The advantages of explosion-proof cabinets are as follows: 1. Power switching and protection: The variable frequency cabinet is equipped with a low-voltage molded case circuit breaker connected to the incoming power supply. Besides enabling the connection and disconnection of circuits, it can also protect against short circuits and overloads that may occur in the circuits and variable frequency drives. And the power can be cut off during maintenance. 2. Start/stop control function: The frequency conversion cabinet panel is equipped with buttons for starting and stopping the frequency conversion process, which are used to control the operation of the frequency conversion unit and facilitate on-site operation. 3. Frequency (speed) adjustment: A frequency adjustment potentiometer is provided on the control panel of the inverter, allowing for easy manual adjustment of the inverter’s output frequency in order to control the motor speed. 4. The table header shows that the inverter cabinet panel is equipped with a voltage meter, ammeter, frequency meter, as well as various indicator lights such as power indication, alarm indication, operation indication, and mains frequency indication, enabling monitoring of the inverter’s input voltage, output current, output frequency, and various operating conditions. 5. For users who require a backup AC power supply, frequency conversion cabinets with such a feature are available; in the event of a failure of the frequency converter, the motor can be switched to the AC power supply through an automatic control circuit. This mode can be set to manual or automatic, and for motors with a power rating of over 15 KW, a soft starter is used for starting. 6. Various control functions can be configured on the panel of the frequency conversion cabinet, depending on the operating conditions of the system: controls such as forward rotation, reverse rotation, increasing motor speed, decreasing motor speed, momentary forward rotation, momentary reverse rotation, manual/automatic mode, emergency stop, switching between frequency conversion and AC power supply, PLC control, and touch screen control are all available. 7. Installation of peripheral equipment: Depending on the operational requirements, an AC input reactor, an output reactor, a DC reactor, and +EMI+ filters can be installed in the frequency conversion cabinet, along with braking units, braking resistors, contactors, intermediate relays, thermal relays, a programmable controller (+PLC+), a programmable operation terminal (+GOT+), electricity meters, cooling fans, and more. 8. Safety protection: Installing the inverter inside an inverter cabinet helps to reduce environmental pollution and the risk of electric shock, providing good safety benefits. Application areas: a) Areas with explosive gas mixtures: Zones 1 and 2; b) Areas with explosive gas mixtures of categories IIA, IIB, and IIC; c) Temperature category: T4; d) Indoor and outdoor use. Product features: 1. The main and auxiliary cabinets can be arranged either side by side or one above the other. The main cabinet features a positive-pressure sealed chamber with doors at the front and back, along with an observation window on the front side, while the auxiliary cabinet is used to house the positive-pressure air circuit control system. 2. It features motion functions such as automatic ventilation before startup, ventilation delay, automatic air replenishment, and automatic control of the positive pressure range. 3. It is simple and easy to operate; once ventilation is complete, it enters the “positive pressure operation” state. 4. It features interlock protection functions such as positive pressure protection (upper and lower limits), audio-visual alarms, automatic power shutdown at the critical lower limit of positive pressure, power shutdown when the door is opened, and emergency manual power shutdown. 5. Cable crimp-type introduction device. 6. Various instruments, frequency converters, PLCs, soft starters, and computer control systems can be installed inside the product, enabling local as well as remote control.
