Description

Technical Field

[0002] Power monitoring system: The power monitoring system uses computers, communication equipment, and measurement and control units as basic tools to provide a basic platform for real-time data acquisition, switch status detection, and remote control of power distribution systems. It can form any complex monitoring system with detection and control equipment and plays a core role in power distribution monitoring. It can help enterprises eliminate isolated systems, reduce operating costs, improve production efficiency, and speed up the response to anomalies in the power distribution process.

[0003] Currently, in many situations in power systems, temporary wiring devices are used to switch on and off the power supply via switches or backup protection circuit breakers (SCBs). In order to ensure reliable power supply to the load, the switch status needs to be obtained in real time. However, most of these switches do not have remote signaling functions, so the switch itself cannot conveniently and timely detect whether it is in a tripped or closed state. Furthermore, existing switch monitoring devices cannot perform detailed monitoring or precise control of different on / off states of multiple wiring groups, making them unsuitable for complex wiring environments.

Example 1

[0027] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a power network switch status monitoring device, which can monitor and classify multiple sets of different wiring on / off conditions, and can quickly perform temporary wiring for multiple sets of lines and flexibly control the different on / off states of multiple sets of wiring.

[0028] Specifically, the dual-position opening and closing unit 100 includes a housing assembly 101, a first double-button adjustment assembly 102 and a second double-button adjustment assembly 103 symmetrically arranged within the housing assembly 101, a strong pressure rod 104 connected to the bottom of the first double-button adjustment assembly 102 and extending one end out of the housing assembly 101, a weak pressure rod 105 connected to the bottom of the second double-button adjustment assembly 103 and extending one end out of the housing assembly 101, two sets of driven assemblies 106 respectively arranged on the strong pressure rod 104 and the weak pressure rod 105, and two sets of connecting assemblies 107 symmetrically arranged on both sides inside the housing assembly 101.

[0029] The strong pressure rod 104 and the weak pressure rod 105 extend out of the housing assembly 101 by the same length, and the length of the strong pressure rod 104 is greater than the length of the weak pressure rod 105.

[0030] The four-phase monitoring unit 200 includes a pressure-bearing module 201 disposed within the housing assembly 101, a control module 202 electrically connected to the pressure-bearing module 201, and a wireless transceiver module 203 electrically connected to the control module 202.

[0031] Furthermore, the housing assembly 101 includes a housing 101a, a mounting plate 101b disposed on one side of the housing 101a, and two sets of lifting access ports 101c symmetrically disposed on the other side of the housing 101a; the top and sides of the housing 101a are provided with multiple sets of adaptive openings.

[0032] Furthermore, the first double-button adjustment assembly 102 and the second double-button adjustment assembly 103 have the same structure. The first double-button adjustment assembly 102 includes a release rod 102a inserted into the housing assembly 101, a first key block 102b disposed on the top of the release rod 102a, a first spring 102c connected to the bottom of the first key block 102b and disposed on the outside of the release rod 102a, a first actuating rod 102d disposed on the inner side of the bottom of the release rod 102a, an opening and closing rod 102e inserted into the housing assembly 101, and a first spring 102c disposed on the bottom of the release rod 102a. The opening and closing rod 102e consists of a second key block 102f at the top, a second spring 102g connected to the bottom of the second key block 102f and disposed on the outside of the opening and closing rod 102e, a second toggle rod 1021 disposed on the inside of the opening and closing rod 102e, a connecting plate 1022 disposed on the outside of the opening and closing rod 102e, a first arc groove connecting plate 102h connected to the top of the connecting plate 1022, and a second arc groove connecting plate 102i disposed above the first arc groove connecting plate 102h and fixedly connected to the top inner wall of the housing assembly 101.

[0033] The bottoms of the first spring 102c and the second spring 102g are both connected to the top of the housing assembly 101, and the second spring 102g is in a compressed state.

[0034] Furthermore, the driven component 106 includes a limiting guide plate 106a disposed at the outer end of the strong pressure rod 104, a third spring 106b connected to the limiting guide plate 106a and connected to the inner wall of the housing component 101, an inclined release block 106c disposed on one side of the limiting guide plate 106a, an inclined locking block 106d disposed on one side of the inclined release block 106c, and a locking groove 106e disposed on one side of the bottom of the inclined locking block 106d;

[0035] The third spring 106b is in a compressed state. The two sets of third springs 106b are connected to the strong pressure rod 104 and the weak pressure rod 105 respectively, and the two sets of third springs 106b have the same strength.

[0036] Furthermore, the communication component 107 includes two sets of insulating support blocks 107a symmetrically arranged within the housing component 101, a conductive block 107b connected to the top of the insulating support block 107a, and a fixed cavity 107c disposed on one side of the insulating support block 107a.

[0037] Preferably, the arc-shaped friction check pad 102h-2 is made of friction material, and the conductive block 107b is made of conductive material.

[0038] Furthermore, a first gap 104a is provided between the strong pressure rod 104 and the pressure-receiving module 201, and a second gap 105a is provided between the weak pressure rod 105 and the pressure-receiving module 201; the length of the first gap 104a is less than the length of the second gap 105a.

[0039] Furthermore, the first arc groove connecting plate 102h and the second arc groove connecting plate 102i are arranged opposite to each other. The first arc groove connecting plate 102h includes an arc groove bearing block 102h-1 and an arc-shaped friction anti-rebound pad 102h-2 disposed in the arc groove bearing block 102h-1.

[0040] Furthermore, it also includes a power supply unit 300, which includes a first power supply 301 and a second power supply 302, a first line 303 connected to the first power supply 301 and fixedly connected to a set of the communication components 107, and a second line 304 connected to the second power supply 302 and fixedly connected to another set of the communication components 107.

[0041] Furthermore, the first actuating lever 102d is positioned above the inclined side of the inclined release block 106c, and the second actuating lever 1021 is positioned above the inclined side of the inclined locking block 106d. The pressure-bearing module 201 is a piezoelectric pressure sensor.

[0042] It should be noted that pressure sensors based on the piezoelectric effect come in many types and models, and can be divided into two categories according to the form of the elastic sensing element and the force-receiving mechanism: diaphragm type and piston type. The diaphragm type mainly consists of a body, a diaphragm, and a piezoelectric element. The piezoelectric element is supported on the body, and the diaphragm transmits the measured pressure to the piezoelectric element, which then outputs an electrical signal that is related to the measured pressure. The control module 202 can be a CPU. The piezoelectric pressure sensor outputs an electrical signal of the measured pressure value to the CPU, and the CPU module sends the measured pressure value electrical signal to the wireless transceiver module for external transmission. The wireless transceiver module can use existing technology.

[0043] During use, temporary wiring and flexible on / off adjustments are possible. Furthermore, precise monitoring of four temporary wiring scenarios is possible to promptly detect operator errors in switching operations, enabling remote monitoring and error prevention. These four scenarios are: fully disconnected, fully connected, only the first power supply 301 connected to the temporary wiring line P1, and only the second power supply 302 connected to the temporary wiring line P2.

[0044] Referring to the diagram, this is the completely disconnected state. There is no contact between the pressure module 201 and the strong pressure rod 104 or the weak pressure rod 105, and the measured value is 0. The measured value of the pressure module 201 is defined as N1 when only the first power supply 301 is connected to the temporary wiring line P1, and N2 when only the second power supply 302 is connected to the temporary wiring line P2. The fully connected state is N3.

[0045] In temporary wiring and flexible on / off adjustment, when only the first power supply 301 needs to be connected to the temporary wiring line P1, referring to the diagram, simply insert the temporary wiring line P1 through the lifting on / off port 101c on one side of the housing 101a into the first arc groove connecting plate 102h and make its top end contact with the insulating bearing block 107a. The temporary wiring line P1 is placed in the arc-shaped friction anti-return pad 102h-2 at the top of the first arc groove connecting plate 102h; then simply press the first key block 102b to release the first key block 102a on one side of the release rod 102a. The actuating lever 102d contacts and presses the inclined side release block 106c, causing the inclined side release block 106c to retract a certain distance and compress the third spring 106b again. The retraction of the inclined side release block 106c causes the strong pressure lever 104 to retract a certain distance as well, thus driving the inclined side locking block 106d to retract. The locking groove 106e at the bottom of the inclined side locking block 106d disengages from the second actuating lever 1021 on one side of the opening and closing lever 102e, thereby releasing the mutual limit lock between the opening and closing levers 102e.

[0046] After the mutual limit locks are released, the compressed second spring 102g will rebound, causing the opening and closing rod 102e to move upward a certain distance. The connecting plate 1022 on one side of the opening and closing rod 102e will control the first arc groove connecting plate 102h to rise as a whole and finally contact and close with the second arc groove connecting plate 102i. At this time, the temporary wiring line P1 set in the first arc groove connecting plate 102h will be tightly clamped by the upper and lower sets of arc-shaped friction anti-return pads 102h-2, and the temporary wiring line P1 will be prevented from detaching by increasing the friction force, thereby achieving the clamping and fixing of the temporary wiring line. The power terminal of the temporary wiring line P1 is connected to the conductive block 107b. The first power supply 301 is fixedly connected to the conductive block 107b through the first line 303, thereby connecting the temporary wiring line P1 to the first power supply 301.

[0047] After the mutual limit locks are released, the release lever 102a springs back to its original position under the action of the first spring 102c, and the opening / closing lever 102e springs back to its original position under the action of the second spring 102g. The strong pressure lever 104 will move a certain distance under the action of the compressed third spring 106b. Similarly, when the second power supply 302 is connected, the weak pressure lever 105 will move the same distance under the action of the third spring 106b of the same specification. However, since the length of the strong pressure lever 104 is greater than the length of the weak pressure lever 105, and the length of the first gap 104a is less than the length of the second gap 105a, when the strong pressure lever... When the distance of the first gap 104a moved by 104 comes into contact with the pressure module 201, the remaining third spring force is converted into pressure N1 on the pressure module 201. Similarly, when the second power supply 302 is connected to the temporary wiring line P2, the measured value of the pressure module 201 is N2. Therefore, N1 is greater than N2. When fully connected, the strong pressure rod 104 and the weak pressure rod 105 simultaneously come into contact with the pressure module 201, resulting in the value N3. Therefore, N3 > N1 > N2 > 0. Thus, by simply outputting the value to the outside, the four-phase status of the switch can be accurately determined by the state corresponding to different values.

[0048] When it is necessary to keep the first power supply 301 disconnected from the temporary wiring line P1, simply press the opening / closing lever 102e so that the second actuating lever 1021 on one side contacts the inclined side locking block 106d, and squeeze the inclined side locking block 106d to make the strong pressure lever 104 move back a certain distance. When the second actuating lever 1021 descends to the lowest point, the strong pressure lever 104 rebounds a short distance so that the locking groove 106e at the bottom of the inclined side locking block 106d engages with the second actuating lever 1021, and the first arc groove connecting plate 102h and the temporary wiring line P1 are connected. When line P1 reaches its lowest point, the temporary wiring line P1 is no longer in contact with the conductive block 107b and is thus disconnected from the first power supply 301. At this time, the inclined locking block 106d limits the opening and closing rod 102e, preventing the opening and closing rod 102e from rising. The second actuating rod 1021 on one side of the opening and closing rod 102e limits the strong pressure rod 104 at the bottom of the inclined locking block 106d, so that the strong pressure rod 104 is limited and maintains a first gap 104a with the pressure-bearing module 201. Thus, the disconnection between the first power supply 301 and the temporary wiring line P1 is achieved.

[0049] When it is necessary to connect or disconnect the second power supply 302 from the temporary wiring line P2, refer to the above procedure. This allows for the complete connection or disconnection of two sets of temporary lines, as well as the precise connection or disconnection of a single line.

[0050] When it is necessary to set up three or more sets of temporary wiring and monitor them, the modular design of the first double-key adjustment component 102 and the second double-key adjustment component 103 can be expanded to multiple sets, and adapted and installed by pressure rods of different lengths. Thus, different values ​​Nx can be obtained according to the above principle based on different pressure rods. Only by assigning corresponding numbers to different values ​​Nx can the on / off status be remotely determined based on the values.

[0051] In summary, the dual-position switching unit can quickly clamp and fix temporary wiring of two sets of lines and control their on / off states. Furthermore, the dual-position switching unit, combined with the four-phase monitoring unit, can accurately classify and monitor four on / off states of the two sets of lines, promptly detecting operator errors in opening and closing the switches, thus achieving remote monitoring and error prevention. The modularly designed first and second dual-key adjustment components can be expanded to multiple sets to accommodate monitoring of more line wiring, enabling accurate classification and identification of four or even more phase states, suitable for complex wiring environments.
