Product Description

Product Information
"Vacuum circuit breaker" is named for its high vacuum extinguishing medium and the insulating medium of the contact gap after arc extinguishing; It has the advantages of small size, light weight, frequent operation and no maintenance, and is widely used in distribution network. Vacuum circuit breaker is a 3-10kV, 50Hz three-phase AC system in the indoor distribution device, for industrial and mining enterprises, power plants, substations as electrical equipment protection and control, especially suitable for non-oil, less maintenance and frequent operation of the use of places. Circuit breakers can be configured in middle cabinets, double cabinets and fixed cabinets to control and protect high-voltage electrical equipment.
The vacuum circuit breaker mainly includes three parts: vacuum interrupter, electromagnetic or spring operating mechanism, bracket and other components.

Characteristic:
1.The contact opening distance is small, the contact opening distance of 10KV vacuum circuit breaker is only about 10mm, the operating work of the operating mechanism is small, the mechanical part of the stroke is small, and the mechanical life is long.

2.The arc time is short, and has nothing to do with the size of the switching current, generally only half a cycle.
3. The recovery speed of the contact gap medium after quenching is fast, and the fault performance in the near area of breaking is better.
4.Due to the small wear of the contact at breaking current, the electrical life of the contact is long, the full capacity breaking is 30-50 times, the rated current breaking is more than 5000 times, and the noise is small and suitable for frequent operation.
5. Small size, light weight.
6.Suitable for breaking capacitance load current.
Because of its many advantages, it is widely used in substations, the current models are mainly: ZN12-10, ZN28A-10, ZN65A-12, ZN12A-12, VS1, ZN30 and so on.
Product Details
China began to develop vacuum switches in 1958. In 1960, Xi 'an Jiaotong University and Xi 'an Switch Rectifier Factory jointly developed the first batch of 6.7 kV vacuum switches with a breaking capacity of 600 A. Then it is made into a three-phase vacuum switch with 10 kV and a breaking capacity of 1.5 kV. In 1969, Huaguang Electronic Tube Factory and Xi 'an High Voltage Electrical Apparatus Research Institute made 10 kV, 2 kV single-phase fast vacuum switch. After the 1970s, China has been able to independently develop and produce various specifications of vacuum switches.
Vacuum circuit breaker technical standard Vacuum circuit breaker has developed vigorously in China in the past ten years. The products have developed from several varieties of ZN1 to ZN5 in the past to more than dozens of models and varieties, the rated current reaches 5000A, the breaking current reaches a good level of 50kA, and has been developed to a voltage of 35kV.

Product manufacturing process

Zw32-40kv Outdoor High Voltage AC Vacuum Circuit Breaker of Intelligent Permanent Magnet

First of all, the first step in the manufacture of vacuum circuit breakers is to select materials. The choice of material is very important, because the vacuum circuit breaker needs to have good insulation properties and mechanical strength, it can bear affected by high voltage and high short circuit current. Common materials are copper, steel and ceramics.

The next step is the processing of the parts. The vacuum circuit breaker consists of many parts, including circuit breaker body, mechanical motion mechanism, electromagnetic components, etc. These parts need to be imported line accurate machining and assembly to ensure its reliability and stability.

After the parts are processed, the assembly of the vacuum circuit breaker can begin.

First of all, each part is assembled on the circuit breaker body, and debugging and calibration.

Next, the electromagnetic component is installed in the appropriate position and the control line is connected. In addition, it is also necessary to
adjust and test the mechanical motion mechanism to ensure its sensitivity and smoothness
how free it is.

After the assembly is completed, the vacuum circuit breaker can be tested and inspected. Through split the router conducts electrical characteristic tests, such as breakdown voltage test, breaking and closing test, etc.

To ensure that it meets design requirements and standards. At the same time, the appearance quality check is also required

and performance testing to ensure the quality and reliability of the circuit breaker.

Finally, after rigorous testing and inspection, the vacuum circuit breaker can be packed and processed leaves factory. Take anti-shock, moisture-proof, and anti-static measures to protect the circuit breaker integrity and security. The label and instruction manual should also be accurately affixed to the package to facilitate the user to understand and use.

In general, the process of vacuum circuit breaker includes material selection, parts processing, assembly, testing and inspection, packaging and delivery. Every step needs to be strict control and operate to ensure product quality and safety. Only through fine craftsmanship process, in order to create a high-quality vacuum circuit breaker for the stable operation of the power system and equipment protection to provide assurance.

Zw32-40kv Outdoor High Voltage AC Vacuum Circuit Breaker of Intelligent Permanent Magnet

Fields of application

Vacuum circuit breaker is widely used in power system.
The working principle of the vacuum circuit breaker is:
When the dynamic and static contacts are opened under the action of the operating mechanism, an arc is generated between the contacts, and the surface of the contacts evaporates steam at high temperature. Due to the special shape of the contacts, a magnetic field is generated when the current passes through, and the arc moves rapidly along the tangential direction of the surface of the contacts under the action of this magnetic field, and part of the metal steam condenses on the metal cylinder (shielding cover). The arc is extinguished at the natural zero, and the strength of the medium between the contacts quickly recovers.
