Composition of Electrical Components of High and Low Temperature Test Chamber

Composition of Electrical Components of High and Low Temperature Test Chamber

The main parts of the high and low temperature test chamber are refrigeration units, condensers, evaporators, and controllers. The main parts play a key role, so everyone pays special attention to its main parts raw materials. However, most of them ignore its auxiliary parts at this time, or feel that the role of auxiliary parts is not worth noting. Few people want to count the specific parts, so it is not clear what specific electronic components are fully used in the constant temperature and humidity test chamber.

1, Refrigeration unit:

Used to control the operation of refrigeration unit, to carry out refrigeration cycle, and there are single-phase and three-phase.

2, Fan motor:

Used to control the fan circulation steam body, heat exchanger heat conduction, and there are indoor and outdoor. 

3, Electric heater equipment:

Used for heating indoor air quality quality, tubular, flocculent points.

4, Timer:

Used for automatic control system timing boot.

5, DC contactor:

Used for refrigeration unit motor breaking and connection.

6, Leakage protector power switch:

It can not only connect or disconnect the main circuit like other switches, with the effect of leakage current detection and discrimination, when the main control circuit caused by power outage or cable sheath damage, leakage protection switch power supply main switch can be connected or disconnected switch components according to the identification results. It can be combined with isolation switch and heat relay to form a full-function low-voltage switching electronic device.

7, Overtemperature protection equipment:

Its role can not be ignored, when the controller temperature is not sensitive, the implementation of the E double maintenance of the box overtemperature, when the alarm is caused, the maintenance standby, the alarm will be different with the test temperature, relative change, you can further have the role of overtemperature maintenance. The basic concept is that when the total current flow of the broken wire exceeds the limit value, the temperature of the broken wire rises and the broken wire is broken. When the heat value caused by the broken wire does not exceed its short circuit capacity, the balance between the heat value and the released heat value is guaranteed, the temperature of the broken wire cannot reach the melting temperature, it is not easy to break.

Like this kind of small electronic components, in the high and low temperature test chamber looks innocuous, but for the structure of a test chamber is also very useful, without these components, a test chamber is not used, in short, the details determine the success of failure, fine without size, in the grasp of the test chamber at the same time, more should be from its key links to grasp.
