Method for protection of the solid fuel feeder motor and the system for protection of the solid fuel feeder motor

摘要

the subject of the invention is a way to protect the electric motor, which drives the fuel dispenser standing in central heating boilers for solid fuel and system to protect the engine. a protection engine is that during the working boiler is measured current supply motor (mot) feeder (under) fuel.in a situation where into (in) getting strange, hard body, dispenser (under) is stopped, thereby stopping the motor (mot), then the measuring block (p) establishes an increase in current intensity over rated value, and a microprocessor (m) off the power motor (mot), stops the si the whole system of fuel boiler becomes.a microprocessor (m) gives the signal to block signalling (s) and this triggers one or more signals that can fail. the signals may be issued jointly or in any configurations. the state is maintained until the failure causes. for the implementation of this mode controller (st) is connected with the motor (mot) through the system to protect the engine.system to protect the engine (mot) has no additional power source is powered from the power cable motor (mot). in one of the supply lines is a measuring block (p) for the measurement of the power supply line motor (mot). the measuring block (p) is connected with a switch (in) and a microprocessor (m) of the memory nieulotnu0105, for example. eeprom.a microprocessor (m) is also supplied from the power supply (), also supplied by power cable motor (mot). a microprocessor (m) is connected with a switch (in) on the supply line engine (mot) and with the block indicator (s).block signal (s) has an indicator (d) (buczek), optical (l) (led) and galvanically isolated interface (r), which is used for signalling through the external transmission channels, such as sms or e-mail. it is also connected with kasownikiem (k), for erasing state error zapamiu0119tywanego in memory nieulotnej microprocessor (m).
