Accompanying drawing explanation
Fig. 1 is the circuit diagram of the utility model mimic-disconnecting switch embodiment.
Embodiment
Be described in detail below in conjunction with the embodiment of accompanying drawing to the utility model mimic-disconnecting switch, wherein in the utility model, first, second word such as grade, just to distinguishing element device, does not limit with order the number of components and parts.
As shown in Figure 1, a kind of mimic-disconnecting switch, comprises switch knob SH, opening button ST, magnetic latching relay CBJ, electromagnetic relay MJ, time relay TJ, the first divider resistance R1, the second divider resistance R3, the first shunt resistance R2, the second shunt resistance R4; Wherein the model of magnetic latching relay CBJ can be ST2-L2-DC48V etc.
The normally closed contact of the pull-in winding CBJ1 of switch knob SH, the first divider resistance R1, magnetic latching relay CBJ, the first normally closed contact MJ1 of electromagnetic relay MJ, time relay TJ is connected between power positive cathode after connecting successively; First shunt resistance R2 is in parallel with the pull-in winding CBJ1 of the first divider resistance R1 connected, magnetic latching relay CBJ;
After the release coil CBJ2 of opening button ST, the second divider resistance R3, magnetic latching relay CBJ, the first normally opened contact MJ2 of electromagnetic relay MJ connect successively, be connected between power positive cathode; Second shunt resistance R4 is in parallel with the release coil CBJ2 of the second divider resistance R3 connected, magnetic latching relay CBJ;
The normally opened contact of magnetic latching relay CBJ is connected between power positive cathode after connecting with the actuation coil of electromagnetic relay MJ; After the second normally closed contact MJ3 of electromagnetic relay MJ connects with the actuation coil of time relay TJ, in parallel with the actuation coil of electromagnetic relay MJ.
As shown in Figure 1, mimic-disconnecting switch can also comprise combined floodgate pilot lamp HD and separating brake pilot lamp TD, and described combined floodgate pilot lamp HD can be red light, and described separating brake pilot lamp HD can be green light, also combined floodgate pilot lamp HD and separating brake pilot lamp TD can be set to other color.After the second normally opened contact MJ4 of electromagnetic relay MJ connects with combined floodgate pilot lamp HD, be connected between power positive cathode; After the 3rd normally closed contact MJ5 of electromagnetic relay MJ connects with separating brake pilot lamp TD, be connected between power positive cathode.Can the current state of display simulation isolating switch by combined floodgate pilot lamp HD and separating brake pilot lamp TD, and closing loop is monitored.
In order to improve the applicability of mimic-disconnecting switch, as shown in Figure 1, switching signal input end HZ is connected between switch knob SH and the first divider resistance R1, and sub-gate signal input end TZ is connected between opening button ST and the second divider resistance R3.Make mimic-disconnecting switch can not only manual divide-shut brake, corresponding actions be carried out in the breaker tripping and closing order that can also accept protective device.
In process of the test, when mimic-disconnecting switch is in gate-dividing state, the normally closed contact MJ1 of electromagnetic relay MJ, the normally closed contact of time relay TJ are closed.When switch knob SH presses, or switching signal input end HZ receives one when having the pulse voltage signal of one fixed width, the pull-in winding CBJ1 of magnetic latching relay CBJ is energized, magnetic latching relay CBJ state transfer, the normally opened contact of magnetic latching relay CBJ closes, and the magnetic force produced by the permanent magnet in magnetic latching relay CBJ iron core remains on attracting state.The then actuation coil energising of time relay TJ, the normally closed contact of time relay TJ disconnects; The actuation coil energising of electromagnetic relay MJ, normally closed contact MJ1, MJ3, MJ5 of electromagnetic relay MJ disconnect, and normally opened contact MJ2, MJ4 are closed, and mimic-disconnecting switch changes "on" position into by gate-dividing state, and combined floodgate pilot lamp HD lights, and separating brake pilot lamp TD extinguishes.
After mimic-disconnecting switch closes a floodgate, because the normally closed contact MJ3 of electromagnetic relay MJ disconnects, the actuation coil dead electricity of time relay TJ, the normally closed contact of time relay TJ closes after time delay t second, the process can not closed a floodgate during operating mechanism energy storage after real simulation primary cut-out closes a floodgate, wherein parametric t can be arranged on time relay TJ according to test demand.Mimic-disconnecting switch is when "on" position, and the normally opened contact MJ2 of electromagnetic relay MJ closes, and trip(ping) circuit is in standby condition.
When opening button ST presses, or trip signal input end TZ receives one when having the pulse voltage signal of one fixed width, the release coil CBJ2 of magnetic latching relay CBJ is energized, and magnetic latching relay CBJ state transfer, the normally opened contact of magnetic latching relay CBJ disconnects and keeps.The actuation coil dead electricity of electromagnetic relay MJ this moment, normally closed contact MJ1, MJ3, MJ5 of electromagnetic relay MJ transfer to closed, and normally opened contact MJ2, MJ4 transfer disconnection to, and mimic-disconnecting switch changes gate-dividing state into by "on" position, combined floodgate pilot lamp HD extinguishes, and separating brake pilot lamp TD lights.
Mimic-disconnecting switch is when gate-dividing state, and the normally closed contact MJ1 of electromagnetic relay MJ closes.If when the normally closed contact of time relay TJ is also in closure state, closing circuit is in standby condition.In addition, mimic-disconnecting switch is when gate-dividing state, and the normally opened contact of magnetic latching relay CBJ disconnects, and the normally closed contact MJ3 of electromagnetic relay MJ closes, the actuation coil of time relay TJ can upper once close a floodgate time trigger.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
