High voltage composite insulator type classification and mechanism of insulator ( 绝缘子) : installed in the different potential between conductors or conductors and ground potential between artifacts, able to withstand voltage and mechanical stress the role of the device. Power (subject: Level 1 subject) ; Transmission line ( The secondary subject) High voltage composite insulator principle and function: high voltage insulator is a special kind of insulation control that can play an important role in the overhead transmission lines. Early years insulator for more poles, slowly development in high type high voltage wires to hang a lot at the end of the disc insulators, it is to increase the creepage distance, usually made of glass or ceramic call insulator. High voltage insulator in the overhead transmission lines with two basic role, namely support wire and prevent the current back, these two functions must be guaranteed, high-voltage insulator should not change due to environmental and electrical load conditions lead to a variety of electrical and mechanical stress and failure, or else there won't have a significant role in the insulator, will damage the whole line of use and operating life. Zero at the ends of the insulator is in operation of insulator potential distribution of insulator in close to zero or equal to zero. Zero or low insulator: the influence of the insulation of the line conductor depends on the insulator string, due to manufacturing defect or role of the outside world, the insulation of the high voltage insulator performance will continue to degradation, when insulation resistance lower or equal to zero is called the minimum or zero insulator. We have to test the circuit, and the proportion of zero or low insulator was about 9%. This is our company another main cause of the high line lightning trip-out rate. Insulator is smooth, can reduce the wire between the capacitive reactance effect, so as to reduce the loss of the current. High voltage composite insulator classification 1. Insulator is usually divided into can breakdown and not breakdown. 2. According to the structure can be divided into the column, Pillar) Insulator, suspension insulator, anti-pollution insulator and bushing. 3. According to the application is divided into line insulator and power plant and electrical insulator. Which used in the circuit can be breakdown type insulator pin type, butterfly, disc hanging, not breakdown type with cross arm and bar hanging. Used in power plant, electrical breakdown type insulator can have a hollow needle type pillars, pillars and casing, not the breakdown type pillar and the container has a bar porcelain sets. 4. Commonly used are used in overhead line insulator, pin insulator, butterfly insulator, suspension insulator, porcelain crossarm, rod insulator and taut insulator, etc. 5. Now commonly used insulator are: porcelain insulator, glass insulator, composite insulator, insulator semiconductor. ( Electric line toughened glass insulator product structure generally the main material of insulator electric line toughened glass insulators for iron cap, toughened glass, or ceramic and steel feet, and combined with cement glue glue is an integral whole. ) 【 On a message: high voltage composite insulator hydrophobic properties 】 【 The next message: measuring the equivalent composite insulator salt density solution 】
Collectively, the effect of power transmission product on industrial society has been to eliminate power distribution solutions and drastically reduce the time long associated with power distribution solutions.
Exceed customers' expectations in the procedures of manufacturing power transmission product.
In a nutshell, is actually an ultimate solution for power distribution solutions and underestimating its value cost you higher than anything else. So grab it before you miss the boat.
The above are only part of the examples regarding power transmission product, for more information, please click here Mings Electricity Technology.
