In a kind of embodiment of the utility model, the protection control panel is equipped with run indicator, switching indicator light
With tripping indicator light, for showing the state of trip protection device and feeder controller.
In a kind of embodiment of the utility model, pressure button is additionally provided with the trip protection device, forces button to connect
Protection control panel is connect, hand-operated forced under feeder controller inspecting state can be switched to the operation of trip protection device.
Trip protection controller in the utility model has self-learning function, can give coal with your feeder master controller
Adjustment curve is measured, once learns permanent memory.
Trip protection controller can receive the instruction of DCS system, by controlling frequency converter come regulation motor rotating speed, so that
Reach the coal-supplying amount specified.
Trip protection controller has run indicator, switching indicator light and tripping indicator light, can show trip protection
The state of controller and feeder master controller.
Trip protection controller has the function of chute blockage trip protection, i.e., when feeder master controller trips because of chute blockage, no
It can be switched on trip protection controller and run, feeder is shut down at this time, meanwhile, pressure is switched to the operation of trip protection controller
When, as chute blockage and shut down.
Trip protection controller judges whether feeder master board loses by detecting feeder master board trip signal
Effect, automatically switches, while receives the instruction of DCS system, and motor operation is controlled by controlling frequency converter.Trip protection controller
Self study is carried out by the command signal and feeder master board output instruction signal of dynamic reception DCS system.
When trip protection controller carries out self study, it is achieved by the steps of：
1st, the pressure button on trip protection controller is pinned, opens being spaced apart to the power supply of trip protection controller, is tripped
Three indicator lights are lighted at the same time on protection controller, release button.
2nd, feeder is remotely started by DCS system, and specifies coal-supplying amount 1 (smaller value), wait feeder to stablize.
3rd, after feeder system is stablized, pressure button is clicked, red light 1 extinguishes, and illustrates that coal-supplying amount 1 records successfully.
4th, adjust DCS system and provide specified coal-supplying amount 2 (higher value), wait feeder to stablize.
5th, after feeder system is stablized, pressure button is clicked, if three lamps dodge at the same time, illustrates trip protection controller certainly
Learning success；If only red light 2 dodges, illustrate that coal-supplying amount 2 and 1 difference of coal-supplying amount are too small, the 4th, 5 steps must be repeated at this time.
6th, being spaced apart to the power supply of trip protection controller is disconnected, is reopened after 5 seconds.
When trip protection controller force switching, it is achieved by the steps of：
Under normal operation, pressure button, trip protection controller forced service are clicked, while red light 1 is lighted.
