Description

Technical Field

[0001] This invention relates to the field of electrical engineering and power equipment technology, specifically to an automated transformer based on electrical engineering. Background Technology

[0002] Transformers are indispensable core equipment in the field of electrical engineering, widely used in power transmission and distribution, industrial power supply, and rail transportation. During long-term operation, transformers are prone to localized overheating due to overload, insulation aging, poor contact, or inadequate heat dissipation. When the temperature continues to rise and cannot be effectively controlled, it may cause spontaneous combustion of the wire insulation or short circuit, resulting in smoke and flames.

[0003] Currently, while some transformers in existing technologies are equipped with temperature monitoring devices or cooling fans, they suffer from the following shortcomings: most transformers only have a single temperature control function and lack the ability to directly detect smoke and flames, making it impossible to identify the fire in its early stages; even if some transformers are equipped with fire extinguishing devices, the transformer's ventilation holes remain open during the fire extinguishing process, allowing external oxygen to continuously enter the tank, making it difficult for the extinguishing agent to completely extinguish the fire and increasing the risk of reignition; transformer fires are often accompanied by power outages, causing control system failures and preventing the fire extinguishing devices from activating properly; existing equipment lacks an effective early warning and classification mechanism, failing to notify personnel for maintenance in the early stages of a fault, often only being detected after open flames appear, missing the best opportunity for response. Therefore, we propose an automated transformer based on electrical engineering to solve the above-mentioned problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automated transformer based on electrical engineering, which solves the problems of limited monitoring methods, easy reignition after fire extinguishing, easy power outage and loss of control during fires, and lack of early warning in existing transformers.

[0040] Beneficial effects

[0041] This invention provides an automated transformer based on electrical engineering. Compared with existing technologies, it has the following advantages:

[0042] This automated transformer based on electrical engineering, through the collaborative monitoring of pre-detection unit, flame detection unit and electrical parameter detection unit, constructs a multi-dimensional sensing system of temperature, smoke, flame, voltage and current. It can accurately identify anomalies in the early stages of transformer overheating, insulation aging, overload and other faults, making up for the shortcomings of traditional equipment that only has single temperature control and cannot detect fires in the early stage, and significantly improving the comprehensiveness and timeliness of safety monitoring.

[0043] This invention adopts an integrated design of driving mechanism linkage fire extinguishing unit and shielding component. When a fire occurs, the fire extinguishing agent can be sprayed and the heat dissipation hole can be sealed by the baffle at the same time, effectively cutting off the oxygen supply in the box. This solves the problem of reignition caused by continuous oxygen supply in traditional fire extinguishing methods from the root, making fire extinguishing more thorough and protection more reliable.

[0044] This invention is equipped with a photovoltaic power supply unit, which consists of a photovoltaic panel, an energy storage battery and a power management module to form an uninterrupted power supply system. When the external power supply is normal, it automatically stores energy. When a fire breaks out, it can instantly switch the power supply to ensure that the control unit and the fire extinguishing actuator can still operate stably under extreme conditions, and completely eliminate the risk of loss of control due to power failure.

[0045] This invention utilizes a control unit to achieve hierarchical intelligent control. When there is no open flame, the alarm unit is activated and a remote warning is sent, facilitating early maintenance. In the event of an open flame, the fire extinguishing procedure is automatically initiated, requiring no manual intervention throughout the process. The overall structure is stable and responsive, significantly improving the automation level of transformers and making it suitable for unattended scenarios such as power transmission and distribution, and industrial power supply.

[0052] like Figure 1-4 As shown:

[0053] An automated transformer based on electrical engineering, comprising:

[0054] The enclosure 101 has ventilation holes 102 on both sides;

[0055] The transformer body 103 is installed inside the enclosure 101;

[0056] The crossbeam plate 107 is fixed to the top of the box 101;

[0057] The housing cover 109 is fixed to the top of the box 101, and the crossbeam plate 107 is located inside the housing cover 109;

[0058] The pre-detection unit 105 and the flame detection unit 106 are respectively installed on the lower surface of the crossbeam plate 107;

[0059] The alarm unit 108 and the control unit 112 are respectively fixed to the inner side wall of the housing cover 109;

[0060] The fire extinguishing unit 110 is fixed inside the housing 109. The output end of the fire extinguishing unit 110 is set corresponding to the transformer body 103, and the output end of the fire extinguishing unit 110 is equipped with a press valve. The fire extinguishing unit 110 is a suspended dry powder fire extinguisher or an aerosol fire extinguisher. The spray nozzle of the fire extinguishing unit 110 is set towards the winding area of ​​the transformer body 103. The pre-detection unit 105 includes a temperature sensor and a smoke sensor. The flame detection unit 106 is an ultraviolet flame sensor or an infrared flame sensor.

[0061] The drive mechanism 111 is fixed inside the housing cover 109. The drive mechanism 111 is a combination of an electromagnet, an electric push rod, or a drive motor and a lead screw and nut mechanism.

[0062] The shielding component 2 is integrated into the housing 101. The shielding component 2 includes:

[0063] Baffle 201 is used to seal the heat dissipation hole 102;

[0064] The first guide wheel seat 202 is fixedly installed inside the housing 101 near the baffle 201;

[0065] A connecting rope 203 is fixedly connected at one end to the top of the baffle 201, and the connecting rope 203 is wound around the first guide wheel seat 202;

[0066] The main rope 204 has one end fixedly connected to two sets of connecting ropes 203;

[0067] A toggle plate 206 is fixedly connected to the output end of the drive mechanism 111, and the toggle plate 206 is correspondingly set to the press valve of the fire extinguishing unit 110;

[0068] When the drive mechanism 111 retracts, it moves the actuating plate 206 to release the main rope 204, which in turn moves the baffle 201 downward through the connecting rope 203. The baffle 201 is slidably and sealed inside the housing 101 near the heat dissipation hole 102. The crossbeam plate 107 has an annular hole 205 through which the main rope 204 passes. The inner wall of the annular hole 205 is provided with multiple sets of ball bearings to reduce the frictional resistance when the main rope 204 passes through. A second guide wheel seat 207 is also fixed on the crossbeam plate 107. The second guide wheel seat 207 is used to limit and guide the main rope 204.

[0069] The control unit 112 is electrically connected to the pre-detection unit 105, the flame detection unit 106, the alarm unit 108, and the drive mechanism 111, respectively.

[0070] Control unit 112 is configured as follows:

[0071] When the pre-detection unit 105 detects an abnormal signal and the flame detection unit 106 does not detect a flame signal, the control alarm unit 108 issues an audible and visual warning signal. The alarm unit 108 is an audible and visual alarm, which is fixedly installed on the outer wall or top of the housing cover 109.

[0072] When the flame detection unit 106 detects a flame signal, it triggers the drive mechanism 111 to operate. The drive mechanism 111 simultaneously drives the press valve of the fire extinguishing unit 110 to open to spray the fire extinguishing agent and drives the shielding assembly 2 to operate.

[0073] Photovoltaic power supply unit 3, integrated on housing 109 and electrically connected to control unit 112, is used to continuously provide operating power when the external power supply to the transformer is interrupted. Photovoltaic power supply unit 3 includes:

[0074] The photovoltaic panel 301 is fixedly installed on the outside of the housing 109;

[0075] The energy storage battery 302 and the power management module 303 are respectively fixedly installed inside the housing cover 109;

[0076] The power management module 303 is electrically connected to the photovoltaic panel 301, the energy storage battery 302 and the control unit 112 respectively;

[0077] The photovoltaic power supply unit 3 also includes a switching module, which is integrated into the power management module 303. It is used to supply power from the external power supply when the external power supply to the transformer is normal, and to automatically switch to the energy storage battery 302 when the external power supply to the transformer is interrupted.

[0078] It also includes a communication module, which is electrically connected to the control unit 112 and fixed inside the housing 109 or outside the box 101. The communication module is used to send a warning signal to the remote monitoring terminal when the pre-detection unit 105 detects an abnormal signal and the flame detection unit 106 does not detect a flame signal.

[0079] It also includes an electrical parameter detection unit, which is installed on the transformer body 103 and electrically connected to the control unit 112, for detecting the voltage and current of the transformer body 103;

[0080] The control unit 112 is also configured to send an early warning signal to the remote monitoring terminal via the communication module when the voltage and current values ​​detected by the electrical parameter detection unit exceed the preset threshold, so as to prompt personnel to carry out maintenance.

[0081] In this implementation plan: the automated transformer based on electrical engineering, when in use, uses the control unit 112 as the core control component, and works in conjunction with the pre-detection unit 105, flame detection unit 106, alarm unit 108, drive mechanism 111, fire extinguishing unit 110, shielding component 2, photovoltaic power supply unit 3, communication module, and electrical parameter detection unit to achieve fully automatic safety protection. The workflow is as follows:

[0082] During normal system operation, the external mains power serves as the main power supply. The power management module 303 of the photovoltaic power supply unit 3 switches the power supply circuit to the external power source via a built-in switching module. Simultaneously, the photovoltaic panel 301 converts light energy into electrical energy, which is then regulated by the power management module 303 and stored in the energy storage battery 302 to complete the backup power reserve. At this time, the heat dissipation holes 102 on both sides of the enclosure 101 remain open, and the baffle 201 of the shading component 2 is in the retracted position. The heat generated by the transformer body 103 during operation is naturally dissipated through the heat dissipation holes 102. The pre-detection unit 105, the flame detection unit 106, and the electrical parameter detection unit continuously collect temperature, smoke, flame, voltage, and current signals and upload them to the control unit 112 in real time. The control unit 112 compares the signals with preset thresholds, and the system maintains a standby monitoring state.

[0083] When the pre-detection unit 105 detects excessive temperature or abnormal smoke concentration, and the flame detection unit 106 does not detect a flame signal, or the electrical parameter detection unit detects that the voltage or current exceeds the threshold, the system enters the early warning process. The control unit 112 immediately drives the alarm unit 108 to issue an audible and visual warning signal; at the same time, it sends the abnormal information to the remote monitoring terminal through the communication module. During this stage, the drive mechanism 111, the fire extinguishing unit 110, and the shielding assembly 2 do not operate, and the heat dissipation hole 102 remains open, without affecting the normal heat dissipation of the transformer.

[0084] When the flame detection unit 106 detects an open flame signal, the control unit 112 immediately initiates the fire extinguishing procedure. If the fire causes an interruption in external power supply, the switching module of the power management module 303 instantly switches to the energy storage battery 302 for power supply, ensuring that core components such as the control unit 112 and the drive mechanism 111 continue to operate.

[0085] The control unit 112 drives the drive mechanism 111 to retract, causing the toggle plate 206 at the output end to move synchronously. The toggle plate 206 performs two actions simultaneously: First, it presses the press valve of the fire extinguishing unit 110, causing the fire extinguishing agent to spray out from the spray nozzle and directly act on the winding area of ​​the transformer body 103 to quickly suppress the fire source; Second, it releases the main rope 204, which passes through the annular hole 205 of the crossbeam plate 107 and slides smoothly under the guidance and friction reduction action of the ball bearings on the inner wall of the annular hole 205 and the second guide wheel seat 207; The main rope 204 pulls the two sets of connecting ropes 203, which are reversed through the first guide wheel seat 202, causing the baffle 201 to slide down along the inner wall of the box 101 until the heat dissipation hole 102 is completely sealed, cutting off the passage for oxygen to enter the box 101 and preventing reignition.

[0086] After the fire is extinguished, the flame signal of the flame detection unit 106 disappears, the drive mechanism 111 remains in its current state, and the baffle 201 continues to seal the heat dissipation hole 102. The communication module uploads the fire extinguishing information to the remote monitoring terminal, prompting maintenance personnel to arrive on site. After maintenance is completed, the drive mechanism 111 and the baffle 201 are manually reset, the extinguishing agent of the fire extinguishing unit 110 is replaced, and the system returns to normal operation.

[0087] This solution, through the collaborative monitoring of the pre-detection unit 105, the flame detection unit 106 and the electrical parameter detection unit, constructs a multi-dimensional sensing system of temperature, smoke, flame, voltage and current. It can accurately identify anomalies in the early stages of transformer overheating, insulation aging, overload and other faults, making up for the shortcomings of traditional equipment that only has single temperature control and cannot detect fires in the early stage, and significantly improving the comprehensiveness and timeliness of safety monitoring.

[0088] The present invention adopts an integrated design of driving mechanism 111 linking fire extinguishing unit 110 and shielding component 2. When a fire occurs, the fire extinguishing agent can be sprayed and the baffle 201 can be used to seal the heat dissipation hole 102 simultaneously, effectively cutting off the oxygen supply in the box. This solves the problem of reignition caused by continuous oxygen intake in traditional fire extinguishing methods from the root, making fire extinguishing more thorough and protection more reliable.

[0089] The present invention is equipped with a photovoltaic power supply unit 3, which consists of a photovoltaic panel 301, an energy storage battery 302 and a power management module 303 to form an uninterrupted power supply system. When the external power supply is normal, it automatically stores energy. When the power supply is interrupted by a fire, it can switch the power supply instantly to ensure that the control unit 112 and the fire extinguishing actuator can still operate stably under extreme conditions, and completely eliminate the risk of loss of control due to power failure.

[0090] This invention utilizes the control unit 112 to achieve hierarchical intelligent control. When there is no open flame, the alarm unit 108 is activated and a remote warning is sent, facilitating early maintenance. When an open flame is detected, the fire extinguishing program is automatically initiated, requiring no manual intervention throughout the process. The overall structure is stable and responsive, significantly improving the automation level of transformers and making it suitable for unattended scenarios such as power transmission and distribution, and industrial power supply.

[0091] It should be noted that the control method of this invention is controlled by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

The power supply is also common knowledge in the art. Furthermore, this invention is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
