Do you know what conditions are required for the parallel operation of transformers?
The parallel operation of transformers means that the primary windings of two or more transformers are connected in parallel on the busbar of the same voltage, and the secondary windings are connected in parallel on the busbar of another voltage.Its meaning is: when one transformer fails, other transformers running in parallel can still continue to operate to ensure the power consumption of important users; or when the transformer needs to be repaired, the standby transformer can be connected in parallel, and then the transformer to be repaired is powered off and repaired. , which can not only ensure the planned maintenance of the transformer, but also ensure that the power supply is not interrupted and improve the reliability of the power supply.
How to judge and deal with these abnormal phenomena in transformers?
1. Analysis of abnormal operation of transformers(1) The sound of the transformer is abnormalAs soon as the transformer is connected to the power supply, there will be a buzzing sound, which is mainly due to the effect of high-voltage magnetic flux. During normal operation, the sound of the transformer is uniform. When there are other noises, you should carefully find the cause and deal with it.
Transformer No-load/Load Test Introduction
No-load test: Apply the rated voltage of the sine wave rated frequency from a certain winding of the transformer (generally from the secondary low-voltage side), and open the other windings to measure the no-load current and no-load loss. If the test conditions are limited and the power supply voltage cannot reach the rated voltage, the test can be performed under non-rated voltage conditions. This test method has a large error and is generally only used to check whether the transformer is faulty. Only the test voltage reaches more than 80% of the rated voltage. can be used to test the no-load loss.
From classification to wiring mode, the most comprehensive explanation of grounding transformer
The grounding transformer is referred to as grounding transformer for short. According to the filling medium, the grounding transformer can be divided into oil type and dry type; According to the number of phases, the grounding transformer can be divided into three-phase grounding transformer and single-phase grounding transformer. The function of the grounding transformer is to provide an artificial neutral point for the system with ungrounded neutral point, which is convenient for the use of arc suppression coil or small resistance grounding mode, so as to reduce the capacitance current to ground in case of grounding short circuit fault in the distribution network and improve the power supply reliability of the distribution system.
When does magnetizing inrush current occur in transformers?
01 Inrush currentWhen a transformer is first energized, a phenomenon called magnetizing inrush occurs. Although inrush currents are generally not as disruptive as fault currents, the duration of magnetizing inrush currents is on the order of seconds (compared to periods with fault currents).
The principle, structure and operation and maintenance of transformer gas protection
Gas protection is the main protection for transformer internal faults. It can act sensitively to transformer inter-turn and inter-layer short circuits, iron core faults, internal bushing faults, internal winding disconnection, insulation deterioration and oil level drop. When a fault occurs inside the oil-immersed transformer, the arc will decompose the insulating material and generate a large amount of gas, which flows from the oil tank to the oil pillow, and its intensity varies with the severity of the fault, reflecting the air flow and oil flow The action protection is called gas protection, also called gas protection. During the operation of the transformer, due to internal faults, sometimes we cannot identify and take measures in time, which is easy to cause some accidents. After the protection of the gas relay, the occurrence of similar incidents can be avoided to a certain extent.
About transformers, you have to master the knowledge points!
1. What is a transformer?In the AC circuit, the device that increases or decreases the voltage is called a transformer. The transformer can convert any value of voltage into the voltage value we need with the same frequency to meet the requirements of electric energy transmission, distribution and use.For example, the electricity from a power plant has a low voltage level, and the voltage must be increased before it can be transported to a distant power consumption area. The power consumption area must be reduced to a suitable voltage level to supply power equipment and daily electricity. Equipment.
The harm of transformer oil seepage and its treatment methods
1. The oil leakage of the transformer will not only seriously affect the appearance, but also cause economic losses because the transformer needs to be shut down to eliminate leakage. If there are many oil stains on the ground foundation of the transformer, it may also become a fire hazard.
How much KW power consumption can a 1000KVA transformer withstand?
Question:"There is an old-fashioned transformer of 1000KVA with an existing load of about 200KW. If a new load of about 600KW is to be added, can this transformer withstand it?"
