Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, and in particular to a manual discharge detection integrated device. Background Technology

[0002] In rail transit power supply systems, to ensure the safety of maintenance personnel, a contact network voltage test is usually performed before grounding wires are installed to confirm that there is no voltage in the contact network before work can proceed. In existing technology, separate voltage detectors and dischargers are typically used to perform the voltage detection and discharge operations separately. However, using separate voltage detectors and dischargers requires initial voltage detection; if residual voltage is detected, the discharger must be used to discharge it; after discharge, voltage detection must be performed again to ensure the contact network voltage drops below a safe level. This entire process is cumbersome and inefficient. Furthermore, since the voltage detector and discharger are two separate sets of equipment, they are inconvenient for on-site operators to carry, affecting the convenience of construction.

Preferably, the outer shell of the operation and display module 300 is wrapped with anti-slip rubber to enhance stability, and its bottom is provided with a connection end for connecting to the surface of the voltage detection pole 100.

[0034] This utility model's technical solution incorporates a discharge detection module 200 and an operation and display module 300 within a manual discharge detection integrated device. The discharge detection module 200 includes an integrated discharge detection circuit 210 and a discharge circuit 220. One end of the discharge detection module 200 is connected to the mounting part 120, and the other end is connected to the return rail 600 via a grounding cable 500. The discharge detection circuit 210 and the discharge circuit 220 are connected in parallel between the mounting part 120 and the grounding cable 500, forming a parallel circuit. This combines the discharge detection and discharge functions for integrated operation. Simultaneously, the discharge detection module 200 and the operation and display module 300 are wirelessly connected, allowing the operation and display module 300 to display the real-time energized and discharged status of the contact network 400, enabling operators to promptly understand the discharge and energized status of the contact network 400. The wireless communication between the discharge detection module 200 and the operation and display module 300 effectively isolates the high-voltage contact network 400 from the low-voltage operation and display module 300, while also reducing the need for cable connections. This utility model embodiment can facilitate the integration of voltage detection and discharge, reduce the number of times operators need to perform voltage detection and discharge operations, save operation time, is easy to carry, improve work efficiency, and enhance the convenience, safety, and intelligence level of the voltage detection and discharge process.

[0035] like Figure 2 As shown, the discharge detection module 200 also includes: a first control module 230. The voltage divider resistor 212 outputs a low-voltage signal to the first control module 230. The first control module 230 can collect the current voltage data of the contact network 400 to obtain the discharge detection result, and control the conduction state of the high-voltage relay 222 according to the discharge command. The first control module 230 can collect the current voltage of the contact network 400, control the on / off state of the high-voltage relay 222, and transmit the data to the operation and display module 300 in real time via wireless communication.

The discharge circuit 220 includes a discharge resistor 221 and a high-voltage relay 222. The high-voltage relay 222 is configured to conduct upon receiving a discharge command, allowing the discharge resistor 221 to release the residual voltage of the contact network 400. In one embodiment, the voltage detection circuit 210 includes two high-resistance resistors 211 connected in series, with the voltage divider resistor 212 connected in series between the two high-resistance resistors 211. This invention limits the voltage detection current by connecting at least two high-resistance resistors 211 in series in the voltage detection circuit 210, which helps ensure that the current in the voltage detection circuit 210 is in the microampere range, thus improving the safety of the operator. By setting the voltage divider resistor 212, the output is sent to the first control module 230 to calculate the voltage value of the contact network 400. The smaller the voltage divider resistor 212, the smaller the voltage.

[0038] like Figure 3As shown, the first control module 230 further includes a discharge module 231, which is electrically connected to the first control module 230 to discharge the residual voltage of the contact network 400. When the first control module 230 collects the current voltage data of the contact network 400 and it exceeds a preset threshold, the discharge trigger key 350 is pressed, and the first control module 230 controls the high-voltage relay 222 to turn on. The discharge module 231 is configured to connect the discharge resistor 221 to the discharge circuit 220 to perform the discharge operation of the residual voltage. When the first control module 230 collects the current voltage data of the contact network 400 and it drops below the preset threshold, the voltage detection trigger key 340 is pressed, and the first control module 230 controls the high-voltage relay 222 to turn off, terminating the discharge operation and performing the voltage detection operation. This utility model's technical solution uses a first control module 230 to collect the current voltage of the contact network 400, and controls the high-voltage relay 222 to turn on or off based on the discharge command transmitted to the first control module 230 via wireless communication through the voltage detection trigger key 340 and the discharge trigger key 350, as well as the collected voltage data, to perform the discharge operation.

The operator then lifts the rod and attaches the metal hook of the discharge detection module 200 to the contact wire 400. Finally, the operator presses the second power-on / off button 384 of the second power-on / off control module 380 of the operation and display module 300 to activate it and put it into working mode. Pressing the voltage detection trigger button 340 on the operation and display module 300 sends a voltage detection command to the discharge module 200 via the second Bluetooth communication unit 320 of the operation and display module 300. The first Bluetooth communication unit 240 of the discharge module 200 receives the voltage detection command, and the first control module 230 of the discharge module 200 returns the voltage detection result to the operation and display module 300 via a wireless transmission channel. At this time, the voltage value of the contact wire 400 will be displayed on the screen 330 of the operation and display module 300. If the residual voltage of the contact wire 400 is too high, pressing the discharge trigger button 350 on the operation and display module 300 sends a discharge command to the discharge module 200 via a wireless transmission channel. The first control module 230 of the discharge module 200 controls the high-voltage relay 222 in the discharge circuit 220 to conduct. The discharge resistor 221 in the discharge circuit 220 will generate heat and consume the residual voltage until the discharge is complete. After the discharge is completed, press the voltage detection trigger key 340 on the operation and display module 300 to transmit the voltage detection command to the discharge detection module 200 through the wireless transmission channel. The discharge detection module 200 continues the voltage detection process, and the voltage value of the contact network 400 after discharge will be displayed on the display screen 330.

[0053] This utility model integrates the voltage detection circuit 210 and the discharge circuit 220 into one, sharing a single electrical circuit. This facilitates integrated voltage detection and discharge, reducing the number of times operators need to perform voltage detection and discharge operations, saving operation time, and improving portability and work efficiency. The voltage detection / discharge module 200 and the operation and display module 300 communicate wirelessly, effectively isolating the high-voltage contact network 400 from the low-voltage operation and display module 300, while also reducing cable connections. The operation and display module 300 allows for real-time display of the contact network 400's energized and discharging status, enabling operators to promptly understand the voltage detection and discharging status of the contact network 400.
