Embodiment Construction
[0108] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0109] The composition of the device of the present invention and the mutual connection and communication such as figure 1 and figure 2 As shown, that is, in each substation, two DC traction protection measurement and control devices are placed on the single-row catenary. These two devices are connected to one double-sided jumper device and communicate with each other, but the two devices are not directly connected and communicated. Stations are connected and communicated through bilateral joint jump devices.
[0110] The specific values of U and I in the figure are shown in Table 1.
[0111] Table 1 is the present invention figure 1 Description of U and I in
[0112]
[0113] This device has two structures, respectively as figure 1 and figure 2 As shown, the configurations of these two devices are the same, but the information communica...

An urban rail transit catenary fault location device and method for large and small double-sided switching power supply, the device includes: on the uplink and downlink catenary in each substation, two DC traction protection measurement and control devices are equipped, and the same double-sided jumper device is respectively connected ; Two DC traction protection measurement and control devices are respectively connected to the shunts in the corresponding intervals through DC transmitters to collect current and the voltage of the catenary to the rail and ground; the DC transmitters on the uplink and downlink catenary at one end pass The first cable transmits the current information to the corresponding DC traction protection measurement and control device, the voltage information is transmitted to the corresponding DC traction protection measurement and control device through the second cable, and the current information is transmitted to the downstream terminal at the same end of the substation through the third cable. and the DC traction protection measurement and control device on the uplink catenary; the bilateral jumper devices between the substations are connected to each other. The invention can reduce the cost, shorten the failure time, reduce the impact on driving and improve the efficiency.
Description
technical field [0001] The invention relates to a fault location device for an urban rail transit catenary with large and small bilateral switching power supply. The invention also relates to a method for locating faults in urban rail transit catenary with large and small bilateral switching power supply. Background technique [0002] Now, the subway power supply system is no longer a single-ended power supply method or a simple double-ended power supply method, but a double-ended power supply method with bilateral switching between large and small, and its power supply system becomes correspondingly complicated. When the power supply system fails, it is very difficult to find the fault quickly and accurately. [0003] Existing technology is exactly after breakdown takes place, goes to spot detection by manpower. In this way, a huge cost of manpower and material resources is required, and the time of fault discovery is unpredictable, which has a huge impact on driving and ...
