Cable branch box grounding wire introduction

The conductor connectors in the cable branch box are crimped, which is easy to install and flexible in and out. There can be 6 to 8 branch in and out lines in use, which can realize multi-channel power transmission in the community, providing technical guarantee for penetrating into the load center, shortening the power supply radius, and reducing line loss. At the same time, the cable branch box can be equipped with power indicator, fault indicator, silicone rubber fully insulated insertion arrester, mechanical programmable lock, grounding switch, etc. to ensure the safety of operation and maintenance management. In conjunction with the cable network ring network power supply, SF6 and other ring network load switches can be configured to meet the requirements of local power outage maintenance without affecting the operation of the main network, realize regional power outage maintenance, and reduce the scope of power outage. At the same time, the ring network cable branch box can realize ring network power supply, laying the foundation for the future adjustment of the 10kV line network structure.

my country launches new power transformer, substations can also be built in buildings

As the construction land resources in big cities are becoming increasingly saturated, the research on "indoor, miniaturized and oil-free" substations is of great significance for achieving the coordinated development of substation construction and economic, social and ecological environment. Recently, Shenzhen Aodian High Voltage Electric Co., Ltd. released an innovative product - 220kV evaporative cooling power transformer. As the key to promoting the implementation of the "embedded attached substation" project, this new power transformer will realize the construction of substations in high-density urban central areas.

Discussion on the Insulation Coordination Principle and Verification of Low Voltage Complete Switchgear

Abstract: The insulation coordination problem is an important issue related to the safety of electrical equipment products, and has always received attention from all parties. Insulation coordination is applied in high-voltage electrical products. In my country's electrical products, accidents caused by insulation systems account for 50%-60%. In addition, the concept of insulation coordination has only been formally introduced in low-voltage complete switchgear and control equipment in the past two years. Therefore, it is a relatively important issue to correctly handle and solve the insulation coordination problem in products, and sufficient attention should be given.

Shandong Province's first UHV substation expansion project successfully delivered power

People's Daily Online, Jinan, November 11th. In the early morning of the 11th, with the successful impact of the newly expanded 1000 kV transformer, the expansion project of the first UHV substation in Shandong Province, the Quancheng 1000 kV substation, was successfully powered on. It is reported that the Quancheng 1000 kV substation is the hub substation of the province's ultra-high voltage power grid and an important clean energy channel for the national air pollution prevention and control plan. As the receiving substation of the Ximeng-Shandong UHV AC project, the station has delivered 38.76 billion kWh of clean energy from other provinces to Shandong since it was put into operation in 2016 to October 31, 2019. During the peak period of electricity load in winter and summer, the clean energy from other provinces delivered by the station effectively made up for the gap in Shandong's electricity load and alleviated the tense situation of electricity consumption.

The role of sensors in IoT embedded system design

Many people scratch their heads when it comes to designing effective embedded IoT systems. Sensors are a crucial yet often overlooked aspect in IoT embedded system design. Finding the right sensor for your design is not easy. However, it is the difference between an average system and a top-notch one. It is indeed challenging with the selection and integration of smart sensors. In this article, you will learn about the types of sensors, benefits, challenges, and future trends for your Industrial IoT strategy.
