Embodiment Construction
[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and examples, but the embodiments of the present invention are not limited thereto.
[0018] The main idea of the present invention is that the detection module is arranged in the shielding cover at the top of the valve tower. If a fire occurs, based on the characteristics of the natural and rapid rise of the hot air flow, the gas temperature sensor in the detection module at the top can detect the temperature. Changes, the smoke sensor can detect whether there is smoke, and it can be detected in the early stage of the fire, which is convenient for the operation and maintenance personnel to deal with in advance, improves the timeliness and reliability of the fire warning of the valve tower, and also ensures the operation of the valve tower. safety.

The present invention relates to a high-voltage direct-current power transmission converter valve valve tower with a fire monitoring function. The valve tower comprises at least two valve layers. A shielding case is disposed above a top valve layer. The valve tower further comprises a detection module. The detection module comprises a controller. The detection module further comprises at least onegas temperature sensor and / or at least one smoke sensor. The controller is separately connected to the gas temperature sensor and / or the smoke sensor. The gas temperature sensor and / or the smoke sensor are / is disposed inside the shielding case. The detection module in the present invention is disposed inside the shielding case of the top valve layer, and by means of a natural rising property of ahot air current, the detection module can fast detect a temperature change, so that occurrences of early fire accidents can be fast alarmed, thereby improving valve tower fire alarm realtime performance and reliability.
Description
technical field [0001] The invention relates to a valve tower of a high-voltage direct current transmission converter valve with a fire monitoring function. Background technique [0002] The converter valve is one of the core equipment of HVDC power transmission. Its function is to complete the AC-DC conversion, convert the AC power into DC power in the rectifier station, and convert the DC power into AC power in the inverter station. At present, most of the DC transmission projects that have been put into operation and are under construction are of ±800kV UHV voltage level, and there are a few ±1100kV UHV voltage levels. The interior of the converter valve equipment is composed of a variety of electrical components. It has been working in a harsh operating environment of high voltage and high current for a long time, and is affected by various factors such as component aging and high voltage impact. It may commutate during long-term operation The hidden danger of fire acci...
