Description
Technical Field
[0001] This utility model relates to the field of heating tube testing technology, and in particular to a high-temperature heating tube performance testing device. Background Technology
[0002] Before high-temperature heating elements are used in equipment, their performance must be tested. Directly applying untested heating elements to equipment can lead to various problems, including safety hazards, performance defects, and economic losses. For example, unstable heating elements can cause temperature fluctuations that affect product quality; defective heating elements may suddenly fail, causing equipment downtime and disrupting production plans; degraded heating elements will reduce heating efficiency and increase energy consumption; unstable heating element performance can damage thermocouples, power modules, insulation layers, and other components, shortening the overall equipment lifespan; frequent replacement of heating elements or repair of related components increases equipment maintenance costs, etc. Current heating element testing methods directly connect to electrical equipment, judging the heating element's performance by measuring current, voltage, and other data under energized conditions. However, existing heating element performance measurement equipment typically exposes the heating element, posing safety hazards and making the measured temperature susceptible to external environmental influences, which can easily lead to inaccurate test data.
