It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
An embodiment of the present invention provides a feeder automation terminal tester, and fig. 1 is a schematic structural diagram of the feeder automation terminal tester provided in the embodiment of the present invention, referring to fig. 1, where:
the analog circuit breaker 12 is used for being connected with a feeder automation terminal 20 to be tested;
and the controller 11 is configured to acquire an operation parameter of the analog circuit breaker 12, and determine that the feeder automation terminal 20 to be tested is abnormal when the operation parameter of the analog circuit breaker 12 is different from the standard parameter.
The analog circuit breaker 12 may be any device capable of simulating the operating characteristics of the circuit breaker, and the specific configuration or model of the analog circuit breaker is not limited in the embodiments of the present invention. The power transmission end of the analog circuit breaker 12 and the operation parameter acquisition end of the controller 11 are both connected to the wire end connected with the original circuit breaker. The analog circuit breaker 12 may be connected to the feeder automation terminal 20 to be tested through a communication cable, so as to transmit a control signal sent by the feeder automation terminal 20 to be tested to the analog circuit breaker 12. The simulation circuit breaker 12 performs tripping and closing actions according to the received control signal, when the simulation circuit breaker 12 acts, the controller 11 compares the operation parameters with the standard parameters, and if the operation parameters are the same as the standard parameters or the operation parameters meet the parameter range of the standard parameters, the feeder automation terminal 20 to be tested is judged to act normally; and if the operation parameters are different from the standard parameters or the operation parameters do not conform to the parameter range of the standard parameters, judging that the action of the feeder automation terminal 20 to be tested is abnormal. Wherein the operating parameter can be any parameter related to the operating state of the analog circuit breaker 12. Illustratively, the operating parameters include the voltage across the simulated circuit breaker 12 and the time to loss of power on either side of the simulated circuit breaker 12. Alternatively, the operating parameters include the voltage across the simulated circuit breaker 12 and the current of the simulated circuit breaker 12. The standard parameter is an operation parameter of the corresponding simulated circuit breaker 12 when the feeder automation terminal 20 to be tested should send a control signal to control the circuit breaker to open or close. The values of the standard parameters may be determined according to the specific model or the specific control logic of the actual feeder automation terminal 20 to be tested.
Illustratively, the communication cable may be a 4-core air wire, since the 4-core air wire integrates 4 wires into 1 cable, and a standardized interface is adopted. Therefore, the convenience of connection and disconnection of the communication cable is further improved, and the testing efficiency is further improved.
Fig. 2 is another schematic structural diagram of a feeder automation terminal tester according to an embodiment of the present invention, and referring to fig. 2, in other embodiments, the feeder automation terminal tester 10 further includes a voltage provider 13, and the voltage provider 13 is connected to the analog circuit breaker 12 and the controller 11, respectively.
The voltage supplier 13 is configured to supply a test voltage to the power transmission terminal of the analog circuit breaker 12 and the operation parameter acquiring terminal of the controller 11. Therefore, the test can be completed without connecting the wire end connected with the original circuit breaker, wiring is simplified, the voltage provider 13 can also output controllable test voltage under the control of the controller 11, the change rate of the test voltage is far higher than that of the voltage in the actual operation environment, the test time is saved, and the test efficiency is greatly improved.
In other embodiments, the controller 11 is further configured to perform the following actions for a target number of times: acquiring the operation parameters of the simulated circuit breaker 12, and judging whether the operation parameters of the simulated circuit breaker 12 are the same as the standard parameters;
when the operating parameters of the analog circuit breaker 12 are different from the standard parameters, the controller 11 determines that the feeder automation terminal 20 to be tested is abnormal in action.
The target times can be set according to actual needs. The controller 11 may obtain the operation parameters and compare the operation parameters with the standard parameters when simulating the operation of the circuit breaker 12, repeat the operation for a target number of times, and determine whether the feeder automation terminal 20 to be tested is abnormal. The logic of determining whether the feeder automation terminal 20 to be tested is abnormal may be that, if the operation parameters of the target times all meet the standard parameters, the feeder automation terminal 20 to be tested is determined to be normal; and if the operation parameters of any one time in the target times do not meet the standard parameters, judging that the feeder automation terminal 20 to be tested is abnormal.
In other embodiments, the feeder automation terminal tester further includes a display (not shown) for displaying standard parameters as well as operating parameters of the simulated circuit breaker 12.
The display may be a device capable of displaying information, such as a nixie tube or a dot matrix screen, and the embodiment of the present invention is not limited to a specific type of the display. Displaying the standard parameters and the operating parameters of the mock circuit breaker 12 via the display enables the tester to have a clear understanding of the current state of the feeder automation terminal tester.
In other embodiments, the feeder automation terminal tester further comprises an input device (not shown) for inputting the standard parameters to the controller 11.
The input device may be a device for inputting information, such as a keyboard or a mouse, and the embodiment of the present invention is not limited to a specific type of the input device. The standard parameters are input through the input device, so that a tester can quickly and conveniently modify the standard parameters to adapt to the feeder automation terminals 20 to be tested with different models, and the compatibility of the feeder automation terminal tester is enhanced.
In other embodiments, the display is multiplexed as an input device, the display comprising a touch screen.
The tester can modify the standard parameters in a touch screen mode. The touch screen is also capable of displaying standard parameters as well as operating parameters of the simulated circuit breaker 12. The display is reused as the input device, so that the structure of the feeder automation terminal tester can be simplified, the volume of the feeder automation terminal tester is reduced, and the feeder automation terminal tester is convenient to carry. And standard parameters are modified on the screen in a touch manner, so that the method is simpler and more intuitive, and the user friendliness of human-computer interaction is stronger.
In other embodiments, the feeder automation terminal tester further comprises an indicator (not shown) for indicating whether the feeder automation terminal under test is normal.
The indicator may be a sounding alarm, a light-emitting alarm, an audible and visual alarm, or other devices having a prompting function, or may be a designated area of a display, and the embodiment of the present invention is not limited to specific types thereof. When the feeder automation terminal tester detects that the action of the feeder automation terminal 20 to be tested is abnormal, an alarm can be given through the indicator. Illustratively, when the feeder automation terminal tester detects that the feeder automation terminal 20 under test is abnormally operated, the controller 11 controls the light emitting diode as the indicator to emit light. Thereby reminding the tester of the abnormal operation of the feeder automation terminal 20 to be tested. According to the embodiment of the invention, the indicator is used for reminding the tester, so that the test result can be more visually embodied, and the accuracy of reading the test result by the tester is improved.
In other embodiments, the controller 11 comprises a single-chip microcomputer.
