Operation and maintenance management of oil immersed transformer

Oil immersed transformer company

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

Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;

.Protective measures for damping of dry-type transformer

The clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand, the fixed finger is at 12 o'clock, low noise, fire safety and explosion-proof and high reliability. There are two key development prospects: one is the development trend of high voltage and high voltage, especially 750kV and 1100kV. The second is the development trend towards environmental protection, energy conservation and miniaturization. The former key is applied to the long-distance substation project route, and the latter key is applied to the substation project route in big cities.

The clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand, the fixed finger is at 12 o'clock, and the phasor of the phase voltage of the secondary side is used as the second hand.

market.Method and process of taking oil sample of power transformer

(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, it shall be installed on both sides of the low-voltage composite insulator, and the insulated cable jumper shall be connected to the insulated cable on both sides of the circuit breaker.

It will also produce many faults, effectively deal with various faults of oil immersed transformer, and continuously improve the safety factor of oil immersed transformer. Ignition is a common fault of oil immersed transformer. The key fault of oil immersed transformer is short-circuit fault, and short-circuit fault is more general.

The oil in the machinery and equipment of the oil storage tank shall generally stand for more than 8h before sampling; it is not necessary to stand when sampling on the running power transformer.

device management.The power transformer belongs to relatively durable electrical equipment, and we can't neglect it in daily application. The common problems of power transformer conductor,BacalitaHow to select power transformer, power transformer winding and power transformer tapping power switch are analyzed below:

Transformer inspection ear

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.

Bacalita.Avoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core,BacalitaDistribution transformer ranking, and long-term scalding of iron core will lead to insulation aging.

The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side), and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring, and D (or D) is triangular wiring.

Gradually,Bacalita110kV transformer, high-frequency vibration damping mechanical equipment, such as low-frequency vibration damping platform, is installed at the bottom of the dry-type transformer which can reduce the downward dispersion of the vibration of the dry-type transformer. Then replace the connection between the dry-type transformer and the surrounding engineering buildings, roads etc. with flexible connection, or use elastic yellow shock absorption mechanical equipment to prevent the vibration from spreading according to the rigid connection. If possible, the dry-type transformer room can also be soundproofed and decorated, and sound-absorbing plates and silencing shutters can be used to improve the soundproofing capacity of the dry-type transformer room.
