Detail
The circuit-breaker VB4-12(24) is the newest equipment in the voltage class of 12kV up to 24kV manufactured by Zhejiang Farady Electric Co., Ltd. It is universal used in power distributing and transforming systems of power stations, power generators, and secondary substations of mines, industries and infrastructures.

The circuit-breaker VB4-12(24) has complete type specifications:
the rated voltage is 12kV, the rated current is up to 4000A and the rated short circuit breaking current is up to 50kA.

The circuit-breaker VB4-12(24) is equipped with modularized spring operating mechanism which has characteristic of more convenient maintenance, rapider replacing of parts and more reliable performance.

The circuit-breaker VB4-12(24) adopts embedded poles that the vacuum interrupter with low resistance and the primary main electrical circuit are cast in insulating cylinders by epoxy resin.
This structure makes the breaker have more reliable insulation.

The embedded poles of circuit-breaker VB4-12(24) have the technique of ventilation and convection. Besides, the vacuum interrupter is with low resistance. All of these reduce the power consumption and the temperature rising due to the longtime running of circuit-breaker.

The circuit-breaker VB4-12(24) has perfect performance when it is breaking short-circuit current or being operated frequently.

Beside that it also has the functions of automatic reclosing and reliable operating.
The driving mechanisms of circuit-breaker VB4-12(24) are designed by professionals in CooperNature and with characteristic of reliable closing performance, low impact force and longer lifetime. The mechanical lifetime can be up to 30000 cycles.
performance is ensured. The circuit-breaker is also applicable to humid and hot regions.

The circuit-breaker VB4-12(24) has been through the whole type test in accordance with the standards of GB and IEC.Farady Quality Toyota Price Withdrawable Vacuum Break Switch

1.Electrical control
The modular control circuit board adopts the connection plug with the self-fastening function, which can ensure the reliability of the electrical connection. It also has the function of trip-proof and monitoring.
Tripping and closing coils adopt fully sealed structure to reach strong humidity resistance. The metal shell can ensure the good electromagnetic shielding.
Magnetic blow-out micro-switch is adopted to ensure the accurate signal indication
2.Closing system
Special steel tension spring can ensure the persistence and steady of the mechanical property. Self-lubrication beating is adopted to ensure the mechanical life can reach more than 50000 times. The cam shape is optimized through rigorous engineering to ensure the excellent output performance.

3.Energy storage system
High quality motor can ensure that the continuous operating life is up to 100,000 hours or more.
The gear transmission structure can avoid the risk of fracture.
4.Holding structure
The integral design of closing holding and separating brake release can ensure that the structure is simple and reliable, which can stop the fault of opening and closing.
The latch is casted with high performance steel and matched with accurate heat treatment process to ensure its long life.

5.Surface treatment
More than 90% of the component adopt the electro less nickel-phosphorus plating process and the standard items are taken stainless steel to enhance the corrosion resistance, the salt spray test exceed 500 hours.
6.Breaking brake buffer
Special cushioning mechanism design can buff the impact of the opening operation effectively.
Accurate damping control can ensure the perfect performance of the opening operation.
The aircraft hydraulic oils have excellent low- temperature viscosity which can ensure the reliable operation of the circuit breaker.
Embedded Pole
High Reliability
Compared with the traditional assembled pole, the number of parts, conductor connection surface connecting fasteners used for the Embedded Pole can be reduced by a big margin so as to simplify the assembly procedure of the main circuit, lower the circuit resistance and enhance the reliability of the main circuit connection.
Stable Insulating Property
After the vacuum interrupter is embedded in the solid epoxy resin material, the external environment of the pole can make the lowest effect on the vacuum interrupter. With the external insulating capacity, the pole can not be affected by dust, humidity, small animals, condensation and pollutions. It can completely meet the creepage distance requirement of the II-grade polluted region specified in the GB/DL Standard.
Firm Structure
Provide the sufficient protection for the vacuum interrupter so that it can not suffer the accidental mechanical collision in the process of assembling or transportation.
Miniaturization
Adopt the epoxy resin as the insulation medium to reduce the phase distance and decrease the volume of the vacuum circuit breaker & its matching switch cabinet.

Free Maintenance
As the whole pole is poured into the integral component, the vacuum interrupter can get the sufficient protection. The free maintenance of the vacuum interrupter can provide the condition for the free maintenance of the circuit breaker.

More Environmental Protection
The circuit breaker with the Embedded Pole can substitute for the SF6 gas as the external insulation to some extent, with more environmental protection.
