Description

Technical Field

[0001] The present invention relates to the field of electrical safety technology, and in particular to an electrical safety monitoring device and method for an integrated power distribution device. Background Art

[0002] Electrical safety monitoring equipment primarily involves real-time monitoring and management of power distribution systems to ensure safe operation. These devices and methods include, but are not limited to, intelligent power devices, electrical fire monitoring detectors, and network communication connections between the field layer and the main control layer via Ethernet switches.

[0003] Intelligent power devices are designed for TT and TN systems below 0.4 kV. They feature single- and three-phase AC power measurement, four-quadrant energy metering, harmonic analysis, remote signaling input and output, and RS485 or GPRS wireless communication. They monitor fire hazard parameters such as residual current and conductor temperature in distribution circuits, and provide intelligent preventive monitoring and system insulation degradation prediction. They are widely used in various control systems and energy management systems. Electrical fire monitoring detectors monitor residual current and temperature and issue alarms based on these parameters. When the input signal reaches the alarm setting, an audible and visual alarm sounds. The device's indicator lights and buttons provide an intuitive user interface, allowing users to easily set addresses and parameters, as well as perform mute, self-test, and reset operations. Network Communication: Analysis of integrated monitoring and management systems for high and low voltage distribution equipment in intelligent buildings shows that an Ethernet switch in the middle layer enables network communication between field devices and the host computer, improving the system's real-time performance, compatibility, and scalability. This connection method makes data exchange and communication protocol conversion more efficient, while allowing connection and sharing of data information with other systems.

[0004] In summary, the electrical safety monitoring equipment and methods for integrated power distribution devices ensure the safe and stable operation of the power system by real-time monitoring and management of key parameters of the power distribution system, such as current, voltage, temperature, etc., and by preventing potential safety risks in an intelligent manner.

[0005] Based on current analysis, the most common structure of a power monitoring system primarily consists of a field control subsystem. This subsystem's basic components include a programmable logic controller (PLC), protection units, remote I / O units, sensors, protection devices, and actuators. These devices enable the collection of various information from the power system and the execution of relevant control commands, enabling online monitoring and real-time control of operating equipment within the system. Sensors collect various field signals, such as digital, analog, and switching signals, and after processing, transmit the information to the master control terminal via cables, optical cables, or integrated communication networks. The protection unit responds to power line faults or tripping, while the PLC is the key link in initiating control operations through the control program, enabling remote adjustment and control of field control objects. The information processing and control subsystem, or the information processing and control subsystem within a power monitoring system, primarily collects various information through the main control terminal, including status information, data, and video signals transmitted from the communication transmission subsystem. This data is then analyzed by a computer and, after processing, reflected in the human-machine interface subsystem, providing status displays, such as alarms or lighting, to relevant personnel. Manual intervention and control are also possible to meet operational needs. The main control layer, located in a central control room or workshop, is typically equipped with high-performance, high-reliability computers, UPS (uninterruptible power supply), printers, and alarm systems. Power monitoring software is installed on the main control computer. Through its human-machine interface and various management functions, real-time monitoring of the entire power distribution system is possible.

[0006] For example, the application number 201922159964.1 discloses a highly safe power distribution device, including a power distribution cabinet, wherein a plurality of electrical components are fixedly mounted on the rear wall of the inner cavity of the power distribution cabinet, a transmission device is provided on the upper right portion of the power distribution cabinet, a heat dissipation device is provided on the upper middle portion of the power distribution cabinet, a protective device is provided on the upper left portion of the power distribution cabinet, and an inspection door is movably connected to the front left portion of the power distribution cabinet via a hinge. The highly safe power distribution device described in this utility model can dissipate heat from the inner cavity of the power distribution cabinet by providing a transmission device and a heat dissipation device, thereby increasing the service life of the power distribution cabinet, and also preventing abnormal conditions of the power distribution cabinet due to high temperature and energy loss due to cooling. By providing a protective device, the leakage condition inside the power distribution cabinet can be monitored in real time, and people can be reminded of leakage in the power distribution cabinet through a buzzer and an indicator light, thereby increasing the safety factor of the power distribution cabinet when in use.

[0007] However, current electrical safety monitoring equipment cannot automatically switch between main power, reserve power, or shutdown modes. The power switching mechanism is complex and costly. The detection equipment wiring on the distribution cabinet door is easily damaged and used abnormally. The monitoring equipment has a short service life, the cooling equipment is not cost-effective, and the overall level of intelligence is low. Summary of the Invention

[0020] A method for using an electrical safety monitoring device of an integrated power distribution device comprises the following steps:

[0021] S1. The three-position power switching mechanism implements the power switching function. When the first electromagnetic push rod is energized and pushed forward, the first pull block drives the power-on slide A, power-on slide B, power-on slide C, and power-on slide D to slide along the insulating slide rod toward the right vertical plate. The power-on slide D contacts the second limit ring and reaches the limit position. The main power contact on the power-on slide A contacts the main power incoming line contact A, the energy storage power contact separates from the energy storage power incoming line contact A, and the load contact contacts the load contact A. The same rules apply to other corresponding contacts. At this time, the main power supply is supplied.

[0022] S2. When the first electromagnetic push rod loses power and is pulled back by the spring force, the second electromagnetic push rod is energized and pushed forward, and the second pull block stops after contacting the limit block; at this time, the main power contact on the energized slide A is separated from the main power supply line contact A, the energy storage power contact is separated from the energy storage power supply line contact A, and the load contact is in contact with the load contact A. The rules for other corresponding contacts are the same; the machine enters the stop position;

[0023] S3. When the second electromagnetic push rod loses power and is pulled back by the spring force, the first electromagnetic push rod loses power and is pulled back by the spring force, and the energized slide A contacts the first limit ring and stops; the main power contact on the energized slide A separates from the main power inlet contact A, the energy storage power contact contacts the energy storage power inlet contact A, and the load contact contacts the load contact A. The rules for other corresponding contacts remain the same; at this time, the energy storage power supply is supplied;

[0024] S4, the temperature sensor regularly measures the temperature inside the power distribution cabinet, and the data is fed back to the temperature controller, which is compared with the temperature value set in the temperature controller. When the temperature is higher than the set temperature, the copper tube refrigeration fan is activated to automatically cool down the temperature;

[0025] S5, the humidity sensor measures the humidity in the power distribution cabinet, and the data is fed back to the humidity controller, which compares the humidity with the humidity value set in the humidity controller. When the humidity is higher than the set humidity, the dehumidifier is activated to perform automatic dehumidification;

[0026] S6. When the smoke level in the power distribution cabinet is higher than the set value of the smoke alarm, the smoke alarm automatically alarms and transmits the information to the central controller for remote information transmission;

[0027] S7. After the temperature controller, humidity controller, and central controller are initialized and set, daily internal data is remotely transmitted to the terminal. During manual inspection, the normal operation of the device controller can be directly checked through the perspective window and explosion-proof glass without opening the device.

[0028] S8. When the main door or auxiliary door is opened without permission, the door magnetic detector receives a signal, feeds it back to the central controller, and outputs an alarm signal; if an abnormality occurs within the monitoring range of the internal camera or external camera, the signal is fed back to the central controller, and an alarm signal is output;

[0029] S9. When the measured value of the incoming line transformer or the load line transformer exceeds a set value, or the difference between the two exceeds a set value, output an alarm signal;

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. By setting up a three-position power switching mechanism, it can automatically switch between the main power supply, reserve power supply or shutdown mode. This not only ensures that the power distribution device can continue to work in the event of an abnormal power outage, but also provides a shutdown position, thereby improving the versatility of the power distribution device.

[0032] 2. By setting trapezoidal grooves, semicircular guide pillars, arc guide surfaces, and guide slopes, the smoothness of power switching can be effectively improved, with a simple structure and high cost performance;

[0033] 3. By setting up two sets of electromagnetic push rods to realize the action of three sets of switching power supply positions, the structure is simple and the action is precise, which improves the practicality and working stability of the three-position power supply switching mechanism;

[0034] 4. By setting up an integrated embedded detection mechanism, the safety monitoring equipment is centrally fixed inside the power distribution device, and a window is set on the external door. This solves the problem of damage to the detection equipment circuit installed on the power distribution cabinet door and abnormal use during the opening and closing process of the power distribution cabinet door, effectively extending the service life of the monitoring equipment;

[0035] 5. By installing a copper tube cooling fan, the cooling effect is improved compared to conventional fans, the equipment operating cost and manufacturing cost are reduced compared to air conditioners, and the overall cost performance of the distribution device is improved.

[0036] 6. By setting up a multi-source mutual inductance interpolation mechanism, not only can the voltage and current of the main power supply and the load power supply be measured, but also the residual current data can be calculated through interpolation operation, thereby improving the intelligence level of the detection equipment;
