New energy intelligent booster transformer (American style)

SMART GRID

New energy intelligent booster transformer (American style)

Product Introduction

ZGS-40.5/0.4~1.14KV new energy intelligent step-up transformer (American style) is a product specially designed and developed by our company for the photovoltaic and wind power generation fields. The photovoltaic inverter export voltage is 0.4~0.8kV, and the wind turbine export voltage is 0.69~1.14KV. It is stepped up to 35kV by the combined transformer and then transmitted to the 35/110kV step-up station by the 35kV cable line to realize power generation and grid connection.

With 24-way rumor message input;

With 4-way DC input, it can collect transformer oil temperature and ambient temperature inside the box transformer;

With AC sampling function, it can measure remote measurements such as 1, U, P, O, F, COSФ, active energy, reactive energy, etc.

It has non-electrical protection functions, including: heavy gas, light gas, transformer oil level, oil temperature, etc.;

The following switch states can be collected: 35kV load switch position signal, low voltage side circuit breaker position signal, high and low voltage near and remote control switching signal, circuit breaker position signal, fuse blown signal, circuit breaker trip signal, box-type substation door open/close signal, etc.;

Remote control function: remotely control the opening and closing of switches with electric control function

It has perfect event report processing function and operation record function, and can save at least the latest 25 SOE change records and the latest 25 user operation records;

With communication function, the device communication protocol adopts the standard IEC 103/104 protocol, which can be easily connected to the integrated automation system of various manufacturers, and the communication protocol will eventually match the integrated automation manufacturer's protocol;

All components including power supply, CPU, I0 board and communication board meet the wide temperature range of -40℃~+70℃ and the device can ensure normal operation to meet the special environment of wind farms.
