10000kVA/33kV Electrical Comprehensive Transformer Test Bench
System Introduction
The whole test system adopts a combination of computer and PLC control methods. PLC is mainly used to set the logical relationship among various components, integrate and execute the underlying operation commands, and realize the basic protection functions of the system. It has flexible programming, high reliability, high-speed operation and other advantages, while the industrial control computer is mainly used for the organization of the test flow, the release of the action instructions, the realization of the system advanced protection functions, etc., Its communication with the PLC through RS-485 and completely isolated can effectively prevent the communication signal from being disturbed and ensure the safety of the computer when the test product fails to discharge to ground;
The test system adopts the way of frequency converter to realize the multi-speed adjustment of the speed of the lifting and lowering speeds in the performance test to achieve finer voltage and current adjustment levels and more accurate data sampling capabilities.

Delivery time and other
Delivery date is 50 days, The delivery date shall be calculated from the date of payment.
Quality assurance
The supplier implements the product's lifetime warranty policy, one year's free warranty period in foreign countries, and the free warranty period starts at the date when the purchaser checks and accepts the complete set of equipment.
Precautions
1. The equipment demander only needs to provide three : power distribution cabinet with frequency 50Hz±0.1 and current not less than 500A;
2 The grounding resistance of the installation site shall not be greater than 0.5 ohms; in order to maintain the integrity of the site, it is better to pre-ditch the cable trench in the control room and equipment area during the civil construction;
3. Delivering the equipment should also provide detailed technical documents, instructions for use, electrical installation plans and related information;
4. The unfinished matters are negotiated and resolved by the two parties.
