Technical Note:
Safety circuit
Role:
Elevator can safely run to ensure that, in the elevator is equipped with many safety features.Each security components are only under normal circumstances, the lift to run, otherwise stop the lift immediately.
The so-called safety circuit is in the elevator safety components are equipped with a safety switch, all the safety switches in series to control a safety relay. Only if all safety switches are turned on in the case, the safety relay, elevator to get electricity to run.
l common security circuit switch are:
Room: control panel emergency stop switch, phase sequence relay, thermal relay, the governor switch
Wells said: upper limit switch, lower limit switch (some lift these two switches on the safety circuit, while others use both direct control switch power supply)
Pit: broken rope protection switch, emergency stop switch box maintenance pit, buffer switch
Inside the car: emergency stop switch control box
Jiaoding: safety window switches, safety gear switch, emergency stop switch box jiaoding overhaul...
