According to electric current flows along contact net-pantograph-current transformer-motor-rail, if occurring bow net offline, flows through the electric current of pantograph
Will vanishing, but therefore electric current is alternating current, is also possible to be zero when not offline, but now its differential value is also zero, therefore can
To detect bow net off-line state.
(2) electric-resistivity method
This method leads line resistance according to bow net and becomes big principle suddenly when offline is detected, once occur offline existing
As resistance becomes big between bow net, and electric current diminishes, and then detects off-lined signal.
(3) capacitance resistance method
This method is, in measurement, two capacitors and a resistance to be accessed between pantograph and ground, capacitor is utilized
Pantograph voltage is measured, resistance measurement pantograph electric current is examined by detecting the change of the voltage current waveform when bow net is offline
Survey off-line state.
(4) pressure detecting method
This method is, by installing pressure sensor in pantograph, bow net contact pressure to be detected, so as to judge
Whether occur offline.
