The fault controller in this embodiment includes main functional specifications, for example:
controlling in situ: the remote/cutting/local switch is set to be local, and the knobs of the A phase, the B phase, the C phase, the AB phase, the BC phase and the AC phase on the panel are effective.
The resistance adjusting knobs for the faults of the A phase, the B phase, the C phase, the AB phase, the BC phase and the AC phase are adjusted to be different resistance values, so that different fault scenes (such as single-phase grounding, two-phase short-circuit faults, two-phase short-circuit grounding faults, three-phase short-circuit faults and three-phase short-circuit grounding faults) can be realized.
Remote control: the change-over switch is set to be far, the operation of a transition resistance setting knob on the panel is invalid, and different fault scenes are simulated by setting related parameters through a dynamic simulation platform TCP.
Cutting: when the 'remote/cut-off/local' change-over switch is set to 'cut-off', no matter what 'local' or 'remote' control is adopted before, all the operations are failed, the fault connection mode is disconnected, and the indicator light is completely turned off.
IGIR-B code pair: the time synchronization is externally connected through the serial port RS485+ and RS 485-and is performed with the time synchronization preposed.
Specific examples are as follows:
the local control can set the local/cutting/remote switch to local through the panel operation knob, realize different fault scenes by selecting the knobs of A phase, B phase, C phase, AB phase, BC phase and AC phase, and indicate the current state through the indicator light.
When a single-phase earth fault mode needs to be simulated, taking an A-phase earth fault through a0 omega resistor as an example, the setting steps are as follows: firstly, setting a rotary 'local/cutting/far' change-over switch as 'local'; and secondly, rotating the knob of the phase A to set the knob of the phase A as a resistor of 0 omega, and lighting a corresponding indicator light of 0 omega above the knob of the phase A to realize a fault scene that the phase A is grounded through the resistor of 0 omega.
When a two-phase short-circuit fault mode needs to be simulated, taking an AB phase short-circuit fault through a0 omega resistor as an example, the setting steps are as follows: firstly, setting a rotary 'local/cutting/far' change-over switch as 'local'; and secondly, rotating the AB phase knob to set the AB phase knob as a0 omega resistor, and enabling a0 omega indicator lamp corresponding to the right side of the AB phase knob to be on, so that an AB phase short circuit fault scene through the 0 omega resistor is realized.
When a two-phase short circuit ground fault mode needs to be simulated, namely a two-phase resistance short circuit and a ground fault of each single phase in the two phases, taking an example that an AB phase is short circuit through a0 omega resistance and an A phase and a B phase are ground fault through the 0 omega resistance, the setting steps are as follows: firstly, setting a rotary 'local/cutting/far' change-over switch as 'local'; secondly, rotating the AB phase knob to set the AB phase knob as a0 omega resistor, and enabling a0 omega indicator lamp corresponding to the right side of the AB phase knob to be on, so that an AB phase short circuit fault scene through the 0 omega resistor is realized; thirdly, rotating the knob of the phase A to set the knob of the phase A as a resistor of 0 omega, and enabling a corresponding indicator light of 0 omega above the knob of the phase A to be on so as to realize a fault scene that the phase A is grounded through the resistor of 0 omega; and fourthly, rotating the knob of the 'B phase' to set the knob of the '0 omega' resistor, and enabling the indicator lamp of the '0 omega' corresponding to the knob of the 'B phase' to be on, so as to realize the fault scene of the 'B phase' grounded through the resistor of the '0 omega'.
When a three-phase short-circuit fault mode needs to be simulated, taking an ABC phase short-circuit fault through a0 omega resistor as an example, the setting steps are as follows: firstly, setting a rotary 'local/cutting/far' change-over switch as 'local'; secondly, rotating the AB phase knob to set the AB phase knob as a0 omega resistor, and enabling a0 omega indicator lamp corresponding to the right side of the AB phase knob to be on, so that an AB phase short circuit fault scene through the 0 omega resistor is realized; thirdly, rotating the BC phase knob to set the BC phase knob to be 0 omega resistor, and enabling a0 omega indicator lamp corresponding to the right side of the BC phase knob to be on, so that a BC phase short circuit fault scene through the 0 omega resistor is realized; and fourthly, rotating the 'AC phase' knob to set the '0 omega' resistor, and enabling a '0 omega' indicator lamp corresponding to the right side of the 'AC phase' knob to be on, so that the 'AC phase' is in a short-circuit fault scene through the '0 omega' resistor.
