When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.
Dillin.Transformer inspection nose sniffing method
The switching power supply lacks one phase of power;
.The technical specification of power consumption requires that the resistance of maintenance grounding wire shall be ≤ 4Ω, The resistor is generally more than 2000 & omega;,DillinBox type transformer 160KVA price, According to Ohm's law when the insulating layer is damaged, the current is only 1 / 500 of the total current flow, so as to play a guarantee effect. The higher the voltage, the smaller the resistance, in other words in the case of high voltage. We can care about the power transformer plant and master a lot of professional knowledge.
Generally speaking, the ignition emergency treatment method of oil immersed transformer is mainly to disconnect the oil immersed transformer, disconnect the switching power supply on each side, quickly invest the reserved oil immersed transformer and start the power supply system from scratch. Stop the operation of refrigeration equipment. Key oil immersed transformer ignition. When L-type oil immersed transformer and high voltage station oil immersed transformer are ignited, which can control the oscillation below 0.2%, and then reduce the building structure noise transmitted by dry-type transformer oscillation.

Installation conditions.Deterioration damage of transformer core insulation
The time difference between different steps of three-phase power switch of switching power supply shall be less than 10ms, the closing shall be maintained by high-voltage arrester, and the neutral line of transformer shall be reliably grounded (it shall be grounded immediately).
The cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of 2-5A / Min2.
Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin, cooled by natural air and large capacity by centrifugal fan. Oil immersed transformers are insulated by insulating oil, insulated by insulating oil in the circulating system inside the transformer,DillinOil immersed self cooling transformer, and heat is discharged on the radiator (radiator) of the circulating system inside the transformer.
How many?.Difference between dry-type transformer and oil immersed transformer:
The transformer manufacturer said that the temperature display equipment: the temperature change value is measured according to the PT100 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, and the historical time Zui high temperature can be recorded). The Zui high temperature can be input and output as 420mA analog quantity. If it is to be far away (the distance can reach 1200m, the electronic computer can be equipped with an electronic computer socket, an intelligent transmitter, and 31 transformers can be detected. The over temperature alarm and trip of the system software can also be signaled by the resistor data of Pt100 thermistor sensor,DillinDistribution rectifier transformer, it can be in a power transformer such as a glass test tube when it is not in operation to extract the oil sample at the bottom, or it can be replaced by changing the oil.
Dillin.Operation and maintenance management of oil immersed transformer
Oil leakage of bolt or pipe external thread
For example, in the 1970s, the radio programs applied by every family in the countryside had a ground wire, and they were often wet with tap water. Protective grounding is to bury the copper plate of metal electrical conductor in the soil layer, and then lead a point of it out of the road with transmission line, which completes the grounding protection. The grounding wire specifies the grounding wire resistance ≤ 4Ω. Grounding protection is a safeguard measure adopted to avoid safety accidents when using household appliances, office and other electrical equipment.
