[0002] A vacuum interrupter, also known as a vacuum switch tube, is a core component of medium- and high-voltage power switches. Its main function is to quickly extinguish the arc and suppress the current after the medium- and high-voltage circuit cuts off the power through the excellent insulation of the vacuum inside the tube, avoiding accidents and unexpected situations. The contact is a key component in the vacuum interrupter, responsible for making contact with and separating from the current. Therefore, the reaction force characteristics of the contact are crucial for the stable operation of the equipment.

The target gas refers to the ambient gas preset for the contacts of the vacuum interrupter during actual operation, and the target air pressure refers to the ambient air pressure preset for the contacts of the vacuum interrupter at different working stages, ensuring that the reaction force detection of the contacts of the vacuum interrupter is carried out under the ambient gas and ambient air pressure it faces during actual operation. Thus, based on this target gas and this target air pressure, a reaction force detection is performed on the contacts of the vacuum interrupter, and the obtained reaction force detection result is also more in line with the actual working conditions of the contacts of the vacuum interrupter, thereby improving the accuracy and reliability of the reaction force detection result of the contacts of the vacuum interrupter. Since the reaction force detection result of the contacts of the vacuum interrupter can characterize the arc extinguishing effect of the contacts of the vacuum interrupter and the safety of the power equipment, the above method also improves the reliability of the arc extinguishing effect of the contacts of the vacuum interrupter and the safety of the power equipment, reduces the accident risk, and lowers the maintenance cost.

[0048] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0049] A vacuum interrupter, also known as a vacuum switch tube, is a core component of medium- and high-voltage power equipment. Its main function is to quickly extinguish the arc and suppress the current after the medium- and high-voltage circuit cuts off the power through the excellent insulation of the vacuum inside the tube, avoiding accidents and unexpected situations. The contact is a key component in the vacuum interrupter, responsible for making contact with and separating from the current. Therefore, the reaction force characteristic of the contact is not only crucial for the stable operation of the equipment, but also reflects the arc extinguishing effect of the vacuum interrupter.

[0050] The vacuum interrupter contact includes a moving contact and a static contact, as can be seen in Figure 1 , where the static contact is located above and the moving contact is located below. The contact reaction force refers to the force generated on the moving contact and pointing to the static contact when the contact separates. Currently, the detection of the contact reaction force of the vacuum interrupter is usually carried out before the vacuum interrupter leaves the factory. However, in the actual operation of the vacuum interrupter contact, there are many external factors such as ambient air pressure and ambient gas. Under different ambient air pressures or different ambient gases, the contact reaction force of the vacuum interrupter is different. This results in the fact that the reaction force detection result before leaving the factory cannot be used as the reaction force of the vacuum interrupter contact during actual operation. That is, the reaction force detection result before leaving the factory is not accurate and reliable enough because it does not conform to the actual working scenario of the vacuum interrupter contact. Further, the evaluation of the arc extinguishing effect of the vacuum interrupter contact and the safety of medium- and high-voltage power equipment based on the reaction force detection result is also not accurate and reliable enough, and the accident risk is likely to increase, and thus the operation and maintenance cost will also increase.

[0051] The method for detecting the contact reaction force of the vacuum interrupter provided by the embodiments of the present disclosure can be applied to, for example, Figure 1In the application environment shown. Among them, the execution entity can be the control server 102, and the control server 102 is connected to the gas treatment device 104. Specifically, the control server 102 responds to the reaction force detection signal for the vacuum interrupter contact, and controls the preset gas treatment device 104 to inject the target gas into the detection gas chamber where the vacuum interrupter contact is located until the air pressure in the detection gas chamber reaches the target air pressure. Among them, the target gas refers to the ambient gas of the preset vacuum interrupter contact during actual operation, and the target air pressure refers to the ambient air pressure of the preset vacuum interrupter contact at different working stages; the control server 102 performs reaction force detection on the vacuum interrupter contact based on the target gas and the target air pressure, and obtains the reaction force detection result corresponding to the vacuum interrupter contact. Among them, the server 102 can be implemented by an independent server or a server cluster composed of multiple servers.

[0052] In one embodiment, the gas treatment device 104 may further include a vacuum pump and a gas supply and return device. The vacuum pump and the gas supply and return device are both connected to the detection gas chamber. The vacuum pump is used to pump the detection gas chamber until the detection gas chamber is in a vacuum state, and the gas supply and return device is used to inject the target gas into the detection gas chamber in a vacuum state, that is, the vacuum chamber.

[0053] In one embodiment, the control server 102 is also connected to a motion device. The motion device may include a kinetic energy module and a pulling module. The pulling module is fixed to the bottom of the detection gas chamber through a fixing device. The pulling module may further include a transmission device and a cantilever. The kinetic energy module is connected to the transmission device, and the transmission device is connected to the cantilever. The kinetic energy module is used to convert electrical energy into kinetic energy and provide it to the transmission device for the transmission device to drive the cantilever to push or pull the moving contact of the vacuum interrupter upward or downward.

[0054] In one embodiment, the motion device is also connected with a scale. Specifically, a scale is fixed in the vertical direction of the cantilever for measuring the pulling distance of the moving contact of the vacuum interrupter.

[0055] In one embodiment, a distance sensor can be used instead of the scale. Specifically, the distance sensor is connected to the cantilever to collect the pulling distance of the cantilever pulling the moving contact of the vacuum interrupter in real time, improving the accuracy of the pulling distance.

[0056] In one embodiment, the control server 102 may also be connected with a data acquisition module, a data processing and storage module, and a display module. The data acquisition module is used to collect the reaction force detection results in real time and transmit them to the data processing and storage module. The data processing and storage module is used to store the reaction force detection results. Further, it can also draw a reaction force change curve corresponding to the reaction force detection results. This reaction force change curve reflects the change of the reaction force during the movement of the contacts of the vacuum interrupter. The data processing and storage module can send this reaction force change curve to the display module, and the display module can visualize the reaction force change curve, which is convenient for technicians to monitor.

[0057] In one embodiment, as Figure 2 shown, a method for detecting the reaction force of the contacts of a vacuum interrupter is provided. Taking this method applied to Figure 1 the control server 102 therein as an example for illustration, it includes the following steps:

[0058] Step S202, in response to a reaction force detection signal for the contacts of the vacuum interrupter, control a preset gas treatment device to inject a target gas into the detection gas chamber where the contacts of the vacuum interrupter are located until the air pressure in the detection gas chamber reaches the target air pressure.

[0059] Among them, the reaction force detection signal refers to a signal for detecting the reaction force of the contacts of the vacuum interrupter. The target gas refers to the ambient gas of the preset contacts of the vacuum interrupter during actual operation, which can be air, sulfur hexafluoride, etc. These gases are used as the medium for arc extinction in the vacuum interrupter. The target air pressure refers to the ambient air pressure of the preset contacts of the vacuum interrupter at different working stages. Among them, the working stages can be divided according to the working years of the contacts of the vacuum interrupter. For example, from just leaving the factory to the preset working time is one working stage, and from the preset time to shutdown is another working stage. It can also be divided according to the actual situation.

[0060] In one embodiment, the target air pressure includes any one of the standard atmospheric pressure, the rated pressure, and the locking pressure. The standard atmospheric pressure refers to the air pressure value of the contacts of the vacuum interrupter under standard atmosphere. The rated pressure refers to the pressure value required after the contacts of the vacuum interrupter work for a preset time, and the preset time can be set according to the actual situation, such as 10 years, 20 years. The locking pressure refers to the pressure value when the contacts of the vacuum interrupter are shut down. For example, when the product life of the vacuum interrupter reaches 20 years, gas with the rated pressure is filled. After the vacuum interrupter continues to operate for a certain number of years, the pressure will drop slightly and reach the lowest at the locking pressure. When the pressure is lower than the locking pressure, the vacuum interrupter needs to stop operating.

[0061] In one embodiment, controlling the preset gas processing device to inject a target gas into the detection gas chamber where the vacuum interrupter contact is located until the air pressure in the detection gas chamber reaches the target air pressure further includes: if the target air pressure is the standard atmospheric pressure, controlling the gas processing device to inject the target gas into the detection gas chamber where the vacuum interrupter contact is located until the air pressure value in the detection gas chamber reaches the air pressure value under the standard atmosphere.

[0062] If the target air pressure is the rated pressure, controlling the preset gas processing device to inject the target gas into the detection gas chamber where the vacuum interrupter contact is located until the air pressure value in the detection gas chamber reaches the pressure value required after the vacuum interrupter contact operates for a preset time.

[0063] If the target air pressure is the locking pressure, controlling the preset gas processing device to inject the target gas into the detection gas chamber where the vacuum interrupter contact is located until the air pressure value in the detection gas chamber reaches the pressure value when the vacuum interrupter contact is out of operation.

[0064] In one embodiment, the detection gas chamber of the vacuum interrupter contact is a sealed space for simulating the actual working environment of the vacuum interrupter.

[0065] Specifically, the control server can preset the target gas and the target air pressure to be detected in each round of reaction force detection in advance. If a reaction force detection signal for the vacuum interrupter contact is received, the current ambient air pressure and the current ambient gas of the vacuum interrupter contact can be detected first, that is, the current air pressure and gas in the detection gas chamber where the vacuum interrupter contact is located. If both the current ambient air pressure of the vacuum interrupter contact and the target air pressure preset for this round of detection, as well as the current ambient gas of the vacuum interrupter contact and the target gas preset for this round of detection are different, the control server sends an instruction to the gas processing device to instruct the gas processing device to inject the target gas into the detection gas chamber until the air pressure in the detection gas chamber reaches the target air pressure.

[0066] In one embodiment, before performing the reaction force detection on the vacuum interrupter contact, it is necessary to determine that the moving contact and the static contact of the vacuum interrupter are in the just-closed state, which is convenient for subsequent reaction force detection.

[0067] Step S204, based on the target gas and the target air pressure, perform a reaction force detection on the vacuum interrupter contact to obtain the reaction force detection result corresponding to the vacuum interrupter contact.

[0068] Among them, the reaction force detection result refers to the movement reaction force generated on the moving contact of the vacuum interrupter and pointing to the static contact of the vacuum interrupter when the vacuum interrupter contact separates.

[0069] Specifically, the control server controls the gas processing device to inject the target gas into the detection gas chamber until the air pressure in the detection gas chamber reaches the target air pressure. After that, a motion instruction can be sent to a preset motion device to instruct the motion device to control the movement of the vacuum interrupter contact, so as to obtain the movement pulling force generated during the movement of the vacuum interrupter contact. Since the movement pulling force and the movement reaction force are a pair of interaction forces, the movement reaction force corresponding to the moving contact of the vacuum interrupter can be directly determined according to the movement pulling force. In this way, the obtained reaction force detection result conforms to various actual working scenarios of the vacuum interrupter contact, improving the reliability and accuracy of the reaction force detection of the vacuum interrupter contact.

[0070] In this embodiment, considering that the vacuum interrupter will extinguish arcs under various gases and air pressures during actual operation, when the above method receives a reaction force detection signal for the vacuum interrupter contact, it first controls a preset gas processing device to inject the target gas into the detection gas chamber where the vacuum interrupter contact is located until the air pressure in the detection gas chamber reaches the target air pressure. The target gas refers to the ambient gas of the preset vacuum interrupter contact during actual operation, and the target air pressure refers to the ambient air pressure of the preset vacuum interrupter contact at different working stages, ensuring that the reaction force detection of the vacuum interrupter contact is carried out under the ambient gas and ambient air pressure it faces during actual operation. Thus, based on the target gas and the target air pressure, the reaction force of the vacuum interrupter contact is detected, and the obtained reaction force detection result also conforms more to the actual working conditions of the vacuum interrupter contact, thereby improving the accuracy and reliability of the reaction force detection result of the vacuum interrupter contact. Since the reaction force detection result of the vacuum interrupter contact can characterize the arc extinguishing effect of the vacuum interrupter contact and the safety of the power equipment, the above method also improves the reliability of the arc extinguishing effect of the vacuum interrupter contact and the safety of the power equipment, reduces the accident risk, and lowers the maintenance cost.

[0071] In one embodiment, as Figure 3 shown, the controlling the preset gas processing device to inject the target gas into the detection gas chamber where the vacuum interrupter contact is located until the air pressure in the detection gas chamber reaches the target air pressure in response to a reaction force detection signal for the vacuum interrupter contact includes:

[0072] Step S302, in response to a reaction force detection signal for the vacuum interrupter contact, obtain the current ambient air pressure and the current ambient gas of the vacuum interrupter contact.

[0073] Wherein, the current ambient air pressure refers to the current air pressure value in the detection gas chamber where the vacuum interrupter contact is located, and the current ambient gas refers to the current gas in the detection gas chamber where the vacuum interrupter contact is located.

[0074] Specifically, when the control server receives the reaction force detection signal for the contacts of the vacuum interrupter, it first obtains the current air pressure and the current gas in the detection gas chamber where the contacts of the vacuum interrupter are located, so as to conduct subsequent comparison of the consistency of air pressure values and comparison of the consistency of gas types.

[0075] In one embodiment, a pressure sensor may be provided in the detection gas chamber, and the pressure sensor can be used to monitor the air pressure value in the detection gas chamber in real time.

[0076] In one embodiment, a gas detector may also be provided in the detection gas chamber, and the gas detector can be used to monitor the gas type in the detection gas chamber in real time.

[0077] Step S304: Compare the current ambient air pressure with the target air pressure to obtain the comparison result of the air pressure value consistency, and compare the current ambient gas with the target gas to obtain the comparison result of the gas type consistency.

[0078] Among them, the comparison result of the air pressure value consistency is used to characterize whether the air pressure value of the current ambient air pressure of the contacts of the vacuum interrupter is consistent with the air pressure value of the target air pressure, and the comparison result of the gas type consistency is used to characterize whether the gas type of the current ambient gas of the contacts of the vacuum interrupter is consistent with the gas type of the target gas. The gas type can be air, sulfur hexafluoride, etc.

[0079] Specifically, there can be multiple reaction force detections for the contacts of the vacuum interrupter. For each reaction force detection, a set of gas pressure combinations can be set, that is, a combination of the target gas and the target air pressure, such as air and rated pressure, air and standard atmospheric pressure, air and closing pressure, sulfur hexafluoride and standard atmospheric pressure, sulfur hexafluoride and rated pressure, sulfur hexafluoride and closing pressure. The current air pressure value in the detection gas chamber where the contacts of the vacuum interrupter are located is detected, and this air pressure value is compared with the air pressure value of the target air pressure to determine whether they are consistent, so as to obtain the comparison result of the air pressure value consistency. Similarly, the current gas type in the detection gas chamber where the contacts of the vacuum interrupter are located is detected, and this gas type is compared with the gas type of the target gas to determine whether they are consistent, so as to obtain the comparison result of the gas type consistency.

[0080] Step S306: If both the comparison result of the air pressure value consistency and the comparison result of the gas type consistency are inconsistent, control the preset gas treatment equipment to inject the target gas into the detection gas chamber where the contacts of the vacuum interrupter are located until the air pressure in the detection gas chamber reaches the target air pressure.

[0081] Specifically, if both the comparison result of air pressure value consistency and the comparison result of gas type consistency are inconsistent, that is, the current air pressure value in the detection gas chamber where the vacuum interrupter contact is located is inconsistent with the target air pressure value, and the current gas type in the detection gas chamber where the vacuum interrupter contact is located is also inconsistent with the target gas type, it is necessary to control the gas treatment device to inject the target gas into the detection gas chamber until the air pressure in the detection gas chamber reaches the target air pressure.

[0082] In an embodiment, if the comparison result of air pressure value consistency is consistent and the comparison result of gas type consistency is consistent, that is, the current air pressure value in the detection gas chamber where the vacuum interrupter contact is located is the same as the target air pressure value, and the current gas type in the detection gas chamber where the vacuum interrupter contact is located is also the same as the target gas type, the reaction force of the vacuum interrupter contact can be directly detected to obtain the reaction force detection result corresponding to the vacuum interrupter contact.

[0083] In an embodiment, if the comparison result of air pressure value consistency is consistent and the comparison result of gas type consistency is inconsistent, that is, the current air pressure value in the detection gas chamber where the vacuum interrupter contact is located is the same as the target air pressure value, but the current gas type in the detection gas chamber where the vacuum interrupter contact is located is different from the target gas type, the air pressure in the detection gas chamber is kept unchanged, and the gas treatment device is controlled to change the gas in the detection gas chamber until there is no other gas except the target gas in the detection gas chamber.

[0084] In an embodiment, if the comparison result of air pressure value consistency is inconsistent and the comparison result of gas type consistency is consistent, that is, the current air pressure value in the detection gas chamber where the vacuum interrupter contact is located is different from the target air pressure value, but the current gas type in the detection gas chamber where the vacuum interrupter contact is located is the same as the target gas type, the air pressure in the detection gas chamber can be directly adjusted to the target air pressure.

[0085] In this embodiment, by comparing the current ambient air pressure of the vacuum interrupter contact with the target air pressure for air pressure value consistency, and comparing the current ambient gas of the vacuum interrupter contact with the target gas for gas type consistency, it is determined whether to inject gas into the detection gas chamber based on the comparison results of air pressure value consistency and gas type consistency, which improves the accuracy and efficiency of gas injection, and thus improves the accuracy and efficiency of subsequent reaction force detection.

[0086] In an embodiment, as Figure 4 shown, controlling the preset gas treatment device to inject the target gas into the detection gas chamber where the vacuum interrupter contact is located includes:

[0087] Step S402, sending a gas extraction instruction to the gas treatment device.

[0088] Among them, the air extraction instruction is used to instruct the gas processing device to extract air from the detection chamber. Further, the air extraction instruction is used to instruct the vacuum pump in the gas processor to extract air from the detection chamber.

[0089] Specifically, when the control server detects that the current ambient gas in the detection chamber where the contacts of the vacuum interrupter are located is inconsistent with the target gas, it sends an air extraction instruction to the gas processing device. When the gas processing device receives this air extraction instruction, it first controls the vacuum pump to extract air from the detection chamber to discharge the current gas in the detection chamber, obtaining a vacuum chamber, i.e., a vacuum gas chamber.

[0090] Step S404: When it is detected that the detection chamber is a vacuum gas chamber, send an air injection instruction to the gas processing device.

[0091] Among them, the air injection instruction is used to instruct the gas processing device to inject the target gas into the vacuum gas chamber. Further, the air injection instruction is used to instruct the gas supply and return device in the gas processor to inject the target gas into the vacuum gas chamber.

[0092] Specifically, when the control server detects that the detection chamber is in a vacuum state, it sends an air injection instruction to the gas processing device again. When the gas processing device receives this air injection instruction, it sends the instruction to the gas supply and return device to instruct the gas supply and return device to inject the target gas into the vacuum gas chamber.

[0093] In this embodiment, by extracting and replacing the gas in the detection chamber, it is ensured that the gas in the detection chamber is the target gas for subsequent reaction force detection, ensuring that the gas in the detection chamber is accurate, thereby improving the accuracy of the reaction force detection.

[0094] In one embodiment, as Figure 5 shown, based on the target gas and the target air pressure, performing a reaction force detection on the contacts of the vacuum interrupter to obtain the reaction force detection result corresponding to the contacts of the vacuum interrupter, including:

[0095] Step S502: Obtain the preset movement speed of the moving contact of the vacuum interrupter.

[0096] Among them, the preset movement speed refers to the movement speed when performing the reaction force detection on the moving contact of the vacuum interrupter that is preset in advance. For example, it can be set to 0.8 m / s (meters per second).

[0097] Step S504: Based on the target gas and the target air pressure, send a movement instruction to a preset movement device.

[0098] Among them, the motion instruction is used to instruct the motion device to pull down the moving contact of the vacuum interrupter at a preset motion speed. Since the moving and static contacts of the vacuum interrupter are in the just-closed state before the reaction force detection, it is necessary to pull down the moving contact to separate the moving and static contacts.

[0099] Specifically, when the detection air chamber of the vacuum interrupter contact is under the target gas and target air pressure, the reaction force detection of the vacuum interrupter contact can be performed, that is, the control server sends a motion instruction to the motion device. After receiving the motion instruction, the motion device can send the motion instruction to the kinetic energy module in the motion device. After receiving the motion instruction, the kinetic energy module generates electric energy and converts the electric energy into kinetic energy to provide it to the transmission device. After the transmission device obtains the kinetic energy, it can drive the cantilever to pull up and down. When performing the reaction force detection, the cantilever can pull down the moving contact of the vacuum interrupter at a preset motion speed to separate the moving and static contacts. When performing the next round of reaction force detection, the cantilever can push up the moving contact of the vacuum interrupter to make the moving and static contacts in the closed state again.

[0100] Step S506: Obtain the motion pulling force generated by the moving contact of the vacuum interrupter during the motion process, and determine the motion reaction force corresponding to the moving contact of the vacuum interrupter according to the motion pulling force.

[0101] Among them, the motion pulling force refers to the pulling force generated when the cantilever pulls down the moving contact of the vacuum interrupter. The motion pulling force and the motion reaction force are a pair of interaction forces and are the same. Therefore, when the motion pulling force is obtained, the motion reaction force can be directly determined.

[0102] Specifically, during the process of the cantilever pulling down the moving contact of the vacuum interrupter at a preset motion speed, it is detected whether the pulling distance of the moving contact of the vacuum interrupter is equal to the preset motion distance. If it is equal, the motion pulling force generated by the moving contact of the vacuum interrupter during the motion process is calculated, and thus the motion reaction force corresponding to the moving contact of the vacuum interrupter is determined according to the motion pulling force.

[0103] In this embodiment, the moving contact of the vacuum interrupter is pulled based on the preset motion speed, so as to obtain the motion pulling force of the moving contact of the vacuum interrupter, and then the motion reaction force of the moving contact of the vacuum interrupter can be directly obtained. Thus, the reaction force detection result can be obtained simply and quickly.

[0104] In one embodiment, before the step of obtaining the motion pulling force generated by the moving contact of the vacuum interrupter during the motion process, it further includes: reading the pulling distance of the moving contact of the vacuum interrupter through the scale; obtaining the preset motion distance of the moving contact of the vacuum interrupter; the obtaining the motion pulling force generated by the vacuum interrupter contact during the motion process includes: if it is detected that the pulling distance is equal to the preset motion distance, obtaining the motion pulling force generated by the moving contact of the vacuum interrupter during the motion process.

[0105] Among them, the pulling distance refers to the distance that the cantilever pulls down the moving contact of the vacuum interrupter. The preset movement distance refers to the movement distance when the moving contact of the vacuum interrupter conducts the reaction force detection, which can be set to the conventional distance when the contacts of the vacuum interrupter are working, or can be set according to the actual situation.

[0106] Specifically, the pulling distance can be read through a scale. The scale has the characteristic of being convenient, which can improve the convenience of the entire reaction force detection. In one embodiment, a distance sensor can also be used to read the pulling distance. After reading the pulling distance of the moving contact of the vacuum interrupter, it is detected whether the pulling distance reaches the preset movement distance during the reaction force detection. If the preset movement distance is reached, the movement pulling force can be calculated according to the pulling distance, the preset movement speed, and the weight of the moving contact of the vacuum interrupter, so as to obtain the movement reaction force of the moving contact of the vacuum interrupter.

[0107] In one embodiment, a force sensor can also be arranged at the cantilever, and the force sensor can measure the movement reaction force of the moving contact of the vacuum interrupter in real time.

[0108] In this embodiment, when it is detected that the pulling distance of the moving contact of the vacuum interrupter is equal to the preset movement distance, the movement pulling force is calculated based on the pulling distance and the preset movement speed, which improves the accuracy of the movement pulling force, thereby improving the accuracy of the movement reaction force, and further improving the accuracy of the reaction force detection.

[0109] In one embodiment, when the current gas is sulfur hexafluoride and the target air pressure is the rated pressure, the reaction force detection of the vacuum interrupter contacts can include: the control server responds to the reaction force detection signal for the vacuum interrupter contacts, and obtains the current ambient air pressure and the current ambient gas of the vacuum interrupter contacts. If it is detected that the current ambient air pressure is not equal to the rated pressure and the current ambient gas is not sulfur hexafluoride, the control vacuum pump evacuates the detection gas chamber where the vacuum interrupter contacts are located until the detection gas chamber is in a vacuum state, and then controls the gas supply and return device to inject sulfur hexafluoride into the gas chamber in the vacuum state until the air pressure in the gas chamber reaches the rated pressure. At this time, the control server sends a movement instruction to the movement device to instruct the movement device to pull down the moving contact of the vacuum interrupter at the preset movement speed. If it is detected that the pulling distance of the moving contact of the vacuum interrupter is equal to the preset movement distance, the movement pulling force generated by the moving contact of the vacuum interrupter during the movement is obtained, so as to obtain the movement reaction force of the vacuum interrupter contacts, that is, the reaction force detection result.

[0110] In this embodiment, when a reaction force detection signal for the contact of the vacuum interrupter is received, sulfur hexafluoride is injected into the detection gas chamber until the gas pressure in the detection gas chamber reaches the rated pressure, ensuring that the reaction force detection of the contact of the vacuum interrupter is carried out under the ambient gas and ambient air pressure it faces during actual operation. Thus, under the detection environment of sulfur hexafluoride and the rated pressure, the reaction force of the contact of the vacuum interrupter is detected, and the obtained reaction force detection result is also more in line with the actual working conditions of the contact of the vacuum interrupter, thereby improving the accuracy and reliability of the reaction force detection result of the contact of the vacuum interrupter. Since the reaction force detection result of the contact of the vacuum interrupter can characterize the arc extinguishing effect of the contact of the vacuum interrupter and the safety of the power equipment, the above method also improves the reliability of the arc extinguishing effect of the contact of the vacuum interrupter and the safety of the power equipment, reduces the accident risk, and lowers the maintenance cost.
