With the emergence of our country's Industry 4.0 , our requirements for the inspection and maintenance of various high- power power equipment such as aviation ships, power plants, and new energy vehicles are getting higher and higher. How to choose the right and economical load box and other testing equipment has become a common concern for everyone .
Next, we will introduce how to choose a suitable load bank from three aspects:
1. Selection of resistance materials
The performance and parameters of the load bank are greatly affected by the resistive material. Therefore, the choice of materials with different properties for different applications is different. The load bank is designed with resistors and high-quality resistance materials independently developed and produced to give full play to the excellent performance of various materials. The overall matching degree of the load bank is good, which can greatly optimize the structure and performance, and realize the reliability and long life cycle of the product.
2. Influence of load bank inductance on working environment
The load bank can be divided into pure resistive load, inductive load and capacitive load; it can also be divided into resistance sensing integration, resistance capacitance integration and resistance sensing capacitance integration. Pure resistive load can be divided into pure resistive non-inductive load and pure resistive inductive load, but inductive load and non-inductive load are relative, the inductance made by non-inductive load will be less, so there is no pure non-inductive load . Control the allowable inductance value of the high-power load bank at different power operating frequencies.
3. How to choose the overcurrent protection function of the load bank?
1 ) When the circuit fails, the current may suddenly increase. When the fault current in the line exceeds the action value of the relay / thermal relay, the relay action selectively cuts off the fault line according to the requirements of the protection device.
2 ) When the circuit fails, the current may suddenly increase. When the fault current in the circuit exceeds the upper limit of the current fuse, the resistance fuse will automatically blow, thereby cutting off the load.
Of course, in addition to choosing a load bank with a suitable purchase price, the current load bank rental and testing business is also very popular. The load bank leasing business has certain advantages, saving the purchase cost of the load bank and avoiding the annual fixed maintenance of the load bank. At the same time, the rental service provided by load bank manufacturers is more professional and convenient!
