Heavy-duty Connectors Light Up Modern Cities
The lights are still on, and the night is still early. The bustling and noisy modern metropolis blooms at the moment when the lights come on every night. Whether it is a financial center, a leisure green space, a commercial port or a cultural capital, reliable and intelligent power supply is undoubtedly one of the core foundations for all of this to operate freely.
With the increasing agglomeration effect of modern cities, many early power supply systems are facing the transformation and upgrading of distribution network systems. However, how can these urban power supply bureaus complete the challenge of wiring the distribution network as soon as possible without significantly affecting regional power consumption?
On-site wiring is a complex project. With the popularization of smart grids and the upgrading of old stations, the number of Heavy Duty Connector lines between primary switch cabinets and secondary protection equipment has gradually increased, and the requirements for product quality are also constantly improving. As an investment hotspot in recent years, the DTU three-remote products of the power grid and the distribution terminals of secondary equipment have always had clear technical specifications: that is, the DTU three-remote terminals of heavy duty 12 volt connectors primary and secondary equipment need to be equipped with aviation sockets, and 12v heavy duty connector cables use aviation plugs.
After years of use, traditional round air plugs have exposed more and more problems, including unstable brand quality, insufficient tension, and inability to process on site, which not only reduces the wiring efficiency of DTU, but also brings safety hazards. At the same time, the heavy duty crimp connectors technology designed for harsh industrial environments has gradually entered the field of vision of some power grid companies - this heavy duty waterproof electrical connectors technology with the advantages of pre-installation, pre-wiring, anti-wrong insertion, tougher and stronger is more suitable for this heavy duty connector application of distribution networks.
On the other hand, this air plug-in heavy duty electrical connectors mainly completes voltage loop signal detection, control signal loop detection and current loop signal detection. "The connections required for the first two loop detection functions can be completed by ordinary straight-through products. The key is that the products required for the third loop detection function of the current transformer must have the requirement to prevent open circuit." According to the relevant staff of Veidemyuller, an electrical connection expert, "Because in the power grid system, when the current transformer is in operation, once the secondary circuit is open, the secondary equipment winding will generate a very high induced potential, which may cause personal electric shock injury, equipment insulation breakdown, and CT core strength."
Veidemyuller proposed a connection solution that takes into account both reliability and safety: the first two loop detection applications are solved by common heavy-duty connection products, and the third one provides an innovative heavy-duty open-circuit connector for the CT current loop detection connection. Through the seamless switching of the internal mechanism of the ferrule, the open-circuit connection of the secondary circuit of the current transformer in the power system is perfectly realized.
The innovative heavy-duty open-circuit connector finally brought obvious benefits to this project: waterproof, dustproof and small animal bite-proof, good product quality, high wiring reliability; maintenance-free and on-site adjustment; easy to upgrade in the future, etc.
