Description

Technical Field

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

[0002] Power grid simulation equipment plays a key role in the design, testing, optimization and training of power systems. Its function is to simulate the steady-state and transient conditions of the power grid, such as short circuits, harmonics, and frequency fluctuations; test the performance and reliability of new equipment, such as protection relays, inverters, and DC circuit breakers; verify the action logic of the protection system through fault simulations, such as ground short circuits and broken wires, to avoid cascading failures caused by misoperation or refusal to operate of the protection in the actual power grid. Most current power grid simulation equipment is coordinated with wind power and photovoltaic power generation networks. Since the installation locations of wind power and photovoltaic power generation networks are mostly vast areas with high humidity, high corrosion, and large sand and dust, in order to improve the safety and durability of the equipment, an equipment protection box needs to be installed on its outside, which seriously reduces its overall heat dissipation effect. Inside, only a simple temperature measurement unit inside the equipment is used for recording. The temperature measurement positions are fixed and limited, and it is impossible to quickly record the local temperatures at different positions inside, nor can it automatically adjust the heat dissipation method and efficiency according to the differences in local temperatures, resulting in uneven internal temperatures. Summary of the Invention

[0028] The present invention will now be further described in detail with reference to the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0029] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "connected" 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 directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] 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 as shown, including an external protective box body 1 and a power grid simulation device body 2 installed inside the external protective box body 1. Symmetrically arranged lateral flipping ports 3 are opened on the outer walls of both sides of the external protective box body 1. An electronically controlled flipping heat exchange liquid box 4 is movably assembled inside the lateral flipping port 3. A first heat exchange flow channel 5 and a second heat exchange flow channel 6 in a serpentine structure for cooperating with top heat dissipation are fixedly installed on the inner top surface of the external protective box body 1. The upper surface of the external protective box body 1 has a plurality of horizontally arranged reinforcing ribs 7. A plurality of top ventilation ports 8 are staggeredly opened above the reinforcing ribs 7 on the upper surface of the external protective box body 1. An electronically controlled flipping measurement and control mechanism 9 that cooperates with the first heat exchange flow channel 5 and the second heat exchange flow channel 6 is arranged on the top ventilation port 8.

[0031] Working principle: The electronically controlled flipping heat exchange liquid box 4 on one side drives the liquid to the first heat exchange flow channel 5, and then is introduced from the first heat exchange flow channel 5 into the electronically controlled flipping heat exchange liquid box 4 on the other side for temperature reduction and reset, and then is introduced into the second heat exchange flow channel 6 and led back to the electronically controlled flipping heat exchange liquid box 4 on the initial side through the second heat exchange flow channel 6. In this way, the temperatures of the inflow liquid and the return liquid can be kept consistent, thus ensuring the stability and accuracy of temperature measurement. By the numerical change of the top temperature measurement, the operating state of the internal simulation device can be judged, which is convenient for timely understanding the operating state of the internal device, facilitating quick handling in case of a failure, and improving the safety and stability of the device operation.

[0032] For convenient lateral maintenance, the electronically controlled flipping heat exchange liquid box 4 includes an external closing plate 41 hinge-connected to the outside of the opening of the lateral flipping port 3, a side-hung box body 42 fixed to the inner side surface of the external closing plate 41, and an electronically controlled lateral strut 43 movably installed at the inner opening of the lateral flipping port 3.

[0033] By arranging the top corners of the heat exchange liquid box body, the utilization effect of the internal space can be greatly improved, and at the same time, it is convenient for operation. An electronically controlled liquid pumping pump is installed inside the side-hung box body 42. The electronically controlled liquid pumping pump is used to drive the internal heat exchange liquid to flow inside the first heat exchange flow channel 5 and the second heat exchange flow channel 6.

[0034] The flipping angle of the external closing plate 41 is controlled by the telescopic movement of the electric control side strut 43, so as to control the outward flipping of the side-mounted box body 42. The advantage is that not only can the overall heat dissipation effect of the side-mounted box body 42 be improved under the condition of high internal temperature, but also it is convenient to maintain the side-mounted box body 42 after it is flipped outward.

[0035] In order to cooperate with the diversion, a first diversion pipe 44 for connecting the first heat exchange flow path 5 and a second diversion pipe 45 for connecting the second heat exchange flow path 6 are fixedly assembled at the upper end of the side-mounted box body 42.

[0036] The first diversion pipe 44 and the second diversion pipe 45 are used to control the liquid outlet and return respectively, and the ways of liquid outlet and return are specifically adjusted by the side-mounted box bodies 42 at different positions.

[0037] In order to cooperate with the connection and control, an end connection pipe 10 is axially fixed at the connection end of the first heat exchange flow path 5 and the second heat exchange flow path 6 of the electric control flipping type measurement and control mechanism 9.

[0038] By sleeving and fixing the end connection pipe 10 on the port, multiple first heat exchange flow paths 5 or multiple second heat exchange flow paths 6 can be connected in series to form an integral flow path.

[0039] In order to cooperate with the internal temperature measurement and adjustment control, the electric control flipping type measurement and control mechanism 9 includes a temperature sensing module 91 fixed in the end connection pipe 10, an external adjustment sealing cover 92 slidably sleeved outside the end connection pipe 10, an external diversion pipe 93 fixed on the outside of the external adjustment sealing cover 92, an external closing cover plate 94 elastically sleeved on the horizontal section of the external diversion pipe 93, and an electric control worm and worm gear assembly fixedly installed on the outer side surface of the external adjustment sealing cover 92.

[0040] The temperature sensing module 91 is used to detect the temperature of the liquid introduced into the end connection pipe 10. Through the temperature sensing module 91, the temperature of the liquid at the inlet of the end connection pipe 10 can be measured. When the temperature exceeds the set maximum temperature value, or the local temperature is greater than the adjacent temperature, at this time, the electric control worm and worm gear assembly will be controlled to start, so as to control the flipping of the external adjustment sealing cover 92 and the external diversion pipe 93 on its outside, and then drive the external closing cover plate 94 outside the external diversion pipe 93 to flip outward, so as to open the top ventilation port 8 at the upper end of the reinforcing rib 7. The fluid introduced into the end connection pipe 10 is accelerated for heat dissipation through the external diversion pipe 93, so as to quickly adjust the internal temperature and improve the top heat dissipation effect.

[0041] In order to cooperate with the internal isolation and diversion, an internal isolation plate 12 with a flow through hole 11 inside is fixedly assembled inside the end connection pipe 10, and an inner sealing plate 13 for flipping and closing the flow through hole 11 is provided on the inner wall of the external diversion pipe 93.

[0042] The temperature sensing module 91 is fixedly installed on the side wall of the internal isolation plate 12 and is designed with an embedded structure at the same time.

[0043] The inner sealing plate 13 internally isolates the external diversion pipe 93 into an n-shaped flow channel.

[0044] When the external adjustment sealing cover 92 is flipped, the inner sealing plate 13 is synchronously controlled to close or open the diversion through hole 11. When the inner sealing plate 13 closes the diversion through hole 11, the fluid located inside the end connection pipe 10 will be introduced into the external diversion pipe 93 through the inner sealing plate 13 and flow back to the other end of the internal isolation plate 12 via the n-shaped flow channel inside the external diversion pipe 93.

[0045] To cooperate with the angle adjustment control, the electric control worm and worm gear assembly includes an annular worm wheel 95 fixed on the outer arc surface of the end connection pipe 10, an external drive chamber 96 fixed on the outer arc surface of the external adjustment sealing cover 92, and an electric control worm 97 installed inside the external drive chamber 96.

[0046] The electric control worm 97 meshes with the annular worm wheel 95. By rotating and adjusting the electric control worm 97, the external adjustment sealing cover 92 is controlled to rotate and adjust on the outer side of the end connection pipe 10, thereby changing the angle of the external diversion pipe 93 located on the outer side of the external adjustment sealing cover 92.

[0047] To cooperate with the feeding and discharging inside 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. The outer sides of the bottom water supply nozzle 46 and the bottom water inlet nozzle 47 are threadedly fitted with internal thread sealing caps 48.

[0048] A one-way check valve is arranged inside the bottom water inlet nozzle 47, which can introduce the heat exchange liquid inward but cannot discharge it, so as to facilitate the connection of the liquid delivery pipe.

[0049] To cooperate with the bottom side air conduction, strip-shaped diversion holes are opened on the outer walls of both sides of the external protection box body 1, and an electric control type closing cover plate 14 is movably assembled at the outer opening position of the strip-shaped diversion holes on the outer side of the external protection box body 1.

[0050] To cooperate with the bottom side flipping control and ensure the bottom air intake and the cleanliness of the air, the electric control type closing cover plate 14 includes an outer closing cover plate 141 hinged to the outer side of the external protection box body 1, an arc-shaped linkage rod 142 fixed on the inner side surface of the outer closing cover plate 141, a linkage mesh frame 143 located inside the external protection box body 1, a detachable adsorption block 144 filled inside the linkage mesh frame 143, and an inner control motor 145 for controlling the arc-shaped linkage rod 142.

[0051] The inner control motor 145 is engaged with the tooth surface on the arc surface of the arc linkage rod 142 through the control gears on both sides of the control shaft, so as to control the movement and adjustment of the arc linkage rod 142. When bottom air intake is required, the arc linkage rod 142 is used to control the linkage screen frame 143 to fit the inner opening of the strip-shaped diversion hole, and the external closing cover plate 141 is turned outwards, so as to prevent rainwater at the upper end from flowing into the strip-shaped diversion hole and not affecting the air being drawn into the external protection box body 1; when bottom closing is required, the arc linkage rod 142 is used to control the external closing cover plate 141 to fit the outer opening of the strip-shaped diversion hole, so as to completely close the strip-shaped diversion hole.

[0052] Inspired by the above ideal embodiments of the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
