Low-voltage electrical industry dedicated constant temperature and humidity test box recommended
Low-voltage electrical products are broadly divided into two categories: low-voltage electrical components and low-voltage complete sets of equipment. The test standards for these two types of products stipulate several necessary environmental tests - damp heat test (constant temperature and humidity test chamber). For low-voltage electrical appliances, product safety performance is one of the main evaluation indicators, so it is particularly important to use the relevant national standard to evaluate the damp heat test project. Whether electrical products have the corresponding humidity resistance is also an important guarantee for product safety performance indicators. The moisture resistance test is to evaluate the adaptability of the appliance under the use of wet and hot environment. Because the insulation resistance and electrical strength of the insulation material are reduced with the increase of temperature and humidity, the influence of temperature and humidity in the climatic conditions on the safety work of the electrical insulation structure is considered. Very big. The moisture resistance test uses artificial climatic conditions to evaluate the heat and humidity resistance of the appliance. This artificial climatic condition should have an approximate simulation of natural climatic conditions and an accelerated test. Generally speaking, when the appliance does not consider surface condensation and respiration during use, a constant temperature and humidity test chamber can be selected. Electrical appliances with condensation as the main moisture mechanism or respiration can accelerate the entry of water and gas into the electrical appliances, and high and low temperature alternating heat and humidity test chambers should be adopted.
