According to the condition of cracks， galvanized iron wire can be punched into the leakage or riveted with hammer. Then clean the leakage point with toluene and seal it with raw materials. Coated sand casting eyes can be sealed with raw materials immediately.
For no-load impulse closing of transformer， and a guardrail of no less than m shall be installed around it， and a warning sign shall be hung at a prominent position.
The raw materials of Fushi blue can be used for bonding， so that the overall oil leakage of the connector can be greatly controlled; If the actual operation is convenient，Kur ī gr ā Zone MDifference between dry-type transformer and oil immersed transformer， the metal shell can also be bonded at the same time to achieve the purpose of leakage treatment.
Brief introduction of zero line of power transformer
When checking the hook core， the insulation of the electromagnetic coil and the porcelain sleeve is usually accidentally damaged. After the shell of the pottery is broken， if you work again， turn on the photo flash when it"s light， and it"s short when it"s heavy. Therefore， please pay attention during maintenance. It is not necessary to destroy the insulation. After maintenance， experts can inspect special tools， parts， insulation， etc. and deliver them after they are determined to be complete and reliable.
Once the insulation material of electrical equipment is overheated， the surrounding gas will cause a kind of odor. This kind of odor can be sniffed out by normal patrol staff. When you smell such odor during normal inspection， you should carefully inspect the equipment and parts until you find out the cause.

When the transformer is out of phase， if the second phase is blocked， there is still no sound when the second phase is sent， and there is sound when the third phase is sent; If the third phase is blocked， which are called test power transformers. They can be divided into inflatable as in the case of the second phase. There are three reasons for phase deficiency:
Power transformers are also used for testing， oil transformer， dry test and other test power transformers. They are the basic test equipment for communication AC compression test for many consumers such as power stations， power supply bureaus and scientific research institutions. According to the specifications of the Bureau of quality supervision It is used to carry out insulation compressive strength test under required current for various electrical products， electrical components and insulating raw materials.
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，Kur ī gr ā Zone MScb14 dry type transformer， short circuit fault between boxes， two-color short circuit fault or short circuit to ground fault and dissolution of oil.
Production departmentBefore no-load impact closing， the pose period of overcurrent protection shall be set to zero， and the data signal circuit of steam vehicle relay shall be temporarily connected to the pull-in circuit.
The person in charge of a transformer manufacturer said that because of the hazards of raw materials and other factors， the cost of energy-saving transformers is significantly higher than that of traditional transformers and the price factor is also a key factor endangering the popularization and marketing of energy-saving transformers. Although there are energy-saving and convenient subsidy projects to help energy-saving transformers， the market has not yet fully operated.
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， but also make the transformer operate at full load or load for a long time， expand the proportion of full load loss，Kur ī gr ā Zone MWhich is a good dry-type test transformer， reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.
Kur ī gr ā Zone MUnder normal conditions， the actual operation of the oil immersed transformer shall be undertaken by the on-site operation and maintenance management staff. Within one week of grid connected operation， the operation and maintenance management staff shall improve the safety inspection range of the transformer， and immediately communicate and contact with the on-site project staff in case of any problems， so as to ensure the reliable and stable operation of machinery and equipment.
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 -A / Min.
