Description

Technical Field

[0001] This application relates to the field of line protection, and more specifically, to a substation line protection device. Background Technology

[0002] Substation line protection devices are core equipment in power systems used to ensure the safe and stable operation of transmission and distribution lines. By monitoring electrical quantities such as current and voltage in real time, they identify abnormalities such as overload, short circuit, and grounding faults. Once a problem occurs in the line, the line protection device sends a trip signal and performs the actual disconnection operation through the circuit breaker, effectively isolating the fault and preventing the accident from escalating.

[0003] However, the existing substation line protection devices still have the following shortcomings in use: Most existing line protection devices are fixed by bolts. Although bolt fixing can stably fix the line protection device, it is necessary to disassemble the line protection device when it malfunctions or needs to be maintained for regular maintenance. Without special tools, it is impossible to disassemble the line protection device by bolt connection, and the bolt disassembly process is time-consuming and laborious. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a substation line protection device, which aims to improve the problem that when the line protection device malfunctions or is scheduled for maintenance, it needs to be disassembled. The line protection device is connected by bolts, and without special tools, it is impossible to disassemble the line protection device. Furthermore, the bolt disassembly process is time-consuming and labor-intensive.

[0005] This application provides a substation line protection device, including a base and a line protector. A fixing mechanism is provided on the top of the base for fixing the line protector to one side of the base. A moving mechanism is provided inside the base for moving the line protector. The base is used with bolts to connect to the installation location of the line protector inside the substation, such as a wall. Then the line protector is fixed to one side of the base. When the line protector is disassembled, it is not necessary to disassemble the base. The fixing mechanism includes two sets of mounting components, both of which are connected to one side of the line protector. The top of each mounting component has a positioning hole, and one side of the base has two sets of mounting slots. The mounting components are movably inserted into the mounting slots.

[0006] In one specific implementation, the top of the base is connected to two sets of housings, the inside of the housings is slidably connected to a first sliding member, the bottom of the first sliding member is connected to a positioning member, and the positioning member passes through the base and is movably inserted into the inside of a positioning hole.

[0007] In the above implementation process, by setting the positioning member, the mounting member can be limited inside the mounting groove by inserting the positioning member into the positioning hole, and the line protector can be fixed to one side of the base to complete the installation of the line protector. Furthermore, by controlling the movement of the first sliding member, the positioning member can be moved.

[0008] In one specific implementation, a first inclined surface is provided on one side of the positioning member.

[0009] In the above implementation process, by setting the first inclined surface, when the mounting part is inserted into the mounting groove, one side of the mounting part will squeeze the first inclined surface, causing the positioning part and the first sliding part to move upward.

[0010] In one specific implementation, the top of the first sliding member is connected to a first vertical rod, the other end of the first vertical rod passes through the housing and is connected to a horizontal plate, a spring is sleeved on the outer surface of the first vertical rod, and a handle is connected to the top of the horizontal plate.

[0011] In the above implementation process, by setting the handle, the first vertical rod can be moved upward by pulling the handle, which in turn moves the first sliding member upward, causing the positioning member to disengage from the positioning hole, thus allowing the mounting member to be removed from the inside of the mounting slot. By setting the spring, when the mounting member is inserted into the inside of the mounting slot, the positioning member and the first sliding member are moved upward to compress the spring. When the positioning hole moves to below the positioning member, the spring releases its elastic potential energy, causing the positioning member to be inserted into the inside of the positioning hole.

[0012] In one specific implementation, the moving mechanism includes a support plate connected to one side of the base.

[0013] In the above implementation process, by setting up a support plate, a supporting force can be provided when the mounting part is removed from the mounting slot, which can prevent the line protector from falling off.

[0014] In one specific implementation, the base has a cavity inside, and a third sliding member is slidably connected inside the cavity.

[0015] In the above implementation process, the cavity allows the third slider to slide up and down inside the cavity.

[0016] In one specific implementation, the top of the third sliding member is connected to a second vertical rod, one end of which passes through the base and is connected to a connecting plate, the connecting plate being connected to one side of the horizontal plate.

[0017] In the above implementation process, by setting the connecting plate, when the horizontal plate moves upward, it can drive the connecting plate to move upward, drive the second vertical rod to move upward, and make the third sliding member slide upward inside the cavity.

[0018] In one specific implementation, the cavity is provided with a second sliding member, one end of which penetrates through the base. The top of the second sliding member has two sets of sliding grooves, and the inner wall of the cavity is connected to two sets of sliders, which are slidably connected inside the sliding grooves.

[0019] In the above implementation process, by setting the second sliding member, the circuit protector can be pushed to move outward a certain distance on the support plate by sliding the second sliding member outward inside the cavity. By setting the slider and the groove, the second sliding member can slide horizontally.

[0020] In one specific implementation, a second inclined surface is provided on one side of the second slider.

[0021] In the above process, by setting the second inclined surface, the operator can pull the handle upwards, causing the first and third sliding parts to slide upwards. The first sliding part moves the positioning part. After the positioning part completely leaves the positioning hole, the positioning part's restriction on the mounting part is released. At this time, the third sliding part contacts the second inclined surface. The operator continues to pull the handle upwards, and one side of the third sliding part presses against the second inclined surface, causing the second sliding part to slide outwards inside the cavity. This pushes the line protector to move a certain distance outwards from the top of the support plate, causing the mounting part to detach from the mounting groove. The positioning hole is no longer located below the positioning part. Then the operator releases the handle, and the spring causes the positioning part to reset. The positioning part can no longer restrict the mounting part, and the operator can then remove the line protector from the top of the support plate with both hands.

[0022] In one specific implementation, a groove is provided on one side of the second slider.

[0023] In the above implementation process, the groove is designed so that the second vertical rod can pass through the groove.

[0024] Compared with the prior art, the beneficial effects of this application are as follows: Through the setting of the fixing mechanism and the moving mechanism, when the operator pulls the handle upwards, the first and second vertical rods move upwards simultaneously, causing the first and third sliding parts to slide upwards. The first sliding part moves the positioning part. After the positioning part completely leaves the positioning hole, the positioning part's restriction on the mounting part is released. At this time, the third sliding part contacts the second inclined surface. When the operator continues to pull the handle upwards, one side of the third sliding part presses against the second inclined surface, causing the second sliding part to slide outwards inside the cavity, pushing the line protector to move a certain distance outwards from the top of the support plate, causing the mounting part to detach from the mounting groove, and the positioning hole is no longer located below the positioning part. Then, the operator releases the handle, and the spring causes the positioning part to reset. The positioning part can no longer restrict the mounting part, and the operator can then remove the line protector from the top of the support plate with both hands. This solves the problem that when the line protection device malfunctions or is under regular maintenance, it needs to be disassembled. Using bolt connections, it is impossible to disassemble the line protection device without special tools, and the bolt disassembly process is time-consuming and laborious.

Detailed Implementation

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0029] Please see Figure 1 and Figure 2 This application provides a substation line protection device, including a base 1 and a line protector 4.

[0030] Please see Figure 1 The base 1 is provided with a fixing mechanism 2 for fixing the line protector 4 to one side of the base 1. The base 1 is provided with a moving mechanism 3 for moving the line protector 4. The base 1 is used with bolts to connect the installation point of the line protector 4 inside the substation, such as the wall. Then the line protector 4 is fixed to one side of the base 1. When the line protector 4 is disassembled, it is not necessary to disassemble the base 1.

[0031] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The fixing mechanism 2 includes two sets of mounting parts 201. Both sets of mounting parts 201 are connected to one side of the line protector 4. The top of the mounting part 201 is provided with a positioning hole 202. The base 1 is provided with two sets of mounting grooves 203 on one side. The mounting part 201 is movably inserted into the inside of the mounting groove 203.

[0032] In the specific setup, two sets of housings 206 are connected to the top of the base 1. A first sliding member 207 is slidably connected inside the housing 206. A positioning member 208 is connected to the bottom of the first sliding member 207. The positioning member 208 passes through the base 1 and is movably inserted into the positioning hole 202. By setting the positioning member 208, the mounting member 201 can be limited inside the mounting groove 203 by inserting the positioning member 208 into the positioning hole 202, and the line protector 4 can be fixed to one side of the base 1, thus completing the installation of the line protector 4. Furthermore, by controlling the movement of the first sliding member 207, the positioning member 208 can be moved.

[0033] In a specific configuration, a first inclined surface 209 is provided on one side of the positioning member 208. When the mounting member 201 is inserted into the mounting groove 203, one side of the mounting member 201 will press against the first inclined surface 209, causing the positioning member 208 and the first sliding member 207 to move upward.

[0034] In a specific configuration, the top of the first sliding member 207 is connected to a first vertical rod 2010. The other end of the first vertical rod 2010 passes through the housing 206 and is connected to a horizontal plate 204. A spring 2011 is sleeved on the outer surface of the first vertical rod 2010. A handle 205 is connected to the top of the horizontal plate 204. By pulling the handle 205, the first vertical rod 2010 can be moved upward, which in turn moves the first sliding member 207 upward, causing the positioning member 208 to disengage from the positioning hole 202. This allows the mounting member 201 to be removed from the mounting groove 203. The spring 2011 compresses the positioning member 208 and the first sliding member 207 when the mounting member 201 is inserted into the mounting groove 203. When the positioning hole 202 moves below the positioning member 208, the spring 2011 releases its elastic potential energy, causing the positioning member 208 to insert into the positioning hole 202.

[0035] In a specific configuration, the moving mechanism 3 includes a support plate 301, which is connected to one side of the base 1. The support plate 301 provides support when the mounting part 201 is removed from the mounting groove 203, thus preventing the line protector 4 from falling off.

[0036] In a specific configuration, a cavity 306 is provided inside the base 1, and a third sliding member 305 is slidably connected inside the cavity 306. The cavity 306 enables the third sliding member 305 to slide up and down inside the cavity 306.

[0037] In a specific configuration, the top of the third sliding member 305 is connected to a second vertical rod 304. One end of the second vertical rod 304 passes through the base 1 and is connected to a connecting plate 303. The connecting plate 303 is connected to one side of the horizontal plate 204. By setting the connecting plate 303, when the horizontal plate 204 moves upward, it can drive the connecting plate 303 to move upward, thereby driving the second vertical rod 304 to move upward, so that the third sliding member 305 slides upward inside the cavity 306.

[0038] In a specific configuration, the cavity 306 is provided with a second sliding member 302. One end of the second sliding member 302 penetrates the base 1. Two sets of sliding grooves 309 are provided on the top of the second sliding member 302. Two sets of sliders 3010 are connected to the inner wall of the cavity 306. The sliders 3010 are slidably connected inside the sliding grooves 309. The second sliding member 302 can be driven to slide outward inside the cavity 306, thereby pushing the circuit protector 4 to move outward a certain distance above the support plate 301. The sliders 3010 and the sliding grooves 309 enable the second sliding member 302 to slide horizontally.

[0039] In a specific configuration, a second inclined surface 307 is provided on one side of the second sliding member 302. This inclined surface 307 allows the operator to pull the handle 205 upwards, causing the first and third sliding members 207 and 305 to slide upwards. The first sliding member 207 moves the positioning member 208. Once the positioning member 208 is completely away from the positioning hole 202, its restriction on the mounting member 201 is released. At this point, the third sliding member 305 contacts the second inclined surface 307. If the operator continues to pull the handle 205 upwards, the third sliding member 305... The three sliding members 305 press against the second inclined surface 307 on one side, causing the second sliding member 302 to slide outward inside the cavity 306. This pushes the line protector 4 to move outward a certain distance above the support plate 301, causing the mounting part 201 to disengage from the mounting groove 203. The positioning hole 202 is no longer located below the positioning member 208. Then, the operator releases the hand, and the spring 2011 drives the positioning member 208 to reset. The positioning member 208 can no longer limit the mounting part 201, and the operator can then remove the line protector 4 from above the support plate 301 with both hands.

[0040] In a specific configuration, a groove 308 is provided on one side of the second sliding member 302, wherein the second vertical rod 304 can pass through the groove 308 through the groove 308.

[0041] The working principle of the substation line protection device is as follows: When using the substation line protection device, the operator can pull the handle 205 upwards, causing the first vertical rod 2010 and the second vertical rod 304 to move upwards simultaneously. This causes the first sliding member 207 and the third sliding member 305 to slide upwards. The first sliding member 207 moves the positioning member 208. After the positioning member 208 completely leaves the positioning hole 202, the limiting effect of the positioning member 208 on the mounting member 201 is released. At this time, the third sliding member 305 contacts the second inclined surface 307. If the operator continues to pull the handle 205 upwards, one side of the third sliding member 305 presses against the second inclined surface 307, causing the second sliding member 302 to move within the cavity 306. The circuit protector 4 slides outward from the inside, pushing it to move a certain distance outward from the top of the support plate 301. This causes the mounting part 201 to disengage from the inside of the mounting groove 203, and the positioning hole 202 is no longer located below the positioning part 208. Then, the operator releases the spring 2011, which drives the positioning part 208 to reset. The positioning part 208 can no longer limit the mounting part 201, and the operator can then remove the circuit protector 4 from the top of the support plate 301 with both hands. This solves the problem that when the circuit protection device malfunctions or needs to be disassembled for regular maintenance, it is impossible to disassemble the circuit protection device without special tools due to the bolt connection method, and the bolt disassembly process is time-consuming and laborious.

[0042] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
