Smart power protection device supplier

1、 Overview

The AISD300 series three-phase intelligent safety distribution device is an intelligent safety distribution solution developed by Ankerui for low-voltage distribution scenarios. It is designed to solve electrical safety problems caused by low voltage systems such as electric shock risk, line aging, short circuit faults, and leakage hazards.

This device can be widely used in various low-voltage power consumption scenarios such as schools, gas stations, medical institutions (hospitals/sanatoriums/rehabilitation centers), nursing homes (nursing homes), commercial service places (hotels/shopping malls/shops), enterprises and institutions, residential buildings, and tourist attractions. Through full time electrical parameter monitoring and intelligent protection strategies, it builds a multi-level safety protection system for terminal electrical equipment, achieving the dual goals of ensuring power supply continuity and eliminating electrical accident risks.

2、 Analysis of Campus Scene Adaptability

2.1 Requirements for Teaching Buildings and Laboratories

pain point:Precision instruments are sensitive to voltage fluctuations and pose a high risk of unauthorized use of electricity.

Solution:The power continuity design of AISD300-60K can ensure the continuous operation of experimental equipment in the event of single-phase grounding faults, while limiting leakage current and avoiding medical accidents or data damage caused by equipment leakage.

2.2 Student Dormitory Requirements

pain point:Frequent unauthorized use of electrical appliances, high risk of electric shock and fire.

Solution:The device uses dynamic leakage current monitoring and human electric shock protection to accurately identify and warn of illegal electricity use behavior, while ensuring that accidental contact does not harm people. Combined with remote monitoring function, administrators can locate hidden danger points in real time and quickly dispose of them.

2.3 Canteen and Kitchen Requirements

pain point:Damp environments can easily lead to insulation aging, and the combination of open flames and electrical risks.

Solution:The IP30 protection level and moisture-proof design of AISD300-60K are suitable for harsh environments. The single-phase grounding spark free technology prevents electric arcs from causing fires. At the same time, energy consumption analysis is used to optimize the power consumption strategy of high-power equipment such as ovens and rice steamers.

3、 Core technological advantage: Directly addressing the pain points of campus electricity usage

3.1 Electricity does not ignite, leak, or harm people

Single phase grounded spark free technology:When a single-phase grounding fault occurs on the load side, the device limits the leakage current to within 10mA through current limiting technology to avoid arc sparks and eliminate electrical fire hazards from the root. This feature is particularly suitable for areas with high concentrations of flammable materials such as school laboratories and canteens.

Dynamic leakage current monitoring:Real time monitoring of line leakage current, immediate alarm when exceeding the threshold, and setting whether to cut off the power supply, balancing safety and power supply continuity. For example, when high-power appliances are used illegally in student dormitories, the system can accurately warn without interrupting the power supply, avoiding affecting normal life.

Human electric shock protection:When the human body accidentally touches a single live wire, the current is limited to below 5mA (far below the 30mA safety threshold), ensuring that even if an electric shock occurs, there is no harm. This function is crucial for preventing students from accidentally touching exposed wires and getting electrocuted in humid environments.

3.2 Rapid response to faults and power supply continuity

Short circuit arc extinguishing protection:By adopting intelligent current limiting technology, short-circuit current can be cut off in microseconds, with a response speed more than 10 times faster than traditional circuit breakers, preventing overheating of the circuit and causing fires.

Single phase grounding without power interruption:When a single-phase grounding fault occurs on the load side, the device only alarms and does not cut off the power supply to ensure the continuous operation of the equipment. The output voltage and current fluctuations are ≤ 4%, avoiding the shutdown of teaching equipment or loss of laboratory data caused by unexpected power outages.

3.3 Intelligent monitoring and remote control

Real time electrical parameter measurement:By using high-precision sensors to monitor parameters such as current, voltage, power, electrical energy, temperature, and insulation resistance, and displaying them intuitively on the touch screen, it supports historical data query (storing 20 event records).

Multi dimensional alarm mechanism:In case of overload, overvoltage, undervoltage, insulation fault or internal overheating, the device will give an audible and visual alarm immediately, and push it to the cloud platform through RS485 or wireless communication (4G/LoRa optional) to support remote monitoring of mobile APP and WeChat official account. For example, administrators can view the electricity load of areas such as classrooms and libraries in real-time and adjust their electricity usage strategies in a timely manner.

5、 Campus Smart and Safe Electricity Solution

The safety electricity monitoring and early warning system uses Internet of Things technology to continuously track and statistically analyze the main factors that cause electrical fires (wire temperature, current, voltage, and leakage current), and discover safety hazards in electrical circuits and equipment in real time (such as abnormal cable temperature, short circuit, overload, overvoltage, undervoltage, and leakage), effectively preventing the occurrence of electrical fires.

Campus, as a densely populated and complex public place with complex electricity usage scenarios, has a direct impact on the safety of teachers and students' lives and property. The traditional electricity management method has problems such as blind spots in monitoring, lagging response, and energy waste. It is urgent to achieve precise monitoring, real-time warning, and efficient management through intelligent means.
