Do you recognize the primary system diagram of the KYN28-12 switchgear?

A complete high-voltage system consists of the following components:   1. Incoming switchgear (receives power from the high-voltage system, i.e., the source of the high-voltage system) 2. PT switchgear (provides busbar voltage signals for this section of the high-voltage system, enabling ene... Read More

Application of armored high-voltage cabinet（KYN28） power system

“Armored KYN28 Switchgear” is the common name in the power industry for the KYN28A-12 armored removable AC metal-enclosed switchgear. This type of high-voltage switchgear is designed specifically for indoor power distribution systems. The following is a comprehensive description of it... Read More

Installation and application of cable branch boxes in urban construction

With the acceleration of urban construction, the conflict between 10kV line corridor planning and urban development and construction is becoming increasingly severe. To meet the needs of social development and ensure safe, stable, and reliable power supply, cable lines are being implemented in ke... Read More

A wide variety of distribution cabinets

Distribution panels can be categorized in various ways based on different standards, primarily by voltage level, structural features, installation method, and location. 1. By Voltage Level: • Low-voltage distribution panels: Typically refers to distribution panels rated at 1 kV or below, used to ... Read More

Do you know short circuit impedance?

Short-circuit impedance is a critical parameter of electrical equipment such as power transformers and reactors. It characterizes the impedance characteristics of the equipment under short-circuit conditions and is crucial for equipment operation, protection design, and grid stability analysis. C... Read More

Do you know the power supply radius of the transformer?

The power supply radius of a transformer refers to the distance from the transformer to the farthest power-consuming device. It is affected by several factors, including voltage level, cable type, load size, and voltage quality requirements. Generally speaking, the low-voltage power supply radius... Read More

Compensation application of low voltage active filter cabinet in power system

Active power filters are primarily used to dynamically filter harmonics and compensate for reactive power, improving power quality and equipment reliability. They detect and compensate for harmonic currents in real time, making the current injected into the grid closer to a sine wave, thereby red... Read More

SF6 gas insulated ring main unit

GIS (Gas Insulated Switchgear) is a high-voltage switchgear that uses SF₆ gas as the insulating medium. It seals components such as circuit breakers, disconnectors, earthing switches, transformers, lightning arresters, and busbars within a grounded metal casing, achieving compact and reliable pow...

The structure and classification of transformer oil conservator

As the volume of transformer oil expands or decreases with temperature, the oil conservator regulates the oil level, ensuring the transformer tank is always full. Without an oil conservator, fluctuations in the oil level within the tank can have several negative consequences:   First, when ... Read More

Main components of transformer voltage regulation–tansformer tap changer

Transformer tap changer Transformer voltage regulation is to set a tap on a certain winding of the transformer. When the tap is changed, a part of the wire turns is reduced or increased, so that the number of turns of the transformer winding with the tap is reduced or increased, and the number of... Read More

Do you know about the principle and structure of transformer windings?

The winding is the most basic component of the transformer. Together with the core, it is called the power transformer body. It is the circuit part that establishes the magnetic field and transmits electrical energy. The power transformer winding consists of high-voltage winding, low-voltage wind... Read More

The structure and use of transformer core，Which ones do you know?

Single-phase two-column laminated core The core sheets are stacked in an overlapping manner, and the two columns are covered with coils, which are led out by series and parallel connecting lines. The structure is simple and compact, with less process equipment, but the stacking workload is large.... Read More
