Abstract
Description
Technical Field
[0001] The invention relates to the technical field of water-immersion leakage prevention, and in particular to a device for preventing leakage during water immersion. Background Art
[0002] In many power usage scenarios, flooding often causes leakage accidents, posing a serious threat to personnel safety and equipment. Traditional leakage prevention devices have many limitations when dealing with flooding.
[0003] 1. Water immersion detection Single detection method Most of the previous water intrusion detection devices use sensors with a single principle for water intrusion detection, such as using only simple electrode sensors. This single detection method is easily interfered by environmental factors, such as dirt on the electrode surface, humidity changes, etc., resulting in inaccurate detection results. In complex actual environments, misjudgments may occur, such as misjudging condensed water on the electrode surface as large-area water intrusion, or failing to detect trace water intrusion in a small space.
[0004] Lack of multi-scenario adaptability There are various water immersion scenarios in different power usage environments. For example, there may be large areas of water accumulation in industrial plants, and there may be trace water seepage in the narrow space inside electronic equipment. Traditional water immersion detection devices cannot adapt well to the water immersion detection needs of these different scenarios. The detection sensitivity may not be enough for large-area water immersion, and it may be completely impossible to detect trace water immersion, which cannot fully guarantee the safety of equipment in various water immersion situations.
[0005] 2. Leakage protection Disadvantages of fixed protection parameters Traditional leakage protection devices usually set fixed leakage protection response time and action threshold. However, the actual leakage situation is complex and changeable. The leakage current size and danger level vary greatly under different electrical equipment, different degrees of flooding and different environmental conditions. Fixed protection parameters cannot be adjusted according to the real-time leakage situation, which may lead to untimely protection in some cases and excessive sensitivity and frequent false action in other cases.
[0006] For example, in some high-humidity environments, slight leakage may be a normal phenomenon of moisture on the surface of electrical equipment. If the action threshold of the leakage protection device is set too low, the circuit will be frequently cut off, affecting the normal operation of the equipment. Conversely, if the action threshold is too high in the case of severe water immersion, it will not be possible to protect the safety of personnel and equipment in time.
[0007] 3. Control and alarm Lack of intelligent control strategy Traditional leakage protection devices often use simple control strategies based on a single condition (such as whether water intrusion is detected) when controlling the power on and off. This strategy does not take into account multiple factors such as the degree of water intrusion, the water intrusion scene, and the type of electrical equipment, and cannot achieve accurate power control. For example, for some large industrial equipment that is not very sensitive to water intrusion, it may not be necessary to cut off the power immediately when it is slightly flooded, while traditional devices may cut off the power across the board, affecting production efficiency.
[0008] Single alarm function Existing leakage alarm devices usually can only send out a single type of alarm signal, such as a simple buzzer or a single color flashing light. This single alarm signal cannot effectively convey the severity of flooding and leakage and the type of electrical equipment involved, making it difficult for operators to pay enough attention and not conducive to quickly locating faulty equipment.
[0009] 4. Fault maintenance No self-diagnosis and repair capabilities Traditional leakage protection devices lack self-diagnosis and repair functions. Once a device fails, it can only rely on regular manual inspections to discover the problem. This leads to untimely fault discovery, and the equipment is in an unprotected state during the fault period, increasing the risk of leakage accidents. In addition, manual maintenance costs are high and efficiency is low. For some remote areas or equipment installation locations that are difficult to reach, manual maintenance is even more difficult.
[0010] Therefore, the present invention particularly proposes a device for preventing leakage when immersed in water to solve the above problems. Summary of the invention
