Description

Technical Field

[0001] The invention relates to the technical field of temperature monitoring of power grid simulation equipment, in particular to a power grid simulation equipment with a wide-area temperature measurement and regulation mechanism. Background Art

[0002] Grid simulation equipment plays a key role in the design, testing, optimization and training of power systems. It simulates the steady-state and transient conditions of the power grid, such as short circuit, harmonics, and frequency fluctuations; tests the performance and reliability of new equipment, such as protection relays, inverters, and DC circuit breakers; verifies the action logic of the protection system through fault simulation, such as ground short circuit and line break, to avoid chain failures caused by protection misoperation and refusal in the actual power grid. Most of the current grid simulation equipment is coordinated with wind power and photovoltaic power generation networks, because the installation locations of wind power and photovoltaic power generation networks are mostly in vast areas with high humidity, high corrosion, and strong wind and sand. In order to improve the safety and durability of the equipment, it is necessary to install an equipment protection box outside it, which seriously reduces its overall heat dissipation effect. The internal temperature measurement unit of the equipment is simply used for recording. The temperature measurement position is fixed and limited, and it is impossible to quickly record the local temperature of different internal locations, nor can it automatically adjust the heat dissipation method and efficiency according to the difference in local temperature, resulting in uneven internal temperature. Summary of the invention

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A power grid simulation device with a wide-area temperature measurement and control mechanism is shown, comprising an external protection box 1 and a power grid simulation device body 2 installed inside the external protection box 1, symmetrical side flip openings 3 are opened on the outer walls on both sides of the external protection box 1, and an electrically controlled flip heat-converting liquid tank 4 is movably installed inside the side flip opening 3, and a first heat exchange channel 5 and a second heat exchange channel 6 with a serpentine structure for cooperating with top heat dissipation are fixedly installed on the top surface of the inner top of the external protection box 1, and a plurality of horizontally arranged reinforcing ridges 7 are provided on the upper surface of the external protection box 1, and a plurality of top air vents 8 are staggeredly opened on the upper end of the reinforcing ridges 7 on the upper surface of the external protection box 1, and an electrically controlled flip measurement and control mechanism 9 cooperating with the first heat exchange channel 5 and the second heat exchange channel 6 is provided on the top air vent 8.

[0024] Working principle: The electric-controlled flip heat-exchange liquid tank 4 on one side is driven to the first heat exchange channel 5, and then introduced from the first heat exchange channel 5 to the electric-controlled flip heat-exchange liquid tank 4 on the other side to reset the temperature, and then introduced to the second heat exchange channel 6, and then guided back to the electric-controlled flip heat-exchange liquid tank 4 on the initial side through the second heat exchange channel 6, so that the temperature of the inflow liquid and the return liquid can be kept consistent, thereby ensuring the stability and accuracy of the temperature measurement. The operating status of the internal simulation equipment can be judged through the numerical changes of the top temperature measurement, which is convenient for timely understanding of the operating status of the internal equipment, and convenient for rapid processing when a fault occurs, thereby improving the safety and stability of the equipment operation.

[0025] To facilitate lateral maintenance, the electrically controlled flip hot liquid tank 4 includes an external closing plate 41 hingedly connected to the outside of the opening of the lateral flip port 3, a side-mounted box body 42 fixed on the inner side of the external closing plate 41, and an electrically controlled lateral support rod 43 movably installed on the inner opening of the lateral flip port 3.

[0026] By arranging the top corners of the heat exchange liquid box, the utilization effect of the internal space can be greatly improved, and it is also convenient to operate. An electric control liquid pump is installed inside the side-mounted box 42. The electric control liquid pump drives the internal heat exchange liquid to flow inside the first heat exchange flow channel 5 and the second heat exchange flow channel 6.

[0027] The flipping angle of the external closing plate 41 is controlled by retracting the electrically controlled lateral support rod 43, thereby controlling the side-mounted box 42 to flip outward. The advantage is that it can not only improve the overall heat dissipation effect of the side-mounted box 42 when the internal temperature is high, but also facilitate the maintenance of the side-mounted box 42 after it is flipped outward.

[0028] In order to facilitate flow diversion, a first flow guide pipe 44 for connecting to the first heat exchange channel 5 and a second flow guide pipe 45 for connecting to the second heat exchange channel 6 are fixedly mounted on the upper end of the side-mounted box body 42 .

[0029] The first flow guide pipe 44 and the second flow guide pipe 45 are used to control the liquid outflow and liquid return respectively. The liquid outflow and liquid return modes are specifically adjusted by the side-mounted boxes 42 at different positions.

[0030] In order to facilitate the connection and control, the first heat exchange channel 5 and the second heat exchange channel 6 are axially fixed with an end connecting pipe 10 at the connection end of the electrically controlled flip-type measurement and control mechanism 9.

[0031] By mounting a fixed end connecting pipe 10 on the port, a plurality of first heat exchange channels 5 or a plurality of second heat exchange channels 6 can be connected in series to form an integral channel.

[0032] In order to cooperate with internal temperature measurement and adjustment control, the electrically controlled flip measurement and control mechanism 9 includes a temperature sensing module 91 fixed in the end connecting tube 10, an external adjustment sealing cover 92 slidably sleeved on the outside of the end connecting tube 10, an external flow guide tube 93 fixed on the outside of the external adjustment sealing cover 92, an external closed cover plate 94 elastically sleeved on the horizontal section of the external flow guide tube 93, and an electrically controlled worm gear assembly fixedly installed on the outer side of the external adjustment sealing cover 92.

[0033] The temperature sensing module 91 is used to detect the temperature of the liquid introduced into the end connecting tube 10. The temperature sensing module 91 can measure the liquid temperature at the inlet of the end connecting tube 10. When the temperature exceeds the set maximum temperature value, or the local temperature is greater than the adjacent temperature, the electronically controlled worm gear assembly will be controlled to start, thereby controlling the external adjustment sealing cover 92 and the external guide tube 93 outside it to flip, and then drive the external closed cover plate 94 outside the external guide tube 93 to flip outward, thereby opening the top air vent 8 located at the upper end of the reinforcing ridge 7, and the fluid introduced into the end connecting tube 10 is accelerated to dissipate heat through the external guide tube 93, thereby quickly adjusting the internal temperature and improving the top heat dissipation effect.

[0034] In order to cooperate with internal isolation and diversion, an internal isolation plate 12 with a diversion hole 11 is fixedly assembled inside the end connecting tube 10, and an inner sealing plate 13 for flipping and closing the diversion hole 11 is provided on the inner wall of the external diversion tube 93.

[0035] The temperature sensing module 91 is fixedly mounted on the side wall of the internal isolation plate 12 and adopts an embedded structure design.

[0036] The inner sealing plate 13 isolates the interior of the outer flow guide tube 93 into an N-shaped flow channel.

[0037] When the external adjustment sealing cover 92 is flipped, the inner sealing plate 13 is synchronously controlled to close or open the flow guide hole 11. When the inner sealing plate 13 closes the flow guide hole 11, the fluid inside the end connecting tube 10 will be introduced into the external flow guide tube 93 through the inner sealing plate 13, and will flow back to the other end of the internal isolation plate 12 through the N-shaped flow channel inside the external flow guide tube 93.

[0038] In order to cooperate with the angle adjustment control, the electrically controlled worm gear assembly includes an annular worm gear 95 fixed on the outer arc surface of the end connecting tube 10, an external drive chamber 96 fixed on the outer arc surface of the external adjustment sealing cover 92, and an electrically controlled worm 97 installed inside the external drive chamber 96.

[0039] The electrically controlled worm 97 meshes with the annular worm gear 95 , and the electrically controlled worm 97 is used to rotate and adjust the external adjustment sealing cover 92 outside the end connecting pipe 10 , thereby changing the angle of the external guide tube 93 located outside the external adjustment sealing cover 92 .

[0040] In order to facilitate the feeding and discharging of materials into the side-mounted box body 42, the lower end of the side-mounted box body 42 is provided with a bottom water supply nozzle 46 and a bottom water inlet nozzle 47, and the outer side threads of the bottom water supply nozzle 46 and the bottom water inlet nozzle 47 are equipped with an internal thread sealing cover 48.

[0041] A one-way check valve is provided inside the bottom water inlet nozzle 47, which can introduce heat exchange liquid inward but cannot discharge it, so that it is convenient to connect the liquid delivery pipe.

[0042] In order to cooperate with the bottom side air guide, strip-shaped guide holes are opened on the outer walls of both sides of the external protection box body 1, and an electrically controlled closing cover plate 14 is movably installed at the outer opening position of the strip-shaped guide holes on the outer side of the external protection box body 1.

[0043] In order to cooperate with the bottom side flip control and ensure the bottom air intake and air cleanliness, the electrically controlled closed cover 14 includes an outer closed cover 141 hingedly connected to the outside of the external protective box 1, an arc-shaped linkage rod 142 fixed on the inner side of the external closed cover 141, a linkage mesh frame 143 located inside the external protective box 1, a detachable adsorption block 144 filled in the linkage mesh frame 143 and an inner control motor 145 for controlling the arc-shaped linkage rod 142.

[0044] The inner control motor 145 meshes with the tooth surface on the arc surface of the arc linkage rod 142 through the control gears on the control shafts on both sides, thereby controlling the arc linkage rod 142 to adjust the movement. When bottom air intake is required, the arc linkage rod 142 controls the linkage net frame 143 to fit the inner opening of the strip guide hole, and the outer closing cover plate 141 flips outward, thereby preventing rainwater from the upper end from flowing into the strip guide hole and not affecting the air drawn into the outer protective box 1; when the bottom needs to be closed, the arc linkage rod 142 controls the outer closing cover plate 141 to fit the outer opening of the strip guide hole, thereby completely closing the strip guide hole.

[0045] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
