Abstract
The utility model relates to a switch cabinet comprehensive indicating device realized by a pure hardware circuit. The device comprises LED indicating lamps and multi-way switches. The number of the LED indicating lamps is N and the number of the multi-way switches is equal to the number of the LED indicating lamps. Each multi-way switch is provided with one switch blade and M contacts. The LED indicating lamps correspond to the switch blades of the multi-way switches one by one. The M contacts of each multi-way switch are respectively connected with M switching value input ends to realize random combination of corresponding relation. Compared with the prior art, the utility model has the advantages of low cost, high reliability and the like.
Description
Technical field
The utility model relates to a kind of indicating device, especially relates to a kind of comprehensive indicating device of being realized by pure hardware circuit of switch cubicle.
Background technology
The comprehensive indicating device of a kind of power switch cabinet (device is called for short in the back).This device is used for the various indoor switch cubicles of 3kV-35kV, detect and show the operating state of primary equipments such as circuit breaker, on-load switch, isolating switch, earthed switch in the high pressure complete set of equipments, and in conjunction with an electrical principle, dynamically, the operating state of display circuit intuitively.Device also has the Temperature and Humidity Control function of electrification in high voltage demonstration, automatic heating and dehumidification.
Device detect by switching value input and the display switch cabinet in the state information of primary equipment because that switch cubicle function and user are accustomed to is different, device is used for the LED of show state and the switching value corresponding relation between importing a variety of possibilities.
At present, as shown in Figure 1, the high pressure feeder line installs the luminescent device that shows isolation switch service position on the handcart type breaker, test position, breaker open operation position, breaker closing position, following isolation switch service position, test position cashier's office in a shop and is respectively LED1～LED6, DI1～DI6 is the numbering of six switching value inputs of access device, because there is multiple corresponding relation in client's use habit difference between LED and the DI.This brings very big inconvenience for the manufacturing of device, and general solution is to adopt microcontroller (MCU) to gather switching value input DI1～DI6, and when software control LED1～LED6 lights, and satisfies various possible corresponding relations.
Summary of the invention
The purpose of this utility model is exactly that a kind of low cost, highly reliable by the comprehensive indicating device of pure hard-wired switch cubicle is provided in order to overcome the defective that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of comprehensive indicating device of realizing by pure hardware circuit of switch cubicle, it is characterized in that, comprise LED light, variable connector, described LED light is provided with N, described variable connector is identical with the LED light number, each variable connector is provided with 1 plug-in strip, a M contact, and the plug-in strip of described LED light and variable connector connects one to one, and the M of a described variable connector contact is connected with M switching value input respectively.
Described N is 1～20 natural number.
Described M is 1～20 natural number.
Compared with prior art, the utlity model has following advantage:
1, low cost; 2, highly reliable; 3, saved the cost of MCU and peripheral circuit thereof; 4, easilier accepted, easily change by the user.
Description of drawings
Fig. 1 is the structural representation of prior art products;
Fig. 2 is the structural representation of 6 variable connectors of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 2, the utility model is a kind of comprehensive indicating device of being realized by pure hardware circuit of switch cubicle, corresponding relation with 6 LED and 6 road DI input is an example, comprise LED light, variable connector, described LED light is provided with 6, described variable connector is identical with the LED light number, each variable connector is provided with 1 plug-in strip, 6 contacts, the plug-in strip of described LED light and variable connector connects one to one, and 6 contacts of described variable connector are connected with 6 switching value inputs respectively.
As shown in Figure 1, LED1 is the indicator light of isolation switch test position on the handcart, LED2 is the indicator light of isolation switch service position on the handcart, LED3 is the indicator light of breaker closing position, LED4 is the indicator light of breaker open operation position, LED5 is the indicator light of isolation switch test position under the handcart, LED6 is the indicator light of isolation switch service position under the handcart, the control line of each LED light all is connected with each switching value input DI1～DI6 by multidiameter option switch, select corresponding relation between them arbitrarily by variable connector, even can realize a LED and multichannel DI input is corresponding or one road DI imports the specific (special) requirements corresponding with a plurality of LED.
