Reasons for fracture of quartz transition joints
In the power system, a large amount of conductive material needs to be consumed. The terminals of many devices are made of copper, and most of the overhead lines are made of aluminum. Therefore, aluminum wires are widely used. If it is directly connected, the contact resistance will be high. When the equipment is running for a long time, overloaded or short-circuited, the connector will quickly heat up, and the heat will be transferred to the electrical equipment, such as a transformer. On the other hand, the contacts will burn out and the lack of phase operation will cause a power outage, on the other hand, it will cause the equipment to burn out. Therefore, power systems generally use specially processed and welded quartz transition joints. However, the current level of technology makes it impossible to weld joints to be perfect.

The use of quartz transition joints and installation precautions
Quartz transition joints are widely used in today's life, especially in pipe connection and cable laying. It has become one of the indispensable tools, especially in the development of new infrastructure. As the most mainstream joint product at present, I will take you to understand the purpose of transition joints. What problems should be paid attention to in use?

Some knowledge points of quartz transition joints
When buying and using quartz transition joints, people usually think that they are very smooth. This has also led some people to understand that transition joints can only be reserved for purchase and use. In fact, in addition to these, it is also part of the need to maintain. Inspections should be carried out before and after installation to avoid affecting the use or normal use of the transition joint. In the actual inspection process, there are still many inspections.

How to choose a flame detection photocell manufacturer?
1. Search and select manufacturers through the Internet Now, with the development of the Internet, no matter what we buy, we are accustomed to finding what we want on the Internet. Almost all companies put themselves in the wave of the Internet, so it is easy for us to make a choice. We can find more flame detection photoelectric cell manufacturers through the Internet, and then make a series of comparisons, and there is no need to find a good one. 2. Select strong manufacturers Everyone wants to choose an excellent and capable manufacturer. This is understandable, but how does the strength of the flame detection photocell manufacturer reflect? Strength is not to speak out
Features and characteristics of flame sensor
The flame sensor, which is a digital and analog dual input module, can realize flame detection and is suitable for all occasions that require flame detection, such as fire extinguishing robots and flame alarms. Characteristics of flame sensor: 1. It adopts five-channel flame sensor design, which has a wide detection range. 2. It can output digital signal (high and low level), easy to use. 3. It can output analog signal (voltage signal), suitable for high-precision occasions. 4. All five outputs have status indicators, which brings great convenience to debugging and actual use. 5. The detection distance of digital output is adjustable, modulus
Principle of flame sensor
The flame sensor is a sensor specially used by the robot to search for the fire source. Of course, the flame sensor can also be used to detect the brightness of the light, but the sensor is particularly sensitive to flames. The flame sensor uses the characteristic of infrared light to be very sensitive to flames, uses a special infrared receiver tube to detect the flame, and then converts the brightness of the flame into high and low level signals and inputs them to the central processing unit. The central processing unit performs corresponding procedures according to the changes in the signal. handle.
