The important role of hydrogen sensors installed in power plants


The battery compartment is a compartment where batteries are stored. According to the working principle of lead-acid battery, the positive active material of lead-acid battery is lead dioxide. The negative active material is lead sponge. The electrolyte is a dilute sulfuric acid solution. When charged to 70% to 80%, the positive electrode begins to produce oxygen. When the charge is almost 90% complete, the negative electrode begins to produce hydrogen gas. Hydrogen is a flammable and explosive Class A substance. The explosion limit in air is 4.1% to 74.1%, and the ignition temperature is around 450℃. Therefore, the hydrogen concentration in the charging chamber can easily reach the explosion limit, and it will explode when it encounters a fire source. To pay attention to the environmental monitoring of battery rooms and power plants, we can use hydrogen sensors for monitoring.

Monitoring action using hydrogen sensor:

Hydrogen has a wide range of explosion limits. When mixed with chlorine, it can explode when exposed to heat or sunlight. It will explode immediately if mixed with fluorine. Its ignition energy is very small, only 0.019mJ. A tiny open flame. Such as acrylic, really good and other clothes due to friction caused by static sparks, can cause explosions. In addition, a violent impact can also cause an explosion. Therefore, power plants and substations equipped with lead-acid battery packs should install hydrogen detectors. Always monitor the hydrogen concentration in the battery compartment.

Fixed gas detector, stable performance, sensitive and reliable. With high-precision liquid crystal display, explosion-proof housing, diffusion type or pump suction type. The H2 detector has the characteristics of flexible use and simple operation. The H2 detector is used in various gas leakage places, such as: city gas, petroleum, chemical, pharmaceutical, steel, special industrial plants and other fields. The explosion-proof level of the H2 detector is CT6.
