Description

Technical Field

[0001] The present application relates to the technical field of explosion-proof testing, and in particular to a hydrogen-related explosion-proof device and a hydrogen-related explosion-proof system. Background Art

[0002] At present, the inspection and testing of hydrogen fuel cells must involve a hydrogen electromagnetic compatibility laboratory, in which explosion-proof test equipment is crucial to ensure the safety of equipment and operations in the laboratory. The test equipment used in hydrogen-related environments needs to meet explosion-proof requirements, and due to the special nature of electromagnetic compatibility laboratories, it is necessary to meet the requirements of instruments and equipment used near the test pieces as much as possible, especially when using mobile test systems. A series of special requirements need to be considered to adapt the test equipment to the electromagnetic compatibility environment.

[0003] Generally speaking, the electromagnetic compatibility test systems on the market also have the following disadvantages:

[0004] (1) During the electromagnetic compatibility test, the instrument will generally be close to the device under test. Near the hydrogen-related device under test, a single instrument may generate sparks, strong radiation, and high-power electromagnetic waves. If a hydrogen leak occurs, a violent explosion will occur depending on the ignition energy of the combustible gas, posing a threat to personnel and equipment.

[0005] (2) In traditional non-explosion-proof hydrogen-related electromagnetic compatibility laboratories, the test equipment includes electromagnetic compatibility test receivers, signal generators, power amplifiers, etc., which need to be moved close to the device under test during testing. Traditional equipment that uses explosion-proof cabinets usually occupies a large area and is not convenient to move (relatively thick and heavy casing).

[0006] (3) If the EMC laboratory is divided into hydrogen-related and non-hydrogen-related parts, and the relevant instruments are installed far away from the device under test, according to the requirements of the EMC experiment, it will lead to a huge increase in costs and may even be impossible to implement in engineering.

[0007] (4) Heating of equipment and systems may cause increased hydrogen concentration, increasing the risk of explosion. In addition, traditional equipment lacks protective performance, and cables and connectors may generate static electricity and cause sparks in hydrogen environments. To solve these problems, specially designed explosion-proof heat dissipation equipment, explosion-proof cables, and increased sealing are required to ensure the safe operation of the equipment. When designing and operating laboratories, relevant explosion-proof safety standards and regulations must be followed to ensure that the equipment meets explosion-proof requirements to reduce the risk of fire and explosion;

[0008] (5) The general standard traditional explosion-proof hydrogen-related cabinets on the market do not have the ability to provide convenient electromagnetic compatibility testing. Utility Model Content

[0009] The purpose of the embodiments of the present application is to provide a hydrogen-related explosion-proof device and a hydrogen-related explosion-proof system, which can achieve the technical effect of reducing the danger and cost of hydrogen-related tests and improving the convenience of hydrogen-related tests.

[0102] In terms of mobility, the hydrogen-related explosion-proof device provided in the embodiment of the present application can adopt a wheeled design, so that it is relatively easy to move in the laboratory. The alternative of track-based movement can also be implemented in the embodiment of the present application, or other more flexible and lightweight metal and non-metal materials can be introduced to improve the overall mobility; different compact device appearance designs or structural layouts are considered to adapt to laboratories of different sizes and shapes, which may include modular designs, folding structures or more efficient space utilization methods, such as the installation position of the explosion-proof fan can be a top or side modular setting; the internal air source can be replaced by other means to also achieve a micro-positive pressure state without ignition threat.
