　　Vacuum Circuit Breaker Editor: The term "vacuum circuit breaker" is derived from its arc-quenching medium and the insulating medium of the contact gap after arc quenching, both being high vacuum. It boasts the advantages of small size, light weight, suitability for frequent operation, and arc quenching without maintenance, making it widely used in distribution networks. The vacuum circuit breaker is an indoor distribution device for 3-10kV, 50Hz three-phase AC systems and is used for electrical equipment protection and control in industrial and mining enterprises, power plants, and substation. It is particularly suitable for applications requiring oil-free operation, minimal maintenance, and frequent operation. The circuit breaker can be configured in central cabinets, double-layer cabinets, and fixed cabinets for controlling and protecting high-voltage electrical equipment.

　　The primary purpose of the controller is to maintain a stable output voltage, and its operating process is very similar to that of a linear controller. That is, the functional blocks, voltage reference, and error amplifier of the controller can be designed to be the same as a linear regulator. The difference lies in that the output of the error amplifier (error voltage) must pass through a voltage/pulse width conversion unit before driving the power tube.

In 1966, vacuum circuit breakers with ratings of 15kV, 26kA, and 31.5kA were developed, marking their entry into high-voltage, large-capacity power systems. By the mid-1980s, the interrupting capacity of vacuum circuit breakers had reached 100kA. Research on vacuum switches began in 1958, and in 1960, Xi'an Jiaotong University and Xi'an Switch Rectifier Factory jointly developed batches of vacuum switches with a rating of 6.7kV and an interrupting capacity of 600A. Subsequently, a 10kV, 1.5kA three-phase vacuum switch was also produced. In 1969, the Huaguang Tube Factory and Xi'an High-Voltage Electrical Equipment Research Institute developed a 10kV, 2kA single-phase rapid vacuum switch. After the 1970s, the development and production of vacuum switches in various specifications were achieved. Vacuum circuit breakers are typically available in multiple voltage classes. The low-voltage models are generally used in explosion-proof electrical applications, such as in coal mines, etc.

　　The switch-mode power supply must be equipped with overcurrent, overheat, and short-circuit protection functions in its design. Therefore, a switch-mode power supply module with comprehensive protection features should be used, and the technical parameters of its protection circuit should match the operating characteristics of the electrical equipment to prevent damage to either. When repairing a switch-mode power supply, first use a multimeter to check for any power components that are short-circuited, such as the power rectifier bridge, switching tube, and high-frequency high-power rectifier tube; and whether the high-power resistors for surge current are burnt out. Then, check for any abnormal resistance at the output voltage terminals; if any of the above components are damaged, they need to be replaced. After completing these steps, if the power supply still does not function normally after connecting the power, proceed to check the Power Factor Correction (PFC) module and the Pulse Width Modulation (PWM) component. Review relevant documentation to familiarize yourself with the functions of each pin on the PFC and PWM modules and the necessary conditions for their normal operation. Poor power load capability is a common fault, often found in older or long-used power supplies, primarily due to aging components, unstable operation of the switching tube, and inadequate cooling. Focus on checking if the voltage regulator diode is overheating and leaking, if the rectifier diode is damaged, or if the high-voltage filter capacitor is damaged. Electrical (electrical, electrical power and equipment) is a general term for the disciplines or engineering fields of electrical power generation, transmission, distribution, use, and the manufacturing of electrical equipment. It is a science that uses electrical energy, electrical equipment, and electrical technology to create, maintain, and improve a confined space and environment, covering the conversion, utilization, and research of electrical energy, including fundamental theories, applied technologies, and facilities and equipment. shxjhs88shhc99
