DSP dual core processor.
Audible-visual annunciator 6 comprises LED 12 and loudspeaker 13, and LED 12 and loudspeaker 13 all connection control devices 1, stop button 8 connects LED 12 and loudspeaker 13 respectively.Wherein, LED 12 is LED flashing light, compares light emitting diode, can provide more obvious alarm function, and loudspeaker 13 is toy trumpet.
The course of work:
When system generation earth fault, stand by lamp is bright, LED flashing light is glittering simultaneously, toy trumpet sends alarm call, timer 7 starts timing, operator on duty is the energy Timeliness coverage system failure just, and press stop button 8, stop the timing of timer 7, operator on duty is by operation touch display screen 5, understand failure message, thus be convenient to immediate analysis judgement, if after sound and light alarm a period of time, namely timer 7 reaches Preset Time, operator on duty is not still had to operate, then timer 7 feeds back to controller 1, controller 1 sends further warning by wireless network card 9 to long-range supervisory control comuter 10 or mobile device 11, overcome operator on duty to patrol the problem that leak brings.
