Abstract

The invention is suitable for the technical field of industrial safety, and provides a fault processing method and system for a nuclear power plant, and the method comprises the steps: monitoring the state of a guided wave radar liquid level meter; when the state of the guided wave radar liquid level meter is fault, controlling the output current of the guided wave radar liquid level meter to be within a first range, and when the output current of the guided wave radar liquid level meter is within the first range, enabling the guided wave radar liquid level meter to trigger a control system connected with the guided wave radar liquid level meter to detect that the guided wave radar liquid level meter breaks down; by means of the method and device, the problem that when the guided wave radar liquid level meter breaks down, the guided wave radar liquid level meter cannot send out an alarm message in time, and consequently equipment abnormal action occurs in an associated unit can be solved.

Description

technical field [0001] The application belongs to the technical field of industrial safety, and in particular relates to a fault handling method and system applied to nuclear power plants. Background technique [0002] Guided wave radar level gauge is a liquid level measuring instrument in the chemical industry. The guided wave radar level gauge is a radar level gauge based on the principle of time domain reflectometry (TDR). The electromagnetic pulse of the radar level gauge propagates along the steel cable or probe at the speed of light. On the surface of the medium, part of the pulse of the radar level gauge is reflected to form an echo and returns to the pulse transmitting device along the same path. The distance between the transmitting device and the surface of the measured medium is proportional to the propagation time of the pulse. bit height. [0003] However, when the guided wave radar level gauge fails, for example, it cannot accurately measure the level of the ...
