Description

Technical Field

[0001] This invention relates to the field of switch isolation technology, specifically to a switch isolation device, an air switch isolation method, and a system. Background Technology

[0002] An air switch, also known as an air circuit breaker, is a type of circuit breaker. It is a switch that automatically disconnects when the current in the circuit exceeds the rated current. Air switches are a very important electrical appliance in low-voltage power distribution networks and electric drive systems, integrating control and multiple protection functions. In addition to connecting and disconnecting circuits, it can also protect against short circuits, severe overloads, and undervoltage in circuits or electrical equipment, and can also be used for infrequent starting of motors.

[0003] The commonly used method to prevent accidental activation of air switches is to seal the operating air switch with red insulating tape, or to design a switch with its own anti-accidental activation structure. However, this method has shortcomings: after the tape is removed, the adhesive residue sticks to the air switch, which may cause accidental opening or closing. There is also insufficient force to force the seal. Switches with their own anti-accidental activation structure occupy a lot of space and cannot be flexibly isolated and unlocked during operation, which cannot guarantee the effective control of the air switch. Summary of the Invention

[0004] The technical problem this invention aims to solve is that traditional methods for preventing accidental operation of air switches suffer from insufficient forced sealing force, inflexible isolation and unlocking, and inability to guarantee effective control of the air switches. This invention provides a switch isolation device, air switch isolation method, and system that can manage multiple switches specifically, designate specific switches for isolation, and offers convenience. The isolation component ensures sufficient sealing force, and one switch isolation device can manage multiple switches, saving space. Furthermore, it allows for adjustment of the switches to be isolated as needed. This solution also generates an adjustment strategy based on the air switch's operating mode data, and the switch isolation device adjusts its operating state according to the adjustment strategy, promptly isolating or unlocking the corresponding switches under different operating conditions.

[0005] This invention is achieved through the following technical solution:

[0006] This solution provides a switch isolation device, including:

[0007] An isolator, the isolator being used to isolate one or more switches;

[0008] A movable locking element is used to move the isolating element to the position where the isolating switch needs to be applied; the movable locking element is also used to lock the isolating element; the isolating element is mounted on the movable locking element.

[0009] A fixing element is used to secure a movable locking element to one or more switches; the movable locking element is mounted on the fixing element.

[0010] The working principle of this solution is as follows: To prevent accidental activation, traditional methods include designing switches with built-in anti-accidental activation structures or sealing the switches with red insulating tape. However, switches with anti-accidental activation structures are relatively large and unsuitable for switch cabinets. Using insulating tape for sealing provides insufficient sealing strength, failing to guarantee effective control of the safety circuit breaker. Therefore, this solution designs a switch isolation device, primarily suitable for various switch components installed in electrical cabinets. The switch isolation device, through the cooperation of movable locking components, fixed components, and isolation components, can selectively manage multiple switches and designate specific isolation points, offering convenience. The isolation components ensure sealing strength, and one switch isolation device can manage multiple switches, saving space.

[0011] A further optimized solution is that the movable locking component includes:

[0012] Lock the slider, slider, and slide rail;

[0013] The locking slider includes a first locking slider and a second locking slider;

[0014] The first locking slider, the second locking slider, and the slider are fixed sequentially on the slide rail, and all three can move along the slide rail.

[0015] The first locking slider is provided with a first locking element for locking the first slider onto the slide rail;

[0016] The second locking slider is provided with a second locking element for locking the second slider onto the slide rail;

[0017] The slide rail is fixedly mounted on the fixing member, and the isolation member is fixedly mounted on the sliding member.

[0018] A further optimized solution also includes a control module;

[0019] The control module is connected to the first locking element and the second locking element;

[0020] The control module is used to lock the first locking slider in the first designated position of the slide rail according to the instruction via the first locking member;

[0021] The control module is also used to lock the second locking slider in the second designated position of the slide rail according to the instruction via the second locking member.

[0022] A further optimized solution is that the isolation component includes a first connector, a second connector, and a blocking component that are integrally connected in sequence; the first connector is fixedly installed on the sliding component, and the blocking component is used to prevent the switch from operating.

[0023] A further optimized solution is that the first and second locking components are electromagnetic locks, with a lock hole matching the electromagnetic lock on the slide rail. The electromagnetic lock extends and passes through the lock hole according to the command, fixing and locking the first or second locking sliding component.

[0024] When the first and second locking components are in the open state, the first locking slider, the second locking slider, and the slider can slide freely along the slide rail. When it is necessary to isolate a switch, move the slider to the corresponding position and make the first and second locking sliders close to the left and right sides of the slider; lock the first and second locking components. At this time, the first and second locking sliders are locked, and the slider between the first and second locking sliders is also passively locked, realizing the isolation of the switch at the corresponding position of the slider. When it is necessary to change the isolated switch, open the first and second locking components, move the first locking slider, the second locking slider, and the slider to the corresponding position and relock.

[0025] In the specific implementation process, the first locking slider, the second locking slider, and the slider are all sliders. The first locking element and the second locking element are electromagnetic locks installed on the first locking slider and the second locking slider, respectively. Locking holes matching the electromagnetic locks are provided on the slide rail. The electromagnetic locks extend and pass through the locking holes according to instructions, fixing and locking the first locking slider or the second locking slider. The length of the guide rail is determined based on the length of the air switch bar on the protection panel, and locking holes are drilled on the guide rail according to the positions of the air switches. The spacing between adjacent locking holes is set as needed.

[0026] This solution also provides an air switch isolation method, based on the above-mentioned switch isolation device, the method comprising the following steps:

[0027] Obtain the basic data of the circuit breaker; the basic data includes: the circuit breaker's operating mode data and location data;

[0028] The switch isolation device is assembled based on the location data;

[0029] Based on the aforementioned basic data, a risk analysis of malfunction is performed on each air switch to generate an isolation strategy. The operation state of the switch isolation device is automatically adjusted according to the isolation strategy. The operation state includes: the position of the first sliding member, the second sliding member, and the third sliding member, and the open and locked states of the first locking member and the second locking member.

[0030] The working principle of this solution: Traditional air switch isolation processes rely on manual isolation or unlocking by personnel. Different personnel are responsible for different switches under different work modes such as maintenance, safety work, and equipment modification. When it is necessary to unlock overlapping switches, multiple personnel are required, resulting in a waste of human resources. This solution generates an adjustment strategy based on the air switch's working mode data. The switch isolation device adjusts its operating state according to the adjustment strategy, promptly isolating or unlocking the corresponding switches under different operating conditions.

[0031] In addition, even when the device is unlocked, the switch at the corresponding position of the isolator still has the effect of preventing accidental activation. During operation, staff can move the isolator to the switch position that needs to be isolated in real time as needed, and the switch isolation device also brings convenience to the operation process.

[0032] A further optimized solution is that assembling the switch isolation device based on the location data includes the following method:

[0033] Number the circuit breakers in the circuit breaker bar according to their arrangement order;

[0034] Prefabricated switch isolation device: The first set of lock holes is opened on the slide rail according to the position of each air switch, and the second set of lock holes is opened between two adjacent lock holes in the first set of lock holes; the numbering of the first set of lock holes is consistent with the numbering of the air switches;

[0035] Locking sliders are installed on the slide rail at intervals, with locking sliders at both ends of the slide rail;

[0036] Install the prefabricated switch isolation device on the air switch bar.

[0037] A further optimized solution involves generating an isolation strategy based on the aforementioned basic data by performing a malfunction risk analysis on each air switch, including the following method:

[0038] Obtain the location, network topology, and operating mode of each circuit breaker;

[0039] Extract the equipment to be operated and its location from the working mode;

[0040] Screening risk switch sets: Based on the location data, screen the location risk air switch sets for each proposed operating equipment; based on the associated network topology, screen the operation risk air switch sets for each proposed operating equipment; use the combination of the location risk air switch sets and the operation risk air switch sets as the risk switch set;

[0041] The isolation strategy is obtained by deduplicating elements in the risk switch set.

[0042] A further optimized solution is that the screening of the risk switch set includes the following methods:

[0043] With the current work equipment as the center, construct a sphere A with radius r. All air switches located within sphere A constitute the location risk air switch set of the current work equipment.

[0044] Simulation is performed based on the network topology diagram. The current equipment to be operated is operated in the simulation software, and each air switch is debugged and simulated. The air switches with electrical faults in the simulation results are screened out to form the set of air switches with operational risks for the current equipment to be operated.

[0045] In generating the isolation strategy, this solution not only considers switches that are close to the equipment to be operated and have the risk of accidental operation from a location perspective, but also switches that may cause electrical faults after accidental operation from an operational perspective, thus reducing the risk of switch accidental operation from multiple dimensions.

[0046] This solution also provides an air switch isolation system, which is used to implement the above-mentioned air switch isolation method. The system includes:

[0047] The data acquisition module is used to acquire basic data of the circuit breaker; the basic data includes: the circuit breaker's operating mode data and location data;

[0048] Assembly module, used to assemble the switch isolation device based on the position data;

[0049] The adjustment module is used to perform a risk analysis of malfunction of each air switch based on the basic data to generate an isolation strategy, and automatically adjust the operation state of the switch isolation device according to the isolation strategy; the operation state includes: the position of the first sliding member, the second sliding member and the third sliding member, and the open and locked states of the first locking member and the second locking member.

[0050] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0051] 1. The present invention provides a switch isolation device. A set of switch isolation devices can manage multiple switches in a targeted manner and designate some switches to be isolated by the cooperation of movable locking parts, fixed parts and isolation parts, which is convenient; the isolation parts can ensure the sealing force, and a set of switch isolation devices can manage multiple switches in a targeted manner, saving space, and can also adjust the switches that need to be isolated as needed.

[0052] 2. The present invention provides an air switch isolation method and system, which generates an adjustment strategy based on the air switch's operating mode data, and the switch isolation device adjusts its operating state according to the adjustment strategy, so as to isolate or unlock the corresponding switch in a timely manner under different operating conditions.

[0053] 3. In the process of generating the isolation strategy, this solution not only considers switches that are close to the equipment to be operated and have the risk of accidental operation from the perspective of location, but also considers switches that have the risk of electrical fault after accidental operation from the perspective of operation, thereby reducing the risk of switch accidental operation from multiple dimensions.

Detailed Implementation

[0062] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0063] During secondary operations of relay protection, especially when the outage maintenance device and the operating device are in the same cabinet, there is a risk of accidentally touching the operating circuit breaker, causing the operating device to lose power or malfunction (alarm), which will adversely affect the normal and reliable operation of the power grid. Currently, the most common method to prevent accidental contact with the circuit breaker is to seal it with red insulating tape. However, this method has several drawbacks: firstly, the sealing force is insufficient and it can be accidentally opened; secondly, accidental tape detachment can cause the circuit breaker's safety measures to fail; and thirdly, when removing the tape, the tape may stick to the circuit breaker, causing it to close accidentally.

[0064] Example 1

[0065] This embodiment provides a switch isolation device, such as Figure 1 As shown, it includes:

[0066] Isolator 1, the isolator being used to isolate one or more switches;

[0067] The movable locking element 2 is used to move the isolating element 1 to the position where the isolating switch 3 needs to be disconnected. The movable locking element 2 is also used to lock the isolating element 1. The isolating element 1 is mounted on the movable locking element 2.

[0068] A fixing element is used to fix the movable locking element 2 to one or more switches; the movable locking element 2 is mounted on the fixing element.

[0069] To prevent accidental activation, traditional methods include designing switches with built-in anti-accidental activation structures or sealing the switches with red insulating tape. However, switches with anti-accidental activation structures are large and unsuitable for switch cabinets. Using insulating tape provides insufficient sealing strength, failing to guarantee effective control of the safety circuit breaker. Therefore, this solution designs an independent switch isolation device. One switch isolation device, through the cooperation of movable locking components, fixed components, and isolation components, can selectively manage multiple switches and designate specific isolation points, offering convenience. The isolation components ensure sealing strength, and one switch isolation device can selectively manage multiple switches, saving space and allowing adjustment of the switches to be isolated as needed.

[0070] like Figure 2 As shown, the movable locking element 2 includes:

[0071] Locking slider, slider 23 and slide rail 24;

[0072] The locking slider includes a first locking slider and a second locking slider;

[0073] The first locking slider 21, the second locking slider 22 and the slider 23 are fixed on the slide rail 24 in sequence, and the first locking slider, the second locking slider and the slider 23 can all move along the slide rail;

[0074] The first locking slider is provided with a first locking element for locking the first slider onto the slide rail;

[0075] The second locking slider is provided with a second locking element for locking the second slider onto the slide rail;

[0076] The slide rail is fixedly mounted on the fixing member, and the isolation member is fixedly mounted on the sliding member.

[0077] It also includes a control module;

[0078] The control module is connected to the first locking element and the second locking element;

[0079] The control module is used to lock the first locking slider in the first designated position of the slide rail according to the instruction via the first locking member;

[0080] The control module is also used to lock the second locking slider in the second designated position of the slide rail according to the instruction via the second locking member.

[0081] like Figure 3 As shown, the isolation member 1 includes a first connector 11, a second connector 12, and a blocking member 13 that are integrally connected in sequence; the first connector 11 is fixedly installed on the sliding member 23, and the blocking member 13 is used to prevent the switch 3 from operating.

[0082] The first and second locking components are electromagnetic locks. A lock hole 25 matching the electromagnetic lock is provided on the slide rail. The electromagnetic lock extends and passes through the lock hole 25 according to the command, and fixes the first locking slide or the second locking slide in place.

[0083] When the first and second locking components are in the open state, the first locking slider, the second locking slider, and the slider can slide freely along the slide rail. When it is necessary to isolate a switch, move the slider to the corresponding position and make the first and second locking sliders close to the left and right sides of the slider; lock the first and second locking components. At this time, the first and second locking sliders are locked, and the slider between the first and second locking sliders is also passively locked, realizing the isolation of the switch at the corresponding position of the slider. When it is necessary to change the isolated switch, open the first and second locking components, move the first locking slider, the second locking slider, and the slider to the corresponding position and relock.

[0084] In the specific implementation process, the first locking slider, the second locking slider, and the slider are all sliders. The first locking element and the second locking element are electromagnetic locks installed on the first locking slider and the second locking slider, respectively. Locking holes matching the electromagnetic locks are provided on the slide rail. The electromagnetic locks extend and pass through the locking holes according to instructions, fixing and locking the first locking slider or the second locking slider. The length of the guide rail is determined based on the length of the air switch bar on the protection panel, and locking holes are drilled on the guide rail according to the positions of the air switches. The distance between two adjacent locking holes is P.

[0085] Example 2

[0086] This embodiment provides an air switch isolation method, implemented based on a switch isolation device described in Embodiment 1, such as... Figure 4 As shown, the method includes the following steps:

[0087] Step 1: Obtain the basic data of the circuit breaker; the basic data includes: the circuit breaker's operating mode data and location data;

[0088] Step 2: Assemble the switch isolation device based on the location data; specifically including the following methods:

[0089] S1, Number each air switch in the air switch bar according to the arrangement order;

[0090] S2, Prefabricated switch isolation device: The first set of lock holes is opened on the slide rail according to the position of each air switch, and the second set of lock holes is opened between two adjacent lock holes in the first set of lock holes; the number of the first set of lock holes is consistent with the number of the air switches.

[0091] S3, locking sliders and sliders are installed on the slide rail at intervals, and both ends of the slide rail are locking sliders;

[0092] S4. Install the prefabricated switch isolation device on the air switch bar.

[0093] Step 3: Based on the basic data, perform a malfunction risk analysis on each air switch to generate an isolation strategy, and automatically adjust the operation state of the switch isolation device according to the isolation strategy; the operation state includes: the position of the first sliding member, the second sliding member and the third sliding member, and the open and locked states of the first locking member and the second locking member.

[0094] The method for generating an isolation strategy based on the aforementioned basic data and performing a malfunction risk analysis on each air switch includes:

[0095] T1, obtain the location, associated network topology, and operating mode of each air switch; the associated network topology includes the upper-level circuit topology and lower-level circuit topology of the air switch, and the operating mode includes the operation type, the equipment to be operated and its location, and the operation status.

[0096] T2 extracts the proposed operating equipment and its location from the working mode;

[0097] T3, Filter the risk switch set: Based on the location data, filter the location risk air switch set for each proposed operating equipment; based on the associated network topology, filter the operation risk air switch set for each proposed operating equipment; use the combination of the location risk air switch set and the operation risk air switch set as the risk switch set;

[0098] In the specific implementation process, this step includes the following methods:

[0099] With the current work equipment as the center, construct a sphere A with radius r. All air switches located within sphere A constitute the location risk air switch set of the current work equipment. The radius r is set based on historical work data or by analyzing the range of human movement.

[0100] Simulations are performed based on the interconnected network topology. The current equipment to be operated is run in the simulation software, and each circuit breaker is tested and simulated. Circuit breakers with electrical faults identified in the simulation results are selected, forming a set of circuit breakers with operational risks for the current equipment to be operated. These electrical faults include open-circuit faults, short-circuit faults, and grounding faults.

[0101] T4 is an isolation strategy obtained by deduplicating elements in the risk switch set.

[0102] The working principle of this solution: Traditional air switch isolation processes rely on manual isolation or unlocking by personnel. Different personnel are responsible for different switches under different work modes such as maintenance, safety work, and equipment modification. When it is necessary to unlock overlapping switches, multiple personnel are required, resulting in a waste of human resources. Therefore, this solution generates an adjustment strategy based on the air switch's working mode data. The switch isolation device adjusts its operating state according to the adjustment strategy, promptly isolating or unlocking the corresponding switches under different operating conditions.

[0103] In addition, even when the device is unlocked, the switch at the corresponding position of the isolator still has the effect of preventing accidental activation. During operation, staff can move the isolator to the switch position that needs to be isolated in real time as needed, and the switch isolation device also brings convenience to the operation process.

[0104] Example 3

[0105] This embodiment provides an air switch isolation system, which is used to implement the air switch isolation method described in Embodiment 2. The system includes:

[0106] The data acquisition module is used to acquire basic data of the circuit breaker; the basic data includes: the circuit breaker's operating mode data and location data;

[0107] Assembly module, used to assemble the switch isolation device based on the position data;

[0108] The adjustment module is used to perform a risk analysis of malfunction of each air switch based on the basic data to generate an isolation strategy, and automatically adjust the operation state of the switch isolation device according to the isolation strategy; the operation state includes: the position of the first sliding member, the second sliding member and the third sliding member, and the open and locked states of the first locking member and the second locking member.

[0109] like Figure 5 As shown, in this embodiment, the switch isolation device is applied in the protection cabinet. The first row in the protection cabinet is the air switch bar, and the switch isolation device is installed on the air switch bar. The first row is the relay protection equipment, and the third row is other switches. In the secondary operation mode of relay protection, especially when the power outage maintenance device and the operating device are in the same cabinet, there is a possibility of accidentally touching the operating air switch, which may cause the operating device to lose power or malfunction (alarm), which will have an adverse impact on the normal and reliable operation of the power grid.

[0110] Based on the basic data, a risk analysis of malfunction is performed on each circuit breaker to generate the following isolation strategy:

[0111] The protection cabinet contains the signal circuits of the outgoing switch terminal boxes and the operation panel of control devices A and B. Simulations show that in the maintenance mode of control device B, accidental operation of the air switches in the signal circuits of the outgoing switch terminal boxes and the operation panel of control device A may cause DC grounding. Therefore, air switches A1, A2, A3, ... in the signal circuits of the outgoing switch terminal boxes and the operation panel of control device A are included in the set of air switches with operational risks.

[0112] In the maintenance mode of the measurement and control device B, the work equipment B1 is required. With equipment B1 as the center, a sphere with radius r is constructed. The air switches located in the sphere A include: air switch C1, air switch A2, air switch A3, ...; the air switches located in the sphere A are included in the location risk air switch set.

[0113] Finally, the set of all working equipment location risk air switches and the combined set of risk air switches are taken as the risk switch set. Air switches A2, A3, etc. in the risk switch set are screened out to obtain the adjustment strategy; each isolator is aligned and locked to each air switch in the adjustment strategy.

[0114] This solution generates an adjustment strategy based on the working mode data of the air switch. The switch isolation device adjusts its operating state according to the adjustment strategy, and promptly isolates or unlocks the corresponding switch under different working conditions. Furthermore, in the unlocked state, the switch at the corresponding position of the isolation component still has the effect of preventing accidental operation. During operation, the operator can move the isolation component to the switch position that needs to be isolated in real time as needed, which also brings convenience to the operation process.

[0115] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
