Villa NicholasWhen the new oil filled by the power transformer and the oil sample that has just been considered are used, the oil sample can be used only after sufficient standing.
The insulating layer in the middle of the silicon steel plate is aging, the anchor bolt cover with the iron core is damaged, resulting in heat, temperature rise, and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.

(5) the installation position of secondary commercial insurance of transformer on column and ground shall meet the following requirements: if there is an disconnector on the secondary side, it shall be installed between the disconnector and low-voltage composite insulator, or the circuit breaker shall be selected as the disconnector; If there is no disconnector on the secondary side,Villa Elisa Price of dry-type transformer 2500, it shall be installed on both sides of the low-voltage composite insulator, and between the electromagnetic coil and the tap changer.
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?
Power transformer
During no-load test run between the electromagnetic coil and the group outlet pipe, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.

When we apply oil immersed transformer, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?
OK or not?.Power transformer
Loose core screw
(III) dry type transformers of 315KVA and below can be installed on poles. The distance between its bottom end and the road surface shall not be less than 5m; The distance between the electrified part and the road surface shall not be less than 5m.
The electromagnetic coil is wound with copper power wire or foil and lifted with glass fiber. The epoxy adhesive does not need filling. The vacuum drying equipment is used for degassing and dehumidification. The overall concrete is poured with high fracture toughness,Villa Elisa Price of 500 KVA box type transformer, resistance to short-circuit faults, common faults and impact. The work is diligent.
average method.Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin,Villa Elisa Power station transformer, 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.
The transformer manufacturer shall not use hand touch method to detect energized high-voltage equipment, such as transformer in operation and neutral grounding equipment of arc suppression coil. For the equipment without power supply and whose shell is reliable grounding device, the temperature or temperature rise must be tested by hand. The secondary equipment can be inspected by hand touch method when it is hot and vibrated.

There are also many problems to pay attention to in the preventive measures and process of dry-type transformer damping. What are the key effects and functions of dry-type transformer damping and the corresponding preventive measures? Let's master and consult in detail with the small editor of the dry-type transformer manufacturer.
