Switch is very common at home, whether it is lighting or electrical appliances need to use the switch, but there are some switches at home is not commonly used, such as air switch, I believe that people who have not been contacted are very strange to it, what is the air switch What? What is the price of the air switch?
First, what is the air switch
What is an air switch? The presence of an air switch in a low-voltage distribution network is very important. It is a necessary configuration in the home. In the popular sense, it is a circuit breaker. That is, once the current in the circuit exceeds the rated value, or the circuit is short-circuited or voltage overloaded, it will automatically A switch that is disconnected.
The air switch can not only complete the contact and breaking circuit, but also integrate control and protection functions. In the daily working life, there may be frequent circuit short-circuits and some power failures. When this happens, the power distribution system will generate large voltage and heat, which may cause damage to the home appliance. Even a fire accident can occur. Applying an air switch at this time can be more safe.
The air switch can trip the setting current value at the moment when the short-circuit current exceeds, so that the hook disengages the rotation shaft seat from the buckle, and the three main contacts are broken to cut off the power. When the voltage is overloaded, it will cause the heat element to generate a certain amount of heat, prompting the bimetal to be heated and bending upwards, so that the hook and the buckle will be disengaged, and the main contact will be broken to cut off the power.
Second, the air switch price
1, different rated air switch prices
There are gaps in the price of air switches with different rated currents. There are 10A, 16A, and 20A. When we purchase air switches, we must purchase them according to actual requirements, which may take around 30-40.
2. Air switch prices for different poles
Different pole configuration air switch prices are also different, the number of poles 1p, 1p + n, 2p, 3p and other poles, is also based on the actual situation of the old configuration to buy, the general high number of higher prices more expensive, its market The price is probably between 20-40 yuan.
3, different brands of air switch prices
Of course, the price of different brands of goods is different, the same air switch, domestic brands of air switch prices are generally ranging from 20-80 yuan, while the imported air switch prices are more expensive, probably more than 100 yuan, and even have Thousands of dollars.
4, different purchase price air switch channels
Air switches bought in different places are also cheaper. In general, the air switch purchased by the Internet will be cheaper than the physical store, and the same product may be 20%-30% lower.
5, different circuit breaker air switch prices
The air switch is mainly composed of circuit breakers, and the prices of circuit breakers of different quality are also different. The circuit breaker configuration with very sensitive short-circuit overload protection function is such that the market price is around 300 yuan.
Editing summary: The above is about what is the air switch and the air switch price how many introductions, hopes that the content that Xiao Bian brings can help everybody, lets everybody better understand, uses the air switch, if you want to know more related knowledge , You can follow our website information.
What is an air switch
As an excellent high-temperature engineering material, Si3N4 ceramic block has the most advantage in its application in high temperature fields. The future development direction of Si3N4 is: (1) to fully utilize and utilize the excellent characteristics of Si3N4 itself; (2) to develop some new flux during the sintering of Si3N4 powder, to study and control the optimal composition of existing flux; (3) to improve milling , molding and sintering process; (4) development of Si3N4 and SiC and Other Materials, in order to obtain more high-performance composite materials.
