BaktapurScb13 In relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word,ValentariQuotation of 315 KVA oil type transformer, if there is any problem at a certain point, it will affect the whole power circuit
After sampling, bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.
Valentari.With Vietnam and Malaysia, China's first UHV transmission experimental demonstration project,ValentariRecovery price of oil transformer, China Transformer Corporation has entered a breakthrough in the development trend. The commodity voltage grade and volume rank first in the world occupying the main technical position of the industry development trend. In addition, it has promoted the continuous improvement and perfection of the technology of low-voltage transformers.
Therefore,ValentariApplication scope of oil immersed transformer, in the operation prevention and regulation of relay protection dry-type transformer, it is necessary to find the short-circuit fault point according to the fault situation, lock the fault point, and analyze the short-circuit fault types of relay protection dry-type transformer. At the same time, if all fields are clear, disconnect the switching power supply at the fault point, the maintenance work of employees will be carried out smoothly, and the harm will not expand to a greater extent.
.Due to poor sealing, generally, the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well, it will lead to common faults of oil leakage.
Turn off the gate valve (butterfly valve) of the left and right tablet computers of the heat pipe radiator to isolate the oil in the heat pipe radiator from the oil in the tank, so as to reduce the working pressure and leakage. After the leakage location is determined, appropriate surface treatment shall be carried out, and then Fushi blue raw materials shall be selected for sealing treatment.
Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;
The capacity and working voltage are different. The dry-type transformer is generally suitable for distribution equipment. The capacity is generally below 2000kVA and the working voltage is below 35KV, which also ensures the rated voltage of 110kV; Oil immersed transformers are generally suitable for distribution equipment.
The transformer manufacturer shall not use hand touch method to detect energized high-voltage equipment, such as transformer in operation and neutral grounding equipment of arc suppression coil. For the equipment without power supply and whose shell is reliable grounding device the temperature or temperature rise must be tested by hand. The secondary equipment can be inspected by hand touch method when it is hot and vibrated.
Before no-load impulse closing, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.
production costs.Power transformer plant
In the whole process of transmitting electromagnetic energy in the power supply system, it will inevitably cause the loss of voltage and output power. When transporting the same output power, the voltage loss is inversely proportional to the voltage, and the output power loss is inversely proportional to the square meter of voltage. The transformer is used to increase the voltage and reduce the closing damage.
