Product Features

Aluminum alloy shell or steel plate welding, surface spraying;

Equipped with frequency converters, circuit breakers, signal lights and other components produced by companies such as Fuji or Schneider;

It mainly adjusts the speed of ordinary three-phase asynchronous motors by changing their output frequency to meet production process requirements or achieve electrification. The energy-saving rate can reach 30% -60%, and it can also

As a starting controller for electric motors, it can also form a closed-loop speed control system through control circuits such as sensors and transmitters. The installation and operation are simple, the power factor is constant, and it has various functions such as fault display;

It has multiple protections such as overcurrent, short circuit, overvoltage, undervoltage, and circuit breaker. It can digitally display frequency, speed, load rate, or current, and can manually adjust the frequency. It can also set the process curve of speed changing over time, and the frequency can be controlled by the DCS system providing signals;

Steel pipe or cable wiring.

Ordering Notice:

When ordering, the number of branches of the matching box and the corresponding number of poles of the current carrying circuit breaker for each branch should be specified. If leakage protection function is required, please indicate that the explosion-proof frequency converter welding box is professionally customized

If a main switch is required, please indicate the current and number of poles of the main switch, as well as the direction of incoming and outgoing lines, specifications of incoming and outgoing lines, and corresponding quantities;

The required series of explosion-proof distribution boxes can be specially designed according to user requirements, and users need to provide electrical system diagrams.

Applicability of explosion-proof distribution box:Customized explosion-proof distribution cabinet with built-in frequency converter

With the rapid development of industries such as petroleum, chemical, and mining, explosion-proof distribution boxes are becoming more and more widely used in production, storage, and rescue, with an increasing variety. How to prevent accidental explosions of explosion-proof distribution boxes in explosive gas hazardous areas has become a very important issue. Due to the inevitable generation of electrical sparks during the operation of explosion-proof distribution boxes, once they come into contact with explosive gas mixtures at production or rescue sites, it can lead to explosive accidents, directly endangering national property and the safety of citizens' lives. Therefore, as the most widely used lighting fixture, its explosion-proof technology has already attracted widespread attention and high attention from people.

Characteristics:

1. The explosion-proof distribution box adopts a composite and modular structure, and each circuit can be freely assembled according to needs. Generally, the switch box adopts an explosion-proof structure, and the busbar box and outlet box adopt an increased safety structure

2. The internal components can be installed with high voltage circuit breakers or molded case circuit breakers according to user requirements. Such as DZ47, C65, CM1, etc. Component brands such as Chint, Schneider, Delixi, Changshu, etc

3. It can be customized according to customer requirements, such as installing surge protectors, ammeters, voltmeters, etc., and can also be equipped with padlock metal handles. 4. Suitable for lighting and power lines, with functions such as disconnection, overload, voltage loss protection, and automatic short-circuit cut-off. Steel pipes or cables can be used for wiring.
