Description

The indicating fault unit of intelligent breaker and intelligent breaker

Technical field

This utility model relates to chopper, particularly relates to the indicating fault unit of a kind of intelligent breaker.

Background technology

Low-voltage electrical distribution system typically there will be the faults such as overload, short circuit, ground connection, and circuit and power-supply device can be caused harm greatly by this kind of fault.At present, the low-voltage circuit breaker as power distribution protection has realized intelligent protection function the most, and the intelligent controller as chopper core component serves considerable effect.By the man machine interface of intelligent controller, user can inquire about the fault message of chopper clearly, but, the indicating mode of fault is relevant to the display mode of controller, for traditional controller: if controller is liquid crystal display, a monochromatic LED lamp is the most typically used to coordinate liquid crystal display to indicate a kind of fault；If controller is charactron or light pillar type shows, then the instruction of fault typically requires two monochromatic LED lamps and indicates a kind of fault, and one is used for indicating fault type, and another is used for indicating which phase line is fault occur in.Thereby result in instruction complexity, use element too much, high expensive, and it is unfavorable for the miniaturization of intelligent controller.

Utility model content

Technical problem to be solved in the utility model is to overcome prior art not enough, it is provided that the indicating fault unit of a kind of intelligent breaker, can indicating intelligent chopper is monitored intuitively and accurately fault type and position, and circuit is simple, it is achieved low cost.

This utility model is concrete by the following technical solutions:

A kind of indicating fault unit of intelligent breaker, the fault category monitored for indicating intelligent chopper and fault phase, described indicating fault unit includes the intelligent controller electrical connection with intelligent breaker and can monitor, with intelligent breaker, one group of tri-colour LED that fault category number is identical, three phase place one_to_one corresponding of each tri-colour LED correspondence one fault category, the light of three kinds of colors of each tri-colour LED and the monitored major loop of intelligent breaker.

Preferably, described tri-colour LED is three-color LED light.

Preferably, described tri-colour LED is red, yellow, and green lamp.

Further, this indicating fault unit also includes for showing fault current or the display unit of false voltage numerical value；The preferred charactron of described display unit.

A kind of intelligent breaker can also be obtained, including indicating fault unit described in intelligent controller and arbitrary technical scheme according to identical invention thinking.

Compared to existing technology, this utility model has the advantages that

This utility model utilizes different tri-colour LEDs to show different fault types, and utilize three kinds of colors to distinguish fault occurs which phase in A, B, C three-phase, on the one hand understanding fault type and abort situation with can making user's quicklook, on the other hand circuit is simple, it is achieved low cost.

Accompanying drawing explanation

Fig. 1 is the control panel schematic diagram of one embodiment of this utility model intelligent breaker；

Fig. 2 is the circuit theory schematic diagram of one embodiment of this utility model.

Detailed description of the invention

Below in conjunction with the accompanying drawings the technical solution of the utility model is described in detail:

Thinking of the present utility model is to utilize to be readily available on market and cheap tri-colour LED is to carry out the indicating fault of intelligent breaker; the fault type number can monitored according to intelligent breaker; the tri-colour LED of configuration respective numbers; each tri-colour LED correspondence one fault category; the intrinsic three kinds of coloured light of each tri-colour LED then with three phase place one_to_one corresponding of protected major loop, for indicating fault occurs which phase in A, B, C three-phase.

Tri-colour LED therein preferably employs currently used most three-color LED light, such as red, yellow, and green LED.Further, it is also possible to combine the traditional display modes such as liquid crystal display, digital-scroll technique, Bar graphic display further in this utility model, the numerical value of fault current or false voltage is shown.

For the ease of public understanding, with a specific embodiment, technical solutions of the utility model are described in detail below.

Fig. 1 shows the control panel of intelligent breaker in the present embodiment, and Fig. 2 shows the intelligent controller of this intelligent breaker and the basic circuit principle of fault display unit.As shown in Figure 1 and Figure 2, fault display unit in the present embodiment includes three three-color LED lights being arranged on intelligent breaker control panel and a charactron shown for numerical value, and three three-color LED lights correspond respectively to long delay, short time delay, move this three classes fault wink；It is, of course, also possible to there is other fault type such as ground protection, earth leakage protective, the quantity of corresponding three-color LED light can be set flexibly according to the fault type that intelligent breaker can be monitored.Also there is on intelligent breaker control panel characteristic protection curve, represent long delay, short time delay respectively, move three section protection characteristic wink, as Fig. 1 black matrix thick line represents.Certainly, characteristic protection curve can also have other such as the curve of the fault types such as ground protection.Wherein Ir1, Ir2, Ir3 represent long delay, short time delay, move three section protection characterisitic parameter wink.Three three-color LED lights of the present utility model lay respectively on three sections of characteristic protection curves, as shown in Figure 1, it is possible to tell the fault type of appearance clearly.Three three-color LED lights can also be arranged at characteristic protection curve top and be horizontally mounted side by side, it is also possible to three three-color LED lights be arranged at characteristic protection curve bottom and be horizontally mounted side by side.User can utilize code switch to be adjusted by the relevant Protection parameters of intelligent breaker; LED1, LED2, LED3 are the most frequently used red, yellow, and green lamp (being certainly used as other color tri coloured lantern); red colored lamp flicker represents that fault occurs in A phase; amber light flicker represents that fault occurs in B phase, and green light flicker represents that fault occurs in C phase.

A, B, C phase receives the signal of telecommunication in circuit by transformer, and (not shown) after signal processing circuit, transferring data to the microprocessor in intelligent controller, microprocessor exports fault-signal after relevant treatment, if long delay fault occurs in circuit A phase, then control LED1 red light and start flicker, if fault is in B phase, then amber light flicker, C phase fault then green light flashes, scintillation time is the delay time that fault is adjusted, and keeps Chang Liang afterwards；Same situation, if short delay fault occurs, then LED2 flicker；Occur wink moving fault, then LED3 flicker.Meanwhile, charactron demonstrates the size of fault current, user it is clear that.

This utility model utilizes a tri-colour LED directly to indicate type and the circuit of fault appearance of a kind of fault, user's First view can be allowed just to understand, and which phase line the fault type occurred and fault occur on, simplify the circuit of instruction fault, decrease use element, be conducive to the miniaturization of intelligent breaker, and cost can be reduced.And indicating fault mode of the present utility model can apply to the controller of various display mode, range is wide.
