Description

Technical Field

[0001] This utility model relates to the field of circuit testing technology, specifically to an AC turnout operation test instrument. Background Technology

[0002] Currently, there are no specialized instruments for testing turnout circuits, either domestically or internationally. Testing and recording rely on multimeters, which is a limited testing method. It can only test wiring and cannot comprehensively test the starting circuit, the operating current and voltage of the indicator circuit, the operating time, and other operational aspects. During on-site overhauls and turnout replacements, inadequate operational testing often leads to turnout equipment failing to operate normally. When commissioning AC turnouts during construction and installation, bulky generators are typically used as the operating power source. A simple, homemade manual wiring device is then used to operate the turnout for position and reverse tests. This method is prone to errors and damage to equipment, has low testing accuracy, poses safety hazards, is labor-intensive, and results in low overall construction efficiency.

[0003] Based on the above situation, there is an urgent need for an AC turnout operation test instrument to solve the problem of inconvenience in testing AC turnouts. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing turnout testing methods are inconvenient for comprehensively testing the starting circuit, indicator circuit operating current, operating voltage, operating time, and operating status of AC turnouts, thus solving the problem of inconvenient testing of AC turnouts.

[0005] The technical solution of this utility model is as follows:

[0006] The AC turnout operation test instrument includes:

[0007] The power module is used for power supply;

[0008] An inverter module is electrically connected to the power module and is used to invert DC voltage into AC voltage.

[0009] Control module; electrically connected to the inverter module;

[0010] The acquisition module is electrically connected to the control module. The acquisition module includes five voltage acquisition channels and five current acquisition channels. Each voltage acquisition channel and current acquisition channel is connected to an acquisition probe. The five voltage acquisition channels acquire three phase voltages, the indicated voltage, and the output voltage, respectively. The five current acquisition channels acquire three phase currents, the indicated current, and the output current, respectively.

[0011] Existing turnout testing methods are inconvenient for comprehensively testing the starting circuit, indicator circuit operating current, operating voltage, operating time, and operating status of AC turnouts. In this solution, the power module replaces the generator to drive the AC switch machine, enabling the tester to operate continuously for extended periods. Five voltage acquisition channels collect three phase voltages, indicator voltages, and output voltages respectively, and five current acquisition channels collect three phase currents, indicator currents, and output currents respectively, forming a three-phase five-wire system. The control module checks the wiring of this three-phase five-wire turnout to ensure the tester functions properly, thereby monitoring different turnout positions such as positioning, reverse, and four-way opening, thus solving the problem of inconvenient testing of AC turnouts.

[0012] Furthermore, in order to ensure the phased speed requirements during the turnout switching process, one feasible solution is to install a frequency converter between the inverter module and the control module. When this solution is adopted, the frequency converter can adjust the frequency and voltage of the power supply module to precisely control the speed of the switch machine motor, thereby ensuring the phased speed requirements during the turnout switching process.

[0013] Furthermore, this solution does not exclusively limit the specific structure of the control module. One feasible solution is that the control module includes a processor and a control unit electrically connected to the processor, and the frequency converter is electrically connected to the control unit. When this solution is adopted, the control unit receives the electrical signal from the frequency converter, and then adjusts the output voltage and output current.

[0014] Furthermore, to facilitate the display of changes in three-phase voltage and / or three-phase current during the test, one feasible solution is that the processor is connected to a display module. When this solution is adopted, the display module can display the changes in three-phase voltage and / or three-phase current during the test, so as to facilitate the monitoring of three-phase voltage and / or three-phase current.

[0015] Furthermore, to facilitate switching of working states, one feasible solution is that the processor is connected to a button module. When this solution is adopted, the button module facilitates the execution of fixed operation actions, the execution of reverse operation actions, or the emergency stop of the equipment.

[0016] Furthermore, to facilitate the overall switching of this tester, one feasible solution is that the button module includes a circuit breaker. When this solution is adopted, the overall machine can be switched on and off through the circuit breaker, avoiding cumbersome operations.

[0017] Furthermore, the acquisition probe includes a fixed arm and a movable arm rotatably connected to the fixed arm. A spring is installed between the fixed arm and the movable arm. Several limit screws are installed on both the fixed arm and the movable arm. The limit screws are connected to insulated knobs. By rotating the insulated knobs, the position of the limit screws is adjusted, thereby adjusting the wire to be tested to the center of the acquisition probe. This makes it suitable for wires of different sizes and improves the acquisition accuracy.

[0018] Furthermore, both the fixed arm and the movable arm have insulating sleeves that mate with the insulating knobs, and the insulating knobs extend into the insulating sleeves.

[0019] Compared with existing technologies, the beneficial effects of this utility model are:

[0020] 1. By replacing the generator with the power module to drive the AC switch machine, this tester can be used continuously for a long time. It collects three phase voltages, the indicated voltage, and the output voltage through five voltage acquisition channels, and collects three phase currents, the indicated current, and the output current through five current acquisition channels, which is a three-phase five-wire system. The control module checks the wiring of the three-phase five-wire turnout to ensure that the tester works normally. It can then monitor different positions of the turnout, such as the positioning, reverse position, and four-way opening, solving the problem of the inconvenience of testing AC turnouts.

[0021] Second, since a frequency converter is installed between the inverter module and the control module, the frequency and voltage of the power supply module can be adjusted through the frequency converter to precisely control the speed of the switch machine motor, thereby ensuring the phased speed requirements of the turnout switching process.

[0022] Third, since the control module includes a processor and a control unit electrically connected to the processor, the frequency converter is electrically connected to the control unit, and receives electrical signals from the frequency converter through the control unit, thereby adjusting the output voltage and output current.

[0040] Existing turnout testing methods are inconvenient for comprehensively testing the starting circuit, indicator circuit operating current, operating voltage, operating time, and operating status of AC turnouts. In this solution, the power module replaces the generator to drive the AC switch machine, enabling the tester to operate continuously for extended periods. Five voltage acquisition channels collect three-phase voltages, indicator voltages, and output voltages respectively, while three-phase currents, indicator currents, and output currents are collected through a current acquisition channel, forming a three-phase five-wire system. The control module checks the wiring of this three-phase five-wire turnout to ensure the tester functions properly, thereby monitoring different turnout positions such as positioning, reverse, and four-way opening, thus solving the problem of inconvenient testing of AC turnouts.

[0041] Optionally, the power module also includes a 220V power supply interface to facilitate the use of an external power source when the power storage is low.

[0042] To ensure the phased speed requirements during the turnout switching process, one feasible solution is to install a frequency converter between the inverter module 1 and the control module 2. With this solution, the frequency converter can adjust the frequency and voltage of the power supply module to precisely control the speed of the switch machine motor, thereby ensuring the phased speed requirements during the turnout switching process.

[0046] To facilitate the overall switching of this tester, one feasible solution is that the button module 4 includes a circuit breaker. When this solution is adopted, the overall machine can be switched on and off through the circuit breaker, avoiding cumbersome operations.

[0047] Reference Figure 3This solution does not limit the specific structure of the acquisition probe. One feasible solution is as follows: The acquisition probe includes a fixed arm 31 and a movable arm 32 rotatably connected to the fixed arm 31. A spring 33 is installed between the fixed arm 31 and the movable arm 32. Several limiting screws 34 are installed on both the fixed arm 31 and the movable arm 32. The limiting screws 34 are connected to an insulating knob 35. When using this solution, the position of the limiting screws 34 is adjusted by rotating the insulating knob 35, thereby adjusting the wire to be tested to the middle of the acquisition probe. This solution is applicable to wires of different sizes and improves the acquisition accuracy.

[0048] Preferably, in this embodiment, both the fixed arm 31 and the movable arm 32 are provided with insulating sleeves 36 that cooperate with the insulating knob 35, and the insulating knob 35 extends into the insulating sleeve 36. When this solution is adopted, the cooperation between the insulating sleeve 35 and the insulating knob 35 can ensure the safety of rotating the insulating knob 35 and avoid electric shock.

[0049] To address the inconvenience of testing AC turnouts, this solution replaces the generator with a power module to drive the AC switch machine, enabling the tester to operate continuously for extended periods. Five voltage acquisition channels collect three phase voltages, the indicated voltage, and the output voltage; five current acquisition channels collect three phase currents, the indicated current, and the output current, forming a three-phase five-wire system. The control module checks the wiring of this three-phase five-wire turnout system to ensure the tester functions correctly, thereby monitoring different turnout positions such as positioning, reverse, and four-way opening, thus resolving the problem of inconvenience in testing AC turnouts.
