How are pyrolysis particles formed?

Enquiry Back

 Pyrolytic particles refer to tiny particles produced by the thermal decomposition of solid or liquid materials at high temperatures. In a fire, the combustion process releases a large amount of heat, which heats the surrounding materials. When the temperature of the material rises to a certain level, the molecules begin to move and vibrate. As the temperature continues to rise, the molecules begin to break and release combustible gases and pyrolysis products, including pyrolytic particles. Electrical failures caused by electrical joints, cable joints, moisture, overload, short circuit, and excessive contact resistance of battery joints inside high and low voltage distribution cabinets lead to power outages, which seriously affect power safety and production and bring immeasurable economic losses. Several reasons such as overload of electrical components or cables and excessive contact resistance are all caused by the heating of conductors, which cause electrical or cable materials to produce a large number of electric particles. Since there are relatively many components and joints inside high and low voltage distribution cabinets, traditional manual inspection methods cannot promptly report problems, and failures caused by temperature rise or moisture are very hidden. High-tech acquisition technology with high accuracy and fast response time must be used. Online services can meet the precise monitoring of various electrical distribution systems.

It has the technology of early detection and early warning of electrical faults, and is designed to meet the safe operation of various high and low voltage cabinet distribution systems. At the same time, it uses the combination of Internet of Things technology, wireless transmission 4G or MONBUS-RS485 communication technology, which is more convenient for networking, online 24-hour platform and APP monitoring, and has the function of dispatching orders, and arrives at the scene to solve the problem as soon as possible. When an electrical fault occurs, the main heating elements are 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 substance is heated. The product adopts very early laser detection particle technology, which mainly monitors the changes in particle concentration in the protected area. It 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., which makes up for the traditional temperature rise detection technology, realizes very early fault warning of electrical faults, and prevents problems before they occur.


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 particle is the smallest material component that 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 visually visible smoke is generated, determine the heating of the insulator, and realize very early monitoring of electrical faults.
