Common Questions and Answers -Let electricity no longer harm humanity- Introduction In previous comments, we collected readers’ frequently asked questions about IoT leakage protection circuit breakers. Today, we will address them to help alleviate your concerns: 01 Does the anti-electric shock function of the IoT circuit breaker require a network connection to operate? Will it … Read more
The mini circuit breaker, abbreviated as MCB, is a widely used circuit breaker product with a vast range of applications. Its main function is to provide protection for electrical distribution devices at building electrical terminals. It is suitable for overload and short-circuit protection of circuits with an AC rated voltage of 230/400V at a frequency … Read more
Leakage Circuit Breaker / The working principle of the leakage circuit breaker is When functioning normally, there is no leakage current passing through the leakage protector except for the working current in the circuit. At this time, the current flowing through the zero-sequence current transformer (detection transformer) is equal in magnitude and opposite in direction, … Read more
Recently, the “Non-Contact Optical Sensor-Based Hydraulic Disc Spring Mechanism Circuit Breaker Mechanical Characteristic Monitoring Technology” project, jointly developed by Xikai Electric, a subsidiary of China West Electric, and the Southern Power Grid Ultra High Voltage Transmission Company, successfully passed the industry certification organized by the China Machinery Industry Federation. According to the expert committee’s review, … Read more
Environment: Applicable to Multi-9 C60 circuit breakers (UL489 and UL1077) The attached document provides the power loss (watts loss) and voltage drop per pole at the rated current (nominal current) of the circuit breaker. For example, at a rated current of 1A, the expected power loss per pole for a 1A circuit breaker is 2.3 … Read more
Using <span>OkHttp</span>, <span>HttpClient</span>, or <span>RestTemplate</span> to initiate <span>HTTP</span> requests directly in a <span>SpringBoot</span> project is cumbersome and inconvenient for unified management. Therefore, I recommend a lightweight HTTP client framework suitable for <span>SpringBoot</span> projects: <span>retrofit-spring-boot-starter</span>, which is very simple and convenient to use while providing many enhanced features. The project has currently been updated to version … Read more
In distributed system development, recurring cross-cutting concerns (such as logging, monitoring, security, etc.) often become a major source of code redundancy. This article shares five core techniques for using Spring AOP in a Spring Boot distributed architecture, based on real project experience, to help you improve code quality and development efficiency. 1. Distributed Log Tracking: … Read more
