Description

Technical Field

[0001] The present invention relates to the field of metal-enclosed switchgear, and more particularly, to an environmentally friendly gas-insulated AC metal-enclosed switchgear. Background Art

[0002] A gas-insulated AC metal-enclosed switchgear is a switchgear that uses low-pressure SF6 gas, N2 gas, or a mixed gas as an insulating medium, and uses vacuum or SF6 as an arc-extinguishing medium to centrally enclose medium-voltage components such as busbars, circuit breakers, and disconnectors in a metal box.

[0003] It mainly utilizes the excellent insulating properties of the insulating gas to keep reliable insulation between the live parts in the switchgear and between the live parts and the grounded parts. When the circuit needs to be connected or disconnected, it is achieved by operating switch elements such as circuit breakers and disconnectors. For example, during normal operation, current is transmitted through the busbar to each circuit, and the circuit breaker is in the closed state to ensure normal power supply; when a fault occurs in the line, the protection device operates to trip the circuit breaker and cut off the fault current, playing a protective role.

[0004] The "environmentally friendly gas-insulated AC metal-enclosed switchgear" disclosed in the Chinese invention patent has its specification disclose that: during actual operation, the electrical components in the switchgear generate heat during operation, which causes the temperature inside the switchgear to rise. The enclosed setting of the switchgear makes it difficult for the heat to dissipate, and the accumulated heat in the switchgear will cause the air pressure inside the cabinet to continuously rise, which in turn causes the cabinet to expand or even explode, posing a great safety hazard; the above patent can prove the defects existing in the prior art. However, in the process of solving its defects, the above patent only solves its heat dissipation problem, and does not address the cause of heat dissipation and the influence of heat dissipation according to the change of electric field strength.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0050] As described in the background art, the heat accumulation in the switch cabinet will cause the air pressure in the cabinet to continuously increase, which will further cause the cabinet to expand or even explode and cause the problem of electric field strength change.

[0051] In order to enable those skilled in the art of this technology to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0052] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0053] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0054] An environmentally friendly gas-insulated AC metal-enclosed switchgear, a heat dissipation plate 101, which is curved, and a push plate 102 is fixedly connected to the opening. A bellows 103 is fixedly connected to the surface of the push plate 102 away from the heat dissipation plate 101. A movable rod 104 is fixedly connected to the inner wall of the bellows 103. The other end of the movable rod 104 is fixedly connected to a sealing block 105.

[0055] A movable plate, one side of which is fixedly connected to the sealing block 105, and an adjusting plate 106 is hinged to the surface away from the sealing block 105. The adjusting plate 106 is inclined, and a first spring 107 is fixedly connected between the two adjusting plates 106.

[0056] A sealing pipe 108, one end of which is communicated with the bellows 103, and the sealing block 105 is slidably connected to its inner wall. The other end of the sealing pipe 108 is communicated with a connecting pipe 109. The other end of the connecting pipe 109 is communicated with a movable plate 110, and the movable plate rotates inside it. The end of the movable plate 110 away from the connecting pipe 109 is communicated with an adjusting pipe 111, and the adjusting plate 106 rotates inside it.

[0057] A cover plate 112 is fixedly connected to the surface of the heat dissipation plate 101 away from the bellows 103. A second spring 113 is fixedly connected to the surface of the cover plate 112 close to the heat dissipation plate 101, and the second spring 113 is fixedly connected to a diversion plate.

[0058] A heat conducting plate 114 is hinged to the heat dissipation plate 101.

[0059] A limiting plate 116 is hinged to the heat dissipation plate 101 and the heat conducting plate 114, and a slot 115 is arranged on its outer surface.

[0060] When adjusting the electric field strength inside the cabinet body, the bending degree of the heat dissipation plate 101 can be changed by rotating it to change the shape of the conductor, so as to realize the adjustment of the electric field strength. In addition, the rotation of the heat dissipation plate 101 can realize the adjustment of the air pressure inside the cabinet body and the purification and circulation of the gas.

[0061] During adjustment, the gas entering the interior of the closed adjustment tube 111 presses against the adjustment plate 106. After being pressed, the adjustment plate 106 rotates. The rotating adjustment plate 106 pushes the movable plate hinged to it, and drives the sealing block 105 to slide during the pushing process. Since the sealing block 105 is slidably connected inside the bellows 103, the movable rod 104 is fixedly connected to the bellows 103, and at the same time the sealing block 105 is fixedly connected to the bellows 103. The sliding of the sealing block 105 squeezes the bellows 103 by the movable rod 104, and drives the push plate 102 to slide during the squeezing process, and drives the heat dissipation plate 101 to bend during the sliding process. In some cases, the heat dissipation plate 101 is set as a rubber plate for bending. In the initial state, the heat dissipation plate 101 is in contact with the cover plate 112. When the heat dissipation plate 101 bends, it drives the cover plate 112 to rotate with it. During the rotation of the cover plate 112, the contact part thereof decreases, thereby reducing the thickness of the heat dissipation plate 101 and the cover plate 112, and thus realizing the change of the conductor thickness. At the same time, after the heat dissipation plate 101 bends, the radius of the conductor can be increased, thereby realizing the adjustment of the electric field strength. In addition, when the baffle bends, a negative pressure is realized inside the cabinet body, and the high-temperature gas moves towards the bent part and is transported through the heat dissipation slots 501 on the heat dissipation plate 101 to the heat exchange tube 205 for heat exchange. During the bending process of the heat dissipation plate 101, it can drive the heat conduction plate 114 hinged to it to rotate. At the same time, the gas can be discharged along the slot 115 on the limiting plate 116 to the heat exchange tube 205.

[0062] The upper surface of the adjustment tube 111 is communicated with an air delivery tube 201. The air delivery tube 201 is divided into multiple sections, and the other end is communicated with a separator 202. The upper surface of the separator 202 is communicated with an air pump 203. The input end of the air pump 203 is fixedly connected with a connecting frame 204, and a heat exchange tube 205 is installed on the upper surface of the connecting frame 204.

[0063] The air delivery tube 201 communicated with the upper surface of the adjustment tube 111 is used to transport the cooled gas to the adjustment tube 111 to rotate the adjustment plate 106 inside the control adjustment tube 111, so as to realize the adjustment of the bending degree of the heat dissipation plate 101. The air pump 203 communicated with the upper surface of the separator 202 is used to generate high-speed rotation of the cooled gas so as to enter the separator 202 for gas-liquid separation to ensure the dryness of the output gas and prevent the moisture in the gas from affecting the operation of electronic components. The connecting frame 204 fixedly connected to the input end of the air pump 203 fixes the heat exchange tube 205, and the heat exchange tube 205 installed on the upper surface of the connecting frame 204 is used for heat exchange cooling of the gas.

[0064] The lower surface of the regulating pipe 111 is connected to a regulating valve 301. The regulating valve 301 includes an intelligent gas emission control system, which includes an electric field intensity sensing module, a temperature sensing module, a gas pressure sensing module, a processing module, and an execution module. The electric field intensity sensing module, the temperature sensing module, and the gas pressure sensing module are connected in series and then in series with the processing module. The electric field intensity sensing module, the temperature sensing module, and the gas pressure sensing module are respectively used to monitor the electric field intensity, temperature, and gas pressure. The processing module is used to process the collected data, and the execution module is used to control the opening and closing of the regulating valve 301.

[0065] When controlling the opening and closing of the regulating valve 301, it needs to be adjusted according to the external environment, including temperature, gas pressure, and electric field intensity. The specific adjustment process is as follows:

[0066] The electric field intensity sensing module, the temperature sensing module, and the gas pressure sensing module collect the external electric field intensity, temperature, and gas pressure data and transmit them to the processing module for data processing. After the processing is completed, the adjustment is made according to the predetermined data, and the execution module is driven to open and close the regulating valve 301, and it is in dynamic monitoring.

[0067] Step 1: Multiphysics coupling modeling

[0068] Establish a dynamic relationship:

[0074] Step 2: Risk threshold determination

[0075] Safety range:

[0076] Dangerous action : when T>TmaxT>Tmax and E / pE / p When exceeding the limit, forcibly close the gas valve

[0077] Step 3: Dynamic adjustment of the gas valve

[0080] F(E,T,p) : Output of the fuzzy rule base (such as "high temperature + low gas pressure → increase the opening degree")

[0081] β: Electric field weight coefficient (default 0.3).

[0082] On the surface of the heat dissipation plate 101 close to the corrugated pipe 103, there are several heat dissipation grooves 501. On the inner wall of the opening of the heat dissipation plate 101 and on the upper surface, there is a ventilation plate 502 fixedly connected. The two ends of the ventilation plate 502 are connected and are bent.

[0083] The several heat dissipation grooves 501 provided on the surface of the heat dissipation plate 101 close to the corrugated pipe 103 are used to collect high-temperature gas. The collected gas enters the heat exchange pipe 205 along the ventilation plate 502 for cooling. In addition, the ventilation plate 502 is set to have both ends connected and be bent to facilitate the collection of gas.

[0084] The separator 202 includes a housing 601. An air inlet 602 is provided on the upper surface of the housing 601. An exhaust port 603 is provided on the side surface of the housing 601. The exhaust port 603 is communicated with the gas transmission pipe 201. A connecting ring 604 is fixedly connected to the surface of the housing 601 away from the exhaust port 603.

[0085] The air inlet 602 provided on the upper surface of the housing 601 is used for feeding the cooled gas. The exhaust port 603 provided on the side surface of the housing 601 is used for discharging the separated gas. The connecting ring 604 fixedly connected to the surface of the housing 601 away from the exhaust port 603 facilitates the installation of the rotating plate 701.

[0086] The inner surface of the connecting ring 604 is rotatably connected with a rotating plate 701. The rotating plate 701 is inclined and a conical block 702 is fixedly connected to the other surface. The conical block 702 shrinks from the middle to both ends and is conical. A blanking cylinder 703 is installed on the lower surface of the conical block 702.

[0087] The rotating plate 701 rotatably connected to the inner surface of the connecting ring 604 can realize the separation of gas by rotation. During separation, the high-speed blowing gas rotates the rotating plate 701 by blowing. The rotating rotating plate 701 drives the separation of gas and liquid. The separated liquid is discharged along the conical block 702 to the blanking cylinder 703 for collection, while the separated gas enters the gas transmission pipe 201 through the exhaust port 603 and is discharged.

[0088] The lower surface of the regulating valve 301 is communicated with an exhaust cylinder 801. A number of heat dissipation holes 802 are annularly arrayed on the outer surface of the exhaust cylinder 801.

[0089] The exhaust pipe 801 connected to the lower surface of the regulating valve 301 is used to discharge the cooled gas for heat dissipation. The heat dissipation holes 802 arranged in an annular array on the outer surface of the exhaust pipe 801 discharge the cooled gas inside the exhaust pipe 801. A sliding plate 901 is fixedly connected to the upper surface of the heat dissipation plate 101. The sliding plate 901 is slidably connected to the surface away from the heat dissipation plate 101 with an outer box 902. A fixing plate 903 is fixedly connected to the surface of the outer box 902 close to the heat dissipation plate 101. The fixing plate 903 is slidably connected to the heat dissipation plate 101 and is perpendicular to each other.

[0090] The sliding plate 901 fixedly connected to the upper surface of the heat dissipation plate 101 can adapt to the bending of the heat dissipation plate 101 by sliding, so as to seal the heat dissipation plate 101 and the outer box 902 during bending. In addition, during the bending process of the heat dissipation plate 101, the fixing plate 903 slidably connected to it simultaneously seals the heat dissipation plate 101 and the outer box 902.

[0091] An outer cabinet 904 is connected to the upper surface of the outer box 902. An instrument room 905 is installed on the upper surface of the outer cabinet 904. A circuit breaker room 906 is electrically connected to the lower surface of the instrument room 905. The circuit breaker room 906 is electrically connected to a cable room 907.

[0092] The outer cabinet 904 connected to the upper surface of the outer box 902 is used to install the internal structure of the cabinet. The instrument room 905 inside it is equipped with measuring instruments such as ammeters, voltmeters, wattmeters, and watt-hour meters, which can measure parameters such as current, voltage, power, and electric energy in the circuit in real time, helping operation and maintenance personnel to master the operating state of the power system. For example, the line load condition can be judged by observing the value of the ammeter. Equipment status indication: Devices such as indicator lights and live-line displays can directly display the opening and closing states of primary equipment such as circuit breakers and disconnectors and whether the line is energized. When the circuit breaker is closed, the corresponding indicator light lights up; the live-line display allows operation and maintenance personnel to clearly know whether there is high voltage on the line, ensuring personnel safety; the circuit breaker room 906 provides a special installation space for the circuit breaker. There are specific rails in the room to facilitate the sliding and fixing of the circuit breaker trolley, ensuring that the trolley can move between the working position, test position, and isolation position, and ensuring that the moving and static contacts are automatically centered and in good contact; the cable room 907 provides connection ports to facilitate the electrical connection of cables to internal electrical components of the switchgear such as circuit breakers and busbars, realizing the transmission and distribution of electric energy.

[0093] The usage process of an environmentally friendly gas-insulated AC metal-enclosed switchgear provided by the present invention is as follows:

[0094] When adjusting the electric field intensity inside the cabinet, the bending degree of the heat dissipation plate 101 can be changed by rotating the heat dissipation plate 101 to change the shape of the conductor, thereby realizing the adjustment of the electric field intensity. In addition, the rotation of the heat dissipation plate 101 can realize the adjustment of the air pressure inside the cabinet and the purification and circulation of the gas;

[0095] During adjustment, the gas entering the inside of the closed adjustment pipe 111 squeezes the adjustment plate 106. After being squeezed, the adjustment plate 106 rotates. The rotating adjustment plate 106 pushes the movable plate hinged to it, and drives the sealing block 105 to slide during the pushing process. Since the sealing block 105 is slidably connected inside the corrugated pipe 103, the movable rod 104 is fixedly connected to the corrugated pipe 103, and at the same time the sealing block 105 is fixedly connected to the corrugated pipe 103. The sliding of the sealing block 105 squeezes the corrugated pipe 103 by the movable rod 104, and drives the push plate 102 to slide during the squeezing process, and drives the heat dissipation plate 101 to bend during the sliding process. In some cases, the heat dissipation plate 101 is set as a rubber plate for bending. In the initial state, the heat dissipation plate 101 is in body contact with the cover plate 112. When the heat dissipation plate 101 bends, it drives the cover plate 112 to rotate with it. During the rotation of the cover plate 112, the fitting part thereof decreases, thereby reducing the thickness of the heat dissipation plate 101 and the cover plate 112, and then realizing the change of the conductor thickness. At the same time, after the heat dissipation plate 101 bends, the radius of the conductor can be increased, thereby realizing the adjustment of the electric field strength. In addition, when the baffle bends, a negative pressure is realized inside the cabinet body, and the high-temperature gas moves towards the bent part and is transported through the heat dissipation slots 501 on the heat dissipation plate 101 to the heat exchange pipe 205 for heat exchange. During the bending process of the heat dissipation plate 101, it can drive the heat conduction plate 114 hinged to it to rotate. At the same time, the gas can be discharged along the slot 115 on the limiting plate 116 to the heat exchange pipe 205;

[0096] The rotating plate 701 rotatably connected to the inner surface of the connecting ring 604 can separate the gas by rotation. During separation, the high-speed blowing gas rotates by blowing the rotating plate 701. The rotating rotating plate 701 drives the gas and the liquid to separate. The separated liquid is discharged along the conical block 702 to the blanking cylinder 703 for collection, and the separated gas enters the gas transmission pipe 201 through the exhaust port 603 and is discharged.
