fault locator

,

underground electrical fault locator

This kind of device is applied to the overhead power distribution network automatic system from 6KV to 35KV,is used to improve the safe and reliable operating performance through centralized monitoring the current, temperature and fault condition on the power distribution circuit.

Data Terminal Unit:

It is composed of singlechip system, GPRS/GSM module, radio frequency communication module and solar energy supply unit. This device is installed on the pole 100m at most away from the indicators, is fixed by hoop directly. The function of DTU is to receive the signal from the detecting terminals(communicable indicators) and send the signals to the main station through GPRS/GSM. The size is height*width*height=300*200*120mm.

Each Data Terminal Unit can equip with many sets of 

communicable FCI within 100m.

This device is taking electricity from solar panel. In the daylight, the solar panel supply enough electricity for the device, and also, incharging to the storage battery at meantime. When in the night and cloudy day, it is powered by storage battery.

The Solar power supply is a device which makes use of a number of linked light-sensitive battery pack to turn the solar energy into electricity energy directly. Solar energy battery pack is a solid device which makes use of electronics characteristics of semiconductor materials to realize P-V transformation. It is a component which responses to light and can turn light energy into electric energy, adapts a kind of material named polycrystalline silicon which can generate photovoltaic high efficiency, its generating power principle is that type P of crystalline silicon is mixed with phosphorus then get Type N of crystalline silicon and form P-N combination. When the sun shines the solar panel, part of the photon is absorbed by the silicon, the energy of photon will be transmitted to silicon atom, which makes the electrons move and become to free electrons gathering both sides of P-N combination and form potential difference, then directly link to the storage battery in the Data Detecting Terminal and charging to the storage battery.

The device adopts 433M or 2.4G module which can receive and send in the meantime, is composed of wholly-integrated frequency modulator, a receiver with demodulation, a crystal oscillator and a regulator.
