Overview
At present more and more falling type fuses are employed in rural power grid and outlying suburbs. Because the equipment has no effective monitoring means, the electric emergency workers could not get to the scene in time to deal with the accident in the case of a fusing and falling accident. Because of failed to repair in time, this will cause economic loss and reputation damage to the power company, this may even lead to social instability.
On-line detection equipment has been extensively used in power distribution network with the development of China’s power grid. The online monitor for falling type fuse developed by our company uses gravity induction technique, high voltage energy extraction technology, a wireless communication technique, information networks, electronic technique and other modern technologies. This monitor can quickly and accurately on-line detect the state of falling type fuse, meanwhile, the monitor will send the collected fault information to the monitoring center or operation and maintenance staff. The operation and maintenance staff can take the corresponding type of fuse to the accident site to repair immediately after receiving this information. This can shorten the power outage time. The monitor provides great convenience for trouble locating.
Characters of the online monitor for falling type fuse
Hardware adopts modular design and easy to maintain.
Utilize wide temperature components, adapt to outdoor harsh working environment.
The CT power is obtained directly from the high voltage source. This can make sure that the monitor can operate normally under rated voltage and overload. No external PT power supply is required, energy-saving and environment-friendly.
Use super-capacitor, can extend service time for 15~20 years.
Use advanced microprocessors and technique, convenient for intelligent management.
The monitor can pre-set receiving number and alarm address through the phone. The reservation of all these parameters will not disappear due to power failure.
The monitor structural design is reasonable and compact, convenient to use and install.
