Heron Popular Science-Go into the power distribution room , learn the secret of protecting the saint with the safety of electricity!
Power distribution room, a familiar site, is also a secret space that most people never get involved in.
Power distribution rooms, it’s rooms for distributing electric energy, play the role of protecting, measuring and distributing electric energy, and are widely found in the electric power systems of buildings such as residential areas, commercial areas, industrial areas, schools and hospitals.
And in the power distribution room, the long-term stationed in a people's （patron saint of electricity safety）- the circuit breaker!
As an integral part of the low-voltage distribution system, circuit breakers are mainly used to protect circuits and equipment, prevent circuit overloads, short circuits and other fault events, and ensure the safe and reliable operation of the power system.
In the entire circuit breaker, the dynamic busbar system is the central role, generally consisting of a set of metal flexible connection strips and block conductive plates, usually made of copper, aluminum or copper-aluminum alloy, with good electrical conductivity and corrosion resistance. Conductive busbar can realize the distribution of electrical energy in the power system to different circuits to ensure the safe operation of the power system, which is also the cornerstone to ensure that thousands of households can safely use electricity.
Today, Heron takes you into the distribution room to study the welding secrets of the frame circuit breaker system in the （patron saint of electricity safety）!
Taking the copper-based dynamic busbar system as an example, usually, the welding processes to be realized in the copper-based dynamic busbar system are mainly contact sheet and silver point welding, welding of the two ends of the soft connection cured into a hard junction, welding of one end of the soft connection to the contact sheet, and welding of the other end of the soft connection to the conductive busbar.Product welding technology considerations are generally focused on: silver point location accuracy and brazing rate, the soft connection itself size accuracy, soft connection and other parts of the welding brazing rate and location accuracy, the depth of the mother row slot weld penetration and solder fullness, the requirements of the conductive mother row and soft connection after the completion of the welding heat-affected zone is small, the welded joints to meet the requirements of tension, resistivity and conductive temperature rise is small. These welding equipment current control accuracy and stability, discharge occupancy rate, pressure control accuracy, the rigidity of the pressurization mechanism and follow-through, tooling repeat positioning accuracy, etc. have comprehensive requirements, one cannot be missing.
Heron specializes in resistance welding technology for over 30 years, and has continued to specialize in the welding process of dynamic busbar system, successfully developed a series of customized welding machines and complete production line solutions for dynamic busbar system products.
Over 30 years of dedicated R&D and the persistent pursuit of welding quality, enabled Heron to pass the market’s test and become the long-term choice of many leading companies in the low-voltage electrical industry!
In the future, Heron is willing to work with customers at worldwide to protect low-voltage electrical products with reliable welding quality and guard the life safety of every user!
