1. Electrical fire monitoring system installation electrical fire monitoring according to the project material list, carefully verify the components and cables required for project implementation to ensure that they are accurate, and prepare the tools and accessories required for site construction, and use standard electrical installation tools and detection instruments

At that time, UPS seemed to be a high-tech object that only large companies could afford, but with the continuous development of technology and the continuous reduction of cost, UPS began to gradually enter the ordinary family. Nowadays, the medium-sized supermarket at the entrance of the community, even the students' dormitory, are using UPS. ...

UPS classification a inverter working mode: online, backup, online interactive ■ inverter output waveform: sine wave, square wave (step wave). According to power capacity: small power, medium power, high power ■ battery backup time: long delay

The internal UPS system has phase to phase short circuit due to aging of lines. The fault current causes a fire in the UPS power supply panel, which further leads to AC series DC, and breakdown of the varistor in the measurement and control device, which leads to multi-point grounding of the DC system, and finally leads to the loss of background monitoring system and remote communication

Concept: electrical fire generally refers to the heat energy released due to the failure of electrical lines, electrical equipment, appliances and power supply and distribution equipment; such as high temperature, electric arc, electric spark and non fault released energy; such as the hot surface of electric heating appliances, in the presence of combustion conditions

Ups will be used in many situations, but we don't know about ups. It mainly provides standby continuous power. It is used in many scenarios. Many times, it is because it is not good. So today, we will explain some relevant knowledge of UPS uninterruptible power supply

What is ups? Many people may not know this product very well. But when we talk about some common applications of UPS, we can understand immediately. For example, what should we do if there is a power failure during operation? We did not see the power failure in the operating room of the hospital that day. What is the purpose of this situation
