The electric pneumatic valve (2) left in pass (14) and the air-valve device (100) is controlled.
9. contact net power supply air valve control system according to claim 8, it is characterised in that：When the control device
(15) detect that the pantograph branch air pressure of the first electric contact air gauge (6) feedback is less than the first setting value or described the
The main road air pressure of two electric contact air gauges (7) feedback is less than the second setting value, and the control device (15) judges compressed air hose
Road air pressure is too low and is in abnormality, and controls the high-voltage circuitbreaker (13) separating brake first, then controls the electric pneumatic valve (2)
It closes, cuts off the compressed air gas source of pantograph branch；After the compressed air gas source of pantograph valve plate (1) detection without input
It is exhausted, controls the pantograph (12) drop bow, to complete compressed air line low pressure protection act, avoid compression empty
Gas air pressure deficiency causes the pantograph (12) surprisingly drop bow.
10. contact net power supply air valve control system according to claim 8 or claim 9, it is characterised in that：Work as compressed air
The air pressure of pipeline, which meets, to impose a condition, by the drive for being integrated in the high-voltage circuitbreaker (13) and high voltage isolator (14) inside
Motivation structure controls high-voltage circuitbreaker (13) respectively and the main contact of high voltage isolator (14) carries out combined floodgate or separating brake action.
