Winter tourismS13 oil immersed transformerWhat aspects should be paid attention to when purchasing

a great & ldquo; Tweet & rdquo; The high-voltage fuse is broken when the noise is serious; If the tap changer is defective if the tap changer is not in time

When the transformer is put into operation, 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, power off immediately for maintenance.

In order to better reduce the probability of short-circuit fault of relay protection dry-type transformer, clean the porcelain waterproof casing casing, remove and replace the cracked or brittle leather pad, check and tighten the node, replenish the oil with less oil, check and replace the silica gel of the breathing mask,Winter tourismAmorphous alloy distribution transformer, etc.

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.

.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.

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

Note: in the whole process of safety patrol inspection, the on-site operation and maintenance management staff must use temperature tester or thermal imager to carry out purposeful inspection on the transformer itself, significantly expanded, or there is local sound, the cause shall be found immediately and certain effective measures shall be taken. If necessary, the load can be reduced or the operation of the transformer can be stopped.

The power transformer is composed of two or more electromagnetic coils wound around the same transformer core. The winding resistance is connected according to the alternating electromagnetic field and works according to the basic principle of magnetic effect of current. The installation position of power transformer shall be considered to be conducive to operation, maintenance and transportation and a reliable area shall be selected at the same time. The rated capacity of the transformer must be effectively used when applying the transformer.

Automatic system of centrifugal fan: measure the temperature data signal according to the PT100 thermistor temperature measuring resistor of the embedded parts at the hot part of the bottom pressure winding. The transformer load expands and the operating temperature increases. When the winding temperature reaches 110 ℃, the system software automatically starts the centrifugal fan for refrigeration; When the winding temperature is as low as 90 ℃, the system software will automatically terminate the centrifugal fan.

Dry type transformer

average method.From the appearance, and only the shell can be seen for oil immersed transformer;

In the whole process of transmitting electromagnetic energy in the power supply system, it will inevitably cause the loss of voltage and output power. When transporting the same output power, the voltage loss is inversely proportional to the voltage,Winter tourism480v dry type transformer, and the output power loss is inversely proportional to the square meter of voltage. The transformer is used to increase the voltage and reduce the closing damage.

During no-load test run, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.

Power transformer is one of the key equipment in power station and substation. The function of power transformer is in all aspects. It can not only raise the voltage and send electromagnetic energy to the power consumption area, but also reduce the voltage to each application voltage,Winter tourismLatest model of oil immersed transformer, so as to meet the needs of power consumption. In short, voltage transformation and blood pressure reduction must be carried out by the transformer.

Packaging strategy.Wiring mode of dry-type transformer:

The transformer manufacturer will introduce the efficiency of the transformer to you

Avoid the load operation of power transformer: if the load operation is long-term, it will lead to the scalding of solenoid coil, slow aging of insulation, short circuit fault between boxes, two-color short circuit fault or short circuit to ground fault and dissolution of oil.

Winter tourism.Sound in case of phase failure

From the appearance, the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer, and only the shell can be seen for oil immersed transformer;

The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions, including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.
