The test lines and the test principle of the two testers are completely different, the test lines and the interfaces of the existing insulation resistance tester and the dielectric loss tester are different, so that the insulation resistance and the dielectric loss tester need to be disconnected and connected with two test wires, and the test wires need to be repeatedly climbed and replaced, so that the working efficiency is seriously influenced, and the risk of high-altitude falling is increased.

The Chinese patent publication No. CN103309779A discloses a method for detecting the state of secondary equipment of an intelligent substation, which comprises the following steps: firstly, configuring corresponding equipment detection schemes for secondary equipment of each type, compiling detection scheme codes corresponding to the secondary equipment of each type, generating executable binary running intermediate codes by the detection scheme codes, reading the binary intermediate codes of the equipment detection schemes corresponding to the secondary equipment types when detecting, running the binary intermediate codes on a virtual machine to obtain detection values of the secondary equipment, and judging the running state of the secondary equipment according to the detection values by an intelligent substation automation system.

Disclosure of Invention
In order to overcome the defects in the prior art, the invention discloses an electrical detection wiring conversion device, which is provided with an input port connected with a detected object, an output port used for being connected with a detection instrument and a multi-way switch. According to the invention, the multi-way switch performs specific electrical detection on at least one detected object through a mechanical switching mode, wherein the multi-way switch can promote to provide at least one signal related to the mechanical switching period to the detection instrument during the mechanical switching period so as to configure a virtual machine environment related to simulation of at least one detected object connected with the multi-way switch on the detection instrument.
Common detecting instruments often have different detecting environments for various kinds of equipment, sometimes need to measure multiple groups of data for a long time under the unattended condition, sometimes need to switch from a first detected object to a second detected object and then return to the first detected object for continuous measurement. Such measurements may last for a period of several months at most, for example in order to find the cause of some sporadic events. It is common practice to connect multiple test devices at the correlation device to keep track of the correlation signal. The joint arrangement of multiple devices is naturally possible, but it is desirable to use fewer devices for long-term measurement tasks in substations where the devices interfere with each other and are spatially limited. In addition, although the switching is preferable in an electric control mode, the electric control switching involves a complicated timing problem, and for an unattended intelligent substation comprehensive protection room, the timing synchronization is difficult to achieve because of complete shielding of GPS signals. Therefore, the invention adopts a reliable mechanical switching mode, and considers the crosstalk problem possibly caused by mechanical switching. Setting up multiple virtual machines in the same device, and processing multiple data simultaneously is very advantageous for synchronously monitoring multiple signals/data of multiple devices, because the signals/data may have a certain correlation with each other, and judging by two independent devices also lacks real-time performance. Two virtual machines on the same physical device can synchronously process the same data in real time, and determine the data fluctuation with high precision under the same physical clock, for example, the virtual machines are helpful for determining the root cause of voltage sag.
According to the invention, the multi-way switch is preferably used for connecting or disconnecting at least part of the wiring contacts with corresponding wiring ports, the wiring contacts comprise a movable contact, a first stationary contact, a second stationary contact and wiring contacts, the movable contact is arranged on an input end, the first stationary contact and the second stationary contact are arranged on the output end, the input end is used for realizing circuit selection of the multi-way switch by connecting or disconnecting the movable contact configured by the input end with the first stationary contact and the second stationary contact configured by the output end, and at least one signal related to the mechanical switching period provided for the detection instrument is provided in response to the connection or disconnection.
The invention realizes time-sharing operation work 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 switch is executed, the electrical detection wiring conversion device determines at least one signal which is to be provided for the detection instrument and is related to the mechanical switching period according to the travel direction and/or the current position of the movable contact. And in response to receiving the signal, setting up or initializing a virtual machine running environment corresponding to the corresponding connected detected object on a detection instrument in a real machine form, so as to execute a related test. Here, the "at least one signal associated with the mechanical switching period" can be checked simply by the travel direction and the current position in addition to the time-sharing definition, which is particularly simple for the case of the electrical detection wiring conversion device according to the invention provided with a plurality of groups of multiplex switches.
According to the invention, the multi-way switch of the electrical detection switching device preferably further 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 is to be used to form at least one signal related to the mechanical switching. To avoid circumventing design considerations, although not preferred, the present invention also provides: the control end of the electrical detection wire conversion device can also be an embedded detection instrument capable of building a virtual machine environment, for example, an ARM architecture or X86 architecture-based real machine can build a plurality of virtual machines in a container mode, and at least one detected object connected according to the invention can not only provide the detection instrument externally connected with the electrical detection wire conversion device with virtual machine environment parameters for initializing simulation related to corresponding detected objects, but also can execute simulation detection by means of the virtual machines by means of the embedded detection instrument.
According to the present invention, preferably, a set of virtual machine environment parameters required for simulating each object to be detected is stored in advance in a detection instrument of the electrical detection wire conversion device, wherein the detection instrument can build 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 individual test objects, several sets of signals relating to the state analysis are provided to the test instrument for each test object in a time-sharing manner via the wire conversion device and by means of its mechanical switching.
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 a switching signal, because the intelligent substation comprehensive protection room often adopts a very high-level shielding measure, and not only does not have a GPS signal, but also is difficult to access 4G and 5G data. However, the electrical detection wiring conversion device can realize data access through a wired interface such as an optical fiber and the like by means of an automatic control system of the intelligent substation. When the electrical detection wiring conversion device is connected to an automatic control system of an intelligent substation, the electrical detection wiring conversion device can read 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 for more accurately analyzing and determining various data.

The invention relates to an electrical detection system, which comprises an electrical detection wiring conversion device 200, an object 310 to be detected and at least two detection instruments 320 for detecting different electrical parameters;
the multi-way switch 210 of the electrical detection wire conversion device 200 performs specific electrical detection on 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 detection instruments 320 for detecting different electrical parameters in a time-sharing manner during the mechanical switching period, so as to configure virtual machine environments related to simulation of the at least one detected object 310 connected with the multi-way switch 210 on the at least two detection instruments 320.
The following is a detailed description with reference to fig. 1 to 6.
Example 1
The present embodiment provides an electrical detection wiring conversion device 200, which can selectively connect a detection instrument 320 through a multi-way switch 210 when an input port 220 is connected to an object 310 to be detected. The detecting instrument 320 includes an insulation resistance tester and a dielectric loss tester. The input port 220 is connected with an object 310 to be detected such as a power transformer, a coupling capacitor, etc.; the output port 230 is connected to a detection device 320 such as an insulation resistance tester and a dielectric loss tester. The multiway switch 210 comprises a set of movable contacts 201 and a plurality of sets of stationary contacts, wherein the stationary contacts comprise 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. The first stationary contact 202, the second stationary contact 203 are connected to the output port 230, and a set of stationary contacts are connected to a detection instrument 320. The multi-way switch 210 connects the movable contact 201 to the first stationary contact 202 and the second stationary contact 203 connected to the specific detecting device 320, thereby performing specific electrical detection on the object 310. The multi-way switch 210 changes the position of the movable contact 201, thereby switching the first stationary contact 202 and the second stationary contact 203 connected to the movable contact 201, and thereby changing the electrical detection item.
Referring to fig. 1, the electrical detection wire conversion device 200 is preferably provided with an input port 220 connected to a subject 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 ports 230 are provided with two sets of at least two ports for connecting different detection instruments 320. The multiple switch 210 includes a plurality of connection contacts, and ports of the connection conversion device 200 are in one-to-one correspondence with the connection contacts. The input port 220 and the output port 230 are connected to the multiway switch 210 through a combination conductor 240, respectively. The multiplexing switch 210 is used to connect or disconnect at least some of the line contacts to or from the corresponding wire connection ports.
During electrical testing, the movable contact 201, the first stationary contact 202, the second stationary contact 203 and the wires within the conversion device 200 will be subjected to a maximum of 10kV ac voltage. When a high voltage current passes through the multi-way switch 210 and the wires within the switching device 200, a magnetic field is necessarily generated therearound that interferes with the electrical test. The combined conductor 240 in this embodiment uses the opposite directions of the current flow in the two conductors 102 to cancel each other out by arranging the conductors 102 flush and minimizing the distance between the conductors 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 movable contact 201 is disposed at the input terminal 213, and the first stationary contact 202 and the second stationary contact 203 are disposed at the output terminal 215. The input terminal 213 connects or disconnects the movable contact 201 configured by the input terminal to or from the first and second stationary contacts 202 and 203 configured by the output terminal 215, so as to realize circuit selection of the multiway switch 210.
Preferably, the multiway switch 210 further comprises a control terminal 211, a first transmission 212 and a second transmission 214. Preferably, the first transmission 212 and the second transmission are both screw-driven structures, including a motor and a screw. Preferably, the motors of the first transmission mechanism 212 and the second transmission mechanism 214 are respectively electrically connected with the control end 211. The first transmission 212 and the second transmission 214 are perpendicular to each other. The input 213 is arranged on the spindle of the first transmission 212. The output 215 is arranged on the spindle of the second transmission 214. The control end 211 sends a signal to the motor of the first transmission mechanism 212 to make the motor rotate in the opposite direction, so that the input end 213 reciprocates on the screw rod of the first transmission mechanism 212, and the first stationary contact 202 and the second stationary contact 203 to which the movable contact 201 is to be connected are selected. In the case where the movement of the input terminal 213 is stopped, that is, in the case where the movable contact 201 determines the stationary contact object to be connected and the position is fixed, the control terminal 211 transmits a docking signal to the motor of the second transmission mechanism 214, and the motor of the second transmission mechanism 214 rotates to bring the output terminal 215 along the screw of the second transmission mechanism 214 to approach the input terminal 213 until the movable contact 201 completes docking with the first stationary contact 202 and the second stationary contact 203.
When the electrical detection is finished, the control end 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 enable the output end 215 to be far away from the input end 213 along the screw rod of the second transmission mechanism 214 until the movable contact 201 is disengaged from the first stationary contact 202 and the second stationary contact 203.
In the case of switching the electrical detection items, the control end 211 sends a disengagement signal to the second transmission mechanism 214, and the second transmission mechanism 214 drives the output end 215 to disconnect the movable contact 201 from the first stationary contact 202 and the second stationary contact 203 by being far away from the input end 213. In the case that the movable contact 201 is disconnected from the first stationary contact 202 and the second stationary contact 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 stationary contact 202 and the second stationary contact 203 so as to select the first stationary contact 202 and the second stationary contact 203 corresponding to different detecting instruments 320. In the case that the input end 213 selects the first stationary contact 202 and the second stationary 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 approach the input end 213 to realize the connection between the movable contact 201 and the first stationary contact 202 and the second stationary contact 203, thereby completing the switching of the electrical detection items.
The input terminal 213 is connected to the movable contact 201 and the input port 220 through the combined wire 240, and the output terminal 215 is connected to the first stationary contact 202, the second stationary contact 203 and the output port 230 through the combined 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 specific electrical detection on at least one corresponding detected object by means of mechanical switching. According to a preferred embodiment, the multi-way switch 210 provides at least one signal associated with the mechanical switching period to the detection instrument during the mechanical switching period, the signal being used to configure a virtual machine environment associated with a simulation of at least one object to be detected to which the multi-way switch is connected on the detection instrument 320. The detection instrument may store or be capable of acquiring detection item information from an upper network, where the detection item information may include data such as a detection period, a sampling frequency, and the like, and the multi-way switch 210 mechanically switches a connection relationship between a stationary contact and a movable contact between an input end and an output end based on the received detection item information, especially based on information such as a sampling site of a sampling port, so as to implement "mechanical switching" to implement specific electrical detection on at least one detected substance. The "at least one signal related to the mechanical switching period" is provided by the control terminal 211 in the multi-way switch 210, and this information is preferably used or can be processed to determine the type of the object 310 currently realizing the detection circuit by mechanical switching of the multi-way switch, for example, based on the conduction of a specific set of stationary contacts and moving contacts, the current type information of the object can be known from the relation of the preconfigured contact combinations and the object. In this way, the set of virtual machine environment parameters required for simulating each object to be detected is stored in advance in the detecting instrument or can be loaded from a higher-level network, and the detecting instrument 320 can build a virtual machine cluster in a container manner so as to simulate each object to be detected 310 in parallel. The detection apparatus determines the corresponding set of virtual machine environment parameters, i.e. at least one or more virtual machine environment parameters for a type of object to be detected, by means of a "switching period related signal" provided by the control terminal 211 in the multi-way switch 210, which contains or can be processed as the type of object to be detected 310.
According to a preferred embodiment, during parallel simulation of each object 310, several sets of signals relating to the analysis of the object's state are provided to the detection instrument in time-sharing for each object 310 via the multi-way switch 210 and by means of its mechanical switching. In the application scenario of the scheme, 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 correspondingly. In this embodiment, the implementation path of the multiway switch 210 for providing the state analysis related signal to the detection instrument for each detected object 310 in a time sharing manner by means of mechanical switching may be: the plurality of objects to be detected 310 are respectively configured with separate input ends or stationary contacts, and accordingly, the modules with different detection functions configured for different objects to be detected by the detection apparatus also have different output ends or stationary contacts, and if there is only one wire, that is, only one group of input ends and output ends can be communicated with each other through the wires of the multiple switches at the same time, the multiple switches switch the connection relationship between the input ends and the output ends based on the mechanical manner, so that it is possible to provide a plurality of groups of signals related to the analysis of the states of the objects to be detected to the detection apparatus in a time-sharing manner.
The above-mentioned scheme, especially applied to the scenario of dielectric loss and insulation resistance experiments, for example, includes a detecting instrument 320 at least used for detecting two different electrical parameters, in which the multi-way switch 210 implements specific electrical detection on the corresponding at least one detected object 310 through a mechanical switching manner, 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 for a virtual environment configuration related to simulation of at least one detected object 310 connected to the multi-way switch 210 on at least two detecting instruments during the mechanical switching period. In this scenario, a single object to be tested is provided with at least two different electrical parameters to be tested, and at least two test instruments 320 configured accordingly need to determine type information of the object to be tested to configure its simulation-related virtual environment, so that the multi-way switch 210 is configured to be capable of performing mechanical switching to provide signals related to configuring virtual machines to the two test instruments 320 in a time-sharing manner. Further, the two detecting apparatuses 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 detecting apparatuses 320 can mutually interact data, so as to simulate the detected object 310 simultaneously with at least two electrical parameters or with two units to be detected in real time. One of the two detecting apparatuses 320 may be equipped with a plurality of virtual machines, and the other detecting apparatus 320 may be a physical machine, instead of employing a virtual machine. At this time, the two detecting apparatuses 320 build a virtual machine cluster in a virtual-real combination manner, and both can detect (or detect in a simulation manner) the respective objects 310 to be detected in parallel. The two detecting apparatuses 320 may be mounted with virtual machines, and the plurality of virtual machines are connected to each other by a wire between the two detecting apparatuses 320 to form a cluster, so that the virtual machines can mutually interact data for integrally simulating the object 310 having at least two electrical parameters or two units to be detected in real time. For example, in a first time, the multi-level switch establishes a connection between the detected object 310 and the first detecting instrument, the first detecting instrument benefits from information formed by mechanical switching to form a virtual machine environment configuration, and meanwhile, interconnection and intercommunication are realized by means of multiple virtual machines, although the second detecting instrument still needs to wait for circuit communication with the detected object 310 to actually configure the virtual environment of the detected object, through the interconnection and intercommunication, the second detecting instrument can still perform configuration preprocessing on a part of contribution information (such as a base current, a noise background value and the like of the detected object) transmitted by the first detecting instrument before the detection connection is actually established through the multi-level switch, so that the detection efficiency of the cross-instrument is accelerated, especially for an integrated protection room of an electric system with a higher data protection level, and based on data interaction of multiple virtual clusters, because data interconnection across actual devices does not exist in some cases, but data interconnection in a single device exists, and therefore, the problem that due to lack of an actually available data transmission means (such as 4G and 5G communication means), the detection efficiency of each detecting device is low or even data cooperation of multiple detected objects can be avoided.
