Description

Technical Field

[0001] The invention belongs to the technical field of monitoring secondary equipment of relay protection in power systems, and in particular relates to a sliding and expandable transformer substation pressure plate state monitoring component and method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The substation pressure plate is the bridge and link between the relay protection device or the automatic measurement and control device and the external wiring, which is directly related to whether the protection function and action output can function normally.

[0004] Substation pressure plates can be divided into functional pressure plates and outlet pressure plates according to their functions, which will be referred to as pressure plates in the following description. Among them, the functional pressure plate is a necessary condition for determining whether the protection function can be put into use; while the outlet pressure plate is mainly for the convenience of operation and maintenance work, which can determine whether the tripping coil of the relay protection device and the circuit breaker is connected. Due to its particularity, its input status can only be checked manually. When the operation mode of the power system of the substation changes, it often involves the separation, combination and verification of multiple protection pressure plates of the multi-sided protection panel cabinet.

[0005] There is no dedicated monitoring system for checking the traditional pressure plate. Although a series of measures have been formulated through operation management regulations to ensure the correctness of the pressure plate position, the problem cannot be fundamentally solved. It still depends entirely on the responsibility and actual level of the operating personnel. Once the error is made, it will directly affect the realization of the relay protection function. In serious cases, it will cause the protection to refuse to operate or malfunction, which will lead to a large-scale power outage. Therefore, in recent years, many substations have invested in pressure plate monitoring systems to deal with this problem.

[0006] However, the existing platen monitoring systems and monitoring methods still have some technical problems, such as:

[0007] (1) Most existing pressure plate monitoring systems only have an independent data processor to analyze and process the data collected by the various sensors used to monitor the pressure plate status. This system design, in which a single data processor performs all computing tasks, has low computing efficiency and cannot guarantee real-time performance, making it difficult to apply to substation pressure plate monitoring work in more complex situations.

[0008] (2) The existing platen monitoring method only considers directly judging the open and closed state of the platen, and does not question the accuracy of the judgment result. However, whether it is when the sensor is used to collect the platen data or when the data processor is used to analyze the collected data, any process may result in misjudgment; therefore, the accuracy of this unconditional trust single-process platen monitoring method is not high.

[0009] (3) The actual layout of the pressure plates in many substations has different spacings and uncertain numbers. The existing pressure plate monitoring system can either only collect the pressure plate status at a fixed spacing, or the adjustable pressure plate spacing is limited, making it difficult to apply to different scenarios. It is impossible to achieve full coverage, real-time monitoring and intelligent verification of the pressure plate status, and its universality is poor. Summary of the invention

[0010] In order to overcome the shortcomings of the above-mentioned prior art, the present invention provides a sliding and expandable substation pressure plate status monitoring component and method, which can realize real-time collection and intelligent verification of the status of pressure plates under different numbers of conditions while ensuring calculation efficiency, thereby realizing effective monitoring of substation pressure plates.

Specifically: the opening and closing position information of the pressure plate is obtained.

[0047] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0048] It should be noted that the terms used herein are for describing specific embodiments only and are not intended to be limiting of exemplary embodiments according to the present invention.

[0049] In the absence of conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other.

[0050] Embodiment 1

[0051] This embodiment discloses a sliding and expandable substation pressure plate state monitoring assembly.

[0052] like Figure 1 As shown, a sliding and expandable substation pressure plate state monitoring component includes: a guide rail unit, a collection unit, a collection unit and a host;

[0053] The guide rail unit is a long strip bottom plate, and a plurality of parallel rails are arranged in the length direction of the long strip bottom plate;

[0054] The collecting unit is movably arranged on the track of the long strip bottom plate and is in electrical contact with the track; the collecting unit is used to collect the pressure plate information, judge the opening and closing state of the pressure plate according to the obtained pressure plate information, and send the obtained opening and closing state to the collecting unit through the guide rail unit;

[0055] The collection unit is used to judge whether the working state of the pressing plate is normal according to the obtained separation state, and upload the obtained working state of the pressing plate to the host;

[0056] The host is used to summarize the working status of the obtained pressing plate and monitor the changes of the working status of the pressing plate in real time.

[0057] Based on the above-mentioned substation pressure plate state monitoring component, the present invention can realize real-time collection and intelligent verification of the state of pressure plates under different numbers of conditions on the basis of ensuring calculation efficiency, thereby realizing effective monitoring of the substation pressure plates. In order to facilitate the understanding of the technical solution of the present invention, the following further explains and illustrates the various specific units and specific implementation methods of the substation pressure plate state monitoring component in the present invention.

[0058] like Figure 3 , Figure 4 As shown, the guide rail unit also includes a long strip shell, the size and outer edge shape of the long strip shell match the long strip bottom plate, and is used to be fixed below the long strip bottom plate; and the long strip shell and the long strip bottom plate can be cut and set, so the number of collection units can be expanded. Specifically, the long strip bottom plate can be fixed above the shell by inserting it into the shell bottom slot of the long strip shell.

[0059] like Figure 2 As shown, a long strip upper cover is also arranged above the long strip bottom plate. The size and outer edge shape of the long strip upper cover are adapted to the long strip bottom plate, and is used to be fixed above the long strip bottom plate.

[0060] Furthermore, the guide rail unit serves as the communication hub between the aggregation unit and the collection unit, and also as the sliding guide rail of the collection unit, providing bus power supply and communication for the collection unit, and the length can be trimmed at will; in other words, the guide rail unit is essentially a base track with multiple lines, without logic devices and circuit devices, and is the medium between the collection unit and the aggregation unit.

[0061] like Figure 5 As shown, the acquisition unit includes an acquisition unit body and a sensor; wherein the sensor is used to collect the pressure plate information, and at the same time, a first CPU processor is embedded inside the acquisition unit body, which is used to judge the opening and closing state of the pressure plate according to the pressure plate information collected by the sensor, and send the obtained opening and closing state to the collection unit through the guide rail unit. In order to ensure the accuracy of data collection, the sensor selected in this embodiment is an omnipolar magnetic induction sensor, which is used in conjunction with a magnetic component that can be installed on the pressure plate (i.e., the relay protection auxiliary switch group). When the opening and closing state of the pressure plate changes, it can be sensed by the sensor, thereby realizing the acquisition of the opening and closing position information of the pressure plate.

[0062] Since the acquisition unit has an independent CPU, the communication mode between the acquisition unit and the collection unit can be bus communication, that is, one collection unit can manage multiple acquisition units through only two data lines. At the same time, the acquisition unit can also achieve functional expansion according to changes in actual applications, replacing the omnipolar magnetic induction sensor with other types of sensors, and realizing the collection of the opening and closing position information of the pressure plate in other sensing forms, that is, the sensor used in the present invention is a broad type of sensing device, not limited to a specific sensor.

[0063] Furthermore, a plurality of sliding contacts are arranged below the main body of the collection unit; wherein the number and positions of the sliding contacts match the tracks on the long strip bottom plate, so that the collection unit is movable on the bottom plate.

[0064] Furthermore, the collection unit is configured with an independent number, and its number can be modified through a computer tool, each number corresponds to a pressure plate position information, and the back of the collection unit has multiple sliding protrusions (contacts) corresponding to the multiple tracks on the guide unit.

[0065] like Figure 2 , Figure 5 As shown, in this embodiment, the number of parallel tracks arranged along the length direction of the long strip bottom plate is four; correspondingly, the number of sliding contacts arranged below the collection unit body is four, and the positions of the four sliding contacts just match the positions of the tracks, so as to realize that the collection unit is movable on the bottom plate. Specifically, the connection between the collection unit and the guide rail unit is a non-fixed connection. The collection unit body on the collection unit is connected to the track on the guide rail unit through four contacts, and can slide arbitrarily on the guide rail unit, and at the same time realize bus communication and power supply of the collection unit by the collection unit. Based on this slide rail design, no matter what the spacing between the pressure plates is, the collection unit can be flexibly slid for collection, which is not limited by the length of the wire harness, and can easily adapt to all types of pressure plate spacings at the substation site. Furthermore, of the four tracks arranged on the long strip bottom plate, two are used for power supply and the other two are used for bus communication.

[0066] The collection unit includes a collector and a second CPU processor; wherein the collector is used to receive the separation and combination status, and the second CPU processor is used to determine whether the working status of the pressure plate is normal according to the obtained separation and combination status, and upload the obtained working status of the pressure plate to the host. In other words, the collection unit also has an independent CPU, and its function is to manage all the collection units through the guide rail unit, and to power the collection units through the guide rail unit, that is, to collect the sampling information of the collection units, and to determine whether the working status of the collection units is normal by analyzing the collected information. Specifically, if the collection unit does not receive the information of the collection unit for a long time, it can be determined that the collection unit is abnormal; in addition, in this embodiment, the collection unit is also equipped with a battery power supply module, which can power the collection unit and several collection units at the same time.

[0067] Furthermore, the entire substation pressure plate status monitoring component adopts a low-power operation mode, so when using a battery-powered module, the system can also operate normally for many years; at the same time, it can be installed under power without affecting the normal operation of the pressure plate, avoiding the problem of mis-opening or mis-closing of the pressure plate and accidental electric shock when the magnetic components need to be connected during pressure plate status detection, which is beneficial to improving the efficiency of pressure plate status collection and the convenience, speed and safety of construction.

[0068] like Figure 6 As shown, the collection unit communicates with the host through the CAN bus; at the same time, the collection unit communicates with the acquisition unit through the 485 bus, and the collection unit can power the acquisition unit through the rail unit. In addition, the host can perform OTA program upgrades on all the collection modules and acquisition modules hanging under it to meet the upgrade requirements that may arise in actual applications.

[0069] Based on the above-mentioned substation pressure plate status monitoring component, a collection unit manages multiple collection units, and a host monitors multiple collection units; each unit is equipped with an independent processor to perform different computing tasks. Therefore, it can better ensure the computing efficiency and real-time monitoring of substation pressure plates, and is more suitable for substation pressure plate monitoring work in more complex situations; on the basis of ensuring computing efficiency, it can realize real-time collection and intelligent verification of the status of pressure plates in different quantities, thereby realizing effective monitoring of substation pressure plates.

[0070] Embodiment 2

[0071] This embodiment discloses a sliding and expandable substation pressure plate status monitoring method.

[0072] like Figure 7 As shown, a sliding and scalable substation pressure plate state monitoring method includes:

[0073] Step S1, collecting pressure plate information based on sensors.

[0074] In this embodiment, an omnipolar magnetic induction sensor is used as a sensor for collecting pressure plate information. Specifically, the omnipolar magnetic induction sensor is used in conjunction with a magnetic component that can be installed on the pressure plate (i.e., the relay protection auxiliary switch group). When the opening and closing position state of the pressure plate changes, it can be sensed by the sensor, thereby realizing the acquisition of the opening and closing position information of the pressure plate.

[0075] Step S2, judging the opening and closing state of the pressure plate according to the obtained pressure plate information, specifically: obtaining the opening and closing position information of the pressure plate, and when the opening and closing position information obtained at two adjacent moments has not changed, judging that the pressure plate state has changed from the open position to the closed position; when the opening and closing position information obtained at two adjacent moments has changed, re-executing a second judgment, performing anti-shake processing and verification on the opening and closing position information, and if the duration of the change in the pressure plate state is longer than the shake time, uploading the opening and closing state information of the pressure plate.

[0076] When the omnipolar magnetic induction sensor in the acquisition unit acquires the opening and closing position information of the pressure plate, the first CPU processor in the acquisition unit can independently implement logical judgment, such as Figure 8 As shown, it is assumed that T1 and T2 are two adjacent acquisition moments for the omnipolar magnetic induction sensor to collect the opening and closing position information of the pressure plate. At time T1, the collected information is recorded as S1; at time T2, the collected information is recorded as S2. If the opening and closing position information does not change during the process from T1 to T2, it can be determined that the pressure plate has changed from the open position to the closed position; if the opening and closing position information changes, the judgment process is restarted. After multiple sampling and analysis, the above anti-shake processing and verification are performed on the opening and closing information. If the state change of the pressure plate is maintained within the jitter time, it will not be uploaded as valid closing position information. If the state change of the pressure plate is maintained for more than the jitter time, it will be uploaded as valid information; among them, the anti-shake time can be customized to achieve stable and reliable opening and closing position detection.

[0077] The acquisition unit can independently judge through the first CPU processor during the process of the omnipolar magnetic induction sensor acquiring the opening and closing position information of the pressure plate, and filter the jitter of the pressure plate in the above manner, thereby achieving stable and reliable opening and closing position detection.

[0078] Step S3: judging whether the working state of the pressing plate is normal according to the obtained separation state, and uploading the obtained working state of the pressing plate to the host.

[0079] The collection unit includes a collector and a second CPU processor; wherein the collector is used to receive the separation and combination status, and the second CPU processor is used to determine whether the working status of the pressure plate is normal according to the obtained separation and combination status, and upload the obtained working status of the pressure plate to the host. The second CPU processor can determine whether the working status of the collection unit is normal by analyzing the information collected by the collector. Specifically, if the collection unit does not receive information from the collection unit for a long time, it can be determined that the collection unit is abnormal; in addition, the time period for which the collection unit does not receive information from the collection unit before determining that the collection unit is abnormal can be set according to actual conditions, and this embodiment does not impose specific restrictions on this.

[0080] When the collection unit monitors the working status of the pressure plate, it can issue an alarm in time to eliminate equipment hazards, which can greatly reduce the number of inspections of the substation pressure plate and improve the safe operation level of unmanned substations; thereby reducing power outage time and ensuring power supply reliability and the continuity of social production activities.

[0081] Step S4: Summarize the working status of the obtained pressing plate based on the host, and monitor the changes of the working status of the pressing plate in real time.

[0082] The host collects the sampling information from the collection unit through the CAN bus and supplies power to the collection unit; the collection unit is responsible for collecting the sampling information from the collection unit through the 485 bus and supplies power to the collection unit; there are several types of collection units that can cover most types of pressure plates in substations, which are used to collect the actual opening and closing position information of the pressure plates and pass the sampling information to the collection unit.
