In an embodiment of the present disclosure, there is provided a pantograph control method, as shown in fig. 1, the pantograph control method may include:
step S110, lifting the pantograph to enable the pantograph to be in contact with a contact net and to receive current, wherein the contact pressure between the pantograph and the contact net is a first pressure;
step S120, detecting the current system of the contact network;
and step S130, controlling a valve plate of the pantograph according to the detected current system to adjust the gas flow of the compressed gas for pantograph lifting so as to adjust the contact pressure between the pantograph and the contact network.
In the pantograph control method according to the embodiment of the present disclosure, first, the pantograph is raised so as to be in contact with a catenary and receive current; secondly, detecting the current system (alternating current or direct current) of the contact network; and finally, controlling a valve plate of the pantograph according to the current system to adjust the flow of compressed gas for lifting the pantograph so as to adjust the contact pressure between the pantograph and the contact network. Because different current systems have different requirements on the contact pressure between the pantograph and the contact network, the pantograph control method enables the pantograph to automatically adjust the contact pressure between the pantograph and the contact network according to the current systems of the contact network, and further enables the pantograph to receive current under various current systems.
A pantograph control method according to an embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings:
step S110, the pantograph is raised so that the pantograph contacts and receives current from the overhead line system, and a contact pressure between the pantograph and the overhead line system is a first pressure.
The pantograph on the roof of the electric locomotive can be in contact with the contact network and receive current after rising, because different current systems (an alternating current mode and a direct current mode) have different requirements on contact pressure between the pantograph and the contact network, specifically, the contact pressure in the alternating current mode is smaller than that in the direct current mode, at the moment, the current system of the contact network can be acquiescent to be in the alternating current mode, and the contact pressure (first pressure) between the pantograph and the contact network is equal to the corresponding contact pressure in the alternating current mode, so that the adjustment times of the pantograph are reduced, and the working efficiency is improved.
And S120, detecting the current system of the overhead line system.
After the pantograph is in contact with and receives current from the catenary, a current system detector can be used to detect a current system (an alternating current mode and a direct current mode) of the catenary, for example, the current system detector may be a universal meter or an oscilloscope, and of course, the current system detector may also be a high-voltage detection device of an electric locomotive, and the current system detector is not particularly limited herein.
And step S130, controlling the pantograph to be raised or lowered according to the detected current system so as to adjust the contact pressure between the pantograph and the overhead contact system.
Specifically, when the detected current pattern is an alternating current pattern, the flow rate of the compressed gas passing through the valve plate is kept constant, so as to keep the contact pressure (first pressure) between the pantograph and the overhead contact system constant; when the current system of the contact network is in a direct current mode, the valve plate is controlled to increase the flow rate of the compressed gas for pantograph lifting so as to increase the contact pressure between the pantograph and the contact network until the contact pressure is a second pressure, obviously, the second pressure is greater than the first pressure, and the specific values of the first pressure and the second pressure are subject to meeting the actual use requirements, and are not described in detail herein.
After step S130, the pantograph control method of the embodiment of the present disclosure may further include:
step S140, confirming that the current system of the catenary is matched with the first pressure/the second pressure, specifically, comparing the detection signal of the current system detector with the corresponding contact pressure (the first pressure/the first pressure), that is, comparing the current system with the first pressure/the second pressure, and when the current system is matched with the first pressure/the second pressure, opening the authority to the operator so that the operator can start the electric locomotive.
There is also provided in an embodiment of the present disclosure a pantograph, as shown in fig. 2, which may include a pantograph head 1, a pantograph lifting assembly 2, a current system detector and a controller, wherein:
the sliding plate 10 on the bow 1 can contact with a contact net and receive current; the pantograph lifting assembly 2 connected with the pantograph head 1 is provided with a valve plate 220, and the valve plate 220 can adjust the air flow of compressed air for pantograph lifting so as to lift or lower the pantograph head 1; after the current system detector determines the current system (ac or dc) of the contact network, the controller can control the valve plate 220 to adjust the flow rate of the compressed gas for pantograph lifting according to the current system so as to adjust the contact pressure between the sliding plate 10 and the contact network, that is, the pantograph can adjust the contact pressure between the sliding plate 10 and the contact network according to the current system of the contact network, and further the pantograph can receive current in multiple current systems.
The following describes each component of the pantograph according to the embodiment of the present disclosure in detail with reference to the accompanying drawings:
as shown in fig. 2, the bow 1 may have a slide plate 10, which slide plate 10 is intended to be in contact with and to receive current from an overhead line. For example, the number of the sliding plates 10 may be four, and the number of the sliding plates 10 in the prior art is only two, so that, under the condition that the contact pressure between the sliding plates 10 and the catenary is not changed, the contact area between the pantograph head 1 with the four sliding plates 10 and the catenary is increased by times, and then the pantograph of the present application can obtain and transmit a larger current in a direct current mode.
Certainly, this bow 1 still can include parts such as bracket, extension spring, bow end axle and pivot, as shown in fig. 2, the quantity of bracket is four, and four slides 10 accessible bolt fastening are at the both ends of every bracket, and the bracket passes through the extension spring and installs on the bow end axle, and this bow end axle links to each other with the pivot again to make slide 10 can follow the trend adjustment turned angle of contact net, and guarantee slide 10 and the reliable contact of contact net by the pulling force that the extension spring produced.
As shown in fig. 2, the pantograph lifting assembly 2 can be connected to the pantograph head 1 and used to lift or lower the pantograph head 1. The pantograph assembly 2 may comprise a base frame 20, a hinge structure 21, a drive member 22, a current system detector and a controller, wherein:
the undercarriage 20 may be secured to the roof of the electric locomotive to provide a mounting base for the hinge structure 21 and the driver 22. The underframe 20 may be a frame structure formed by splicing edge beams, and of course, the underframe 20 may also be formed integrally, which is not limited herein.
It should be noted that, chassis 20's lateral part can be equipped with water conservancy diversion copper bar 200, because the pantograph of this application can contact and the current collection with the contact net of different standards, so need weld a plurality of cylinder manifold that are used for the wiring on this pantograph, nevertheless because electric locomotive needs very big operating current under direct current mode, in order to avoid the cylinder manifold to cause the intensification too high because of bearing too big operating current, can be at chassis 20's lateral part installation water conservancy diversion copper bar 200, and arrange the cable on water conservancy diversion copper bar 200, so, not only can satisfy the transmission of heavy current, and can open a hole at water conservancy diversion copper bar 200's optional position, and then make things convenient for the arranging of cable. In addition, the connecting part of the chassis 20 and the diversion copper bar 200 can be protected by adopting a conductive spraying agent, so that the connecting part is prevented from being corroded, and the temperature rise of the connecting part is reduced.
The hinge structure 21 may comprise an upper arm 211 and a lower arm 212, wherein: the upper arm 211 is connected to the head 1, the lower arm 212 is connected to the base frame 20, and the upper arm 211 and the lower arm 212 are rotatably connected, so that the head 1 can be raised or lowered when the upper arm 211 and the lower arm 212 rotate.
Because the current needs to be transmitted from the bow 1 to the underframe 20 through the hinge structure 21, but the upper arm 211 and the lower arm 212 of the hinge structure 21 are rotatably connected through the rotating shaft, the contact state is unstable, and in order to avoid the problem that the temperature rise is too high due to poor contact when a large current passes through the rotating shaft, the copper stranded wire 23 can be arranged between the upper arm 211 and the lower arm 212, the current can be transmitted from the copper stranded wire 23 avoiding the rotating shaft, and the specification and the number of the copper stranded wires 23 are not particularly limited here.
A drive 22 may be provided on the base frame 20 for driving the upper arm 211 and the lower arm 212 to rotate to control the raising or lowering of the bow 1. For example, the driving member 22 may include a valve plate 220, a pantograph device 221, and a gas pipe 222 connecting the valve plate 220 and the pantograph device 221, wherein: compressed gas generated by an air source system of the electric locomotive enters an air path in the pantograph device 221 through the valve plate 220 and the air pipe 222, the compressed gas in the air path can drive a guide disc of the pantograph device 221 to move, the guide disc pulls a steel wire rope, so that the steel wire rope wound on the guide disc drives the lower arm 212 to rotate, then the upper arm 211 is driven to rotate, and finally the pantograph head 1 is lifted or lowered.
Specifically, the valve plate 220 may include a direction switching valve, a first pressure regulating valve, a second pressure regulating valve, and a pressure switch, wherein:
the reversing valve may be communicated with the first pressure regulating valve or the second pressure regulating valve, and compressed gas generated by the wind source system of the electric locomotive may enter the gas path in the pantograph device 221 through the reversing valve and the first pressure regulating valve, at this time, the first pressure regulating valve may regulate the gas pressure in the gas path to a contact pressure (first pressure) in an alternating current mode; similarly, the compressed air generated by the wind source system of the electric locomotive may enter the air path of the pantograph device 221 through the reversing valve and the second pressure regulating valve, and at this time, the second pressure regulating valve may regulate the air pressure in the air path to the contact pressure (second pressure) in the direct current mode.
Therefore, the pantograph of the present application operates as follows: when the pantograph is lifted for the first time, the reversing valve is communicated with the first pressure regulating valve, and compressed gas supplies air to a gas circuit of the pantograph through the first pressure regulating valve, so that the sliding plate 10 is lifted and contacts with a contact net for current collection; subsequently, a current system detector is used for detecting the current system of the current overhead line system, and the current system detector is described in detail in the foregoing, and is not described again here; if the current system of the contact net is in an alternating current mode, the flow rate of the compressed gas passing through the valve plate 220 is kept unchanged, that is, the compressed gas is kept to supply air to the gas path in the pantograph device 221 through the first pressure regulating valve, so that the contact pressure (first pressure) between the sliding plate 10 and the contact net is kept unchanged; if the current system of the catenary is in a direct current mode, the valve plate 220 is controlled to increase the flow of the compressed gas, i.e., the reversing valve is switched and communicated with the second pressure regulating valve, so that the compressed gas supplies air to the gas path in the pantograph device 221 through the second pressure regulating valve, and the contact pressure between the sliding plate 10 and the catenary is a second pressure.
The controller of the embodiment of the present disclosure is connected to the current system detector, and after the current system detector detects the current system of the catenary and feeds back the result to the controller, the controller can control the pantograph head 1 to be raised or lowered according to the current system of the catenary, so as to adjust the contact pressure between the sliding plate 10 and the catenary. For example, the controller may be a single chip microcomputer disposed on the pantograph lifting assembly, and of course, may also be a central processing unit of the locomotive, which is not particularly limited herein.
The pressure switch in the valve plate 220 is a gas path switching indicating switch, when the compressed gas supplies air to the gas path in the pantograph device 221 through the first pressure regulating valve, the level signal output by the pressure switch is a low level signal, and when the compressed gas supplies air to the gas path in the pantograph device 221 through the second pressure regulating valve, the level signal output by the pressure switch is a high level signal.
At this time, the controller described above can also receive the level signal, and compare the level signal (low level signal/high level signal) with the current system (ac mode/dc mode) of the catenary to confirm that the contact pressure (first pressure/second pressure) corresponding to the level signal matches with the current system (ac mode/dc mode) of the catenary, that is, when the level signal matches with the current system, the controller can open the authority to the operator, so that the operator can start the electric locomotive.
Of course, the valve plate 220 may further include a first pressure gauge and a second pressure gauge, the first pressure gauge is used to display the pressure value of the compressed gas in the alternating current mode, and the second pressure gauge is used to display the pressure value of the compressed gas in the alternating current mode, so as to facilitate the measurement of the contact pressure by the operator. It should be noted that the valve plate 220 of the embodiment of the present disclosure may further include a safety valve, and when the pressure exceeds a set value of the safety valve due to a failure of the valve plate 220, the safety valve acts to prevent the gas path pressure from being too high to damage the pantograph 221.
There is also provided in an embodiment of the present disclosure an electric locomotive including a pantograph as claimed in any one of the above, which will not be described in detail herein.
