What is a mechanical interlock?
Mechanical interlock devices are electrical receptacles that allow compatible plugs to be attached only when the power is turned off. They also prevent the plug from being removed from the receptacle while the power is on.
What is interlock switchgear?
Interlocks are mounted to the switchgear to lock in either the open or closed position, or in some cases both. Once the switchgear has been operated a key is released and taken to the next interlock in the sequence.
Where can interlock switches be found?
Manufacturing and industrial environments use interlock switches in machinery of all types. Interlock switches are also used in the domestic environment, in devices such as automated gates or slam-lock doors.
How does mechanical interlock work in contactor?
Mechanical Interlock General: Type S contactors or starters can be mechanically interlocked so that only one device is energized at a time. The mechanical interlock is an interference (non-jamming) type, locking at the beginning of the stroke of any starter or contactor.
What is interlock wiring?
To interconnect the motor circuit in such a way, in which the second motor will not start until the first one run likewise the third one motor will not run unless the second one run and so on. This kind of motor circuit connection is called interlocking.
What is the purpose of the interlock?
An interlock is a type of device that is used to prevent undesirable conditions in machines, which may include mechanical or electronic systems or devices. In almost all applications, it is utilized to aid in preventing machines from causing harm to the machine itself or to the operators.
What is a interlock circuit?
An interlock device is designed to allow a generator to provide backup power in such a way that it (a) prevents main and generator power to be connected at the same time, and (b) allows circuit breakers to operate normally without interference in the event of an overload condition.
What are the types of interlocking?
Interlocking types
- Mechanical interlocking.
- Electro-mechanical interlocking.
- Relay interlocking.
- Electronic interlocking.
What is the interlocking method?
The interlocking technique, called latch-hooking or root flipping, requires pulling the ends of a section of hair (or a dreadlock) through the root of that same section. This creates a “lock” of sorts and holds the hair in that position while a dreadlock forms.
What is the purpose of a interlock?
In most applications, an interlock is used to help prevent a machine from harming its operator or damaging itself by preventing one element from changing state due to the state of another element, and vice versa.
