The intake solenoid valve closes, and the bypass relief valve replenishes air to the cabinet through the relay, maintaining the pressure gauge between 200~300Pa. That is, the cabinet enters the self-starting state and supplies power to the "contactor" in the positive pressure chamber, allowing the main circuit to operate normally, meaning the commissioning of the explosion-proof positive pressure cabinet is complete.。

During the use of the explosion-proof positive pressure cabinet, when the working pressure drops below 100Pa, the explosion-proof warning light alarms and enters the undervoltage protection alarm state; when the intake fault is not cleared and the cabinet pressure drops below 50Pa, the control system will disconnect the power supply to the positive pressure chamber; the system remains in the undervoltage protection alarm state (which can be cleared by pressing the "Mute" key); this is the undervoltage protection and electrical interlock process.。

When the pressure in the positive pressure chamber exceeds 400Pa, the pressure relief valve opens. After a period of time, the pressure in the positive pressure chamber gradually decreases, keeping the pressure inside the cabinet within the normal working pressure range, and the valve closes.。

1. During transportation and installation of the explosion-proof positive pressure cabinet, inspection should be strictly carried out in accordance with the inspection and commissioning specifications for low-voltage complete equipment.。

2. Compare the explosion-proof positive pressure cabinet with the technical accessories included with the box (assembly process drawings, etc.) and the user's design drawings one by one, and conduct regular inspections and operations.。

After commissioning is complete, it can be put into use.。
