[0002] In the field of high and low voltage power distribution, in order to achieve safe and efficient power distribution, a distribution cabinet is usually used, that is, a distribution device used for power distribution, control, metering and cable connection in the power supply system. As an important component of the distribution cabinet, the switch of the distribution cabinet is widely used. For example, it is used in the unit drawer of the distribution cabinet to facilitate the operation of the distribution switch by the operator. At present, the high-voltage distribution cabinet generally used in power supply bureaus and substations is connected to the low-voltage distribution cabinet from the low-voltage side after the voltage is reduced by the transformer, and the low-voltage distribution cabinet is then connected to the distribution board, control box and switch box of each power user.

[0003] The switches in high and low voltage distribution cabinets are generally knife switches, which need to be opened and closed manually. Sparks will appear when the knife is opened. Especially in some high-power distribution cabinets, operators may be injured by electric sparks when opening the knife, which is very dangerous and poses a safety hazard.

[0054] Embodiment 1:

[0055] At present, in the field of high and low voltage power distribution, the distribution cabinet generally includes a cabinet body, a cabinet door and a distribution switch. The cabinet body and the cabinet door are rotatably connected at one end and detachably connected at the other end, which is convenient for operators to open or close the cabinet door. The distribution switch is arranged in the cabinet body. The existing distribution switch is a knife switch, which needs to be opened or closed directly or indirectly by tools. Electric sparks will appear during the opening and closing process of the knife switch, which may easily cause harm to the operator and pose certain safety hazards.

[0056] In order to solve the above problems, Figure 1 and Figure 2As shown, this embodiment provides a distribution switch, which includes a shell 10, a pressing mechanism 20, a switch mechanism 30 and a knife switch 40. The pressing mechanism 20 is slidably arranged on one side of the shell 10. The switch mechanism 30 includes a driven component 31 and a switch component 32. One end of the driven component 31 abuts against the other side of the shell 10, and the other end can be driven by the pressing mechanism 20. The switch component 32 is connected to the driven component 31. When the pressing mechanism 20 is pressed or released and a relative displacement occurs, the driven component 31 can be driven, so that the driven component 31 pushes the switch component 32 to perform reciprocating linear motion; and the knife switch 40 is arranged on one side of the switch component 32, so that when the switch component 32 performs linear reciprocating motion, the knife switch 40 follows the movement of the switch component 32 to turn on or off the power supply, thereby realizing the opening and closing of the power supply.

[0057] Through the above structure, when turning the power on or off, the operator presses or releases the pressing mechanism 20, so that the driven component 31 is driven to push the switch component 32 to make a linear reciprocating motion, thereby pushing the knife switch 40 to turn on or off the corresponding power supply, thereby realizing the opening and closing of the corresponding power supply, without the operator directly contacting the knife switch 40, thereby improving the safety of the operator's operation.

[0058] In this embodiment, if Figure 1 As shown, the housing 10 is a frame-type structure, which is convenient for installing other parts. Specifically, the housing 10 includes a U-shaped frame 11 and a fixing plate 12 fixedly connected thereto, the pressing mechanism 20 is slidably arranged on the fixing plate 12, one end of the driven component 31 abuts against the bottom plate of the U-shaped frame 11, and the other end can be driven by the pressing mechanism 20, the switch component 32 is connected to the driven component 31 and is located outside the side wall of the U-shaped frame 11, and can perform linear reciprocating motion with the movement of the driven component 31.

[0059] In this embodiment, if Figure 1 As shown, the pressing mechanism 20 includes a first guide member 21, a first pressing component 22 and a second pressing component 23; the first guide member 21 is fixedly arranged on the shell 10, the first pressing component 22 is arranged on the first guide member 21, and the second pressing component 23 is slidably passed through the first pressing component 22. The setting of the first guide member 21 can guide the first pressing component 22, and then can guide the second pressing component 23 slidably arranged on the first pressing component 22, thereby limiting the direction of the first pressing component 22 and the second pressing component 23 when performing linear reciprocating motion.

[0060] Further, the first pressing assembly 22 includes a second guide 221 and a fixing assembly 222, the second guide 221 is slidably disposed in the first guide 21, and the fixing assembly 222 is disposed between the second guide 221 and the first guide 21, and the second guide 221 can be fixed to the first guide 21 so that the two do not move relative to each other. Optionally, the fixing assembly 222 includes two connecting pieces 2221 and two knobs 2222, the two connecting pieces 2221 are respectively disposed at the two ends of the first guide 21, the knob 2222 passes through the connecting piece 2221 and abuts against the second guide 221, and the sliding connection between the first guide 21 and the second guide 221 can be achieved by loosening the knob 2222. By tightening the knob 2222, the fixed connection between the first guide 21 and the second guide 221 can be achieved, and then the position of the first guide 21 and the second guide 221 can be adjusted. Preferably, a limiting protrusion 2211 is provided at one end of the second guide member 221 facing outside the housing 10 , so as to limit the movement of the second guide member 221 .

[0061] Specifically, Figures 1 to 5 As shown, when the knife switch 40 is in the initial position (at this time, the knife switch 40 is in the power-off state), there is a certain gap between the end of the second guide member 221 facing the outside of the shell 10 and the first guide member 21. The connecting piece 2221 and the second guide member 221 are tightened and fixed by the knob 2222, so that the second guide member 221 and the first guide member 21 can be fixed so that the two will not move relative to each other; at this time, the operator can drive the driven component 31 to move by pressing the second pressing component 23, thereby pushing the switch component 32 to move upward in the vertical direction, and then the knife switch 40 can be pushed to turn on the corresponding power supply. When the knife switch 40 needs to be closed, the operator needs to first loosen the knob 2222 so that the second guide member 221 can slide relative to the first guide member 21, and then slide the second guide member 221 toward the driven component 31, and slide until the limit protrusion 2211 abuts against the first guide member 21 and stops. During this process, the driven component 31 is further driven, so that the switch component 32 continues to move upward to the top of the knife switch 40, and then by resetting the second pressing component 23 and the second guide member 221, the driven component 31 can drive the switch component 32 to move downward in the vertical direction, thereby pushing the knife switch 40 to move downward, and the knife switch 40 can be closed, so that the power is turned off.

[0062] Alternatively, if Figure 1As shown, the second pressing assembly 23 includes a first sliding member 231, a first push plate 232 and a second push plate 233. The first sliding member 231 is slidably arranged in the first pressing assembly 22. The first push plate 232 is arranged at one end of the first sliding member 231 away from the housing 10. One end of the second push plate 233 is arranged at the other end of the first sliding member 231, and the other end can drive the driven assembly 31. The operator pushes the first sliding member 231 to slide toward the driven assembly 31 by pressing the first push plate 232, so that the second push plate 233 drives the driven assembly 31 to move. Preferably, the diameters of the first push plate 232 and the second push plate 233 are both larger than the inner diameter of the second guide member 221, so as to achieve the position limiting of the first push plate 232 and the second push plate 233.

[0063] Furthermore, the second pressing assembly 23 also includes a first elastic member 234, and the first elastic member 234 is arranged between the first pressing assembly 22 and the first push plate 232, that is, between the second guide member 221 and the second push plate 233. After the first push plate 232 is pressed and pushes the second pushing movement, the first elastic member 234 is in a stretched state. When no force is applied to the first push plate 232, the first elastic member 234 can drive the first push plate 232, the second push plate 233 and the first sliding member 231 to reset, which is convenient and quick.

[0064] Optionally, the second pressing assembly 23 further includes a locking member (not shown in the figure), which is disposed between the first push plate 232 and the second guide member 221, so that when the operator presses the first push plate 232 to abut against the second guide member 221, the first push plate 232 and the second guide member 221 are locked, and when the first push plate 232 is turned with the knob 2222 or pressed again, the first push plate 232 and the second guide member 221 are released, so that the first push plate 232 is reset. It can be understood that in this embodiment, the locking member includes a buckle and a slot, and one of the first push plate 232 and the second guide member 221 is provided with a buckle, and the other is provided with a slot, so that the first push plate 232 and the second guide member 221 can be locked and released. In other embodiments, the locking member can be other structures that can realize the detachable connection between the first push plate 232 and the second guide member 221, which is not specifically limited here.

[0065] Specifically, Figures 1 to 3 As shown, when the knife switch 40 needs to be opened, the operator presses the first push plate 232 so that the first push plate 232 is locked with the second guide member 221. At this time, the first push plate 232 pushes the first sliding member 231 and the second push plate 233 to move toward the driven component 31, and drives the driven component 31 so that the driven component 31 drives the switch component 32 to move upward, and then the switch component 32 pushes the knife switch 40 to move, so that the knife switch 40 turns on the corresponding power supply.

[0066] In this embodiment, if Figure 1 As shown, the above-mentioned driven component 31 includes a telescopic member 311 and a second sliding member 312, one end of the telescopic member 311 abuts against the other side of the housing 10, and the other end can be driven by the pressing mechanism 20, so that when the pressing mechanism 20 is pressed or released, the telescopic member 311 can be squeezed or released in the horizontal direction, so that the telescopic member 311 makes a linear reciprocating motion in the vertical direction; the second sliding member 312 is arranged on the side of the telescopic member 311 facing the switch component 32, so that when the telescopic member 311 makes a linear reciprocating motion in the vertical direction, the second sliding member 312 follows the telescopic member 311 to make a linear reciprocating motion in the vertical direction, and then can push the switch mechanism 30 to make a linear reciprocating motion in the vertical direction. Optionally, the telescopic member 311 is an airbag, which has a simple structure, low cost, and can realize the telescopic function of the telescopic member 311.

[0067] Optionally, in this embodiment, the bottom end of the telescopic member 311 abuts against the bottom of the housing 10, and the top end of the telescopic member 311 is spaced apart from the top of the housing 10, so that the telescopic member 311 can be telescoped toward the top of the housing 10 after being compressed and released in the horizontal direction. It is understandable that in other embodiments, the telescopic member 311 can also abut against the top of the housing 10 and be spaced apart from the bottom of the housing 10, so that the telescopic member 311 can telescope downward in the vertical direction, which is not specifically limited here.

[0068] Further optionally, the driven component 31 also includes a second elastic member 313, which is sleeved on the second sliding member 312 and located between the switch component 32 and the housing 10, so that when the telescopic member 311 is extended and retracted, the second elastic member 313 is in a stretched state, and when the telescopic member 311 is reset, the second elastic member 313 can drive the switch component 32 to reset, and during the resetting process can drive the switch 40 to move downward to the position of turning off the power.

[0069] In this embodiment, if Figure 1 As shown, the switch assembly 32 includes a third guide 321 and a stopper 323; the third guide 321 is connected to the driven assembly 31 and can move with the movement of the driven assembly 31, and the stopper 323 is arranged on one side of the third guide 321. Through the above structure, when the switch assembly 32 opens or closes the knife switch 40, the stopper 323 can make a straight reciprocating motion along the vertical direction with the third guide 321, so that the stopper 323 pushes the knife switch 40 to move, thereby causing the knife switch 40 to open or close the corresponding power supply.

[0070] Furthermore, the switch assembly 32 further includes a third sliding member 322 and a stopper 324. The third sliding member 322 is slidably connected to the third guide member 321, and one end is connected to the stopper 323. The stopper 324 is disposed at the other end of the third sliding member 322 and is elastically connected to the third guide member 321, so that after the switch 40 is fully powered on, when the switch 40 needs to be turned off, the stopper 323 needs to continue to move upward to the top of the switch 40, and when the stopper 323 abuts against the switch 40, the stopper 323 is moved upward to the top of the switch 40. 0, the force applied by the knife 40 to the stopper 323 enables the stopper 323 to move along with the third sliding member 322 toward the limit block 324, so that the stopper 323 can pass over the knife 40 to the top of the knife 40. When the stopper 323 is above the knife 40, the stopper 323 is reset due to the elastic connection between the limit block 324 and the third guide member 321, so that the knife 40 can be pushed during the downward movement of the stopper 323 to close the knife 40. Optionally, a third elastic member 325 is provided between the limit block 324 and the third guide member 321 to realize the elastic connection between the limit block 324 and the third guide member 321.

[0071] This embodiment also provides a power distribution cabinet, such as Figure 2 As shown, the power distribution cabinet includes a cabinet body 200, a cabinet door 300, a rotating plate 400 and the above-mentioned power distribution switch. The cabinet door 300 is rotatably connected to the cabinet body 200, and the rotating plate 400 is rotatably connected to the top of the inner wall of the cabinet body 200. The power distribution switch is arranged on the rotating plate 400, which can improve the safety of the operator when operating the power supply in the power distribution cabinet, and when the operator needs to inspect or repair the internal structure of the power distribution cabinet, the rotating plate 400 can be opened to expose the internal structure of the power distribution cabinet, which is convenient for the operator to inspect or repair. Optionally, in this embodiment, the fixed plate 12 can be omitted, so that the U-shaped frame 11 is directly fixed to the rotating plate 400 to form a shell, which reduces some parts and reduces the weight.

[0072] Furthermore, a fourth elastic member 500 is provided between the rotating plate 400 and the top of the inner wall of the cabinet 200, so that the rotating plate 400 can be reset after the operator opens the rotating plate 400 for inspection or maintenance. Optionally, the power distribution cabinet further includes a limit seat 600, which is arranged at the bottom of the inner wall of the cabinet 200 and at the side of the rotating plate 400 facing the inside of the cabinet 200, so as to limit the rotating plate 400 and prevent the rotating plate 400 from rotating too much inward and causing damage to the components inside the cabinet 200.

[0073] In this embodiment, the working principle of the power distribution switch is:

[0074] Reference Figure 2When the power distribution cabinet is not powered on, the pressing mechanism 20, the switch mechanism 30 and the switch 40 in the power distribution switch are all in the initial position. Figure 3 When the knife switch 40 needs to be opened, the operator presses the first push plate 232 so that the first push plate 232 is locked with the second guide member 221. During this process, the first push plate 232 pushes the first sliding member 231 and the second push plate 233 to move toward the telescopic member 311 and squeezes the telescopic member 311, so that the telescopic member 311 extends upward in the vertical direction, driving the second sliding member 312 to move upward, and then pushing the third guide member 321 to move upward, so that the block 323 pushes the knife switch 40 to move and turn on the corresponding power supply.

[0075] Reference Figure 4 and Figure 5 When the knife 40 needs to be closed, the operator first loosens the knob 2222 to allow the second guide member 221 to slide relative to the first guide member 21, and then slides the second guide member 221 toward the telescopic member 311 until the limiting protrusion 2211 abuts against the first guide member 21 and stops. During this process, the telescopic member 311 is further squeezed, causing the stopper 323 to continue to move upward. At this time, the knife 40 cannot continue to move upward, so the stopper 323 moves along the first guide member 21 under the action of the force given by the knife 40. The sliding direction of the three guide members 321 moves in the direction away from the knife switch 40. At this time, the third elastic member 325 is in a stretched state until the block 323 bypasses the knife switch 40 and reaches the top of the knife switch 40. Under the action of the third elastic member 325, the block 323 is reset; and then by resetting the second pressing assembly 23 and the second guide member 221, the telescopic member 311 can drive the block 323 to move downward in the vertical direction, thereby pushing the knife switch 40 to move downward, and the knife switch 40 can be closed, so that the power is turned off.

[0076] Embodiment 2:

[0077] The present embodiment provides a power distribution switch and a power distribution cabinet. The difference between the present embodiment and the first embodiment is that, in the present embodiment, the block 323 includes a block body and an active buckle. The block body is fixedly connected to the third sliding member 322. The active buckle is elastically arranged on the side of the block body facing the knife 40, which can increase the connection area between the block 323 and the knife 40, so that the block 323 can better push the knife 40 to open or close the corresponding power supply. Specifically, when the block 323 abuts against the knife 40 and pushes the knife 40 to move, the active buckle is clamped on the knife 40, so that the block 323 can be better contacted and fixed with the knife 40, and when the block 323 needs to pass over the knife 40, the knife 40 applies a force to the block 323, so that the active buckle is pressed into the block body by the knife 40 and the block body moves away from the knife 40, until the block 323 passes over the knife 40 and resets again, and then the knife 40 is closed.
