Remote monitoring system for grounding device and equipotential bonding fault

Abstract

The invention discloses a remote grounding device and equipotential connection fault monitoring system. The monitoring system comprises at least one monitoring terminal used for monitoring the grounding device and grounding device equipotential connection fault, field warning devices and a remote monitoring device, the field warning devices and the remote monitoring device are connected with the monitoring terminals through communication, and the remote monitoring device is further connected with the field warning devices. Each monitoring terminal comprises a shell and further comprises a power module, a logic controller, a power generator, a switching circuit and a parameter collecting device, all of which are arranged in the shell, wherein the switching circuit is connected with at least one monitoring object through a protection circuit, the parameter collecting device is used for collecting the current value and the voltage value of the monitoring object and sending the collected current value and the collected voltage value to the logic controller, and the logic controller is used for receiving the current value and the voltage value sent by the parameter collecting device to obtain a resistance value, judging the fault state of the monitoring object according to the resistance value and transmitting a monitoring signal and a fault signal to the field warning devices and the remote monitoring device.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a grounding device and a remote monitoring system for equipotential connection faults. Background technique [0002] Grounding devices and equipotential bonding are devices that can dissipate overvoltage and overcurrent and provide a standard zero potential for electronic and electrical equipment. If the grounding device and the equipotential connection fail, it will cause the failure of the lightning protection device, the damage of personnel and equipment caused by the insulation damage of the electrical equipment shell, the electrostatic accident in the flammable and explosive place, and the neutral point failure of the power system and electrical equipment. And electronic digital equipment damage and misuse, etc. [0003] The current patents on grounding devices and equipotential bonding monitoring often focus on the improvement of monitoring methods, and try their best to improve the ...

Problems solved by technology

If the grounding device and the equipotential connection fail, it will cause the failure of the lightning protection device, the damage of personnel and equipment caused by the insulation damage of the electrical equipment shell, the electrostatic accident in the flammable and explosive place, and the neutral point failure of the power system and electrical equipment. and electronic digital equipment damage and misuse, etc.

[0003] The current patents on grounding devices and equipotential bonding monitoring often focus on the improvement of monitoring methods, and try their best to improve the stability and accuracy of monitoring. There is no good monitoring method for the faults of the grounding device and equipotential bonding itself; The monitoring of devices and equipotential connections is often done manually, and most of the grounding devices and equipotential connections are hidden, which makes manual monitoring often very inconvenient. In addition to the special environment of special buildings, manual live operations are easily caused by human negligence. The occurrence of dangerous situations; in addition, because the monitoring of grounding devices and equipotential connections is usually done every six months or once a year, the monitoring of grounding resistance and transition resistance cannot reflect the status of grounding devices and equipotential connections in real time. Very high probability of failure
