Description

(54) DEVICE FOR AUTOMATIC LOCKING CURRENT CURRENT ACCESSORIES

one

The invention relates to the field of electrified transport and can be used in control devices for current collectors, for example, at points of contact wire rupture.

A device for automatically blocking a current collector of a vehicle, preferably at the points of rupture of the contact wire, comprising an element mounted on the contact wire for rejecting the current collector, and a vehicle current limiter 1.

However, the device has insufficient reliability and efficiency, since it is necessary to stop the vehicle and switch the current collector at the points of break of the contact wire.

The purpose of the invention is to increase reliability and efficiency by eliminating vehicle stops.

To achieve the goal, the device is equipped with a vehicle current sensor connected mechanically to the current receiver, a current collector deflection sensor, a voltage sensor in the contact wire, and an element, whose inputs are connected respectively to the voltage sensor outputs in the contact wire and the current receiver deflection sensor, and the output is connected to the input current collector stroke limiter.

The drawing shows a block diagram of the device.

The device consists of an element 1 for fixing the current collector, made of a dielectric in the form of segments, and installed at the break points of the contact wire 2 in such a way that its convex part mechanically contacts the upper part of the current collector 3, which is mechanically connected , for example, a limit switch with latching position, the output of which is connected to one input of the element 5, to the second input of which is connected the output of the voltage sensor 6 in the contact wire, electrically with united with the current collector 3, the output element And 5 is connected to the input of the limiter 7 of the current collector stroke, and a solenoid with a movable spring-loaded latching core 8 is used as the current limiter of the current collector. The locking device works as follows. With the passage of the electric locomotive under the loading point of the current collector 3, the slip along the contact wire 2 falls on the element 1 (right in the drawing). In this case, the supply voltage disappears, the voltage sensor 6 in the contact wire operates, and the absence of voltage signal is sent to one of the inputs of the element 5. Further deviation of the current collector 3 triggers the deviation sensor 4, the signal from which arrives at the second input of the element 5. When the signals from the voltage sensor 6 coincide with the deviation sensor 4, the output of the element 5 appears at the input of the stroke limiter 7. The stroke limiter 7 is activated and its latch 8 limits the stroke of the current collector 3 from above. In this case, the current collector has the ability to rise above the point at which the deflection sensor triggered, but not less than the level of the ends of the contact wire at the break points of the contact network. The second deflecting element (left in the drawing) again deflects the current collector 3, the deflection sensor 4 is disconnected and the output of the AND element 5 to the input of the stroke limiter 7 receives a signal that turns off the stroke limiter 7, and releases the current collector 3 for slit 8. Formula of the invention. A device for automatically blocking a current collector of a vehicle, preferably at the points of rupture of the contact wire, containing an element mounted on the contact wire to deflect the current collector, and on the vehicle limited The current collector stroke, characterized in that for the sake of reliability and efficiency by eliminating the vehicle stops, it is fitted with a vehicle mounted mechanically connected to the current collector by a current collector deflection sensor, a voltage sensor in the contact wire and an element whose inputs are connected respectively to the voltage sensor outputs in the contact wire and the current collector deviation sensor, and the output is connected to the input of the current limiter of the current collector.
