The specific contents include eliminating the shortcomings found in the patrol inspection, cleaning the porcelain waterproof casing, removing and replacing the cracked or brittle leather pad, checking and tightening the nodes, replenishing the oil with less oil, checking and replacing the silica gel of the breathing mask,Products Show etc.

dAnkangThe key cause of oil leakage is sand holes and cracks in cast iron parts. For crack leakage drilling stop hole is a good way to remove in-situ stress and prevent widening.

The transformer manufacturer said that the temperature display equipment: the temperature change value is measured according to the PT temperature sensor embedded in the bottom voltage winding to immediately indicate the winding temperature of each phase (three-phase safety inspection and Zui large value indication,Santiago de veraguasCharacteristics of dry type distribution transformertrustworthy and the historical time Zui high temperature can be recorded). The Zui high temperature can be input and output as mA analog quantity. If it is to be transmitted to a distance (the distance can reach m, the electronic computer can be equipped with an electronic computer socket, an intelligent transmitter, and transformers can be detected. The over temperature alarm and trip of the system software can also be signaled by the resistor data of Pt thermistor sensor, so as to further improve the stability of the temperature maintenance system software.

XColfitzThe common dry-type transformer is an important electrical equipment, and the voltage is constantly regulated. However, the dry-type transformer will also boost voltage, and the whole process of boosting voltage is very complex, and there are many principles.

KtPower saving analysis of transformers has always been based on whether the utilization rate of transformer capacity is less than a certain standard value. Whether transformers are environmental protection and energy saving specifications. In fact,Products Show sometimes such specifications are not saving electromagnetic energy, but consuming electromagnetic energy.

The cycle time of power-off cleaning and inspection shall be determined according to the surrounding environment and load conditions, generally from half a year to once a year;

Dry type transformer, a static electrical equipment is used to change the AC current (current) of a certain standard value into another or several types of working voltage (current) with the same frequency and different standard values. According to the supervision sampling inspection data released by AQSIQ in the third quarter of last year, among the kinds of dry-type transformer commodities produced and manufactured by companies in provinces and municipal districts across the country kinds of commodities were found to be inconsistent with the provisions of relevant specifications, and the distance shall not be less than m; At the angle with actual operation, a spacing of more than m shall be reserved; If metal fence is selected, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.

UAfter the power transformer has been used for a long time, common faults of iron core will occur. Dont worry. Contact the transformer manufacturer, and the manufacturer will assign professional technicians for inspection. The main reasons are as follows:

SmanufacturerThe cycle time of power-off cleaning and inspection shall be determined according to the surrounding environment and load conditions,Products Show generally from half a year to once a year;

uTFor oil transformer oil replenishment, unused transformer oil conforming to the new standard should be selected first. In addition,Santiago de veraguasCharacteristics of dry type distribution transformertrustworthy the oil with the same basic, same brand and same additive type is expected to have a stronger effect. The characteristics of the oil should not be lower than that of the oil in mechanical equipment. When the new remaining oil is less than %, there is generally no problem. However, if there is more new remaining oil, oil shall be added before oil type Chromatographic analysis and pressure test shall be carried out to establish that there is no oil stain, the overall level of Chinas transformer industry at this stage is basically international, and the quality level is no different from that of overseas goods& rdquo; The person in charge of the transformer Federation of China Household Appliance Industry Association said.

Many people probably dont know much about the power distribution transformer manufacturers. In fact, the transformer can be plugged in for trial operation after careful inspection before capital investment. During the trial operation period,Power transformer price: 1000KVA, 33kV, 25kV, power transformer, oil immersed transformer, dry-type transformer factory you must pay attention to the following points. Whether there is abnormal sound, noise and vibration, whether there is abnormal smell such as coke smell, and whether there is discoloration caused by partial overheating. Ventilation is good. In addition, we should also pay attention to the following aspects.

productionmAccording to the introduction of transformer manufacturers, the capacity utilization rate is only about %, which is regarded as & ldquo; Great Lars car & rdquo;, After replacing one kva small transformer, the utilization rate is close, but the main parameters of the two transformers are evaluated as shown in Table . Table evaluates the main parameters of the transformer: capacity (VA) iron loss (W) copper loss (W). Firstly, the output power is saved according to the customary calculation method (ignoring copper loss): the results show that the loss of large capacity transformer is lower than that of small capacity transformer, It actually consumes electromagnetic energy.

NThe capacity and working voltage are different. The dry-type transformer is generally suitable for distribution equipment. The capacity is generally below kVA and the working voltage is below KV, which also ensures the rated voltage of kV; Oil immersed transformers are generally suitable for distribution equipment.
