With the rapid development of new energy, China has become the largest country of hydropower, wind power, solar power generation, and renewable energy accounts for continuous increases. To make these volatility, intermittent clean electric energy, upgrade the power transmission technology is impe...

Power Fuse is a generally accepted means to protect power transformers in distribution substations. The main purpose of the Power fuse is to provide a permanent fault interruption. Fuse is an economical alternative to circuit switcher or circuit breaker protection. Fuse Fuse protection is usually...

A fuse is an insurance policy that burns wires to prevent too much electricity. In fact, the fuse is a kind of easy to burn fine alloy wire, it can only pass through the normal electric current, when the electrical flow exceeds a certain value, it will heat and fuse and cut off the power supply, ...

With regard to the product safety of the device and the life/reliability of the fuse, the right choice is important. Safety principles are considered only when properly selected and used in an agreed manner the determination function of the fuse chain can be used as a protective part. “Any ...

Fuse, installed in the circuit equipment, to ensure the safe operation of circuit components, the use of high resistivity, low melting point of silver copper alloy made, in the circuit work, the external working environment temperature, the internal pulse current and so on will affect the service...

1. Normal operating current. 2. The voltage applied to the fuse. 3. The current that needs to be disconnected from the fuse. 4. Minimum and maximum time allowed for abnormal currents to exist. 5. Ambient temperature of the fuse. 6. Pulse, Impact Current, inrush current, start current and circuit ...

First, the appearance of the inspection, fuse holder after a period of use, there may be some problems, so when used, to often check it, for its appearance should be checked first. Second, the function of the inspection. In order to ensure that the fuse holder has a good use effect, some of its f...

1) The ambient temperature rise of more than 25 ℃ will reduce the current speed through the recoverable fuse. 2) when the ambient temperature 25 ℃ by the current 100% can restore the fuse online, but if more than twice times the rated current, can restore the fuse will move. 3) The higher the amb...

Common miniature fuses are, for example, glass tubular fuses and flake fuses in cars. As a protective element of electronic equipment, glass tubular fuses are used for a long time, but because of its large size, easy to break, can not achieve automatic installation and other shortcomings, so the ...

There are many types of lightning arresters, including metal oxide arresters, line metal oxide arresters, gapless line metal oxide arresters, fully insulated composite jacket metal oxide arresters, and removable arresters. The main types of arresters are tubular arresters, valve arresters and zin...

1. The current capacity of the zinc oxide arrester is large This is mainly reflected in the ability of lightning arresters to absorb various lightning overvoltages, power frequency transient overvoltages, and operating overvoltages. The current flow capacity of the zinc oxide arrester produced by...
