Description

Technical Field

[0001] This utility model relates to the technical field of power maintenance equipment, and in particular to an emergency power supply system for substations. Background Technology

[0002] During the use of substation equipment, there are sudden situations where faults occur and circuit breakers trip. In such cases, it is often necessary to manually activate the emergency power supply to ensure the continuous operation of the substation equipment. In addition, the emergency power supply consists of multiple battery packs, and the battery packs continuously consume power while operators are troubleshooting and maintaining the substation to identify the cause of the trip and the fault.

[0003] Therefore, it can be seen that, on the one hand, in such emergency power supply, after a trip, the emergency power supply gate needs to be opened manually. The efficiency of manually opening the emergency power supply gate is low, and there is a possibility that the emergency power supply cannot be opened in time, which reduces the timeliness of the emergency power supply response.

[0004] On the other hand, existing technologies lack real-time monitoring of the number of consumed battery packs, which can lead to situations where emergency power supplies are overused or depleted without timely replacement of emergency batteries, thus affecting the normal operation of the entire substation equipment. Utility Model Content

[0005] In view of the above problems, this utility model provides an emergency power supply system for substations, the purpose of which is to improve the response speed of emergency power supply.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An emergency power supply system for a substation is provided, comprising: a chamber; a first circuit breaker controller disposed within the chamber and electrically connected to equipment within the substation; a second circuit breaker controller disposed within the chamber and electrically connected to an emergency battery and equipment within the substation; two circuit breakers disposed on the first and second circuit breakers respectively, for controlling the opening and closing of the first and second circuit breakers; a linkage component rotatably disposed within the chamber; a first and a second lever disposed on the linkage component, respectively located on opposite sides of the rotation center of the linkage component; wherein one end of the first lever is located below the circuit breaker of the first circuit breaker controller for tripping the circuit breaker of the first circuit breaker controller; one end of the second lever is located below the circuit breaker of the second circuit breaker controller for actuating the opening and closing of the circuit breaker of the second circuit breaker controller; and a counting component disposed within the chamber for measuring the amount of battery consumed.

[0008] Furthermore, the system also includes: a first buffer component disposed in the chamber, a piston plate slidably disposed in the first buffer component, a third rod disposed on one side of the piston plate, and a first elastic support component disposed on the other side of the piston plate; one end of the third rod slides against the side of the linkage component away from the first rod.

[0009] Furthermore, the counting component includes: a slide rail disposed within the cavity; a slider slidably disposed within the slide rail; a sensing component disposed within the slide rail, located on one side of the slider; a second elastic support component disposed between the slider and the sensing component; a motor disposed within the cavity; and a counting disk disposed on the output shaft of the motor, used to actuate the sensing component to slide within the slider and press the second elastic support component, thereby periodically triggering the sensing component.

[0010] Furthermore, the system also includes: a first toothed block disposed on the slider; and a second toothed block disposed on the counting disk, the second toothed block being used to actuate the first toothed block.

[0011] Furthermore, the system also includes: a second buffer component disposed within the chamber; a buffer plate slidably disposed within the second buffer component, with a slider connected to one side of the buffer plate, and a buffer chamber formed on the other side of the buffer plate and the inner wall surface of the second buffer component; a first pipe connected at one end to the buffer chamber and at the other end to the outside; a second pipe connected at one end to the buffer chamber and at the other end to the outside; a first one-way valve disposed on the first pipe to allow outside gas to enter the buffer chamber; and a second one-way valve disposed on the second pipe to allow gas in the buffer chamber to exit to the outside.

[0012] Furthermore, the system also includes: a pressure storage component, which is connected to the end of the second pipe away from the buffer chamber, for storing positive pressure; and a third pipe, one end of which is connected to the pressure storage component, and the other end of which is connected to the side of the piston plate in the first buffer component on which the first elastic support component is installed.

[0013] Furthermore, the system also includes: a first abutting rod and a second abutting rod that are installed in contact with each other, the first abutting rod being disposed on the counting disk and the second abutting rod being disposed on the first rod.

[0014] Furthermore, the system also includes a C-shaped buckle, which is installed on the second rod, and the gate block of the second power switch controller is located inside the C-shaped buckle.

[0015] The beneficial effects of this utility model are as follows: when the gate block of the first circuit breaker controller moves downward to press against the first rod, the left side of the linkage component descends and the right side rises, and the second rod moves upward to push the gate block of the second circuit breaker controller upward, thereby opening the emergency power supply and supplying power to the equipment in the substation to ensure the normal operation of the equipment in the substation; there is no need for manual activation of the emergency power supply, which improves the timeliness of emergency power supply activation; it can also record the number of emergency power supply groups used through the counting component, so as to facilitate operators to maintain the tripped equipment and control the maintenance time.

Detailed Implementation

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figure 1 and Figure 2The present application discloses an emergency power supply system for a substation, comprising: a chamber 1; a first circuit breaker controller 2, disposed within the chamber 1 and electrically connected to equipment within the substation; a second circuit breaker controller 3, disposed within the chamber 1 and electrically connected to an emergency battery and equipment within the substation; two circuit breakers 4, respectively disposed on the first circuit breaker controller 2 and the second circuit breaker controller 3, for controlling the opening and closing of the first circuit breaker controller 2 and the second circuit breaker controller 3; a linkage component 5, rotatably disposed within the chamber 1; a first rod 51 and a second rod 512, disposed on the linkage component 5, respectively located on opposite sides of the rotation center of the linkage component 5; wherein, one end of the first rod 51 is located below the circuit breaker 4 of the first circuit breaker controller 2, for tripping the circuit breaker 4 of the first circuit breaker controller 2; one end of the second rod 512 is located below the circuit breaker 4 of the second circuit breaker controller 3, for actuating the opening and closing of the circuit breaker 4 of the second circuit breaker controller 3; and a counting component, disposed within the chamber 1, for measuring the amount of battery consumed.

[0024] In practical use, when the first circuit breaker controller 2 trips, the gate block 4 of the first circuit breaker controller 2 moves downward to press against the first rod 51, the left side of the linkage component 5 moves down and the right side moves up, and the second rod 512 moves upward to push the gate block 4 of the second circuit breaker controller 3 upward, which can open the emergency power supply and supply power to the equipment in the substation to ensure the normal operation of the equipment in the substation; there is no need to manually start the emergency power supply, which improves the timeliness of emergency power supply opening.

[0025] Specifically, the system further includes: a first buffer component 52 disposed in the chamber 1, a piston plate 521 slidably disposed in the first buffer component 52, a third rod 522 disposed on one side of the piston plate 521, and a first elastic support component 531 disposed on the other side of the piston plate 521; one end of the third rod 522 slides against the side of the linkage component 5 away from the first rod 51.

[0026] When the first circuit breaker controller 2 trips, the circuit breaker block 4 of the first circuit breaker controller 2 descends and presses against the first rod 51. The left side of the linkage component 5 descends and can also press the third rod 522 down, driving the piston plate 521 down within the first buffer component 52 and pressing against the first elastic support component 531. The first elastic support component 531 deforms under force and generates a reaction force, which can buffer the piston plate 521 and prevent the circuit breaker block 4 of the first circuit breaker controller 2 from jumping too violently in an instant, which would damage the first circuit breaker controller 2.

[0027] It is worth mentioning that the first elastic support component 531 can be a spring; a roller can also be added to the end of the third rod 522, which can roll to contact one side of the linkage component 5 to reduce wear; the linkage component 5 can be hinged to the inner wall of the chamber 1 by a mounting shaft.

[0028] It is understandable that the lower side of the piston plate 521 can also be filled with hydraulic oil. During the downward movement of the piston plate 521, the hydraulic oil can be squeezed out through the pipeline to the first buffer component 52 to further enhance the buffering effect.

[0029] Specifically, the counting assembly includes: a slide rail 7 disposed within the chamber 1; a slider 71 slidably disposed within the slide rail 7; a sensing component disposed within the slide rail 7, located on one side of the slider 71; a second elastic support component 532 disposed between the slider 71 and the sensing component; a motor 6 disposed within the chamber 1; and a counting disk 61 disposed on the output shaft of the motor 6, used to actuate the sensing component to slide within the slider 71 and press the second elastic support component 532, thereby periodically triggering the sensing component.

[0030] Preferably, the system further includes: a first toothed block disposed on the slider 71; and a second toothed block disposed on the counting disk 61, the second toothed block being used to actuate the first toothed block.

[0031] In practical use, after the emergency power supply is activated, motor 6 starts synchronously. The output shaft of motor 6 drives the counting disk 61 to rotate. During the rotation of the counting disk 61, it periodically drives the second tooth block to move, thereby driving the slider 71 to slide along the slide rail 7, squeezing the second elastic support component 532, and triggering the sensing component. When the sensing component is subjected to force twice, it indicates that the power of a single emergency power supply group is exhausted. It is worth mentioning that each rotation of the counting disk 61 indicates that one emergency power supply group has been used. The number of emergency power supply groups used is recorded so that operators can maintain the tripped equipment and control the maintenance time.

[0032] It is worth mentioning that the second elastic support component 532 can be a spring, and the sensing component can be an existing pressure sensor.

[0033] Reference Figure 3 , Figure 4 and Figure 5 As shown, the system also includes: a first abutting rod and a second abutting rod installed in contact with each other, the first abutting rod being disposed on the counting disk 61 and the second abutting rod being disposed on the first rod 51.

[0034] When the gate block 4 of the first circuit breaker controller 2 does not trip, the first abutting rod and the second abutting rod abut against each other, and the second abutting rod restricts the rotation of the first abutting rod; when the gate block 4 of the first circuit breaker controller 2 trips, the first rod 51 moves downward, so that the second abutting rod makes way for the first abutting rod to allow the counting disk 61 to rotate and count.

[0035] Specifically, the system further includes: a second buffer component 8, disposed within the chamber 1; a buffer plate 81, slidably disposed within the second buffer component 8, with a slider 71 connected to one side of the buffer plate 81, and a buffer chamber formed on the other side of the buffer plate 81 and the inner wall of the second buffer component 8; a first pipe 811, one end connected to the buffer chamber and the other end connected to the outside; a second pipe 812, one end connected to the buffer chamber and the other end connected to the outside; a first one-way valve disposed on the first pipe 811 to allow outside gas to enter the buffer chamber; and a second one-way valve disposed on the second pipe 812 to allow gas in the buffer chamber to exit to the outside.

[0036] In practical use, during the periodic movement of the slider 71 by the counting disk 61, the second elastic support component 532 generates a reaction force that causes the slider 71 to quickly reset. The slider 71 drives the buffer plate 81 to slide along the inner wall of the second buffer component 8. The gas on the left side of the buffer plate 81 is compressed, thereby applying a reaction force to the buffer plate 81, thus preventing the slider 71 from resetting too quickly and causing vibration, and protecting the sensing component.

[0037] In addition, the system also includes: a pressure storage component 9, which is connected to the end of the second pipe 812 away from the buffer chamber and is used to store positive pressure; and a third pipe 813, one end of which is connected to the pressure storage component 9 and the other end of which is connected to the side of the piston plate 521 in the first buffer component 52 on which the first elastic support component 531 is installed.

[0038] When the buffer plate 81 slides to the right along the inner wall of the second buffer component 8, gas is drawn from the outside into the second buffer component 8 through the first pipe 811. When the buffer plate 81 slides to the left along the inner wall of the second buffer component 8, gas is forced into the pressure storage component 9 through the second pipe 812, increasing the pressure value in the pressure storage component 9 and storing positive pressure through the pressure storage component 9.

[0039] After the operator completes the maintenance work on the substation, the pressure in the pressure storage component 9 can be released, and the pressure can be released into the first buffer component 52 through the third pipe 813. This pushes the piston plate 521 to move upward, thereby causing the first rod 51 on the left side of the linkage component 5 to move upward again and push against the gate block 4 of the first circuit breaker controller 2 to close the circuit. This automatically restarts the first circuit breaker controller 2. At the same time, the second circuit breaker controller 3 on the right side does not need to be manually closed, reducing risks and making the operation more convenient.

[0040] Understandably, the hydraulic oil filling the lower side of the piston plate 521 can enter the pressure storage component 9 through the third pipe 813 for temporary storage.

[0041] Preferably, a control valve 10 is provided on the third pipe fitting 813, and the opening and closing of the third pipe fitting 813 is controlled by the control valve 10.

[0042] Preferably, the system further includes a C-shaped buckle 511, which is disposed on the second rod 512, and the gate block 4 of the second power switch controller 3 is located inside the C-shaped buckle 511, so as to ensure that the second rod 512 can normally move the gate block 4 of the second power switch controller 3.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
