Abstract
A remotely controlled simulated linear circuit breaker capable of being set and reset remotely, and manually operated. Control signals are received by an on-board controller circuit card assembly. The signals will cause a plunger located in a solenoid housing to do one of two things. Either it will be extracted out of the solenoid housing, thereby popping the simulated circuit breaker, or it will be pulled into the solenoid housing, thereby resetting the simulated circuit breaker. In addition, the position of the switch is remotely sensed.
Claims34
A remotely controlled simulated linear circuit breaker assembly comprising:
- a solenoid having a first and a second lead;
- a housing;
- a plunger seated inside said housing;
- a compression spring reciprocally connected to said plunger;
- a cap attached to one end of said plunger, said cap allowing for manual operation of said remotely controlled simulated linear circuit breaker assembly;
- a controller circuit card assembly having a first input and a second input, a first output connected and electrically coupled to said first lead of said solenoid, and a second output connected and electrically coupled to said second lead of said solenoid,
- whereby when a control voltage is applied to said first input of said controller circuit card assembly, said plunger is extracted from said solenoid housing by said spring, and when a control voltage is applied to said second input of said controller circuit card assembly, said plunger is pulled into said solenoid housing.
A method of controlling a remotely controlled simulated linear circuit breaker assembly comprising the steps of:
- applying a current through a solenoid winding in either a forward or a reverse direction;
- extracting a plunger from or pushing a plunger into a solenoid housing respectively;
- setting or resetting the remotely controlled simulated linear circuit breaker assembly respectively;
- and
- sensing a beam of light to determine the position of said simulated linear circuit breaker assembly.
A maintenance trainer system comprising a plurality of remotely controlled simulated linear circuit breaker assemblies, wherein each of said remotely controlled simulated linear circuit breaker assemblies comprises:
- a solenoid having a first and a second lead;
- a housing;
- a plunger seated inside said housing;
- a compression spring reciprocally connected to said plunger;
- a cap attached to one end of said plunger, said cap allowing for manual operation of said remotely controlled simulated linear circuit breaker assembly;
- a controller circuit card assembly having a first input and a second input, a first output connected and electrically coupled to said first lead of said solenoid, and a second output connected and electrically coupled to said second lead of said solenoid,
