Control cabinet
The control cabinet is to assemble the switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-enclosed metal cabinet or on the screen according to the electrical wiring requirements. The layout should meet the requirements of the normal operation of the power system, easy to overhaul, and not endanger people. And the safety of surrounding equipment. During normal operation, the circuit can be switched on or off by means of the manual or automatic switches. In the event of malfunction or abnormal operation, the circuit will be cut off or alarmed with the help of protective appliances. The measuring instrument can display various parameters in operation, and can also adjust some electrical parameters to prompt or signal deviations from normal working conditions. Commonly used in various power generation, distribution and substations.
- The cabinet door is 25mm from the ground and 2.5mm thick mounting plate, with 20mm wide U-shaped flanges on both sides, making the mounting plate stronger and easier to handle.
- The three cable lead-in cover plates at the bottom of the box can be replaced by each other, which is convenient to move, easy to lead cables, and easy to open holes for cable entry.
- There are grounding bolts on the cabinet door. 5. The load-bearing hinge is easy to install and easy to change the cabinet door. The door can be opened at 130 °.
- The plastic sliding device can use the plastic sliding device to pass through the guide rail, and the mounting plate can be pushed into the cabinet from the front of the cabinet. 7. The sturdy rectangular frame can not only strengthen the strength of the front door, but also can be used to fix and install electrical components (with the door installed with horizontal bars).
- The back panel can be easily installed and fixed with screws; the cabinet door can also be replaced.
- Standard MS821 locks, locks the cabinet door at the top, middle and bottom three points.
- Sealing ring: Polyurethane foam sealing tape to ensure the protection level.
- Add a waterproof edge at the cabinet door frame to cooperate with the cabinet door sealing ring to prevent water and dust from falling into the cabinet.
- (Single door) The left and right interchangeable door opening design is convenient to use. The standard modularized mounting hole design is convenient for installation.
- Inner light, easy to install and test (optional).
- File bag, convenient for on-site work (optional).
- Installing beams can also be installed in the cabinet without using the mounting plate (optional).
- The fan and filter screen ensure the ventilation in the cabinet, and the protection level is IP54 (optional).
- The base, fixed, movable, and easy to disassemble and install (optional).
- Double mounting plates, large installation capacity (optional).

The control cabinet has reserved contacts to facilitate information feedback and remote control with the central control room. Control process: 1. When a fire occurs, manually press the system start button, delay 30s, the electromagnet is energized (power supply DC24V), open the start gas cylinder, the start gas instantly opens the drive cylinder head valve. 2. The driving gas is pressure-reduced into the dry powder tank through the pressure reducer. When the pressure in the dry powder tank reaches the working pressure of the equipment (adjustable), the detection feedback signal of the electric contact pressure gauge is sent to the control cabinet, and the control cabinet opens automatically The blasting powder electric ball valve (requires self-locking) for fire extinguishing and injection. 3. There is an emergency stop button on the control cabinet. When the fire information is wrong or there is no fire, the emergency stop button can be pressed to stop the system startup within 30s of pressing the system start button. 4. If the emergency stop button is not pressed after the delay exceeds 30s, the solenoid is energized and the starting gas cylinder is opened, the emergency stop button is invalid. 5. The control cabinet is required to be able to control the up, down, left and right of a fire monitor and display the running signal. | |||||||||||
