Hello
Your question refers to Interlocking, blocking and signaling of a connection re-coupling of a switch or disconnector
Interlocking means maintaining a state permanently, this always referred to security; in electricity, if I interlock a switch it means that it cannot be operated.
The way to do it can be:
--manually, through an eye on a switch place a padlock (mechanical interlocking)
--automatic, for example a clock activates an electrical mechanism that prevents that switch from being opened or closed (electrical time interlock)
- local, is the example of mechanical interlocking with a padlock
--away, using electromechanical elements such as contactors to command a certain distance from where the interlocked switch is +.
- safety, which prevents this switch (or valve) from being opened for a change in pressure, for example
There are many more cases, but I think it has been explained
Blocking, is the impediment of performing an action (or change) with that switch, possible through a interlocking This is valid for any electricity circuit, steam water or any circuit of gas or fluid.
Control, is a manual or automatic system, through mechanical, electrical, hydraulic or pneumatic elements to achieve an action on a device to maneuver (control) .
A phase failure protector is an automatic interlock protector due to voltage failure.
A fan speed regulator is a control element.
wide your doubts.
