Multi-factor environmental simulation test box

Abstract

The invention discloses a multi-factor environmental simulation test box. The multi-factor environmental simulation test box comprises a work chamber, a tapered hopper, and an air pre-conditioning chamber, the generation of high temperature, low temperature, and wet and hot environment is integrated to a system arranged in the air pre-conditioning chamber, the air pre-conditioning chamber is connected with the work chamber via conveying circulation channels, the conveying circulation channels are both provided with valves, and a movable separating plate is arranged between the work chamber and the tapered hopper. During a dust test, the separating plate is moved away, and the work room is communicated with the tapered hopper; during other tests, the separating plate is inserted, sealed insulation of the work chamber is realized, the work chamber is completely separated from the tapered hopper, salt fog and dust are prevented from entering the air conditioning chamber, the corrosion of devices in the air conditioning chamber is prevented, the dust is prevented from entering an evaporator and adhering to an aluminum plate exchange membrane of the evaporator, and the influence on the refrigeration effect is avoided; rainwater is prevented from entering the inner side of the air conditioning chamber, and the influence on the refrigeration effect is prevented; and the space for illumination tests and system tests is increased.

Description

technical field [0001] The invention relates to an environment simulation test box, in particular to a multi-factor environment simulation test box. Background technique [0002] Devices such as electric energy meters, switches or insulators used in power systems need to resist various environmental factors in use to ensure their accuracy, safety, and stability during use. Therefore, these devices must undergo environmental simulation tests when they leave the factory. In order to achieve resistance to high temperature, low temperature, salt spray, dust, light and other environmental factors. There are many kinds of test chambers used in the current environmental simulation test, and each test needs to be carried out in different test chambers, resulting in waste of manpower, time and occupied space for transit, and increased test cost. Although some test chambers integrate high temperature and low temperature tests, if tests such as dust or salt spray are also integrated, ...

Problems solved by technology

However, in the test, the generated salt mist, dust, etc. will enter the air conditioning chamber, corrode related components, and affect the cooling effect

On the other hand, there are fragile products such as quartz glass nozzles and glass separatory funnels in the salt spray functional system components, and there are glass xenon lamp tubes and quartz glass filters in the solar radiation resistant functional system. Therefore, the test box with this integrated structure, the vibration when the fan is running, the vibration and impact when the vibrator is working, will cause great interference and damage to these components.
