Overhead Transmission & Power Taking Device

High precision transient recording type fault indicator, according to the applicable line can be divided into overhead line type,cable line type,according to the way to monitor the fault can be divided into external signal type, transient and steady state signal detection type, according to the indication mode is divided into local indication type and remote transmission type, these types are divided into different aspects of the fault indicator. Therefor, it can be combined as an overhead line local indication signal type fault indicator.

Transient recording fault indicator is mainly used in distribution system to monitor and locate line faults. It can record the transient current and voltage waveform when the fault occurs. When there is a fault in the line, such as a short circuit or ground fault, the fault indicator will quickly  capture the transient signal. These transient signals have a short duration, but contain the key information of the fault, such as the fault direction, fault type and so on. The fault indicator is easy to install and is generally installed on an an overhead line or cable line. Its advantage is that it can accurately locate the fault section, reducing the time and labor cost of fault finding. At the same time, through the analysis of the recorded wave data, it can also help the staff to better understand the characteristics of the fault, which is helpful to evaluate and optimize the operating state of the power grid.

The high-intensity magnetic power taking device is mainly composed of high-intensity magnetic, copper rivets, high-temperature crimping terminal and high-temperature cable. When the cable needs to be powered, the high -intensity magnetic is mutually attracted to the screw below the switch or screw above the switch. After determining the branch position of the main line, it can contact with conductor. The product has small volume, convenient construction, can be built-in temperature sensor, performance parameters can be customized.

Overhead transmission & power taking device adopts aluminum ally shell, open structure, suitable for 35KV and above voltage overhead transmission line above, through the principle of electromagnetic induction, to obtain low voltage, safe working power supply, and photovoltaic panel auxiliary for the monitoring device to provide power.  

The intelligent photovoltaic DC busbar monitoring device is applied to the intelligent photovoltaic busbar, which has the functions of monitoring the operating status of the panels in the photocell array, measuring the current of the photocell,measuring the voltage of the photocell, collecting the status of the surge protector of the busbar, collecting the status of the DC circuit breaker, and the relay contact output for driving the external actuator. The intelligent photovoltaic DC bus box monitoring device can display the real-time data and status of each circuit of the bus box, and can be connected with industrial control equipment and computers through RS485 interface to from an intelligent photovoltaic operation and maintenance measurement and control system.

The power taking device of the overhead distribution network is an open-type structure, which is installed on the overhead distribution line (6KV ~3KV) through the insulated rod. Through the principle of electromagnetic induction, the low voltage and safe working power supply is obtained, and the photovoltaic panel is assisted to provide power for the monitoring device.
