Krasnoyarsk220special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage, it shall be handled properly.
The hanging core of dry-type transformer is a vital part
waddan .The equipment can eliminate the shortcomings found in the patrol inspection, 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, etc.
Plug in the power with full load first, observe and detect that the input and output voltage meets the regulations. At the same time, check whether the equipment has abnormal sound, ignition,waddan Introduction to dry type transformer,waddan Dry type transformer 10 / 0.4kV, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.
.In relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word, it will affect the whole power circuit
From the appearance, the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer, the power transformer will be transported and sent to the power consuming machines and equipment. What is the zero line of the actual power transformer? Let's introduce it to us.
Under 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 efficiency of transformer is closely related to the output power level of transformer. Generally, the greater the output power, the smaller the loss to output power ratio and the higher the efficiency. On the contrary, the smaller the output power, the lower the efficiency.

(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,waddan Distribution transformer model, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.
Standard requirements.What is the important role of power transformer
In fact, apart from the application of the Finance Bureau, the industry has been trying to formulate and upgrade transformer commodities according to the specifications, so as to promote the improvement of energy consumption level of transformer commodities.
The method and whole process of taking oil sample of power transformer are as follows:
waddan .Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer, special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage, it shall be handled properly.
Then clamp the branch pipe with your thumb, clearly put forward the glass test tube rotate and release the oil in the tube to clean the sampling tube, carry out it twice, and then draw the oil sample.
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, so as to meet the needs of power consumption. In short, voltage transformation and blood pressure reduction must be carried out by the transformer.
