T-Breaker Electric 2400V/30kA High Voltage DC Protection Device Test System Launched
Recently, Hangzhou T-Breaker Electric Co., Ltd. has completed all the research and development work of the "2400V/30kA high-voltage DC protection device test system". The new system has been put into operation in Hangzhou T-Breaker Testing Technology Co., Ltd. and officially undertook the third-party inspection and testing business.
Brief Introduction of 2400V/30kA High Voltage DC Protection Device Test System
The high-voltage DC protection device test system adopts large-capacity, ultra-high-power hybrid energy storage technology, and can output up to 72MW of instantaneous pulse power. The independently developed large-capacity IGBT solid-state switch can achieve high-frequency on-off control of DC current within 2400V, 30kA, and the timing control accuracy reaches one ten-thousandth of a second. Compared with traditional test solutions, this test system has the characteristics of large test capacity, small footprint, and long life, and it is free from dependence on large-capacity power grids. It is more suitable for configuration and use in corporate laboratories such as device manufacturers and system integrators. The types of devices that can be tested by the system include but are not limited to DC contactors, DC relays, DC fuses, smart fuses, DC circuit breakers, etc. The main test capabilities are as follows:
Test products | Test items | Test parameters |
DC contactor DC relay | On and off life | Voltage: DC2400V Current: 1000A On and off time: selectable |
Maximum breaking capacity | Voltage: DC2400V Current: 10kA On/off time: selectable | |
Short circuit resistance/short circuit resistance matching | Voltage: DC2400V Current: 30kA Power-on time: 0~50ms (precisely controllable) | |
DC fuse | Breaking capacity test | Voltage: DC2400V Expected short-circuit current: maximum 30kA Time constant: maximum 10ms |
Overload breaking capacity | Voltage: DC2400V Overload current: 2le~10le | |
DC relay | Breaking capacity test | Voltage: DC2400V Expected short-circuit current: maximum 30kA Loop inductance: minimum 10uH |
High voltage, high current, low loop inductance
The system can provide load conditions of DC2400V and 30kA, and the minimum inductance can be less than 8uH.
Innovative technology route, multiple safety protections
The use of solid-state switches as protection switches greatly improves the service life and protection speed of the system protection switch. In addition, this system abandons the traditional power grid power supply technology route and adopts hybrid energy storage technology based on supercapacitors. It has no special requirements for grid capacity and does not require dedicated lines. There is no impact on the grid during the test, which provides multiple safety protections for the test system, making the test more convenient and simpler.
A major breakthrough in the new energy industry
