Multichannel online detection underwater equipment insulation property system and method thereof

Abstract

The invention discloses a multichannel online detection underwater equipment insulation property system. The system comprises a power supply module, an isolation module, an acquisition module, a processing module, an alarm module, a switch module and equipment to be detected. The power supply module, the isolation module, the acquisition module, the processing module and the alarm module are connected. The switch module is connected to the isolation module, the equipment to be detected and the processing module. The acquisition module detects an electric signal caused by insulation property changes of the equipment to be detected and sends to the processing module. The processing module converts the received electric signal into an insulation resistance value and determines whether the resistance value is less than a threshold. When the insulation resistance value is less than the threshold, an alarm instruction is emitted. When the insulation resistance value is greater than or equal to the threshold, a switch is closed and whether an insulation resistance value of a next channel of equipment is detected is determined. By using the system, an insulating property of the underwater equipment to be detected can be detected in on-line, multi-channel and real-time modes and detection efficiency is high.

Description

technical field [0001] The invention relates to the field of marine equipment detection, in particular to a system and method for multi-channel online detection of underwater equipment insulation. Background technique [0002] For most marine equipment, since the cabin shell is in direct contact with seawater, the insulation between the cabin shell and the internal circuit is extremely important. Once the insulation drops, the internal circuit, the cabin shell, and seawater will form a If the circuit is broken, it is easy to cause electrochemical corrosion of the metal shell, and even cause a short circuit, directly damaging the device. [0003] Therefore, the detection of the insulation of marine equipment is extremely important. There are three main reasons for the decline in insulation: one is equipment leakage, which is mainly caused by unreliable sealing, especially in deep-sea applications; the other is unreliable equipment installation. , the equipment installation p...
