Technical Field

[0001] This utility model relates to the field of electrical technology, and in particular to a fast switching device for power supply in a gas system. Background Technology

[0002] The power supply in the gas system plays a crucial role in supplying power for the combustion of raw materials in the unit. Most of its high-voltage power supply systems adopt a two-stage standby and automatic transfer switching method to ensure power switching in case of an accident, which involves the use of a rapid power supply switching device for the gas system.

[0003] Currently, although the existing gas system power supply switching device ensures the power supply switching function in case of an accident, the switching process is prone to causing the low voltage protection of the gas high-voltage motor in the switching section to trip, which directly affects the stability of the gas and steam supply, forces the boiler to shut down, and the forced boiler fire extinguishing seriously affects the safe, continuous and stable operation of the unit.

[0004] Therefore, to address the issue that the aforementioned gas system power supply switching device is prone to tripping due to low voltage protection of the high-voltage motor during switching, directly affecting the stability of gas and steam supply, a fast power supply switching device for the gas system can be designed. This device can detect parameters such as voltage and current of the main power supply and backup power supply by setting up a power detection module and a switching control module. Based on the signal from the fault detection module, the power supply switching can be controlled. By setting up an anti-accidental contact protection structure and a monitoring interface, users can easily monitor the power supply status and ensure the safety of equipment and the system.

[0025] The enclosure 1 houses a power detection module and a switching control module. The power detection module monitors the voltage, current, and other parameters of the main power supply and the backup power supply in real time. The switching control module controls the switching of power supplies based on the signals from the fault detection module. The display screen 3 and the operation panel 4 provide real-time data display and alarm functions, making it convenient for users to monitor the power status.

[0026] Please see Figure 1-Figure 3 In this embodiment, the protective cover 5 and the front of the protective groove 2 are mutually adapted. The protective cover 5 is made of transparent material. The frame 6 is fixedly connected to the outer side of the protective cover 5. The left side of the frame 6 and the box 1 are rotatably connected by a hinge. The front side of the frame 6 and the box 1 are magnetically connected by a magnetic block 7. The front end of the locking block 8 is locked to the frame 6. The upper and lower sides of the locking block 8 are slidably connected to the inner side of the limiting frame 9. The left end of the pull rod 10 is fixedly connected to the locking block 8. The right end of the pull rod 10 extends through a through hole to the outer side of the limiting frame 9 and is fixedly installed with a handle 101. The rod 10 is slidably connected to the inside of the through hole. The left end of the spring 11 is fixedly connected to the locking block 8, and the right end of the spring 11 is fixedly connected to the inside of the limiting frame 9. After fixing the mounting bracket 12 in a suitable position, the box 1 is placed on the upper end of the support plate 13, so that it is locked with the support plate 13 through the first limiting groove 131, thereby supporting and limiting the box 1. Then, by rotating the knob 151, the lead screw 15 is rotated, so that the fixing plate 14 is lowered until it is locked with the second limiting groove 141, thereby realizing the quick installation and fixing of the box 1, and facilitating its subsequent disassembly and maintenance.

[0027] Please see Figure 1-Figure 5In this embodiment, the support plate 13 is arranged symmetrically from left to right. The front end of the support plate 13 and the lower end of the housing 1 are engaged with each other through a limiting groove 131. The rear end of the support plate 13 is fixedly connected to the mounting bracket 12. The front end of the fixing plate 14 and the upper end of the housing 1 are engaged with each other through a limiting groove 141. The upper and lower ends of the lead screw 15 are rotatably connected to the mounting bracket 12. The lead screw 15 is arranged to pass through the fixing plate 14 from top to bottom. The lead screw 15 and the fixing plate 14 are threaded together. The upper end of the lead screw 15 extends to the upper end of the mounting bracket 12 and a knob 151 is fixedly installed thereon. The guide rod 16 is arranged symmetrically from left to right. The guide rod 16 and the lead screw 15 are parallel to each other. The upper and lower ends of the guide rod 16 are fixedly connected to the mounting bracket 12. The fixing plate 14 and the outer side of the guide rod 16 are slidably connected through the guide hole. When the control panel 4 needs to be operated, the handle 101 is pulled to move the pull rod 10 to move the locking block 8, releasing the fixation of the frame 6, making it easy to open the protective cover 5. Afterwards, by closing the protective cover 5, the magnetic block 7 attracts the frame 6, and the locking block 8 is reset and locked with the frame 6 under the elastic force of the spring 11, realizing the closure and fixation of the protective cover 5. The protective groove 2 and the protective cover 5 protect the display screen 3 and the control panel 4, avoiding accidental button touches that cause abnormal power switching.

[0028] During operation, after fixing the mounting bracket 12 in a suitable position, the housing 1 is placed on the upper end of the support plate 13, and it engages with the support plate 13 through the limiting groove 131, thus supporting and limiting the housing 1. Then, by rotating the knob 151, the lead screw 15 is rotated, causing the fixing plate 14 to descend until it engages with the limiting groove 141, achieving quick installation and fixing of the housing 1, while facilitating its subsequent disassembly and maintenance. When the control panel 4 needs to be operated, the handle 101 is pulled to move the pull rod 10, which moves the locking block 8, releasing the fixing of the frame 6, making it easy to open the protective cover 5. Subsequently, by closing the protective cover 5, the magnetic block 7 attracts the frame 6, and the locking block 8 resets under the elastic force of the spring 11 and engages with the frame 6, thus closing and fixing the protective cover 5. The protective groove 2 and the protective cover 5 protect the display screen 3 and the control panel 4, preventing accidental button touches that could cause abnormal power switching. The switching control module is controlled by... The hard-wired method collects the three-phase (Ua, Ub, Uc) phase voltage and single-phase (Ib) current of the two working incoming lines. The working position nodes of the two incoming line switches can monitor the system parameters of the gas system power supply and the protection start-up switching criteria in real time. The device is equipped with a protection hard plate to select the device to be put into or taken out of the system. The power operation selection switch can flexibly realize the normal switching and switching operation of the gas system power supply. The device monitors the voltage, current and other parameters of the main power supply through the power detection module and judges its operating status in real time. Once a main power supply fault is detected, the device immediately starts the switching control module's switching program to determine whether the switching conditions are met. If the switching conditions are met, the device quickly cuts off the main power supply and connects the backup power supply to achieve seamless switching. Thus, when the main power supply fails, the device can quickly detect the fault signal and switch to the backup power supply in a very short time (usually less than 15 microseconds), thereby ensuring the continuous power supply of the gas system.

[0029] Through the above steps, the display screen 3 and control panel 4 are protected by the protective groove 2 and the protective cover 5 to prevent accidental button touches that could cause abnormal power switching. The power detection module enables real-time monitoring of parameters such as voltage and current of the main power supply and backup power supply. The switching control module can control the power switching based on the signal from the fault detection module. The display screen 3 and operation panel 4 provide real-time data display and alarm functions, making it convenient for users to monitor the power status. This solves the problem that the power supply switching device in the gas system is prone to tripping due to low voltage protection of the high-voltage motor during the switching process, which directly affects the stability of gas and steam supply.
