In the operation of power enterprises, the use of electrical equipment has become increasingly common. As power supply companies strive to meet higher development standards, the quality requirements for electrical operating equipment continue to rise. Therefore, to ensure the normal operation of electrical equipment, regular maintenance and care are essential. This article first analyzes the necessity of routine inspection and maintenance of electrical equipment, then discusses the main aspects of daily maintenance, and finally introduces practical methods that facilitate the daily upkeep of electrical equipment.

IntroductionIn urban and industrial power distribution systems, ensuring stable and continuous power supply is a major challenge. Equipment failure or power interruption can lead to significant losses. Choosing a reliable ring main unit is essential to improve system safety and reduce downtime.Why R

IntroductionIn medium voltage power distribution systems, safety and reliability are critical. Many industrial projects face challenges such as unstable performance, difficult maintenance, and limited space. Choosing the right switchgear is essential to ensure stable operation and long service life.

The KYN28-12  is an indoor, metal-clad, withdrawable medium voltage switchgear rated for 3.6kV to 12kV (24kV optional), widely used in power plants, substations, industrial facilities, and renewable energy projects. It features a "Five Anti" safety interlock system to prevent human operational errors, a modular withdrawable trolley compatible with VS1, VD4, and VEP circuit breakers, robust aluminum-zinc coated steel construction, four independent compartments (breaker, busbar, cable, and low-voltage sections), and optional internal arc classification up to 31.5kA/1s. With rated current up to 3150A and short-circuit breaking capacity up to 40kA, the KYN28-12 complies with IEC 62271-200 standards and remains the industry benchmark for reliable medium voltage secondary distribution.
