(Extremely  early) Intelligent power distribution particle sensing warning system

Environmental Monitoring System-Early Fire Warning System

1. Typical electrical faults

Electrical failures of high and low cabinet electrical switches, cables, etc. may occur due to poor contact, moisture, overload, etc.

2.  Solve industry pain points

After years of careful research, our company has a core patented multifunctional laser particle sensing sensor, which is designed for extremely early electrical fault detection and early warning technology to meet the safe operation of various high and low voltage cabinet distribution systems. At the same time, it uses the Internet of Things technology, wireless transmission 4G or wired 485 communication technology to combine, which is more convenient for networking, online 24-hour platform and APP monitoring, and has the function of dispatching orders to arrive at the scene to solve the problem as soon as possible.

When an electrical fault occurs, the main heating element is the cable and the protective electrical switch joint, the cable polyvinyl chloride (PVC) insulation sheath and the protective electrical insulation sheath (ABS material). The temperature rise produces particles, which, as the name implies, are the particles in the air decomposed when the material is heated. The product uses extremely early laser detection particle technology, mainly monitoring the changes in particle concentration in the protected area, and can be widely used in the monitoring of electrical faults in relatively closed places such as high-voltage distribution cabinets, low-voltage distribution cabinets, transmission switch cabinets, server cabinets, generator cabinets, etc., making up for the traditional temperature rise detection technology, realizing extremely early fault warning of electrical faults, preventing problems before they occur, and innovating the operation and maintenance of the power industry!

2.  Innovation Advantages

1. Detection: The detector obtains gas particles in the air by sampling. The sampling method can be active or passive. The active method is to obtain gas particles by blowing air flow into the air, while the passive method is to obtain gas particles through the natural flow of air. The detector is usually equipped with a filter to remove dust and other impurities in the air to ensure the accuracy of detection.

2. Pyrolysis: The pyrolysis device inside the detector heats the collected gas to a high temperature, causing it to undergo a pyrolysis reaction, further decomposing the gas into smaller molecules or atoms. The purpose of this step is to better identify and detect pyrolyzed gas particles in the gas.

3. Component analysis: The component analyzer inside the detector performs component analysis on the pyrolyzed gas. Through technical means such as spectral analysis, chromatographic analysis or mass spectrometry, determine whether there are flammable or toxic gases in the gas, as well as their concentration.

4. Warning and alarm: Based on the results of the component analysis, the detector determines whether the preset warning or alarm conditions have been met. If the early warning conditions are met, the detector will send out an audible and visual warning signal to indicate that there may be a fire hazard; if the alarm conditions are met, the detector will send out a fire alarm signal and link the fire fighting system to carry out emergency measures such as fire extinguishing.

Advantages of pyrolytic particle detectors: It can detect potential fire hazards early and take corresponding preventive measures. In addition, since it adopts a non-contact detection method, it will not be affected by factors such as ambient temperature, humidity, and air pressure, and has high stability and reliability.

3.  Product functions and parameters

    The main heating elements of electrical faults in high and low voltage distribution cabinets are the particles decomposed by the wires and protective electrical joints when heated, which can detect electrical faults in high and low voltage distribution cabinets at an early stage.

When an electrical fault occurs, the material decomposes into particles and gases when heated. This is the smallest material component in which such particles can exist in a free state. Regardless of the cause of the electrical fault, the early stage is manifested as the heating of the object, the release of particles, gas, and the generation of odor. The main heating elements of electrical faults in high and low voltage distribution cabinets are cables, load switches and protectors. The particles decomposed by heating in the distribution cabinet are mainly smoke particles and gas molecules. Using laser particle sensors, measuring particles can monitor the concentration of particles and gases generated by overheating and decomposition of electrical equipment such as polyvinyl chloride insulated cables, lead-acid batteries, circuit breakers, and load switches, and implement alarms before visual smoke is generated to determine the heating of the insulator, and achieve extremely early monitoring of electrical faults to prevent them before they happen.

6. Linked fire extinguishing plan

Perfluorohexanone fire detection tube fire extinguishing device uses perfluorohexanone as the fire extinguishing agent. Perfluorohexanone is a liquid at room temperature. Since its evaporation heat is only 1/25 of that of water, and its vapor pressure is 25 times that of water, these properties make it easy to vaporize and exist in a gaseous state. It mainly relies on heat absorption to achieve the effect of fire extinguishing. In terms of environmental protection, it is a veritable green and environmentally friendly fire extinguishing agent.

This type of fire extinguishing device uses a flexible and bendable fire detection tube as a fire detection and alarm component. At the same time, this fire detection tube can also serve as a pipeline for conveying and spraying fire extinguishing agents. The flexible fire detection tube can be easily arranged to the nearest point of each potential fire source. Once a fire occurs, the fire detection tube will rupture due to heat and immediately release the fire extinguishing agent to extinguish the fire.
