Xu Ji Electric

business background

XJ Electric is the vanguard of the national power system automation and power system relay protection and control industry . It is known as the enterprise with the strongest supporting capacity in China's power equipment industry. It is a national key high-tech enterprise recognized by the Ministry of Science and Technology , and a national 520 key As one of the enterprises and national major technical equipment localization bases, it has undertaken a series of major research projects during the period from the " Sixth Five- Year Plan " to the " Eleventh Five-Year Plan" . Most of the products have won national, provincial and ministerial scientific and technological progress awards. Based on XJ Electric's development of a new low-voltage circuit breaker with Bluetooth function, Zhongneng Wulian has the development experience and location advantages of Bluetooth modules, so XJ Electric evaluates whether Zhongneng has the ability to cooperate in terms of solution providers and factory selection.


Why choose Zhongneng IoT

Zhongneng Wulian has independent development capabilities in Bluetooth modules, and is supported by multiple original manufacturers. Original factories such as Telink, Furuikun, Fengjiawei, and Jieli directly support Zhongneng Wulian.

Taking into account the need for independent development capabilities to provide technical support at any time, Xu relay has its own production plant and considering the cost of distance, it finally chose Zhongneng Wulian and Xuji to develop Bluetooth low-voltage circuit breakers.



The XJ hardware solution adopts the ZD-FrB3 module for docking, and the XJ low-voltage circuit breaker is connected with the ZD-FrB3 through the communication interface, and performs data interactive communication with the Bluetooth module.

Authorize the operation terminal to operate the low-voltage circuit breaker through the administrator APP, then the operation terminal can perform parameter setting, maintenance, inspection, etc. on the low-voltage circuit breaker.
