Description

Technical Field

[0001] This invention relates to the field of electrical equipment condition monitoring technology, and in particular to an improved device for remotely monitoring the condition of electrical equipment. Background Technology

[0002] Electrical equipment is a general term for various devices and supporting components that rely on electrical energy to achieve operation, control, transmission and energy conversion. It is widely used in production, construction, power and daily life scenarios, covering the entire process of power generation, transformation, transmission, distribution and consumption. It includes transformers, switch cabinets, cables, motors, lighting fixtures, control instruments, protection devices, etc. This type of equipment can complete the generation, transmission and distribution of electrical energy, power drive, signal monitoring and safety protection. It is the basic hardware for the stable operation of the power system, the automation of various mechanical operations and daily power supply, ensuring power safety and rational use of energy.

[0003] Electrical equipment status monitoring uses sensor acquisition, data monitoring, and real-time analysis to continuously track changes in the operating parameters and conditions of various electrical equipment. It captures key indicators such as temperature, current, voltage, insulation performance, and vibration in real time, dynamically grasps the operating status of equipment, and promptly identifies potential hazards such as overload, aging, abnormal heating, and line faults. Relying on real-time data comparison and anomaly warning, it breaks away from the traditional periodic maintenance model, accurately judges the health status of equipment, identifies potential faults in advance, ensures the safe and stable operation of electrical equipment, and reduces downtime risks and maintenance costs.

[0004] In the power production process of a power plant, the stable operation of various auxiliary motors such as fans and pumps directly determines the overall operational safety and continuous operation of the generator set. At present, the status monitoring of the standby motor power circuit generally relies on manual periodic inspections. Maintenance personnel need to travel back and forth between various power distribution rooms and local control cabinets, and rely on visual inspection of the mechanical position of circuit breakers to judge the power supply status. Frequent opening and closing of cabinets can easily cause electric shock hazards. This monitoring mode has a delayed response, and sudden faults such as power tripping are difficult to detect in a timely manner. The fault detection delay is long, and the equipment tripping status is only displayed locally and cannot be uploaded to the DCS and other centralized monitoring systems of the entire plant in real time, which makes it impossible for centralized control operators to quickly grasp the actual operating status of the circuit.

[0005] Therefore, it is necessary to provide an improved device for remotely monitoring the status of electrical equipment to solve the above-mentioned technical problems. Summary of the Invention

[0022] Please refer to Figure 1 and Figure 2 The miniature voltage acquisition module includes a voltage sensing unit, a signal isolation unit, a terminal block unit, and an insulation protection unit. The voltage sensing unit is used to collect the main power supply voltage signal on the primary side of the motor in real time.

[0025] Please refer to Figure 1 and Figure 5 The local status indication module includes a normal indication unit, a power failure alarm unit, a status reset unit, and a local display unit; The normal indicator unit indicates that the power supply voltage is in a normal state. When a high-level signal is received, the normal indicator light illuminates, providing a direct and intuitive display of normal power supply for easy on-site verification. The power failure alarm unit indicates a power failure fault state. When a low-level signal is received, the alarm indicator light illuminates, providing a quick and local prompt of power tripping for easy on-site location. The status reset unit enables manual reset and confirmation of the local status. The reset button resets the latched signal, supporting on-site manual confirmation and reset, improving operational flexibility. The local display unit integrates status display and operation interface, combining indication and reset functions into a unified panel for a compact, intuitive, and clear structure, facilitating on-site inspection and monitoring.

[0026] The working principle of the improved remote monitoring device for electrical equipment status provided by this invention is as follows: This design utilizes a miniature voltage acquisition module, an intelligent signal processing module, a remote signal upload module, and a local status indication module to collaboratively monitor the motor's power status. The miniature voltage acquisition module collects the power supply voltage on the primary side contactor of the motor in real time via a voltage sensing unit. This voltage is converted into an isolated low-voltage signal by a signal isolation unit and stably output by a terminal block unit. An insulation protection unit ensures safe operation. The intelligent signal processing module receives the acquired signal, filters and amplifies it to eliminate interference, and compares it with a preset value set by a voltage comparison unit. A logic latch unit outputs a stable power-on or power-off switching signal. A power management unit provides continuous power throughout the entire process. With stable power supply, the remote signal upload module isolates interference through an opto-isolation unit and uploads standard status signals to the DCS system via a communication interface unit. The signal drive unit ensures reliable long-distance transmission, and the disconnection detection unit monitors the integrity of the transmission loop in real time. Meanwhile, the local status indication module drives the normal indication unit or power failure alarm unit to achieve local visual display based on the processing results. The status reset unit supports manual reset on site, and the local display unit integrates display and operation functions. The entire device completes the entire process of acquisition, processing, uploading, and indication with pure hardware circuitry, converting the power supply voltage status into a standard switch quantity that the DCS can recognize, achieving second-level real-time monitoring and remote centralized alarm without the need for manual on-site cabinet inspection.

[0034] Compared with related technologies, the improved remote monitoring device for electrical equipment status provided by the present invention has the following advantages: When this device is in operation, the mounting assembly 1 is pre-fixed on the mounting rail inside the switch cabinet.
