Embodiment 1

[0038] Such as figure 1 , figure 2 As shown, this embodiment provides a temperature sensing system for a DC power distribution cabinet for power supply in a high-performance computer room,

[0039] include:

[0040] A number of temperature sensors 100 are mounted on the incoming and outgoing busbars of the circuit breaker in the DC power distribution cabinet, specifically on the busbar closer to the wiring, for collecting temperature data and transmitting the data according to the pre-configured communication address. temperature data;

[0041]The temperature monitoring module 200 is connected to several temperature sensors 100 through the "1-WIRE" bus, and is used to centrally receive the temperature data transmitted by several temperature sensors 100, integrate and form a temperature data set before transmission; in addition, the temperature monitoring module 200 is also used for the setting of upward communication parameters, such as baud rate, parity, etc., and provide...

Embodiment 2

[0050] The difference between this embodiment and the previous embodiments is that since the power supply voltage level loaded in the high-performance computer room DC power distribution cabinet is DC300V, the temperature sensor 100 needs to work or even work in a strong electric environment for a long time; therefore, the temperature sensor 100 The surface is encapsulated with an outer sheath made of high temperature resistant and flame retardant material. The setting of the outer sheath can prevent the temperature sensor 100 from being damaged by the strong electric environment.

[0051] Further, the outer sheath is a heat-shrinkable sleeve. The heat-shrinkable tube facilitates the packaging of the conventional temperature sensor 100 and has low manufacturing cost.

[0052] Such as image 3 As shown, the temperature sensor 100 is limited and fixed on the incoming and outgoing busbars through the insulating clip 110. The insulating clip 110 fixes the temperature sensor 100 ...

Embodiment 3

[0057] The difference between this embodiment and the previous embodiment is that, if Figure 4 As shown, the background server 400 includes an alarm module 410, which is used to classify the temperature data and the temperature data corresponding to the temperature data according to the communication address and the pre-stored communication address mapping table with the same DC power distribution cabinet as a group. The installation location of the temperature sensor, and compare the temperature data with the preset alarm threshold, if it is greater than the preset alarm threshold, an alarm signal is sent, and the communication address mapping table stores the data of the installation location of the temperature sensor 100 corresponding to the communication address , which are uploaded by the system personnel according to the installation situation of the temperature sensor 100 in advance.

[0058] The temperature data is grouped together in the same DC power distribution ca...

Abstract

The invention discloses a temperature sensing system of a DC power distribution cabinet for supplying power to a high-performance computer room. The temperature sensing system comprises a plurality oftemperature sensors, a temperature monitoring module, a serial sever and a background server, wherein the plurality of temperature sensors are surface-mounted onto an incoming line busbar and an outgoing line busbar of a circuit breaker in the DC power distribution cabinet and are used for acquiring temperature data and transmitting the temperature data according to a communication address configured in advance, the temperature monitoring module is connected with the plurality of temperature sensors by a 1-WIRE bus and is used for receiving the temperature data transmitted by the plurality oftemperature sensors in a concentrated way and transmitting the temperature data after integrating to form the temperature data, the serial server is connected with at least one temperature monitoringmodule by a RS485 bus, the background server is used for receiving a data set of the serial server and determining attribute of the temperature data according to a mapping table of the correspondingaddress in the data set during temperature data receiving and a preset communication address. By the temperature sensing system, the temperature change condition of a key point in the DC power distribution cabinet can be fed back in real time and on a large scale, real-time monitoring and accurate positioning of a fault are facilitated, the data real-time performance is good, and the system safetyand cost performance is high.

Description

technical field [0001] The invention relates to the technical field of power distribution management under electrical equipment and electrical engineering, in particular to a temperature sensing system for a DC power distribution cabinet used for power supply in a high-performance computer room. Background technique [0002] In the power distribution system of the high-performance computer room, the DC power distribution cabinet is directly fed to the main engine room, the power distribution density is high, and the operating current of a single cabinet exceeds 3200A. Therefore, it is necessary to install a large number of sensors inside the DC power distribution cabinet to grasp the temperature changes in the position of potential safety hazards in the cabinet in real time, which is necessary for the safe operation of power distribution in high-performance computer rooms; but how to find the key points for monitoring and install sensors correctly , has become the key to ach...
