Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0015] A method for logically judging a fire tripping device in a valve hall of a converter station. The fire tripping device makes a logical judgment based on the detection signal of a detector. Ultraviolet detector, the logical judgment method is: when the very early detector of the air inlet detects no abnormality, if at least one valve hall very early detector detects abnormality and at least one valve hall ultraviolet detector detects abnormality, then the fire tripping device operates Tripping: When the very early detector of the air inlet detects abnormality, if at least two valve hall ultraviolet detectors detect abnormality, the fire tripping device will operate to trip.

[0016] Based on the above technical solutions and in conjunction with the accompanying drawings, the following specific implementation is given.

[0017] The valve hall fire tripp...

Abstract

The invention relates to a convertor station valve hall fire tripping device logic judgment method. A fire tripping device performs logic judgment according to detection signals of detectors, wherein the detectors are divided into an air inlet ultra-early-stage detector, intra-valve hall ultra-early-stage detectors and intra-valve hall ultraviolet detectors. The logic judgment method includes the following steps that: when the air inlet ultra-early-stage detector detects no anomalies, and if at least one valve hall ultra-early-stage detector detects anomalies, and at the same time, at least one valve hall ultraviolet detector detects anomalies, the fire tripping device acts and drips; and when the air inlet ultra-early-stage detector detects anomalies, and if at least two valve hall ultraviolet detectors anomalies, the fire tripping device acts and drips.

Description

technical field [0001] The invention relates to a logic judging method for a valve hall fire tripping device of a converter station, belonging to the technical field of microcomputer protection. Background technique [0002] Converter valves are key equipment for DC transmission and are expensive. However, the fire accidents in the valve halls of converter stations in recent years have put forward higher requirements for the implementation of fire protection in valve halls of converter stations. Generally speaking, the length of system downtime caused by fire is related to the degree of equipment damage. If the fire can be detected and suppressed early, the system downtime will be short, otherwise it will be long. After a fire occurs, the existing measures only issue an alarm signal and cannot immediately stop the operation to eliminate the fault. Therefore, the relevant departments have proposed to change the fire and smoke alarm system of the valve hall of the converter st...
