Description

Technical Field

[0002] Switchgear is an electrical device mainly used to control, protect and monitor circuits in power systems. It is usually composed of cabinets, circuit breakers, disconnectors, load switches, contactors, fuses and other electrical components. The switchgear has the following functions: first, it controls the on and off of the circuit to facilitate the operation of the power system; second, it protects the circuit. When overcurrent, short circuit and other faults occur, the circuit is cut off in time to protect the safety of equipment and personnel; third, it monitors the operating status of the circuit and provides various electrical parameters for easy maintenance and management. Switchgear is widely used in power plants, substations, industrial and mining enterprises and other places.

[0044] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0045] The present invention provides a high-voltage switch cabinet capable of wireless temperature measurement and temperature control. Figures 1 to 10 Elaborate in detail.

[0046] A high-voltage switch cabinet capable of wireless temperature measurement and temperature control, comprising a cabinet body 1, a first mounting mechanism 4 and a second mounting mechanism 5 are arranged in parallel in the cabinet body 1, an air duct is arranged in the hollow inside of the first mounting mechanism 4 and the second mounting mechanism 5, a plurality of instrument mounting positions 53 are arranged on the first mounting mechanism 4 and the second mounting mechanism 5, each instrument mounting position 53 is provided with an air collecting hood 54 connected to the air duct, and a first temperature sensor 6 is arranged on the air collecting hood 54 facing one end of the air duct;

[0047] A heat dissipation mechanism 2 is provided between the first mounting mechanism 4 and the second mounting mechanism 5. The heat dissipation mechanism 2 is provided on the side wall of the cabinet 1 corresponding to the end of the mounting mechanism, and the heat dissipation mechanism 2 is connected to the first mounting mechanism 4 and the second mounting mechanism 5.

[0048] The first temperature sensor 6 and the heat dissipation mechanism 2 are both wirelessly connected to an industrial computer.

[0049] The present invention can realize individual monitoring of the temperature of each instrument by arranging an air collecting hood 54 and a corresponding first temperature sensor 6 on each instrument installation position 53. The temperature of each instrument is transmitted to the industrial computer through the first sensor, and the heat dissipation mechanism 2 is controlled by the industrial computer, so that the airflow quickly enters the air duct along the air collecting hood, takes away the heat generated by the instrument, and the heat is dissipated by the heat dissipation mechanism 2, thereby realizing rapid temperature measurement and control in the high-voltage switch cabinet.

[0050] Specifically, an industrial computer is installed on the wall of the switch room to receive and process the temperature data sent back by the first temperature sensor 6. The first temperature sensor 6 detects the temperature data and uploads the collected data to the industrial computer through a bus or other means. The received temperature data is analyzed by the software in the industrial computer, and an alarm is immediately sounded when the alarm temperature is exceeded. This not only enables real-time online management of electrical equipment, detects potential faults at any time, and keeps a clear understanding of the operating status of electrical equipment, so that large-scale power outages caused by excessive temperature rise and explosion of electrical equipment will not occur, but also enables centralized online monitoring of all equipment in the plant. The on-duty personnel can timely and comprehensively grasp the overall operating status of the equipment without going out, which can reduce the workload of personnel inspections, reduce the number of personnel in disguise, and reduce labor costs for the enterprise; it can also extend the operating time of the equipment and create more economic benefits for the company.

[0051] In some embodiments, the wind collecting hood 54 is set at the position corresponding to the wiring of the instrument. Since the wiring terminals of the instrument are more prone to heat generation, aligning the wind collecting hood 54 with the wiring position of the instrument can quickly remove the heat from the wiring terminals through airflow, thereby avoiding heat accumulation and eventually causing a fire.

[0052] In some embodiments, the first mounting mechanism 4 and the second mounting mechanism 5 have the same structure;

[0053] The second mounting mechanism 5 includes a connecting plate and a mounting plate 52 which are connected in an L-shape and contain an air duct inside. The mounting plate 52 is fixedly arranged on the inner wall of the box, and a plurality of instrument mounting positions 53 are evenly spaced on the mounting plate 52. The mounting seat is arranged on the side wall of the cabinet 1 which is the same as the heat dissipation mechanism 2. An air guide port 521 is arranged at one end of the mounting plate 52 away from the connecting plate.

[0054] Furthermore, the mounting plate 52 of the first mounting mechanism 4 facing the heat dissipation mechanism 2 and the mounting plate 52 of the second mounting mechanism 5 facing the heat dissipation mechanism 2 are both provided with air duct openings.

[0055] Air ducts are provided in both the connecting plate and the mounting plate 52, and the two sections of the air ducts are connected to ensure that the airflow can flow in from the air collecting hood and be discharged from the opening of the air duct, thereby ensuring the smooth flow of the airflow. At the same time, the setting of the air guide port 521 can play a role in assisting the air intake;

[0056] In one embodiment, the air guide port 521 is disposed inside the cabinet 1 to draw the air with a lower temperature away from the instrument in the cabinet 1 into the mounting plate 52, thereby accelerating the heat dissipation at the position of the air collecting hood corresponding to the instrument;

[0057] In another embodiment, the air guide port 521 penetrates the side wall of the cabinet 1 and is connected to the external environment, so that air from the external environment can enter the mounting plate 52. Since the instruments in the cabinet 1 will generate a large amount of heat, the air from the external environment will be lower than the air inside the cabinet 1. Therefore, the air outside the cabinet 1 enters the air duct of the mounting plate 52, which can accelerate heat exchange and remove heat from the air collecting hood more quickly.

[0058] In some embodiments, a plurality of sets of enclosed components 55 are disposed in the mounting plate 52, and each set of enclosed components 55 is disposed between two adjacent air collecting covers 54;

[0059] The closing component 55 includes a mounting frame 551 arranged parallel to the cross section of the air duct, an air guide channel 5511 for air flow to pass through is opened in the middle of the mounting frame 551, a closing plate 552 which can block the air guide channel 5511 is rotatably connected to the mounting frame 551, and a torsion spring 553 for controlling the closing plate 552 to reset is arranged between the closing plate 552 and the mounting frame 551.

[0060] The setting of the closing component 55 can play a role in closing the air duct. When the power of the heat dissipation mechanism 2 remains unchanged or increases, the closing plate 552 of any closing component 55 is closed, so that the air duct in the direction of the closing plate 552 away from the heat dissipation mechanism 2 is closed. At this time, since a part of the air flow source is cut off, the air flow can only be obtained from the air hood corresponding to the air duct that is not blocked by the closing plate 552, that is, the air flow of the air hood at this position is increased, so that the instrument corresponding to the air hood can be cooled more quickly. The setting of the torsion spring 553 can keep the closing plate 552 in a normally open state, so that the air duct remains in a normally unobstructed state, avoiding the situation where the closing plate 552 is closed under normal conditions and blocks the air duct.

[0061] In one embodiment, when the closing plate 552 is in a closed state, a gap of 1-1.5 mm is provided between the closing plate 552 away from the rotating connection end and the mounting frame 551, so that a small amount of air can pass through the gap, thereby ensuring that the air collecting hood 54 on the side of the closing plate 552 away from the heat dissipation mechanism 2 still has normal air circulation.

[0062] In one embodiment, the closing plate 552 maintains a certain angle with the remaining mounting frame 551 when in the normally open state, ensuring that when the power of the heat dissipation mechanism 2 is increased, the air flow rate in the air duct increases, resulting in increased wind force to stably close the closing plate 552.

[0063] In some embodiments, along the direction from the air guide port 521 to the air duct opening, the elastic force of the torsion spring 553 of each group of closing components 55 is sequentially increased, so that different closing components 55 can be closed in sequence as the power of the heat dissipation mechanism 2 is increased, and the opening and closing state of the closing components 55 can be controlled by controlling the wind force in the air duct.

[0064] In some embodiments, the heat dissipation mechanism 2 includes a connection shell 21 fixedly connected to the cabinet 1, and a fan 22 is fixedly arranged on the connection shell 21 toward the outside of the cabinet 1;

[0065] The connecting shell 21 is provided with a first air guide groove 211 communicating with the air duct opening of the first mounting mechanism 4 and a second air guide groove 212 communicating with the air duct opening of the second mounting mechanism 5 .

[0066] The setting of the fan 22 can extract the air in the cabinet 1. At the same time, the setting of the first air guide groove 211 and the second air guide groove 212 can connect the air duct of the first mounting mechanism 4 and the air duct of the second mounting mechanism 5, thereby accelerating the air flow rate in the air duct and accelerating the airflow to take away the heat generated by the corresponding instrument of the air collecting hood from the air duct.

[0067] In some embodiments, a center plate is provided on the connecting shell 21 facing away from the fan 22, ventilation holes 213 are provided on both sides of the center plate, and a regulating mechanism 3 for controlling the opening and closing of the first air guide groove 211 and the second air guide groove 212 is provided on the center plate, and the regulating mechanism 3 includes a driving motor 31, an air hole baffle, an air guide groove baffle, and a connecting member 32;

[0068] The connecting piece 32 is rotatably connected to the center plate;

[0069] The drive motor 31 is fixedly mounted on the connecting piece 32, and the output end of the drive motor 31 passes through the connecting piece 32 toward the center plate and is rotatably connected to the center plate, and the drive motor 31 is wirelessly connected to the industrial computer;

[0070] Two groups of wind hole baffles are provided, and the two groups of wind hole baffles are symmetrically arranged on both sides of the connecting piece 32, and the two groups of wind hole baffles are fixedly connected to the connecting piece 32, and a wind-passing gap is provided between the two groups of wind hole baffles, and the shielding area of ​​the two groups of wind hole baffles is not less than the ventilation cross-sectional area of ​​the ventilation hole 213;

[0071] The air guide slot baffle is arranged between the two groups of wind hole baffles, and the center axis of the wind gap and the center line of the air guide slot baffle are arranged in the same plane.

[0072] When the first temperature sensor 6 in the first mounting mechanism 4 (or the second mounting mechanism 5) detects that the instrument generates heat, the industrial computer controls the driving motor 31 to rotate, so that the air guide groove blocking piece blocks the second air guide groove 212 (or the first air guide groove 211) corresponding to the second mounting mechanism 5 (or the first mounting mechanism 4). At this time, the air flow source drawn by the fan 22 mainly comes from the first mounting mechanism 4 (or the second mounting mechanism 5), thereby accelerating the air flow rate in the first mounting mechanism 4 (or the second mounting mechanism 5), and realizing accurate cooling of the mounting mechanism with abnormal temperature. Combined with the closed component 55, further accurate temperature control can be realized for the instrument with abnormal temperature.

[0073] The setting of the ventilation hole 213 can facilitate the extraction of gas in the cabinet. The relative positions of the wind hole baffle and the air guide groove baffle are set so that the wind hole baffle can completely block the ventilation hole 213 when the air guide groove baffle is working, so that the airflow extracted by the fan 22 comes completely from the installation mechanism where the temperature abnormality occurs, thereby further accelerating the cooling operation of the instrument with abnormal temperature.

[0074] In some embodiments, the fan 22 is provided with multiple speed levels, and the number of speed levels of the fan 22 = the number of the sealing components 55 + 1;

[0075] When the fan 22 is operating at the initial gear speed, the elastic force of all torsion springs 553 is greater than the wind force on the closing plate 552 at this time, the air guide channels 5511 of all closing components 55 are opened, all air collecting hoods are connected to the air duct openings, and the air flow in the air duct can flow smoothly from the air guide port 521 to the air duct opening, and the air flow of each air collecting hood is the same;

[0076] When the fan 22 is operating at the highest speed, the elastic force of all torsion springs 553 is smaller than the wind force on the closing plate 552 at this time, and the air guide channels 5511 of all closing components 55 are blocked by the closing plate 552, and only the air collecting hood closest to the connecting plate is connected to the air duct opening. At this time, the air flow in the air collecting hood closest to the connecting plate is much greater than the air flow in other air collecting hoods;

[0077] The closing states of the closing plates 552 of the multiple groups of closing components 55 along the direction from the air guide port 521 to the air duct opening are all controlled one by one in sequence by the gear positions above the initial gear position of the fan 22.

[0078] In one embodiment, the multiple gear settings of the fan 22 correspond to multiple groups of closed components 55. In one embodiment, the fan 22 is provided with three gears, and the air collecting hood 54 is provided with three, which are respectively the first air collecting hood 541, the second air collecting hood 542 and the third air collecting hood 543 along the air guide port 521 toward the air duct opening. In this case, there are two closed components 55, which are respectively located between the first air collecting hood 541 and the second air collecting hood 542 and between the second air collecting hood 542 and the third air collecting hood 543;

[0079] When the fan 22 is in the initial gear 1, the air flow in all the air collecting hoods is the same, the two closing components 55 are in the open state, and the air flow can flow in from the air guide port 521 and each air collecting hood, and the air flow rate in each air collecting hood is recorded as the normal flow rate;

[0080] When the fan 22 is in the second gear, the air flow velocity in the air duct increases, and the wind force increases. At this time, the sealing component 55 between the first air collecting cover 541 and the second air collecting cover 542 is closed under the action of air pressure, and the air flow velocity in the first air collecting cover 541 remains at a normal flow velocity, and the air flow velocity in the second air collecting cover 542 and the third air collecting cover 543 increases, thereby accelerating the heat loss at the corresponding positions of the second air collecting cover 542 and the third air collecting cover 543;

[0081] When the fan 22 is in the third gear, the wind force in the air duct increases again. At this time, the two sets of sealing components 55 are closed under the action of air pressure, and the airflows in the second air collecting hood 542 and the first air collecting hood 541 maintain normal flow rates. The airflow speed in the third air collecting hood 543 increases again, thereby accelerating the heat loss at the corresponding position of the third air collecting hood again.

[0082] In some embodiments, a filter plate 23 is provided at one end of the fan 22 facing the outside of the cabinet 1. The filter plate 23 can prevent foreign matter in the external environment from entering the fan 22, thereby reducing the probability of the fan 22 being damaged by foreign matter.

[0083] In some embodiments, at least one group consisting of a heat dissipation mechanism 2, a first mounting mechanism 4, and a second mounting mechanism 5 is provided in the cabinet 1. The provision of multiple groups can increase the instrument capacity in the cabinet 1 and accelerate the air cooling speed in the cabinet 1.

[0084] In some embodiments, the second mounting mechanism 5 is provided with a moving and static contact 7 on one side of the cabinet 1, the moving and static contact 7 penetrates the cabinet 1 and a second temperature sensor 8 is installed on the cabinet 1 located above the moving and static contact 7, and the second sensor is electrically connected to the industrial control machine;

[0085] The moving and stationary contacts 7 include a housing 71 and a connecting piece 72 mounted on the outer side of the housing 71 . The connecting piece 72 is fixedly connected to the second mounting mechanism 5 . A plurality of one-way valve pieces 73 are arranged on the connecting piece 72 .

[0086] When the second temperature sensor 8 detects abnormal temperature, the entire start-up control mechanism 3 is simultaneously in the third gear mode of the fan 22, and the closing component 55 between the third air collecting hood 543 and the second air collecting hood 542 is closed. At this time, the air pressure on the inside of the mounting plate 52 from the outside is greatly increased, and the one-way valve 73 is opened. The outside air passes through the outer shell 71 and the one-way valve 73 into the inside of the mounting plate 52, and the high-speed flowing cold air flows through the contacts, thereby achieving a rapid cooling effect, further avoiding large-scale power outages caused by excessive temperature rise and explosion of electrical equipment.
