Explosion proof control cabinet for 4KW frequency converter in paint factoryProduct Features

1. This product is a composite type, and the switch box adopts an explosion-proof structure. The busbar box and outlet box adopt an increased safety structure. Adopting a modular structure, various circuits can be freely selected and combined.

2. Equipped with high breaking miniature circuit breakers, molded case circuit breakers, AC contactors, and various electrical components, with overload and short circuit protection functions.

3. This product has comprehensively launched a new optimized design scheme and operating mechanism, with a compact and reasonable structure, strong universality, flexible and convenient operation, and good hand feel.

4. All fasteners are made of corrosion-resistant 304 stainless steel fasteners.

5. Steel pipes or cables can be used for wiring.

6. Can be customized according to user requirements.

Product Features

1. The outer shell of this product is welded with high-quality steel plates or stainless steel, and the surface is subjected to high-speed shot blasting and powder electrostatic spraying, resulting in a beautiful appearance;

2. This product is an improved explosion-proof product of "Er Gong Electric", which can be installed with various ordinary detection instruments, analysis instruments, display instruments, transformers, soft starters, frequency converters, etc. according to user requirements

PLC、 Various buttons, switches, microcomputer touch screens, and ordinary electrical components are not restricted for users to install electrical components;

3. Adopting diverse designs, one can choose from cabinet style (top and bottom, left and right), wall mounted, piano table style, flat style, etc;

4. The distribution cabinet consists of a cabinet body, a control system, a gas distribution system, an alarm system, and a distribution system; Explosion proof components for the control system and user's power distribution system components installed in the positive pressure chamber

(We can also customize split or online according to customer requirements);

5. The air intake method of this left and right cabinet is ventilation type, which means uninterrupted continuous air supply. The working heat of the components installed in the positive pressure chamber can be carried away with the air path, which has a good heat dissipation effect.

6. This product is designed, manufactured, and inspected in accordance with GB3836.1-2000, GB3836.5-2004, and relevant standards.

Under the control of the automatic control system, the positive pressure cabinet is filled with protective gas, and the pressure inside the positive pressure chamber is higher than the pressure outside the positive pressure chamber, forming a safe small environment with slight positive pressure,

This prevents flammable and hazardous gases from entering the positive pressure chamber, ensuring the safe operation of ordinary instruments and electrical components inside.

7. The automatic control system mainly completes functions such as ventilation, air supply, automatic alarm for ultra-high pressure, exhaust, undervoltage alarm, and low pressure interlock power-off.

(This positive pressure cabinet has a low-voltage interlocking function, which automatically cuts off the user's distribution power supply to the positive pressure chamber when the air pressure is lower than the specified value (50Pa).)

This further confirms the safety and practicality of the product, as well as the explosion-proof control box for the mixer;

8. Protective doors can be installed according to customer requirements, which can display the display or action of internal control parts;

9. All fasteners are made of corrosion-resistant 304 stainless steel material;

10. Wiring methods include steel pipes, cables, and explosion-proof hoses;

11. It can be customized according to user requirements;

Product Features

1. Voltage vector PWM control method, low-frequency high torque output, low noise.

2. Adopting third-generation IGBT power device modules.

3. Fully digital design, 16 bit high-speed CPU, fully functional, easy to operate.

4. Equipped with a remote control panel, the control is reliable and convenient.

5. The voltage range of the power grid is wide, and it does not trip in the event of an instant power outage.

6. 7 sets for speed and 2 sets for deceleration time.

7. It has overvoltage, undervoltage, overload, overheating, instantaneous power outage, stall prevention, output circuit and fast fuse protection.

8. Power: 0.75-500KW

9. Voltage: 220V, 380V, 660V
