[0052] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with Figures 1-7.

[0053] The present application embodiment provides a plum blossom moving contact multi-parameter fusion sensor, referring to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the plum blossom moving contact multi-parameter fusion sensor includes a housing 11, and the housing 11 is sleeved on the plum blossom moving contact of the trolley circuit breaker to monitor various states of the plum blossom moving contact.

[0054] The plum blossom moving contact multi-parameter fusion sensor also includes a pressure detection sensor 12 , a laser array detection sensor 13 , a temperature detection sensor 14 and a CT power supply module 15 .

[0055] The pressure detection sensor 12 can be provided with multiple or one. When the pressure detection sensor 12 is provided with multiple, the average value is taken as the measurement value. The pressure detection sensor 12 is mounted on the housing 11, and the pressure detection sensor 12 can contact the outer side of the spring contact finger on the plum blossom moving contact. When the plum blossom moving contact of the trolley circuit breaker is inserted into the static contact, the spring contact finger is deformed, so that after the spring contact finger is deformed, the pressure detection sensor 12 can detect the clamping force detection value of the plum blossom moving contact of the trolley circuit breaker on the static contact.

[0056] The laser array detection sensor 13 is installed in the housing 11. The laser array detection sensor 13 emits laser. After the plum blossom moving contact of the trolley circuit breaker is inserted into the static contact, the laser array detection sensor 13 detects the insertion depth detection value of the plum blossom moving contact of the trolley circuit breaker into the static contact by detecting multiple beams of laser reflected from the static contact.

[0057] The temperature detection sensor 14 is installed in the housing 11 to detect the temperature detection value on the plum blossom moving contact.

[0058] The CT power supply module 15 is fixed on the housing 11 . When current flows through the plum blossom moving contact, the CT power supply module 15 obtains electrical energy and supplies power to the pressure detection sensor 12 , the laser array detection sensor 13 and the temperature detection sensor 14 after passing through the power supply stabilization module.

[0059] A multi-parameter fusion sensor 1 for plum blossom moving contact provided in the present application monitors the connection status between the static contact and the plum blossom moving contact of the manual circuit breaker in real time through a pressure detection sensor 12, a laser array detection sensor 13, and a temperature detection sensor 14, so as to timely detect problems such as low connection strength between the static contact and the plum blossom moving contact, shallow insertion depth of the static contact, and excessive temperature of the plum blossom moving contact. And before the above problems can be caused, through early intervention, such as reloading, maintenance, cooling, etc., the impact on the operating status of the power system caused by the poor connection status between the static contact and the plum blossom moving contact is reduced.

[0060] A method for analyzing information feedback of a multi-parameter fusion sensor of a plum blossom moving contact is also provided in an embodiment of the present application. The method can be applied to a multi-parameter fusion sensor information feedback analysis system of a plum blossom moving contact. The executor of the method can be a main controller in the analysis system, and can be assisted by multiple sensors in the multi-parameter fusion sensor 1.

[0061] The following will be combined with specific implementation methods. Figure 5 The processing flow shown is described in detail, and the content can be as follows:

[0062] S101, receiving the current plum blossom moving contact state information fed back by the plum blossom moving contact multi-parameter fusion sensor 1.

[0063] In implementation, the multi-parameter fusion sensor 1 at least includes a pressure detection sensor 12 , a laser array detection sensor 13 and a temperature detection sensor 14 .

[0064] The main controller receives in real time the plum blossom moving contact status information fed back by the pressure detection sensor 12, the laser array detection sensor 13 and the temperature detection sensor 14. The plum blossom moving contact status information here includes the clamping force detection value of the static contact, the insertion depth detection value of the static contact and the temperature detection value of the plum blossom moving contact.

[0065] The main controller refers to the currently received plum blossom moving contact state information as current plum blossom moving contact state information, and refers to the previously received multiple plum blossom moving contact state information as historical plum blossom moving contact state information.

[0066] S102, generating current state warning information according to current plum blossom moving contact state information and a plurality of preset state thresholds.

[0067] In implementation, a plurality of state thresholds are preset in the main controller, and the plurality of state thresholds include a clamping force threshold, an insertion depth threshold, and a temperature threshold.

[0068] The main controller compares the clamping force detection value, the insertion depth detection value, and the temperature detection value in the current plum blossom moving contact state information with the clamping force threshold, the insertion depth threshold, and the temperature threshold, respectively.

[0069] If the clamping force detection value is less than the clamping force threshold, a current state warning message is generated indicating that the connection strength is weak; if the clamping force detection value is greater than or equal to the clamping force threshold, a current state warning message is generated indicating that the connection strength is normal.

[0070] If the insertion depth detection value is less than the insertion depth threshold, a current state warning message is generated indicating that the static contact insertion depth is shallow; if the insertion depth detection value is greater than or equal to the insertion depth threshold, a current state warning message is generated indicating that the static contact insertion depth is normal.

[0071] If the temperature detection value is less than the temperature threshold, a current state warning message carrying controllable temperature operation is generated; if the temperature detection value is greater than or equal to the temperature threshold, a current state warning message carrying a high temperature alarm is generated.

[0072] S103, receiving the plum blossom moving contact size information input by the user, and establishing a plum blossom moving contact dynamic simulation model at the connection between the trolley circuit breaker and the static contact according to the historical plum blossom moving contact state information, current state warning information and plum blossom moving contact size information fed back by the multi-parameter fusion sensor 1.

[0073] In the implementation, the main controller receives the size information of the plum blossom moving contact input by the user, so that the main controller can establish the simulation structure of the plum blossom moving contact. Then the main controller combines the historical plum blossom moving contact state information and the current plum blossom moving contact state information fed back by the multi-parameter fusion sensor 1 to build a preliminary plum blossom moving contact dynamic simulation model.

[0074] Furthermore, in order to facilitate the staff to timely understand the connection status of the plum blossom moving contact and the static contact, a status list is added to the dynamic simulation model of the plum blossom moving contact with the current status warning information, so that the staff can understand the status of the plum blossom moving contact in real time and dynamically through the simulation model of the plum blossom moving contact.

[0075] Optionally, after step S103, there is also the following Figure 6 The specific operation process is as follows:

[0076] S201, capturing clamping amount change information of the clamping force detection value and connection amount change information of the insertion depth detection value according to the dynamic simulation model of the plum blossom movable contact.

[0077] In implementation, the main controller captures the current clamping force detection value and multiple historical clamping force detection values, as well as the current insertion depth detection value and multiple historical insertion depth detection values ​​with the historical plum blossom moving contact state information and the current plum blossom moving contact state information in the plum blossom moving contact dynamic simulation model.

[0078] Then, a clamping force detection value variation curve graph is drawn using the current clamping force detection value and a plurality of historical clamping force detection values, and the drawn clamping force detection value variation curve graph is called clamping amount variation information.

[0079] At the same time, a change curve of the insertion depth detection value is drawn through the current insertion depth detection value and a plurality of historical insertion depth detection values, and the drawn change curve of the insertion depth detection value is called connection amount change information.

[0080] S202, calculating and generating a unit clamping change amount and a unit connection change amount according to the clamping change amount information and the connection change amount information.

[0081] In implementation, a sampling duration and a unit duration are preset in the main controller, where the sampling duration may be 1 week, 1 month, etc., and the unit duration may be 1 day, 1 hour, etc.

[0082] The main controller obtains the clamping force detection value change amount and the insertion depth detection value change amount within the sampling time before the current moment from the clamping amount change information and the connection amount change information. Then the unit amount is calculated by dividing the sampling time by the unit time. For example, there are 7 days in a week. Then the unit amount is divided by the clamping force detection value change amount and the insertion depth detection value change amount, respectively, to calculate the unit clamping change amount and the unit connection change amount.

[0083] S203, calculating and generating an estimated adjustment repair time according to the unit clamping change amount, the unit connection change amount and a plurality of state thresholds.

[0084] In implementation, the main controller uses multiple state thresholds and current clamping force detection values ​​and current insertion depth detection values ​​to respectively detect the difference in clamping force and the difference in insertion depth.

[0085] Then, the difference in clamping force and the difference in insertion depth are divided by the unit clamping change rate and the unit connection change, respectively, to calculate two adjustment times, and the smaller one of the two adjustment times is selected as the estimated adjustment repair time.

[0086] Optionally, in step S203, there is also the following processing, and the specific operation flow is as follows:

[0087] Generate a first safety margin corresponding to a clamping force detection value and a second safety margin corresponding to an insertion depth detection value according to current plum blossom movable contact state information and a plurality of state thresholds;

[0088] Calculate and generate a first estimated safety duration and a second estimated safety duration according to the first safety margin, the second safety margin, the unit clamping change, and the unit connection change;

[0089] An estimated adjustment and repair time is generated based on the first estimated safety time, the second estimated safety time and a preset adjustment time threshold.

[0090] In implementation, the main controller subtracts the clamping force threshold and the insertion depth threshold in multiple state thresholds from the current clamping force detection value and the current insertion depth detection value in the current plum blossom moving contact state information, respectively, to generate a first safety margin corresponding to the clamping force detection value and a second safety margin corresponding to the insertion depth detection value.

[0091] Then the main controller divides the first safety margin and the second safety margin by the unit clamping change and the unit connection change, respectively, to generate a first estimated safety time and a second estimated safety time.

[0092] The main controller further compares the first estimated safety time, the second estimated safety time and a preset adjustment time threshold, and selects the smallest time among the above three as the estimated adjustment repair time.

[0093] Optionally, in this application, there is also Figure 7 The specific operation process is as follows:

[0094] S301, obtaining the current flowing at the connection between the trolley circuit breaker and the static contact in real time, and generating a plurality of historical unit power consumptions according to a preset unit time and a plurality of historical current flows.

[0095] In implementation, a current transformer is also installed on the multi-parameter fusion sensor 1 to collect the current flowing at the connection between the trolley circuit breaker and the static contact.

[0096] The main controller receives the circulating current feedback from the current transformer in real time, and collects multiple historical circulating currents within the sampling period before the current moment. Furthermore, the sampling period before the current moment is divided into multiple unit nodes by unit time, and the rated circulating voltage value and multiple historical circulating currents are used to calculate the average historical unit power consumption in each unit node.

[0097] S302, using a preset self-check cycle and a plurality of historical unit power consumptions, generate an estimated peak power consumption corresponding to a plurality of unit durations within a preset estimated duration after the current moment.

[0098] In implementation, a self-check cycle period is preset in the main controller, and the main controller periodically performs state estimation in the self-check cycle period.

[0099] Specifically, the main controller is preset with an estimated duration, and the main controller selects a time period corresponding to the estimated duration after the current moment in multiple historical self-circulation cycles. Then, multiple historical unit power consumptions corresponding to the time period are captured, and the peak value of the multiple historical unit power consumptions corresponding to each unit duration in the estimated duration is selected. Here, the peak value of the multiple historical unit power consumptions corresponding to each unit duration is called the estimated peak power consumption.

[0100] S303: Generate temperature rise status information within a current estimated time period according to a plurality of estimated peak power consumptions.

[0101] During implementation, the main controller compares multiple estimated peak power consumptions with preset heating power thresholds to determine the estimated duration of heating required after the current moment, thereby facilitating the generation of temperature rise status information within the current estimated duration.

[0102] Optionally, in step S302, there is also the following processing, and the specific operation flow is as follows:

[0103] In a plurality of historical self-checking cycles, a plurality of target historical unit power consumptions corresponding to an estimated time period after a current moment are captured;

[0104] From multiple target historical unit power consumptions, the estimated peak power consumptions corresponding to peak values ​​of multiple unit durations within the estimated duration are screened out.

[0105] In implementation, the main controller captures multiple historical power consumptions corresponding to the estimated duration after the current moment in multiple historical self-checking cycles. For example, if the self-checking cycle is 1 week, and the estimated duration after the current moment is from 1:00 p.m. to 3:00 p.m. on Tuesday, then the historical unit power consumptions from 1:00 p.m. to 3:00 p.m. on Tuesdays for multiple weeks before the current week are obtained, and the filtered historical power consumptions are called target historical power consumptions. If the unit duration is 1 hour here, there can be multiple target historical power consumptions corresponding to each hour.

[0106] The main controller then filters out the peak value among the multiple target historical unit power consumptions corresponding to each unit time within the estimated time after the current moment from the multiple target historical unit power consumptions, and calls the peak value among the multiple target historical unit power consumptions corresponding to each unit time estimated peak power consumption.

[0107] Optionally, in step S302, there is also the following processing, and the specific operation flow is as follows:

[0108] Compare the multiple estimated peak power consumptions with the preset temperature rise power threshold to obtain the number of excess operation units that are greater than the power threshold among the multiple estimated peak power consumptions;

[0109] If the number of excess operation units is greater than a preset number threshold, temperature rise status information carrying an estimated temperature rise alarm is generated.

[0110] During implementation, the main controller first compares multiple estimated peak power consumptions with a preset heating power threshold, and obtains the number of multiple estimated peak power consumptions that is greater than the power threshold, which is referred to as the number of excess operating units.

[0111] Then, when the number of excess operating units exceeds the preset threshold, the main controller generates temperature rise status information with an estimated temperature rise alarm, so that the staff can reduce power or temperature in time, thereby reducing the harm caused by the continuous temperature rise of the plum blossom moving contact.
