Introduction to DMX2 series circuit breakers

The DMX2 series magnetic field circuit breaker is an improved product of the original DMX series. Our company has studied the usage, user feedback, and existing problems of the original DMX series magnetic field circuit breakers over the past 10 years. In order to improve product quality, we have made multiple improvements, including a few

Example:

(1) Without changing the overall width of the arc extinguishing chamber, making full use of the limited space, increasing the width and length of the arc extinguishing chamber and grid is more conducive to the cooling and extinguishing of the arc. The gap of the grid plate has been changed from the middle to one side and installed in a staggered manner, reducing the resistance when the arc enters the grid plate and improving the arc extinguishing effect.

(2) Extending and widening the upper and lower busbar of the original circuit breaker has maintained sufficient conductive contact area and reduced the temperature rise of the circuit.

(3) Thicken the original side plate, auxiliary contact installation plate, manual closing components, etc; Several vulnerable and thin parts have been reinforced, such as increasing the synchronization and distance adjustment screws of the contacts, thickening the torque reset spring, etc. These modifications have extended the service life and made the use safer and more professional.

(4) Replace the skeleton free coil with a skeleton coil to ensure good installation and fixation of the coil, and stable operation of the electromagnetic mechanism.

(5) The micro switch has been replaced with imported parts from domestic parts, increasing the professionalism of the action.

(6) Improved the control circuit to avoid the occurrence of coil burning caused by closing errors. At the same time, secondary lead out terminals have been added for user convenience.

Main features of DMX2 magnetic field circuit breaker:

1. The snap on contact structure is installed on the same rotating insulated square shaft, and the action is synchronized; Different capacity contacts and arc chambers can be combined to form circuit breakers with different current and voltage levels. It can meet the needs of demagnetization matching for large, medium, and small capacity generator sets at home and abroad, as well as the special requirements of ZnO nonlinear resistor demagnetization for arc voltage. Compared with similar products at home and abroad, it has advanced performance, simple structure, professional action, and creativity.

2. The unique transmission mechanism of electromagnetic closing, permanent magnet holding, and demagnetization opening replaces traditional mechanical locking devices, requiring no maintenance and greatly improving the protection professionalism and service life of circuit breakers.

3. The arc extinguishing chamber, which is made by replacing the usual series arc blowing system and short arc principle with a long magnetic field, not only maintains professional breaking under low current, but also establishes a constant arc voltage, thereby maintaining professional commutation and demagnetization when the circuit breaker is disconnected.
