Hot-pluggable power supply monitoring device

Abstract

The invention discloses a hot-pluggable power supply monitoring device to solve the problem that an existing power supply detection sensor cannot be hot-plugged from a power supply system. The hot-pluggable power supply monitoring device comprises a base and a detection module which are connected through insertion. The detection module is internally provided with a sensor, and the base is providedwith a line inlet and a line outlet which are connected with a to-be-measured power supply system and electrical equipment respectively. The detection module is inserted into the base, firstly current of the power supply system passes through the detection module and is detected by the sensor, then the base supplies power to the electrical equipment, and when the detection module is pulled out from the base, the current of the power supply system supplies power to the electrical equipment through the base. When the system is not out of power, a sensor monitoring module can be replaced.

Description

technical field [0001] The invention relates to the field of power monitoring, in particular to a hot-swappable power monitoring device. Background technique [0002] High-voltage DC power supply for communication, also known as HVDC, is a new type of DC uninterrupted power supply system. The high voltage mentioned here is compared with the traditional -48V DC communication power supply. Required occasions, such as data centers, customer service centers, etc. [0003] The HVDC system is mainly composed of AC power distribution unit, rectifier module, storage battery, DC power distribution unit, battery management unit, insulation monitoring device and monitoring module. Among them, the monitoring module is the "brain" and "eyes" of the whole system, which is responsible for the monitoring and processing of the real-time operation of each unit; the insulation monitoring device can monitor the insulation status of the DC bus and the output shunt to the earth in real time, En...

AI Technical Summary

Problems solved by technology

Although there are different types of Hall sensors and leakage current sensors on the market, they are all used alone. Once the device is damaged, the entire HVDC system must be powered off to replace it. The two can be modularized and hot-swapped. Pulled out did not appear

[0005] In addition, the existing monitoring modules and insulation monitoring devices are all connected by wires in the HVDC system, which requires high wiring technology and large space requirements
