Power Industry Solutions

Yongxin company has one belt, one road, and the other is the advanced design and production equipment. We are providing high quality and reliable distribution box equipment and electrical engineering line equipment for all the other countries. All the products have passed CCC certification and passed the inspection by the third-party authoritative testing organization.

Yongxin company specializes in R & D, manufacturing and supply of "yxcn" brand and "Quanshang" brand: comprehensive distribution box, cable distribution box, street lamp control box, single-phase three-phase split type energy meter metering box, energy meter counter, transformer, as well as PVC conduit, bolt lifting ring and other power auxiliary materials and hardware.

2016-2020 overseas performance: Ethiopia capital project provides integrated distribution box and distribution box products for State Grid CET company, distribution box and line equipment for China Machinery "CMC" Guyana phase I and phase II, single-phase and three-phase split watt hour meter metering boxes for China Power Construction "PowerChina" South Sudan capital power distribution project, and exports 30000 sets of distribution equipment in total.

Development plan of overseas power distribution equipment:

1st step: the bidding document is obtained, and the Chinese version is translated by the Ministry of Commerce and submitted to the electrical business department;

2nd step: Electrical Engineer and mechanical engineer of electrical business department shall cooperate to interpret technical requirements, design products according to requirements, and form procedure documents and drawings;

Third step: verify the design, trial produce the products, and send them for inspection and certification;

4th step: prepare bidding documents (quotation documents, business documents and technical documents);

5th step: win the bid and sign the cooperation contract;

6th step: material preparation, production, Party A's on-site inspection during production;

7th step: inspection, packaging and transportation of finished products;

8th step: product quality tracking, after-sales service.

 

Figure 1: RS485 Communication Version System

SDH - Synchronous Digital Hierarchy (Unified frame structure digital transmission standard rate and standard optical interface, so that the network management system interworking);

MSTP - Multi-Service Transfer Platform (Based on SDH platform, it can access, process and transmit TDM, ATM and Ethernet services simultaneously, and provide multi-service nodes for unified network management);

OLT - Optical Line Terminal (1. transmit Ethernet data to ONU (optical network unit) in broadcast mode; 2. initiate and control the ranging process and record the ranging information; 3. allocate bandwidth for ONU; that is to control the starting time and sending window size of ONU sending data);

POS - Optical fiber splitter;

ONU - Optical Network Unit (Receive broadcast data sent by OLT);

RS485 - communication interface (Network communication interface);

Figure 1, 2, 3 show three versions of Fiber Acquisition Power Management System. The grid of fiber of all the versions are only access to the Concentrator. The meters used are not fiber meters with meter-used ONU. Fiber meter is not recommended because no-existing product, low cost-effectiveness, and unstable performance (Pre-paid meter are optional). So, these versions all use common meters using RS485 communication or micro power wireless communication. All the signals will be collected and decoded by Concentrator. Then the fibers with ONU, POS, OLT and Main Station will achieve the functions of Metering, Monitoring, Pre-payment, Control of distribution, etc.

Figure 1: RS485 Communication Version System = (Pre-paid meters) x RS485 + (Concentrator + ONU + POS + OLT ) x Fiber + PC (Main station monitoring)

Figure 2: Micro power wireless Version System = (Pre-paid meters) x wireless + (Concentrator + ONU + POS + OLT) x Fiber + PC (Main station monitoring)

Figure 3: Micro power wireless Version System = (Pre-paid meters) x (wireless + RS485) + (Concentrator + ONU + POS + OLT) x Fiber + PC (Main station monitoring)
