The chemical industry is a reflection of a country's comprehensive national strength. In recent years, there have been many chemical enterprises with large scale, strong continuity, high safety requirements, and high demands for distribution automation. Therefore, higher requirements have been put forward for power supply continuity, safety, and reliability. In response to the demand characteristics of the chemical industry, Gongneng Electrical has proposed industry-leading solutions. By calculating various parameters of the system, selecting distribution protection devices reasonably, and using a microcomputer protection system for comprehensive monitoring and control, production safety is guaranteed.
With the development of future technology, the integration of energy technology with automation and software technology requires highly reliable and high-performance switchgear. Low voltage switchgear, as an important component of the distribution network, is difficult to expand or renovate in engineering applications due to the wide variety of low-voltage cabinet types on the market and the unique appearance and structural forms of each cabinet manufacturer. For various reasons, State Grid Corporation of China has begun to promote the standardization of low-voltage switchgear. Through standardized design, not only can the overall quality of low-voltage distribution cabinets be improved, but user satisfaction can also be enhanced.
In recent years, China's photovoltaic industry has expanded rapidly. With the attention and policy support of the country, China has become the country with the largest new installed capacity of photovoltaics in the world. The photovoltaic industry has become an energy direction that cannot be ignored. Whether it is large-scale photovoltaic power plants, building photovoltaics, or intelligent microgrids, they can all reduce system losses, reduce costs, and improve system power generation efficiency.
Industrial energy electrical products have been widely used in the electronic product manufacturing industry, providing reliable guarantees for the stable and reliable operation of their power supply and distribution systems. Through analyzing a large number of practical cases, Gongneng Electric has continuously improved its solutions and proposed key measures and improvement directions to prevent electrical accidents in electronic product enterprises. For example, electrical faults, voltage fluctuations, or electrostatic discharge should be treated equally, with a focus on preventing power quality accidents, electrical equipment accidents, and operational accidents. It has established a comprehensive power supply and distribution system management system for customers, supplemented by a scientific and effective power supply and distribution network monitoring system, greatly reducing the probability of electrical accidents and improving the reliability and stable operation of enterprise power supply and distribution systems.
As the global solar industry transitions from traditional 1000V DC to higher-performing 1500V DC system architecture, the demands on safety switches, disconnectors, and isolation terminals have scaled dramatically. High-voltage strings enable longer arrays and reduce cable requirements, yet they present significant electrical safety challenges. The primary threat stems from DC arcing. Unlike AC systems, where the voltage crosses zero twice every cycle (facilitating arc extinction), DC power maintains a continuous, uninterrupted flow. Once a DC electric arc is ignited due to cable damage or component wear, it will not self-extinguish. Left unchecked, these hot plasma channels reach temperatures exceeding 3000°C, risking severe equipment damage and structural fires.
To achieve the safety, durability, and reliability requirements expected of modern utility installations, electrical designers must specify components designed specifically for high-voltage DC protection:
At Zhejiang Igoye Energy Technology, we implement rigorous high-voltage endurance testing on all circuit breakers, surge protectors, and isolation switches. By placing quality controls at every stage of manufacture, we ensure that every unit leaving our Yueqing facility functions reliably in extreme environments, protecting both workers and solar assets.
Access comprehensive technical advice on selecting component suppliers, import compliance, product modifications, and electrical system protection.
A thorough audit must analyze: (1) Technical qualifications, including CE, RoHS, and local utility certifications. (2) Quality assurance tools, such as the use of Statistical Process Control (SPC) and materials tracking. (3) Production and test hardware capability, ensuring the factory has automated test benches to verify trip ranges, isolation gaps, and insulation resistance. For example, ZHEJIANG IGOYE ENERGY manages a 12,000m² factory with 180+ specialized production and test units to ensure uniform performance.
Solar arrays cover large outdoor areas, making them vulnerable to induced lightning surges. These surges create high-energy transient spikes that damage inverters, combiner boxes, and monitoring logic. Installing specialized DC Surge Protective Devices (SPDs) limits the transient voltage to a safe level, protecting expensive system components and minimizing downtime.
AC current naturally crosses a zero-voltage point twice per cycle, helping to extinguish arcs. DC currents do not have this zero-voltage point, meaning arcs must be physically extinguished by stretching and cooling. DC circuit breakers feature deeper arc chutes, magnetic blowouts, and reinforced barriers to safely isolate high-voltage DC circuits.
ATS components monitor source reliability. If the main grid drops or goes out of spec, the ATS quickly switches auxiliary power loads to backup battery systems or diesel generators. This maintains power continuity for critical infrastructure, such as water treatment, petrochemical processing, or hospital systems.
