The cause of the constant temperature and humidity test chamber leakage and inspection method

Induction leakage: constant temperature and humidity chamber refrigeration everything is normal, each person must touch shell have hemp hand feel, cause the reason of this situation is inductive leakage. Constant temperature and humidity test chamber compressor, lighting lamps and lanterns in route from shell and inner cavity according to its own certain contact resistance; Induction motor, compressor motor is caused on the motor rotor and self-induction electric potential difference, the constant temperature and humidity test chamber without on wire harness, each person must touch shell will have hemp hand feel. Compressor leakage: compressor motor winding and the shell shell leakage caused by short circuit fault. Compressor leakage, shell working voltage is higher, close to the power supply voltage. Temperature controller leakage: for most of the constant temperature and humidity box temperature controllers are installed within the lining, the casing temperature shift will make temperature controller peripheral joint. When water injection temperature controller, temperature controller contact resistance between the shell and reduce leakage. The casing some electronics destroyed or transmission line embrittlement, damage caused by leakage. Constant temperature and humidity test chamber leakage inspection method: 1, check the user connector, switch power supply are all normal grounding device, wire connection have short circuit fault condition; 2, check the constant temperature and humidity box after connect power, refrigeration if everything is normal, each person must touch shell is a significant hemp hand feel; 3, the first to check the compressor dielectric strength, with a megger check of resistor is & ge; 20MΩ ; 4, the abnormal electronics temperature controller, light and outside the dielectric strength of the route to carry out the inspection; Constant temperature and humidity test chamber provides natural environment standard accuracy is part of China metrological verification based on our professional skills to formulate management authority of the metrological verification specification standard metrological verification after providing guarantee. Natural environment, therefore, must solicit experimental instrument can satisfying the metrological verification specification of all kinds of professional skills to the overall goals and precision request overall objectives, and on the application of moment not crossing the metrological verification cycle time standard by the deadline. Such as application is all over Taiwan in addition to satisfying the electric shocks of exciting force and frequency scale, load to professional skills such as the overall goals, there is also a necessary satisfactory calibration standard sideways shock than in the technical specification, ambry mesa instantaneous velocity proportions, harmonic distortion degree until the precision request overall objectives, and every application cycle time for two years after the metrological verification, across two years must start from scratch metrological verification standard to funding applications. The interpretation of the above is the constant temperature and humidity test chamber leakage causes and solutions, hope can help you, if you want to learn more about information of constant temperature and humidity test chamber, welcome to the online consulting service or call the company service hotline ( Website top right corner) For consultation, we will wholeheartedly provide high quality service for you!
