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

Embodiment 1

[0053] like figure 1 , figure 2 , image 3 , Figure 4 Shown is Embodiment 1 of the present invention, in which a hot-swappable power supply monitoring device is provided, including a base 1 and a detection module 2, the detection module 2 is plugged and combined with the base 1, and the detection module 2 is set There are sensors, and the base 1 is provided with inlets 1-13 and outlets 1-21, which are respectively connected to the power system under test and electrical equipment; when the detection module 2 is inserted into the base 1, the current of the power system first passes through the detection module 2. After being detected by the sensor, power is supplied to the electrical equipment through the base 1. When the detection module 2 is pulled out from the base 1, the current of the power system directly supplies power to the electrical equipment through the base 1.

[0054] Through the above configuration, it is possible to replace the detection module 2 when the po...

Embodiment 2

[0082]The difference from Embodiment 1 is that the sensor in this embodiment only includes miniature Hall sensors 2-3, and only detects electrical energy, but the hot-swappable power monitoring device in this embodiment is not only suitable for DC power supply systems , It is also suitable for AC power supply system and has a wider range of adaptation.

[0083] Other structures of the hot-swappable power supply monitoring device in this embodiment are the same as those in Embodiment 1, and will not be described again here.

Abstract

The invention discloses a hot-swappable power supply monitoring device, which is used to solve the technical problem that the existing power supply detection sensor cannot be hot-swapped from a power supply system. The hot-swappable power supply monitoring device includes a base and a detection module, the detection module is plugged and combined with the base, the detection module is provided with a sensor, and the base is provided with a wire inlet and a wire outlet , respectively connected to the power system under test and the electrical equipment; when the detection module is inserted into the base, the current of the power system first passes through the detection module, is detected by the sensor, and then passes through the base to the When the detection module is pulled out from the base, the current of the power supply system directly supplies power to the electrical equipment through the base. The invention realizes the replacement of the sensor monitoring module under the condition that the system is powered off.

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...
