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.  

The circular through core current transformer is mainly used in the  cable circuit environment, which has simple structure, small volume and flexible application. According to the cable specifications used in the main circuit, there are many kinds of hole diameter corresponding to the core penetration. The diameter of the pierce hole of this series of product is from 25mm to 200mm, and the current of the main circuit includes 63A ~ 2000A. The series of products can meet the technical requirements of different precision such as 0.2, 0.5 and 1. At the same time, it can also meet the strict requirements of the new national standard for the balance characteristics. The unbalanced current output value can also be better than 30mA, 10mA, 5mA, even 3mA, which greatly reduces the false alarm caused by the interference of the current and magnetic field of the main circuit, and provides sufficient guarantee for the reliability of the equipment. Excellent and advanced production process. This series of products meet the requirements of GB-14287.2-2005 and GB14287.2-2014.

The product is perforated input single-channel DC leakage current isolated transmitter. The measured DC current signal is isolated by a high-precision isolation device, and the output is linear 0~5V,0~10V, 0~20mA,4~20mA and other standard signals. It is widely used in power supply equipment, power grid monitoring, industrial control monitoring system, railway signal system and other industries.

Open-close outdoor waterproof transformer, the biggest feature of this series of transformers is the waterproof function, which can be used outdoors. Its section port is surrounded by rubber pads to prevent rain from entering. Of course, most so-called waterproof transformers on the market use rubber pads as a means, but there are also limitations in using this means for waterproofing. Because it is impossible to guarantee the water proof of the transformer itself ,our company adopts the technology of transformer forming once, that is, the transformer is directly made into a solid in the mold, and the plastic is wrapped around the whole body without any gap. Meanwhile, waterproof terminals and sheath lines are used in the secondary side leads to ensure that no rain can enter the transformer body. Our company transformer waterproof grade has reached IP67/IP65. This product meets part of the standard GB20840.1.2 . 

This product is the electronic core and shell assembly into one, easy for users to produce and assemble, accelerate the production schedule.
