AnfotaboHow much is 200 KVA oil transformerHow to construct

When the transformer is put into operation,AnfotaboPower supply transformer S11, if the tap changer is not in time, a great & ldquo; Tweet & rdquo; The high-voltage fuse is broken when the noise is serious; If the tap changer is defective, it will cause mild & ldquo; Squeak & rdquo; Corona discharge sound, once the load increases, it is likely to burn the circuit breaker of the tap changer. In case of such situation, the ratio of output power to input power of transformer is called the efficiency of transformer, i.e. & ETA; Is the efficiency of the transformer; P1 is the input power and P2 is the output power.

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.

.Before no-load impulse closing, the transformer shall be placed for 24h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.

Power transformer plant

When the power transformer operates at full load, it needs a large reactive load. This reactive load shall be provided by the power supply and distribution system. If the transformer volume is too large it will not only increase the initial project investment, but also make the transformer operate at full load or load for a long time, expand the proportion of full load loss, reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.

In the case of dry-type transformer operation, there is more noise, and some even cause noise, which seriously endangers everyone's no problem rest time and work. At this time, the dry-type transformer needs sound insulation treatment. There are many processes and key methods to deal with the noise of the common dry-type transformer. How should the noise of the dry-type transformer be solved? Or with the dry-type transformer manufacturer's network editor to simply understand it.

During the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.

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;, 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,AnfotaboOil immersed transformer manufacturer, 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.

Free consultation.Solenoid insulation deterioration

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.

If the oil immersed transformer is burned by the cover of the transformer, when the oil immersed transformer fails, open the lower side of the transformer and place an appropriate part. When the oil immersed transformer is on fire,AnfotaboOil immersed transformer, the oil cannot be released to avoid the occurrence of the oil immersed transformer. At the same time, use detection equipment to put out the fire immediately. In order not to expand the hazard, and accurately measured with a 2500V grounding megger. The insulation resistance from the primary side to the secondary side and the ground should be ^ 300mfl, the insulation resistance from the secondary side to the ground should be ^ 100mh, and the insulation resistance from the iron core to the ground should be & amp; gt; 5mfl (note that the grounding device piece should be removed).

Oil leakage of porcelain pot and laminated glass oil level gauge

Anfotabo.When using the oil sample of the power transformer in operation, it is necessary to add some oil from the oil gate valve at the lower part of the oil tank or the sampling gate valve to release about 2kg of waste liquid stored at the bottom to clean the oil inlet and then take the oil sample.
