HXGN-12 Indoor AC High-Voltage Metal-Enclosed Ring Main Unit
The HXGN-12 fixed-type high-voltage ring main unit (hereinafter referred to as the ring main unit) is suitable for power distribution systems in industrial and mining enterprises, residential communities, high-rise buildings, schools, parks, and other similar applications. It serves as an indoor, 50 Hz, three-phase ring-network power supply unit and terminal distribution equipment with a rated voltage of 10 kV. The unit is capable of making and breaking rated load currents and no-load transformer currents, as well as making and breaking capacitive currents from overhead lines, cable lines, or capacitor banks over specified distances. The load switch–fuse combination switchgear can also interrupt short-circuit currents, making it ideal for use in power systems as protective, distribution, and control equipment; it is also suitable for installation in packaged substations.
KYN28A-12 AC Metal-Clad Withdrawable Switchgear
The KYN28A-12 armored, withdrawable, AC metal-enclosed switchgear (hereinafter referred to as the switchgear) is designed for use in 3–12 kV three-phase AC systems at 50 Hz, with rated currents ranging from 630 to 3,150 A, in single-bus and single-bus sectionalized configurations, for the reception and distribution of electrical energy.
GGD Low-Voltage Complete Switchgear
The GGD-type AC low-voltage distribution cabinet is suitable for power distribution systems in power plants, substations, industrial and mining enterprises, and other power-consuming facilities, operating at 50 Hz, with a rated working voltage of 380 V and a rated working current of up to 3,150 A. It is used for the conversion, distribution, and control of electrical energy in power, lighting, and distribution equipment.
GGJ Low-Voltage Reactive Power Compensation Device
The GGJ low-voltage reactive power compensation device is suitable for AC 50 Hz, 380 V low-voltage distribution networks in industrial and mining enterprises, construction sites, real estate developments, residential communities, and other similar applications. It can improve the power factor of the distribution system, reduce losses in power transformers and transmission lines, enhance power supply efficiency, and optimize the power supply environment.
Variable-potential multi-terminal measurement is primarily used to determine whether the location of partial discharge lies between the winding and ground or within the winding itself. This is because, under these two wiring configurations, the UU14 two-phase support with one phase remaining unchanged persists. However, the induced voltage multiplication factor Et is significantly lower in the latter case than in the former; therefore, if the partial-discharge data before and after the test are essentially consistent, it is more likely that the partial discharge originates at the end of the winding. Conversely, if there is a substantial difference between the pre- and post-test partial-discharge data, it is more probable that the partial discharge occurs inside the winding—particularly between turns, between饼s, or between layers.
State Grid Takes the Lead in Deploying Electric Vehicle Charging Stations in Beijing
Following its lead over oil companies in setting industry standards, power utilities have once again taken the initiative in Beijing’s race to establish a comprehensive network of electric-vehicle charging stations. Yesterday, a representative from State Grid Beijing Electric Power Company (hereinafter referred to as “Beijing Electric Power”) disclosed that the company will soon commence construction of EV charging stations across the city and is on track to complete Beijing’s first such station next month.
Accelerated Grid Development: Smartization Becomes the Trend in Low-Voltage Electrical Apparatus
After more than 50 years of development, the low-voltage electrical appliance industry has now established a relatively complete industrial system, with products that are widely used and boast enormous market potential. Based on the demand for distribution equipment required to support newly added power-generation facilities during the Eleventh Five-Year Plan period, as well as the need for replacement and maintenance of existing power equipment, it is estimated that the total demand for products such as universal circuit breakers, molded-case circuit breakers, miniature circuit breakers, AC contactors, thermal relays, and residual-current circuit breakers will exceed 200 million units.
