Product Description

 

Material: Alumina Ceramic, Al2O3, Aluminium Oxide
Today about 80 percent of power network operators decide in favour of vacuum switching technology. The core component of this switching principle is the vacuum interrupter. Vacuum Interrupters are used for repetitive switching, motor in rush current interruption, fault protection, over current and short circuit protection. They can reliably switch high stress currents robustly without the need for unreliable cooling or ventilation systems.

Product Feture


Long Life & High Reliability
Fast Interrupting Speed
Rapid Dielectric Recovery

Applications


1. Circuit breakers
Vacuum interrupters are used in circuit breakers in the most demanding electrical circuit protection applications to minimize damage caused by electrical overloads or short circuits.

2. Load break switches
Vacuum interrupters are used in load break switches to connect and disconnect electrical load currents providing limited load switch capacity.

3. Reclosers
Vacuum interrupters are used in reclosers to automatically open and close distribution circuits in response to transient overload and fault conditions.

4. Contactors
Vacuum interrupters are used in contactors in demanding applications that require a high number of operations switching a power circuit in electric motors, lighting and heating devices, capacitor banks, and the like.

5. Tap changers
Vacuum interrupters are used in tap changers inside transformers to change the winding connections to deliver the required voltage.

6. Railway circuit breakers
Vacuum interrupters are installed in the circuit breakers on top of this special locomotive to supply electrical energy to railway locomotives' electric drive motors.

Q:How do we calculate the bulk shrinkage of ceramics?
With the length before contraction minus the length of the contraction, and then divided by the length of the contraction before the line shrinkage, the general body contraction rate is three times the first contraction, you can get the body contraction rate! Personal views are for reference only!
Q:The ceramic vase is broken. What can stick it up?
Put in sunny place, dry a water after, evenly coated with broken surface cracks, after the alignment, hard pressed, static two days after the good. And strong, not strong, not open, some of my tiles are so sticky. You can try, do not use glue or glue material, it will damage the tread glaze.If you want to use water, do not use garlic juice, garlic juice is to watch the machine repair, with second kinds of gypsum, this does not affect the use, but also can be solidGypsum can also be used if conditions permit. The plaster is mixed with fresh egg white and mix into a paste, coated with two fracture plane, aligned hard pressed don't hard, even hard on the line, and then put the napkin surface spilled egg white clean, placed two or three days should be good. But it's better than garlic juice
Q:Is purple pottery made of pottery?
Purple clay produced in nearby Yixing Dingshu hills, there are purple clay, green clay and red clay, three. In the firing process, the surface does not glaze, the natural clay color is precisely its characteristic. Purple clay can be made into pottery pots, pottery bottles, pottery pots, and sculptures, among which the teapot is represented.So it's ceramic
Q:Ceramic pot for a long time, how to clean the dirt?
Very simple, heating water soak overnight, second days just wash. No, just one more night.
Q:What are the cermet coatings?
Polymer bonded polymerization method, KN17 polymer ceramic coating is applied to anti-corrosion, such as corrosive slurry pipeline.
Q:Where is the difference between ceramics and ceramics?
Five glaze differentPottery has two kinds of glazes without glaze and glaze. Glazed glazes can be melted at lower firing temperature. There are two kinds of glazes in China, which can be burnt once in a high temperature with the carcass, and also in low temperature and high temperature, and then hung with low temperature glaze, second times low temperature.In the above several aspects, the most important condition is the raw material and the firing temperature, several other conditions are closely related with these two. Therefore, once the master of pottery mastered the technique of burning temperature and realized the difference between kaolin and general clay, he would have the condition to invent porcelain.
Q:Who was the pioneer of China's ceramic road in ancient times?
The maritime Silk Road (also known as "ceramic road", "spice road") is the sea channel of ancient China and foreign transportation of trade and cultural exchanges, it is mainly from the East China Sea Route (or Wyoming from Yangzhou (now Ningbo) by North Korea or Japan direct route) and South China Sea route (starting from Guangzhou to the Southeast Asian countries, or the Malacca Strait, into India ocean, the India, Sri Lanka, Pakistan route to the Persian gulf. At that time, some ships continued along the Arabia Peninsula west Africa), was formed in the Qin and Han Dynasties, developed in the Three Kingdoms period of the Sui Dynasty, flourished in the Tang and Song Dynasties, changes in the Ming and Qing Dynasties, is the most ancient sea routes known.
Q:Why should the shell of the tank be covered with ceramic?
High temperature ceramic and very durable on the outside of the fight force is better than steel armor, the armor now in the study of ceramic armor technology, ceramic armor has been widely used in the reaction tank, the facts also prove that this armor has good defensive ability, plug-in reactive armor can receive blow off can buffer off a part of impact force.
Q:What are the new ceramic products?
fine ceramicsThis new type of precision ceramic building materials) a Japanese company developed is a mainly composed of water soluble latex powder, such as 100 grams and 20 grams of cement cell ceramic in the effect of hydrolysis of a mixture of calcium, will completely eliminate the effect of hydration occurred in the degrees of freedom, can make life extension 4 to cement 5 times tolerance degrees Celsius when using non water model (plastic mold, can be obtained with the same ceramic luster.
Q:The production process of Ceramic Decal
Design (colour removal) ---- drying the net ---- printing (colour) ---- sealing glue ---- packingAskCan friends simply describe in words? I'm a layman. It's too easy to understandChasing the answerCeramic decal printing process with other printing the same basic difference is that the pigments used different (pigment resistance 750----1280 degrees Celsius) if you need to a process in which further understanding, can byte search, there are specific links do not understand can ask me.Don't say love copy a lot as the answer as if it were raining flowers.
