Coronell220 kV TransformerAnalyze its advantages

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

Solenoid insulation deterioration

Coronell.The fundamental reason for this kind of inaccuracy is that when the transformer & ldquo; Dalar trolley & rdquo; is considered according to the size of capacity utilization rate, the high-capacity transformer must be replaced by the small-capacity transformer with high utilization rate, for a certain load the active power loss of small capacity exceeds that of large capacity The active power loss of the transformer,CoronellOil immersed transformer protection, so it consumes electromagnetic energy.

On load commissioning:

.The hanging core of dry-type transformer is a vital part

In specific daily life, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?

When the full load test is carried out and everything is normal, the load can be connected.

Dry type transformer

Power saving analysis of transformer

The scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?

build.What is the wavelength of oil immersed transformer?

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.

35kV and above & plusmn; No load of rated voltage; Part of the circuit breaker of the tap power switch is installed in the phenolic resin insulating paper cylinder, and the insulating paper cylinder is installed on the wooden frame. The actual operation rocker is connected with the dynamic circuit breaker of the tap power switch according to the wooden insulating rod. The on load tap off power switch is insulated from the ground by the insulating paper cylinder of the power switch itself and the insulating limit.

How to reduce the failure of dry-type transformer?

For more, please check.A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?

In order to better avoid overvoltage damage, 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 and heat is discharged on the radiator (radiator) of the circulating system inside the transformer.

(I) the distance between the external contour of 10kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer, and the distance shall not be less than 1m; At the angle with actual operation, a spacing of more than 2m 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.

The insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection, the oil shall be pumped into the bottom of the bell jar before the bell jar can be removed.
