Disclosure of Invention
Aiming at the defects of the prior art, the invention discloses an electrical detection wiring conversion device which is provided with an input port connected with an object to be detected, an output port used for connecting a detection instrument and a multi-way switch. According to the invention, the multiway switch performs a specific electrical detection of the corresponding at least one detected object by means of mechanical switching, wherein the multiway switch can facilitate providing the detection instrument with at least one signal related to the mechanical switching during the mechanical switching, so as to configure a virtual machine environment on the detection instrument related to the simulation of the at least one detected object connected with the multiway switch.
Common detection instruments often have different detection environments for various types of equipment, sometimes need to measure multiple groups of data under the unattended condition for a long time, sometimes need to switch from a first detected object to a second detected object, and then return to the first detected object to continue measuring. Such measurements may last for a period of several months at most, for example to discover the cause of certain contingencies. It is conventional practice to connect multiple test devices at the correlation device to continuously track the correlation signal. The way in which multiple devices are arranged in a combined manner is inherently feasible, but less devices are desirable to perform long-time measurement tasks in substations where the devices interfere with each other and the space is limited. In addition, although the switching in the electric control mode is preferable, the electric control switching involves a complicated timing problem, and for an unattended intelligent substation comprehensive protection room, timing synchronization is difficult to achieve due to the fact that GPS signals are completely shielded. Therefore, the invention adopts a reliable mechanical switching mode and considers the problem of crosstalk possibly caused by mechanical switching. The virtual machines are built in the same equipment, and the simultaneous processing of multiple items of data is very beneficial for synchronously monitoring multiple signals/data of multiple equipment, because the signals/data may have certain relevance with each other, and the judgment performed by two independent equipment is lack of real-time performance. And two virtual machines on the same physical device can synchronously process the same data in real time, and determine data fluctuation with high precision under the same physical clock, for example, the method is helpful for determining the root of voltage sag.
According to the invention, preferably, the multiway switch is used for connecting or disconnecting at least part of the wiring contacts with corresponding wiring ports, the wiring contacts comprise movable contacts, first fixed contacts, second fixed contacts and wiring contacts, the movable contacts are arranged on the input end, the first fixed contacts and the second fixed contacts are arranged on the output end, the input end is connected or disconnected with the first fixed contacts and the second fixed contacts arranged on the output end through the movable contacts arranged on the input end, so that circuit selection of the multiway switch is realized, wherein at least one signal relevant to mechanical switching period provided for the detection instrument is provided in response to the connection or disconnection.
The invention realizes time-sharing operation without timing through simple and reliable mechanical switching of the movable contact, the first fixed contact and the second fixed contact, and because the travel and the position of the movable contact of the multi-way switch are determined, after the multi-way switch performs switching, the electric detection wiring switching device determines at least one signal related to the mechanical switching period to be provided for the detection instrument according to the travel direction and/or the current position of the movable contact. And in response to the signal, building or initializing a virtual machine operating environment corresponding to the correspondingly connected detected object on the detection instrument in the form of a real machine so as to execute related tests. Here, "at least one signal related to the mechanical switching period" may be simply verified by the stroke direction and the current position, in addition to being clear in time sharing, and in the case of the electrical detection wiring switching apparatus of the present invention configured with a plurality of sets of multi-way switches, the switching backtracking is particularly simple.
According to the invention, the multiswitch of the electrical test patching switching device preferably also comprises a control terminal, which in the invention can be used to control the movable contact, the first stationary contact and the second stationary contact, for example to determine its current position, its historical position, its travel and its travel direction, which information will be used to form at least one signal relating to the mechanical switching. To avoid circumventing design considerations, the invention also provides, although not preferred: the control end of the electrical detection wiring conversion device can also be an embedded detection instrument capable of building a virtual machine environment, for example, a real machine based on an ARM framework or an X86 framework, which can build a plurality of virtual machines in a container mode, and at least one detected object connected according to the invention not only can provide a detection instrument externally connected with the electrical detection wiring conversion device with virtual machine environment parameters for initializing simulation related to the corresponding detected object, but also can execute simulation detection by means of the virtual machine by means of the embedded detection instrument.
According to the present invention, preferably, a virtual machine environment parameter set required for simulating each object to be detected is stored in advance in a detection instrument of the electrical detection wiring conversion device, wherein the detection instrument can set up a virtual machine cluster in a container manner so as to simulate each object to be detected in parallel.
Preferably, during the parallel simulation of the respective test object, several sets of state analysis-related signals are provided to the test instrument for the respective test object in time intervals via the wiring switching device and by means of the mechanical switching thereof.
The reason why the virtual machine environment parameter set is preferably stored in the electrical detection wiring conversion device in advance and the virtual machine initialization of the detection instrument is facilitated by sending the switching signal is that the intelligent substation comprehensive protection room usually adopts a high-level shielding measure, so that not only no GPS signal is available, but also 4G and 5G data are difficult to access. However, the electrical detection wiring conversion device can realize data access by means of an automatic control system of an intelligent substation through wired interfaces such as optical fibers. When the device is connected to an automatic control system of an intelligent substation, the electrical detection wiring conversion device can read the state parameters from the automatic control system and forward the state parameters to a connected detection instrument or a virtual machine on the detection instrument so as to more accurately analyze and determine various types of data.

Detailed Description
The invention relates to an electrical detection system, which comprises an electrical detection wiring conversion device 200, an object to be detected 310 and at least two detection instruments 320 for detecting different electrical parameters;
the multi-way switch 210 of the electrical detection wiring switching device 200 performs specific electrical detection on the corresponding at least one detected object 310 through a mechanical switching manner, wherein the multi-way switch 210 provides at least one signal related to the mechanical switching period to the at least two detecting instruments 320 for detecting different electrical parameters in a time sharing manner during the mechanical switching period so as to configure a virtual machine environment related to simulation of the at least one detected object 310 connected with the multi-way switch 210 on the at least two detecting instruments 320.
The following detailed description is made with reference to fig. 1 to 6.
Example 1
The present embodiment provides an electrical detection wire switching device 200, which can selectively connect a detection instrument 320 through a multi-way switch 210 when an object 310 to be detected is connected to an input port 220. The detection instrument 320 includes an insulation resistance tester and a dielectric loss tester. The input port 220 is connected with an object to be detected 310 such as a power transformer, a mutual inductor and a coupling capacitor; the output port 230 is connected to a detection instrument 320 such as an insulation resistance tester and a dielectric loss tester. The multi-way switch 210 includes a set of moving contacts 201 and a plurality of sets of stationary contacts, including a first stationary contact 202 and a second stationary contact 203. The movable contact 201 is connected to the input port 220 and thus to the object 310 to be detected. The first stationary contact 202, the second stationary contact 203 are connected to the output port 230, and one set of stationary contacts is connected to a test instrument 320. The multi-way switch 210 performs a specific electrical test on the object 310 by connecting the movable contact 201 to the first and second stationary contacts 202 and 203 connected to a specific test instrument 320. The multi-way switch 210 changes the position of the movable contact 201, thereby switching the first and second fixed contacts 202 and 203 connected to the movable contact 201, and thus changing the electrical test items.
Referring to fig. 1, preferably, the electrical detection wiring switching device 200 is provided with an input port 220 connected to an object to be detected 310, an output port 230 connected to a detection instrument 320, and a multi-way switch 210. The input port 220 is provided with at least two ports. The output port 230 is provided with a set of two at least two ports for connecting different detection instruments 320. The multi-way switch 210 includes a plurality of connection contacts, and the ports of the connection converting device 200 correspond to the connection contacts one to one. The input port 220 and the output port 230 are connected to the multiplexer 210 through combination conductors 240, respectively. The multiplexer 210 is used to connect or disconnect at least a portion of the wiring contacts to the corresponding wiring ports.
During electrical testing, the movable contact 201, the first stationary contact 202, the second stationary contact 203 and the wires in the transfer device 200 will withstand a maximum of 10kV ac voltage. When high voltage current passes through the multi-way switch 210 and the wires within the inverter device 200, it is necessary to generate a magnetic field around it that interferes with the electrical test. The combined conducting wires 240 in this embodiment are formed by arranging the conducting wires 102 in a flush manner and reducing the distance between the conducting wires 102 as much as possible, so that the magnetic fields generated by the two conducting wires 102 are mutually cancelled out by utilizing the opposite flowing directions of the currents in the two conducting wires 102.
Preferably, the wiring contacts include a movable contact 201 and at least two sets of stationary contacts, each set of stationary contacts including a first stationary contact 202, a second stationary contact 203. The moving contact 201 is disposed on the input terminal 213, and the first and second fixed contacts 202 and 203 are disposed on the output terminal 215. The input terminal 213 realizes the circuit selection of the multi-way switch 210 by connecting or disconnecting the movable contact 201 configured with the first fixed contact 202 and the second fixed contact 203 configured with the output terminal 215.
Preferably, the multi-way switch 210 further includes a control terminal 211, a first transmission 212, and a second transmission 214. Preferably, the first transmission mechanism 212 and the second transmission mechanism are both screw transmission mechanisms, including a motor and a screw. Preferably, the motors of the first transmission mechanism 212 and the second transmission mechanism 214 are respectively connected with the control end 211 through electric signals. The first transmission 212 and the second transmission 214 are perpendicular to each other. The input 213 is arranged on a spindle of the first transmission 212. The output 215 is arranged on the spindle of the second gear 214. The control end 211 sends a signal to the motor of the first transmission mechanism 212 to make the motor rotate forward and backward, so that the input end 213 reciprocates on the lead screw of the first transmission mechanism 212, and the first fixed contact 202 and the second fixed contact 203 to which the movable contact 201 is to be connected are selected. In the case that the input terminal 213 stops moving, that is, the movable contact 201 determines the fixed contact object to be connected and is fixed in position, the control terminal 211 sends a docking signal to the motor of the second transmission mechanism 214, and the motor of the second transmission mechanism 214 rotates to make the output terminal 215 approach the input terminal 213 along the lead screw of the second transmission mechanism 214 until the movable contact 201 is docked with the first fixed contact 202 and the second fixed contact 203.
In the case of ending the electrical detection, the control terminal 211 sends a disengagement signal to the motor of the second transmission mechanism 214, and the motor of the second transmission mechanism 214 rotates to make the output terminal 215 move away from the input terminal 213 along the lead screw of the second transmission mechanism 214 until the movable contact 201 is disengaged from the first and second fixed contacts 202 and 203.
In the case of switching the electrical detection items, the control terminal 211 sends a disengagement signal to the second transmission mechanism 214, and the second transmission mechanism 214 drives the output terminal 215 to disconnect the movable contact 201 from the first and second stationary contacts 202 and 203 by moving away from the input terminal 213. When the movable contact 201 is disconnected from the first and second stationary contacts 202 and 203, the control end 211 sends a signal to the first transmission mechanism 212, and the first transmission mechanism 212 drives the input end 213 to move along the arrangement direction of the first and second stationary contacts 202 and 203 so as to select the first and second stationary contacts 202 and 203 corresponding to different detection instruments 320. Under the condition that the input end 213 selects the first fixed contact 202 and the second fixed contact 203, the control end 211 sends a docking signal to the second transmission mechanism 214, and the second transmission mechanism 214 drives the output end 215 to be close to the input end 213 so as to realize the connection between the movable contact 201 and the first fixed contact 202 and the second fixed contact 203, thereby completing the switching of the electrical detection items.
The input terminal 213 connects the movable contact 201 with the input port 220 through a composite wire 240, and the output terminal 215 connects the first stationary contact 202, the second stationary contact 203, and the output port 230 through the composite wire 240. The control end 211 controls the switching action of the multi-way switch 210 by controlling the first transmission mechanism 212 and the second transmission mechanism 214.
According to the present invention, the multi-way switch 210 performs a specific electrical inspection of the corresponding at least one inspected object by means of mechanical switching. According to a preferred embodiment, the multiswitch 210 provides at least one signal to the instrumentation during the mechanical switching, which signal is used to configure a virtual machine environment on the instrumentation 320 that is associated with a simulation of at least one object under test to which the multiswitch is connected. The detection instrument can store or acquire detection item information from an upper network, the detection item information can comprise data such as a detection period and sampling frequency, and the multi-way switch 210 mechanically switches the connection relation between the fixed contact and the movable contact between the input end and the output end based on the received detection item information, particularly based on information such as sampling sites of a sampling port, so that the corresponding at least one detected substance is electrically detected in a mechanical switching manner. The "at least one signal associated with the mechanical switching period" is provided by the control terminal 211 in the multiswitch 210, and this information is preferably used or can be processed to determine the type of the object 310 currently performing the detection loop through the mechanical switching of the multiswitch, for example, based on the conduction of a specific set of stationary and movable contacts, the type information of the current object can be known from the pre-configured contact combination and object. Based on this, the detection instrument is pre-stored with or can load a virtual machine environment parameter set required for simulating each detected object from an upper network, wherein the detection instrument 320 can build a virtual machine cluster in a container mode to simulate each detected object 310 in parallel. The detecting instrument determines a corresponding set of virtual machine environment parameters by the "signals related to switching period" provided by the control terminal 211 of the multi-way switch 210 and containing or capable of being processed as the type of the detected object 310, that is, at least one or more virtual machine environment parameters are provided to correspond to one type of the detected object.
According to a preferred embodiment, during the simulation of each object under test 310 in parallel, several sets of signals related to the analysis of the state of the object under test are provided to the detection instrument for each object under test 310 in time via the multi-way switch 210 and by means of its mechanical switching. In the application scenario of the present solution, the test object has multiple types, such as a power transformer, a transformer, or a coupling capacitor, and each detected object 310 also has multiple electrical parameters that can be detected. In this embodiment, the implementation path of the multi-way switch 210 for providing the signal related to the state analysis to the detecting apparatus in time division for each detected object 310 by means of mechanical switching may be: the plurality of objects to be detected 310 are respectively configured with a single input end or a stationary contact, correspondingly, the modules with different detection functions configured by the detection instrument for different objects to be detected also have different output ends or stationary contacts, and in the case that only one lead exists, that is, only one group of input ends and output ends can be communicated with each other through the lead of the multi-way switch at the same time, the multi-way switch switches the connection relationship of the input ends and the output ends based on a mechanical mode, so that a plurality of groups of signals related to the state analysis of the objects to be detected can be provided to the detection instrument in a time-sharing manner.
The above solution, especially applied to the scenario of dielectric loss and insulation resistance experiments, for example, includes at least two detecting instruments 320 for detecting two different electrical parameters, in which scenario the multi-way switch 210 performs a specific electrical detection on the corresponding at least one object under test 310 by means of mechanical switching, and the multi-way switch provides at least one signal related to the mechanical switching period to at least two detecting instruments for detecting different electrical parameters in a time-division manner, so as to configure a virtual environment related to simulation of at least one object under test 310 connected to the multi-way switch 210 on the at least two detecting instruments. In this scenario, a single detected object has at least two different electrical parameters to be detected, and at least two detecting apparatuses 320 configured correspondingly need to determine type information of the detected object to configure a virtual environment related to simulation thereof, so the multi-way switch 210 is configured to be capable of performing mechanical switching to provide signals related to configuring a virtual machine to the two detecting apparatuses 320 in a time-sharing manner. Further, the two detection instruments 320 can build a virtual machine cluster in a virtual-real combination manner, so as to simulate each detected object 310 in parallel, and the virtual machine clusters carried by the at least two detection instruments 320 can mutually exchange data, so as to simulate the detected object 310 simultaneously having at least two electrical parameters or two units to be detected in real time. One of the two detection instruments 320 may carry multiple virtual machines, while the other detection instrument 320 may be a physical machine, rather than a virtual machine. At this time, the two detection apparatuses 320 construct a virtual machine cluster in a virtual-real combined manner, and the two apparatuses can detect (or detect in a simulation manner) each object 310 in parallel. The two detecting instruments 320 may both carry virtual machines, and a plurality of virtual machines are connected by a wire between the two detecting instruments 320 to form a cluster, so that the virtual machines can interact data with each other, and are used for simulating the detected object 310 which simultaneously has at least two electrical parameters or two units to be detected in real time. For example, in the first time, the multi-stage switch establishes the contact between the object to be detected 310 and the first detecting apparatus, the first detecting apparatus benefits from the information formed by mechanical switching to form a virtual machine environment configuration, and meanwhile, the interconnection and intercommunication are realized by means of a plurality of virtual machines, although the second detecting apparatus still needs to wait for the circuit communication with the object to be detected 310 to actually configure the virtual environment thereof, through the interconnection and intercommunication, the second detecting apparatus can still perform a part of configuration preprocessing based on part of contribution information (such as the basic current, the noise background value and the like of the object to be detected) transmitted by the first detecting apparatus before actually establishing the detection contact through the multi-stage switch, thereby accelerating the efficiency of cross-apparatus detection, especially for a comprehensive protection room of an electric power system with a high data protection level, the data interaction based on a plurality of virtual clusters, and the data interconnection in a single apparatus because there is no data intercommunication across actual apparatuses in some cases, thereby avoiding the problems that the efficiency of detection of each detecting apparatus for a plurality of objects to be detected is low and even the data is difficult to cooperate due to lack of actually available data transmission means (such as 4G and 5G communication means).
