Description
本考案は火力発電所ボイラ火炎検出器電源分配最適化装置に関し、燃焼室セキュリティ監視技術分野に関する。 This invention relates to a power distribution optimization device for a thermal power plant boiler flame detector, and to the field of combustion chamber security monitoring technology.
火炎検出器は燃焼室セキュリティ監視システムのフロントエンドプロセッサであり、それが提供する信号が正確かどうかは、燃焼室セキュリティ監視システムの正常な稼働に決定的な役割を果たしている。ボイラの火炎検出器は燃焼室内の燃焼状況を判断する重要な指標であり、ボイラが正常に点火燃焼しているかどうか及び火炎の強弱に重要な根拠を提供し、燃焼室内の燃焼状況をタイムリーかつ確実に検出することができる。そのため、火炎検出器の正常な稼働が特に重要になっている。 The flame detector is the front-end processor of the combustion chamber security monitoring system, and the accuracy of the signal it provides plays a crucial role in the normal operation of the combustion chamber security monitoring system. The boiler flame detector is an important indicator for judging the combustion situation in the combustion chamber, providing important evidence for whether the boiler is igniting and burning normally and the strength of the flame, and can detect the combustion situation in the combustion chamber in a timely and reliable manner. Therefore, the normal operation of the flame detector is particularly important.
現在、ボイラ火炎検出器電源分配盤の電源は、ボイラ電気室工場用電源（１Ｋ）とボイラ電気室工場用電源（２１Ｋ）の２つの電源から単独で電力を供給し、現場電源盤内の電源切替装置を経て現地火炎検出器に出力されている。各炭層の四隅の火炎検出器は、現場電源分配盤内の電源切替装置から２４Ｖ電源を出力して電力を供給する。電源分配盤が電気を失ったり、盤内の電源切り替え装置が故障したりして破損すると、すべての炭層の火炎検出器が電気を失ったり、ボイラＭＦＴを誘発したりするため、改善が必要である。 Currently, the power supply for the boiler flame detector power distribution panel is supplied independently from two power sources: the boiler electrical room factory power supply (1K) and the boiler electrical room factory power supply (21K), which are output to the on-site flame detector via the power switching device in the on-site power supply panel. The flame detectors at the four corners of each coal seam are supplied with power by outputting 24V power from the power switching device in the on-site power distribution panel. If the power distribution panel loses power or the power switching device in the panel breaks down and is damaged, all of the coal seam flame detectors will lose power and induce boiler MFT, so improvements are needed.
上述の従来技術における欠点を克服するために、本考案は火炎検出器の電源喪失のリスクを効果的に低減し、電源の安定、信頼性の高い稼働を保証することができる火力発電所ボイラ火炎検出器電源分配最適化装置を提案した。 To overcome the shortcomings of the conventional technology mentioned above, the present invention proposes a thermal power plant boiler flame detector power distribution optimization device that can effectively reduce the risk of power loss for the flame detector and ensure stable and reliable operation of the power supply.
上記目的を達成するために、本考案は以下の技術案を採用し、
火力発電所ボイラ火炎検出器電源分配最適化装置であって、各炭層に設置された第１火炎検出器電源、第２火炎検出器電源、第３火炎検出器電源、第４火炎検出器電源を含み、周辺機器の第１工場用電源、第２工場用電源、第３工場用電源、第４工場用電源、第１冗長ダイオード、第２冗長ダイオードをさらに含み、第１工場用電源と第２工場用電源は、それぞれ２つの電源変換装置に接続された後、第１冗長ダイオードに接続され、且つ第１冗長ダイオードはそれぞれ第１火炎検出器電源と第４火炎検出器電源に接続され、第３工場用電源と第４工場用電源は、それぞれ２つの電源変換装置に接続された後、第２冗長ダイオードに接続され、且つ第２冗長ダイオードは、それぞれ第２火炎検出器電源と第３火炎検出器電源に接続されている。
In order to achieve the above objectives, the present invention adopts the following technical solutions:

By installing the redundant diode, the conventional power supply switching device avoids the phenomenon of temporary power loss existing due to the mechanical characteristics during power supply switching, and the redundant diode is more reliable and responds more quickly, and achieves redundancy for the two-way power supply, realizing bumpless switching of the power supply.
