[0002] At present, in the application of low-voltage complete sets of equipment, there is no special equipment that can monitor the poor contact of the connection point and the condition of the line.
Due to the large number of connection points and wide application of low-voltage complete sets of equipment and lines, temperature measurement or line detection cannot be performed on each point. If any connection point has poor contact, it will generate heat and make the contact worse. Conversely, the contact is poor. It will cause more heat, cause equipment damage, power outage accidents, and cause fires, endangering the safety of personnel and property

Embodiment Construction
[0015] Further describe the present invention below in conjunction with accompanying drawing. Such as Figure 1 to Figure 4 The online fault diagnosis device for power equipment shown includes an intelligent power measurement and control instrument, a communication device, and an on-site monitoring host.
[0016] figure 1 Shown is that in embodiment 1, the measuring terminal of one intelligent power measuring and controlling instrument is connected to the voltage measuring point of the bus bar under test; The communication terminal of the intelligent power measuring and controlling instrument is connected with the communication device through the field bus; the communication device is connected with the on-site monitoring host, and the on-site monitoring host processes and displays the data. The synchronous information of voltage sampling is sent by the communication device through the bus, and each ZKP8108-A reads the voltage value and uploads it, and the communication devi...

The present invention relates to a power equipment on-line fault prediagnostic equipment by utilizing voltage comparison mode. Said equipment includes intelligent power measuring control instrument, communication device and field monitoring main machine. Said invention also provides the concrete function of the above-mentioned every portion and their connection mode. It can effectively prevent the temperature-rise fault due to overload and poor contact of low-valtage complete equipment.
Description
technical field [0001] The invention belongs to the field of power supply and distribution, and in particular relates to an online fault prediagnosis device for power equipment that uses a voltage comparison method to diagnose equipment and lines. Background technique [0002] At present, in the application of low-voltage complete sets of equipment, there is no special equipment that can monitor the poor contact of the connection point and the condition of the line. Due to the large number of connection points and wide application of low-voltage complete sets of equipment and lines, temperature measurement or line detection cannot be performed on each point. If any connection point has poor contact, it will generate heat and make the contact worse. Conversely, the contact is poor. It will cause more heat, cause equipment damage, power outage accidents, and fires, endangering the safety of personnel and property. Contents of the invention [0003] The object of the present...
