The visual inspection method is that the staff use human eyes to observe the appearance change of the visible parts of the operating equipment to find out the abnormal conditions of the equipment, such as discoloration, deformation, offset, cracking, loosening,power transformer price 1000kva ignition and smoke,BlanickTransformer temperature in high voltage distribution roomTalking about the working organization oil leakage and oil leakage, short-circuit fault marks, hanging of dirty things, etching and turbidity, etc. can be checked according to the visual inspection method. Therefore, visual inspection is one of the common methods of equipment inspection.

8Transformer manufacturers generally adopt IP protective casing, which can avoid the entry of solid dirt with a diameter of more than mm rats, snakes cats, birds and other animals,power transformer price 1000kva resulting in vicious common faults such as short-circuit fault and power failure, and provide a safe natural barrier for the energized part. If the transformer equipment must be outdoors, IP protective casing can be adopted, which can avoid being equally divided with the above IP protective effects However, IP casing will reduce the refrigeration capacity of the transformer, so pay attention to the reduction of its operating volume.

bUherskibrodPlug in the power with full load first, check whether the equipment has abnormal sound, ignition, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.

The insulation between silicon steel sheets is damaged,power transformer price 1000kva resulting in overheating and melting of the iron core;

BRubeDry type transformer, a static electrical equipment,BlanickTransformer temperature in high voltage distribution roomTalking about the working organization 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 with a compliance rate of %& ldquo; This result mostly shows the quality level of Chinas dry-type transformer industry at the present stage.

FdMany 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, you must pay attention to the following points. Whether there is abnormal sound, noise and vibration, and whether there is discoloration caused by partial overheating. Ventilation is good. In addition, we should also pay attention to the following aspects.

Dry type transformer,Power transformer price: 1000KVA, 33kV power transformer, 25kV power transformer, power transformer, oil immersed transformer, dry-type transformer factory 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, with a compliance rate of %& ldquo; This result mostly shows the quality level of Chinas dry-type transformer industry at the present stage.

The appropriate power saving calculation formula should be derived from the following process: active power loss of large capacity transformer: load of large capacity transformer; PDK - short-circuit fault loss of large capacity transformer, kW. Active power loss of small capacity transformer: when a pump room is in normal operation, two pumps are started separately, and each pump is driven by kW motor, so the usual load is KW, CST = . One kva transformer was originally configured

wThe vibration reduction of the grounding device sheet solves the problem of modifying the fixed hard connection between the copper sheet of the grounding device and the dry-type transformer. The original oscillation of the dry-type transformer will be transmitted to the metal in the concrete by the baffle and cause low-frequency noise. Therefore, it must also be changed to produce flexible connection.

CWhen the output power P of the transformer is equivalent to the input power P, the efficiency & ETA; Equivalent, the transformer will not cause loss. But in fact, there is no such transformer. Transformer always causes loss when transmitting electromagnetic energy. The key of this kind of loss is copper loss and iron loss. Copper loss refers to the loss caused by the number of turns of transformer coil. When the current has a fever according to the number of turns of the coil, part of the electromagnetic energy changes into energy and is lost. Because the electromagnetic coil is generally wound by copper core wire with insulating layer, it is called copper loss.

nZThe visual inspection method is that the staff use human eyes to observe the appearance change of the visible parts of the operating equipment to find out the abnormal conditions of the equipment, such as discoloration, deformation, offset, cracking, loosening, ignition and smoke, oil leakage and oil leakage, broken strand disconnection, short-circuit fault marks hanging of dirty things, etching and turbidity, etc. can be checked according to the visual inspection method. Therefore, visual inspection is one of the common methods of equipment inspection.

In order to better avoid transmission overvoltage damage, a group of overvoltage maintenance high-voltage Arresters (such as ycs active zinc oxide high-voltage arresters) shall be refitted at the working voltage bus duct side of dry-type transformer.

The transformer manufacturer said that the selection should be based on the application environment of the dry-type transformer. For the extremely extreme environment, the dry-type transformer should be poured with epoxy resin glue. Because this kind of environment does not need to heat the dry-type transformer, it can operate immediately. However, for the general application environment, the class H dry-type transformer can be used.

MPlug in the power with full load first, observe and detect that the input and output voltage meets the regulations. At the same time, check whether the equipment has abnormal sound, ignition, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.

qUherskibrodIf the input of dry-type transformer is an alternating switching power supply, its output voltage is directly proportional to the coil turn ratio of the output input solenoid coil. If a rechargeable battery is used, add a circuit in the input power supply circuit to change it into a continuously changing voltage. In that way, the alternating DC current can be obtained at the output end.

vSThe insulation of the through core anchor bolt clamping the iron core is damaged, resulting in a short circuit fault between the silicon steel sheet of the iron core and the through core anchor bolt;

When the output power P of the transformer is equivalent to the input power P, the efficiency & ETA; Equivalent, the transformer will not cause loss. But in fact, part of the electromagnetic energy changes into energy and is lost. Because the electromagnetic coil is generally wound by copper core wire with insulating layer, it is called copper loss.
