Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power distribution cabinet, in particular to a power failure uninterrupted automatic switching power distribution cabinet. BACKGROUND

[0002] The external line of the power distribution cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs, such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. With the continuous development of industry, the power distribution cabinet is updated faster and faster, and the power failure automatic switching power distribution cabinet is also continuously popularized. However, the current power failure automatic switching power distribution cabinet mainly adopts double or multi-path power supply in the primary system, and is assisted by the backup automatic switching device in the secondary system. In the continuous power supply requirements of petrochemical, metallurgical and other industries, the use effect of the backup automatic switching device is not ideal.

[0003] The background technology of a arc extinction power distribution cabinet with publication number CN117239613B proposes the problem that: the existing pressure relief measures are mostly through the opening of holes and grooves on the cabinet body to release the high-temperature and high-pressure gas generated instantaneously. However, the simple hole and groove protection effect is general, and the high-temperature and high-pressure gas quickly discharged outward through the air slot may still cause harm to the facilities or personnel around the power distribution cabinet.

[0004] In summary, the existing technology has the following problems:

[0005] The existing backup automatic switching power distribution cabinet is not convenient for the rapid discharge of high-temperature and high-pressure gas generated instantaneously due to short circuit, etc. After the first discharge, high-temperature and high-pressure gas is continuously generated in the backup automatic switching power distribution cabinet, and the residual high-temperature and high-pressure gas in the backup automatic switching power distribution cabinet is continuously accumulated, which seriously affects the safety of the use of the backup automatic switching power distribution cabinet. Referring to the above application file, although the high-temperature and high-pressure gas generated instantaneously can be released, the structure is relatively complex, the weight of the structure itself limits the release speed of the high-temperature and high-pressure gas, and after the first release, the high-temperature and high-pressure gas cannot be fully discharged due to the weight. The top plate after ejection is located at the top of the high-temperature and high-pressure gas flow channel, which further affects the release speed. Moreover, the high-temperature and high-pressure gas can only be released instantaneously, and the residual high-temperature and high-pressure gas in the power distribution cabinet cannot be discharged, which has certain disadvantages. In order to solve the above problems, a power failure uninterrupted automatic switching power distribution cabinet is proposed. SUMMARY

[0071] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the protection scope of the present application.

[0072] Embodiment one: please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 15 , a power-off uninterrupted automatic switching type power distribution cabinet, comprising a power distribution cabinet 1, further comprising a mounting mechanism 2 arranged at the top of the power distribution cabinet 1 and a pressure relief mechanism 3 arranged at the top of the power distribution cabinet 1 through the mounting mechanism 2;

[0073] Please refer to Figure 4 and Figure 5 , the mounting mechanism 2 comprises:

[0074] a bottom frame 21 arranged at the top of the power distribution cabinet 1, an outer wall of the bottom frame 21 is sleeved with a top frame 22, both sides of an outer wall of the top frame 22 are provided with a clamping assembly 23 for clamping with the bottom frame 21, and an outer wall of the bottom frame 21 is provided with an abutting assembly 24 for limiting the clamping assembly 23;

[0075] Please refer to Figure 7 , Figure 8 and Figure 9 , the pressure relief mechanism 3 comprises:

[0076] The first frame 32 is fixedly arranged on the inner wall of the top frame 22 and extends to the inner side of the bottom frame 21. The inner wall of the first frame 32 is fixedly provided with a second frame 33. The inner side of the second frame 33 is provided with a plurality of flip assemblies 31 arranged at intervals.

[0077] Please refer to Figure 10 and Figure 11 The flip assembly 31 comprises:

[0078] The fixed rod 314 is arranged on the inner wall of the second frame 33. The side wall of the fixed rod 314 is slidingly provided with a sleeve 317, so that the sleeve 317 rotates around the central axis of the fixed rod 314. The outer wall of the sleeve 317 is fixedly provided with a baffle 311. When pressure gas appears in the power distribution cabinet 1, the baffle 311 is driven to flip by the pressure of the gas, thereby passively relieving the pressure in the power distribution cabinet 1. The outer side of the power distribution cabinet 1 is provided with a pressure relief assembly 34 for actively relieving the pressure in the power distribution cabinet 1.

[0079] The flip assembly 31 further comprises:

[0080] The connecting cover 312 is fixedly arranged at both ends of the sleeve 317. The end of the connecting cover 312 away from the sleeve 317 and both ends of the fixed rod 314 extend into the first frame 32. The inner side of the end of the connecting cover 312 located in the first frame 32 is provided with a spring 315. The two ends of the spring 315 are fixedly connected with the inner wall of the connecting cover 312 and the side wall of the fixed rod 314, respectively, so that the baffle 311 has a downward flipping tendency.

[0081] The fixed part 313 is fixedly arranged at both ends of the fixed rod 314. The outer side of the fixed part 313 is fixedly connected with the first frame 32, so as to fix the fixed rod 314.

[0082] The flip assembly 31 further comprises:

[0083] The fixed frame 318 is fixedly arranged on the inner wall of the second frame 33 and is sleeved on the outer wall of the sleeve 317, so that the sleeve 317 rotates on the inner side of the fixed frame 318, thereby limiting the upward flipping position of the baffle 311 through the top of the fixed frame 318;

[0084] The limiting plate 319 is fixedly arranged on the top of the fixed frame 318 and extends to the bottom of the baffle 311, so as to support the baffle 311 from the bottom of the baffle 311. The limiting plate 319 is symmetrically arranged with the center point of the fixed frame 318.

[0085] The annular sliding block 316 is fixedly sleeved on both ends of the side wall of the fixed rod 314. Both ends of the inner wall of the sleeve 317 are provided with annular sliding grooves. The annular sliding block 316 is placed in the annular sliding groove, so that the sleeve 317 rotates, thereby limiting the flipping of the sleeve 317 and the baffle 311. The inner side of the baffle 311 is provided with an adsorption assembly 310.

[0086] In specific implementation, when high-temperature and high-pressure gas appears in the power distribution cabinet 1, the gas is blown into the second frame body 33 through the exhaust hole at the top of the power distribution cabinet 1, thereby driving the baffle 311 to rotate against the elastic force of the clockwork 315, so that the baffle 311 is flipped upward, thereby facilitating the rapid discharge of the high-temperature and high-pressure gas, thereby reducing the damage to the power distribution cabinet 1. By arranging the rotatable baffle 311, the high-temperature and high-pressure gas directly contacts the baffle 311 and drives the baffle 311 to rotate, thereby releasing the high-temperature and high-pressure gas. The stability of the release of the high-temperature and high-pressure gas is improved. Moreover, the baffle 311 does not block the channel for discharging the high-temperature and high-pressure gas after being flipped, thereby improving the pressure relief efficiency.

[0087] By arranging the clockwork 315, the baffle 311 always has a downward rotating trend and cooperates with the bottom plate 3103, so as to block the top of the power distribution cabinet 1 when the high-temperature and high-pressure gas is not released, thereby facilitating actual use. The baffle 311 is supported from the bottom of both sides of the baffle 311 by the limiting plate 319 and the bottom plate 3103, thereby improving the stability of the baffle 311. Moreover, the baffle 311 is limited from the top by the fixing frame 318, thereby avoiding the condition that the baffle 311 is excessively flipped due to excessive pressure of the instantaneous high-temperature and high-pressure gas, thereby improving the stability of the use of the baffle 311.

[0088] The rotation of the sleeve 317 is limited by the annular sliding block 316 and the annular sliding groove, thereby improving the stability of the rotation of the sleeve 317 and facilitating the magnetic attraction limiting of the adsorption assembly 310, thereby improving the stability of the baffle 311 in blocking the top of the power distribution cabinet 1.

[0089] The inner wall of the first frame body 32 is provided with a groove for sleeving the connecting cover 312, thereby facilitating the rotating use of the connecting cover 312 and fixing the fixing member 313 with the inner wall of the groove, thereby facilitating the fixation of the fixed rod 314.

[0090] Please refer to Figure 12 The adsorption assembly 310 comprises:

[0091] The bottom plate 3103 is fixed to the side of the fixing frame 318 away from the sleeve 317 and the inner wall of the second frame body 33. The top of the bottom plate 3103 is fixed with the magnet strip 3102.

[0092] The magnetic metal strip 3101 is fixed to the bottom of the baffle 311 and located at the side of the baffle 311 away from the sleeve 317. The top of the bottom plate 3103 and the bottom of the baffle 311 are both provided with mounting grooves for mounting the magnet strip 3102 and the magnetic metal strip 3101, so that the bottom of the baffle 311 is attached to the top of the bottom plate 3103 after the magnetic attraction of the magnetic metal strip 3101 and the magnet strip 3102.

[0093] In specific implementation, when the top of the bottom plate 3103 is in contact with the bottom of the baffle 311, the magnetic strip 3102 is attached to the magnetic metal strip 3101 under the limiting of the annular sliding block 316 and the annular sliding groove, thereby limiting the baffle 311, and further strengthening the stability of the baffle 311 shielding the top of the power distribution cabinet 1.

[0094] Due to the interval arrangement of the turnover assembly 31, the bottom plate 3103 is arranged away from the sleeve 317 and the inner wall of the second frame body 33 of the fixed frame 318, thereby corresponding to the position of the baffle 311, facilitating the magnetic attraction limiting and supporting of the baffle 311.

[0104] In specific implementation, after the instantaneous high-temperature and high-pressure gas in the power distribution cabinet 1 is released, there is still a lot of high-temperature and high-pressure gas remaining in the power distribution cabinet 1, in order to reduce the damage caused by the high-temperature and high-pressure gas to the power distribution cabinet 1 and the internal structure, the air suction fan 341 is started to exhaust the gas in the power distribution cabinet 1 through the air outlet pipe 343, so as to facilitate the release of the high-temperature and high-pressure gas remaining in the power distribution cabinet 1, and because the structure in the power distribution cabinet 1 is relatively complex, the flow of the gas is affected, and the high-temperature and high-pressure gas is prone to flowing upward due to its nature, so that the air suction fan 341 cannot quickly exhaust the high-temperature and high-pressure gas remaining in the power distribution cabinet 1, at this time, part of the gas exhausted by the air suction fan 341 is exhausted into the air inlet pipe 3464 through the shunt pipe 345, and then exhausted into the cylinder body 3466 through the air inlet pipe 3464, so as to drive the piston block 3463 and the rod body 3469 to move upward, so as to drive the baffle 311 to overturn through the top plate 3468, so as to facilitate the upward flow and exhaust of the high-temperature and high-pressure gas, reduce the damage caused by the high-temperature and high-pressure gas remaining in the power distribution cabinet 1 to the power distribution cabinet 1 and the internal structure, and reduce the situation that the power distribution cabinet 1 is combusted or even exploded due to the accumulation of a large amount of high-temperature and high-pressure gas in the power distribution cabinet 1 due to insufficient pressure;

[0105] The gas in the cylinder body 3466 is exhausted through the gas guiding hole 3462, and the gas exhausted through the gas guiding hole 3462 is exhausted to the outside through the gas guiding groove 3460, so as to avoid the accumulation of a large amount of gas in the cylinder body 3466, and the inner wall diameter of the gas guiding hole 3462 is smaller than the inner wall diameter of the air inlet pipe 3464, so as to ensure that the gas in the cylinder body 3466 has the pressure of the piston block 3463 and the like, so as to avoid affecting the movement of the rod body 3469;

[0106] The rod body 3469 increases the contact area with the baffle 311 through the top plate 3468, facilitates the baffle 311 to flip to a larger extent, and limits the rod body 3469, avoids the rod body 3469 from entering the cylinder body 3466, and improves the stability of use;

[0107] The first valve 344 and the second valve 342 cooperate to adjust the flow of the gas in the exhaust pipe 343 and the shunt pipe 345, so as to adjust the exhaust capacity of the exhaust pipe 343 and the flipping degree of the baffle 311 according to actual conditions, and facilitate actual pressure relief use.

[0108] Embodiment two: please refer to Figure 4 、 Figure 5 and Figure 6 The difference between the technical scheme of the embodiment and the embodiment one is that the clamping assembly 23 comprises:

[0109] The clamping claw 231 is fixedly arranged on the outer wall of the top frame 22, and the bottom inner side of the clamping claw 231 is provided with a first plane 232;

[0110] The clamping groove 234 is arranged on the outer wall of the bottom frame 21, and is matched with the clamping claw 231, and the top inner wall of the clamping groove 234 is provided with a second plane 236, and the first plane 232 and the second plane 236 abut after the clamping claw 231 is embedded in the clamping groove 234;

[0111] The first arc surface 235 is arranged on the bottom of the clamping claw 231, and the second arc surface 233 is arranged on the top outer side of the bottom frame 21, and the first arc surface 235 and the second arc surface 233 are in contact, so that the clamping claw 231 moves smoothly along the outer wall of the bottom frame 21.

[0112] In the specific implementation, the bottom frame 21 is fixed on the top of the power distribution cabinet 1 by bolts and the like, and the inner wall of the bottom frame 21 is located outside the exhaust hole on the top of the power distribution cabinet 1, so as to avoid affecting the flow of high-temperature and high-pressure gas in the power distribution cabinet 1, and then the top frame 22 and the like are sleeved outside the bottom frame 21 from the top of the bottom frame 21, in this process, the first arc surface 235 and the second arc surface 233 are in contact and continuously extrude the clamping claw 231, and since the clamping claw 231 is made of elastic metal material, the clamping claw 231 enters the clamping groove 234 along the outer side of the bottom frame 21, so as to clamp and fix the bottom frame 21 and the top frame 22, without using traditional bolts for fixing, which is convenient for disassembly;

[0113] The first arc surface 235 and the second arc surface 233 facilitate the downward movement of the clamping claw 231 along the outer side of the bottom frame 21, so that the clamping claw 231 is embedded in the clamping groove 234. After the clamping claw 231 is embedded in the clamping groove 234 by the first plane 232 and the second plane 236, the second plane 236 resists the first plane 232, thereby avoiding the influence of the stability of the pressure relief mechanism 3 and the like when high-temperature and high-pressure gas is generated in the power distribution cabinet 1.

[0114] The abutting assembly 24 comprises:

[0115] The abutting claw 241 is fixedly arranged on the outer wall of the bottom frame 21 and is symmetrically arranged with the center point of the bottom frame 21. The abutting claw 241 and the clamping claw 231 are both made of elastic metal material. The inner side of the abutting claw 241 is provided with an abutting inclined surface 243. The abutting inclined surface 243 cooperates with the first arc surface 235 to facilitate the smooth entry of the clamping claw 231 into the inner side of the abutting claw 241 when the clamping claw 231 moves downward.

[0116] The abutting groove 242 is arranged on the outer side wall of the clamping claw 231 and is adapted to the abutting claw 241.

[0117] In specific implementation, after the clamping claw 231 enters the clamping groove 234, the abutting claw 241 is embedded in the abutting groove 242, thereby abutting the clamping claw 231 from the outside of the clamping claw 231 to prevent the clamping claw 231 from being separated from the clamping groove 234, thereby improving the stability of the connection. When it is necessary to disassemble the pressure relief mechanism 3 and the like, the abutting claw 241 is turned outward to separate the abutting claw 241 from the abutting groove 242. Then, the clamping claw 231 is turned outward to separate the clamping claw 231 from the clamping groove 234. Thus, the top frame 22 and the bottom frame 21 can be separated, thereby facilitating the disassembly of the pressure relief mechanism 3 and the like. The traditional bolt is not needed for disassembly, the stability of disassembly is improved, the pressure relief mechanism 3 can be used multiple times, and recycling is facilitated.

[0118] The first arc surface 235 cooperates with the abutting inclined surface 243 to facilitate the downward movement of the clamping claw 231 along the inner side of the abutting claw 241, and the abutting inclined surface 243 abuts the clamping claw 231 to facilitate the movement of the clamping claw 231 along the outer wall of the bottom frame 21 and the entry of the clamping claw 231 into the clamping groove 234.

[0119] The abutting claw 241 and the clamping claw 231 are both made of elastic metal material, which is designed to deform and recover after the abutting claw 241 and the clamping claw 231 are deformed, so as to embed the clamping groove 234 and the abutting groove 242, facilitate actual limiting use, and not include the stretching and contracting properties of the elastic metal material. The specific design is determined according to actual conditions, and will not be described here.

[0120] The air suction fan 341 of the application is connected with an external power supply and a controller through wires for actual control and use, which are all prior art and will not be described here.

[0121] When the application is implemented:

[0122] S1: When pressure gas is generated in the power distribution cabinet 1, the pressure gas drives the baffle 311 to flip, thereby discharging the pressure gas in the power distribution cabinet 1;

[0123] S2: After part of the pressure gas is discharged, the gas pressure in the power distribution cabinet 1 is reduced, that is, the power distribution cabinet 1 is continuously pressure-released by the pressure relief assembly 34, thereby reducing the amount of high-temperature and high-pressure gas accumulated in the power distribution cabinet 1 due to residual or subsequent continuous discharge, so as to reduce the damage to the switching devices and the like in the power distribution cabinet 1;

[0124] S3: When the power distribution cabinet 1 cannot be used due to pressure gas or failure, the pressure relief mechanism 3 is separated from the power distribution cabinet 1 through the mounting mechanism 2, and the pressure relief mechanism 3 is mounted to a new power distribution cabinet 1 through mounting, so as to facilitate the disassembly of the pressure relief mechanism 3. When the power distribution cabinet 1 is damaged, the traditional bolt fixing method may be stuck, so as to reduce the inconvenience caused by the traditional bolt fixing method.

[0125] As shown in Figure 1 and Figure 16 , an artificial zero-crossing fast module 4 is arranged in the power distribution cabinet 1 and is connected in parallel at both ends of the fast circuit breaker, which is used for quickly completing the zero-crossing opening of the main power supply circuit breaker and the fast closing of the standby power supply circuit breaker when the external network fails. This is prior art and will not be described here.

[0126] Meanwhile, the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.

[0127] It should be noted that, in this document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0128] Although embodiments of the application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the application, the scope of which is defined by the appended claims and their equivalents.
