Protection devices

Guodian Xu Zhen protection devices - generator over-current protection device GDB-1 application in small and medium sized power plant generator protection system to replace the traditional relay-type protection device, delay control to PIC microcontroller core on generator over current protection, over voltage protection, under-voltage protection High accuracy, stability, good reliability. In the generator power system, the traditional relay-type protection device, there is no high precision, poor stability, reliability, tuning trouble, cumbersome to install shortcomings. Xu Zhen Shenzhen State Power Electric successfully developed the industry's leading generator over-current protection device, with its high integration, high stability, high reliability, high cost of enormous advantage in generators, transformers, circuit protection technology field has broad influence and market share! Product details: 1, high accuracy, good stability and reliability. 2, centralized control, wiring is simple, easy to install. 3, to replace the traditional multiple relay protection mode. 4, with overcurrent, overvoltage, undervoltage protection. 5, the protection of the current inverse time control. 6. All the parameters are password protected, to prevent arbitrary changes. 7, fault indicator, buzzer alarm, digital display three-dimensional fault diagnosis. Technical indicators 1.
