Description

Technical Field

[0001] The invention relates to the technical field of transformer substations, in particular to a box-type transformer substation with an emergency fire extinguishing function for a wind farm. Background Art

[0002] The box-type substation is a kind of factory-prefabricated indoor and outdoor compact distribution equipment that integrates high-voltage switchgear, distribution transformers and low-voltage distribution devices according to a certain wiring scheme. It organically combines the functions of transformer step-down and low-voltage distribution, and is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed, movable steel structure box. It is particularly suitable for urban network construction and transformation. It is a new type of substation that has emerged after the civil construction substation. The box-type substation is suitable for mines, factories, enterprises, oil and gas fields and wind power stations. It replaces the original civil construction distribution room and distribution station and becomes a new type of complete set of transformer and distribution equipment; The existing box-type substations installed in wind farms usually do not have relevant emergency fire extinguishing functions. Once a short circuit causes a fire, the only thing left is to wait for the fire to burn out the entire substation and extinguish itself. At the same time, the wind farm is located in a remote area and is unattended most of the time. After a fire occurs, it is impossible to arrive and extinguish the fire in time, resulting in greater losses to the box-type substation. Summary of the invention

[0010] Preferably, an air slot is provided on the top of the machine body, a plurality of wind wheels are provided in the air slot, the wind wheels are equidistantly arranged along the sides of the air slot, the wind wheel is provided between two air inlet groups, the wind wheel is rotatably connected to the air slot, an energy storage box is provided at the bottom of the fixed block, a generator is provided at the bottom of the wind wheel, and the generator is connected to the energy storage box through electric wires.

[0011] Preferably, a plurality of power components are arranged in the body, and a gap is arranged between two of the power components.

[0012] Since the box-type substation is set in the wind farm, the side of the box-type substation facing the wind direction is the windward side. When the wind blows towards the box-type substation, the wind drives the wind vane and anemometer on the top of the machine body to rotate. If the wind direction changes, the wind vane will deflect under the action of the wind, and the angle sensor on the wind vane will convert the deflection angle signal of the wind vane into an electrical signal and transmit it to the controller. Then the controller controls the drive motor to start, and the drive shaft of the drive motor drives the rotating column to rotate, and then the rotating column drives the machine body to deflect, and the angle inside the machine body changes. The sensor detects the deflection angle of the machine body, converts the deflection angle signal into an electrical signal, and transmits it to the controller, so that the controller compares the deflection angle signal of the machine body with the deflection angle signal of the wind vane. When the deflection angle signal of the machine body is the same as the deflection angle signal of the wind vane, the wind direction is perpendicular to the windward side of the machine body. Through the deflection of the wind vane, the rotating column drives the machine body to deflect, so that the box-type substation is always perpendicular to the wind direction, the contact area between the wind and the machine body is increased, and the heat generated by the substation is taken away; Since a rotating column and an arc block are arranged between the machine body and the fixed block, there is a gap between the machine body and the fixed block, that is, the machine body is separated from the ground. When precipitation occurs, it prevents rainwater from accumulating on the surface of the fixed block and eroding the surface of the machine body, thereby extending the protective life of the machine body; Since the windward surface of the machine body is always in a perpendicular state to the wind direction, the heat dissipation slots arranged on both sides of the machine body are always in a parallel state to the wind direction, and the wind passes through the heat dissipation slots during the flow. Since the area of ​​the end surfaces at both ends of the heat dissipation slots is larger than the area of ​​the central cross section of the heat dissipation slots, that is, the heat dissipation slots are thick at both ends and thin in the middle, when the wind flows through the heat dissipation slots, the flow speed in the middle of the heat dissipation slots is the fastest, and the air pressure in the middle of the heat dissipation slots is the smallest. Since the airflow velocity in the machine body is relatively low, the airflow in the machine body will flow to the side close to the heat dissipation holes under the action of air pressure, and then flow to the heat dissipation slots through the heat dissipation holes. Since a number of power components are arranged, the heat generated by the power components is transported to the heat dissipation slots along with the airflow in the machine body, thereby taking away the heat in the machine body, thereby achieving the heat dissipation effect. When the box-type substation is operating normally, the direction of the air inlet is opposite to the wind direction, and the wind is transported to the air inlet during the flow process, and the wind flows through the air inlet to the air guide slot, and is transported to the connection port through the air guide slot, and finally transports air into the machine body through the connection port, so as to use the outside air to dissipate the heat of the power components. At this time, the wind shield is retracted into the rotating slot, the electromagnetic coil in the ring slot is also in a power-off state, and the baffle plate is parallel to the cross-section of the machine body, and the intervals between several power components are in a connected state, so that the flow range of the gas is expanded, and the contact area between the power components and the heat dissipation air is increased, thereby improving the heat dissipation efficiency of the machine body; When a power component short-circuits and causes a fire, the temperature sensor in the machine body converts the temperature signal in the machine body into an electrical signal and transmits it to the controller. The controller then controls the movement of the surrounding barrier plates in the power component, and the drive shaft of the No. 2 micro motor drives the friction wheel to rotate. When the friction wheel rotates, it makes friction contact with the L-shaped slide groove, and then the friction wheel drives the barrier plate to move along the L-shaped slide groove, and then the two barrier plates change from a state where the barrier plates and the cross-section of the machine body are parallel to each other to a state where the barrier plates and the cross-section of the machine body are perpendicular to each other, and then the barrier plates and the machine body isolate and seal the power component where the fire occurs; At the same time, the controller controls the electromagnetic coil in the annular groove to start. After the electromagnetic coil is energized, it generates magnetic force, which attracts the magnetic conductor in the rotating blade, so that the magnetic conductor rotates under the action of the magnetic force, and the rotating blade rotates counterclockwise around the rotating axis. Since the power component where the fire occurs is blocked and sealed, the fire will cause the gas in the sealed space to expand, and then the gas flows to the annular groove through the connection port. Under the action of the rotating blades, the hot air flows to the ramp through the annular groove and is finally discharged through the air inlet. In the enclosed space, due to the discharge of the combustion aid and the continuous wind in the wind farm blowing towards the machine body, the heat of the machine body is taken away, which causes the heat in the enclosed area to decrease, so that the fire source in the enclosed space is gradually extinguished under the condition of lack of combustion aid and heat, thereby achieving the function of emergency fire extinguishing. When the wind flows through the body, it will also flow through the wind slot. In the process of flowing through the wind slot, the wind will drive the wind wheel to rotate, and then the rotation of the wind wheel will drive the generator at the bottom to generate electricity. The generated electricity is transmitted to the energy storage box through the circuit, thereby achieving a self-sufficient effect.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The direction of the wind is detected by using a wind vane, and the body is driven to rotate by a rotating column, so that the windward surface of the body 1 is perpendicular to the wind direction, and then the wind direction is parallel to the heat dissipation slot, that is, the contact area between the body and the wind is increased, and the heat exchange efficiency between the body and the wind is improved, and the wind can flow through the heat dissipation slot and accelerate the flow rate in the heat dissipation slot to take away the heat in the body, and the wind enters the body through the air inlet group, further improving the heat dissipation efficiency of the body, ensuring the smooth operation of the box-type substation, and a rotating column and an arc block are arranged between the body and the fixed block, and then there is a gap between the body and the fixed block, that is, the body is separated from the ground, when precipitation occurs, it avoids the erosion of the surface of the body by rainwater accumulation on the surface of the fixed block, thereby extending the protective life of the body.

[0014] 2. When a fire occurs in a box-type substation, the baffle plate and the inner wall of the machine body are used to seal the power components where the fire occurs, and the rotating blades are used to transport the combustion aid outward, so that the combustion aid content in the barrier space decreases, and the heat is taken away by the contact with the wind and the machine body. In the absence of combustion aid and heat, the speed of the fire spread is reduced, and finally it is extinguished by itself, thereby achieving the effect of emergency fire extinguishing, ensuring the normal operation of the remaining power components, and reducing the loss of the box-type substation.

[0015] 3. By setting up multiple power components in the box-type substation, the power components have working redundancy. When a power component fails or catches fire, the remaining power components can still support the normal operation of the box-type substation. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Working principle of the present invention: Since the box-type substation is arranged in the wind farm, the side of the box-type substation facing the wind direction is the windward side. When the wind blows towards the box-type substation, the wind drives the wind vane and anemometer on the top of the machine body 1 to rotate. If the wind direction changes, the wind vane will deflect under the action of the wind, and the angle sensor on the wind vane will convert the deflection angle signal of the wind vane into an electrical signal and transmit it to the controller, and then the controller controls the drive motor to start, and the drive shaft of the drive motor drives the rotating column 21 to rotate, and then the rotating column 21 drives the machine body 1 to deflect, and the angle inside the machine body 1 The sensor detects the deflection angle of the machine body 1, converts the deflection angle signal into an electrical signal, and transmits it to the controller, so that the controller compares the deflection angle signal of the machine body 1 with the deflection angle signal of the wind vane. When the deflection angle signal of the machine body 1 is the same as the deflection angle signal of the wind vane, the wind direction is perpendicular to the windward surface of the machine body 1. Through the deflection of the wind vane, the rotating column 21 drives the machine body 1 to deflect, so that the box-type substation is always perpendicular to the wind direction, the contact area between the wind and the machine body 1 is increased, and the heat generated by the substation is taken away; Since the rotating column 21 and the arc block 22 are arranged between the machine body 1 and the fixed block 11, there is a gap between the machine body 1 and the fixed block 11, that is, the machine body 1 is separated from the ground. When precipitation occurs, it is prevented that the rainwater accumulates on the surface of the fixed block 11 and erodes the surface of the machine body 1, thereby extending the protection life of the machine body 1; Since the windward surface of the machine body 1 is always in a perpendicular state to the wind direction, the heat dissipation slots 31 arranged on both sides of the machine body 1 are always in a parallel state to the wind direction, and the wind passes through the heat dissipation slots 31 during the flow. Since the area of ​​the end surfaces at both ends of the heat dissipation slots 31 is larger than the area of ​​the central cross section of the heat dissipation slots 31, that is, the heat dissipation slots 31 are thick at both ends and thin in the middle, when the wind flows through the heat dissipation slots 31, the flow speed in the middle of the heat dissipation slots 31 is the fastest, and the air pressure in the middle of the heat dissipation slots 31 is the smallest. Since the airflow velocity in the machine body 1 is relatively low, the airflow in the machine body 1 will flow to the side close to the heat dissipation holes 32 under the action of the air pressure, and then flow to the heat dissipation slots 31 through the heat dissipation holes 32. Since a plurality of power components 14 are provided, the heat generated by the power components 14 is transported to the heat dissipation slots 31 along with the airflow in the machine body 1, thereby taking away the heat in the machine body 1, thereby achieving the heat dissipation effect. When the box-type substation is operating normally, the direction of the air inlet 34 is opposite to the wind direction, and the wind is transported to the air inlet 34 during the flow, and the wind flows through the air inlet 34 to the air guide slot 35, and is transported to the connection port 36 through the air guide slot 35, and finally transports air into the body 1 through the connection port 36, so that the power component 14 is cooled by the outside air. At this time, the wind shield 354 is retracted into the rotating slot 353, the electromagnetic coil in the annular slot 352 is also in a power-off state, and the baffle plate 38 is parallel to the cross-section of the body 1, and the intervals between the several power components 14 are in a connected state, so that the flow range of the gas is expanded, and the contact area between the power component 14 and the cooling air is increased, thereby improving the heat dissipation efficiency of the body 1; When a power component 14 short-circuits and causes a fire, the temperature sensor in the body 1 converts the temperature signal in the body 1 into an electrical signal and transmits it to the controller. The controller then controls the movement of the surrounding barrier plates 38 in the power component 14, and the drive shaft of the second micro motor drives the friction wheel 381 to rotate. When the friction wheel 381 rotates, it makes friction contact with the L-shaped slide groove 37, and then the friction wheel 381 drives the barrier plates 38 to move along the L-shaped slide groove 37, and then the two barrier plates 38 are changed from a state in which the barrier plates 38 and the cross-section of the body 1 are parallel to each other to a state in which the barrier plates 38 and the cross-section of the body 1 are perpendicular to each other, and then the barrier plates 38 and the body 1 block and seal the power component 14 where the fire occurs; At the same time, the controller controls the electromagnetic coil in the annular groove 352 to start. After the electromagnetic coil is energized, it generates magnetic force, which attracts the magnetic conductor in the rotating blade 355, so that the magnetic conductor rotates under the action of the magnetic force, and the rotating blade 355 rotates counterclockwise around the rotation axis. Since the power component 14 where the fire occurs is blocked and sealed, the fire will cause the gas in the sealed space to expand, and then the gas flows to the annular groove 352 through the connecting port 36. Under the action of the rotating blade 355, the hot air flows to the ramp 351 through the annular groove 352, and is finally discharged through the air inlet 34. In the enclosed space, due to the discharge of the combustion aid and the continuous wind in the wind farm blowing toward the body 1, the heat of the body 1 is taken away, and the heat in the enclosed area is reduced accordingly, so that the fire source in the enclosed space is gradually extinguished under the condition of lack of combustion aid and heat, thereby achieving the function of emergency fire extinguishing. When the wind flows through the body 1, the wind will also flow through the wind slot 12. When the wind flows through the wind slot 12, the wind will drive the wind wheel 13 to rotate. When the wind wheel 13 rotates, it drives the generator at the bottom to generate electricity. The generated electricity is transmitted to the energy storage box through the circuit, thereby achieving a self-sufficient effect.
