Problems solved by technology
[0002] At present, in the application of low-voltage power distribution panels, 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 power equipment, it is impossible to perform line detection on each point. If there is any connection point with insufficient contact, it will generate heat and make the contact worse. Conversely, the poor contact will cause Greater heat will cause equipment damage, power outage accidents, and cause fires, endangering the safety of personnel and property

The invention relates to an on-line fault pre-diagnosis device of a low voltage distribution panel. The on-line fault pre-diagnosis device of the low voltage distribution panel comprises an on-site supervision PC, a communication device, local side inquiry terminals, a station level general control unit, a voltage measuring device, a capacitive measuring device, a lightning arrester measuring device and an environment measuring device. More than two local side inquiry terminals are connected with the communication device, the communication device is connected with the station level general control unit, and the other end of the station level general control unit is connected to the on-site supervision PC. The voltage measuring device, the capacitive measuring device, the lightning arrester measuring device and the environment measuring device are connected to the other end of the on-site supervision PC. The on-line fault pre-diagnosis device of power equipment can effectively prevent a temperature rise fault caused by overload and bad contact of the low voltage power equipment, and reduce damage to electrified subclass loads. The on-line fault pre-diagnosis device is arranged to be used for detecting the condition of old and new voltage equipment and detecting line faults, the communication mode is used for detection, multi-point comparison, remote comparison and data sharing are realized, reliability is high, and cost is low.

technical field [0001] The invention relates to a fault diagnosis method of an online fault prediagnosis device for a low-voltage power distribution panel. Background technique [0002] At present, in the application of low-voltage power distribution panels, there is no special equipment that can monitor the poor contact of connection points and line conditions. Due to the large number of connection points and wide application range of low-voltage power equipment, it is impossible to perform line detection on each point. If there is any connection point with insufficient contact, it will generate heat and make the contact worse. Conversely, the poor contact will cause Greater heat will cause equipment damage, power outages, and fires, endangering the safety of personnel and property. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a diagnostic method of an online fault pre-diagnosis device for power equipment th...
