Electric heating tube is a common type of electric heating device, which is widely used in various industrial and civil fields due to its simple structure and convenient use. However, during use, there may be situations where the heating tube leads are burnt out, which can affect their normal use and even cause safety hazards. This article will analyze the causes of lead burning and introduce corresponding solutions.
The main reasons for wire breakage are as follows:
1. Poor contact of leads
If the lead of an electric heating tube has poor contact or the contact point is affected by factors such as corrosion and oxidation, it will cause overheating when the current passes through the lead, thereby burning the lead.
2. Overload usage
Overload usage is one of the main reasons for lead burnout. If a 220V electric heating tube is connected to a 380V power supply for use, or if a high-power electric heating tube is used in a small capacity heater, it will cause the heating tube to be subjected to excessive current and power load, which will increase the lead temperature and ultimately burn out.
3. The working environment of the heating tube is harsh
If the working environment of the electric heating tube is harsh, such as high temperature and humidity, it will damage the insulation material inside the heating tube, causing current to bypass the heating wire and flow through the lead, leading to the burning of the lead.
To solve the problem of lead burning, we can take the following measures:
①Choose the appropriate voltage and power
When purchasing electric heating tubes, it is necessary to choose the appropriate voltage and power according to actual usage needs. If the voltage and power of the heating tube do not match the usage requirements, it will lead to overload use, leading to problems such as lead burning.
②Check the connection of the heating tube leads
When installing electric heating pipes, ensure that the leads are firmly connected and in good contact. At the same time, regularly check the connection of the heating tube leads to avoid burning due to poor contact of the leads.
③Keep the working environment of the heating tube clean and dry
The working environment of heating pipes should be kept clean and dry to avoid damage to insulation materials due to harsh environments.
In summary, there are many reasons for the burning of electric heating tube leads, such as poor contact at the lead joints, improper selection of lead materials, and high pipe wall temperature. To avoid these problems, it is recommended to choose manufacturers with guaranteed quality and exquisite craftsmanship when purchasing heating pipes, and avoid choosing inferior products with low prices. At the same time, during installation and use, it is also necessary to follow the correct method, and do not arbitrarily change or modify the leads and joints of the heating tube to avoid causing safety hazards. If encountering problems, seek the help of professional technical personnel in a timely manner for repair and replacement. I hope this article can be helpful to you and help you better understand the problem of lead burning in electric heating tubes and its solutions.
