5、 Product features and structure
1. Features:
1) Ventilation and cooling device: the temperature ventilation and cooling system of the test box is automatically controlled by the temperature controller, and the cooling system is used in the box.
2) Wired transmission technology is used to control the black thermometer, which effectively improves the control accuracy.
3) Optical fiber transmission is used to measure the radiation intensity of xenon lamp to avoid the problem of measuring value error caused by temperature.
4) A black standard thermometer BST is installed on the sample holder
5) In order to record the working time of each test, the equipment is equipped with a timer on the operation panel, which can control the time of the equipment, and the equipment will automatically shut down when the timer ends.
6) Protection device: In order to make the xenon arc lamp work normally and not easily damaged, the xenon lamp automatically turns off when opening the door and the whole machine stops working.
2. Integral structure: composed of test box, heating/lighting/system/electrical control.
3. Inner box structure:
1) The air-cooled xenon lamp has a lamp tube placed side by side with a distance of 100mm;
2) The lamp is installed directly above the inner box and is separated from the inner box by a filter;
3) The conical structure above the inner box, such as the lampshade, is conducive to more uniform illumination of the light source;
4) A parallel sample rack is installed in the middle of the inner box, and the sample installation height can be adjusted by 50mm per grid. The appropriate height can be adjusted according to the size of the sample;
5) An irradiance sensor is installed in the middle of the sample holder.
6、 Refrigeration system
The main refrigeration components of the xenon lamp aging test chamber are the French Taikang compressor, which uses R404 and R23 DuPont environmental protection refrigerant respectively. The compressor of this brand has been proved to be a stable refrigeration accessory for medium equipment after decades of test and use. The compressor is the most closed type, and its structure is simple, but it is durable.
6、 Heating system
High-frequency heating wire is very important in this system. Improperly selected heating tube has short service life and is easy to cause funnel short circuit, which is extremely inconvenient and distressing for users with high requirements, and seriously affects the production inspection progress. For this reason, our company has developed the latest ceramic heating frame. The ceramic material has high temperature resistance, good insulation, and will not produce leakage and short circuit. The heating wire imported from Germany is connected in the middle, with thick wire diameter, high temperature resistance, and dry burning resistance. The quartz glass tube is installed in the middle of the heating wire, and its important function is to prevent the heating wire from softening and falling when it burns red, and the production heating wire and the metal in the inner box contact to produce short circuit and other fault phenomena.
8、 Security protection system
The safety protection system is the most important for the user, and setting multi-layer protection is an important measure to protect the user.
1. Line sequence protection: three-phase power is easy to be out of phase or the line sequence is opposite, which may cause equipment damage or accident to the tester.
2. Leakage protection, the use of unqualified heating wire or humidifier tube is enough to cause electric shock accidents.
3. Over-temperature protection. The use of controllers with poor quality brands may lead to temperature runaway and fire accidents.
4. Abnormal protection: when a certain indicator of the equipment operates abnormally, the equipment will automatically prompt the alarm reason and solution, and suspend the equipment operation at the same time, and wait for the maintenance personnel to solve the problem before operation.
