[0020] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0021] The following describes a method and device for monitoring the operating status of a circuit breaker energy storage oil pump according to an embodiment of the present application with reference to the accompanying drawings.

[0022] Figure 1 It is a flow chart of a method for monitoring the operating status of a circuit breaker energy storage oil pump provided in an embodiment of the present application.

[0023] like Figure 1 As shown, the method may include but is not limited to the following steps:

[0024] Step S101: Obtain a circuit breaker control signal.

[0025] In an embodiment of the present application, the circuit breaker control signal includes at least one of the following: a closing position signal; an opening position signal; a closing position reset signal; and an opening position reset signal.

[0026] Step S102: Based on the circuit breaker control signal, determine a target trigger condition from a plurality of preset trigger conditions.

[0027] Among them, in an embodiment of the present application, the preset multiple trigger conditions include: the closing position signal is valid and the opening position reset signal is valid; the opening position signal is valid and the closing position reset signal is valid; the closing position signal is valid; the opening position signal is valid.

[0028] For example, taking the first trigger condition being that the closing position signal is valid; the second trigger condition being that the opening position signal is valid; the third trigger condition being that the closing position signal is valid and the opening position reset signal is valid; and the fourth trigger condition being that the opening position signal is valid and the closing position reset signal is valid as an example, if it is determined that only the closing position signal is valid, the first trigger condition is used as the target trigger condition; if it is determined that only the opening position signal is valid, the second trigger condition is used as the target trigger condition; if it is determined that the closing position signal is valid and the opening position reset signal is valid, the third trigger condition is used as the target trigger condition; if it is determined that the opening position signal is valid and the closing position reset signal is valid, the fourth trigger condition is used as the target trigger condition.

[0029] Step S103: Obtain the duration threshold corresponding to the target trigger condition.

[0030] Exemplarily, corresponding duration thresholds are set in advance for different trigger conditions, thereby obtaining the duration threshold corresponding to the target trigger condition.

[0031] It should be noted that, in the embodiments of the present application, the duration thresholds corresponding to different trigger conditions may be the same or different.

[0032] For example, taking the trigger condition that the closing position signal is valid as an example, the corresponding time threshold may be 10 seconds.

[0033] For example, taking the trigger condition as the validity of the trip position signal, the corresponding time threshold may be 10 seconds.

[0034] For example, taking the trigger condition that the closing position signal is valid and the opening position reset signal is valid as an example, the corresponding time threshold may be 20 seconds.

[0035] For example, taking the trigger condition that the opening position signal is valid and the closing position reset signal is valid as an example, the corresponding time threshold may be 30 seconds.

[0036] It should be noted that, in the embodiment of the present application, a corresponding time threshold may be set according to the time required for the circuit breaker energy storage oil pump to complete pressure building to the rated pressure in each operating state.

[0037] For example, if the oil pump runs and builds up the pressure to the rated pressure after the power plant switch is closed, it takes approximately 8-15 seconds; if the oil pump runs and builds up the pressure to the rated pressure after the 500kV switch is opened, it takes approximately 18-25 seconds; and if the oil pump runs and builds up the pressure to the rated pressure when the 500kV switch is in operation or opened, it takes approximately 2-6 seconds. The alarm value for the oil pump running time after the 500kV switch is closed is defined as Ta1, the alarm value for the oil pump running time after the 500kV switch is opened is defined as Ta2, the alarm value for the oil pump running and maintaining pressure when the 500kV switch is in operation is defined as Ta3, and the alarm value for the oil pump running and maintaining pressure when the 500kV switch is opened is defined as Ta4. Considering that signal transmission may occasionally be delayed during the pressure building process, in order to avoid frequent false alarms, the alarm value of Ta1 is set to 20 seconds, the alarm value of Ta2 is set to 30 seconds, and the alarm values of Ta3 and Ta4 are set to 10 seconds. That is, Ta1=20s, Ta2=30s, Ta3=10s, Ta4=10s.

[0038] Step S104: determining whether the circuit breaker energy storage oil pump is in the automatic position, and obtaining the operating time of the circuit breaker energy storage oil pump in the current operating state.

[0039] Exemplarily, timing is started when a circuit breaker oil pump operation signal is obtained to obtain the operation time of the circuit breaker energy storage oil pump in the current operation state.

[0040] In some embodiments, an oil pump automatic position status signal may be acquired to determine whether the oil pump is in the automatic position according to the oil pump automatic position status signal.

[0041] Step S104: determining whether the circuit breaker energy storage oil pump is in the automatic position, and obtaining the operating time of the circuit breaker energy storage oil pump in the current operating state.

[0042] Exemplarily, it is determined that the circuit breaker energy storage oil pump is in the automatic position, and timing is started after the circuit breaker oil pump operation signal is obtained, which is used as the operation time of the circuit breaker energy storage oil pump in the current operation state.

[0043] It should be noted that, in the embodiments of the present application, each operating state corresponds to a trigger condition.

[0044] Step S104: Based on the time threshold and the operation time, monitor whether the circuit breaker energy storage oil pump operates normally.

[0045] For example, when the running time of the oil pump is greater than or equal to the time threshold corresponding to the target trigger condition, it is determined that there is an abnormality in the operation of the oil pump and an alarm is issued.

[0046] For example, if the circuit breaker satisfies the conditions that the closed position signal is valid and the open position reset signal is valid, the running time of the oil pump is started to be measured when the circuit breaker oil pump running signal is received. When the running time of the oil pump is greater than or equal to the corresponding time threshold, it is reported that the running time of the circuit breaker oil pump is too long and the oil pump efficiency is low.

[0047] For example, if the circuit breaker satisfies the conditions that the open position signal is valid and the closed position reset signal is valid, the running time of the oil pump is started to be measured when the circuit breaker oil pump running signal is received. When the running time of the oil pump is greater than or equal to the corresponding time threshold, it is reported that the running time of the circuit breaker oil pump is too long and the oil pump efficiency is low.

[0048] For example, if the circuit breaker meets the requirement that the closing position signal is valid, the oil pump operation time is counted when the circuit breaker oil pump operation signal is received. When the oil pump operation time is greater than or equal to the corresponding time threshold, it is reported that the circuit breaker oil pump operation time is too long and the oil pump efficiency is low.

[0049] For example, if the circuit breaker satisfies the open position signal validity, the oil pump operation time is counted when the circuit breaker oil pump operation signal is received. When the oil pump operation time is greater than or equal to the corresponding time threshold, it is reported that the circuit breaker oil pump operation time is too long and the oil pump efficiency is low.

[0050] By implementing the embodiments of the present application, a target trigger condition can be determined from multiple preset trigger conditions based on the validity of the circuit breaker control signal to obtain a duration threshold corresponding to the target trigger condition. Thus, when the oil pump is in the automatic position, the normal operation of the oil pump can be monitored based on the duration threshold and the oil pump's operating time. This allows for rapid and accurate monitoring of the operating status of the circuit breaker energy storage oil pump.

[0051] See Figure 2 , Figure 2 Schematic diagram of a monitoring device for the operating status of a circuit breaker energy storage oil pump provided in an embodiment of the present application. Figure 2 As shown, the device 200 includes: an acquisition module 201, which is used to obtain a circuit breaker control signal; a first processing module 202, which is used to determine a target trigger condition from a plurality of preset trigger conditions based on the circuit breaker control signal; a second processing module 203, which is used to obtain a duration threshold corresponding to the target trigger condition; a third processing module 204, which is used to determine whether the circuit breaker energy storage oil pump is in the automatic position and obtain the operating time of the circuit breaker energy storage oil pump in the current operating state; a monitoring module 205, which is used to monitor whether the circuit breaker energy storage oil pump is operating normally based on the duration threshold and the operating time.

[0052] In one implementation, the circuit breaker control signal includes at least one of the following: a closing position signal; an opening position signal; a closing position reset signal; and an opening position reset signal.

[0053] In an optional implementation, the trigger condition includes at least one of the following: the closing position signal is valid; the opening position signal is valid; the closing position signal is valid and the opening position reset signal is valid; the opening position signal is valid and the closing position reset signal is valid.

[0054] The device of the embodiment of the present application can determine a target trigger condition from multiple preset trigger conditions based on the validity of the circuit breaker control signal, and obtain a duration threshold corresponding to the target trigger condition. When the oil pump is in the automatic position, the device can monitor whether the oil pump is operating normally based on the duration threshold and the oil pump's operating time. This allows for rapid and accurate monitoring of the operating status of the circuit breaker's energy storage oil pump.
