AI Technical Summary

Technical Problem

Existing three-dimensional test chambers cannot simulate high-pressure environments for testing electronic and electrical products, and cannot evaluate their explosion-proof performance and flame-retardant performance.

Method used

An explosive atmosphere test chamber was designed, including a chamber body, a cover, a gas connection head, a circuit flange, and a cable connection structure. By adjusting the air pressure and temperature, a high-altitude environment is simulated. Liquefied n-hexane or propane is mixed with air to conduct a fuel ignition test and observe whether the product explodes and the flame spreads under high pressure.

Benefits of technology

It can evaluate the explosion-proof and flame-blocking performance of electronic and electrical products under simulated high-pressure environments, providing a more comprehensive evaluation method.

Abstract

The application discloses an explosion atmosphere test box and a simulation test method thereof, which comprises the following steps: step 11, determining the working temperature of a product to be tested, setting the current temperature of the product to be tested as the working temperature, installing the product to be tested in the explosion atmosphere test box, and sealing the explosion atmosphere test box; step 12, a step for simulating a first height environment test; the first height environment is a height environment 2000 meters higher than the working height of the product to be tested; step 13, a step for simulating a second height environment test; the second height environment is a height environment 2000 meters higher than the field elevation. The simulation test method of the explosion atmosphere test box provided by the application can cyclically observe whether the product to be tested will explode and whether the explosion will spread to the outside of the explosion atmosphere test box, so as to evaluate the ability of the explosion atmosphere test box to block the flame and explosion occurring in the inside of the explosion atmosphere test box.
