Description

Technical Field

[0001] The present invention relates to the technical field of measurement and control devices, and in particular to an intelligent measurement and control device for a high-voltage common box busbar. Background Art

[0002] The intelligent measurement and control device can monitor key parameters such as voltage, current, and temperature of the high-voltage common box bus in real time to ensure the stable operation of the power system; busbar duct is a high-current transmission tool and is widely used in industrial plants, high-rise buildings and other environments. The conductor inside the busbar duct is made of copper and aluminum composite. Its resistivity and safety are better than traditional cable structures. It has irreplaceable advantages in the field of indoor low-voltage transmission. The inspection of busbar duct is mostly completed by manual inspection. Based on certain safety requirements, personnel conduct weekly or monthly inspections of the busbar duct.

[0003] In the prior art, there is a bus duct measurement and control device and bus duct measurement and control system, such as the publication number CN215419735U. The device includes a measurement and control body, which is arranged at the start and end nodes and the variable capacity node of each bus duct. The normally open contact of the measurement and control body is connected to the shunt release of the switch. The measurement and control body is provided with a power supply unit, a temperature measurement unit, a communication unit, a ground voltage detection unit and a main control unit. The power supply unit is connected to the bus duct connector via a power cord, the temperature measurement unit is connected to the bus duct connector via a temperature detection line, the ground voltage detection unit is connected to the bus duct housing and the connection cover of the bus duct via a ground voltage detection line, and the communication unit exchanges information with the host via wireless or wired transmission. By performing ground voltage detection and real-time temperature measurement on the bus duct to meet the safety requirements of electricity use, the monitoring data is accurate and timely, the transmission effect is excellent, and the cost is low.

[0004] In actual use, although the measurement and control device can meet the power safety needs through voltage detection and real-time temperature measurement, it is affected by internal factors of the bus duct.

The pressure release component 5 and the emergency fire extinguishing component 6 cooperate with each other to realize parameter analysis of the real-time monitoring data, so as to facilitate timely triggering of the protection mechanism. When the internal pressure of the high-voltage common box bus duct 1 exceeds the established threshold, the pressure release component 5 is operated in time to release the air pressure inside the high-voltage common box bus duct 1 in time to prevent and reduce the occurrence of faults. In the event of an emergency fire, the emergency fire extinguishing component 6 is used to realize timely control of the fire to avoid a wider range of power failures and ensure the power safety of the high-voltage common box bus, thereby improving the overall operation quality and management level of the equipment.

[0021] Example 2 On the basis of Example 1, in order to realize the connection and installation between the pressure relief assembly 5 and the upper mounting plate 41: the pressure relief assembly 5 includes a mounting cylinder 51, which is fixedly mounted on the central inner wall of the upper mounting plate 41, and the lower end of the mounting cylinder 51 passes through the upper inner wall of the high-voltage common box bus duct 1, and an inner valve seat 52 is fixedly mounted on the inner surface of the mounting cylinder 51, and a solenoid valve 521 is provided on the inner side wall of the lower end of the inner valve seat 52, and a support plate 55 is fixedly mounted on the upper end of the support plate 55, and a conical cover 551 is fixedly mounted on the upper end of the support plate 55, and the conical cover 551 is an umbrella-shaped structure; the inner valve seat 52 is set as a hollow cylindrical structure, and both ends of the inner valve seat 52 are provided with inlet holes 522, and two groups of inlet holes 522 are provided, and the inner surfaces of the two groups of inlet holes 522 are respectively fixedly mounted with a lower sealing ring 523 and an upper sealing ring 524.

[0022] The installation tube 51 passes through the upper installation plate 41 and the top position of the high-voltage common box bus duct 1. The lower sealing ring 523 and the upper sealing ring 524 are added to enhance the sealing of the valve core 53 and the valve stem 531. The conical cover 551 is installed above the release hole 525 to avoid the problem of external dust accumulating and clogging the release hole 525, thereby further improving the safety of busbar electricity use.

[0023] Example 3 On the basis of Example 2, in order to realize the timely release of the internal pressure of the high-voltage common box bus duct 1: a valve core 53 is movably installed on the inner surface of the lower sealing ring 523, and the upper end of the valve core 53 is fixedly connected to the valve stem 531, and the upper outer surface of the valve stem 531 is movably connected to the inner surface of the upper sealing ring 524; the outer surface sliding sleeve of the valve stem 531 is provided with a telescopic elastic wire 54, the lower end of the telescopic elastic wire 54 is fixedly connected to the upper surface of the valve core 53, and the upper end outer surface of the telescopic elastic wire 54 is fixedly connected to the lower surface of the upper sealing ring 524; a release circular hole 525 is opened on the inner wall of the upper end of the inner valve seat 52, and the release circular holes 525 are set in six groups, and the six groups are arranged in a circular array about the longitudinal center axis of the inner valve seat 52.

[0024] When the air pressure monitor detects that the air pressure inside the high-voltage common box bus duct 1 is too high, the fault diagnosis module monitors and evaluates the operating status of the system in real time based on the analysis results of the data processing module. Then the control module issues corresponding control instructions based on the information provided by the data processing module and the fault diagnosis module to trigger the protection mechanism. At this time, the intelligent measurement and control device body 3 controls the solenoid valve 521 to open. At this time, the air pressure inside the high-voltage common box bus duct 1 enters the inner valve seat 52 through the lower end opening of the inner valve seat 52. The valve core 53 is pushed by the air pressure to drive the telescopic elastic wire 54 to move upward, and the valve core 53 is separated from the inlet hole 522. The air pressure inside the high-voltage common box bus duct 1 enters the inner cavity of the inner valve seat 52. At this time, the telescopic elastic wire 54 is pushed upward by the air pressure. The valve core 53 is separated from the inlet hole 522, and the air pressure inside the high-voltage common box bus duct 1 enters the inner cavity of the inner valve seat 52. The elastic wire 54 is compressed by the pushing action of the valve core 53, and the air pressure is finally released through multiple groups of release circular holes 525 arranged in an array, ensuring that the internal air pressure of the high-voltage common box bus duct 1 is stabilized, thereby achieving the power safety of the high-voltage common box busbar; when the air pressure monitor again monitors that the internal air pressure of the high-voltage common box bus duct 1 has reached stability, the solenoid valve 521 is controlled to close, and then the valve core 53 is merged with the inlet hole 522 under the elastic recovery force of the telescopic elastic wire 54, thereby achieving the sealing of the high-voltage common box bus duct 1, further solving the problem that the existing measurement and control device of the high-voltage common box busbar cannot play a safety protection role while monitoring, and can realize both monitoring and protection functions, thereby achieving the power safety of the high-voltage common box busbar.

[0025] Example 4 On the basis of embodiment three, in order to achieve timely control when a fire occurs: the emergency fire extinguishing assembly 6 includes a lower flange 61, an upper flange 62 and a sealed storage cover 63. The upper outer surface of the upper flange 62 is threadedly connected to the lower inner wall of the sealed storage cover 63. A storage capsule 64 is installed inside the sealed storage cover 63. The outer surface of the lower flange 61 passes through the inner wall of the upper mounting plate 41 and extends to the interior of the high-voltage common box bus duct 1. The lower surface of the upper flange 62 is fixedly connected to the upper surface of the lower flange 61 by bolts. The inner surface of the lower flange 61 is fixedly installed with a limiting cylinder 611. The inner wall of the lower end of the limiting cylinder 611 is fixedly connected to the upper surface of the lower flange 61. An air inlet 610 is provided, and a movable groove 612 is provided on the inner wall of the lower flange 61. A movable block 613 is slidably installed on the inner surface of the movable groove 612. The movable blocks 613 are arranged in four groups, and the inner surfaces of the four groups of movable blocks 613 are fixedly installed with a conical plate 614, and the upper end of the conical plate 614 is fixedly installed with a ejector pin 615; a guide hole 6141 is provided on the inner wall of the lower end of the conical plate 614, and a flow equalizing hole 6142 is provided on the upper inner wall of the conical plate 614; a curved elastic strip 65 is hingedly installed on the outer surface of the lower side of the conical plate 614, and the other end of the curved elastic strip 65 is fixedly connected to the lower inner wall of the limiting cylinder 611.

[0026] When a fault occurs and causes a major fire accident, once a fire occurs in the high-voltage common box bus duct 1, in order to avoid the expansion and spread of the fault range, multiple sets of emergency fire extinguishing components 6 are added to realize the diffusion of fire extinguishing gas, and the pressure is released through the pressure release component 5. At this time, if the internal pressure of the high-voltage common box bus duct 1 is not released in time, the internal temperature of the high-voltage common box bus duct 1 continues to rise, causing the high-voltage common box bus duct 1 to expand due to heat, and there is a high possibility of explosion or fire risk. When this happens, the emergency fire extinguishing component 6 is activated to release inert gas, thereby blocking the surrounding oxygen and assisting in fire extinguishing. The pressure release component 5 and the emergency fire extinguishing component 6 cooperate with each other to ensure a more stable power safety of the bus duct. Specifically: when the internal pressure of the high-voltage common box bus duct 1 exceeds the threshold value, the internal air pressure brings a certain impact to the conical plate 614, at this time the conical plate 614 moves upward due to the impact force from the bottom, and the curved elastic strip 65 is stretched and deformed by the force from above, at this time the conical plate 614 maintains a stable limit in the movement of the limit cylinder 611 through the movable groove 612, and then the conical plate 614 continues to move upward to drive the ejector pin 615 to pierce the storage capsule 64, so that the HFC-227ea gas filled in the storage capsule 64 is released, and the fire extinguishing gas escapes through the equalizing hole 6142 and the guide hole 6141, blocking the surrounding air and extinguishing the fire urgently, avoiding the situation where the staff fail to arrive at the fault location in time, resulting in the spread of fire and the expansion of the fault area, further solving the problem that the existing measurement and control device of the high-voltage common box busbar cannot play a safety protection role while monitoring.

[0027] Example 5 Based on Example 4, the intelligent measurement and control device body 3 also includes an information acquisition module, a signal transmission module, a data processing module, a fault diagnosis module and a control module. The information acquisition module includes a temperature sensor, a humidity sensor, an air pressure monitor and a current monitor. The temperature sensor, humidity sensor, air pressure monitor and current monitor are all arranged on the inner side of the high-voltage common box bus duct 1; the information acquisition module is responsible for collecting various physical quantities and converting them into processable electrical signals or digital signals; the signal transmission module is used to transmit the data collected by the information acquisition module to the data processing module via wired or wireless means; the data processing module is used to receive data from the signal transmission module and perform decoding, storage, analysis and processing; the fault diagnosis module monitors and evaluates the operating status of the system in real time based on the analysis results of the data processing module; the control module is used to issue corresponding control instructions according to the information provided by the data processing module and the fault diagnosis module, trigger the protection mechanism, and adjust the working status or environmental parameters of the equipment.

[0028] Temperature sensor: used to measure the ambient temperature inside the high-voltage common box bus duct 1; humidity sensor: used to monitor the humidity level of the environment; air pressure monitor: used to measure the air pressure inside the high-voltage common box bus duct 1, facilitating the timely release of internal air pressure to prevent the bus from being in a high-voltage operating state; current monitor: monitors the magnitude and changes of the internal current of the high-voltage common box bus duct 1, helping to promptly detect high-voltage shared bus circuit faults or perform power load management; these sensors can comprehensively cover key parameters such as temperature, humidity, air pressure and current, providing the system with rich environmental information and equipment status data.

[0029] In actual use, first, the staff installs the intelligent measurement and control device body 3 on the outside of the high-voltage common box bus duct 1 through the installation base plate 2, ensuring that it is installed in a position that can effectively monitor the busbar operation status and is easy to maintain. Then, multiple sets of sensors are installed inside the high-voltage common box bus duct 1 to monitor the internal operation environment of the high-voltage common box bus duct 1 in real time. When the air pressure monitor detects that the air pressure inside the high-voltage common box bus duct 1 is too high, the fault diagnosis module monitors and evaluates the system operation status in real time based on the analysis results of the data processing module. Then the control module The data processing module and the fault diagnosis module provide information, issue corresponding control instructions, and trigger the protection mechanism. At this time, the intelligent measurement and control device body 3 controls the solenoid valve 521 to open. At this time, the air pressure inside the high-pressure common box bus duct 1 enters the inner valve seat 52 through the lower end opening of the inner valve seat 52. The valve core 53 is pushed by the air pressure to drive the telescopic elastic wire 54 to move upward. The valve core 53 is separated from the introduction hole 522. The air pressure inside the high-pressure common box bus duct 1 enters the inner cavity of the inner valve seat 52. At this time, the telescopic elastic wire 54 is compressed by the top push of the valve core 53. Finally, the air pressure is released. The release holes 525 arranged in multiple groups are released to ensure that the internal air pressure of the high-voltage common box bus duct 1 is stable. In addition, when a major fire accident occurs due to a fault, once a fire disaster occurs in the high-voltage common box bus duct 1, the alarm 32 will first sound an alarm to warn the staff to rush to the scene quickly, and transmit the signal to the data processing module through the signal transmission module. The internal pressure of the high-voltage common box bus duct 1 exceeds the threshold, and the internal air pressure brings a certain impact to the conical plate 614. At this time, the conical plate 614 moves upward under the impact of the bottom, and the curved elastic bar 65 is affected by the upper force. The conical plate 614 is stretched and deformed, and at this time, the conical plate 614 maintains a stable limit in the movement of the limit cylinder 611 through the movable groove 612. Then the conical plate 614 continues to move upward to drive the ejector pin 615 to pierce the storage capsule 64, so that the HFC-227ea gas filled in the storage capsule 64 is released, and the fire extinguishing gas escapes through the equalizing hole 6142 and the guide hole 6141. The release of the inert gas blocks the oxygen around the fire, and emergency fire extinguishing is carried out at the location where the fire occurs, so as to avoid the staff failing to arrive at the fault location in time, causing the fire to spread and the fault area to expand.
