AI Technical Summary
When the existing three-position switch is grounded and closed in an environmentally friendly gas environment, a high-temperature electric arc is easily generated when the moving end of the switch approaches the grounding plate, causing the switch and the grounding plate to melt and stick together, making it impossible to open again and rendering the switch unusable.
The first pre-breakdown structure and the second pre-breakdown structure are set in the barrier system so that the barrier body and the grounding plate generate a pre-breakdown arc during the grounding closing process, so as to avoid breakdown of the barrier body and the grounding plate and prevent ablation. The moving end speed of the barrier and the grounding closing time are measured by a laser probe to ensure the reliability of the barrier system.
It effectively prevents the spacer and grounding plate from melting and sticking together during the grounding closing process, ensuring that the spacer system can work normally and improving the number of live grounding closing times and test accuracy of the spacer.

Description

[0002] Environmentally friendly alternatives to SF6, a strong greenhouse gas, have become a research hotspot in the power industry. Replacing SF6 gas in traditional ring main units with environmentally friendly gas is an effective solution to reduce SF6 gas usage. However, the insulation and arc-extinguishing properties of environmentally friendly gas are inferior to those of SF6 gas, and the current three-position switchgear's grounding and closing short-circuit current capability in an environmentally friendly gas environment is insufficient. During the current live grounding and closing process of the switchgear, when the moving end of the switchgear approaches the grounding plate, the voltage on the switchgear breaks down the gap between the grounding plates, generating a high-temperature arc. This melts the moving end of the switchgear and the grounding plate, causing them to stick together and become unable to be opened again, rendering the switchgear unusable. Summary of the Invention

[0017] To address the aforementioned issues, this application provides a testing device for a barrier system, used to measure the grounding and closing short-circuit current of the barrier system of this application. The testing device for the barrier system includes: a charging power supply, a charging switch, a capacitor, an inductor, a second current probe, a discharge switch, a discharge resistor, and a third signal acquisition unit.

[0018] To address the aforementioned problems, this application provides a testing method for a blade separator system, which is applied to the testing device for the blade separator system of this application. The testing method for the blade separator system includes the following steps: adjusting the capacitance and rated voltage of the capacitor, setting the charging switch to the ON position, setting the blade separator system to the OFF position, setting the discharging switch to the OFF position, and adjusting the charging power supply to charge the capacitor; after the capacitor is fully charged, turning on the charging switch, closing the grounding of the blade separator system, reading the current waveform collected by the second current probe in the third signal acquisition unit, and recording the erosion and adhesion of the blade separator system; after the test, closing the discharging switch to discharge the capacitor.
[0019] To address the aforementioned problems, this application provides a method for adjusting a blade separation system, comprising the following steps: obtaining the output voltage of a first DC generator at a certain value...

The grounding-closing pre-breakdown time of the disconnector system at a voltage value within kV is calculated. The current waveform at that voltage value is integrated from time t to the grounding-closing pre-breakdown time of the disconnector system at that voltage value. This integral is recorded as the charge transfer amount at that voltage value. The output voltage of the first DC generator is then obtained. Multiple charge transfer quantities corresponding to multiple voltage values within a kV range; based on the output voltage of the first DC generator at... Based on multiple charge transfer values corresponding to various voltage values within kV and the ablation and adhesion status of the separator system, the critical charge transfer value for non-adhesion of the separator system is obtained; according to the critical charge transfer value and the output voltage of the first DC generator, The current waveform at kV is obtained to obtain the current waveform of the separator system.

If the pre-breakdown time under kV voltage is less than or equal to the pre-breakdown time limit, then the blade separator system is qualified.
[0020] If not, the blade separation system is defective. This can be achieved by increasing at least one of the following: increasing the moving end speed of the blade body; increasing the curvature of the surface of the first pre-penetration structure (12) away from the hinge end (1101); increasing the curvature of the surface of the first pre-penetration structure (12) away from the blade plate (111); increasing the curvature of the surface of the second pre-penetration structure (23) away from the base plate (21); and increasing the curvature of the surface of the second pre-penetration structure (23) near the grounding plate (22). The pre-breakdown time at kV voltage is less than the pre-breakdown time limit.
[0021] The advantages of this application are: by setting two first pre-breakdown structures on the blade body and setting second pre-breakdown structures on both sides of the grounding plate, the pre-breakdown arc generated during the grounding closing process of the blade body and the grounding plate breaks down the first and second pre-breakdown structures, preventing the blade body and the grounding plate from being broken down, and avoiding the phenomenon that the blade body and the grounding plate cannot be opened and reused after being burned by the blade body and the grounding plate.
[0022] In this application, any one of the first pre-breakdown structures and any one of the second pre-breakdown structures are spaced apart. When the pre-breakdown arc melts the first and second pre-breakdown structures, the first and second pre-breakdown structures will not stick together, thus avoiding the phenomenon that the partition system cannot be opened and used again.

[0043] The preferred embodiments of this application are described in detail below with reference to the accompanying drawings to fully introduce the technical content of this application to those skilled in the art, to demonstrate that this application can be implemented, and to make the disclosed technical content of this application clearer, so that those skilled in the art can more easily understand how to implement this application. However, this application can be embodied in many different forms of embodiments, and the protection scope of this application is not limited to the embodiments mentioned herein. The description of the embodiments below is not intended to limit the scope of this application.
[0044] The directional terms used in this application, such as "up", "down", "front", "back", "left", "right", "inside", "outside", and "side", are only for the directions shown in the accompanying drawings. The directional terms used herein are for the purpose of explaining and illustrating this application, and not for limiting the scope of protection of this application.
[0045] In the accompanying drawings, components with the same structure are indicated by the same numerical designation, and components with similar structures or functions are indicated by similar numerical designations. Furthermore, for ease of understanding and description, the dimensions and thicknesses of each component shown in the drawings are arbitrary, and this application does not limit the dimensions and thicknesses of each component.
[0046] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a spacer system 100. The spacer system 100 includes: a substrate, a spacer 1 rotatably connected to the substrate, and a grounding contact 2 fixedly connected to the substrate.
[0047] like Figure 1 , Figure 2 and Figure 3 As shown, the separator 1 includes: a separator body 11 and two first pre-penetration structures 12.
[0048] The partition body 11 has a hinged end 1101 and a moving end 1102. The hinged end 1101 is rotatably connected to the substrate. The partition body 11 includes two partition plates 111 arranged opposite to each other.
[0049] The two first pre-penetration structures 12 are both disposed on the moving end 1102 of the partition body 11, and the two first pre-penetration structures 12 respectively cover the surface of one partition plate 111 away from the other partition plate 111.
[0050] The grounding contact 2 includes a base plate 21, a grounding piece 22, and two second pre-breakdown structures 23.
[0051] The base plate 21 has intersecting first direction M and second direction N. In this embodiment, the base plate 21 extends along the first direction M. The thickness direction of the base plate 21 is parallel to the second direction N.
[0052] The two second pre-breakdown structures 23 are located on opposite sides of the grounding plate 22 in the first direction M, and the grounding plate 22 and the two second pre-breakdown structures 23 are located on the same side of the base plate 21 in the second direction N. Specifically, the base plate 21 is fixedly connected to the substrate on one side in the second direction N, and the grounding plate 22 and the two second pre-breakdown structures 23 are located on the side of the base plate 21 away from the substrate in the second direction N.
[0053] like Figure 3 As shown, when the barrier system 100 is in a grounded state, the moving end 1102 of the barrier body 11 overlaps with the grounding plate 22, and the two barrier plates 111 overlap on both sides of the grounding plate 22 in the first direction M. Two first pre-breakdown structures 12 are located between one barrier plate 111 and one second pre-breakdown structure 23, with any one first pre-breakdown structure 12 and any one second pre-breakdown structure 23 spaced apart. By setting two first pre-breakdown structures on the barrier body and second pre-breakdown structures on both sides of the grounding plate, the pre-breakdown arc generated during the grounding closing process of the barrier body and the grounding plate breaks down the first and second pre-breakdown structures, preventing breakdown of the barrier body and the grounding plate. This avoids the burning of the barrier body and the grounding plate, preventing the barrier body and the grounding plate from becoming unusable after overlap.
[0054] In some embodiments, the outer edge of the first pre-breakdown structure 12 on the side away from the hinge end 1101 protrudes beyond the outer edge of the partition plate 111 on the side away from the hinge end 1101. During the energized grounding closing process of the partition body 11, the gap between the first pre-breakdown structure 12 and the second pre-breakdown structure 23 on the partition body 11 first breaks down to generate a high-temperature arc, and then the partition body 11 and the grounding plate 22 are connected without an arc to complete the grounding closing, so that there is no ablation between the partition body 11 and the grounding plate 22 and it does not affect the current flow.
[0055] In some embodiments, the grounding plate 22 and the two second pre-breakdown structures 23 both extend along the second direction N, and the dimensions of the two second pre-breakdown structures 23 in the second direction N are both larger than the dimensions of the grounding plate 22 in the second direction N. During the energized grounding closing process of the blade body 11, the first pre-breakdown structure 12 on the outer side of the moving end 1102 of the blade body 11 first approaches the second pre-breakdown structure 23. The voltage of the first pre-breakdown structure 12 on the blade body 11 first breaks down the gap between the second pre-breakdown structure 23, generating a high-temperature arc. The arc ablates and melts the first pre-breakdown structure 12 and the second pre-breakdown structure 23 on the outer side of the moving end 1102 of the blade body 11. When it approaches the grounding plate 22 again, the blade body 11 and the grounding plate 23... There is no pressure difference between the grounding plates 22, so no electric arc will be generated. There is no high-temperature electric arc erosion at the contact position between the moving end 1102 of the blade body 11 and the grounding plate 22, so they will not stick together. Furthermore, there is a gap between the first pre-breakdown structure 12 and the second pre-breakdown structure 23 on the outer side of the moving end 1102 of the blade body 11, so they will not stick together due to melting. In effect, the arcing point does not overlap, and the overlapping point does not ignite. This ensures that the blade body 11 can be separated again after being energized and grounded, ensuring the normal operation of the switch.
[0056] In some embodiments, the surface of the first pre-penetration structure 12 near the hinge end 1101 is a plane, the surface of the first pre-penetration structure 12 away from the hinge end 1101 is a curved surface, the surface of the first pre-penetration structure 12 near the partition plate 111 is a plane, and the surface of the first pre-penetration structure 12 away from the partition plate 111 is a curved surface.
[0057] In some embodiments, the surface of the second pre-breakdown structure 23 near the base plate 21 is a plane, the surface of the second pre-breakdown structure 23 away from the base plate 21 is a curved surface, the surface of the second pre-breakdown structure 23 near the grounding plate 22 is a curved surface, and the surface of the second pre-breakdown structure 23 away from the grounding plate 22 is a plane.
[0058] In some embodiments, the materials of the first pre-breakdown structure 12 and the second pre-breakdown structure 23 include metals or alloys. Specifically, the first pre-breakdown structure 12 and the second pre-breakdown structure 23 can be made of high-temperature resistant and ablation-resistant metals or alloys. In this embodiment, a copper-tungsten alloy is used to make the first pre-breakdown structure 12 and the second pre-breakdown structure 23. This can increase the number of times the barrier system can be switched on and off during energization.
[0059] In some embodiments, the dimensions of the first pre-breakdown structure 12 and the second pre-breakdown structure 23 in the first direction M can be increased, the curvature of the surface of the first pre-breakdown structure 12 away from the hinge end 1101 can be increased, the curvature of the surface of the first pre-breakdown structure 12 away from the blade plate 111 can be increased, the curvature of the surface of the second pre-breakdown structure 23 away from the base plate 21 can be increased, and the curvature of the surface of the second pre-breakdown structure 23 near the grounding plate 22 can be increased. This reduces the distance between the first pre-breakdown structure 12 and the second pre-breakdown structure 23 when breakdown occurs, shortens the high-temperature arcing time, reduces ablation, and increases the number of times the blade plate is switched on and off with the ground.
[0060] like Figure 4 As shown, this embodiment also provides a test device 200 for a partition system, which is used to measure the movement speed of the moving end 1102 of the partition body 11 of the partition system 100 of this application. The test device for the partition system includes a laser probe 201, a transmission line 202, a data acquisition unit 203 and a data processor 204 connected in sequence.
[0061] The laser probe 201 is configured to correspond to the moving end 1102 of the partition body 11 of the partition system 100. The laser probe 201 is used to acquire the displacement data of the moving end 1102 of the partition body 11 and transmit it to the data acquisition unit 203 through the transmission line 202. The data processor 204 calculates the displacement data in the data acquisition unit 203 to obtain the movement speed of the moving end of the partition body.
[0062] Traditional testing devices for spacer systems calculate the speed of the moving end of the spacer by measuring the rotational angular velocity of the drive shaft of the operating structure. However, because the drive shaft and the spacer are connected by other structural components, machining and installation gaps between these components can cause deviations in the calculation, leading to inaccurate results. In contrast to traditional spacer system testing devices, this embodiment directly measures the speed of the moving end 1102 of the spacer body 11 using a laser probe, accurately measuring the grounding and closing speed of the moving end 1102 of the spacer body 11.
[0063] like Figure 5 and Figure 6 As shown, this application also provides a test device for a barrier system, which is used to measure the grounding-closing pre-breakdown time of the barrier system 100 of this application; the test device for the barrier system 100 includes a first test circuit 300 and a second test circuit 400.
[0064] like Figure 5 As shown, the first test circuit 300 includes: a first power supply 301, a first resistor 302, a first voltage probe 303, a second voltage probe 304, a first signal acquisition unit 305, a first partition operation structure 306, and a first partition system 1001.
[0065] like Figure 5 As shown, one end of the first power supply 301 is connected to the moving end 1102 of the partition body 11 of the first partition system 1001, and the other end of the first power supply 301 is connected to the first resistor 302. The other end of the first resistor 302 is connected to the base plate 21 of the grounding contact 2 of the first partition system 1001.

However, the time difference between the grounding closing of the two-phase disconnectors is only in the microsecond range. By taking the closing time of one phase disconnector as the reference and measuring the closing time of the other phase disconnector or the expected breakdown time under DC voltage, the pre-breakdown time can be accurately obtained.

The testing method for the blade separator system includes the following steps: adjusting the capacitance and rated voltage of capacitor 503, setting the charging switch 502 to the closed position, setting the blade separator system to the open position, setting the discharging switch 506 to the open position, and adjusting the charging power supply 501 to charge capacitor 503; after capacitor 503 is fully charged, turning on the charging switch 502, closing the grounding of the blade separator system, reading the current waveform collected by the second current probe 505 in the third signal acquisition unit 508, and recording the erosion and adhesion of the blade separator system 100; after the test, closing the discharging switch 506 to discharge capacitor 503.
[0076] This application provides a method for adjusting a partition system, which includes the following steps: obtaining the output voltage of a first DC generator 401 between 0 and...

The grounding-closing pre-breakdown time of the disconnector system at a voltage value within kV is calculated by integrating the current waveform at that voltage value from time 0 to the grounding-closing pre-breakdown time of the disconnector system at that voltage value. This integral is recorded as the charge transfer amount at that voltage value. The output voltage of the first DC generator 401 is then obtained from 0 to... Multiple charge transfer quantities corresponding to multiple voltage values within a kV range; based on the output voltage of the first DC generator 401 from 0 to... Based on multiple charge transfer values corresponding to various voltage values within kV and the ablation and adhesion status of the separator system, the critical charge transfer value for non-adhesion of the separator system is obtained; according to the critical charge transfer value and the output voltage of the first DC generator 401, the critical charge transfer value for non-adhesion of the separator system is obtained; The current waveform at kV is obtained to obtain the current waveform of the separator system. The pre-breakdown time limit for non-adhesion under kV voltage; determining the condition of the blade system. If the pre-breakdown time at kV voltage is less than or equal to the pre-breakdown time limit, then the blade separator system is qualified; otherwise, the blade separator system is unqualified. This is achieved by increasing at least one of the following: increasing the moving end speed of the blade separator body; increasing the curvature of the surface of the first pre-breakdown structure (12) away from the hinge end (1101); increasing the curvature of the surface of the first pre-breakdown structure (12) away from the blade plate (111); increasing the curvature of the surface of the second pre-breakdown structure (23) away from the base plate (21); and increasing the curvature of the surface of the second pre-breakdown structure (23) near the grounding plate (22). The pre-breakdown time at kV voltage is less than the pre-breakdown time limit.
[0077] Traditionally, the design of a 100° grounding-off switch system requires testing at a testing station using a short-circuit generator to ensure it passes. If it fails, the system is redesigned and retested until it passes. This design process is somewhat haphazard and the testing costs are high. Furthermore, during the short-circuit generator test, the switch system withstands AC line voltage. If the line voltage amplitude is small and the pre-breakdown time is short during a particular grounding-off switch test, the test may pass. However, if the same switch system experiences a larger line voltage amplitude and longer pre-breakdown time during a subsequent test, the test may fail. This suggests a possibility of the short-circuit generator system passing by chance. This application is based on DC... The kV test, or AC line voltage peak test, represents the most stringent operating condition. An LC oscillation circuit is used to obtain the pre-breakdown time limit that passes the test. The test circuit is simple and does not require on-site testing at a test station. A first DC generator 401 is then used to test the pre-breakdown time of the isolation system 100. By continuously optimizing the curvature and moving-end speed of the isolation system, an isolation system with a pre-breakdown time limit less than the specified limit is ultimately obtained. This isolation system can then pass the grounding-closing test. The design objective is clear, and optimization and verification are simple.
