The Institute of Electrical Engineering and Technology establishes a mash-up fusion communication system
The "Research and Application of Key Technologies for High-Performance Power Line Carrier-Based Distribution and Communication Networks Based on High-Speed ​​Power Line Carriers" was identified by the Yunnan Science and Technology Awards Office. The experts identified the project as the power carrier communication, power carrier channel noise model, and noise reduction. Other aspects are innovative and the main technologies have reached the international advanced level.
In the course of project research, the Institute of Electrical Engineering and Technology established the first domestic distribution and integration intelligent information and communication system at Haoming Power Company, which realized the unified collection, transmission and application of distribution network operation and marketing information. The system covers 16km 10kV lines and 13 low voltage platforms, and the overall network communication rate reaches 12~78Mbps. It can transmit line fault location, online line monitoring, negative control terminals, distribution terminal, concentrator, video surveillance and other information. And applications. The system has also been applied to other county companies.
The system is based on 200M broadband power line communication network research and development, breaking the key technology of power line communication. The so-called power line communication refers to the signal is loaded on the power line transmission, and then the signal is extracted and applied through a modem. The in-depth development of power line carrier communication channels and research on de-noising algorithms, and improvement and improvement of carrier communication test methods and platforms are important prerequisites for the construction of a carrier-integrated converged communication system. For this reason, the Institute of Electric Power has conducted in-depth studies in five areas. One is the development of power line carrier communication channels and de-noising algorithms. The second is to carry out the simulation test research on the power line carrier communication modulation method, and analyze the error rate of different modulation technologies under different communication rates. The third is to carry out research on reducing interference factors that affect high-speed data transmission in power line carrier communications. The fourth is to build a carrier communication test platform. After the successful construction of the platform, it has completed the test analysis and evaluation of the performance of the 18 factory concentrators, collectors and power meter carrier communication. The fifth is the use of the INTEGRATED INTELLIGENT INTELLIGENT COMMUNICATION SYSTEM developed by the Institute of Electrical Engineering. On the one hand, important information such as 10kV circuit breakers, load switches, transformers, and table data on the Taiwan area can be efficiently transmitted to the substation or the nearest fiber-optic connection in real time. In order to provide the most stable and safest standard data communication for various intelligent devices of 10kV medium voltage distribution network, on the other hand, it can greatly improve the efficiency of meter reading and provide remote power management for power supply enterprises. Two-way network communication platform, so as to easily achieve long-distance electricity pre-paid, automatic power-off and anti-stealing features.
In the course of the project's research, the Institute of Electric Power applied for 9 patents for invention, obtained 2 authorizations, registered 2 software copyrights, participated in the preparation of 2 national standards, and published 11 papers, including 1 EI.
Branch Pipe, mean pipe fittings tee or tee fittings, tees and the like. It used mainly to change the direction of flow, with a branch in the main conduit to the Office. Can diameter size classification. General carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum, plastic, argon Ge Lek, pvc and other materials produced.
Casting Branch Pipe is a three hole, namely an inlet and two outlet; or two inlets, a kind of chemical pipe outlet, there are T-shaped and Y-shaped, with equal diameter nozzle, orifice diameter pipe also, for three identical or different line Survey Office. The main role tee is to change the direction of flow.

Divided by the diameter size
1. Tee takeover ends are the same size;
2. Same size - Reducing tee competent to take over, and over size is smaller than the executive branch pipe over size.
Divided by technology
1. hydroforming
Tee hydroforming is compensated by the axial expansion of the metal material of a branch pipe forming process. The process is the use of special hydraulic machine, the injection of the liquid and the inner diameter equal to the three-way tube, side cylinder synchronous movement of the extruded tube by two horizontal hydraulic presses, tube after extrusion by the smaller size, the inner tube the volume of liquid with the smaller tube and pressure rise, when it reaches the three-way manifold pressure required for the expansion, the metal material in the dual role of the cylinder and the inner tube side fluid pressure and flow along the mold cavity bulge manifold.
Tee hydroforming process can be a shape, high production efficiency; competent and shoulder tee wall thickness were increased.
Due to the larger seamless tee hydroforming process equipment required tonnage currently mainly for the manufacture of standard wall thickness less than DN400 tee. Its application for the molding material is relatively low work hardening tendency of low-carbon steel, low alloy steel, stainless steel, including some non-ferrous materials, such as copper, aluminum, and titanium.
2. thermoforming
Thermoforming tee tee is greater than the diameter of the tube, flattening about to tee diameter size,
Stretching branch site to open a hole; tube by heating, into the forming die, and a tensile load manifold die within a tube; tube is radially compressed under pressure, radial compression during the metal flow direction and forming the manifold branch pipe in a stretched punch. The whole process is by radial compression and stretching process tube manifold portion is shaped. Tee hydraulic bulging difference is that hot tee branch pipe metal tube is carried out by radial motion compensation, it is also known as radial compensation process.
Because after pressing tee by heating the material forming the equipment needed to reduce the tonnage. Hot links to wider adaptability of materials suitable for low-carbon steel, alloy steel, stainless steel material; especially large diameter and wall thickness bias tee, often use this forming process.
