How to install components in positive pressure type explosion-proof power distribution cabinet

Positive pressure type explosion-proof power distribution cabinet can also be called positive pressure type explosion-proof cabinet, explosion-proof fume hood, explosion-proof compensation cabinet and so on. Explosion-proof positive pressure cabinets are widely used in petrochemical, offshore drilling platform metallurgy, medicine, light industry, textile, food, bioengineering, aerospace engineering and military facilities.

With the development of society, the use of explosion-proof positive pressure cabinets is more and more extensive, so how to install the components in the explosion-proof positive pressure cabinet?

First, the positive pressure type explosion-proof power distribution cabinet can be installed according to user requirements of various common monitoring instruments, analytical instruments, display instruments, micro-computer touch screens and ordinary electrical components, and the user-installed electrical components are basically not restricted.

Second, since the components of the power distribution system in the cabinet are installed by the user, the user must install and debug in the safety zone.

3. Do not remove the electrical components on the panel to avoid affecting the airtight performance of the cabinet.

4. The low-pressure interlocking contactor is installed in the positive pressure chamber. The user should interlock the power supply of the main power distribution system through the low-voltage interlocking contactor, so that when the pressure of the positive pressure chamber is too low, the main power distribution power supply is cut off by the contactor. .

5. When the user is wiring, please pay attention to the sealing performance of each incoming and outgoing cable, and use the explosion-proof glue for proper sealing treatment according to the tightness of each power.

6. After the user has finished wiring the wiring, the user must ensure the sealing performance.
